zsh Newbie wants to complete mutt email addresses or aliases

zsh Newbie wants to complete mutt email addresses or aliases

[Kingsley G. Morse Jr.]

Hi everyone!

I'm new here. Linux Magazine's recent article on migrating from bash
persuaded me to try zsh. I'm glad to see it has a friendly license and
naturally I'm looking forward to fully utilizing zsh's completions.

The main reason that I'm writing is to ask for advice on configuring zsh
to complete mutt's destination email addresses.

For example, can zsh be configured to complete the following

        $ mutt -s "A Silly Subject" Joe_Do<tab>

so that "Joe_Do" is expanded to the correct email address
Joe_Doe@somewhere.com"?

I'd also be OK with expanding "Joe_Do" to the correct mutt address alias
"Joe_Doe".

Thanks,
Kingsley

Currently, mutt completion doesn't know about aliases, though this
should be trivial to change.

Right now it tries to complete destination addresses based on users and
hosts it knows about, which probably isn't too convenient for what you
want to achieve.

Do you keep your aliases in .muttrc or elsewhere?

Depends.  Have you set up query_command and are you using that?

Perhaps a better route, for someone who cares [1], might be to look at
wrapping zsh completion around the same query command.  Then, if mutt
has been correctly installed at a site, so that the site addressbook is
queries (whether LDAP, NIS or whatever) then zsh would have access to
the same information.

A search for "External Address Queries" in the mutt manual should turn
up the information and specification for the format of the returned
data.

zstyle -e ':completion::complete:mutt:*:' users \
	'reply=($(perl -ne '\''print "$1\n"
		  if /^\s+alias\s+(\S+)\s+.*/;'\'' ~/.muttrc 2>/dev/null)
		otheraddress@notinmuttrc.com
		anotheraddress@whoknowswhere.com
		etcetc@andsoforth.net)'

You can probably figure out how to extend this to emit the addresses from
the muttrc alias lines instead of just the alias keywords.

Bart,

Thanks for the code. 

I'm OK with just completing aliases and appreciate your pragmatic
approach.

However, probably due to my inexperience, I was unable to get your code
to work after 

1.) deleting the hard coded email addresses, leaving

        zstyle -e ':completion::complete:mutt:*:' users \
        'reply=($(perl -ne '\''print "$1\n"
                  if /^\s+alias\s+(\S+)\s+.*/;'\'' ~/.muttrc 2>/dev/null))'

2.) putting it in .zshrc and restarting zsh, and failing that,

3.) entering it at zsh's prompt.

When I press <tab> after typing the start of an alias, ie:

        $ mutt -s "A silly subject" Joe_Do<tab>

zsh returns the same error message as before:

        No matches for: `recipient', `login name', `user', or `corrections'

Since I'm so new to zsh, perhaps you can easily suggest what I might try
doing differently.

Thanks,
Kingsley

First thing to try is, run the perl all by itself:

perl -ne 'print "$1\n" if /^\s+alias\s+(\S+)\s+.*/;' ~/.muttrc

Does this produce an error message?  Does it produce the right output?

If that appears to work, you dan debug the completion itself by using

$ mutt -s "A silly subject" Joe_Do<C-x ?>

That is, type control-x question-mark instead of tab.  This will dump a
trace of the completion code to a temp file, where you can look at it.
Search it for "perl" to see whether and how the style above is being used.

Take out the initial \s+ in your perl regex, that should clear it up
(alias lines usually don't have preceeding whitespace.)

D'oh!  That should have been \s* ...

Thanks! 

It worked!

Two minor observations:

1.) Although the zstyle/perl code worked as we expected when I entered it
at zsh's prompt, when I added it to .zshrc and subsequently started zsh,
it reported 

        "no such file or directory"

until I appended the first two (out of three) lines of the code. The
resulting .zshrc code that works for me is

        zstyle -e ':completion::complete:mutt:*:' users 'reply=($(perl -ne '\''print "$1\n"
                  if /^\s*alias\s+(\S+)\s+.*/;'\'' ~/.muttrc 2> /dev/null ))'

2.) Now when I use <tab> to complete mutt's email aliases, the completed
aliases sometimes end with an "@", which conveniently goes away when I
press <enter> to run mutt.


All in all... all's well that ends well.

Marius: I like your lost cable signature.

All: As a small token of my appreciation for your time and attention,
here's a tame joke:
