linter-flow

Lightweight alternative to Facebook's Flow plugin for facebook/flow.

linter-demo

Installation

  • Install flow
  • flow init
  • apm install linter-flow

Settings

You can configure linter-flow by editing ~/.atom/config.cson (choose Open Your Config in Atom menu) or in Preferences:

'linter-flow':
  'executablePath': 'flow'
  'enableAll': false
  • executablePath: Absolute path to the Flow executable on your system.
  • enableAll: Typecheck all files, not just file containing @flow.

Why not X?

linter-flow is made to be a lightweight package that does one thing well.

  1. A similarly named package: linter-flow-plus is now a mirror. The development happens for both packages in parallel.
  2. IDE-flow works relatively well, but it doesn't lint on-the-fly and doesn't integrate with the linter package.
  3. Nuclide has too many problems for now to be reliable. It also involves installing a large number of other packages.

Please Note: IDE-flow and Nuclide provide other features such as autocomplete, type definitions on hover etc. Please continue to use those services for those features. (possibly in addition to linter-flow)

Limitations

This linter currently does not support Hack. Though the linter just uses the flow-cli and hack support should be trivial to add, I'm not a Hack/PHP developer and I can't test that it actually works. I would welcome if someone was to add support for Hack to this package and test it.

Contributing

If you would like to contribute enhancements or fixes, please do the following:

  1. Fork the plugin repository
  2. Hack on a separate topic branch created from the latest master
  3. Commit and push the topic branch
  4. Make a pull request
  5. Welcome to the club!

Please note that modifications should follow these coding guidelines:

  • Indent is 2 spaces with .editorconfig
  • Code should pass eslint linter with the provided .eslintrc
  • Vertical whitespace helps readability, don’t be afraid to use it

Thank you for helping out!
