Topy

Topy (anagram of "typo") is a Python script to fix typos in text, using rulesets developed by the RegExTypoFix project from Wikipedia. The English ruleset is included with Topy and is used by default. Other rulesets can be manually downloaded.

Topy works with Python 3.7-3.11.

The easiest way to install it is using pip:

pip install topy

Usage:

Usage: topy [options] FILES/DIRS...

Options:
  -h, --help            show this help message and exit
  -q, --quiet           silence information messages
  -a, --apply           overwrite files in place
  -r FILE, --rules=FILE
                        specify custom ruleset file to use
  -d RULE, --disable=RULE
                        disable rules by name
  --color=WHEN, --colour=WHEN
                        colorize the output; WHEN can be 'never', 'always', or
                        'auto'

For example, if you want to integrate topy in your CI pipeline, you can do something like:

sh -c "git ls-files | xargs topy --quiet --apply --; git --no-pager diff --exit-code"

The line above will check all files tracked by git, apply fixes to them and fail if any changes are applied. If no changes are to be applied, the command returns success.

Code style:

• In general follow the Python PEP-8 coding style, except line length can go up to 120 chars.
• Strings that have meaning for humans use double quotes ("), otherwise single quotes ('). When in doubt, don't worry about it.
• Code should be compatible with both Python 2 and 3, preferably without version-specific conditionals.

Run the test suite using python setup.py test.
