Accessing git hook arguments from files command

[BasixKOR]

I've tried to use post-checkout hook and I tried to diff the changed files using git diff --name-only {1} {0} but I noticed this doesn't work and {files} just printed files.

Closing as it is likely a duplicate of #269.

Hey, @BasixKOR ! Could you provide your lefthook.yml content? #314 fixes the quoting issue on Windows, but does nothing with git arguments like {1} and {0}.

Also {0}, {1}, and other git hook args substitutions don't happen on files parameter, but if you provide a usecase I can add this feature!

Also when you use {0} - it prints all git arguments for the hook. Use {1} for first argument and {2} for the second. See https://github.com/evilmartians/lefthook/blob/master/docs/full_guide.md#git-hook-argument-shorthands-in-commands

Hi @mrexox I was looking for the same thing, I want to perform bundle install in a ruby project whenever a Gemfile is changed. So my idea was something about

post-checkout:
  commands:
    01-bundle-install:
      files: git diff --name-only {1} {2} | grep -i Gemfile
      run: bundle install

But is not working because {1} and {2} are not forwarded to files. Is there any workaround apart from writing a custom script in run that do that?
