+(defcustom helm-grep-default-command
+ "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 --smart-case --no-group %e %p %f\"
+ helm-grep-default-recurse-command \"ack-grep -H --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).
+
+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 name of major-mode (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\" will list all buffers but the ones in lisp-mode, sh-mode and
+fundamental-mode.
+
+Enter then a space and a pattern to narrow down to buffers matching this pattern.
+
+**** Search inside buffers
+
+If you enter a space and a pattern prefixed by \"@\" helm will search for text matching
+this pattern INSIDE the buffer (i.e not in the name of buffer).
+NOTE that if you enter your pattern prefixed with \"@\" but escaped, helm will search a buffer
+matching \"@pattern\" but will not search inside.
+
+**** Search by directory name
+
+If you prefix the beginning of pattern with \"/\" the match will occur on directory name
+of buffer, it is interesting to narrow down to one directory for example, subsequent string
+entered after a space will match on buffer-name only.
+Note that negation is not supported for matching on buffer-file-name.
+You can specify more than one directory starting from helm v1.6.8
+
+**** Fuzzy matching
+
+Note that if `helm-buffers-fuzzy-matching' is non--nil you will have
+fuzzy matching on buffer names (not on directory name matching and major-mode though).
+A pattern starting with \"^\" will disable fuzzy matching and will match by exact regexp.
+
+**** Examples
+
+if I enter in pattern prompt:
+
+ \"*lisp ^helm @moc\"
+
+helm will narrow down the list by selecting only buffers that are in lisp mode, start by helm
+and match \"moc\" in their contents.
+
+if I enter in pattern prompt:
+
+ \"*lisp ^helm moc\"
+
+Notice there is no \"@\" this time
+helm will look for lisp mode buffers starting by \"helm\" and have \"moc\" in their name.
+
+if I enter in pattern prompt:
+
+ \"*!lisp !helm\"
+
+helm will narrow down to buffers that are not in \"lisp\" mode and that do not match \"helm\"
+
+if I enter in pattern prompt:
+
+ /helm/ w3
+
+helm will narrow 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 for your buffer in a list.
+This list is customizable, see `helm-buffers-favorite-modes'.
+
+*** Killing buffers
+
+You have a command to kill buffer(s) and quit emacs and a command to kill buffers one by one
+\(no marked\) without quitting helm.
+
+You can run this persistent kill buffer command either with the regular
+`helm-execute-persistent-action' called with a prefix arg (C-u C-j) or with its specific command
+`helm-buffer-run-kill-persistent' see binding below.
+
+*** Meaning of colors and prefixes for buffers
+
+Remote buffers are prefixed with '@'.
+Red => Buffer have its file modified on disk by an external process.
+Indianred2 => Buffer exists but its file have been deleted.
+Orange => Buffer is modified and its file not saved to disk.
+Italic => A non--file 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 `C-j' (persistent action) on a directory to go down one level
+
+On a symlinked directory a prefix arg will allow expanding to its true name.
+
+**** Use `C-l' on a directory to go up one level
+
+**** Use `C-r' to walk back the resulting tree of all the `C-l' you did
+
+Note: The tree is reinitialized each time you enter a new tree with `C-j'
+or by entering some pattern in prompt.
+
+*** Find file at point
+
+Helm is using `ffap' partially or completely to find file at point
+depending on value of `helm-ff-guess-ffap-filenames'.
+You can use full `ffap' by setting this to non-nil (annoying).
+Default value is nil which make `ffap' working partially.
+
+**** Find file at number line
+
+With something like this at point:
+
+ ~/elisp/helm/helm.el:1234
+
+Helm will find this file at line number 1234.
+
+**** Find url at point
+
+When an url is found at point, helm expand to that url only.
+Pressing RET jump to that url using `browse-url-browser-function'.
+
+**** Find mail at point
+
+When a mail address is found at point helm expand to this email address
+prefixed by \"mailto:\". Pressing RET open a message buffer with this mail
+address.
+
+*** Quick pattern expansion
+
+**** Enter `~/' at end of pattern to quickly reach home directory
+
+**** Enter `/' at end of pattern to quickly reach root of your file system
+
+**** Enter `./' at end of pattern to quickly reach `default-directory' (initial start of session)
+
+If you are already in `default-directory' this will move cursor on top.
+
+**** Enter `../' at end of pattern will reach upper directory, moving cursor on top
+
+NOTE: This is different to using `C-l' in that `C-l' don't move cursor on top but stay on previous
+subdir name.
+
+**** Enter any environment var (e.g. `$HOME') at end of pattern, it will be expanded
+
+**** You can yank any valid filename after pattern, it will be expanded
+
+*** Helm find files is fuzzy matching (start on third char entered)
+
+e.g. \"fob\" or \"fbr\" will complete \"foobar\"
+but \"fb\" will wait for a third char for completing.
+
+*** Use `C-u C-j' to watch an image or `C-<down>'
+
+*** `C-j' on a filename will expand in helm-buffer to this filename
+
+Second hit on `C-j' will display buffer filename.
+Third hit on `C-j' will kill buffer filename.
+NOTE: `C-u C-j' will display buffer directly.
+
+*** To browse images directories turn on `helm-follow-mode' and navigate with arrow keys
+
+You can also use `helm-follow-action-forward' and `helm-follow-action-backward'
+\(`C-<down' and `C-<left>').
+
+*** You can turn off/on (toggle) autoupdate completion at any moment with `C-DEL'
+
+It is useful when auto completion is enabled and when trying to create a new file
+or directory you want to prevent helm trying to complete what you are writing.
+NOTE: On a terminal C-<backspace> may not work, use in this case C-c <backspace>.
+
+*** You can create a new directory and a new file at the same time
+
+Just write the path in prompt and press `<RET>'.
+e.g. You can create \"~/new/newnew/newnewnew/my_newfile.txt\".
+
+*** To create a new directory, add a \"/\" at end of new name and press <RET>
+
+*** To create a new file just write the filename not ending with \"/\"
+
+*** Recursive search from helm find files
+
+**** You can use helm browse project (see binding below)
+
+- With no prefix arg
+ If your current directory is under version control
+ with one of git or hg and you have installed helm-ls-git and/or helm-ls-hg
+ https://github.com/emacs-helm/helm-ls-git.git
+ https://github.com/emacs-helm/helm-ls-hg
+ you will see all your files under version control, otherwise
+ you will be back to helm-find-files.
+- With one prefix arg
+ You will see all the files under this directory
+ and other subdirectories (recursion) and this list of files will be cached.
+- With two prefix args
+ same but the cache will be refreshed.
+
+**** You can start a recursive search with Locate of Find (See commands below)
+
+With Locate you can use a local db with a prefix arg. If the localdb doesn't already
+exists, you will be prompted for its creation, if it exists and you want to refresh it,
+give two prefix args.
+
+*** Insert filename at point or complete filename at point
+
+On insertion (no completion, i.e nothing at point):
+
+- `C-c i' => insert absolute file name.
+- `C-u C-c i' => insert abbreviate file name.
+- `C-u C-u C-c i' => insert relative file name.
+
+On completion:
+
+- target starts by ~/ => insert abbreviate file name.
+- target starts by / or [a-z]:/ => insert full path.
+- otherwise => insert relative file name.
+
+*** Using wildcard to select multiple files
+
+Use of wilcard is supported to give a set of files to an action:
+
+e.g. You can copy all the files with \".el\" extension by using \"*.el\"
+and then run your copy action.
+
+You can do the same but with \"**.el\" (note the two stars),
+this will select recursively all \".el\" files under current directory.
+
+NOTE: When using an action that involve an external backend (e.g. grep), using \"**\"
+is not advised (even if it works fine) because it will be slower to select all your files,
+you have better time letting the backend doing 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.
+
+This feature (\"**\") is activated by default with the option `helm-file-globstar'.
+The directory selection with \"**foo/\" like bash shopt globstar option is not supported yet.
+
+*** Copying renaming asynchronously
+
+If you use async library (if you have installed helm from MELPA you do) you can enable
+async for copying/renaming etc... your files by enabling `dired-async-mode'.
+
+Note that even when async is enabled, running a copy/rename action with a prefix arg
+will execute action synchronously, it will follow also the first file of the marked files
+in its destination directory.
+
+*** Bookmark your `helm-find-files' session
+
+You can bookmark your `helm-find-files' session with `C-x r m'.
+You can retrieve later these bookmarks easily by using M-x helm-filtered-bookmarks
+or from the current `helm-find-files' session just hitting `C-x r b'.
+
+*** Run Gid from `helm-find-files'
+
+You can navigate to a project containing an ID file created with the `mkid'
+command from id-utils, and run the `gid' command which will use the symbol at point
+in `helm-current-buffer' as default.

