Formatter for pyproject.toml files

This package enforces consistent formatting of pyproject.toml files, reducing merge request conflicts and saving time otherwise spent on manual formatting. It also contributes to a cleaner git history and more readable code; enhancing overall project organisation and maintainability. Experience a streamlined workflow, reduced errors, and improved code readability with pyprojectsort.

• Alphanumerically sorts pyproject.toml by:
  • section
  • section key
  • list value
• Reformats pyproject.toml to a standardised style
  • line per list value
  • double quotations
  • trailing commas
  • indentation
  • end of file newline

pyprojectsort is available via PyPI:

pip install pyprojectsort

To use as an automated git hook, add this to your .pre-commit-config.yaml:

- repo: https://github.com/kieran-ryan/pyprojectsort
  rev: v0.4.0
  hooks:
      - id: pyprojectsort

With the following pyproject.toml:

[tool.ruff]
ignore = ["G004",
"T201",
    "ANN"
]

[project]
name = 'pyprojectsort'
authors = [
    { name = "Kieran Ryan" },
    "Author Name <[email protected]>",
    {name="Author Name"}
]

[tool.radon]
show_mi = true
exclude = "tests/*,venv/*"
total_average = true
show_complexity = true

[build-system]
build-backend = "flit.buildapi"
requires = ["flit"]

Run the package from within its directory:

pyprojectsort

The configuration will be reformatted as follows:

[build-system]
build-backend = "flit.buildapi"
requires = [
    "flit",
]

[project]
authors = [
    "Author Name <[email protected]>",
    { name = "Author Name" },
    { name = "Kieran Ryan" },
]
name = "pyprojectsort"

[tool.radon]
exclude = "tests/*,venv/*"
show_complexity = true
show_mi = true
total_average = true

[tool.ruff]
ignore = [
    "ANN",
    "G004",
    "T201",
]

The pyproject file path can alternatively be specified:

pyprojectsort ../pyproject.toml

The --check option can be used to determine whether your file would be reformatted.

pyprojectsort --check

If the file needs reformatting, the program exits with an error code. This is useful for pipeline integration as it prevents writing back changes so that a clean repository is maintained for subsequent jobs.

The --diff option provides similar functionality but also displays any changes that would be made.

pyprojectsort --diff

The diff of an alphabetically reordered array will appear as follows:

@@ -6,8 +6,8 @@
[project]
authors = [
+ { name = "Author Name" },
  { name = "Kieran Ryan" },
- { name = "Author Name" },
]
