Problem with autocompletion

Problem with autocompletion

[Andrea Morandini]

Hi everybody,
			I have a noob question.

Zsh is much better than my previously bash, but I miss a very basic function.

When I try to autocomplete the file path, using TAB, i receive the following error:

cap staging deploy:upload FILES=my_app_dir/the_file_i_would_to_autocomp            
_cap:compadd:7: can only be called from completion function


So the first part of the string "cap staging deploy:upload FILES=" is typed by me, but when I try to autocomplete the last  part it fails.

Any suggestion on how to patch/debug ?

"_cap" isn't a standard completion function supplied with the shell, so it
looks to me like something funny is going on in there.  Find out what
that's doing and how it's been configured---does it have "#compdef cap" at
the start and does "print $_comps[cap]" output "_cap"?  The file
_cap will be somewhere in the list of directories you see with
"print -l $fpath" ("print ${^fpath}/_cap(N)" should tell you where
it is).

I presume you have run "compinit" in .zshrc to load the completion
system?  _cap is clearly assuming it's present (but for some reason finding
it isn't).

This seems to indicate that TAB has been bound to a function that was
installed as a normal widget rather than as a completion widget (via
"zle -C"), although I would have expected things to fail a lot sooner
in that event.  What output do you get from

bindkey ^I

(that is, bindkey with only one argument, which is caret capital eye)?

What do you get if, instead of TAB, you type control-X question-mark
after the equal sign?