+(defvar helm-read-file-name-help-message
+ "* Helm read file name
+
+** Tips
+
+If you are here, you are probably using a vanilla command like `find-file'
+helmized by `helm-mode', this is cool, but it is even better for your file
+navigation to use `helm-find-files' which is fully featured.
+
+*** Navigation
+
+**** Enter `~/' at end of pattern to quickly reach home directory
+
+**** Enter `/' at end of pattern to quickly reach root of your file system
+
+**** Enter `./' at end of pattern to quickly reach `default-directory' (initial start of session)
+
+If you are in `default-directory' move cursor on top.
+
+**** Enter `../' at end of pattern will reach upper directory, moving cursor on top
+
+NOTE: This different to using `C-l' in that `C-l' don't move cursor on top but stay on previous
+subdir name.
+
+**** You can complete with partial basename (start on third char entered)
+
+E.g. \"fob\" or \"fbr\" will complete \"foobar\"
+but \"fb\" will wait for a third char for completing.
+
+*** Persistent actions
+
+By default `helm-read-file-name' use the persistent actions of `helm-find-files'
+
+**** Use `C-u C-j' to watch an image
+
+**** `C-j' on a filename will expand in helm-buffer to this filename
+
+Second hit on `C-j' will display buffer filename.
+Third hit on `C-j' will kill buffer filename.
+NOTE: `C-u C-j' will display buffer directly.
+
+**** To browse images directories turn on `helm-follow-mode' and navigate with arrow keys
+
+*** Delete characters backward
+
+When you want to delete backward characters, e.g. to create a new file or directory,
+autoupdate may keep updating to an existent directory preventing you from doing so.
+In this 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 C-<backspace> may not work, use in this case C-c <backspace>.
+
+*** Create new directory and files
+
+**** Create a new directory and a new file at the same time
+
+You can create a new directory and a new file at the same time,
+just write the path in prompt and press <RET>.
+E.g. You can create \"~/new/newnew/newnewnew/my_newfile.txt\".
+
+**** To create a new directory, add a \"/\" at end of new name and press <RET>
+
+**** To create a new file just write the filename not ending with \"/\"

