- "The function used in `helm-find-files' to list remote directories.
-
-Actually helm provides two functions to do this: `helm-list-dir-lisp'
-and `helm-list-dir-external'.
-
-Using `helm-list-dir-external' will provides a similar display to what
-provided with local files i.e. colorized symlinks, executables files
-etc... whereas using `helm-list-dir-lisp' will allow colorizing only
-directories but is more portable.
-
-NOTE that `helm-list-dir-external' needs ls and awk as dependencies."

- "grep --color=always -a -d skip %e -n%cH -e %p %f"
- "Default grep format command for `helm-do-grep-1'.
-Where:
-'%e' format spec is for --exclude or --include grep options or
- ack-grep --type option. (Not mandatory)
-
-'%c' format spec is for case-fold-search,
- whether to use the -i option of grep. (Not mandatory)
- When you specify this spec, helm grep will use smartcase
- that is when a upcase character is found in pattern case will
- be respected and no '-i' option will be used, otherwise, when
- no upcase character is found in pattern always use '-i'.
- If you don't want this behavior, don't use this spec and
- specify or not the '-i' option.
- Note that with ack-grep this is not needed, just specify
- the '--smart-case' option.
-
-'%p' format spec is for pattern. (Mandatory)
-
-'%f' format spec is for filenames. (Mandatory)
-
-If your grep version doesn't support the --exclude/include args
-don't specify the '%e' format spec.
-
-Helm also support ack-grep and git-grep ,
-here a default command example for ack-grep:
-
-\(setq helm-grep-default-command \"ack-grep -Hn --color --smart-case --no-group %e %p %f\"
- helm-grep-default-recurse-command \"ack-grep -H --color --smart-case --no-group %e %p %f\")
-
-You can ommit the %e spec if you don't want to be prompted for types.
-
-NOTE: Helm for ack-grep support ANSI sequences, so you can remove
-the \"--no-color\" option safely (recommended)
-However you should specify --color to enable multi matches highlighting
-because ack disable it when output is piped.
-
-Same for grep you can use safely the option \"--color=always\" (default).
-You can customize the color of matches using GREP_COLORS env var.
-e.g: \(setenv \"GREP_COLORS\" \"ms=30;43:mc=30;43:sl=01;37:cx=:fn=35:ln=32:bn=32:se=36\")
-
-To enable ANSI color in git-grep just add \"--color=always\".
-To customize the ANSI color in git-grep, GREP_COLORS have no effect,
-you will have to setup this in your .gitconfig:
-
- [color \"grep\"]
- match = black yellow
-
-where \"black\" is the foreground and \"yellow\" the background.
-See the git documentation for more infos.
-
-`helm-grep-default-command' and `helm-grep-default-recurse-command'are
-independents, so you can enable `helm-grep-default-command' with ack-grep
-and `helm-grep-default-recurse-command' with grep if you want to be faster
-on recursive grep.
-
-NOTE: Remote grepping is not available with ack-grep,
- and badly supported with grep because tramp handle badly
- repeated remote processes in a short delay (< to 5s)."

- "* Helm Buffer
-
-** Tips
-
-*** Completion
-
-**** Major-mode
-
-You can enter a partial major-mode name (e.g. lisp, sh) to narrow down buffers.
-To specify the major-mode, prefix it with \"*\" e.g. \"*lisp\".
-
-If you want to match all buffers but the ones with a specific major-mode
-\(negation), prefix the major-mode with \"!\" e.g. \"*!lisp\".
-
-If you want to specify more than one major-mode, separate them with \",\",
-e.g. \"*!lisp,!sh,!fun\" lists all buffers but the ones in lisp-mode, sh-mode
-and fundamental-mode.
-
-Then enter a space followed by a pattern to narrow down to buffers matching this
-pattern.
-
-**** Search inside buffers
-
-If you enter a space and a pattern prefixed by \"@\", Helm searches for text
-matching this pattern \*inside* the buffer (i.e. not in the name of the buffer).
-
-If you enter a pattern prefixed with an escaped \"@\", Helm searches for a
-buffer matching \"@pattern\" but does not search inside.
-
-**** Search by directory name
-
-If you prefix the pattern with \"/\", Helm matches over the directory names
-of the buffers.
-
-This feature can be used to narrow down the search to one directory while
-subsequent strings entered after a space match over the buffer name only.
-
-Note that negation is not supported for matching on buffer filename.
-
-Starting from Helm v1.6.8, you can specify more than one directory.
-
-**** Fuzzy matching
-
-`helm-buffers-fuzzy-matching' turns on fuzzy matching on buffer names, but not
-on directory names or major modes. A pattern starting with \"^\" disables fuzzy
-matching and matches by exact regexp.
-
-**** Examples
-
-With the following pattern
-
- \"*lisp ^helm @moc\"
-
-Helm narrows down the list by selecting only the buffers that are in lisp mode,
-start with \"helm\" and which content matches \"moc\".
-
-Without the \"@\"
-
- \"*lisp ^helm moc\"
-
-Helm looks for lisp mode buffers starting with \"helm\" and containing \"moc\"
-in their name.
-
-With this other pattern
-
- \"*!lisp !helm\"
-
-Helm narrows down to buffers that are not in \"lisp\" mode and that do not match
-\"helm\".
-
-With this last pattern
-
- /helm/ w3
-
-Helm narrows down to buffers that are in any \"helm\" subdirectory and
-matching \"w3\".
-
-*** Creating buffers
-
-When creating a new buffer, use `\\[universal-argument]' to choose a mode from a
-list. This list is customizable, see `helm-buffers-favorite-modes'.
-
-*** Killing buffers
-
-You can kill buffers either one by one or all the marked buffers at once.
-
-One kill-buffer command leaves Helm while the other is persistent. Run the
-persistent kill-buffer command either with the regular
-`helm-execute-persistent-action' called with a prefix argument (`\\[universal-argument] \\<helm-map>\\[helm-execute-persistent-action]')
-or with its specific command `helm-buffer-run-kill-persistent'. See the
-bindings below.
-
-*** Switching to buffers
-
-To switch to a buffer, press RET, to switch to a buffer in another window, select this buffer
-and press \\<helm-buffer-map>\\[helm-buffer-switch-other-window], when called with a prefix arg
-the buffer will be displayed vertically in other window.
-If you mark more than one buffer, the marked buffers will be displayed in different windows.
-
-*** Meaning of colors and prefixes for buffers
-
-Remote buffers are prefixed with '@'.
-Red => Buffer's file was modified on disk by an external process.
-Indianred2 => Buffer exists but its file has been deleted.
-Orange => Buffer is modified and not saved to disk.
-Italic => A non-file buffer.
-Yellow => Tramp archive buffer.
-

-(defvar helm-ff-help-message
- "* Helm Find Files
-
-** Tips
-
-*** Navigation summary
-
-For a better experience you can enable auto completion by setting
-`helm-ff-auto-update-initial-value' to non-nil in your init file. It is not
-enabled by default to not confuse new users.
-
-**** Use `\\<helm-find-files-map>\\[helm-execute-persistent-action]' (persistent action) on a directory to go down one level
-
-On a symlinked directory a prefix argument expands to its true name.
-
-**** Use `\\<helm-find-files-map>\\[helm-find-files-up-one-level]' on a directory to go up one level
-
-**** Use `\\<helm-find-files-map>\\[helm-find-files-down-last-level]' to walk back the resulting tree of all the `\\<helm-map>\\[helm-execute-persistent-action]' you did
-
-The tree is reinitialized each time you browse a new tree with
-`\\<helm-map>\\[helm-execute-persistent-action]' or by entering some pattern in the prompt.
-
-**** `RET' behavior
-
-It behaves differently depending on `helm-selection' (current candidate in helm-buffer):
-
-- candidate basename is \".\" => Open it in dired.
-- candidate is a directory => Expand it.
-- candidate is a file => Open it.
-
-If you have marked candidates and you press RET on a directory,
-helm will navigate to this directory, if you want to exit with
-RET with default action with these marked candidates, press RET
-on a second time while you are on the root of this directory
-e.g. \"/home/you/dir/.\" or press RET on any file which is not a
-directory. You can also exit with default action at any moment
-with `f1'.
-
-Note that when copying, renaming, etc. from `helm-find-files' the
-destination file is selected with `helm-read-file-name'.
-
-To avoid confusion when using `read-file-name' or `read-directory-name', `RET'
-follows its standard Emacs behaviour, i.e. it exits the minibuffer as soon as
-you press `RET'. If you want the same behavior as in `helm-find-files', bind
-`helm-ff-RET' to the `helm-read-file-map':
-
- (define-key helm-read-file-map (kbd \"RET\") 'helm-ff-RET)
-
-*** Find file at point
-
-Helm uses `ffap' partially or completely to find file at point depending on the
-value of `helm-ff-guess-ffap-filenames': if non-nil, support is complete
-\(annoying), if nil, support is partial.
-
-**** Find file at line number
-
-When text at point is in the form of
-
- ~/elisp/helm/helm.el:1234
-
-Helm finds this file at the indicated line number, here 1234.
-
-**** Find URL at point
-
-When a URL is found at point, Helm expands to that URL only.
-Pressing `RET' opens that URL using `browse-url-browser-function'.
-
-**** Find e-mail address at point
-
-When an e-mail address is found at point, Helm expands to this e-mail address
-prefixed with \"mailto:\". Pressing `RET' opens a message buffer with that
-e-mail address.
-
-*** Quick pattern expansion
-
-**** Enter `~/' at end of pattern to quickly reach home directory
-
-**** Enter `/' at end of pattern to quickly reach the file system root
-
-**** Enter `./' at end of pattern to quickly reach `default-directory'
-
-\(As per its value at the beginning of the session.)
-
-If you already are in the `default-directory' this will move the cursor to the top.
-
-**** Enter `../' at end of pattern will reach upper directory, moving cursor to the top
-
-This is different from using `\\<helm-find-files-map>\\[helm-find-files-up-one-level]' in that it moves
-the cursor to the top instead of remaining on the previous subdir name.
-
-**** Enter `..name/' at end of pattern to start a recursive search
-
-It searches directories matching \"name\" under the current directory, see the
-\"Recursive completion on subdirectories\" section below for more details.
-
-**** Any environment variable (e.g. `$HOME') at end of pattern gets expanded
-
-**** Any valid filename yanked after pattern gets expanded
-
-**** Special case: URL at point
-
-The quick expansions do not take effect after end a URL, you must kill the
-pattern first (`\\[helm-delete-minibuffer-contents]').
-
-*** Helm-find-files supports fuzzy matching
-
-It starts from the third character of the pattern.
-
-For instance \"fob\" or \"fbr\" will complete \"foobar\" but \"fb\" needs a
-third character in order to complete it.
-
-*** Use `\\[universal-argument] \\[helm-execute-persistent-action]' or `\\[helm-follow-action-forward]' to display an image
-
-*** `\\[helm-execute-persistent-action]' on a filename expands to that filename in the Helm buffer
-
-Second hit displays the buffer filename.
-Third hit kills the buffer filename.
-Note: `\\[universal-argument] \\[helm-execute-persistent-action]' displays the buffer directly.
-
-*** Browse images directories with `helm-follow-mode' and navigate up/down
-
-You can also use `helm-follow-action-forward' and `helm-follow-action-backward' with
-`\\[helm-follow-action-forward]' and `\\[helm-follow-action-backward]' respectively.
-
-*** Toggle auto-completion with `\\[helm-ff-run-toggle-auto-update]'
-
-It is useful when trying to create a new file or directory and you don't want
-Helm to complete what you are writing.
-
-Note: On a terminal, the default binding `C-<backspace>' may not work.
-In this case use `C-c <backspace>'.
-
-*** You can create a new directory and a new file at the same time
-
-Simply write the path in the prompt and press `RET', e.g.
-\"~/new/newnew/newnewnew/my_newfile.txt\".
-
-*** To create a new directory, append a \"/\" to the new name and press `RET'
-
-*** To create a new file, enter a filename not ending with \"/\"
-
-Note that when you enter a new name, this one is prefixed with
-\[?] if you are in a writable directory. If you are in a directory
-where you have no write permission the new file name is not
-prefixed and is colored in red. There is not such distinction
-when using tramp, new filename just appear on top of buffer.
-
-*** Recursive search from Helm-find-files
-
-**** You can use Helm-browse-project (see binding below)
-
-- With no prefix argument:
-If the current directory is under version control with either git or hg and
-helm-ls-git and/or helm-ls-hg are installed, it lists all the files under
-version control. Otherwise it falls back to Helm-find-files. See
-https://github.com/emacs-helm/helm-ls-git and
-https://github.com/emacs-helm/helm-ls-hg.
-
-- With one prefix argument:
-List all the files under this directory and other subdirectories
-\(recursion) and this list of files will be cached.
-
-- With two prefix arguments:
-Same but the cache is refreshed.
-
-**** You can start a recursive search with \"locate\" or \"find\"
-
-See \"Note\" in the [[Recursive completion on subdirectories][section on subdirectories]].
-
-Using \"locate\", you can enable the local database with a prefix argument. If the
-local database doesn't already exists, you will be prompted for its creation.
-If it exists and you want to refresh it, give it two prefix args.
-
-When using locate the helm-buffer remains empty until you type something.
-Regardless Helm uses the basename of the pattern entered in the helm-find-files
-session by default. Hitting `\\[next-history-element]' should just kick in the
-locate search with this pattern. If you want Helm to automatically do this, add
-`helm-source-locate' to `helm-sources-using-default-as-input'.
-
-**** Recursive completion on subdirectories
-
-Starting from the directory you are currently browsing, it is possible to have
-completion of all directories underneath. Say you are at \"/home/you/foo/\" and
-you want to go to \"/home/you/foo/bar/baz/somewhere/else\", simply type
-\"/home/you/foo/..else\" and hit `\\[helm-execute-persistent-action]' or enter
-the final \"/\". Helm will then list all possible directories under \"foo\"
-matching \"else\".
-
-Entering two spaces before \"else\" instead of two dots also works.
-
-Note: Completion on subdirectories uses \"locate\" as backend, you can configure
-the command with `helm-locate-recursive-dirs-command'. Because this completion
-uses an index, the directory tree displayed may be out-of-date and not reflect
-the latest change until you update the index (using \"updatedb\" for \"locate\").
-
-If for some reason you cannot use an index, the \"find\" command from
-\"findutils\" can be used instead. It will be slower though. You need to pass
-the basedir as first argument of \"find\" and the subdir as the value for
-'-(i)regex' or '-(i)name' with the two format specs that are mandatory in
-`helm-locate-recursive-dirs-command'.
-
-Examples:
-- \"find %s -type d -name '*%s*'\"
-- \"find %s -type d -regex .*%s.*$\"
-
-*** Insert filename at point or complete filename at point
-
-On insertion (not on completion, i.e. there is nothing at point):
-
-- `\\[helm-ff-run-complete-fn-at-point]': insert absolute file name.
-- `\\[universal-argument] \\[helm-ff-run-complete-fn-at-point]': insert abbreviated file name.
-- `\\[universal-argument] \\[universal-argument] \\[helm-ff-run-complete-fn-at-point]': insert relative file name.
-- `\\[universal-argument] \\[universal-argument] \\[universal-argument] \\[helm-ff-run-complete-fn-at-point]': insert basename.
-
-On completion:
-
-- Target starts with \"~/\": insert abbreviate file name.
-- target starts with \"/\" or \"[a-z]:/\": insert full path.
-- Otherwise: insert relative file name.
-
-*** Use the wildcard to select multiple files
-
-Use of wilcard is supported to run an action over a set of files.
-
-Example: You can copy all the files with \".el\" extension by using \"*.el\" and
-then run copy action.
-
-Similarly, \"**.el\" (note the two stars) will recursively select all \".el\"
-files under the current directory.
-
-Note that when recursively copying files, you may have files with same name
-dispatched across different subdirectories, so when copying them in the same
-directory they will get overwritten. To avoid this Helm has a special action
-called \"backup files\" that has the same behavior as the command line \"cp -f
---backup=numbered\": it allows you to copy many files with the same name from
-different subdirectories into one directory. Files with same name are renamed
-as follows: \"foo.txt.~1~\". Like with the --force option of cp, it is possible
-to backup files in current directory.
-
-This command is available only when `dired-async-mode' is active.
-
-When using an action that involves an external backend (e.g. grep), using \"**\"
-is not recommended (even thought it works fine) because it will be slower to
-select all the files. You are better off leaving the backend to do it, it will
-be faster. However, if you know you have not many files it is reasonable to use
-this, also using not recursive wilcard (e.g. \"*.el\") is perfectly fine for
-this.
-
-The \"**\" feature is active by default in the option `helm-file-globstar'. It
-is different from the Bash \"shopt globstar\" feature in that to list files with
-a named extension recursively you would write \"**.el\" whereas in Bash it would
-be \"**/*.el\". Directory selection with \"**/\" like Bash \"shopt globstar\"
-option is not supported yet.
-
-*** Query replace regexp on filenames
-
-Replace different parts of a file basename with something else.
-
-When calling this action you will be prompted twice as with
-`query-replace', first for the matching expression of the text to
-replace and second for the replacement text. Several facilities,
-however, are provided to make the two prompts more powerfull.
-
-**** Syntax of the first prompt
-
-In addition to simple regexps, these shortcuts are available:
-
-- Basename without extension => \"%.\"
-- Only extension => \".%\"
-- Substring => \"%:<from>:<to>\"
-- Whole basename => \"%\"
-
-**** Syntax of the second prompt
-
-In addition to a simple string to use as replacement, here is what you can use:
-
-- A placeholder refering to what you have selected in the first prompt: \"\\@\".
-
-After this placeholder you can use a search-and-replace syntax à-la sed:
-
- \"\\@/<regexp>/<replacement>/
-
-You can select a substring from the string represented by the placeholder:
-
- \"\\@:<from>:<to>\"
-
-- A special character representing a number which is incremented: \"\\#\".
-
-- Shortcuts for `upcase', `downcase' and `capitalize'
-are available as`%u', `%d' and `%c' respectively.
-
-**** Examples
-
-***** Recursively rename all files with \".JPG\" extension to \".jpg\"
-
-Use the `helm-file-globstar' feature described in [[Use the wildcard to select multiple files][recursive globbing]]
-by entering \"**.JPG\" at the end of the Helm-find-files pattern, then hit
-\\<helm-map>\\[helm-ff-query-replace-on-filenames]: First \"JPG\", then \"jpg\"
-and hit `RET'.
-
-Alternatively you can enter \".%\" at the first prompt, then \"jpg\" and hit
-`RET'. Note that when using this instead of using \"JPG\" at the first prompt,
-all extensions will be renamed to \"jpg\" even if the extension of one of the
-files is, say, \"png\". If you want to keep the original extension you can use
-\"%d\" at the second prompt (downcase).
-
-***** Batch-rename files from number 001 to 00x
-
-Use \"\\#\" inside the second prompt.
-
-Example 1: To rename the files
-
- foo.jpg
- bar.jpg
- baz.jpg
-
-to
-
- foo-001.jpg
- foo-002.jpg
- foo-003.jpg
-
-use \"%.\" as matching regexp and \"foo-\\#\" as replacement string.
-
-Example 2: To rename the files
-
- foo.jpg
- bar.jpg
- baz.jpg
-
-to
-
- foo-001.jpg
- bar-002.jpg
- baz-003.jpg
-
-use as matching regexp \"%.\" and as replacement string \"\\@-\\#\".
-
-***** Replace a substring
-
-Use \"%:<from>:<to>\".
-
-Example: To rename files
-
- foo.jpg
- bar.jpg
- baz.jpg
-
-to
-
- fOo.jpg
- bAr.jpg
- bAz.jpg
-
-use as matching regexp \"%:1:2\" and as replacement string \"%u\" (upcase).
-
-Note that you \*cannot* use \"%.\" and \".%\" along with substring replacement.
-
-***** Modify the string from the placeholder (\\@)
-
-- By substring, i.e. only using the substring of the placeholder: \"\\@:<from>:<to>\".
-The length of placeholder is used for <to> when unspecified.
-
-Example 1: \"\\@:0:2\" replaces from the beginning to the second char of the placeholder.
-
-Example 2: \\@:2: replaces from the second char of the placeholder to the end.
-
-- By search-and-replace: \"\\@/<regexp>/<replacement>/\".
-
-Incremental replacement is also handled in <replacement>.
-
-Example 3: \"\\@/foo/bar/\" replaces \"foo\" by \"bar\" in the placeholder.
-
-Example 4: \"\\@/foo/-\\#/\" replaces \"foo\" in the placeholder by 001, 002, etc.
-
-***** Clash in replacements (avoid overwriting files)
-
-When performing any of these replacement operations you may end up with same
-names as replacement. In such cases Helm numbers the file that would otherwise
-overwritten. For instance, should you remove the \"-m<n>\" part from the files
-\"emacs-m1.txt\", \"emacs-m2.txt\" and \"emacs-m3.txt\" you would end up with
-three files named \"emacs.txt\", the second renaming overwriting first file, and
-the third renaming overwriting second file and so on. Instead Helm will
-automatically rename the second and third files as \"emacs(1).txt\" and
-\"emacs(2).txt\" respectively.
-
-***** Query-replace on filenames vs. serial-rename action
-
-Unlike the [[Serial renaming][serial rename]] actions, the files renamed with
-the query-replace action stay in their initial directory and are not moved to
-the current directory. As such, using \"\\#\" to serial-rename files only makes
-sense for files inside the same directory. It even keeps renaming files
-with an incremental number in the next directories.
-
-*** Serial renaming
-
-You can use the serial-rename actions to rename, copy or symlink marked files to
-a specific directory or in the current directory with all the files numbered
-incrementally.
-
-- Serial-rename by renaming:
-Rename all marked files with incremental numbering to a specific directory.
-
-- Serial-rename by copying:
-Copy all marked files with incremental numbering to a specific directory.
-
-- Serial-rename by symlinking:
-Symlink all marked files with incremental numbering to a specific directory.
-
-*** Edit marked files in a dired buffer
-
-You can open a dired buffer containing only marked files with `\\<helm-find-files-map>\\[helm-ff-run-marked-files-in-dired]'.
-With a prefix argument you can open this same dired buffer in wdired mode for
-editing. Note that wildcards are supported as well, so you can use e.g.
-\"*.txt\" to select all \".txt\" files in the current directory or \"**.txt\" to
-select all files recursively from the current directory.
-See [[Use the wildcard to select multiple files]] section above.
-
-*** Defining default target directory for copying, renaming, etc
-
-You can customize `helm-dwim-target' to behave differently depending on the
-windows open in the current frame. Default is to provide completion on all
-directories associated to each window.
-
-*** Copying and renaming asynchronously
-
-If you have the async library installed (if you got Helm from MELPA you do), you
-can use it for copying/renaming files by enabling `dired-async-mode'.
-
-Note that even when async is enabled, running a copy/rename action with a prefix
-argument will execute action synchronously. Moreover it will follow the first
-file of the marked files in its destination directory.
-
-When `dired-async-mode' is enabled, an additional action named \"Backup files\"
-will be available. (Such command is not natively available in Emacs).
-See [[Use the wildcard to select multiple files]] for details.
-
-*** Bookmark the `helm-find-files' session
-
-You can bookmark the `helm-find-files' session with `\\[helm-ff-bookmark-set]'.
-You can later retrieve these bookmarks by calling `helm-filtered-bookmarks'
-or, from the current `helm-find-files' session, by hitting `\\[helm-find-files-toggle-to-bookmark]'.
-
-*** Grep files from `helm-find-files'
-
-You can grep individual files from `helm-find-files' by using
-\`\\<helm-find-files-map>\\[helm-ff-run-grep]'. This same command can also
-recursively grep files from the current directory when called with a prefix
-argument. In this case you will be prompted for the file extensions to use
-\(grep backend) or the types of files to use (ack-grep backend). See the
-`helm-grep-default-command' documentation to set this up. For compressed files
-or archives, use zgrep with \`\\<helm-find-files-map>\\[helm-ff-run-zgrep]'.
-
-Otherwise you can use recursive commands like \`\\<helm-find-files-map>\\[helm-ff-run-grep-ag]' or `\\<helm-find-files-map>\\[helm-ff-run-git-grep]'
-that are much faster than using `\\<helm-find-files-map>\\[helm-ff-run-grep]' with a prefix argument.
-See `helm-grep-ag-command' and `helm-grep-git-grep-command' to set this up.
-
-You can also use \"id-utils\"' GID with \`\\<helm-find-files-map>\\[helm-ff-run-gid]'
-by creating an ID index file with the \"mkid\" shell command.
-
-All those grep commands use the symbol at point as the default pattern.
-Note that default is different from input (nothing is added to the prompt until
-you hit `\\[next-history-element]').
-
-**** Grepping on remote files
-
-On remote files grep is not well supported by TRAMP unless you suspend updates before
-entering the pattern and re-enable it once your pattern is ready.
-To toggle suspend-update, use `\\<helm-map>\\[helm-toggle-suspend-update]'.
-
-*** Setting up aliases in Eshell allows you to set up powerful customized commands
-
-Adding Eshell aliases to your `eshell-aliases-file' or using the
-`alias' command from Eshell allows you to create personalized
-commands not available in `helm-find-files' actions and use them
-from `\\<helm-find-files-map>\\[helm-ff-run-eshell-command-on-file]'.
-
-Example: You want a command to uncompress some \"*.tar.gz\" files from `helm-find-files':
-
-1) Create an Eshell alias named, say, \"untargz\" with the command
-\"alias untargz tar zxvf $*\".
-
-2) Now from `helm-find-files' select the \"*.tar.gz\" file (you can also
-mark files if needed) and hit `\\<helm-find-files-map>\\[helm-ff-run-eshell-command-on-file]'.
-
-Note: When using marked files with this, the meaning of the prefix argument is
-quite subtle. Say you have \"foo\", \"bar\" and \"baz\" marked; when you run
-the alias command `example' on these files with no prefix argument it will run
-`example' sequentially on each file:
-
-$ example foo
-$ example bar
-$ example baz
-
-With a prefix argument however it will apply `example' on all files at once:
-
-$ example foo bar baz
-
-Of course the alias command should support this.
-
-*** Using TRAMP with `helm-find-files' to read remote directories
-
-`helm-find-files' works fine with TRAMP despite some limitations.
-
-- Grepping files is not very well supported when used incrementally.
-See [[Grepping on remote files]].
-
-- Locate does not work on remote directories.
-
-**** A TRAMP syntax crash course
-
-Please refer to TRAMP's documentation for more details.
-
-- Connect to host 192.168.0.4 as user \"foo\":
-
-/scp:192.168.0.4@foo:
-
-- Connect to host 192.168.0.4 as user \"foo\" on port 2222:
-
-/scp:192.168.0.4@foo#2222:
-
-- Connect to host 192.168.0.4 as root using multihops syntax:
-
-/ssh:192.168.0.4@foo|sudo:192.168.0.4:
-
-Note: You can also use `tramp-default-proxies-alist' when connecting often to
-the same hosts.
-
-As a rule of thumb, prefer the scp method unless using multihops (which only
-works with the ssh method), especially when copying large files.
-
-You need to hit `C-j' once on top of a directory on the first connection
-to complete the pattern in the minibuffer.
-
-**** Display color for directories, symlinks etc... with tramp
-
-Starting at helm version 2.9.7 it is somewhat possible to
-colorize fnames by listing files without loosing performances with
-external commands (ls and awk) if your system is compatible.
-For this you can use `helm-list-dir-external' as value
-for `helm-list-directory-function'.
-
-See `helm-list-directory-function' documentation for more infos.
-
-**** Completing host
-
-As soon as you enter the first \":\" after method e.g =/scp:= you will
-have some completion about previously used hosts or from your =~/.ssh/config=
-file, hitting `\\[helm-execute-persistent-action]' or `right' on a candidate will insert this host in minibuffer
-without addind the ending \":\", second hit insert the last \":\".
-As soon the last \":\" is entered TRAMP will kick in and you should see the list
-of candidates soon after.
-
-When connection fails, be sure to delete your TRAMP connection with M-x
-`helm-delete-tramp-connection' before retrying.
-
-**** Editing local files as root
-
-Use the sudo method:
-
-\"/sudo:host:\" or simply \"/sudo::\".
-
-*** Attach files to a mail buffer (message-mode)
-
-If you are in a `message-mode' or `mail-mode' buffer, that action will appear
-in action menu, otherwise it is available at any time with \\<helm-find-files-map>\\[helm-ff-run-mail-attach-files].
-It behaves as follows:
-
-- If you are in a (mail or message) buffer, files are attached there.
-
-- If you are not in a mail buffer but one or more mail buffers exist, you are
-prompted to attach files to one of these mail buffers.
-
-- If you are not in a mail buffer and no mail buffer exists,
-a new mail buffer is created with the attached files in it.
-
-*** Open files in separate windows
-
-When [[Marked candidates][marking]] multiple files or using [[Use the wildcard to select multiple files][wildcard]], helm allow opening all
-this files in separate windows using an horizontal layout or a
-vertical layout if you used a prefix arg, when no more windows can be
-displayed in frame, next files are opened in background without being
-displayed. When using \\<helm-find-files-map>\\[helm-ff-run-switch-other-window] the current
-buffer is kept and files are displayed next to it with same behavior as above.
-When using two prefix args, files are opened in background without beeing displayed.
-
-*** Expand archives as directories in a avfs directory
-
-If you have mounted your filesystem with mountavfs,
-you can expand archives in the \"~/.avfs\" directory with \\<helm-map>\\[helm-execute-persistent-action].
-
-*** Tramp archive support (emacs-27+ only)
-
-If your emacs have library tramp-archive.el, you can browse the
-content of archives with emacs and BTW helm-find-files. However this beeing
-experimental and not very fast, helm doesn't provide an automatic
-expansion and detection of archives, you will have to add the final /
-manually and may have to force update (\\<helm-map>\\[helm-refresh])
-or remove and add again the final / until tramp finish decompressing archive.
-
-*** Touch files
-
-In the completion buffer, you can choose the default which is the current-time, it is
-the first candidate or the timestamp of one of the selected files.
-If you need to use something else, use \\<helm-map>\\[next-history-element] and edit
-the date in minibuffer.
-It is also a way to quickly create a new file without opening a buffer, saving it
-and killing it.
-To touch more than one new file, separate you filenames with a comma (\",\").
-If one wants to create (touch) a new file with comma inside the name use a prefix arg,
-this will prevent splitting the name and create multiple files.
-
-*** Delete files
-
-You can delete files without quitting helm with
-`\\<helm-find-files-map>\\[helm-ff-persistent-delete]' or delete files and quit helm with `\\[helm-ff-run-delete-file]'.
-
-In the second method you can choose to
-make this command asynchronous by customizing
-\`helm-ff-delete-files-function'.
-
-_WARNING_: When deleting files asynchronously you will NOT be
-WARNED if directories are not empty, that's mean non empty directories will
-be deleted in background without asking.
-
-A good compromise is to trash your files
-when using asynchronous method (see [[Trashing files][Trashing files]]).
-
-When choosing synchronous delete, you can allow recursive
-deletion of directories with `helm-ff-allow-recursive-deletes'.
-Note that when trashing (synchronous) you are not asked for recursive deletion.
-
-Note that `helm-ff-allow-recursive-deletes' have no effect when
-deleting asynchronously.
-
-First method (persistent delete) is always synchronous.
-
-Note that when a prefix arg is given, trashing behavior is inversed.
-See [[Trashing files][Trashing files]].
-
-**** Trashing files
-
-If you want to trash your files instead of deleting them you can
-set `delete-by-moving-to-trash' to non nil, like this your files
-will be moved to trash instead of beeing deleted.
-
-You can reverse at any time the behavior of `delete-by-moving-to-trash' by using
-a prefix arg with any of the delete files command.
-
-On GNULinux distribution, when navigating to a Trash directory you
-can restore any file in ..Trash/files directory with the 'Restore
-from trash' action you will find in action menu (needs the
-trash-cli package installed).
-You can as well delete files from Trash directories with the 'delete files from trash'
-action.
-
-Tip: Navigate to your Trash/files directories with `helm-find-files' and set a bookmark
-there with \\<helm-find-files-map>\\[helm-ff-bookmark-set] for fast access to Trash.
-
-_WARNING:_
-
-If you have an ENV var XDG_DATA_HOME in your .profile or .bash_profile
-and this var is set to something like $HOME/.local/share (like preconized)
-`move-file-to-trash' may try to create $HOME/.local/share/Trash (literally)
-and its subdirs in the directory where you are actually trying to trash files.
-because `move-file-to-trash' is interpreting XDG_DATA_HOME literally instead
-of evaling its value (with `substitute-in-file-name').
-
-***** Trashing remote files with tramp
-
-Trashing remote files (or local files with sudo method) is disabled by default
-because tramp is requiring the 'trash' command to be installed, if you want to
-trash your remote files, customize `helm-trash-remote-files'.
-The package on most GNU/Linux based distributions is trash-cli, it is available [[https://github.com/andreafrancia/trash-cli][here]].
-
-NOTE:
-When deleting your files with sudo method, your trashed files will not be listed
-with trash-list until you log in as root.

