Better support for linting multiple files

[adidahiya]

Related: #680

• if given a directory, TSLint should recursively search for .ts{,x} files in that directory and add them to be linted (similar to ESLint)
  • implemented here: Directories support #857
• if provided the path to a tsconfig.json file, TSLint should lint all the files listed in the "files" list and files they reference via imports or references
  • Q: should we ignore .d.ts files by default? and provide an option to opt-in to linting them?
  • Q: should this be the default if no files are specified? i.e. TSLint searches for a tsconfig.json file in the same way it currently searches for a tslint.json file
  • moved to Supply files to lint in tsconfig.json #858
• support globs in CLI on Windows (Can't use a glob in the CLI on Windows #688, Glob in the CLI #779)
  • implemented here: Better support for globs in cli #827

Q: should we ignore .d.ts files by default? and provide an option to opt-in to linting them?

Yes please. Getting lint errors because the typings from tsd doesn't follow the same code standard as the project would be pretty messy.
An opt-out would work as well, but I think the most common would be to not wanting to lint .d.ts files.

TSLint should lint all the files listed in the "files"

Are you going to support filesGlob and exclude from tsconfig as well as files?
This would be very helpful, as it is wierd and close to impossible to define all the sources in files in large projects.

@raveclassic Definitely want to support filesGlob and exclude. Without those things are significantly more painful

@jkillian Thanks, waiting for changes. For now will use gulp to gather the files.
Besides, great work guys!

I wonder what's the benefit of merging multiple reports into one... I think that three (relatively) small issues have a greater chance to be implemented than one big issue. But sure, it's up to you how you manage your project...

I have an unfinished solution for task 2 and #680 in here. I don't have enough time to finish it so if anyone would like to step in feel free to do so.

BTW, after #857 is merged I feel that this one should be closed. Task 2 isn't relevant here.

[adidahiya]

moved task 2 (tsconfig.json support) to #858

I agree with ignoring .d.ts files by default

Please do not do that, at least not hard coding that. Using tslint to lint .d.ts for typings.

No one is really pining for directories support (first checklist item in the issue description) so it seems like globs are enough. Closing this out.
