As part of tidying up ESLint rules for devtools, we want to de-duplicate the rules - remove rules from devtools/.eslintrc.js that are already defined the same in tools/lint/eslint/eslint-plugin-mozilla/lib/configs/recommended.js.
There's also some now obsolete definitions for rules that can also be removed (they were obsoleted in ESLint 1.x, and we're now on 4.x).

Bug 1430615 - Remove ESLint rules duplicated in devtools/.eslintrc.js where they are already defined in recommended.js.
https://reviewboard.mozilla.org/r/212972/#review218620
Thanks for the cleanup! Some comments and mostly a question about requiring the parent config file.
Would it be fine to add to devtools' eslintrc.js the following property:
"extends": "../.eslintrc.js",
I think a lot of devtools developers have their editor setup to do eslint verification on the fly.
Without this, the editor has no way to know about the rules coming from the top-level eslintrc.

this one is also in recommended js

This is very similar to the current value in recommended.js which is:
"no-mixed-spaces-and-tabs": ["error", "smart-tabs"],
I'm not sure how smart-tabs is relevant knowing that we also have no-tabs: "error"?

deprecated, should be removed

I looked at doing this, and it messes up the glob based configurations that we have at the top level. So this isn't a good idea.
If we get specific issues with setups, we'll look at those as they come up.

Oh, thanks for pointing that out. I've filed bug 1431129 for fixing this in recommended.js. I'll drop no-mixed-spaces-and-tabs from here, since the no-tabs rule seems to be covering things anyway.

Looks good to me, thanks!
As discussed on IRC, moving rules to the top level eslintrc means that devs that use Sublime (and maybe other editors?) with /devtools as the root folder of their project can no longer rely on the editor to check those rules.
Will send an email to dev-developer-tools and mention it during our next meeting to broadcast the info.
