Subject: RE: how to determine the current table (really) being used for minibuffer completion?
Date: Sat, 26 Sep 2009 07:58:17 -0700 [thread overview]
Message-ID: <D9ED6E70AA84460D84BEFDF42C22D1A5@us.oracle.com> (raw)
In-Reply-To: <jwvbpkyfq0x.fsf-monnier+emacs@gnu.org>
Hypothetical example that might make the request clearer:
(completion-all-completions
STRING 'read-file-name-internal nil (length STRING))
The result returned might be a list of relative file names, or it might be a
list of env vars. A result such as ("CATACOMBS" "CATAPHILE" "CATASTROPHE" . 4)
could be either.
I would like (via Lisp) to know which kind of completion was in fact used
successfully: file-name completion per se or env var completion.
I don't want to analyze STRING (e.g. check for `$') to figure out what might be
the case. (completion-boundaries STRING 'read-file-name-internal nil "") just
gives something like (0 . 0), indicating the whole STRING.
Emacs should be able to tell me directly what the last completion table/function
used was. It should be easy to make this info available somehow, e.g. in a
global variable.
Similarly, for multiple, successive completion types using `completion-styles',
I would like to know which type (style) was in fact successful.
This is the kind of thing I'm talking about.
