Setting up vscode for debugging poetry

[jpmorris]

I'm running into all sorts of problems with my setup running certain commands (windows, cygwin, wsl) with poetry (in particular "poetry add source...")--certificate errors, 'is a directory' errors and one other I cant recall. If this was a simple import in python code I'd be able to just step into module code and get an idea of what's going on. And wouldn't mind passing on any issues I find to devs. However, I don't know how to do this type of debugging with a cli binary python command. (I'd prefer to do this in vscode, but if you can tell me in pycharm I can probaly translate the instructions.)

I figure python -m poetry might be part of it. I see vscode supports module run configuration but I don't see how I get an entrypoint into it once I run. I don't see any mention of deveopment setup in the poetry documentation. I suppose I may be ablet o hack some main() entrypoint ina script which sends arguments to poetry module (not cli binary) and enter that way, but not quite sure where to enter or if that's even the best way. How can I debug poetry when I'm using it as a cli binary so I can set breakpoints (and even better, post-mortem debugging just before/after the cli/stderr warnings/errors are displayed. Is there any example of how to get started with a poetry debugging setup?

Found out how:
In VSCode use the following launch.conf:

 {
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python: Module",
            "type": "python",
            "request": "launch",
            "module": "poetry",
            "justMyCode": false,
            "cwd": "C:\\Users\\<username>\\python3.8.10\\Lib\\site-packages",
            "args": [ <arguments for the command you wnat to debug>
            ],
        },
    ]
}

Then run main.py as the entry point. It should run your command and you can debug the errors

As far as my issues (for anyone else):

• if using requests library export REQUESTS_CA_BUNDLE if you're behind a corporate firewall to add your companies certificate. If cygwin /etc/pki/ca-trust/source/anchors/<your companies cert .crt file>
• Don't mess up the syntax! It's not "poetry add source", it's not "poetry add --source" (to add the source) it's "poetry source add" otherwise you'll get errors of 'permisison denied' when you try and add a no-name package when you thought you were adding the source. (ill try and submit a pr)
• also --vvv to see the stacktrace was very helpful
