Dev-testing code changes to chia?

[cross]

Hey. I wanted to make some changes to address a bug, and know how to create a PR via GitHub. But, I can't find any docs for running chia out of a local source tree. The install docs cover installing it with pip in a venv, but I'm not an expert on python venv, and am not sure how to actually run it from inside of a modified source tree.

Is this possible? Are there instructions somewhere? Thanks.

@emlowe commented in bug #8565 :

If your harvester is on Linux/MacOS - it's pretty easy. Just run pip install -e ".[dev]", then edit your python, save the file, and run it inside the venv. So

• sh install.sh
• pip install -e ".[dev]" - the install.sh may already do this, but it doesn't hurt
• source ./activate
• Edit and save your changes
• chia start harvester

You only need to do the first 3 steps once, then you can edit python and make whatever changes you want as many times as needed.

This can also be done on Windows, but it's a little more work to set. We have new powershell scripts to help setup though you can look at install.ps1.
