Remove ignore paths from .json

[desandro]

For #88, this adds ignore property to JSON.

This works by deleting and ignored filepaths after the package has been installed.

Tests added. Note added in the README.

I feel pretty good about this, but I'd appreciate @satazor taking a look at the code.

I think we must enable the dot: true option so that glob matches the .git and other files that start with a .. If it' s not actually removing the .git folder (wich I think it's not) can you add a test for it?

[satazor]

Looks great @desandro, please review what I've mentioned.

[desandro]

Good call for both. Added test for .git directory, and made the push.apply change

[satazor]

@desandro We still have to turn on the dot option on glob (which will also activate it in the minimatch). Will quote the documentation of minimatch:

dot

Allow patterns to match filenames starting with a period, even if the pattern does not explicitly have a period in that spot.

Note that by default, a/**/b will not match a/.d/b, unless dot is set.

This means that if an user types test/**/* as the ignore pattern and there is a test/.jshintrc file, it won't be ignored unless we use dot: true.

If you add a test for this, it will probably fail.

I don't really get the point of asking package creator to "blacklist" unnecessary files. It would be much easier for them to point to the files/directory to be kept. The other way around seems way clearer.

Plus, instead of deleting the downloaded files, you could just keep the full repo copy in the cache, then you copy "whitelisted" files over to the project.

Also, I think this should be over-writable by the end user. So let's say a user want to get twitter bootstrap, but only the modal module, he could easily just pick the file he needs.

[desandro]

@SBoudrias I totally get your point. This seems backwards. Especially for us to implement. But using ignore is a bit friendlier to package developers. There's already a convention for ignore property. It follows same thinking with .gitignore or npm's ignore.

As for user-overwritability of ignore, let's leave that to another issue in the future.

[desandro]

Dang, you're good. dot: true option added, which resolves the test cases for dot dirs/files.

[satazor]

@desandro I know that ahahah :P, joking

Thanks!
