files
A custom command executed by the sh shell that returns the files or directories to be referenced in {files} template for run setting.
If the result of this command is empty, the execution of commands will be skipped.
This option overwrites the hook-level files option.
Example
Provide a git command to list files.
# lefthook.yml
pre-push:
  commands:
    stylelint:
      tags:
        - frontend
        - style
      files: git diff --name-only master
      glob: "*.js"
      run: yarn stylelint {files}
Call a custom script for listing files.
# lefthook.yml
pre-push:
  commands:
    rubocop:
      tags: backend
      glob: "**/*.rb"
      files: node ./lefthook-scripts/ls-files.js # you can call your own scripts
      run: bundle exec rubocop --force-exclusion --parallel {files}
