gulp-byo-jslint

A bring-your-own JSLint plugin for Gulp.

Isn't there already a JSLint plugin for Gulp?

Yes there is, but it is not awesome. It breaks on the first violation instead of enumerating all warnings, hasn't been updated in a very long time and doesn't support the latest version of JSLint.

What do you mean "BYO"?

Bring-your-own copy of jslint.js, quite literaly. This plugin wont work without it.

The use of git submodules is highly recommended for this. No need to to wait for updates to gulp-byo-jslint for new versions of JSLint. Just git pull in the submodule directory. What better way to stay on the bleeding edge?

md submodules
cd submodules
git submodule add https://github.com/douglascrockford/JSLint.git

Does it support "old" JSLint?

No editions prior to 2015-05-01 will work with this plugin. The JSLint interface changed significantly at that time (all for the better), so there is no going back.

Any current edition of JSLint should work fine.

npm install gulp-byo-jslint --save-dev
