"You have running jobs" warning

"You have running jobs" warning

[Hrvoje Niksic]

When I set NO_HUP, I would like the "you have running jobs" warning to
disappear when leaving zsh, since the option should make it look like
other shells in that respect (e.g. bash prints no warnings about
background running jobs).

Thus, if nohup is unset, the warning should be printed and the shell
should require pressing C-d twice to exit, HUP-ing the job before
exiting.

However, if nohup is set, there should be no warning about running
background jobs, and only one C-d should be sufficient to exit. This
little patch does this. Could you please include it to the
distribution, since the modified behaviour strikes me as much more
logical.

If you unset the MONITOR option, you won't get the warning.

I am not sure I follow you.
          MONITOR (-m)
               Allow job control.  Set by default in  interactive
               shells.
 
What does this have to do with what I have written?

If you disable job control, you will not get the warning when
terminating the shell.

Well, yes of course. If I kill -9 $$, I will also get no warning, but it is
definitely not what I had in mind.

You can alias exit to 'unsetopt monitor ; exit' or you can write an exit
function which checks if there are suspended jobs and exits unconditionally
if no suspended jobs found and gives a warning otherwise.  This way you can
write an exit which does exactly what you want.  The main point that this
can be done uning the existing shell tools so we should not complicate the
code with this.  Also many people (including myself) perfer the present
behaviour.  I always use setopt nohup but I'd still like to get warnings.

Yup, it does seem like a matter of taste, and since you're the
coordinator... ;)

You can use 

% something &|
% exit

and zsh will not complain.

Well, it seems to be a matter of taste. When I background a job, it is most
often quite normal to log out.

<patch omitted>

I don't see this as logical at all.  I have "nohup" set but always
appreciate the warning that zsh gives when I'm about to abandon a
job.

Perhaps another option to control this is what you require.
