Javascript validation with Tern lint

[angelozerr]

Hi bracket guys,

I would like to know if could interest to work together about managing validation with Tern? The basic idea is to provide a tern plugin to use the file ast and validate the JS file. I have started to implement a simple POC which validates the property of object (ex : document.getEl add a warn message which says "getEl" is a unknown property).

Here a screenshot with CodeMirror :

I have spoken about this feature to Marijn but he wishes not to integrate it to tern, because he has no time to maintain it. See my message at https://groups.google.com/forum/#!topic/codemirror/uHgcDjh6yRc

Hope this idea could interest you.

Hi Angelo,

This would be an interesting experiment, but there will likely be some issues because of how dynamic JS is. It's hard to know for sure when something is defined or not.

I'd suggest bringing this up on the brackets-dev googlegroup to see if there are others who want to explore this with you. (I've also given this issue the Extension Idea label which some people search for when looking for things to build)

Cool! Definitely bring it up on brackets-dev when you want to share it more broadly!

Jus for your information, I have created https://github.com/angelozerr/tern.lint project. It contains both tern lint plugin and CodeMirror lint addon which uses this tern lint plugin.

Any contribution are welcome!