-(defun helm-read-file-name-help-message ()
- (let ((name (if helm-alive-p
- (assoc-default 'name (helm-get-current-source))
- "generic")))
- (format
- "* Helm `%s' read file name completion
-
-This is `%s' read file name completion that have been \"helmized\"
-because you have enabled [[Helm mode][helm-mode]]'.
-Don't confuse this with `helm-find-files' which is a native helm command,
-see [[Helm functions vs helmized Emacs functions]].
-
-** Tips
-
-*** Navigation
-
-**** Enter `~/' at end of pattern to quickly reach home directory
-
-**** Enter `/' at end of pattern to quickly reach the file system root
-
-**** Enter `./' at end of pattern to quickly reach `default-directory'
-
-\(As per its value at the beginning of the session.)
-
-If you already are in the `default-directory' this will move the cursor to the top.
-
-**** Enter `../' at end of pattern will reach upper directory, moving cursor on top
-
-This is different from using `\\[helm-find-files-up-one-level]' in that it moves
-the cursor to the top instead of remaining on the previous subdir name.
-
-**** You can complete with partial basename
-
-It starts from the third character of the pattern.
-
-For instance \"fob\" or \"fbr\" will complete \"foobar\" but \"fb\" needs a
-third character in order to complete it.
-
-*** Persistent actions
-
-By default `helm-read-file-name' uses the persistent actions of `helm-find-files'.
-
-**** Use `\\[universal-argument] \\<helm-map>\\[helm-execute-persistent-action]' to display an image
-
-**** `\\<helm-map>\\[helm-execute-persistent-action]' on a filename will expand to this filename in Helm-buffer
-
-Second hit displays the buffer filename.
-Third hit kills the buffer filename.
-Note: `\\[universal-argument] \\<helm-map>\\[helm-execute-persistent-action]' displays the buffer directly.
-
-**** Browse images directories with `helm-follow-mode' and navigate up/down
-
-*** Delete characters backward
-
-When you want to delete characters backward, e.g. to create a new file or directory,
-auto-update may come in the way when it keeps updating to an existent directory.
-In that case, type `C-<backspace>' and then `<backspace>'.
-This should not be needed when copying/renaming files because autoupdate is disabled
-by default in that case.
-
-Note: On a terminal, the default binding `C-<backspace>' may not work.
-In this case use `C-c <backspace>'.
-
-*** Create new directories and files
-
-**** You can create a new directory and a new file at the same time
-
-Simply write the path in prompt and press `RET', e.g.
-\"~/new/newnew/newnewnew/my_newfile.txt\".
-
-**** To create a new directory, append a \"/\" at to the new name and press `RET'
-
-**** To create a new file, enter a filename not ending with \"/\"
-
-File and directory creation works only with some commands (e.g. `find-file')
-and it will not work with others where it is not intended to return a file or
-a directory \(e.g `list-directory').
-
-*** Exiting minibuffer with empty string
-
-You can exit minibuffer with empty string with \\<helm-read-file--map>\\[helm-cr-empty-string].
-It is useful when some commands are prompting continuously until you enter an empty prompt.
-
-** Commands
-\\<helm-read-file-map>
-\\[helm-find-files-up-one-level]\t\tGo to parent directory.
-\\[helm-ff-run-toggle-auto-update]\t\tToggle auto-expansion of directories.

-C/\\[helm-cr-empty-string]\t\tReturn empty string unless `must-match' is non-nil.
-\\[helm-next-source]\t\tGo to next source.
-\\[helm-previous-source]\t\tGo to previous source."

-;;; Generic file help - Used by locate.

-;;
-(defvar helm-generic-file-help-message
- "* Helm Generic files
-
-** Tips
-
-*** Locate
-
-You can append to the search pattern any of the locate command line options,
-e.g. -b, -e, -n <number>, etc. See the locate(1) man page for more details.
-
-Some other sources (at the moment \"recentf\" and \"file in current directory\")
-support the -b flag for compatibility with locate when they are used with it.
-
-When you enable fuzzy matching on locate with `helm-locate-fuzzy-match', the
-search will be performed on basename only for efficiency (so don't add \"-b\" at
-prompt). As soon as you separate the patterns with spaces, fuzzy matching will
-be disabled and search will be done on the full filename. Note that in
-multi-match, fuzzy is completely disabled, which means that each pattern is a
-match regexp (i.e. \"helm\" will match \"helm\" but \"hlm\" will \*not* match
-\"helm\").
-
-*** Browse project
-
-When the current directory is not under version control, don't forget to refresh
-the cache when files have been added/removed in the directory.
-
-*** Find command
-
-Recursively search files using the \"find\" shell command.
-
-Candidates are all filenames that match all given globbing patterns. This
-respects the options `helm-case-fold-search' and
-`helm-findutils-search-full-path'.
-
-You can pass arbitrary \"find\" options directly after a \"*\" separator.
-For example, this would find all files matching \"book\" that are larger
-than 1 megabyte:
-
- book * -size +1M

-;;; Grep help

-;;
-(defvar helm-grep-help-message
- "* Helm Grep
-
-** Tips
-
-*** Use a prefix argument to grep recursively
-
-With Helm supporting git-grep and AG however, you are better off using one of
-them for recursive searches.
-
-*** You can use wild cards when selecting files (e.g. \"*.el\")
-
-*** You can grep in many different directories by marking files or using wild cards
-
-*** You can save the result in a `helm-grep-mode' buffer
-
-See [[Commands][commands]] below.
-
-Once in that buffer you can use \"emacs-wgrep\" (external package not bundled with Helm)
-to edit your changes.
-
-*** Helm-grep supports multi-matching
-
-\(Starting from version 1.9.4.)
-
-Simply add a space between each pattern as for most Helm commands.
-
-*** See full path of selected candidate
-
-Add (helm-popup-tip-mode 1) in your init file or enable it interactively with
-M-x helm-popup-tip-mode.
-
-*** Open file in other window
-
-The command \\<helm-grep-map>\\[helm-grep-run-other-window-action] allow you to open file
-in other window horizontally or vertically if a prefix arg is supplied.
-
-*** Performance over TRAMP
-
-Grepping works but it is badly supported as TRAMP doesn't support multiple
-processes running in a short delay (less than 5s) among other things.
-
-Helm uses a special hook to suspend the process automatically while you are
-typing. Even if Helm handles this automatically by delaying each process by 5s,
-you are adviced to this manually by hitting `\\<helm-map>\\[helm-toggle-suspend-update]' (suspend process) before
-typing, and hit again `\\<helm-map>\\[helm-toggle-suspend-update]' when the regexp is ready to send to the remote
-process. For simple regexps, there should be no need for this.
-
-Another solution is to not use TRAMP at all and mount your remote file system via
-SSHFS.
-
-* Helm GID
-
-** Tips
-
-Helm-GID reads the database created with the `mkid' command from id-utils.
-The name of the database file can be customized with `helm-gid-db-file-name', it
-is usually \"ID\".
-
-Helm-GID use the symbol at point as default-input. This command is also
-accessible from `helm-find-files' which allow you to navigate to another
-directory to consult its database.
-
-Note: Helm-GID supports multi-matches but only the last pattern entered will be
-highlighted since there is no ~--color~-like option in GID itself.
-
-* Helm AG
-
-** Tips
-
-Helm-AG is different from grep or ack-grep in that it works on a directory and
-not on a list of files.
-
-You can ignore files and directories with a \".agignore\" file, local to a
-directory or global when placed in the home directory. \(See the AG man page for
-more details.) That file follows the same syntax as `helm-grep-ignored-files'
-and `helm-grep-ignored-directories'.
-
-As always you can access Helm AG from `helm-find-files'.
-
-Starting with version 0.30, AG accepts one or more TYPE arguments on its command
-line. Helm provides completion on these TYPE arguments when available with your
-AG version. Use a prefix argument when starting a Helm-AG session to enable this
-completion.
-
-Note: You can mark several types to match in the AG query. The first AG
-versions providing this feature allowed only one type, so in this case only the
-last mark will be used.
-
-* Helm git-grep
-
-Helm-git-grep searches the current directory, i.e the default directory or the
-directory in Helm-find-files. If this current directory is a subdirectory of a
-project and you want to also match parent directories (i.e the whole project),
-use a prefix argument.

