Is there a way to attach a debugger to the pants process? I’m trying to debug a plugin and I’d like to set a breakpoint in my plugin code.

I believe yes thanks to @bitter-ability-32190 🙂 https://github.com/pantsbuild/pants/pull/15951

Ooo! Is that released, or do I need to set the PANTS_SHA?

wait to clarify, do you want to debug Pants itself? Or something like

run

? Because in sibling PRs, Josh added support to that too

Right now you can't easily debug a pants plugin, but it's maybe 1 PR away

I’m writing a plugin as a first step towards parsing PEP621, and I’m getting an error I don’t understand. I wanted to drop a breakpoint at the spot where the error is raising in my code

Well let me clarify, debugging a plugin in your own repo isn't supported yet. If you're doing it in the pants repo you can run pants with PANTS_DEBUG=1
