+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'
+source in *buffers* buffer and set variable `helm-candidate-number-limit'

+Read a string in the minibuffer, with helm completion.
+
+It is helm `completing-read' equivalent.

+- PROMPT is the prompt name to use.
+
+- 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.
+
+- 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.
+
+- 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 (enabled by default).
+
+- SORT: A predicate to give to `sort' e.g `string-lessp'.
+
+- FC-TRANSFORMER: A `filtered-candidate-transformer' function.
+
+- 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-candidates-in-buffer' which is much faster.
+ Argument VOLATILE have no effect when CANDIDATES-IN-BUFFER is non--nil.

+(defcustom helm-grep-default-command
+ "grep --color=never -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 --no-group --no-color %e %p %f\"
+ helm-grep-default-recurse-command \"ack-grep -H --no-group --no-color %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).
+
+To enable ANSI in grep it is a little more difficult:
+ 1) Modify env var
+ \(setenv \"GREP_COLORS\" \"ms=01;31:mc=01;31:sl=01;37:cx=:fn=35:ln=32:bn=32:se=36\")
+ 2) Add the option \"--color=always\".
+
+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)."

+ "\n* Helm Buffer\n
+
+** Helm buffers 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.
+

+ "\n* Helm Find Files\n
+
+** Helm find files tips:
+\n*** 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 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.
+
+*** 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.
+ 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'.
+ 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.

+** Helm grep tips:\n
+*** 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 grep-mode buffer, see commands below.
+
+*** Important:\n
+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 Moccur tips:
+
+*** 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.
+
+*** 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
+Just hit `g' to update your buffer.
+
+*** Edit a saved buffer
+
+To do so you have to 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.
+
+Tip: Use the excellent iedit https://github.com/tsdh/iedit
+to modify occurences in your buffer.

+(helm-document-attribute 'candidates "mandatory if candidates-in-buffer attribute is not provided"

+
+ The list must be a list whose members are strings, symbols
+ or (DISPLAY . REAL) pairs.
+
+ In case of (DISPLAY . REAL) pairs, the DISPLAY string is shown
+ in the Helm buffer, but the REAL one is used as action
+ argument when the candidate is selected. This allows a more
+ readable presentation for candidates which would otherwise be,
+ for example, too long or have a common part shared with other
+ candidates which can be safely replaced with an abbreviated
+ string for display purposes.
+
+ Note that if the (DISPLAY . REAL) form is used then pattern
+ matching is done on the displayed string, not on the real
+ value.
+
+ If the candidates have to be retrieved asynchronously (for
+ example, by an external command which takes a while to run)

+ asynchronously and return the associated process object.
+ Helm will take care of managing the process (receiving the
+ output from it, killing it if necessary, etc.). The process
+ should return candidates matching the current pattern (see

+ This attribute allows the source to override the default
+ pattern matching based on `string-match'. It can be used, for
+ example, to implement a source for file names and do the
+ pattern matching on the basename of files, since it's more
+ likely one is typing part of the basename when searching for a
+ file, instead of some string anywhere else in its path.
+
+ If the list contains more than one function then the list of
+ matching candidates from the source is constructed by appending
+ the results after invoking the first function on all the

+ will be used for the actual completion. If it is a list of
+ functions, it calls each function sequentially.
+
+ This can be used to transform or remove items from the list of

+ is run only once, it is run every time the input pattern is
+ changed.
+
+ It can be used to transform the candidate list dynamically, for
+ example, based on the current pattern.
+
+ In some cases it may also be more efficent to perform candidate
+ transformation here, instead of with `candidate-transformer'
+ even if this transformation is done every time the pattern is
+ changed. For example, if a candidate set is very large then
+ `candidate-transformer' transforms every candidate while only
+ some of them will actually be dislpayed due to the limit
+ imposed by `helm-candidate-number-limit'.
+
+ Note that `candidates' and `candidate-transformer' is run

+
+- 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.
+
+- 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.
+
+- 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 \(enabled by default\).
+
+- SORT: A predicate to give to `sort' e.g `string-lessp'.
+
+- FC-TRANSFORMER: A `filtered-candidate-transformer' function.
+
+- 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-candidates-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

+Extra LOCAL-VARS keywords are supported, see below.
+
+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'
+source in *buffers* buffer and set variable `helm-candidate-number-limit'

++===============================================================+
+| The new way of making and narrowing candidates: Using buffers |
++===============================================================+
+
+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."