-(defvar helm-esh-help-message
- "* Helm Eshell on file
-
-** Tips
-
-*** Pass extra arguments after filename
-
-Normally the command or alias will be called with file as argument. For instance
-
- <command> candidate_file
-
-But you can also pass an argument or more after \"candidate_file\" like this:
-
- <command> %s [extra_args]
-
-\"candidate_file\" will be added at \"%s\" and the command will look at this:
-
- <command> candidate_file [extra_args]
-
-*** Specify marked files as arguments
-
-Example:
-
- <command> file1 file2...
-
-Call `helm-find-files-eshell-command-on-file' with one prefix argument. Otherwise
-you can pass one prefix argument from the command selection buffer.
-
-Note: This does not work on remote files.
-
-With two prefix-args the output is printed to the `current-buffer'.
-
-With no prefix argument or a prefix argument value of '(16) (`\\[universal-argument] \\[universal-argument]')
-the command is called once for each file like this:
-
- <command> file1
- <command> file2

-(defvar helm-moccur-help-message
- "* Helm Moccur
-
-** Tips
-
-*** Matching
-
-Multiple regexp matching is allowed, simply enter a space to separate the regexps.
-
-Matching empty lines is supported with the regexp \"^$\", you then get the
-results displayed as the buffer-name and the line number only. You can
-save and edit these results, i.e. add text to the empty line.
-
-*** Automatically match symbol at point
-
-Helm can automatically match the symbol at point while keeping the minibuffer
-empty, ready to be written to. This behaviour is disabled by default. To
-enable this you need to add `helm-source-occur' and `helm-source-moccur' to
-`helm-sources-using-default-as-input'.
-
-*** Jump to the corresponding line in the searched buffer
-
-You can do this with `\\<helm-map>\\[helm-execute-persistent-action]' (persistent-action), to do it repeatedly
-you can use `\\<helm-map>\\[helm-follow-action-forward]' and `\\<helm-map>\\[helm-follow-action-backward]' or enable `helm-follow-mode' with `\\<helm-map>\\[helm-follow-mode]'.
-
-*** Switch to buffer in other window
-
-The command \\<helm-moccur-map>\\[helm-moccur-run-goto-line-ow] allow you to switch to buffer
-in other window horizontally or vertically if a prefix arg is supplied.
-
-*** Save the results
-
-Similarly to Helm-grep, you can save the results with `\\<helm-map>\\[helm-moccur-run-save-buffer]'.
-Once in the saved buffer, you can edit it, see [[Edit a saved buffer][below]].
-
-Of course if you don't save the results, you can resume the Helm session with
-`helm-resume'.
-
-*** Refresh the resumed session
-
-When the buffer(s) where you ran helm-(m)occur get(s) modified, the Helm buffer
-will flash red as a warning. You can refresh the buffer by running `\\<helm-map>\\[helm-refresh]'.
-This can be done automatically by customizing `helm-moccur-auto-update-on-resume'.
-
-*** Refresh a saved buffer
-
-Type `g' to update the buffer.
-
-*** Edit a saved buffer
-
-First, install wgrep (https://github.com/mhayashi1120/Emacs-wgrep) and then:
-
-1) `C-c C-p' (`wgrep-change-to-wgrep-mode') to edit the buffer(s).
-2) `C-x C-s' to save your changes.
-
-Tip: Use the excellent iedit (https://github.com/victorhge/iedit) to modify all
-occurences at once in the buffer.
-
-*** Search in region
-
-When searching in current-buffer with `helm-occur', if a region
-is found helm will search in this region only. If you marked
-this region with `mark-defun' the symbol that was at point before
-marking defun will be used when `helm-source-occur' is member of
-`helm-sources-using-default-as-input'.
-
-** Commands
-\\<helm-moccur-map>
-\\[helm-goto-next-file]\t\tNext buffer.

-(defvar helm-el-package-help-message
- "* Helm Elisp package
-
-** Tips
-
-*** Compile all your packages asynchronously
-
-If you use async (if you have installed Helm from MELPA you do), only \"helm\",
-\"helm-core\", and \"magit\" are compiled asynchronously. If you want all your
-packages compiled asynchronously, add this to your init file:
-
- (setq async-bytecomp-allowed-packages '(all))
-
-*** Upgrade Elisp packages
-
-On initialization (when Emacs is fetching packages on remote), if Helm finds
-packages to upgrade, it will start in the upgradable packages view showing the packages
-available for upgrade.
-
-On subsequent runs, you will have to refresh the list with `C-c \\[universal-argument]'. If Helm
-finds upgrades you can switch to upgrade view (see below) to see what packages
-are available for upgrade or simply hit `C-c U' to upgrade them all.
-
-To see upgradable packages hit `M-U'.
-
-Then you can install all upgradable packages with the \"upgrade all\" action
-\(`C-c \\[universal-argument]'), or upgrade only specific packages by marking them and running the
-\"upgrade\" action (visible only when there are upgradable packages). Of course
-you can upgrade a single package by just running the \"upgrade\" action without
-marking it (`C-c u' or `RET') .
-
-\*Warning:* You are strongly advised to \*restart* Emacs after \*upgrading* packages.
-
-*** Meaning of flags prefixing packages
-
-\(Emacs ≥25)
-
-- The flag \"S\" that prefixes package names means that the packages belong to `package-selected-packages'.
-
-- The flag \"U\" that prefix package names mean that this package is no more needed.

-(defvar helm-kill-ring-help-message
- "* Helm kill ring
-
-** Tips
-
-Every Helm session lets you save a candidate to the kill-ring / clipboard /
-primary-selection with `\\<helm-map>\\[helm-kill-selection-and-quit]'.
-
-To save space, Helm-kill-ring truncates the candidates longer than
-`helm-kill-ring-max-offset'.
-`\\<helm-kill-ring-map>\\[helm-kill-ring-kill-selection]' then saves the whole
-text and not the truncated value. The view of truncated candidates can be
-toggled; see the command list below.
-
-As opposed to `yank', numeric prefix arguments are ignored with
-`helm-show-kill-ring': there is no need for them since selection happens within
-Helm. Moreover Helm has [[Shortcuts for executing Default Action on the nth
-candidate][Shortcuts for executing Default Action on the nth candidate]].
-
-It is recommended to globally bind `M-y' to `helm-show-kill-ring'. Once in the
-Helm-kill-ring session you can navigate to next/previous line with `M-y' and
-`M-u' for convenience. Of course `\\[helm-next-line]' and `\\[helm-previous-line]' are still available.
-
-It is possible to delete candidates from the kill ring.
-
-You can concatenate marked candidates and yank them in the current
-buffer, thus creating a new entry in the kill ring. Candidates are
-concatenated with `helm-kill-ring-separator' as default but you can
-change interactively the separator while yanking by using two prefix
-args. When you have something else than \"\\n\" as default value for
-`helm-kill-ring-separator' and you want to use \"\\n\" from prompt, use
-`C-q C-j' to enter a newline in prompt.
-
-To not push a new entry in the kill ring, use `\\<helm-map>\\[helm-copy-to-buffer]' instead of RET
-\(note that you can't change separator with this).
-
-When inserting candidates with the default action (`RET'), `point' is placed at
-the end of the candidate and `mark' at the beginning. You can revert this behavior
-by using a prefix argument, i.e. `C-u RET', like the regular `yank' command does.
-
-** Commands
-\\<helm-kill-ring-map>
-\\[helm-next-line]\t\tNext line.
-\\[helm-previous-line]\t\tPrevious line.

-*** Tags completion
-

-look at its docstring.
-
-**** Single tag
-
-From an org heading hit C-c C-c which provide a

-existing tag or write a new tag in prompt. At this point you end
-up with an entry in your prompt, if you enter RET, the entry is
-added as tag in your org header.
-
-**** Multiple tags
-
-If you want to add more tag to your org header, add a separator[1] after
-your tag and write a new tag or hit TAB to find another existing
-tag, and so on until you have all the tags you want
-e.g \"foo,bar,baz\" then press RET to finally add the tags to your

- "Completing read functions for specific Emacs commands.
-
-By default `helm-mode' use `helm-completing-read-default-handler' to
-provide helm completion in each `completing-read' or `read-file-name'
-found, but other functions can be specified here for specific
-commands. This also allow disabling helm completion for some commands
-when needed.
-
-Each entry is a cons cell like (EMACS_COMMAND . COMPLETING-READ_HANDLER)
-where key and value are symbols.
-
-Each key is an Emacs command that use originaly `completing-read'.
-
-Each value maybe a helm function that takes same arguments as
-`completing-read' plus NAME and BUFFER, where NAME is the name of the new
-helm source and BUFFER the name of the buffer we will use, but it can
-be also a function not using helm, in this case the function should
-take same args as `completing-read' and not be prefixed by \"helm-\".
-
-`helm' will use the name of the command calling `completing-read' as
-NAME and BUFFER will be computed as well with NAME but prefixed with
-\"*helm-mode-\".
-
-This function prefix name must start by \"helm-\" when it uses helm,
-otherwise `helm' assumes the function is not a helm function and
-expects same args as `completing-read', this allow you to define a
-handler not using helm completion.
-
-Example:
-
- (defun foo/test ()
- (interactive)
- (message \"%S\" (completing-read \"test: \" '(a b c d e))))
-
- (defun helm-foo/test-completing-read-handler (prompt collection
- predicate require-match
- initial-input hist def
- inherit-input-method
- name buffer)
- (helm-comp-read prompt collection :marked-candidates t
- :name name
- :buffer buffer))
-
- (add-to-list 'helm-completing-read-handlers-alist
- '(foo/test . helm-foo/test-completing-read-handler))
-
-
-We want here to make the regular `completing-read' in `foo/test'
-returns a list of candidate(s) instead of a single candidate.
-
-Note that this function will be reused for ALL the `completing-read'
-of this command, so it should handle all cases, e.g
-If first `completing-read' complete against symbols and
-second `completing-read' should handle only buffer,
-your specialized function should handle the both.
-
-If the value of an entry is nil completion will fall back to
-emacs vanilla behavior.
-Example:
-
-If you want to disable helm completion for `describe-function', use:
-
- (describe-function . nil)
-
-Ido is also supported, you can use `ido-completing-read' and
-`ido-read-file-name' as value of an entry or just 'ido.
-Example:
-Enable ido completion for `find-file':
-
- (find-file . ido)
-
-same as
-
- (find-file . ido-read-file-name)
-

- to non--nil. (possibles values are t or nil).
-
-- VOLATILE: Use volatile attribute.
-
-- SORT: A predicate to give to `sort' e.g `string-lessp'
- Use this only on small data as it is ineficient.
- If you want to sort faster add a sort function to
- FC-TRANSFORMER.
- Note that FUZZY when enabled is already providing a sort function.
-
-- FC-TRANSFORMER: A `filtered-candidate-transformer' function
- or a list of functions.
-
-- HIST-FC-TRANSFORMER: A `filtered-candidate-transformer'
- function for the history source.
-
-- MARKED-CANDIDATES: If non--nil return candidate or marked candidates as a list.
-
-- NOMARK: When non--nil don't allow marking candidates.
-
-- ALISTP: \(default is non--nil\) See `helm-comp-read-get-candidates'.
-
-- CANDIDATES-IN-BUFFER: when non--nil use a source build with
- `helm-source-in-buffer' which is much faster.
- Argument VOLATILE have no effect when CANDIDATES-IN-BUFFER is non--nil.
-
-- MATCH-PART: Allow matching only one part of candidate.
- See match-part documentation in `helm-source'.
-
-- ALLOW-NEST: Allow nesting this `helm-comp-read' in a helm session.
- See `helm'.
-
-- MULTILINE: See multiline in `helm-source'.

+ ack-grep --type option. (Not mandatory)
+
+'%c' format spec is for case-fold-search,
+ whether to use the -i option of grep. (Not mandatory)
+ When you specify this spec, helm grep will use smartcase
+ that is when a upcase character is found in pattern case will
+ be respected and no '-i' option will be used, otherwise, when
+ no upcase character is found in pattern always use '-i'.
+ If you don't want this behavior, don't use this spec and
+ specify or not the '-i' option.
+ Note that with ack-grep this is not needed, just specify
+ the '--smart-case' option.
+
+'%p' format spec is for pattern. (Mandatory)
+
+'%f' format spec is for filenames. (Mandatory)
+
+If your grep version doesn't support the --exclude/include args
+don't specify the '%e' format spec.
+
+Helm also support ack-grep and git-grep ,
+here a default command example for ack-grep:
+
+\(setq helm-grep-default-command \"ack-grep -Hn --color --smart-case --no-group %e %p %f\"
+ helm-grep-default-recurse-command \"ack-grep -H --color --smart-case --no-group %e %p %f\")
+
+You can ommit the %e spec if you don't want to be prompted for types.
+
+NOTE: Helm for ack-grep support ANSI sequences, so you can remove
+the \"--no-color\" option safely (recommended)
+However you should specify --color to enable multi matches highlighting
+because ack disable it when output is piped.
+
+Same for grep you can use safely the option \"--color=always\" (default).
+You can customize the color of matches using GREP_COLORS env var.
+e.g: \(setenv \"GREP_COLORS\" \"ms=30;43:mc=30;43:sl=01;37:cx=:fn=35:ln=32:bn=32:se=36\")
+
+To enable ANSI color in git-grep just add \"--color=always\".
+To customize the ANSI color in git-grep, GREP_COLORS have no effect,
+you will have to setup this in your .gitconfig:
+
+ [color \"grep\"]
+ match = black yellow
+
+where \"black\" is the foreground and \"yellow\" the background.
+See the git documentation for more infos.
+
+`helm-grep-default-command' and `helm-grep-default-recurse-command'are
+independents, so you can enable `helm-grep-default-command' with ack-grep
+and `helm-grep-default-recurse-command' with grep if you want to be faster
+on recursive grep.
+

+For ripgrep here is the command line to use:

+You must use an output format that fit with helm grep, that is:

+
+The option \"--nogroup\" allow this.
+The option \"--line-numbers\" is also mandatory except with PT (not supported).
+For RG the options \"--no-heading\" and \"--line-number\" are the ones to use.

+ "* Helm Buffer
+
+** Tips
+
+*** Completion
+
+**** Major-mode
+
+You can enter a partial major-mode name (e.g. lisp, sh) to narrow down buffers.
+To specify the major-mode, prefix it with \"*\" e.g. \"*lisp\".
+
+If you want to match all buffers but the ones with a specific major-mode
+\(negation), prefix the major-mode with \"!\" e.g. \"*!lisp\".
+
+If you want to specify more than one major-mode, separate them with \",\",
+e.g. \"*!lisp,!sh,!fun\" lists all buffers but the ones in lisp-mode, sh-mode
+and fundamental-mode.
+
+Then enter a space followed by a pattern to narrow down to buffers matching this
+pattern.
+
+**** Search inside buffers
+
+If you enter a space and a pattern prefixed by \"@\", Helm searches for text
+matching this pattern \*inside* the buffer (i.e. not in the name of the buffer).
+
+If you enter a pattern prefixed with an escaped \"@\", Helm searches for a
+buffer matching \"@pattern\" but does not search inside.
+
+**** Search by directory name
+
+If you prefix the pattern with \"/\", Helm matches over the directory names
+of the buffers.
+
+This feature can be used to narrow down the search to one directory while
+subsequent strings entered after a space match over the buffer name only.
+
+Note that negation is not supported for matching on buffer filename.
+
+Starting from Helm v1.6.8, you can specify more than one directory.
+
+**** Fuzzy matching
+
+`helm-buffers-fuzzy-matching' turns on fuzzy matching on buffer names, but not
+on directory names or major modes. A pattern starting with \"^\" disables fuzzy
+matching and matches by exact regexp.
+
+**** Examples
+
+With the following pattern
+
+ \"*lisp ^helm @moc\"
+
+Helm narrows down the list by selecting only the buffers that are in lisp mode,
+start with \"helm\" and which content matches \"moc\".
+
+Without the \"@\"
+
+ \"*lisp ^helm moc\"
+
+Helm looks for lisp mode buffers starting with \"helm\" and containing \"moc\"
+in their name.
+
+With this other pattern
+
+ \"*!lisp !helm\"
+
+Helm narrows down to buffers that are not in \"lisp\" mode and that do not match
+\"helm\".
+
+With this last pattern
+
+ /helm/ w3
+
+Helm narrows down to buffers that are in any \"helm\" subdirectory and
+matching \"w3\".
+
+*** Creating buffers
+
+When creating a new buffer, use `\\[universal-argument]' to choose a mode from a
+list. This list is customizable, see `helm-buffers-favorite-modes'.
+
+*** Killing buffers
+
+You can kill buffers either one by one or all the marked buffers at once.
+
+One kill-buffer command leaves Helm while the other is persistent. Run the
+persistent kill-buffer command either with the regular
+`helm-execute-persistent-action' called with a prefix argument (`\\[universal-argument] \\<helm-map>\\[helm-execute-persistent-action]')
+or with its specific command `helm-buffer-run-kill-persistent'. See the
+bindings below.
+
+*** Switching to buffers
+
+To switch to a buffer, press RET, to switch to a buffer in another window, select this buffer
+and press \\<helm-buffer-map>\\[helm-buffer-switch-other-window], when called with a prefix arg
+the buffer will be displayed vertically in other window.
+If you mark more than one buffer, the marked buffers will be displayed in different windows.
+
+*** Saving buffers
+
+If buffer is associated to a file and is modified, it is by default colorized in orange,
+see [[Meaning of colors and prefixes for buffers][Meaning of colors and prefixes for buffers]].
+You can save these buffers with \\<helm-buffer-map>\\[helm-buffer-save-persistent].
+If you want to save all these buffers, you can mark them with \\[helm-buffers-mark-similar-buffers]
+and save them with \\[helm-buffer-save-persistent], you can also do this in one step with
+\\[helm-buffer-run-save-some-buffers], note that you will not be asked for confirmation.
+
+*** Meaning of colors and prefixes for buffers
+
+Remote buffers are prefixed with '@'.
+Red => Buffer's file was modified on disk by an external process.
+Indianred2 => Buffer exists but its file has been deleted.
+Orange => Buffer is modified and not saved to disk.
+Italic => A non-file buffer.
+Yellow => Tramp archive buffer.
+
+** Commands
+\\<helm-buffer-map>

