ruffruleannotator is a small tool designed to enhance the readability of Ruff configuration files by annotating all rule IDs with their corresponding titles. This allows users to easily understand the purpose of each ignored/selected rule within their codebase. Additionally, ruffruleannotator can sort the rule IDs within the relevant sections of the TOML file, ensuring a well-organized and readable configuration.
Consider the following pyproject.toml
:
[project]
name = "packagename"
[tool.ruff.lint]
select = ["D100", "D103", "ERA001", "PLR2004", "F"]
ignore = ["E501", "B"]
[tool.ruff.format]
quote-style = "single"
Executing ruffruleannotator
yield a reformatted config with annotated rule IDs:
[project]
name = "packagename"
[tool.ruff.lint]
select = [
"D100", # undocumented-public-module (pydocstyle)
"D103", # undocumented-public-function (pydocstyle)
"ERA001", # commented-out-code (eradicate)
"F", # Pyflakes
"PLR2004", # magic-value-comparison (Pylint (Refactor))
]
ignore = [
"B", # flake8-bugbear
"E501", # line-too-long (pycodestyle errors)
]
[tool.ruff.format]
quote-style = "single"
pip install ruffruleannotator
The tool automatically recognizes ruff configs inside pyproject.toml
and ruff.toml
. The entries select
, ignore
, fixable
and unfixable
inside the Ruff lint section of the config are supported for reformatting. All other parts of the file stay unchanged.
Execute the tool inside project root directory:
ruffruleannotator
By default a backup of the config file is stored under ~/.ruffruleannotator/backup
. Only the latest version of each project directory is stored. The creation of a config backup can be ignored:
ruffruleannotator --no-backup
By default ruffruleannotator
sorts the rule IDs within the sections alphabetically. The order of entries can be preserved:
ruffruleannotator --no-sort
By default ruffruleannotator
shows changes and waits for user confirmation before cactually changing the config:

By default all expected changes are shown before applied and the user must confirm. The manual confirmation can be skipped:
ruffruleannotator --yes
Consider the following config file:
[tool.ruff.lint]
select = ["F404",
"F403",
# Comment lines break the sorting. Rule IDs are sorted
# seperately above and below the comment line.
"F406", # already commented lines are not annotated
"F402",
# Lines with multiple rule ids are split
"E112", "E111",
"E113"]
After reformatting:
[tool.ruff.lint]
select = [
"F403", # undefined-local-with-import-star (Pyflakes)
"F404", # late-future-import (Pyflakes)
# Comment lines break the sorting. Rule IDs are sorted
# seperately above and below the comment line.

"E112", # no-indented-block (pycodestyle errors)