+ "* Helm Grep
+
+** Tips
+
+*** You can start grep with a prefix arg to recurse in subdirectories
+
+*** You can use wild card when selecting files (e.g. *.el)
+
+*** You can grep in many differents directories by marking files or wild cards
+
+*** You can save your results in a `helm-grep-mode' buffer, see commands below
+
+Once in this buffer you can use emacs-wgrep to edit your changes.
+
+*** Important
+
+Grepping on remote file will work only with grep, not ack-grep, but it is
+anyway bad supported as tramp doesn't support multiple process running in a
+short delay (less than 5s actually) among other things,
+so I strongly advice hitting `C-!' (i.e suspend process)
+before entering anything in pattern, and hit again `C-!' when
+your regexp is ready to send to remote process, even if helm is handling
+this by delaying each process at 5s.
+Or even better don't use tramp at all and mount your remote file system on SSHFS.
+
+* Helm Gid
+
+** Tips
+
+Helm gid read 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.
+You have access to this command also from `helm-find-files' which allow you to
+navigate to another directory to consult its database.
+
+* Helm AG
+
+** Tips
+
+Helm AG is different from grep or ack-grep in that it works on a directory and not
+a list of files.
+You can ignore files and directories by using a \".agignore\" file, local to directory
+or global when placed in home directory (See AG man page for more infos).
+This file supports same entries as what you will find in `helm-grep-ignored-files' and
+`helm-grep-ignored-directories'.
+As always you can access helm AG from `helm-find-files'.

