Do you deal with lots of virtual python environments? rpy is for you!
Before rpy:
~/dev/prj$ env PYTHONPATH=src/py path/to/my/interpreter src/py/my/script.py --my --args here
After:
~/dev/prj$ rpy src/py/my/script.py --my --args here
rpy looks for a pyproject.toml file relating to the script, and then looks for a tool.py section of the form:
[tool.rpy]
# All paths are relative to the project root (which is wherever we found the pyproject.toml
interpreter = 'out/env/bin/python' # path relative to the project root
source_root = 'src/py' # Optional PYTHONPATH to set up (defaults to project root)
pre_run = 'make --quiet deps' # Optional command to run in the project root first
