Need equivalent to .jshintignore file

[ilyavolodin]

Need to be able to exclude certain files and sub-directories from eslint when feeding it a directory. I though we already have this feature, but looking through the issues and the code, I don't see it. defiantly need this for web-site linting (excluding vendor sub-directory, for example). It should support globs as exclusion patterns. Might also want to support .jshintignore files directly as well, to make it easier for people transitioning from jshint.

I think I would actually like it to be an option in .eslintrc file instead of a whole new file all together. Thoughts? We can also still support .jshintignore files as well.

Putting it in .eslintrc might complicate things when you have multiple
nested .eslintrc files in several directories. It could be problematic to
get the correct path evaluated in that regard.

Having a top-level .eslintignore seems like a simpler way to handle it, IMO.

As far as I remember, jshint allows you to put .jshintignore files into any directory, it doesn't have to be at the top level, and if nested each one applies to the directory that it's in and all subdirectories. I think that's probably the right way to do this, however, you are correct, that it does complicate things quite a bit.

Up to you what you'd like to do. If you're passionate about this, we can schedule it for a milestone. If you'd rather backlog it, let me know.

I'll see what I can do on the weekend. I think I would rather have exclusions in .eslintrc file. No need for extra file, just to exclude stuff from linting.

After writing all the code for this, I realized that .eslint wouldn't work for this. Ignore file should contain globs based on the directory that it's in, however, config file can be passed to cli from any location. In that case, it's not clear how to resolve globs inside of it. I guess .eslintignore would be the right thing to do.