+*** Matching
+
+Multiple regexp matching is allowed, just enter a space to separate your regexps.
+
+Matching empty lines is supported with the regexp \"^$\", you will get the results
+with only the buffer-name and the line number, you can of course save and edit these
+results (i.e add text to the empty line) .
+
+*** Automatically matching symbol at point
+
+You can match automatically the symbol at point, but keeping
+the minibuffer empty ready to write into.
+This is disabled by default, to enable this you have 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 `C-j' (persistent-action), to do it repetitively
+you can use `C-<up>' and `C-<down>' or enable `helm-follow-mode' with `C-c C-f'.
+
+*** Saving results
+
+Same as with helm-grep, you can save the results with `C-x C-s'.
+Of course if you don't save your results, you can get back your session
+with `helm-resume'.
+
+*** Refreshing the resumed session.
+
+When the buffer(s) where you ran helm-(m)occur have been modified, you will be
+warned of this with the buffer flashing to red, you can refresh the buffer by running
+`C-c C-u'.
+This can be done automatically by customizing `helm-moccur-auto-update-on-resume'.
+
+*** Refreshing a saved buffer
+
+Type `g' to update your buffer.
+
+*** Edit a saved buffer
+
+First, install wgrep https://github.com/mhayashi1120/Emacs-wgrep
+and then:
+
+1) C-c C-p to edit the buffer(s).
+2) C-x C-s to save your changes.

+- 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.
+
+- 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.
+
+Any prefix args passed during `helm-comp-read' invocation will be recorded
+in `helm-current-prefix-arg', otherwise if prefix args were given before
+`helm-comp-read' invocation, the value of `current-prefix-arg' will be used.
+That's mean you can pass prefix args before or after calling a command
+that use `helm-comp-read' See `helm-M-x' for example."

+
+PLIST is a list like (:key1 val1 :key2 val2 ...) or
+\(&optional sources input prompt resume
+ preselect buffer keymap default history).
+
+Basic keywords are the following:
+
+:sources
+
+A list of sources used for this session. It also accepts a
+symbol, interpreted as a variable of a helm source
+i.e (a symbol can be passed instead of a list of sources).
+It also accepts an alist representing a helm source, which is
+detected by (assq 'name ANY-SOURCES).
+NOTE: In this case the source is embedded in the helm command and
+have no symbol name, so it is not reachable from outside.
+It will be referenced in `helm-sources' as a whole alist.
+
+:input
+
+Temporary value of `helm-pattern', ie. initial input of minibuffer.
+
+:prompt
+
+Prompt other than \"pattern: \".
+
+:resume
+
+If t, Resurrect previously instance of `helm'. Skip the initialization.
+If 'noresume, this instance of `helm' cannot be resumed.
+
+:preselect
+
+Initially selected candidate. Specified by exact candidate or a regexp.
+
+:buffer
+
+`helm-buffer' instead of *helm*.
+
+:keymap
+
+`helm-map' for current `helm' session.
+
+:default
+
+A default argument that will be inserted in minibuffer with \\<minibuffer-local-map>\\[next-history-element].
+When nil or not present `thing-at-point' will be used instead.
+If `helm--maybe-use-default-as-input' is non--nil display will be
+updated using :default arg as input unless :input is specified,
+which in this case will take precedence on :default
+This is a string or a list, in this case the car of the list will
+be used as initial default input, but you will be able to cycle in this
+list with \\<minibuffer-local-map>\\[next-history-element].
+
+:history
+
+By default all minibuffer input is pushed to `minibuffer-history',
+if an argument HISTORY is provided, input will be pushed to HISTORY.
+History element should be a symbol.
+
+:allow-nest
+
+Allow running this helm command within a running helm session.
+
+Of course, conventional arguments are supported, the two are same.
+
+\(helm :sources sources :input input :prompt prompt :resume resume
+ :preselect preselect :buffer buffer :keymap keymap :default default
+ :history history)
+
+and
+
+\(helm sources input prompt resume preselect buffer keymap default history)
+
+are the same.
+
+However the use of non keyword args is deprecated and should not be used.
+
+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 \"*buffers*\" :candidate-number-limit 10)
+
+means starting helm session with `helm-source-buffers'

+** Shortcuts For nth Action
+
+f1-12: Execute nth 1 to 12 Action(s).
+
+** Shortcuts for executing Default Action on nth candidate
+
+C-x <n> => execute default action on number <n> candidate before selection.
+C-c <n> => execute default action on number <n> candidate after selection.
+
+Of course this works only on the 9 first and previous candidates.
+
+Helm provides nothing to visualize candidates numbers, up to you to install
+linum-relative package and enable linum-relative in helm..
+
+** Visible Marks
+
+Visible marks store candidate. Some actions uses marked candidates.
+
+** Miscellaneous 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 selection into pattern.
+\\[helm-follow-mode]\t\tToggle automatical execution of persistent action.
+\\[helm-follow-action-forward]\tRun persistent action and goto next line.