+(defvar helm-ff-help-message
+ "* Helm Find Files
+
+** Tips
+
+*** Navigation summary
+
+For a better experience you can enable auto completion by setting
+`helm-ff-auto-update-initial-value' to non-nil in your init file. It is not
+enabled by default to not confuse new users.
+
+**** Navigate with arrow keys
+
+You can use <right> and <left> arrows to go down or up one level, to enable
+this customize `helm-ff-lynx-style-map'.
+This is disabled by default.
+Note that using `setq' will NOT work.
+
+**** Use `\\<helm-find-files-map>\\[helm-execute-persistent-action]' (persistent action) on a directory to go down one level
+
+On a symlinked directory a prefix argument expands to its true name.
+
+**** Use `\\<helm-find-files-map>\\[helm-find-files-up-one-level]' or `DEL' on a directory to go up one level
+
+***** `DEL' behavior
+
+`DEL' by default is deleting char backward.
+
+But when `helm-ff-DEL-up-one-level-maybe' is non nil `DEL' behave
+differently depending of helm-pattern contents, it go up one
+level if pattern is a directory endings with \"/\" or disable HFF
+auto update and delete char backward if pattern is a filename or
+refer to a non existing path. Going up one level can be disabled
+if necessary by deleting \"/\" at end of pattern using
+\\<helm-map>\\[backward-char] and \\[helm-delete-minibuffer-contents].
+
+Note that when deleting char backward, helm takes care of
+disabling update letting you the time to edit your pattern for
+e.g. renaming a file or creating a new file or directory.
+When `helm-ff-auto-update-initial-value' is non nil you may want to
+disable it temporarily, see [[Toggle auto-completion with `C-c DEL'][Toggle auto-completion with `C-c DEL']] for this.
+
+**** Use `\\<helm-find-files-map>\\[helm-find-files-down-last-level]' to walk back the resulting tree of all the `\\<helm-find-files-map>\\[helm-find-files-up-one-level]' or DEL you did
+
+The tree is reinitialized each time you browse a new tree with
+`\\<helm-map>\\[helm-execute-persistent-action]' or by entering some pattern in the prompt.
+
+**** `RET' behavior
+
+It behaves differently depending on `helm-selection' (current candidate in helm-buffer):
+
+- candidate basename is \".\" => Open it in dired.
+- candidate is a directory => Expand it.
+- candidate is a file => Open it.
+
+If you have marked candidates and you press RET on a directory,
+helm will navigate to this directory, if you want to exit with
+RET with default action with these marked candidates, press RET
+on a second time while you are on the root of this directory
+e.g. \"/home/you/dir/.\" or press RET on any file which is not a
+directory. You can also exit with default action at any moment
+with `f1'.
+
+Note that when copying, renaming, etc. from `helm-find-files' the
+destination file is selected with `helm-read-file-name'.
+
+To avoid confusion when using `read-file-name' or `read-directory-name', `RET'
+follows its standard Emacs behaviour, i.e. it exits the minibuffer as soon as
+you press `RET'. If you want the same behavior as in `helm-find-files', bind
+`helm-ff-RET' to the `helm-read-file-map':
+
+ (define-key helm-read-file-map (kbd \"RET\") 'helm-ff-RET)
+
+**** `TAB' behavior
+
+Normally `TAB' is bound to `helm-select-action' in helm-map which
+display the action menu.
+
+You can change this behavior by setting in `helm-find-files-map'
+a new command for `TAB':
+
+ (define-key helm-find-files-map (kbd \"C-i\") 'helm-ff-TAB)
+
+It will then behave slighly differently
+depending of `helm-selection':
+
+- candidate basename is \".\" => open the action menu.
+- candidate is a directory => expand it (behave as \\<helm-map>\\[helm-execute-persistent-action]).
+- candidate is a file => open action menu.
+
+Called with a prefix arg open menu unconditionally.
+
+*** Find file at point
+
+Helm uses `ffap' partially or completely to find file at point depending on the
+value of `helm-ff-guess-ffap-filenames': if non-nil, support is complete
+\(annoying), if nil, support is partial.
+
+Note that when the variable
+`helm-ff-allow-non-existing-file-at-point' is non nil Helm will
+insert the filename at point even if file with this name doesn't
+exists. If non existing file at point ends with numbers prefixed
+with \":\" the \":\" and numbers are stripped.
+
+**** Find file at line number
+
+When text at point is in the form of
+
+ ~/elisp/helm/helm.el:1234
+
+Helm finds this file at the indicated line number, here 1234.
+
+**** Find URL at point
+
+When a URL is found at point, Helm expands to that URL only.
+Pressing `RET' opens that URL using `browse-url-browser-function'.
+
+**** Find e-mail address at point
+
+When an e-mail address is found at point, Helm expands to this e-mail address
+prefixed with \"mailto:\". Pressing `RET' opens a message buffer with that
+e-mail address.
+
+*** Quick pattern expansion
+
+**** Enter `~/' at end of pattern to quickly reach home directory
+
+**** Enter `/' at end of pattern to quickly reach the file system root
+
+**** Enter `./' at end of pattern to quickly reach `default-directory'
+
+\(As per its value at the beginning of the session.)
+
+If you already are in the `default-directory' this will move the cursor to the top.
+
+**** Enter `../' at end of pattern will reach upper directory, moving cursor to the top
+
+This is different from using `\\<helm-find-files-map>\\[helm-find-files-up-one-level]' in that it moves
+the cursor to the top instead of remaining on the previous subdir name.
+
+**** Enter `..name/' at end of pattern to start a recursive search
+
+It searches directories matching \"name\" under the current directory, see the
+\"Recursive completion on subdirectories\" section below for more details.
+
+**** Any environment variable (e.g. `$HOME') at end of pattern gets expanded
+
+**** Any valid filename yanked after pattern gets expanded
+
+**** Special case: URL at point
+
+The quick expansions do not take effect after end a URL, you must kill the
+pattern first (`\\[helm-delete-minibuffer-contents]').
+
+*** Helm-find-files supports fuzzy matching
+
+It starts from the third character of the pattern.
+
+For instance \"fob\" or \"fbr\" will complete \"foobar\" but \"fb\" needs a
+third character in order to complete it.
+
+*** Use `\\[universal-argument] \\[helm-execute-persistent-action]' or `\\[helm-follow-action-forward]' to display an image
+
+*** `\\[helm-execute-persistent-action]' on a filename expands to that filename in the Helm buffer
+
+Second hit displays the buffer filename.
+Third hit kills the buffer filename.
+Note: `\\[universal-argument] \\[helm-execute-persistent-action]' displays the buffer directly.
+
+*** Browse images directories with `helm-follow-mode' and navigate up/down
+
+You can also use `helm-follow-action-forward' and `helm-follow-action-backward' with
+`\\[helm-follow-action-forward]' and `\\[helm-follow-action-backward]' respectively.
+
+*** Toggle auto-completion with `\\[helm-ff-run-toggle-auto-update]'
+
+It is useful when trying to create a new file or directory and you don't want
+Helm to complete what you are writing.
+
+Note: On a terminal, the default binding `C-<backspace>' may not work.
+In this case use `C-c <backspace>'.
+
+*** You can create a new directory and a new file at the same time
+
+Simply write the path in the prompt and press `RET', e.g.
+\"~/new/newnew/newnewnew/my_newfile.txt\".
+
+*** To create a new directory, append a \"/\" to the new name and press `RET'
+
+*** To create a new file, enter a filename not ending with \"/\"
+
+Note that when you enter a new name, this one is prefixed with
+\[?] if you are in a writable directory. If you are in a directory
+where you have no write permission the new file name is not
+prefixed and is colored in red. There is not such distinction
+when using tramp, new filename just appear on top of buffer.
+
+*** Recursive search from Helm-find-files
+
+**** You can use Helm-browse-project (see binding below)
+
+- With no prefix argument:
+If the current directory is under version control with either git or hg and
+helm-ls-git and/or helm-ls-hg are installed, it lists all the files under
+version control. Otherwise it falls back to Helm-find-files. See
+https://github.com/emacs-helm/helm-ls-git and
+https://github.com/emacs-helm/helm-ls-hg.
+
+- With one prefix argument:
+List all the files under this directory and other subdirectories
+\(recursion) and this list of files will be cached.
+
+- With two prefix arguments:
+Same but the cache is refreshed.
+
+**** You can start a recursive search with \"locate\" or \"find\"
+
+See \"Note\" in the [[Recursive completion on subdirectories][section on subdirectories]].
+
+Using \"locate\", you can enable the local database with a prefix argument. If the
+local database doesn't already exists, you will be prompted for its creation.
+If it exists and you want to refresh it, give it two prefix args.
+
+When using locate the helm-buffer remains empty until you type something.
+Regardless Helm uses the basename of the pattern entered in the helm-find-files
+session by default. Hitting `\\[next-history-element]' should just kick in the
+locate search with this pattern. If you want Helm to automatically do this, add
+`helm-source-locate' to `helm-sources-using-default-as-input'.
+
+**** Recursive completion on subdirectories
+
+Starting from the directory you are currently browsing, it is possible to have
+completion of all directories underneath. Say you are at \"/home/you/foo/\" and
+you want to go to \"/home/you/foo/bar/baz/somewhere/else\", simply type
+\"/home/you/foo/..else\" and hit `\\[helm-execute-persistent-action]' or enter
+the final \"/\". Helm will then list all possible directories under \"foo\"
+matching \"else\".
+
+Entering two spaces before \"else\" instead of two dots also works.
+
+Note: Completion on subdirectories uses \"locate\" as backend, you can configure
+the command with `helm-locate-recursive-dirs-command'. Because this completion
+uses an index, the directory tree displayed may be out-of-date and not reflect
+the latest change until you update the index (using \"updatedb\" for \"locate\").
+
+If for some reason you cannot use an index, the \"find\" command from
+\"findutils\" can be used instead. It will be slower though. You need to pass
+the basedir as first argument of \"find\" and the subdir as the value for
+'-(i)regex' or '-(i)name' with the two format specs that are mandatory in
+`helm-locate-recursive-dirs-command'.
+
+Examples:
+- \"find %s -type d -name '*%s*'\"
+- \"find %s -type d -regex .*%s.*$\"
+
+*** Insert filename at point or complete filename at point
+
+On insertion (not on completion, i.e. there is nothing at point):
+
+- `\\[helm-ff-run-complete-fn-at-point]': insert absolute file name.
+- `\\[universal-argument] \\[helm-ff-run-complete-fn-at-point]': insert abbreviated file name.
+- `\\[universal-argument] \\[universal-argument] \\[helm-ff-run-complete-fn-at-point]': insert relative file name.
+- `\\[universal-argument] \\[universal-argument] \\[universal-argument] \\[helm-ff-run-complete-fn-at-point]': insert basename.
+
+On completion:
+
+- Target starts with \"~/\": insert abbreviate file name.
+- target starts with \"/\" or \"[a-z]:/\": insert full path.
+- Otherwise: insert relative file name.
+
+*** Use the wildcard to select multiple files
+
+Use of wilcard is supported to run an action over a set of files.
+
+Example: You can copy all the files with \".el\" extension by using \"*.el\" and
+then run copy action.
+
+Similarly, \"**.el\" (note the two stars) will recursively select all \".el\"
+files under the current directory.
+
+Note that when recursively copying files, you may have files with same name
+dispatched across different subdirectories, so when copying them in the same
+directory they will get overwritten. To avoid this Helm has a special action
+called \"backup files\" that has the same behavior as the command line \"cp -f
+--backup=numbered\": it allows you to copy many files with the same name from
+different subdirectories into one directory. Files with same name are renamed
+as follows: \"foo.txt.~1~\". Like with the --force option of cp, it is possible
+to backup files in current directory.
+
+This command is available only when `dired-async-mode' is active.
+
+When using an action that involves an external backend (e.g. grep), using \"**\"
+is not recommended (even thought it works fine) because it will be slower to
+select all the files. You are better off leaving the backend to do it, it will
+be faster. However, if you know you have not many files it is reasonable to use
+this, also using not recursive wilcard (e.g. \"*.el\") is perfectly fine for
+this.
+
+The \"**\" feature is active by default in the option `helm-file-globstar'. It
+is different from the Bash \"shopt globstar\" feature in that to list files with
+a named extension recursively you would write \"**.el\" whereas in Bash it would
+be \"**/*.el\". Directory selection with \"**/\" like Bash \"shopt globstar\"
+option is not supported yet.
+
+*** Query replace regexp on filenames
+
+Replace different parts of a file basename with something else.
+
+When calling this action you will be prompted twice as with
+`query-replace', first for the matching expression of the text to
+replace and second for the replacement text. Several facilities,
+however, are provided to make the two prompts more powerfull.
+
+**** Syntax of the first prompt
+
+In addition to simple regexps, these shortcuts are available:
+
+- Basename without extension => \"%.\"
+- Only extension => \".%\"
+- Substring => \"%:<from>:<to>\"
+- Whole basename => \"%\"
+
+**** Syntax of the second prompt
+
+In addition to a simple string to use as replacement, here is what you can use:
+
+- A placeholder refering to what you have selected in the first prompt: \"\\@\".
+
+After this placeholder you can use a search-and-replace syntax à-la sed:
+
+ \"\\@/<regexp>/<replacement>/
+
+You can select a substring from the string represented by the placeholder:
+
+ \"\\@:<from>:<to>\"
+
+- A special character representing a number which is incremented: \"\\#\".
+
+- Shortcuts for `upcase', `downcase' and `capitalize'
+are available as`%u', `%d' and `%c' respectively.
+
+**** Examples
+
+***** Recursively rename all files with \".JPG\" extension to \".jpg\"
+
+Use the `helm-file-globstar' feature described in [[Use the wildcard to select multiple files][recursive globbing]]
+by entering \"**.JPG\" at the end of the Helm-find-files pattern, then hit
+\\<helm-map>\\[helm-ff-query-replace-on-filenames]: First \"JPG\", then \"jpg\"
+and hit `RET'.
+
+Alternatively you can enter \".%\" at the first prompt, then \"jpg\" and hit
+`RET'. Note that when using this instead of using \"JPG\" at the first prompt,
+all extensions will be renamed to \"jpg\" even if the extension of one of the
+files is, say, \"png\". If you want to keep the original extension you can use
+\"%d\" at the second prompt (downcase).
+
+***** Batch-rename files from number 001 to 00x
+
+Use \"\\#\" inside the second prompt.
+
+Example 1: To rename the files
+
+ foo.jpg
+ bar.jpg
+ baz.jpg
+
+to
+
+ foo-001.jpg
+ foo-002.jpg
+ foo-003.jpg
+
+use \"%.\" as matching regexp and \"foo-\\#\" as replacement string.
+
+Example 2: To rename the files
+
+ foo.jpg
+ bar.jpg
+ baz.jpg
+
+to
+
+ foo-001.jpg
+ bar-002.jpg
+ baz-003.jpg
+
+use as matching regexp \"%.\" and as replacement string \"\\@-\\#\".
+
+***** Replace a substring
+
+Use \"%:<from>:<to>\".
+
+Example: To rename files
+
+ foo.jpg
+ bar.jpg
+ baz.jpg
+
+to
+
+ fOo.jpg
+ bAr.jpg
+ bAz.jpg
+
+use as matching regexp \"%:1:2\" and as replacement string \"%u\" (upcase).
+
+Note that you \*cannot* use \"%.\" and \".%\" along with substring replacement.
+
+***** Modify the string from the placeholder (\\@)
+
+- By substring, i.e. only using the substring of the placeholder: \"\\@:<from>:<to>\".
+The length of placeholder is used for <to> when unspecified.
+
+Example 1: \"\\@:0:2\" replaces from the beginning to the second char of the placeholder.
+
+Example 2: \\@:2: replaces from the second char of the placeholder to the end.
+
+- By search-and-replace: \"\\@/<regexp>/<replacement>/\".
+
+Incremental replacement is also handled in <replacement>.
+
+Example 3: \"\\@/foo/bar/\" replaces \"foo\" by \"bar\" in the placeholder.
+
+Example 4: \"\\@/foo/-\\#/\" replaces \"foo\" in the placeholder by 001, 002, etc.
+
+***** Clash in replacements (avoid overwriting files)
+
+When performing any of these replacement operations you may end up with same
+names as replacement. In such cases Helm numbers the file that would otherwise
+overwritten. For instance, should you remove the \"-m<n>\" part from the files
+\"emacs-m1.txt\", \"emacs-m2.txt\" and \"emacs-m3.txt\" you would end up with
+three files named \"emacs.txt\", the second renaming overwriting first file, and
+the third renaming overwriting second file and so on. Instead Helm will
+automatically rename the second and third files as \"emacs(1).txt\" and
+\"emacs(2).txt\" respectively.
+
+***** Query-replace on filenames vs. serial-rename action
+
+Unlike the [[Serial renaming][serial rename]] actions, the files renamed with
+the query-replace action stay in their initial directory and are not moved to
+the current directory. As such, using \"\\#\" to serial-rename files only makes
+sense for files inside the same directory. It even keeps renaming files
+with an incremental number in the next directories.
+
+*** Serial renaming
+
+You can use the serial-rename actions to rename, copy or symlink marked files to
+a specific directory or in the current directory with all the files numbered
+incrementally.
+
+- Serial-rename by renaming:
+Rename all marked files with incremental numbering to a specific directory.
+
+- Serial-rename by copying:
+Copy all marked files with incremental numbering to a specific directory.
+
+- Serial-rename by symlinking:
+Symlink all marked files with incremental numbering to a specific directory.
+
+*** Edit marked files in a dired buffer
+
+You can open a dired buffer containing only marked files with `\\<helm-find-files-map>\\[helm-ff-run-marked-files-in-dired]'.
+With a prefix argument you can open this same dired buffer in wdired mode for
+editing. Note that wildcards are supported as well, so you can use e.g.
+\"*.txt\" to select all \".txt\" files in the current directory or \"**.txt\" to
+select all files recursively from the current directory.
+See [[Use the wildcard to select multiple files]] section above.
+
+*** Defining default target directory for copying, renaming, etc
+
+You can customize `helm-dwim-target' to behave differently depending on the
+windows open in the current frame. Default is to provide completion on all
+directories associated to each window.
+
+*** Copying and renaming asynchronously
+
+If you have the async library installed (if you got Helm from MELPA you do), you
+can use it for copying/renaming files by enabling `dired-async-mode'.
+
+Note that even when async is enabled, running a copy/rename action with a prefix
+argument will execute action synchronously. Moreover it will follow the first
+file of the marked files in its destination directory.
+
+When `dired-async-mode' is enabled, an additional action named \"Backup files\"
+will be available. (Such command is not natively available in Emacs).
+See [[Use the wildcard to select multiple files]] for details.
+
+*** Bookmark the `helm-find-files' session
+
+You can bookmark the `helm-find-files' session with `\\[helm-ff-bookmark-set]'.
+You can later retrieve these bookmarks by calling `helm-filtered-bookmarks'
+or, from the current `helm-find-files' session, by hitting `\\[helm-find-files-toggle-to-bookmark]'.
+
+*** Grep files from `helm-find-files'
+
+You can grep individual files from `helm-find-files' by using
+\`\\<helm-find-files-map>\\[helm-ff-run-grep]'. This same command can also
+recursively grep files from the current directory when called with a prefix
+argument. In this case you will be prompted for the file extensions to use
+\(grep backend) or the types of files to use (ack-grep backend). See the
+`helm-grep-default-command' documentation to set this up. For compressed files
+or archives, use zgrep with \`\\<helm-find-files-map>\\[helm-ff-run-zgrep]'.
+
+Otherwise you can use recursive commands like \`\\<helm-find-files-map>\\[helm-ff-run-grep-ag]' or `\\<helm-find-files-map>\\[helm-ff-run-git-grep]'
+that are much faster than using `\\<helm-find-files-map>\\[helm-ff-run-grep]' with a prefix argument.
+See `helm-grep-ag-command' and `helm-grep-git-grep-command' to set this up.
+
+You can also use \"id-utils\"' GID with \`\\<helm-find-files-map>\\[helm-ff-run-gid]'
+by creating an ID index file with the \"mkid\" shell command.
+
+All those grep commands use the symbol at point as the default pattern.
+Note that default is different from input (nothing is added to the prompt until
+you hit `\\[next-history-element]').
+
+**** Grepping on remote files
+
+On remote files grep is not well supported by TRAMP unless you suspend updates before
+entering the pattern and re-enable it once your pattern is ready.
+To toggle suspend-update, use `\\<helm-map>\\[helm-toggle-suspend-update]'.
+
+*** Execute Eshell commands on files
+
+Setting up aliases in Eshell allows you to set up powerful customized commands.
+
+Adding Eshell aliases to your `eshell-aliases-file' or using the
+`alias' command from Eshell allows you to create personalized
+commands not available in `helm-find-files' actions and use them
+from `\\<helm-find-files-map>\\[helm-ff-run-eshell-command-on-file]'.
+
+Example: You want a command to uncompress some \"*.tar.gz\" files from `helm-find-files':
+
+1) Create an Eshell alias named, say, \"untargz\" with the command
+\"alias untargz tar zxvf $*\".
+
+2) Now from `helm-find-files' select the \"*.tar.gz\" file (you can also
+mark files if needed) and hit `\\<helm-find-files-map>\\[helm-ff-run-eshell-command-on-file]'.
+
+Note: When using marked files with this, the meaning of the prefix argument is
+quite subtle. Say you have \"foo\", \"bar\" and \"baz\" marked; when you run
+the alias command `example' on these files with no prefix argument it will run
+`example' sequentially on each file:
+
+$ example foo
+$ example bar
+$ example baz
+
+With a prefix argument however it will apply `example' on all files at once:
+
+$ example foo bar baz
+
+Of course the alias command should support this.
+
+If you add %s to the command line %s will be replaced with the candidate, this mean you can
+add extra argument to your command e.g. command -extra-arg %s or command %s -extra-arg.
+If you want to pass many files inside %s, don't forget to use a prefix arg.
+
+You can also use special placeholders in extra-args,
+see the specific info page once you hit `\\<helm-find-files-map>\\[helm-ff-run-eshell-command-on-file]'.
+
+*** Using TRAMP with `helm-find-files' to read remote directories
+
+`helm-find-files' works fine with TRAMP despite some limitations.
+
+- Grepping files is not very well supported when used incrementally.
+See [[Grepping on remote files]].
+
+- Locate does not work on remote directories.
+
+**** A TRAMP syntax crash course
+
+Please refer to TRAMP's documentation for more details.
+
+- Connect to host 192.168.0.4 as user \"foo\":
+
+/scp:192.168.0.4@foo:
+
+- Connect to host 192.168.0.4 as user \"foo\" on port 2222:
+
+/scp:192.168.0.4@foo#2222:
+
+- Connect to host 192.168.0.4 as root using multihops syntax:
+
+/ssh:192.168.0.4@foo|sudo:192.168.0.4:
+
+Note: You can also use `tramp-default-proxies-alist' when connecting often to
+the same hosts.
+
+As a rule of thumb, prefer the scp method unless using multihops (which only
+works with the ssh method), especially when copying large files.
+
+You need to hit `C-j' once on top of a directory on the first connection
+to complete the pattern in the minibuffer.
+
+**** Display color for directories, symlinks etc... with tramp
+
+Starting at helm version 2.9.7 it is somewhat possible to
+colorize fnames by listing files without loosing performances with
+external commands (ls and awk) if your system is compatible.
+For this you can use `helm-list-dir-external' as value
+for `helm-list-directory-function'.
+
+See `helm-list-directory-function' documentation for more infos.
+
+**** Completing host
+
+As soon as you enter the first \":\" after method e.g =/scp:= you will
+have some completion about previously used hosts or from your =~/.ssh/config=
+file, hitting `\\[helm-execute-persistent-action]' or `right' on a candidate will insert this host in minibuffer
+without addind the ending \":\", second hit insert the last \":\".
+As soon the last \":\" is entered TRAMP will kick in and you should see the list
+of candidates soon after.
+
+When connection fails, be sure to delete your TRAMP connection with M-x
+`helm-delete-tramp-connection' before retrying.
+
+**** Editing local files as root
+
+Use the sudo method:
+
+\"/sudo:host:\" or simply \"/sudo::\".
+
+*** Attach files to a mail buffer (message-mode)
+
+If you are in a `message-mode' or `mail-mode' buffer, that action will appear
+in action menu, otherwise it is available at any time with \\<helm-find-files-map>\\[helm-ff-run-mail-attach-files].
+It behaves as follows:
+
+- If you are in a (mail or message) buffer, files are attached there.
+
+- If you are not in a mail buffer but one or more mail buffers exist, you are
+prompted to attach files to one of these mail buffers.
+
+- If you are not in a mail buffer and no mail buffer exists,
+a new mail buffer is created with the attached files in it.
+
+*** Open files in separate windows
+
+When [[Marked candidates][marking]] multiple files or using [[Use the wildcard to select multiple files][wildcard]], helm allow opening all
+this files in separate windows using an horizontal layout or a
+vertical layout if you used a prefix arg, when no more windows can be
+displayed in frame, next files are opened in background without being
+displayed. When using \\<helm-find-files-map>\\[helm-ff-run-switch-other-window] the current
+buffer is kept and files are displayed next to it with same behavior as above.
+When using two prefix args, files are opened in background without beeing displayed.
+
+*** Expand archives as directories in a avfs directory
+
+If you have mounted your filesystem with mountavfs,
+you can expand archives in the \"~/.avfs\" directory with \\<helm-map>\\[helm-execute-persistent-action].
+
+*** Tramp archive support (emacs-27+ only)
+
+If your emacs have library tramp-archive.el, you can browse the
+content of archives with emacs and BTW helm-find-files. However this beeing
+experimental and not very fast, helm doesn't provide an automatic
+expansion and detection of archives, you will have to add the final /
+manually and may have to force update (\\<helm-map>\\[helm-refresh])
+or remove and add again the final / until tramp finish decompressing archive.
+
+*** Touch files
+
+In the completion buffer, you can choose the default which is the current-time, it is
+the first candidate or the timestamp of one of the selected files.
+If you need to use something else, use \\<helm-map>\\[next-history-element] and edit
+the date in minibuffer.
+It is also a way to quickly create a new file without opening a buffer, saving it
+and killing it.
+To touch more than one new file, separate you filenames with a comma (\",\").
+If one wants to create (touch) a new file with comma inside the name use a prefix arg,
+this will prevent splitting the name and create multiple files.
+
+*** Delete files
+
+You can delete files without quitting helm with
+`\\<helm-find-files-map>\\[helm-ff-persistent-delete]' or delete files and quit helm with `\\[helm-ff-run-delete-file]'.
+
+In the second method you can choose to
+make this command asynchronous by customizing
+\`helm-ff-delete-files-function'.
+
+_WARNING_: When deleting files asynchronously you will NOT be
+WARNED if directories are not empty, that's mean non empty directories will
+be deleted in background without asking.
+
+A good compromise is to trash your files
+when using asynchronous method (see [[Trashing files][Trashing files]]).
+
+When choosing synchronous delete, you can allow recursive
+deletion of directories with `helm-ff-allow-recursive-deletes'.
+Note that when trashing (synchronous) you are not asked for recursive deletion.
+
+Note that `helm-ff-allow-recursive-deletes' have no effect when
+deleting asynchronously.
+
+First method (persistent delete) is always synchronous.
+
+Note that when a prefix arg is given, trashing behavior is inversed.
+See [[Trashing files][Trashing files]].
+
+**** Trashing files
+
+If you want to trash your files instead of deleting them you can
+set `delete-by-moving-to-trash' to non nil, like this your files
+will be moved to trash instead of beeing deleted.
+
+You can reverse at any time the behavior of `delete-by-moving-to-trash' by using
+a prefix arg with any of the delete files command.
+
+On GNULinux distributions, when navigating to a Trash directory you
+can restore any file in ..Trash/files directory with the 'Restore
+from trash' action you will find in action menu (needs the
+trash-cli package installed for remote files, see [[Trashing remote files with tramp][Here]]).
+You can as well delete files from Trash directories with the 'delete files from trash'
+action.
+If you want to know where a file will be restored, hit `M-i', you will find a trash info.
+
+Tip: Navigate to your Trash/files directories with `helm-find-files' and set a bookmark
+there with \\<helm-find-files-map>\\[helm-ff-bookmark-set] for fast access to Trash.
+
+NOTE: Restoring files from trash is working only on system using
+the [[http://freedesktop.org/wiki/Specifications/trash-spec][freedesktop trash specifications]].
+
+_WARNING:_
+
+If you have an ENV var XDG_DATA_HOME in your .profile or .bash_profile
+and this var is set to something like $HOME/.local/share (like preconized)
+`move-file-to-trash' may try to create $HOME/.local/share/Trash (literally)
+and its subdirs in the directory where you are actually trying to trash files.
+because `move-file-to-trash' is interpreting XDG_DATA_HOME literally instead
+of evaling its value (with `substitute-in-file-name').
+
+***** Trashing remote files with tramp
+
+Trashing remote files (or local files with sudo method) is disabled by default
+because tramp is requiring the 'trash' command to be installed, if you want to
+trash your remote files, customize `helm-trash-remote-files'.
+The package on most GNU/Linux based distributions is trash-cli, it is available [[https://github.com/andreafrancia/trash-cli][here]].
+
+NOTE:
+When deleting your files with sudo method, your trashed files will not be listed
+with trash-list until you log in as root.
+
+*** Checksum file
+
+Checksum is calculated with the md5sum, sha1sum, sha224sum,
+sha256sum, sha384sum and sha512sum when available, otherwise the
+Emacs function `secure-hash' is used but it is slow and may crash
+Emacs and even the whole system as it eats all memory. So if
+your system doesn't have the md5 and sha command line tools be
+careful when checking sum of larges files e.g. isos.
+
+*** Ignored or boring files
+
+Helm-find-files can ignore files matching
+`helm-boring-file-regexp-list' or files that are git ignored, you
+can set this with `helm-ff-skip-boring-files' or
+`helm-ff-skip-git-ignored-files'.

