A spell checker plugin for MkDocs.

This plugin can use different backends to check the spelling of words in your final HTML pages. These backends are:

• codespell
• symspellpy

To install all backends, use the all extra. Otherwise specify the name(s) of the backend(s) as extra.

pip install 'mkdocs-spellcheck[all]'
pip install 'mkdocs-spellcheck[codespell]'
pip install 'mkdocs-spellcheck[symspellpy]'
pip install 'mkdocs-spellcheck[codespell,symspellpy]'

# mkdocs.yml
plugins:
- search
- spellcheck:
    backends:  # the backends you want to use
    - symspellpy  # as strings
    - codespell:  # or nested configs
        dictionaries: [clear, rare]
    # known_words can also be a list of words
    known_words: known_words.txt
    # ignore words in <code> tags
    ignore_code: yes
    # minimum length of words to consider
    min_length: 2
    # maximum number of capital letters in a word
    max_capital: 1
    # keep unicode characters
    allow_unicode: no
    # skip files entirely (supports Unix shell-style wildcards)
    skip_files:
    - credits.md
    - coverage.md
    - reference/*
    # whether to only check in strict mode
    strict_only: yes

By default, the symspellpy backend is used.

Once your configuration is ready, just run mkdocs build -s to check the spelling inside your pages.

The builtin dictionaries are:

• clear for unambiguous errors
• rare for rare (but valid) words that are likely to be errors
• informal for making informal words more formal
• usage for replacing phrasing with recommended terms
• code for words from code and/or mathematics that are likely to be typos in other contexts (such as uint)
• names for valid proper names that might be typos
• en-GB_to_en-US for corrections from en-GB to en-US
