Add option "Disable when no .babelrc file in path" about language-babel

[gandm]

The plugin only runs when js files are in the Babel Source Path directory within a project directory. Isn't this good enough? If I do this then I have to traverse all the paths from source back to root looking for .babelrc files on every save.

I'm not sure how other plugin creators have optimized their plugin to avoid frequent lookups. But having to modify settings to ignore or include all my present and future project isn't manageable.
.babelrc detection is much more convenient.

Well I can't cache it as the editor may be open for long periods. I could easily put this in but I have to think about it.

You can add ignore/only regex or globs to .babelrc and this would do it. It is also standard babel practice. Any good?

What linters check for .babelrc?

[louisremi]

Creating a .babelrc in a project where I don't use es6 just so that the plugins ignore everything isn't convenient either.
Here's what linter-eslint package is doing: https://github.com/AtomLinter/linter-eslint/blob/master/lib/linter-eslint.coffee#L52

Ok. They don't seem to check for babelrc, only the linter config file. I have meant to put a language-babel JSON config file that would be read from the project root that overrides the global language Babel settings. This would help. E.g. transpile on save could be overridden per project but the grammar is still active.

My other concern is js files that use Babel register and provide transpile options there.

Maybe I'll put a flag in that checks for babelrc as well as providing a project JSON file for project config settings.

Just published 0.9.0. which has a new flag that suppresses transpile if no .babelrc is in any directory along source path.

\o/ Yay you!

[gandm]

Yeah but I just screwed the deprecation of some unused configs. Will have to pub another release!
