completion for darcs

[Andrei A. Voropaev]

Hello!

System of completion in zsh is very powerful and very addictive :) The
more painful it is, when it fails for some reason. I was very impressed
with completions for gnu arch commands. And now I'm trying out darcs,
but seems like here completion is not so good. I'd rather say it hinders
me instead of helping. The very first thing I try to do is to add a
file. So I do 'darcs add f<Tab>'. All I get in response is "Completing
`arg for darcs command'". No file name. So I have use copy/paste to get
file names into command line.

What could be the problem here? Any solutions?

Oops. Sorry for noise. I've found the answer already on the darcs wiki.
I just need to type ./f<Tab> to get it working.

I also have, sometimes, this kind of problem. Would it be possible to
add a ZLE widget like "file-complete" (that would be bound, for instance,
to Ctrl-Tab) which forces the completion to happen in a "basic" way, rather
than with the new functions-customized system? It is very annoying to have
to type a full filename...

Or may be such a widget already exists?

I don't know whether one exists or not, but you probably won't be able
to bind to Ctrl-Tab.  On all the terminals I have lying around, it
produces a plain tab for zsh to see.

With X, It is possible by adding some modifications in .Xdefaults:

*VT100.Translations:    #override\
     Shift ~Ctrl ~Meta<Key> BackSpace: string("\033[40;2~") \n

With the Linux console, you have to modify files used by loadkey.

I configured my system to use ctrl+arrows to move cursor from word
to word, or ctrl+backspace to delete a full word... it is very handy
and I don't have to remember all that prehistoric shortcuts from
vi/emacs ;-)

Shouldn't it be possible to just tell zsh that when there are no
completions for an argument, it should fall back to completing files?

There are indeed many commands where I find that "smart" completion is
a nuisance. This wouldn't solve the problem for all of them, but it
would go a long way. I really don't like completion definitions that,
for instance, only let me complete files matching *.mp3. Maybe a
separate key binding for 'complete files', as is being discussed, is
still the correct solution, I don't know, but it would be nice if some
standard key binding were available in the default configuration.

Sure.  And it is.  I'm surprised no one has mentioned this yet.  Just
put "_files" directly into your "completer" zstyle somewhere.  E.g.:

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

Where you place it will determine the precedence taken by file completion
with respect to "repairs" (like partial and approximate matching) done on
the completions suggested by the more context-specific completer selected
by _complete.

Yahoo! :) Works perfectly :)

I suppose _bash_complete-word and _bash_list-choices may be about what
you're searching for. Look them up in the manual to see how they're
used, for they have a somewhat special behaviour with respect to the
binding.

You can actually use the flexibility of the style system and the
_generic widget to do this.

zle -C complete-file complete-word _generic
zstyle ':completion:complete-file::::' completer _files
bindkey '^xF' complete-file

This defines a new widget called "complete-word".  The completer style
in the appropriate context is set to _files, so when invoked it simply
completes file names.  Then it's bound to \C-xF.

There are infinite variations on this.  If you have "From Bash to Zsh",
see pages 405 to 407.

I meant "complete-file", of course.
