Exiting out of zellij run does not release its $ZELLIJ_PANE_ID

[flinesse]

I was looking into ways to IDEify my editor (hx) with Zellij #2835, #2795 and came across a behavior I believe is errant:

When you exit from zellij run through its intended means (via <Ctrl-c>/--close-on-exit), the $ZELLIJ_PANE_ID env variable does not get decremented as one would see from closing panes.

This behavior is also inconsistent with the documentation's description of zellij run:

-c, --close-on-exit ---- Close the pane immediately when its command exits

..<Ctrl-c> to close the pane.

I have not yet done enough code sleuthing but I believe the terminal_id's from which $ZELLIJ_PANE_ID is derived from is not being treated the same way when the run subshell is --close-on-exited vs. close-paneed.


ver: zellij 0.39.1

Great find! Thank you 😄

Indeed a good find, thank you! While I will not mind a fix here - just know that this is what I'd consider undefined behavior. We can't promise to stay consistent on this one - rather we can only promise to give unique PANE_IDs to each pane.
