completion with a PATH assignment

completion with a PATH assignment

[Helmut Jarausch]

Hi,

I often use

export PATH=/usr/local/gcc-<TAB>

but unfortunately tab-expansion doesn't work here.
Is there a workaround?
I am using 4.3.0-dev-1

Many thanks for a hint,

It should do.  I can't think of a good reason why it wouldn't.

I have a similar problem:

svn commit bla-<TAB> (and there is really a file which it can be expanded to)

TAB expansion did not worked in this case too. I'm using zsh 4.2.5.

That's actually a very different problem.  I think the _subversion
completer has been somewhat rewritten since then.  It might be worth
patching the latest version onto the 4.2 branch, if anyone is
sufficiently au fait with the status (I'm not a subversion user).

So this means that even thus just the completion of a filename is needed,
this must especially coded for each supported command like svn? Shouldn't
there be some kind of fallback? I mean if zsh is not able to expand it,
maybe it should just try filenames in the current directory instead?

Yes, essentially:  the context has to invoke _files, which doesn't
involve much coding but must be done explicitly.

In principle it should be able to expand it; it's a bug that it can't.

It's easy to get plain old file completion bound to a separate key.
Given that the contextual completion is already complicated, this tends
to make more sense than yet more guessing.  For example, if you bind
_bash_completions to Esc / you get file name completion.  Or you can
create a widget:

  zstyle ':completion:plain-old-file-completion:*' completer _files
  zle -C plain-old-file-completion complete-word _generic
  bindkey '^xf' plain-old-file-completion

Or if you really always want file completion as a fallback, you can add
_files to the default completer list.  For example,

  zstyle ':completion:*' completer _oldlist _expand _complete _ignored \
  _approximate _files
