When completion is done on file names, certain file names are usually
ignored. The variable
completion-ignored-extensions contains a
list of strings; a file whose name ends in any of those strings is
ignored as a possible completion. The standard value of this variable
has several elements including
"~". The effect is that, for example, `foo' can
complete to `foo.c' even though `foo.o' exists as well.
However, if all the possible completions end in "ignored"
strings, then they are not ignored. Ignored extensions do not apply to
lists of completions--those always mention all possible completions.
Normally, a completion command that finds the next character is undetermined
automatically displays a list of all possible completions. If the variable
completion-auto-help is set to
nil, this does not happen,
and you must type ? to display the possible completions.
complete library implements a more powerful kind of
completion that can complete multiple words at a time. For example, it
can complete the command name abbreviation
print-buffer, because no other command starts with two words
whose initials are `p' and `b'. To use this library, put
(load "complete") in your `~/.emacs' file (see section The Init File, `~/.emacs').
Icomplete mode presents a constantly-updated display that tells you what completions are available for the text you've entered so far. The command to enable or disable this minor mode is M-x icomplete-mode.
