compctl question

compctl question

[Philip J. Hollenback]

I'm using zsh 3.1.5, and I'm trying to develop a completion for mutt.
Here's what I currently have:


mutt: if -f, -i, -a, or -H is given, complete files,
# and if -f+ (or -f=, or -f +) is given, complete folders in
# ~/mail.  Also complete options after -. 
# Note that '-f =' can't be completed because '=' is grabbed by the
# shell.  It needs to be protected with a '\', but I don't know how to
# make the completion do that.
# Don't complete users because I never mail anyone on my own system.
compctl -x 's[+] c[-1,-f],s[-f+],s[-f=]' -W ~/mail -f \
  - 's[-[fiaH]],C[-1,-[fiaH]]' -f \
  - 's[-]' -k '(a b c e f F H i m n p R s v x y z Z h)' \
  -- mutt


I like to open mailboxes in my mail directory thusly:

# mutt -f =mailbox

That doesn't work, Apparently because the shell does something with
words that start with '='.  I can't complete on =mailbox either,
for the same reason.

Now, this does work:

# mutt -f=mailbox

as does this:

# mutt -f \=mailbox

However, I am accustomed to typing the command as

# mutt -f =mailbox

So here are my questions:

1. How do you get around the fact that the shell grabs the '='?  Can
you turn that off for this one command?

2. Is there a way to write a completion that rewrites the what is
already on the command line?  For instance, if I typed in this:

# mutt -f =mailb<tab>

could the shell expand it to

# mutt -f \=mailbox

or

# mutt -f=mailbox

by changing what had already been typed?

I have perused the manual carefully, and have been unable to develop an
answer.

Thanks,
Phil.

	the EQUALS option, when set, tells the shell to interpret
# =foo
	as
# $(which foo)
	which is probably what is causing your problems.  if you don't
make use of that functionality, you can just unsetopt EQUALS and it
should work the way you would expect.

Just use `-x "s[=]"' or `-x "S[=]"':

  comcptl -x 's[=]' -W ~/mail -f -- bar

This is a bit tricky:

  foo() { reply=( ~/mail/${1[2,-1]}*${2}(N:t) ); reply=( \\\=$^reply ); }
  compctl -x 'S[=],S[\\=]' -UQK foo -- bar

But this has the side-effect of turning on menucompletion if automenu
is set.

Compctl question

[Erwin J. van Eijk]

Hi

This is in the manpage somewhere, but I can't quite get a fix on how
to do it.

I have a command named really, which has the following cmd line:

really [-u username] [-s shell] command

And I want to compose a compctl for it, but I can't quite do it.

Thanx
EJ

Something like:

getshells() {
	reply=($(sed '/#.*/d' /etc/shells))
}
compctl -l '' -x 'c[-1,-u]' -u -x 'c[-1,-s]' -K getshells -- really

should work (it appears to for me at least...)
