that's what i was thinking. Still it helps a beginning
compstyle-user. perhaps something like that for the _complete_ functions?

Hmm, a name that really does not explain anything, does it?
So in order to use it one has to know it first :)

On the other hand I am happy that I can use this function, thank
you!

Yes. The one who wrote it probably should have documented it
somewhere.

I /think/ it wasn't me this time.

It stands for "use long options", because it used to be a wrapper for the
now-defunct _long_options completer (which was completely subsumed by
_arguments some while back).

} 
} Yes.

However, note that all it does is call _arguments, which is what 98% of
the completers for other commands also do.  So most commands for which
there is a special completion already have the ability to complete based
on --help output:  It's triggered by completing after `--'.  Try, for
example

	% tar --<TAB>

and watch the fun.

Which reminds me, Sven:  There's still the bug where setting the `menu'
style to `select=N' for some number N is not working at all.  Menu
selection never starts for me.

This is very interesting.

The earliest mention of _use_lo in the zsh-workers archive is PWS saying
"What happened to _use_lo?  I don't remember removing it." just before he
made the 3.1.6-test-1 release.  That's the first time it shows up in my
home CVS repository, too.  The ChangeLog-Release file doesn't mention it
at all until Sven started patching it (and the entire contents except for
the comment at the top have long been Sven's doing, even if he didn't
create the file originally).

Of course, the ChangeLog also doesn't make any mention of when _arguments
acquired the internals of _long_options.

squeaker% tar --_main_complete:142: permission denied:
<then I press ENTER again>
tar: You must specify one of the `-Acdtrux' options
Try `tar --help' for more information.

Let me know if there is more I can help to debug this.  Line 142 of
_main_complete is:

    elif "$tmp"; then

The standard thing nowadays is to use the _complete_debug binding, which
should be ctrl-x question-mark.  You type <C-x?> instead of <TAB> at any
lace where the new completion system is giving you trouble, and it'll
`setopt xtrace` (temporarily) and dump the output into a temp file.

An entry is made into your command history to run an editor or pager on
the temp file (so you can use ctrl-p to find it).  Most of the time it
also manages to tell you what it did and the name of the temp file, but
that doesn't always work because other completion output may cover it up.  

} Line 142 of _main_complete is:
} 
}     elif "$tmp"; then

(That's line 152 in the latest CVS snapshot.)

That's supposed to be executing a completer, which should be a shell
function.  If that's really where the error is occuring (I ought to trust
zsh's line numbering more than I do) then you probably have a bad entry
in your "completer" zstyle.

Huh? It works for me when I do something that would start
menu-completion (automenu or...). And if there are enough matches, of
course.

And without explicitly loading complist.

Sorry, I'm confused.

What I was expecting, for some reason, was that menu selection would start
immediately if there were more than N matches, not wait for the second TAB
that triggers automenu.  I.e., I want automenu (two TAB) behavior if there
are fewer than N matches, and menu-select (one TAB) behavior for N or more.

I don't know how I got the idea in my head that select=N by itself works
that way.  Is there a configuration that does work that way?

Sounds interesting. Actually, it looks like more general form of menu
style ... currently we can set it so, that menu selection starts when
matches do not fit on screen; more general style would allow exactly
what you want.

I am perfectly sure it is a matter of one line in the _main_complete; I
just looked where select=long is looked up - should be the right place.