+
+PLIST is a list like \(:key1 val1 :key2 val2 ...\) or
+\(&optional sources input prompt resume
+ preselect buffer keymap default history\).
+
+Basic keywords are the following:
+
+\:sources
+
+A list of sources used for this session. It also accepts a
+symbol, interpreted as a variable of a helm source
+i.e (a symbol can be passed instead of a list of sources).
+It also accepts an alist representing a helm source, which is
+detected by \(assq 'name ANY-SOURCES\).
+NOTE: In this case the source is embedded in the helm command and
+have no symbol name, so it is not reachable from outside.
+It will be referenced in `helm-sources' as a whole alist.
+
+\:input
+
+Temporary value of `helm-pattern', ie. initial input of minibuffer.
+
+\:prompt
+
+Prompt other than \"pattern: \".
+
+\:resume
+
+If t, Resurrect previously instance of `helm'. Skip the initialization.
+If 'noresume, this instance of `helm' cannot be resumed.
+
+\:preselect
+
+Initially selected candidate. Specified by exact candidate or a regexp.
+
+\:buffer
+
+`helm-buffer' instead of *helm*.
+
+\:keymap
+
+`helm-map' for current `helm' session.
+
+\:default
+
+A default argument that will be inserted in minibuffer \
+with \\<minibuffer-local-map>\\[next-history-element].
+When nil or not present `thing-at-point' will be used instead.
+If `helm--maybe-use-default-as-input' is non--nil display will be
+updated using :default arg as input unless :input is specified,
+which in this case will take precedence on :default
+This is a string or a list, in this case the car of the list will
+be used as initial default input, but you will be able to cycle in this
+list with \\<minibuffer-local-map>\\[next-history-element].
+
+\:history
+
+By default all minibuffer input is pushed to `minibuffer-history',
+if an argument HISTORY is provided, input will be pushed to HISTORY.
+History element should be a symbol.
+
+\:allow-nest
+
+Allow running this helm command within a running helm session.
+
+Of course, conventional arguments are supported, the two are same.
+
+\(helm :sources sources :input input :prompt prompt :resume resume
+ :preselect preselect :buffer buffer :keymap keymap :default default
+ :history history\)
+
+and
+
+\(helm sources input prompt resume preselect buffer keymap default history\)
+
+are the same.
+
+However the use of non keyword args is deprecated and should not be used.
+
+Other keywords are interpreted as local variables of this helm session.
+The `helm-' prefix can be omitted. For example,
+
+\(helm :sources 'helm-source-buffers-list
+ :buffer \"*buffers*\" :candidate-number-limit 10\)
+
+means starting helm session with `helm-source-buffers'

+ "The top level function used to store candidates in `helm-source-in-buffer'.
+
+Candidates are stored in a buffer generated internally by the function
+`helm-candidate-buffer'. Each candidate must be placed in one line.
+This function is meant to be used in candidates-in-buffer or candidates
+attribute of an helm source. Especially fast for many (1000+) candidates.
+
+The buffer is created and feeded 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))
+
+The usage of the `candidates-in-buffer' is deprecated in favor
+of `helm-source-in-buffer' class.
+
+It is anyway described below and provided for backward compatibility.
+
+By default, `helm' makes candidates by evaluating the
+candidates function, then narrows them by `string-match' for each
+candidate.
+
+But this way is very slow for many candidates. The new way is
+storing all candidates in a buffer and narrowing them by
+`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. It is the task of
+`helm-candidates-in-buffer'. As long as
+`helm-candidate-buffer' is used,`(candidates-in-buffer)' is
+sufficient in most cases.
+
+Note that `(candidates-in-buffer)' is shortcut of three attributes:
+ (candidates . helm-candidates-in-buffer)
+ (volatile)
+ (match identity)
+And `(candidates-in-buffer . func)' is shortcut of three attributes:
+ (candidates . func)
+ (volatile)
+ (match identity)
+The expansion is performed in `helm-get-sources'.
+
+The `candidates-in-buffer' attribute implies the volatile attribute.
+The volatile attribute is needed because `helm-candidates-in-buffer'
+creates candidates dynamically and need to be called everytime
+`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 contain `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."

+
+;;; 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.

-This package is a replacement of `describe-bindings'.
+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.

-;;
-;; 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

+;; 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.
