pyproject.toml configuration wrapper for pyupgrade

Via pip

pip install pyproject-pyupgrade

Via poetry

poetry add --group dev pyproject-pyupgrade

Via pipx

pipx install -f pyproject-pyupgrade

Make sure you have a desired version of pyupgrade installed in your python environment.

Add the following section in your pyproject.toml:

[tool.pyupgrade]
# for example, if you're using python 3.10
py310-plus = true

And then just execute it via CLI

pyproject-pyupgrade [filename [filenames...]]

or shorter version

ppyupgrade [filename [filenames...]]

So, basically you specify flags that you want to add to pyupgrade CLI arguments specifying them without leading two dashes (--). This is the way how you can supply any option that your version of pyupgrade receives

There is also one additional parameter provided exclusively by pyproject-pyupgrade wrapper:

[tool.pyupgrade]
pyproject-pyupgrade-debug = true

Or directly via CLI

ppyupgrade --pyproject-pyupgrade-debug ...

This option is going to output debug information about pyproject-pyupgrade. Info about parsed configuration from pyproject.toml (if there is one) and all the flags

See pre-commit for instructions.

• Add tests and tox config to run them for all supported python versions
• Add option to specify custom pyupgrade command. It allows in case if you want to chain pyupgrade wrappers (for instance, with pyupgrade-directories)
• Add better parser for TOML. Right now the parser is ultra primitive and might lead to errors if used improperly
• If python version >= 3.11 use tomllib for pyproject.toml parsing
• Support adding custom options or key-value arguments to pyupgrade CLI
• Support storing configuration in pyupgrade.ini
• Support storing configuration in tox.ini
• Support storing configuration in setup.cfg
