Switch ClosureLinter to other linter.

[yosuke-furukawa]

I am watching this discussion, #1243 .
This discussion is not suitable for discuss linter tools.

I have an interest to switch closure-linter to others.

We could not write template string literal in our codes, because closure linter does not recognize new syntax like "". I guess closure linter dose not recognize arrow function =>and generator functionfunction*`.
I think this closure-linter is to be obstacle to change our code to ES6.

So I would like to switch closure-linter to other linters like eslint, jshint.
IMO, I know eslint supports ES6 syntax. http://eslint.org/blog/2014/11/es6-jsx-support/

If @iojs/collaborators agree with this issue, I will send a pull request for this.

@chrisdickinson I guess you also have an interest to switch other linter. #1243 (comment)
This work is great!

+1. However, we have to decide whether we should be able to run the linter without building io.js; the closure linter was written in Python, while both jshint and eslint are in JavaScript.

I'd be ok with only being able to execute things like tests, benchmarks and qa tools after a build.

Yep, the previous status was that we'd be okay switching to eslint / javascript-based tools, since they run after the tests (and thus, we can assume we have at least one working iojs around).

I lean towards eslint (or eslint+jscs), since it's got a pluggable rule system. I have a work in progress branch that switches things over, if anyone would like to take it over. The difficulty was striking a balance between leaning useful rules on and avoiding code churn.

eslint looks pretty flexible. One thing I'd like to avoid is wrapping code in exclusion rules like this:

/* eslint-disable new-cap */
DTRACE_HTTP_CLIENT_REQUEST(this, this.connection);
COUNTER_HTTP_CLIENT_REQUEST();
/* eslint-enable new-cap */

The new-cap rule assumes that the any capitalized variable is a constructor. Maybe the 'pluggable' system would allow us to add special rules like for these DTRACE constants?

Switched closure-linter to eslint! Thanks! f9dd34d 19ffb5c
