This section describes the keymaps, commands and user options used in the minibuffer to do completion.
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
(see Text from Minibuffer).
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.
The value of this variable is the alist or obarray 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.
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. See 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.
When the value of this variable is non-nil, SXEmacs asks for
confirmation of a completion before exiting the minibuffer. The
function minibuffer-complete-and-exit checks the value of this
variable before it exits.
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. (See Read and Print, 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, or a list of two strings, which is printed
as if the strings were concatenated.
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)))
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.