+
+This is `%s' read file name completion that have been \"helmized\"
+because you have enabled [[Helm mode][helm-mode]]'.
+Don't confuse this with `helm-find-files' which is a native helm command,
+see [[Helm functions vs helmized Emacs functions]].
+
+** Tips
+
+*** Navigation
+
+**** Enter `~/' at end of pattern to quickly reach home directory
+
+**** Enter `/' at end of pattern to quickly reach the file system root
+
+**** Enter `./' at end of pattern to quickly reach `default-directory'
+
+\(As per its value at the beginning of the session.)
+
+If you already are in the `default-directory' this will move the cursor to the top.
+
+**** Enter `../' at end of pattern will reach upper directory, moving cursor on top
+
+This is different from using `\\[helm-find-files-up-one-level]' in that it moves
+the cursor to the top instead of remaining on the previous subdir name.
+
+**** You can complete with partial basename
+
+It starts from the third character of the pattern.
+
+For instance \"fob\" or \"fbr\" will complete \"foobar\" but \"fb\" needs a
+third character in order to complete it.
+
+*** Persistent actions
+
+By default `helm-read-file-name' uses the persistent actions of `helm-find-files'.
+
+**** Use `\\[universal-argument] \\<helm-map>\\[helm-execute-persistent-action]' to display an image
+
+**** `\\<helm-map>\\[helm-execute-persistent-action]' on a filename will expand to this filename in Helm-buffer
+
+Second hit displays the buffer filename.
+Third hit kills the buffer filename.
+Note: `\\[universal-argument] \\<helm-map>\\[helm-execute-persistent-action]' displays the buffer directly.
+
+**** Browse images directories with `helm-follow-mode' and navigate up/down
+
+*** Delete characters backward
+
+When you want to delete characters backward, e.g. to create a new file or directory,
+auto-update may come in the way when it keeps updating to an existent directory.
+In that case, type `C-<backspace>' and then `<backspace>'.
+This should not be needed when copying/renaming files because autoupdate is disabled
+by default in that case.
+
+Note: On a terminal, the default binding `C-<backspace>' may not work.
+In this case use `C-c <backspace>'.
+
+*** Create new directories and files
+
+**** You can create a new directory and a new file at the same time
+
+Simply write the path in prompt and press `RET', e.g.
+\"~/new/newnew/newnewnew/my_newfile.txt\".
+
+**** To create a new directory, append a \"/\" at to the new name and press `RET'
+
+**** To create a new file, enter a filename not ending with \"/\"
+
+File and directory creation works only with some commands (e.g. `find-file')
+and it will not work with others where it is not intended to return a file or
+a directory \(e.g `list-directory').
+
+*** Exiting minibuffer with empty string
+
+You can exit minibuffer with empty string with \\<helm-read-file--map>\\[helm-cr-empty-string].
+It is useful when some commands are prompting continuously until you enter an empty prompt.

+ "* Helm Generic files
+
+** Tips
+
+*** Locate
+
+You can append to the search pattern any of the locate command line options,
+e.g. -b, -e, -n <number>, etc. See the locate(1) man page for more details.
+
+Some other sources (at the moment \"recentf\" and \"file in current directory\")
+support the -b flag for compatibility with locate when they are used with it.
+
+When you enable fuzzy matching on locate with `helm-locate-fuzzy-match', the
+search will be performed on basename only for efficiency (so don't add \"-b\" at
+prompt). As soon as you separate the patterns with spaces, fuzzy matching will
+be disabled and search will be done on the full filename. Note that in
+multi-match, fuzzy is completely disabled, which means that each pattern is a
+match regexp (i.e. \"helm\" will match \"helm\" but \"hlm\" will \*not* match
+\"helm\").
+
+*** Browse project
+
+When the current directory is not under version control, don't forget to refresh
+the cache when files have been added/removed in the directory.
+
+*** Find command
+
+Recursively search files using the \"find\" shell command.
+
+Candidates are all filenames that match all given globbing patterns. This
+respects the options `helm-case-fold-search' and
+`helm-findutils-search-full-path'.
+
+You can pass arbitrary \"find\" options directly after a \"*\" separator.
+For example, this would find all files matching \"book\" that are larger

+(defvar helm-grep-help-message
+ "* Helm Grep
+
+** Tips
+
+*** Use a prefix argument to grep recursively
+
+With Helm supporting git-grep and AG however, you are better off using one of
+them for recursive searches.
+
+*** You can use wild cards when selecting files (e.g. \"*.el\")
+
+*** You can grep in many different directories by marking files or using wild cards
+
+*** You can save the result in a `helm-grep-mode' buffer
+
+See [[Commands][commands]] below.
+
+Once in that buffer you can use \"emacs-wgrep\" (external package not bundled with Helm)
+to edit your changes.
+
+*** Helm-grep supports multi-matching
+
+\(Starting from version 1.9.4.)
+
+Simply add a space between each pattern as for most Helm commands.
+
+*** See full path of selected candidate
+
+Add (helm-popup-tip-mode 1) in your init file or enable it interactively with
+M-x helm-popup-tip-mode.
+
+*** Open file in other window
+
+The command \\<helm-grep-map>\\[helm-grep-run-other-window-action] allow you to open file
+in other window horizontally or vertically if a prefix arg is supplied.
+
+*** Performance over TRAMP
+
+Grepping works but it is badly supported as TRAMP doesn't support multiple
+processes running in a short delay (less than 5s) among other things.
+
+Helm uses a special hook to suspend the process automatically while you are
+typing. Even if Helm handles this automatically by delaying each process by 5s,
+you are adviced to this manually by hitting `\\<helm-map>\\[helm-toggle-suspend-update]' (suspend process) before
+typing, and hit again `\\<helm-map>\\[helm-toggle-suspend-update]' when the regexp is ready to send to the remote
+process. For simple regexps, there should be no need for this.
+
+Another solution is to not use TRAMP at all and mount your remote file system via
+SSHFS.
+
+* Helm GID
+
+** Tips
+
+Helm-GID reads the database created with the `mkid' command from id-utils.
+The name of the database file can be customized with `helm-gid-db-file-name', it
+is usually \"ID\".
+
+Helm-GID use the symbol at point as default-input. This command is also
+accessible from `helm-find-files' which allow you to navigate to another
+directory to consult its database.
+
+Note: Helm-GID supports multi-matches but only the last pattern entered will be
+highlighted since there is no ~--color~-like option in GID itself.
+
+* Helm AG
+
+** Tips
+
+Helm-AG is different from grep or ack-grep in that it works on a directory and
+not on a list of files.
+
+You can ignore files and directories with a \".agignore\" file, local to a
+directory or global when placed in the home directory. \(See the AG man page for
+more details.) That file follows the same syntax as `helm-grep-ignored-files'
+and `helm-grep-ignored-directories'.
+
+As always you can access Helm AG from `helm-find-files'.
+
+Starting with version 0.30, AG accepts one or more TYPE arguments on its command
+line. Helm provides completion on these TYPE arguments when available with your
+AG version. Use a prefix argument when starting a Helm-AG session to enable this
+completion.
+
+Note: You can mark several types to match in the AG query. The first AG
+versions providing this feature allowed only one type, so in this case only the
+last mark will be used.
+
+* Helm git-grep
+
+Helm-git-grep searches the current directory, i.e the default directory or the
+directory in Helm-find-files. If this current directory is a subdirectory of a
+project and you want to also match parent directories (i.e the whole project),
+use a prefix argument.

+*** Pass extra arguments after filename

+But you can also pass an argument or more after \"candidate_file\" like this:
+
+ <command> %s [extra_args]
+
+\"candidate_file\" will be added at \"%s\" and the command will look at this:
+
+ <command> candidate_file [extra_args]
+
+**** Use placeholders in extra arguments
+
+placeholder for file without extension: \\@
+placeholder for incremental number: \\#
+
+\"candidate_file\" will be added at \"%s\" and \\@ but without extension.
+
+ <command %s \\@>
+
+\"candidate_file\" will be added at \"%s\" and \\# will be replaced by an incremental number.
+
+ <command> %s \\#
+
+Here examples:
+
+Say you want to use the =convert= command to convert all your .png files in a directory to .jpg.
+
+This will convert all your files to jpg keeping the same basename.
+
+ convert %s \\@.jpg
+
+This will convert all your files to foo-001.jpg, foo-002.jpg etc...
+
+ convert %s foo-\\#.jpg
+
+You can of course combine both placeholders if needed.
+
+ convert %s \\@-\\#.jpg
+
+*** Specify marked files as arguments
+
+Example:

+ <command> file1 file2...
+
+Call `helm-find-files-eshell-command-on-file' with one prefix argument. Otherwise
+you can pass one prefix argument from the command selection buffer.

+** Tips
+
+*** Matching
+
+Multiple regexp matching is allowed, simply enter a space to separate the regexps.
+
+Matching empty lines is supported with the regexp \"^$\", you then get the
+results displayed as the buffer-name and the line number only. You can
+save and edit these results, i.e. add text to the empty line.
+
+*** Automatically match symbol at point
+
+Helm can automatically match the symbol at point while keeping the minibuffer
+empty, ready to be written to. This behaviour is disabled by default. To
+enable this you need to add `helm-source-occur' and `helm-source-moccur' to
+`helm-sources-using-default-as-input'.
+
+*** Jump to the corresponding line in the searched buffer
+
+You can do this with `\\<helm-map>\\[helm-execute-persistent-action]' (persistent-action), to do it repeatedly
+you can use `\\<helm-map>\\[helm-follow-action-forward]' and `\\<helm-map>\\[helm-follow-action-backward]' or enable `helm-follow-mode' with `\\<helm-map>\\[helm-follow-mode]'.
+Follow mode is enabled by default in helm-occur.
+
+*** Switch to buffer in other window
+
+The command \\<helm-moccur-map>\\[helm-moccur-run-goto-line-ow] allow you to switch to buffer
+in other window horizontally or vertically if a prefix arg is supplied.
+
+*** Save the results
+
+Similarly to Helm-grep, you can save the results with `\\<helm-occur-map>\\[helm-occur-run-save-buffer]'.
+Once in the saved buffer, you can edit it, see [[Edit a saved buffer][below]].
+
+Of course if you don't save the results, you can resume the Helm session with
+`helm-resume'.
+
+*** Refresh the resumed session
+
+When the buffer(s) where you ran helm-(m)occur get(s) modified, the Helm buffer
+will flash red as a warning. You can refresh the buffer by running `\\<helm-map>\\[helm-refresh]'.
+This can be done automatically by customizing `helm-moccur-auto-update-on-resume'.
+
+*** Refresh a saved buffer
+
+Type `g' to update the buffer.
+
+*** Edit a saved buffer
+
+First, install wgrep (https://github.com/mhayashi1120/Emacs-wgrep) and then:
+
+1) `C-c C-p' (`wgrep-change-to-wgrep-mode') to edit the buffer(s).
+2) `C-x C-s' to save your changes.
+
+Tip: Use the excellent iedit (https://github.com/victorhge/iedit) to modify all
+occurences at once in the buffer.
+
+*** Search in region
+
+When searching in current-buffer with `helm-occur', if a region
+is found helm will search in this region only. If you marked
+this region with `mark-defun' the symbol that was at point before
+marking defun will be used when `helm-source-occur' is member of
+`helm-sources-using-default-as-input'.

