This section describes the keymaps, commands and user options used in the minibuffer to do completion. The description refers to the situation when Partial Completion mode is disabled (as it is by default). When enabled, this minor mode uses its own alternatives to some of the commands described below. Voir (emacs)Completion Options section `Completion Options' dans The GNU Emacs Manual, for a short description of Partial Completion mode.
The value of this variable is the collection used for completion in the
minibuffer. This is the global variable that contains what
completing-read passes to try-completion. It is used by
minibuffer completion commands such as minibuffer-complete-word.
This variable's value is the predicate that completing-read passes to
try-completion. The variable is also used by the other minibuffer
completion functions.
When the value of this variable is non-nil, Emacs asks for
confirmation of a completion before exiting the minibuffer.
completing-read binds this variable, and the function
minibuffer-complete-and-exit checks the value before exiting.
This function completes the minibuffer contents by at most a single word.
Even if the minibuffer contents have only one completion,
minibuffer-complete-word does not add any characters beyond the first
character that is not a word constituent. @xref{Syntax Tables}.
This function completes the minibuffer contents as far as possible.
This function completes the minibuffer contents, and exits if confirmation
is not required, i.e., if minibuffer-completion-confirm is
nil. If confirmation is required, it is given by repeating
this command immediately—the command is programmed to work without
confirmation when run twice in succession.
This function creates a list of the possible completions of the current
minibuffer contents. It works by calling all-completions using the
value of the variable minibuffer-completion-table as the
collection argument, and the value of
minibuffer-completion-predicate as the predicate argument. The
list of completions is displayed as text in a buffer named
‘*Completions*’.
This function displays completions to the stream in
standard-output, usually a buffer. (Voir la section Reading and Printing Lisp Objects, for more
information about streams.) The argument completions is normally a
list of completions just returned by all-completions, but it does not
have to be. Each element may be a symbol or a string, either of which is
simply printed. It can also be a list of two strings, which is printed as
if the strings were concatenated. The first of the two strings is the
actual completion, the second string serves as annotation.
The argument common-substring is the prefix that is common to all the
completions. With normal Emacs completion, it is usually the same as the
string that was completed. display-completion-list uses this to
highlight text in the completion list for better visual feedback. This is
not needed in the minibuffer; for minibuffer completion, you can pass
nil.
This function is called by minibuffer-completion-help. The most
common way to use it is together with with-output-to-temp-buffer,
like this:
(with-output-to-temp-buffer "*Completions*"
(display-completion-list
(all-completions (buffer-string) my-alist)
(buffer-string)))
|
If this variable is non-nil, the completion commands automatically
display a list of possible completions whenever nothing can be completed
because the next character is not uniquely determined.
completing-read uses this value as the local keymap when an exact
match of one of the completions is not required. By default, this keymap
makes the following bindings:
minibuffer-completion-help
minibuffer-complete-word
minibuffer-complete
with other characters bound as in minibuffer-local-map
(voir Definition of minibuffer-local-map).
completing-read uses this value as the local keymap when an exact
match of one of the completions is required. Therefore, no keys are bound
to exit-minibuffer, the command that exits the minibuffer
unconditionally. By default, this keymap makes the following bindings:
minibuffer-completion-help
minibuffer-complete-word
minibuffer-complete
minibuffer-complete-and-exit
minibuffer-complete-and-exit
with other characters bound as in minibuffer-local-map.
This is like minibuffer-local-completion-map except that it does not
bind <SPC>. This keymap is used by the function read-file-name.
This is like minibuffer-local-must-match-map except that it does not
bind <SPC>. This keymap is used by the function read-file-name.
