GitHub Action

If you want an easy way to test your repository spelling (or a subset of files) you can use the Typos Action! It is served from this repository, and can easily be used as follows:

name: Test GitHub Action
on: [pull_request]

jobs:
  run:
    name: Spell Check with Typos
    runs-on: ubuntu-latest
    steps:
    - name: Checkout Actions Repository
      uses: actions/checkout@v4

    - name: Check spelling of file.txt
      uses: crate-ci/typos@master
      with:
        files: ./file.txt

    - name: Use custom config file
      uses: crate-ci/typos@master
      with:
        files: ./file.txt
        config: ./myconfig.toml

    - name: Ignore implicit configuration file
      uses: crate-ci/typos@master
      with:
        files: ./file.txt
        isolated: true

    - name: Writes changes in the local checkout
      uses: crate-ci/typos@master
      with:
        write_changes: true

Important for any of the examples above, make sure that you choose a release or commit as a version, and not a branch (which is a moving target).

Also make sure when referencing relative file paths to use ./ (e.g., ./file.txt instead of file.txt.

Input

Name	Description	Required	Default
files	Files or patterns to check	false	If not defined, the default set of files are checked
extend_identifiers	Comma separated list of extend identifiers, like someone's name	false	not set
extend_words	Comma separated list of extend words.	false	not set
isolated	Ignore implicit configuration files	false	false
write_changes	Writes changes on the Action's local checkout	false	false
config	Use a custom config file (must exist)	false	not set

write_changes: doesn't commit or push anything to the branch. It only writes the changes locally to disk, and this can be combined with other actions, for instance that will submit code suggestions based on that local diff.