+
+ (setq async-bytecomp-allowed-packages '(all))
+
+*** Upgrade Elisp packages
+
+On initialization (when Emacs is fetching packages on remote), if Helm finds
+packages to upgrade, it will start in the upgradable packages view showing the packages
+available for upgrade.
+
+On subsequent runs, you will have to refresh the list with `C-c \\[universal-argument]'. If Helm
+finds upgrades you can switch to upgrade view (see below) to see what packages
+are available for upgrade or simply hit `C-c U' to upgrade them all.
+
+To see upgradable packages hit `M-U'.
+
+Then you can install all upgradable packages with the \"upgrade all\" action
+\(`C-c \\[universal-argument]'), or upgrade only specific packages by marking them and running the
+\"upgrade\" action (visible only when there are upgradable packages). Of course

+*** You can get help on any command with persistent action (\\[helm-execute-persistent-action])
+
+*** Prefix arguments
+
+You must pass prefix arguments \*after* starting `helm-M-x'. A mode-line
+counter will display the number of given prefix arguments.
+
+If you pass prefix arguments before running `helm-M-x', it will be displayed in the prompt.
+The first `\\[universal-argument]' after `helm-M-x' clears those prefix arguments.")

+- Start recording a kmacro with `f3'.
+- End the kmacro recording with `f4'.
+- Run `helm-execute-kmacro' to list all your kmacros.
+
+Use persistent action to run your kmacro as many time as needed.
+You can browse the kmacros with `helm-next-line' and `helm-previous-line'.

+;;; Kill ring

+(defvar helm-kill-ring-help-message
+ "* Helm kill ring
+
+** Tips
+
+Every Helm session lets you save a candidate to the kill-ring / clipboard /
+primary-selection with `\\<helm-map>\\[helm-kill-selection-and-quit]'.
+
+To save space, Helm-kill-ring truncates the candidates longer than
+`helm-kill-ring-max-offset'.
+`\\<helm-kill-ring-map>\\[helm-kill-ring-kill-selection]' then saves the whole
+text and not the truncated value. The view of truncated candidates can be
+toggled; see the command list below.
+
+As opposed to `yank', numeric prefix arguments are ignored with
+`helm-show-kill-ring': there is no need for them since selection happens within
+Helm. Moreover Helm has [[Shortcuts for executing the default action on the n-th candidate][Shortcuts for executing the default action on the n-th candidate]].
+
+It is recommended to globally bind `M-y' to `helm-show-kill-ring'. Once in the
+Helm-kill-ring session you can navigate to next/previous line with `M-y' and
+`M-u' for convenience. Of course `\\[helm-next-line]' and `\\[helm-previous-line]' are still available.
+
+It is possible to delete candidates from the kill ring with `\\<helm-kill-ring-map>\\[helm-kill-ring-delete]'
+but also persistently with `\\<helm-kill-ring-map>\\[helm-kill-ring-run-persistent-delete]'.
+
+You can concatenate marked candidates and yank them in the current
+buffer, thus creating a new entry in the kill ring. Candidates are
+concatenated with `helm-kill-ring-separator' as default but you can
+change interactively the separator while yanking by using two prefix
+args. When you have something else than \"\\n\" as default value for
+`helm-kill-ring-separator' and you want to use \"\\n\" from prompt, use
+`C-q C-j' to enter a newline in prompt.
+
+To not push a new entry in the kill ring, use `\\<helm-map>\\[helm-copy-to-buffer]' instead of RET
+\(note that you can't change separator with this).
+
+When inserting candidates with the default action (`RET'), `point' is placed at
+the end of the candidate and `mark' at the beginning. You can revert this behavior
+by using a prefix argument, i.e. `C-u RET', like the regular `yank' command does.
+
+** Commands
+\\<helm-kill-ring-map>
+\\[helm-next-line]\t\tNext line.
+\\[helm-previous-line]\t\tPrevious line.
+\\[helm-kill-ring-delete]\t\tDelete entry.
+\\[helm-kill-ring-toggle-truncated]\t\tToggle truncated view of candidate.

+ "Completing read functions for specific Emacs commands.
+
+By default `helm-mode' use `helm-completing-read-default-handler' to
+provide helm completion in each `completing-read' or `read-file-name'
+found, but other functions can be specified here for specific
+commands. This also allow disabling helm completion for some commands
+when needed.
+
+Each entry is a cons cell like (EMACS_COMMAND . COMPLETING-READ_HANDLER)
+where key and value are symbols.
+
+Each key is an Emacs command that use originaly `completing-read'.
+
+Each value maybe a helm function that takes same arguments as
+`completing-read' plus NAME and BUFFER, where NAME is the name of the new
+helm source and BUFFER the name of the buffer we will use, but it can
+be also a function not using helm, in this case the function should
+take same args as `completing-read' and not be prefixed by \"helm-\".
+
+`helm' will use the name of the command calling `completing-read' as
+NAME and BUFFER will be computed as well with NAME but prefixed with
+\"*helm-mode-\".
+
+This function prefix name must start by \"helm-\" when it uses helm,
+otherwise `helm' assumes the function is not a helm function and
+expects same args as `completing-read', this allow you to define a
+handler not using helm completion.
+
+Example:
+
+ (defun foo/test ()
+ (interactive)
+ (message \"%S\" (completing-read \"test: \" '(a b c d e))))
+
+ (defun helm-foo/test-completing-read-handler (prompt collection
+ predicate require-match
+ initial-input hist def
+ inherit-input-method
+ name buffer)
+ (helm-comp-read prompt collection :marked-candidates t
+ :name name
+ :buffer buffer))
+
+ (add-to-list 'helm-completing-read-handlers-alist
+ '(foo/test . helm-foo/test-completing-read-handler))
+
+
+We want here to make the regular `completing-read' in `foo/test'
+returns a list of candidate(s) instead of a single candidate.
+

+your specialized function should handle the both.
+
+If the value of an entry is nil completion will fall back to

+
+If you want to disable helm completion for `describe-function', use:
+
+ (describe-function . nil)
+
+Ido is also supported, you can use `ido-completing-read' and
+`ido-read-file-name' as value of an entry or just 'ido.

+
+- COLLECTION can be a list, vector, obarray or hash-table.
+ It can be also a function that receives three arguments:
+ the values string, predicate and t. See `all-completions' for more details.
+
+Keys description:
+
+- TEST: A predicate called with one arg i.e candidate.
+
+- INITIAL-INPUT: Same as input arg in `helm'.
+
+- PRESELECT: See preselect arg of `helm'.
+
+- DEFAULT: This option is used only for compatibility with regular
+ Emacs `completing-read' (Same as DEFAULT arg of `completing-read').
+
+- BUFFER: Name of helm-buffer.
+
+- MUST-MATCH: Candidate selected must be one of COLLECTION.
+
+- FUZZY: Enable fuzzy matching.
+
+- REVERSE-HISTORY: When non--nil display history source after current
+ source completion.
+
+- REQUIRES-PATTERN: Same as helm attribute, default is 0.
+
+- HISTORY: A list containing specific history, default is nil.
+ When it is non--nil, all elements of HISTORY are displayed in
+ a special source before COLLECTION.
+
+- INPUT-HISTORY: A symbol. the minibuffer input history will be
+ stored there, if nil or not provided, `minibuffer-history'
+ will be used instead.
+
+- CASE-FOLD: Same as `helm-case-fold-search'.
+
+- DEL-INPUT: Boolean, when non--nil (default) remove the partial
+ minibuffer input from HISTORY is present.
+
+- PERSISTENT-ACTION: A function called with one arg i.e candidate.
+
+- PERSISTENT-HELP: A string to document PERSISTENT-ACTION.
+
+- MODE-LINE: A string or list to display in mode line.
+ Default is `helm-comp-read-mode-line'.
+
+- KEYMAP: A keymap to use in this `helm-comp-read'.
+ (the keymap will be shared with history source)
+
+- NAME: The name related to this local source.
+
+- HEADER-NAME: A function to alter NAME, see `helm'.
+
+- EXEC-WHEN-ONLY-ONE: Bound `helm-execute-action-at-once-if-one'
+ to non--nil. (possibles values are t or nil).
+
+- VOLATILE: Use volatile attribute.
+
+- SORT: A predicate to give to `sort' e.g `string-lessp'
+ Use this only on small data as it is ineficient.
+ If you want to sort faster add a sort function to
+ FC-TRANSFORMER.
+ Note that FUZZY when enabled is already providing a sort function.
+
+- FC-TRANSFORMER: A `filtered-candidate-transformer' function
+ or a list of functions.
+
+- HIST-FC-TRANSFORMER: A `filtered-candidate-transformer'
+ function for the history source.
+
+- MARKED-CANDIDATES: If non--nil return candidate or marked candidates as a list.
+
+- NOMARK: When non--nil don't allow marking candidates.
+
+- ALISTP: (default is non--nil) See `helm-comp-read-get-candidates'.
+
+- CANDIDATES-IN-BUFFER: when non--nil use a source build with
+ `helm-source-in-buffer' which is much faster.
+ Argument VOLATILE have no effect when CANDIDATES-IN-BUFFER is non--nil.
+
+- MATCH-PART: Allow matching only one part of candidate.
+ See match-part documentation in `helm-source'.
+
+- MATCH-DYNAMIC: See match-dynamic in `helm-source-sync'
+ It have no effect when used with CANDIDATES-IN-BUFFER.
+
+- ALLOW-NEST: Allow nesting this `helm-comp-read' in a helm session.
+ See `helm'.
+
+- MULTILINE: See multiline in `helm-source'.
+
+- GROUP: See group in `helm-source'.
+
+Any prefix args passed during `helm-comp-read' invocation will be recorded
+in `helm-current-prefix-arg', otherwise if prefix args were given before

+
+;;; Commentary:
+
+;; A bibliography manager for Emacs, based on Helm and the
+;; bibtex-completion backend.
+;;
+;; News:
+;; - 09/06/2018: Added virtual APA field `author-or-editor` for use in
+;; notes templates.
+;; - 02/06/2018: Reload bibliography proactively when bib files are
+;; changed.
+;; - 21/10/2017: Added support for multiple PDFs and other file
+;; types. See `bibtex-completion-pdf-extension' and
+;; `bibtex-completion-find-additional-pdfs' for details.
+;; - 10/10/2017: Added support for ~@string~ constants.
+;; - 02/10/2017: Date field is used when year is undefined.
+;; - 29/09/2017: BibTeX entry, citation macro, or org-bibtex entry at
+;; point, will be pre-selected in helm-bibtex and ivy-bibtex giving
+;; quick access to PDFs and other functions.
+;;
+;; See NEWS.org for old news.
+;;
+;; Key features:
+;; - Quick access to your bibliography from within Emacs
+;; - Powerful search capabilities
+;; - Provides instant search results as you type
+;; - Tightly integrated with LaTeX authoring, emails, Org mode, etc.
+;; - Open the PDFs, URLs, or DOIs associated with an entry
+;; - Insert LaTeX cite commands, Ebib links, or Pandoc citations,
+;; BibTeX entries, or plain text references at point, attach PDFs to
+;; emails
+;; - Support for note taking
+;; - Quick access to online bibliographic databases such as Pubmed,
+;; arXiv, Google Scholar, Library of Congress, etc.
+;; - Imports BibTeX entries from CrossRef and other sources.
+;;
+;; See the github page for details:
+;;
+;; https://github.com/tmalsburg/helm-bibtex
+
+;;; Install:
+
+;; Put this file in a directory included in your load path or install
+;; helm-bibtex from MELPA (preferred). Then add the following in your
+;; Emacs startup file:
+;;
+;; (require 'helm-bibtex)
+;;
+;; Alternatively, you can use autoload:
+;;
+;; (autoload 'helm-bibtex "helm-bibtex" "" t)
+;;
+;; Requirements are parsebib, helm, s, dash, and f. The easiest way
+;; to install these packages is through MELPA. Make sure helm is
+;; properly configured (see
+;; https://github.com/emacs-helm/helm#install-from-emacs-packaging-system).
+;;
+;; Let helm-bibtex know where it can find your bibliography by setting
+;; the variable `bibtex-completion-bibliography'. See the manual for
+;; more details:
+;;
+;; https://github.com/tmalsburg/helm-bibtex#minimal-configuration
+
+;;; Usage:
+
+;; You can search entries using the command `helm-bibtex'. Select an
+;; entry and press TAB to access all available actions. At the end of
+;; the list of matches you find some dummy entries that can be used
+;; for searching in online databases. Apart from that, familiarize
+;; yourself with Helm. It's more powerful that you might think.
+
+;;; Code:
+
+(require 'helm)
+(require 'helm-net)
+(require 'helm-easymenu)

-** Keywords
-
-Keywords supported:
-
-- :sources
-- :input
-- :prompt
-- :resume
-- :preselect
-- :buffer
-- :keymap
-- :default
-- :history
-- :allow-nest
-
-Extra LOCAL-VARS keywords are supported, see the \"** Other
-keywords\" section below.
-
-Basic keywords are the following:
-
-*** :sources
-
-One of the following:
-
-- List of sources
-- Symbol whose value is a list of sources
-- Alist representing a Helm source.
- - In this case the source has no name and is referenced in
- `helm-sources' as a whole alist.
-
-*** :input
-
-Initial input of minibuffer (temporary value of `helm-pattern')
-
-*** :prompt
-
-Minibuffer prompt. Default value is `helm--prompt'.
-
-*** :resume
-
-If t, allow resumption of the previous session of this Helm
-command, skipping initialization.
-
-If 'noresume, this instance of `helm' cannot be resumed.
-
-*** :preselect
-
-Initially selected candidate (string or regexp).
-
-*** :buffer
-
-Buffer name for this Helm session. `helm-buffer' will take this value.
-
-*** :keymap
-
-\[Obsolete]
-
-Keymap used at the start of this Helm session.
-
-It is overridden by keymaps specified in sources, and is kept
-only for backward compatibility.
-
-Keymaps should be specified in sources using the :keymap slot
-instead. See `helm-source'.
-
-This keymap is not restored by `helm-resume'.
-
-*** :default
-
-Default value inserted into the minibuffer with
-\\<minibuffer-local-map>\\[next-history-element].
-
-It can be a string or a list of strings, in this case
-\\<minibuffer-local-map>\\[next-history-element] cycles through
-the list items, starting with the first.
-
-If nil, `thing-at-point' is used.
-
-If `helm--maybe-use-default-as-input' is non-`nil', display is
-updated using this value, unless :input is specified, in which
-case that value is used instead.
-
-*** :history
-
-Minibuffer input, by default, is pushed to `minibuffer-history'.
-
-When an argument HISTORY is provided, input is pushed to
-HISTORY. HISTORY should be a valid symbol.
-
-*** :allow-nest
-
-Allow running this Helm command in a running Helm session.
-
-** Other keywords
-
-Other keywords are interpreted as local variables of this Helm
-session. The `helm-' prefix can be omitted. For example,
-
-\(helm :sources 'helm-source-buffers-list
- :buffer \"*helm buffers*\"
- :candidate-number-limit 10)
-
-starts a Helm session with the variable
-`helm-candidate-number-limit' set to 10.
-
-** Backward compatibility
-
-For backward compatibility, positional parameters are
-supported:
-
-\(helm sources input prompt resume preselect
- buffer keymap default history allow-nest)
-
-However, the use of non-keyword args is deprecated.
-
-\(fn &key SOURCES INPUT PROMPT RESUME PRESELECT BUFFER KEYMAP DEFAULT HISTORY ALLOW-NEST OTHER-LOCAL-VARS)" nil nil)

