reStructuredText linter

Project description

Build Status

reStructuredText linter

This was created out of frustration with PyPI; it sucks finding out your reST is invalid after uploading it. It is being developed in junction with a Sublime Text linter.

Getting Started

Install the module with: pip install restructuredtext_lint

import restructuredtext_lint
errors = restructuredtext_lint.lint("""
Hello World
=======
""")

# `errors` will be list of system messages
# [<system_message: <paragraph...><literal_block...>>]
errors[0].message  # Title underline too short.

CLI Utility

For your convenience, we present a CLI utility rst-lint (also available as restructuredtext-lint).

$ rst-lint --help
usage: rst-lint [-h] [--format FORMAT] [--encoding ENCODING] filepath

Lint a reStructuredText file

positional arguments:
  filepath         File to lint

optional arguments:
  -h, --help            show this help message and exit
  --format FORMAT       Format of output (e.g. text, json)
  --encoding ENCODING   Encoding of the source file (e.g. utf-8)

$ rst-lint README.rst
WARNING README.rst:2 Title underline too short.

Documentation

restructuredtext-lint exposes a lint function

restructuredtext_lint.lint(content, filepath=None)

Lint reStructuredText and return errors

  • content String - reStructuredText to be linted
  • filepath String - Optional path to file, this will be returned as the source

Returns:

  • errors List - List of errors
    • Each error is a class from docutils with the following attrs
      • line Integer - Line where the error occurred
      • source String - filepath provided in parameters
      • level Integer - Level of the warning
        • Levels represent ‘info’: 1, ‘warning’: 2, ‘error’: 3, ‘severe’: 4
      • type String - Noun describing the error level
        • Levels can be ‘INFO’, ‘WARNING’, ‘ERROR’, or ‘SEVERE’
      • message String - Error message
      • full_message String - Error message and source lines where the error occurred
    • It should be noted that level, type, message, and full_message are custom attrs added onto the original system_message

Examples

Here is an example of all invalid properties

rst = """
Some content.

Hello World
=======
Some more content!
"""
errors = restructuredtext_lint.lint(rst, 'myfile.py')
errors[0].line  # 5
errors[0].source  # myfile.py
errors[0].level  # 2
errors[0].type  # WARNING
errors[0].message  # Title underline too short.
errors[0].full_message  # Title underline too short.
                        #
                        # Hello World
                        # =======
