Alias and zstyle contexts

Alias and zstyle contexts

[Silas Silva]

Hi there!

Fortunatelly, aliases use the same context of original commands, which
which make things much easier.  But a little problem just came up:

mutt's -f option looks for mailboxes using the mail-directory style.  I
have a "muttw" alias that I'd like to load mailboxes from another
directory, but the context is the same.

I could solve this having a function called muttw, copying original
_mutt completion to _muttw and changing just one line, but this looks
ugly.  Is there an simpler way?

Thank you very much!

Just making a function and saying compdef muttw=mutt should be enough.

Hi!

It works fine, thank you!  But, unfortunately zsh's _mutt file checks
if $curcontext is mutt or some other alternatives.  Since I now have
muttw context, it doesn't work well.  Is it possible to trick _mutt
without having to change its code?

Thank you very much.

I don't have mutt so I can't try this, and if it doesn't work, maybe
someone else has a suggestion.
compdef -e 'curcontext=:complete:mutt:w:; _mutt' muttw
and then set the mail-directory style for that tag instead. Maybe?
There may be some much more elegant way to do this (if it at all
works).

Hi Mikael and guys,

Thank for the tip.  It would work fine, if there wasn't a problem:
_mailboxes has a _mailbox_cache variable that would prevent the code to
evaluate again even in another context.  The workaround I came up with
is:

    compdef -e 'curcontext=:complete:mutt:w:; _mutt; unset _mailbox_cache' muttw

This is not beautiful but it works.

Is a patch to make _mailboxes work with different contexts and yet be
efficient (working with different cache for different context)
desirable?

Thank you very much!

% compdef muttw=mutt

should do the trick.