- "* Helm Generic Help
-** Basics
-
-Helm narrows down the list of candidates as you type a filter pattern.
-
-Helm accepts multiple space-separated patterns, each pattern can be negated with \"!\".
-
-Helm also supports fuzzy matching in some places when specified, you will find
-several variables to enable fuzzy matching in diverse sources,
-see [[https://github.com/emacs-helm/helm/wiki/Fuzzy-matching][fuzzy-matching]] in helm-wiki for more infos.
-
-Helm generally uses familiar Emacs keys to navigate the list.
-Here follow some of the less obvious bindings:
-
-- `\\[helm-maybe-exit-minibuffer]' selects the candidate from the list, executes the default action
-upon exiting the Helm session.
-
-- `\\[helm-execute-persistent-action]' executes the default action but without exiting the Helm session.
-Not all sources support this.
-
-- `\\[helm-select-action]' displays a list of actions available on current candidate or all marked candidates.
-The default binding <tab> is ordinarily used for completion, but that would be
-redundant since Helm completes upon every character entered in the prompt.
-See [[https://github.com/emacs-helm/helm/wiki#helm-completion-vs-emacs-completion][Helm wiki]].
-
-Note: In addition to the default actions list, additional actions appear
-depending of the type of the selected candidate(s). They are called filtered
-actions.
-
-** Helm mode
-
-`helm-mode' toggles Helm completion in native Emacs functions,
-so when you turn `helm-mode' on, commands like `switch-to-buffer' will use
-Helm completion instead of the usual Emacs completion buffer.
-
-*** What gets or does not get \"helmized\" when `helm-mode' is enabled?
-
-Helm provides generic completion on all Emacs functions using `completing-read',
-`completion-in-region' and their derivatives, e.g. `read-file-name'. Helm
-exposes a user variable to control which function to use for a specific Emacs
-command: `helm-completing-read-handlers-alist'. If the function for a specific
-command is nil, it turns off Helm completion. See the variable documentation
-for more infos.
-
-*** Helm functions vs helmized Emacs functions
-
-While there are Helm functions that perform the same completion as other
-helmized Emacs functions, e.g. `switch-to-buffer' and `helm-buffers-list', the
-native Helm functions like `helm-buffers-list' can receive new features, the
-allow marking candidates, they have several actions, etc. Whereas the helmized
-Emacs functions only have Helm completion, one action and no more then Emacs can
-provide for this function. This is the intended behavior.
-
-Generally you are better off using the native Helm command
-than the helmized Emacs equivalent.
-
-** Helm help
-
-\\[helm-documentation]: Show all helm documentations concatenated in one org file.
-
-From a Helm session, just hit \\<helm-map>\\[helm-help] to have the
-documentation for the current source followed by the global Helm documentation.
-
-While in the help buffer, most of the regular keybindings are available in an
-Emacs buffers; the most important ones are shown in minibuffer. However due to
-the implementation restrictions, no regular Emacs keymap is used (it runs in a
-loop when reading the help buffer) they are hardcoded and not modifiable.
-
-The hard-coded documentation bindings are:
-
-| Key | Alternative keys | Command |
-|-----------+------------------+---------------------|
-| C-v | Space next | Scroll up |
-| M-v | b prior | Scroll down |
-| C-s | | Isearch forward |
-| C-r | | Isearch backward |
-| C-a | | Beginning of line |
-| C-e | | End of line |
-| C-f | right | Forward char |
-| C-b | left | Backward char |
-| C-n | down | Next line |
-| C-p | up | Previous line |
-| M-a | | Backward sentence |
-| M-e | | Forward sentence |
-| M-f | | Forward word |
-| M-b | | Backward word |
-| M-> | | End of buffer |
-| M-< | | Beginning of buffer |
-| C-<SPACE> | | Toggle mark |
-| RET | | Follow org link |
-| C-% | | Push org mark |
-| C-& | | Goto org mark-ring |
-| TAB | | Org cycle |
-| M-<TAB> | | Toggle visibility |
-| M-w | | Copy region |
-| q | | Quit |
-
-** Customize Helm
-
-Helm provides a lot of user variables for extensive customization.
-From any Helm session, type \\<helm-map>\\[helm-customize-group] to jump to the current source `custom' group.
-Helm also has a special group for faces you can access via `M-x customize-group RET helm-faces'.
-
-Note: Some sources may not have their group set and default to the `helm' group.
-
-** Helm's basic operations and default key bindings
-
-| Key | Alternative Keys | Command |
-|---------+------------------+----------------------------------------------------------------------|
-| C-p | Up | Previous line |
-| C-n | Down | Next line |
-| M-v | prior | Previous page |
-| C-v | next | Next page |
-| Enter | | Execute first (default) action / Select |
-| M-< | | First line |
-| M-> | | Last line |
-| C-M-S-v | M-prior, C-M-y | Previous page (other-window) |
-| C-M-v | M-next | Next page (other-window) |
-| Tab | C-i | Show action list |
-| Left | | Previous source |
-| Right | C-o | Next source |
-| C-k | | Delete pattern (with prefix arg delete from point to end or all [1]) |
-| C-j | C-z | Persistent action (Execute and keep Helm session) |
-
-\[1] Delete from point to end or all depending on the value of
-`helm-delete-minibuffer-contents-from-point'.
-
-** Shortcuts for n-th action
-
-f1-f12: Execute n-th action where n is 1 to 12.
-
-** Shortcuts for executing the default action on the n-th candidate
-
-C-x <n>: Execute default action on the n-th candidate before currently selected candidate.
-
-C-c <n>: Execute default action on the n-th candidate after current selected candidate.
-
-\"n\" is limited to 1-9. For larger jumps use other navigation keys. Helm does
-not display line numbers by default: enable them with the
-\[[https://github.com/coldnew/linum-relative][linum-relative]] package and
-`helm-linum-relative-mode'.
-If you are using Emacs-26+ version you can use `global-display-line-numbers-mode'
-which seems even better (don't forget to customize `display-line-numbers-type' to relative).
-
-** Mouse control in Helm
-
-A basic support for the mouse is provided when the user sets `helm-allow-mouse' to non-nil.
-
-- mouse-1 selects the candidate.
-- mouse-2 executes the default action on selected candidate.
-- mouse-3 pops up the action menu.
-
-Note: When mouse control is enabled in Helm, it also lets you click around and lose
-the minibuffer focus: you'll have to click on the Helm buffer or the minibuffer
-to retrieve control of your Helm session.
-
-** Marked candidates
-
-You can mark candidates to execute an action on all of them instead of the
-current selected candidate only. (See bindings below.) Most Helm actions
-operate on marked candidates unless candidate-marking is explicitely forbidden
-for a specific source.
-
-- To mark/unmark a candidate, use \\[helm-toggle-visible-mark]. (See bindings below.)
-With a numeric prefix arg mark ARG candidates forward, if ARG is negative
-mark ARG candidates backward.
-
-- To mark all visible unmarked candidates at once in current source use \\[helm-mark-all].
-With a prefix argument, mark all candidates in all sources.
-
-- To unmark all visible marked candidates at once use \\[helm-unmark-all].
-
-- To mark/unmark all candidates at once use \\[helm-toggle-all-marks].
-With a prefix argument, mark/unmark all candidates in all sources.
-
-Note: When multiple candidates are selected across different sources, only the
-candidates of the current source will be used when executing most actions (as
-different sources can have different actions). Some actions support
-multi-source marking however.
-
-** Follow candidates
-
-When `helm-follow-mode' is on (\\<helm-map>\\[helm-follow-mode] to toggle it),
-moving up and down the Helm session or updating the list of candidates will
-automatically execute the persistent-action as specified for the current source.
-
-If `helm-follow-mode-persistent' is non-nil, the state of the mode will be
-restored for the following Helm sessions.
-
-If you just want to follow candidates occasionally without enabling
-`helm-follow-mode', you can use \\<helm-map>\\[helm-follow-action-forward] or \\[helm-follow-action-backward] instead.
-Conversely, when `helm-follow-mode' is enabled, those commands
-go to previous/next line without executing the persistent action.
-
-** Frequently Used Commands
-
-\\[helm-toggle-resplit-and-swap-windows]\t\tToggle vertical/horizontal split on first hit and swap Helm window on second hit.
-\\[helm-quit-and-find-file]\t\tDrop into `helm-find-files'.
-\\[helm-kill-selection-and-quit]\t\tKill display value of candidate and quit (with prefix arg, kill the real value).
-\\[helm-yank-selection]\t\tYank current selection into pattern.
-\\[helm-copy-to-buffer]\t\tCopy selected candidate at point in current buffer.
-\\[helm-follow-mode]\t\tToggle automatic execution of persistent action.
-\\[helm-follow-action-forward]\tRun persistent action then select next line.
-\\[helm-follow-action-backward]\t\tRun persistent action then select previous line.
-\\[helm-refresh]\t\tRecalculate and redisplay candidates.
-\\[helm-toggle-suspend-update]\t\tToggle candidate updates.
-
-** Special yes, no or yes for all answers
-
-You may be prompted in the minibuffer to answer by [y,n,!,q] in some places
-for confirmation.
-
-- y mean yes
-- no mean no
-- ! mean yes for all
-- q mean quit or abort current operation.
-
-When using ! you will not be prompted anymore for the same thing in current operation
-e.g. file deletion, file copy etc...
-
-** Moving in `helm-buffer'
-
-You can move in `helm-buffer' with the usual commands used in Emacs:
-\(\\<helm-map>\\[helm-next-line], \\<helm-map>\\[helm-previous-line], etc. See above basic commands.
-When `helm-buffer' contains more than one source, change source with \\<helm-map>\\[helm-next-source].
-
-Note: When reaching the end of a source, \\<helm-map>\\[helm-next-line] will *not* go to the next source unless
-variable `helm-move-to-line-cycle-in-source' is non-nil, so you will have to use \\<helm-map>\\[helm-next-source].
-
-** Resume previous session from current Helm session
-
-You can use `C-c n' (`helm-run-cycle-resume') to cycle in resumables sources.
-`C-c n' is a special key set with `helm-define-key-with-subkeys' which, after pressing it, allows you
-to keep cycling with further `n'.
-
-Tip: You can bound the same key in `global-map' to `helm-cycle-resume'
- with `helm-define-key-with-subkeys' to let you transparently cycle
- sessions, Helm fired up or not.
- You can also bind the cycling commands to single key presses (e.g. `S-<f1>') this time
- with a simple `define-key'. (Note that `S-<f1>' is not available in terminals.)
-
-Note: `helm-define-key-with-subkeys' is available only once Helm is loaded.
-
-You can also use \\<helm-map>\\[helm-resume-previous-session-after-quit] to resume
-the previous session, or \\<helm-map>\\[helm-resume-list-buffers-after-quit]
-to have completion on all resumable buffers.
-
-** Global commands
-
-*** Resume Helm session from outside Helm
-
-\\<global-map>\\[helm-resume] revives the last `helm' session. Binding a key to
-this command will greatly improve `helm' interactivity, e.g. when quitting Helm
-accidentally.
-
-You can call \\<global-map>\\[helm-resume] with a prefix argument to choose
-\(with completion!) which session you'd like to resume. You can also cycle in
-these sources with `helm-cycle-resume' (see above).
-
-** Debugging Helm
-
-Helm exposes the special variable `helm-debug': setting it to non-nil
-will enable Helm logging in a special outline-mode buffer.
-Helm resets the variable to nil at the end of each session.
-
-For convenience, \\<helm-map>\\[helm-enable-or-switch-to-debug]
-allows you to turn on debugging for this session only.
-To avoid accumulating log entries while you are typing patterns, you can use
-\\<helm-map>\\[helm-toggle-suspend-update] to turn off updating. When you
-are ready turn it on again to resume logging.
-
-Once you exit your Helm session you can access the debug buffer with
-`helm-debug-open-last-log'. It is possible to save logs to dated files when
-`helm-debug-root-directory' is set to a valid directory.
-
-Note: Be aware that Helm log buffers grow really fast, so use `helm-debug' only
-when needed.
-
-** Writing your own Helm sources
-
-Writing simple sources for your own usage is easy. When calling the `helm'
-function, the sources are added the :sources slot which can be a symbol or a
-list of sources. Sources can be built with different EIEIO classes depending
-what you want to do. To simplify this, several `helm-build-*' macros are
-provided. Below, simple examples to start with.
-
-We will not go further here, see [[https://github.com/emacs-helm/helm/wiki/Developing][Helm wiki]] and the source
-code for more information and more complex exapmles.
-
-#+begin_src elisp
-
- ;; Candidates are stored in a list.
- (helm :sources (helm-build-sync-source \"test\"
- ;; A function can be used as well
- ;; to provide candidates.
- :candidates '(\"foo\" \"bar\" \"baz\"))
- :buffer \"*helm test*\")
-
- ;; Candidates are stored in a buffer.
- ;; Generally faster but doesn't allow a dynamic updating
- ;; of the candidates list i.e the list is fixed on start.
- (helm :sources (helm-build-in-buffer-source \"test\"
- :data '(\"foo\" \"bar\" \"baz\"))
- :buffer \"*helm test*\")

-** Keywords
-
-Keywords supported:
-
-- :sources
-- :input
-- :prompt
-- :resume
-- :preselect
-- :buffer
-- :keymap
-- :default
-- :history
-- :allow-nest
-
-Extra LOCAL-VARS keywords are supported, see the \"** Other
-keywords\" section below.
-
-Basic keywords are the following:
-
-*** :sources
-
-One of the following:
-
-- List of sources
-- Symbol whose value is a list of sources
-- Alist representing a Helm source.
- - In this case the source has no name and is referenced in
- `helm-sources' as a whole alist.
-
-*** :input
-
-Initial input of minibuffer (temporary value of `helm-pattern')
-
-*** :prompt
-
-Minibuffer prompt. Default value is `helm--prompt'.
-
-*** :resume
-
-If t, allow resumption of the previous session of this Helm
-command, skipping initialization.
-
-If 'noresume, this instance of `helm' cannot be resumed.
-
-*** :preselect
-
-Initially selected candidate (string or regexp).
-
-*** :buffer
-
-Buffer name for this Helm session. `helm-buffer' will take this value.
-
-*** :keymap
-
-\[Obsolete]
-
-Keymap used at the start of this Helm session.
-
-It is overridden by keymaps specified in sources, and is kept
-only for backward compatibility.
-
-Keymaps should be specified in sources using the :keymap slot
-instead. See `helm-source'.
-
-This keymap is not restored by `helm-resume'.
-
-*** :default
-
-Default value inserted into the minibuffer \ with
-\\<minibuffer-local-map>\\[next-history-element].
-
-It can be a string or a list of strings, in this case
-\\<minibuffer-local-map>\\[next-history-element] cycles through
-the list items, starting with the first.
-
-If nil, `thing-at-point' is used.
-
-If `helm--maybe-use-default-as-input' is non-`nil', display is
-updated using this value, unless :input is specified, in which
-case that value is used instead.
-
-*** :history
-
-Minibuffer input, by default, is pushed to `minibuffer-history'.
-
-When an argument HISTORY is provided, input is pushed to
-HISTORY. HISTORY should be a valid symbol.
-
-*** :allow-nest
-
-Allow running this Helm command in a running Helm session.
-
-** Other keywords
-
-Other keywords are interpreted as local variables of this Helm
-session. The `helm-' prefix can be omitted. For example,
-
-\(helm :sources 'helm-source-buffers-list
- :buffer \"*helm buffers*\"
- :candidate-number-limit 10\)
-
-starts a Helm session with the variable
-`helm-candidate-number-limit' set to 10.
-
-** Backward compatibility
-
-For backward compatibility, positional parameters are
-supported:
-
-\(helm sources input prompt resume preselect
- buffer keymap default history allow-nest\)
-
-However, the use of non-keyword args is deprecated.

-(defun helm-candidates-in-buffer (&optional source)
- "The top level function used to store candidates with `helm-source-in-buffer'.
-
-Candidates are stored in a buffer generated internally
-by `helm-candidate-buffer' function.
-Each candidate must be placed in one line.
-
-The buffer is created and fed in the init attribute function of helm.
-
-e.g:
-
- (helm-build-in-buffer-source \"test\"
- :init (lambda ()
- (helm-init-candidates-in-buffer
- 'global '(foo foa fob bar baz))))
-
-A shortcut can be used to simplify:
-
- (helm-build-in-buffer-source \"test\"
- :data '(foo foa fob bar baz))
-
-By default, `helm' makes candidates by evaluating the
-candidates function, then narrows them by `string-match' for each
-candidate.
-
-But this is slow for large number of candidates. The new way is
-to store all candidates in a buffer and then narrow
-with `re-search-forward'. Search function is customizable by search
-attribute. The important point is that buffer processing is MUCH
-FASTER than string list processing and is the Emacs way.
-
-The init function writes all candidates to a newly-created
-candidate buffer. The candidates buffer is created or specified
-by `helm-candidate-buffer'. Candidates are stored in a line.
-
-The candidates function narrows all candidates, IOW creates a
-subset of candidates dynamically.
-
-Class `helm-source-in-buffer' is implemented with three attributes:
-
- (candidates . helm-candidates-in-buffer)
- (volatile)
- (match identity)
-
-The volatile attribute is needed because `helm-candidates-in-buffer'
-creates candidates dynamically and need to be called every
-time `helm-pattern' changes.
-
-Because `helm-candidates-in-buffer' plays the role of `match' attribute
-function, specifying `(match identity)' makes the source slightly faster.
-
-However if source contains `match-part' attribute, match is computed only
-on part of candidate returned by the call of function provided by this attribute.
-The function should have one arg, candidate, and return only
-a specific part of candidate.
-
-To customize `helm-candidates-in-buffer' behavior,
-use `search', `get-line' and `match-part' attributes."

+Keywords supported:
+
+- :sources
+- :input
+- :prompt
+- :resume
+- :preselect
+- :buffer
+- :keymap
+- :default
+- :history
+- :allow-nest
+
+Extra LOCAL-VARS keywords are supported, see the \"** Other
+keywords\" section below.
+
+Basic keywords are the following:
+
+*** :sources
+
+One of the following:
+
+- List of sources
+- Symbol whose value is a list of sources
+- Alist representing a Helm source.
+ - In this case the source has no name and is referenced in
+ `helm-sources' as a whole alist.
+
+*** :input
+
+Initial input of minibuffer (temporary value of `helm-pattern')
+
+*** :prompt
+
+Minibuffer prompt. Default value is `helm--prompt'.
+
+*** :resume
+
+If t, allow resumption of the previous session of this Helm
+command, skipping initialization.
+
+If 'noresume, this instance of `helm' cannot be resumed.
+
+*** :preselect
+
+Initially selected candidate (string or regexp).
+
+*** :buffer
+
+Buffer name for this Helm session. `helm-buffer' will take this value.
+
+*** :keymap
+
+\[Obsolete]
+
+Keymap used at the start of this Helm session.
+
+It is overridden by keymaps specified in sources, and is kept
+only for backward compatibility.
+
+Keymaps should be specified in sources using the :keymap slot
+instead. See `helm-source'.
+
+This keymap is not restored by `helm-resume'.
+
+*** :default
+
+Default value inserted into the minibuffer with
+\\<minibuffer-local-map>\\[next-history-element].
+
+It can be a string or a list of strings, in this case
+\\<minibuffer-local-map>\\[next-history-element] cycles through
+the list items, starting with the first.
+
+If nil, `thing-at-point' is used.
+
+If `helm--maybe-use-default-as-input' is non-`nil', display is
+updated using this value, unless :input is specified, in which
+case that value is used instead.
+
+*** :history
+
+Minibuffer input, by default, is pushed to `minibuffer-history'.
+
+When an argument HISTORY is provided, input is pushed to
+HISTORY. HISTORY should be a valid symbol.
+
+*** :allow-nest
+
+Allow running this Helm command in a running Helm session.
+
+** Other keywords
+
+Other keywords are interpreted as local variables of this Helm
+session. The `helm-' prefix can be omitted. For example,
+
+\(helm :sources 'helm-source-buffers-list
+ :buffer \"*helm buffers*\"
+ :candidate-number-limit 10)
+
+starts a Helm session with the variable
+`helm-candidate-number-limit' set to 10.
+
+** Backward compatibility
+
+For backward compatibility, positional parameters are
+supported:
+
+\(helm sources input prompt resume preselect
+ buffer keymap default history allow-nest)
+
+However, the use of non-keyword args is deprecated.

