Support formatting multiple files in a single command

[kevgo]

Thanks for building and maintaining Ghokin, I use it almost every day and really appreciate the work that goes into it. ❤️ 🙏

Currently, Ghokin accepts only a single file or directory path per invocation. It would be useful to support passing multiple .feature files, for example:

ghokin fmt replace path/to/one.feature path/to/two.feature

Use case

I'd like to run Ghokin only against .feature files changed on the current Git branch, rather than formatting the entire repository. This allows introducing Ghokin gradually on a large legacy codebase with a different Gherkin style, and makes formatting faster.

Would you be open to supporting multiple file paths as positional arguments?

Hi,
Thanks for the good vibe, really appreciated 👍
Why not scripting your usage with a bash script or something like this ?

[kevgo]

Invoking Ghokin separately for each file adds noticeable overhead. I run Ghokin concurrently with formatters for other file types to format all changed files as quickly as possible. Life is too short to wait for tooling 😄

I think it should not be a big deal to implement, I can check. I'm not really convinced of the usage though, for me either you check a file for some reasons or your want to format all files at once in a folder.

Some use cases for supporting multiple explicit files:

• On a feature branch, format only the .feature files changed on that branch.
• In a pre-commit hook, format only staged .feature files.
• In an IDE integration, format only the files currently open.
• During a gradual migration between formatters, format only the files or directories assigned to Ghokin.
• Format all files except those with custom formatting Ghokin does not support yet.
• Integrate Ghokin into tooling that discovers files, categorizes and filters them, then runs multiple formatters concurrently after verifying that each formatter operates on a disjoint set of files.

A formatter cannot anticipate every environment or workflow in which it will be used. Providing a flexible, composable interface allows callers to implement these policies themselves rather than requiring Ghokin to support each use case directly.

Ghokin already supports several useful input modes:

• STDIN
• a single file
• all files in a directory

The missing case is an explicit list of files. Supporting multiple file arguments seems like a natural extension of the existing interface and consistent with Ghokin's current scope.
