The Ruby bundle currently supports reformatting a file with RuboCop (“Reformat Document”), and checking the document’s syntax using `ruby -wc.

So far there is no support for automatically checking (or maybe even reformatting) a file everytime it is saved.

For RuboCop, there are (at least) four stand-alone RuboCop bundles providing additional features:

• https://github.com/fazibear/Rubocop.tmbundle https://github.com/fazibear/Rubocop.tmbundle
• https://github.com/mrdougal/textmate2-rubocop https://github.com/mrdougal/textmate2-rubocop
• https://github.com/goyox86/rubocop-tmbundle https://github.com/goyox86/rubocop-tmbundle
• https://github.com/noniq/RuboCop.tmbundle https://github.com/noniq/RuboCop.tmbundle (Disclaimer: This bundle was written by me).

Recently various alternatives to RuboCop emerged, especially:

• https://github.com/testdouble/standard https://github.com/testdouble/standard (uses RuboCop internally, “No configuration“)
• https://github.com/samphippen/rubyfmt https://github.com/samphippen/rubyfmt (autoformatting only, optimized for speed)

Both tools are still pre-1.0, but actively developed.

I’d like to add support for both standardrb and rubyfmt to TextMate. However, I’m not yet sure about the following questions:

• Should the Ruby bundle be extended to support these? Or should one or more stand-alone bundles be created?
• What would be the best way to tell TextMate which (if any) linting / formatting tool it should use for a given ruby file or project?

What’s the goal here? Are standard https://github.com/testdouble/standard or rubyfmt https://github.com/samphippen/rubyfmt better than RoboCop? Because it’s pretty straightforward to make an existing command executed on save.

Assuming we want to add support for these tools I would say they should live in the Ruby bundle. But at the same time if you want to support both it gets slightly more complicated.

Usually when a TextMate bundle executes a command it’s expected to be available in the PATH or it can also check for a specific environment variable, like TM_RUBY.

Since these new tools seem to not be ready for day to day use, I recommend they be turned off by default. This can be configured via another environment variable that can be placed inside .tm_properties to enable.