+(defvar helm-help-message
+ "* Helm Generic Help
+** Basics
+
+To navigate in this Help buffer see [[Helm help][here]].
+
+Helm narrows down the list of candidates as you type a filter pattern see [[Matching in Helm][Matching in Helm]].
+
+Helm accepts multiple space-separated patterns, each pattern can be negated with \"!\".
+
+Helm also supports fuzzy matching in some places when specified, you will find
+several variables to enable fuzzy matching in diverse [[Helm sources][sources]],
+see [[https://github.com/emacs-helm/helm/wiki/Fuzzy-matching][fuzzy-matching]] in helm-wiki for more infos.
+
+Helm generally uses familiar Emacs keys to navigate the list.
+Here follow some of the less obvious bindings:
+
+- `\\<helm-map>\\[helm-maybe-exit-minibuffer]' selects the candidate from the list, executes the default action
+upon exiting the Helm session.
+
+- `\\<helm-map>\\[helm-execute-persistent-action]' executes the default action but without exiting the Helm session.
+Not all sources support this.
+
+- `\\<helm-map>\\[helm-select-action]' displays a list of actions available on current candidate or all marked candidates.
+The default binding <tab> is ordinarily used for completion, but that would be
+redundant since Helm completes upon every character entered in the prompt.
+See [[https://github.com/emacs-helm/helm/wiki#helm-completion-vs-emacs-completion][Helm wiki]].
+
+Note: In addition to the default actions list, additional actions appear
+depending of the type of the selected candidate(s). They are called filtered
+actions.
+
+** Helm sources
+
+Helm uses what's called sources to provide different kinds of completions, each helm session
+can handle one or more source.
+A source is an alist object which is build from various classes, see [[Writing your own Helm sources][here]]
+and [[https://github.com/emacs-helm/helm/wiki/Developing#creating-a-source][Helm wiki]] for more infos.
+
+*** Configure sources
+
+You will find in helm sources already built and bound to a
+variable called generally `helm-source-<something>', in this case
+it is an alist and you can change the attributes (keys) values
+using `helm-attrset' function in your config, of course you have
+to ensure before calling `helm-attrset' that the file containing
+source is loaded with e.g. `with-eval-after-load'. Of course you
+can also completely redefine the source but this is generally not
+elegant as it duplicate for its most part code already defined in
+Helm.
+
+You will find also sources that are not built and even not bound
+to any variables because they are rebuilded at each start of helm
+session. In this case you can add a defmethod called
+`helm-setup-user-source' to your config:
+
+#+begin_src elisp
+
+ (defmethod helm-setup-user-source ((source helm-moccur-class))
+ (setf (slot-value source 'follow) -1))
+
+#+end_src
+
+See [[https://github.com/emacs-helm/helm/wiki/FAQ#why-is-a-customizable-helm-source-nil][here]] for more infos,
+and for more complex examples of configuration [[https://github.com/thierryvolpiatto/emacs-tv-config/blob/master/init-helm.el#L340][here]].
+
+** Matching in Helm
+
+All what you write in minibuffer is interpreted as a regexp or
+multiple regexps if separated by a space. This is true for most
+sources unless developer of source have disabled it or have choosen to
+use fuzzy matching. Even if a source have fuzzy matching enabled,
+helm will switch to multi match as soon as it detect a space in
+pattern, it may also switch to multi match as well if pattern starts
+with a \"^\" beginning of line sign, in those cases each pattern
+separated with space should be a regexp and not a fuzzy pattern. When
+using multi match patterns, each pattern starting with \"!\" is
+interpreted as a negation i.e. match everything but this.
+
+** Helm mode
+
+`helm-mode' toggles Helm completion in native Emacs functions,
+so when you turn `helm-mode' on, commands like `switch-to-buffer' will use
+Helm completion instead of the usual Emacs completion buffer.
+
+*** What gets or does not get \"helmized\" when `helm-mode' is enabled?
+
+Helm provides generic completion on all Emacs functions using `completing-read',
+`completion-in-region' and their derivatives, e.g. `read-file-name'. Helm
+exposes a user variable to control which function to use for a specific Emacs
+command: `helm-completing-read-handlers-alist'. If the function for a specific
+command is nil, it turns off Helm completion. See the variable documentation
+for more infos.
+
+*** Helm functions vs helmized Emacs functions
+
+While there are Helm functions that perform the same completion as other
+helmized Emacs functions, e.g. `switch-to-buffer' and `helm-buffers-list', the
+native Helm functions like `helm-buffers-list' can receive new features, the
+allow marking candidates, they have several actions, etc. Whereas the helmized
+Emacs functions only have Helm completion, one action and no more then Emacs can
+provide for this function. This is the intended behavior.
+
+Generally you are better off using the native Helm command
+than the helmized Emacs equivalent.
+
+*** Completion behavior with Helm and completion-at-point
+
+Helm is NOT completing dynamically, that's mean that when you are
+completing some text at point, completion is done against this
+text and subsequent characters you add AFTER this text, this
+allow you to use matching methods provided by Helm, that is multi
+matching or fuzzy matching (see [[Matching in Helm][Matching in Helm]]).
+
+Completion is not done dynamically (against `helm-pattern')
+because backend functions (i.e. `competion-at-point-functions')
+are not aware of the Helm matching methods.
+
+By behaving like this, the benefit is that you can fully use Helm
+matching methods but you can't start a full completion against a
+prefix different than the initial text you have at point, Helm
+warn you against this by colorizing the initial input and send an
+user-error message when trying to delete backward text beyond
+this limit at first hit on DEL and on second hit on DEL within a
+short delay (1s) quit Helm and delete-backward char in
+current-buffer.
+
+** Helm help
+
+\\[helm-documentation]: Show all helm documentations concatenated in one org file.
+
+From a Helm session, just hit \\<helm-map>\\[helm-help] to have the
+documentation for the current source followed by the global Helm documentation.
+
+While in the help buffer, most of the Emacs regular keybindings
+are available; the most important ones are shown in minibuffer.
+However due to the implementation restrictions, no regular Emacs
+keymap is used (it runs in a loop when reading the help buffer)
+they are hardcoded and not modifiable.
+
+The hard-coded documentation bindings are:
+
+| Key | Alternative keys | Command |
+|-----------+------------------+---------------------|
+| C-v | Space next | Scroll up |
+| M-v | b prior | Scroll down |
+| C-s | | Isearch forward |
+| C-r | | Isearch backward |
+| C-a | | Beginning of line |
+| C-e | | End of line |
+| C-f | right | Forward char |
+| C-b | left | Backward char |
+| C-n | down | Next line |
+| C-p | up | Previous line |
+| M-a | | Backward sentence |
+| M-e | | Forward sentence |
+| M-f | | Forward word |
+| M-b | | Backward word |
+| M-> | | End of buffer |
+| M-< | | Beginning of buffer |
+| C-<SPACE> | | Toggle mark |
+| RET | | Follow org link |
+| C-% | | Push org mark |
+| C-& | | Goto org mark-ring |
+| TAB | | Org cycle |
+| M-<TAB> | | Toggle visibility |
+| M-w | | Copy region |
+| q | | Quit |
+
+** Customize Helm
+
+Helm provides a lot of user variables for extensive customization.
+From any Helm session, type \\<helm-map>\\[helm-customize-group] to jump to the current source `custom' group.
+Helm also has a special group for faces you can access via `M-x customize-group RET helm-faces'.
+
+Note: Some sources may not have their group set and default to the `helm' group.
+
+** Display Helm in windows and frames
+
+You can display the helm completion buffer in many differents
+window configurations, see the custom interface to discover the
+different windows configurations available (See [[Customize Helm][Customize Helm]] to jump to custom interface).
+When using Emacs in a graphic display (i.e. not in a terminal) you can as
+well display your helm buffers in separated frames globally for
+all helm commands or separately for specific helm commands.
+See [[https://github.com/emacs-helm/helm/wiki/frame][helm wiki]] for more infos.
+
+** Helm's basic operations and default key bindings
+
+| Key | Alternative Keys | Command |
+|---------+------------------+----------------------------------------------------------------------|
+| C-p | Up | Previous line |
+| C-n | Down | Next line |
+| M-v | prior | Previous page |
+| C-v | next | Next page |
+| Enter | | Execute first (default) action / Select [1] |
+| M-< | | First line |
+| M-> | | Last line |
+| C-M-S-v | M-prior, C-M-y | Previous page (other-window) |
+| C-M-v | M-next | Next page (other-window) |
+| Tab | C-i | Show action list |
+| M-o | | Previous source |
+| C-o | | Next source |
+| C-k | | Delete pattern (with prefix arg delete from point to end or all [2]) |
+| C-j | | Persistent action (Execute and keep Helm session) |
+
+\[1] Behavior may change depending context in some source e.g. `helm-find-files'.
+
+\[2] Delete from point to end or all depending on the value of
+`helm-delete-minibuffer-contents-from-point'.
+
+** Action transformers
+
+You may be surprized to see you actions list changing depending of context, this
+happen when a source have an action transformer function which check the current
+candidate selectioned and add specific actions for this candidate.
+
+** Shortcuts for n-th first actions
+
+f1-f12: Execute n-th action where n is 1 to 12.
+
+** Shortcuts for executing the default action on the n-th candidate
+
+Helm does not display line numbers by default, with Emacs-26+
+you can enable it permanently in all helm buffers with:
+
+ (add-hook 'helm-after-initialize-hook 'helm-init-relative-display-line-numbers)
+
+You can also toggle line numbers with \\<helm-map>\\[helm-display-line-numbers-mode] in current helm buffer.
+
+Of course when enabling `global-display-line-numbers-mode' helm buffers will have line numbers as well.
+\(don't forget to customize `display-line-numbers-type' to relative).
+
+In Emacs versions < to 26 you will have to use [[https://github.com/coldnew/linum-relative][linum-relative]] package
+and `helm-linum-relative-mode'.
+
+Then when line numbers are enabled with one of the methods above
+the following keys are available([1]):
+
+C-x <n>: Execute default action on the n-th candidate before currently selected candidate.
+
+C-c <n>: Execute default action on the n-th candidate after current selected candidate.
+
+\"n\" is limited to 1-9. For larger jumps use other navigation keys.
+
+\[1] Note that the keybindings are always available even if line numbers are not displayed,
+they are just useless in this case.
+
+** Mouse control in Helm
+
+A basic support for the mouse is provided when the user sets `helm-allow-mouse' to non-nil.
+
+- mouse-1 selects the candidate.
+- mouse-2 executes the default action on selected candidate.
+- mouse-3 pops up the action menu.
+
+Note: When mouse control is enabled in Helm, it also lets you click around and lose
+the minibuffer focus: you'll have to click on the Helm buffer or the minibuffer
+to retrieve control of your Helm session.
+
+** Marked candidates
+
+You can mark candidates to execute an action on all of them instead of the
+current selected candidate only. (See bindings below.) Most Helm actions
+operate on marked candidates unless candidate-marking is explicitely forbidden
+for a specific source.
+
+- To mark/unmark a candidate, use \\[helm-toggle-visible-mark]. (See bindings below.)
+With a numeric prefix arg mark ARG candidates forward, if ARG is negative
+mark ARG candidates backward.
+
+- To mark all visible unmarked candidates at once in current source use \\[helm-mark-all].
+With a prefix argument, mark all candidates in all sources.
+
+- To unmark all visible marked candidates at once use \\[helm-unmark-all].
+
+- To mark/unmark all candidates at once use \\[helm-toggle-all-marks].
+With a prefix argument, mark/unmark all candidates in all sources.
+
+Note: When multiple candidates are selected across different sources, only the
+candidates of the current source will be used when executing most actions (as
+different sources can have different actions). Some actions support
+multi-source marking however.
+
+** Follow candidates
+
+When `helm-follow-mode' is on (\\<helm-map>\\[helm-follow-mode] to toggle it),
+moving up and down the Helm session or updating the list of candidates will
+automatically execute the persistent-action as specified for the current source.
+
+If `helm-follow-mode-persistent' is non-nil, the state of the mode will be
+restored for the following Helm sessions.
+
+If you just want to follow candidates occasionally without enabling
+`helm-follow-mode', you can use \\<helm-map>\\[helm-follow-action-forward] or \\[helm-follow-action-backward] instead.
+Conversely, when `helm-follow-mode' is enabled, those commands
+go to previous/next line without executing the persistent action.
+
+** Frequently Used Commands
+
+\\[helm-toggle-resplit-and-swap-windows]\t\tToggle vertical/horizontal split on first hit and swap Helm window on second hit.
+\\[helm-exchange-minibuffer-and-header-line]\t\tExchange minibuffer and header-line.
+\\[helm-quit-and-find-file]\t\tDrop into `helm-find-files'.
+\\[helm-kill-selection-and-quit]\t\tKill display value of candidate and quit (with prefix arg, kill the real value).
+\\[helm-yank-selection]\t\tYank current selection into pattern.
+\\[helm-copy-to-buffer]\t\tCopy selected candidate at point in current buffer.
+\\[helm-follow-mode]\t\tToggle automatic execution of persistent action.
+\\[helm-follow-action-forward]\tRun persistent action then select next line.
+\\[helm-follow-action-backward]\t\tRun persistent action then select previous line.
+\\[helm-refresh]\t\tRecalculate and redisplay candidates.
+\\[helm-toggle-suspend-update]\t\tToggle candidate updates.
+
+** Special yes, no or yes for all answers
+
+You may be prompted in the minibuffer to answer by [y,n,!,q] in some places
+for confirmation.
+
+- y mean yes
+- no mean no
+- ! mean yes for all
+- q mean quit or abort current operation.
+
+When using ! you will not be prompted anymore for the same thing in current operation
+e.g. file deletion, file copy etc...
+
+** Moving in `helm-buffer'
+
+You can move in `helm-buffer' with the usual commands used in Emacs:
+\(\\<helm-map>\\[helm-next-line], \\<helm-map>\\[helm-previous-line], etc. See above basic commands.
+When `helm-buffer' contains more than one source, change source with \\<helm-map>\\[helm-next-source] and \\[helm-previous-source].
+
+Note: When reaching the end of a source, \\<helm-map>\\[helm-next-line] will *not* go to the next source when
+variable `helm-move-to-line-cycle-in-source' is non-nil, so you will have to use \\<helm-map>\\[helm-next-source]
+and \\[helm-previous-source].
+
+** Resume previous session from current Helm session
+
+You can use `C-c n' (`helm-run-cycle-resume') to cycle in resumables sources.
+`C-c n' is a special key set with `helm-define-key-with-subkeys' which, after pressing it, allows you
+to keep cycling with further `n'.
+
+Tip: You can bound the same key in `global-map' to `helm-cycle-resume'
+ with `helm-define-key-with-subkeys' to let you transparently cycle
+ sessions, Helm fired up or not.
+ You can also bind the cycling commands to single key presses (e.g. `S-<f1>') this time
+ with a simple `define-key'. (Note that `S-<f1>' is not available in terminals.)
+
+Note: `helm-define-key-with-subkeys' is available only once Helm is loaded.
+
+You can also use \\<helm-map>\\[helm-resume-previous-session-after-quit] to resume
+the previous session, or \\<helm-map>\\[helm-resume-list-buffers-after-quit]
+to have completion on all resumable buffers.
+
+** Global commands
+
+*** Resume Helm session from outside Helm
+
+\\<global-map>\\[helm-resume] revives the last `helm' session. Binding a key to
+this command will greatly improve `helm' interactivity, e.g. when quitting Helm
+accidentally.
+
+You can call \\<global-map>\\[helm-resume] with a prefix argument to choose
+\(with completion!) which session you'd like to resume. You can also cycle in
+these sources with `helm-cycle-resume' (see above).
+
+** Debugging Helm
+
+Helm exposes the special variable `helm-debug': setting it to non-nil
+will enable Helm logging in a special outline-mode buffer.
+Helm resets the variable to nil at the end of each session.
+
+For convenience, \\<helm-map>\\[helm-enable-or-switch-to-debug]
+allows you to turn on debugging for this session only.
+To avoid accumulating log entries while you are typing patterns, you can use
+\\<helm-map>\\[helm-toggle-suspend-update] to turn off updating. When you
+are ready turn it on again to resume logging.
+
+Once you exit your Helm session you can access the debug buffer with
+`helm-debug-open-last-log'. It is possible to save logs to dated files when
+`helm-debug-root-directory' is set to a valid directory.
+
+Note: Be aware that Helm log buffers grow really fast, so use `helm-debug' only
+when needed.
+
+** Writing your own Helm sources
+
+Writing simple sources for your own usage is easy. When calling the `helm'
+function, the sources are added the :sources slot which can be a symbol or a
+list of sources. Sources can be built with different EIEIO classes depending
+what you want to do. To simplify this, several `helm-build-*' macros are
+provided. Below, simple examples to start with.
+
+We will not go further here, see [[https://github.com/emacs-helm/helm/wiki/Developing][Helm wiki]] and the source
+code for more information and more complex examples.
+
+#+begin_src elisp
+
+ ;; Candidates are stored in a list.
+ (helm :sources (helm-build-sync-source \"test\"
+ ;; A function can be used as well
+ ;; to provide candidates.
+ :candidates '(\"foo\" \"bar\" \"baz\"))
+ :buffer \"*helm test*\")
+

+
+Keywords supported:
+
+- :sources
+- :input
+- :prompt
+- :resume
+- :preselect
+- :buffer
+- :keymap
+- :default
+- :history
+- :allow-nest
+
+Extra LOCAL-VARS keywords are supported, see the \"** Other
+keywords\" section below.
+
+Basic keywords are the following:
+
+*** :sources
+
+One of the following:
+
+- List of sources
+- Symbol whose value is a list of sources
+- Alist representing a Helm source.
+ - In this case the source has no name and is referenced in
+ `helm-sources' as a whole alist.
+
+*** :input
+
+Initial input of minibuffer (temporary value of `helm-pattern')
+
+*** :prompt
+
+Minibuffer prompt. Default value is `helm--prompt'.
+
+*** :resume
+
+If t, allow resumption of the previous session of this Helm
+command, skipping initialization.
+
+If 'noresume, this instance of `helm' cannot be resumed.
+
+*** :preselect
+
+Initially selected candidate (string or regexp).
+
+*** :buffer
+
+Buffer name for this Helm session. `helm-buffer' will take this value.
+
+*** :keymap
+
+\[Obsolete]
+
+Keymap used at the start of this Helm session.
+
+It is overridden by keymaps specified in sources, and is kept
+only for backward compatibility.
+
+Keymaps should be specified in sources using the :keymap slot
+instead. See `helm-source'.
+
+This keymap is not restored by `helm-resume'.
+
+*** :default
+
+Default value inserted into the minibuffer \ with
+\\<minibuffer-local-map>\\[next-history-element].
+
+It can be a string or a list of strings, in this case
+\\<minibuffer-local-map>\\[next-history-element] cycles through
+the list items, starting with the first.
+
+If nil, `thing-at-point' is used.
+
+If `helm--maybe-use-default-as-input' is non-`nil', display is
+updated using this value, unless :input is specified, in which
+case that value is used instead.
+
+*** :history
+
+Minibuffer input, by default, is pushed to `minibuffer-history'.
+
+When an argument HISTORY is provided, input is pushed to
+HISTORY. HISTORY should be a valid symbol.
+
+*** :allow-nest
+
+Allow running this Helm command in a running Helm session.
+
+** Other keywords
+
+Other keywords are interpreted as local variables of this Helm
+session. The `helm-' prefix can be omitted. For example,
+
+\(helm :sources 'helm-source-buffers-list
+ :buffer \"*helm buffers*\"
+ :candidate-number-limit 10\)
+
+starts a Helm session with the variable
+`helm-candidate-number-limit' set to 10.
+
+** Backward compatibility
+
+For backward compatibility, positional parameters are
+supported:
+
+\(helm sources input prompt resume preselect
+ buffer keymap default history allow-nest\)
+
+However, the use of non-keyword args is deprecated.

+FASTER than string list processing and is the Emacs way.
+
+The init function writes all candidates to a newly-created
+candidate buffer. The candidates buffer is created or specified
+by `helm-candidate-buffer'. Candidates are stored in a line.
+
+The candidates function narrows all candidates, IOW creates a
+subset of candidates dynamically.
+
+Class `helm-source-in-buffer' is implemented with three attributes:
+
+ (candidates . helm-candidates-in-buffer)
+ (volatile)
+ (match identity)
+
+The volatile attribute is needed because `helm-candidates-in-buffer'
+creates candidates dynamically and need to be called every
+time `helm-pattern' changes.
+
+Because `helm-candidates-in-buffer' plays the role of `match' attribute
+function, specifying `(match identity)' makes the source slightly faster.
+
+However if source contains `match-part' attribute, match is computed only
+on part of candidate returned by the call of function provided by this attribute.
+The function should have one arg, candidate, and return only
+a specific part of candidate.
+
+To customize `helm-candidates-in-buffer' behavior,
+use `search', `get-line' and `match-part' attributes."

+
+This function is still in public API only for backward compatibility,

+- global (a symbol)

+ may mangle your buffer depending what you write in your init(s)

-;;; Commentary:
-;; This package is a replacement of `describe-bindings' for Helm.
-
-;; Usage:
-;;
-;; You can use this package independently from Helm - in particular,
-;; you don't need to turn on `helm-mode' to be able to use this. Helm
-;; just needs to be installed.
-;;
-;; Add followings on your .emacs.
-;;
-;; (require 'helm-descbinds)
-;; (helm-descbinds-mode)
-;;
-;; or use customize to set `helm-descbinds-mode' to t.
-;;
-;; Now, `describe-bindings' is replaced with `helm-descbinds'. As
-;; usual, type `C-h b', or any incomplete key sequence plus C-h , to
-;; run `helm-descbinds'. The bindings are presented in a similar way
-;; as `describe-bindings ' does, but you can use completion to find
-;; the command you searched for and execute it, or view it's
-;; documentation.
-;;
-;; In the Helm completions buffer, you match key bindings with the
-;; Helm interface:
-;;
-;; - When you type RET, the selected candidate command is executed.
-;;
-;; - When you hit RET on a prefix key, the candidates are narrowed to
-;; this prefix
-;;
-;; - When you type TAB, you can select "Execute", "Describe" or "Find
-;; Function" by the menu (i.e. these are the available "actions"
-;; and are of course also available via their usual shortcuts).
-;;
-;; - When you type C-z (aka "persistent action"), the selected
-;; command is described without quitting Helm.

-;;; Commentary:
-;;
-;; This library provides easy project management and navigation. The
-;; concept of a project is pretty basic - just a folder containing
-;; special file. Currently git, mercurial and bazaar repos are
-;; considered projects by default. If you want to mark a folder
-;; manually as a project just create an empty .projectile file in
-;; it. See the README for more details.

+;; This library provides easy project management and navigation. The
+;; concept of a project is pretty basic - just a folder containing
+;; special file. Currently git, mercurial and bazaar repos are
+;; considered projects by default. If you want to mark a folder
+;; manually as a project just create an empty .projectile file in
+;; it. See the README for more details.
