env

You can specify some ENV variables for the command or script.

Example

# lefthook.yml

pre-commit:
  commands:
    test:
      env:
        RAILS_ENV: test
      run: bundle exec rspec

Extending PATH

If your hook is run by GUI program, and you use some PATH tweaks in your ~/.rc, you might see an error saying executable not found. In that case You can extend the $PATH variable with lefthook-local.yml configuration the following way.

# lefthook.yml

pre-commit:
  commands:
    test:
      run: yarn test

# lefthook-local.yml

pre-commit:
  commands:
    test:
      env:
        PATH: $PATH:/home/me/path/to/yarn

Notes

This option is useful when using lefthook on different OSes or shells where ENV variables are set in different ways.
