jobs numbers in prompt

jobs numbers in prompt

Hello, 

In my current prompt I have a list of background jobs (if there are
any). This works like this:
    myjobs=${(pj:\,:)${(k)jobstates}}
 
And gives a list like: 1,2

Now my question, is there any possibility to include the current job
(+ sign) and previous job (- sign) in this output? Like this: 1-,2+

Is this possible? If been fighting with $jobstates all week, but I've
been unable to extract multiple fields from this array.

thanks in advance,

Does this work?
myjobs=();for a (${(k)jobstates})
{j=$jobstates[$a];myjobs+=($a"${${(@s,:,)j}[2]}")};myjobs=${(j:,:)myjobs}

fyi: it needed one small tweak, if you have more than 2 bg jobs:

    myjobs=()
    for a (${(k)jobstates})
    {j=$jobstates[$a];i="${${(@s,:,)j}[2]}"
    myjobs+=(a${i//[^+-]/})}
#              ^^^^^^^^^^^^^^
#        filter out anything but + or -
    myjobs=${(j:,:)myjobs}
