ignoring subdirectory in find-file completion

ignoring subdirectory in find-file completion

[Albert Reiner]

Hi,

I am looking for some way to make completion when using find-file
ignore any directory named _darcs; i.e., if I have a directory
structure

    foo/
      _darcs/
        ...
      bar/
        ...

then `M-x find-file f o o / TAB' should complete to `foo/bar/'.

>From the documentation I thought that

    (add-to-list 'completion-ignored-extensions "_darcs")

should do what I want, but that does not seem to be the case.

Any help would be appreciated.

Albert.

The docs for completion-ignored-extensions say:

...Directories are ignored if they match any string in this list which
ends in a slash...

And your "_darcs" doesn't end in a slash...

Thanks for your reply:

But even with the slash I don't get the desired behavior.  Also, the
description seems to indicate that ignored items should end in that
string, but foo_darcs should not be skipped.

BTW, the version here is "GNU Emacs 21.3.1 (i386-redhat-linux-gnu, X
toolkit, Xaw3d scroll bars) of 2005-02-04 on bugs.build.redhat.com".

Thanks again,

Albert.

Sorry, can't do that,

Well, I'll live with that.  Thanks for your help, though, and for
pointing out that support for this isn't built in.

Albert.

IIRC, this feature has a bug in 21.3 (and older versions as well), and
will be only fixed in the next release.  (And even there foo_darcs
will be skipped too.)

Ah, thanks for pointing that out!
