hey folks, is it possible to get into a debugger when running

./pants

command with in-repo plugin code being executed? If I add

import pdb; pdb.set_trace()

inside my plugin code, I get

Exception: stdin is currently Exclusive owned.

in the terminal

At some point I was gonna explore

PANTS_DEBUG

(which is in the pants repo) but for end-users. It might be possible to cobble together. You use VS Code?

can use vscode if that will help 🙂

for now, I just run the

./pants

from a terminal; it's a trivial piece of Python code in the plugin

So there's twoish pieces to solve. I can take a stab at it in about 15-ish minutes

I use:

Copy code

[cli.alias]
plugin-dev = "--no-local-cache --no-dynamic-ui --print-stacktrace --no-concurrent"

Alrighty, taking a look now. Let's see how quick this will go 😛

OK I'm so perplexed with bash and spaces

Copy code

DEBUG_ARGS='-c "__import__(\"sys\").path.pop(0);__import__(\"debugpy.server.cli\").main()" --listen 127.0.0.1:5678 --wait-for-client'
exec python ${DEBUG_ARGS}

and nothing happens

OK @fresh-cat-90827 you should be able to upgrade your pants shim and use

PANTS_DEBUG=1
