list all jobs before prompt

list all jobs before prompt

[Michael Wardle]

Hi

I would like zsh to list /all/ jobs when I suspend one.

A reasonable method is to add "jobs" to my precmd function, but this
will cause zsh to print a status message for the suspended job and list
the same job again in the output of "jobs".  I don't see the need for
the suspended job to be listed twice.  It also looks a bit silly if the
command I type at the prompt is "jobs". :-)

I could also do a lot of manual filtering in precmd, but I would have to
make some assumptions and it still wouldn't produce the desired,
consistent output format unless I could also prevent the default message
on suspension.

Is there a better way to accomplish this?

The closest behavior to what I desire is tcsh's listjobs option.

I think the closest you can get without a modification of the source code
is this:

precmd () {
  local x=$?	# This must be the first line of precmd!
  # ... do whatever precmd stuff you already do, then ...
  # This requires zmodload zsh/parameter plus extendedglob:
  (( x == 20 )) && jobs %${(k)^jobstates[(R)^*:+:*]}
}

Not a lot, is it?

Oh, well; you can't always get what you want.

Perhaps the two good solutions are:

1. make the suspend message match the format of the jobs command

Sending a STOP signal (usually via Control-Z) to a process would print
(for example):

[1]  + suspended  vim

instead of:

zsh: suspended  vim

Bash does this and I think it would be quite useful.


2. add support for an option similar to listjobs in tcsh


Is there any interest in either of these suggestions?

I agree. I didn't even know I was missing that bash feature :-) In
bash I've never used the 'jobs' command, in zsh I do...because I don't
know the job numbers.

What is needed for this? I expect any change for this to be minor.

I don't know what that is,
