[Bug] Limiting status output falsly claims "Task list is empty"

[Cook-I-T]

Describe the bug

I tried to check in a Bash script if there's still a task running in a certain group with the bash command pueue status -g group columns=Status status=running first 1 | grep 'Running' | wc -l
I expect that when a group still has any running task it outputs one row of "Running" which gets converted to a 1, with nothing running outputting 0.

Steps to reproduce

• Add 2 groups
• Add multiple Tasks to both of them
• Now query the status of the groups with pueue status -g {GROUPNAME} columns=Status status=running first 1
• One group will say the expected "Status" Column with one row saying "Running" while the other falsly outputs "Task list is empty."

cookit@cook-pc:~$ pueue group add g1
Group "g1" is being created
cookit@cook-pc:~$ pueue group add g2
Group "g2" is being created
cookit@cook-pc:~$ pueue add -g g1 sleep 60
New task added (id 0).
cookit@cook-pc:~$ pueue add -g g1 sleep 60
New task added (id 1).
cookit@cook-pc:~$ pueue add -g g1 sleep 60
New task added (id 2).
cookit@cook-pc:~$ pueue add -g g2 sleep 60
New task added (id 3).
cookit@cook-pc:~$ pueue add -g g2 sleep 60
New task added (id 4).
cookit@cook-pc:~$ pueue add -g g2 sleep 60
New task added (id 5).

True, that seems to be a bug.

Feel free to investigate and create a PR :) I'm not sure when I have the time to look at this.

[Cook-I-T]

I looked at the code in pueue/src/client/query/ but since I never worked with Rust (and never heard of pest before) I sadly can't help with fixing that bug :(
I did figure out that increasing the number somehow makes lines appear again (so for example first 2 shows 1 line of "Running"), but it's not consistent.

For my usecase however I did realise that columns=Status status=running is already limiting the lines of output to the "parallel" count of the group, which makes the magical performance & efficiency I hoped to gain from first 1 kinda irrelevant. I just added a quick head -n 1 after grep and I'm back to the "0 or 1" output I want :)

Thanks for developing this amazing tool, if there's a way to support this project outside of PRs I'd gladly help :)
Vielen Dank aus Österreich ^_^

submitted a fix here #512

Thanks for fixing my bug report!
I installed rust, compiled your fork and from what I can see, it fixes the problem :)
Now it just requires @Nukesor's approval and another bug is squashed ^_^

[Cook-I-T]

I was just compiling the " fix-group-filtering" branch when it got merged, (again) from what I see it fixes the issue, looking at the changes I again have no idea how it works but it does :)
I'm not sure if I should close this issue or not so I'll just leave it...

Thanks again for all the good work! ^_^
