Re: fg jobs info

[Atom Smasher <atom@smasher.org>]

maybe in the process of working out the bugs, there can be some added 
functionality to add a variable that automagically returns the text of the 
fg'd job.

in the meantime, i'm keeping it (relatively) simple and assuming that i've 
only got one job at a time suspended (for me, that's a reasonable 
assumption; YMMV). my preexec runs a function (to display the command name 
in tabs, title bars, icons, etc), and part of the function is simply:

     if [ 'fg' = "${${(z)@}[1]}" ]
     then
       cmnd_name="${(vV)jobtexts}"
     fi

as far as i can tell, the worst case failure is that it will display the 
commands of more than one job. considering the lengths i'd have to go 
through to fix that, and the chances of introducing more bugs, and how 
often i have multiple jobs suspended within a shell (not very often) i 
think this is good enough, for now.

thanks...
