"Alist of handlers to replace `completing-read', `read-file-name' in `helm-mode'.
|
|
|
|
|
|
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 an helm function that take 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.
|
|
|
|
|
|
This function prefix name must start by \"helm\".
|
|
|
|
|
|
|
|
|
|
|
|
See `helm-completing-read-symbols' for example.
|
|
|
|
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
e.g If you want to disable helm completion for `describe-function':
|
|
|
|
|
|
\(describe-function . nil\).
|
|
|
|
|
|
|
|
|
|
|
|
Ido is also supported, you can use `ido-completing-read' and
|
|
|
|
|
|
`ido-read-file-name' as value of an entry or just 'ido.
|
|
|
|
|
|
e.g ido completion for `find-file':
|
|
|
|
|
|
\(find-file . ido\)
|
|
|
|
|
|
same as
|
|
|
|
|
|
\(find-file . ido-read-file-name\)
|
|
|
|
|
|
Note that you don't need to enable `ido-mode' for this to work."

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:
|
|
|
|
|
|

|
|
|
|
|
|

- INITIAL-INPUT: Same as input arg in `helm'.
|
|
|

|
|
|
- PRESELECT: See preselect arg of `helm'.
|
|
|
|
|
|
|
|
|
|
|
|
- DEFAULT: This option is used only for compatibility with regular
|
|
|
|

|
|
|
|
|
|

|
- BUFFER: Name of helm-buffer.
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
- FUZZY: Enable fuzzy matching.
|
|
|
|
|

|
|
|
|
|
|
- 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.
|

|
|
|
|
|
|
minibuffer input from HISTORY is present.
|
|
|
|
|

|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
- PERSISTENT-HELP: A string to document PERSISTENT-ACTION.
|
|
|

|
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'

|
|
|
|
|
|
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.

|
|
|

|
|
|
|
|
|
|
|
|
|
|
|
- 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.
|
|
|
|
|
|
|
2016-08-18 20:01:20 +00:00
|
|
|
|
- MATCH-PART: Allow matching only one part of candidate.
|
|
|
|
|
|
See match-part documentation 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
|
|
|
|

`helm-comp-read' invocation, the value of `current-prefix-arg' will be used.

All functions in Emacs that use `completing-read'
|
|
|
|
|
|
or `read-file-name' and friends will use helm interface
|
|
|
|
|
|
when this mode is turned on.
|
|
|
|
|
|
However you can modify this behavior for functions of your choice
|
|
|
|
|
|
with `helm-completing-read-handlers-alist'.
|
|
|
|
|
|
|
|
|
|
|
|
Called with a positive arg, turn on unconditionally, with a
|
|
|
|
|
|
negative arg turn off.
|
|
|
|
|
|
You can turn it on with `helm-mode'.
|
|
|
|
|
|
|
|
|
|
|
|
Some crap emacs functions may not be supported,
|
|
|
|
|
|
e.g `ffap-alternate-file' and maybe others
|
|
|
|
|
|
You can add such functions to `helm-completing-read-handlers-alist'
|
|
|
|
|
|
with a nil value.
