We have grunt.file.expand and on top of that, two additional methods (grunt.file.expandFiles and grunt.file.expandDirs) that filter the result file set.

What if those were separate filtering methods?

Instead of this:

var filesOnly = grunt.file.expandFiles('*.*');

A user could do something like this:

var filesAndDirs = grunt.file.expand('*.*');
var filesOnly = grunt.file.files(filesAndDirs);

Hmm, it will still be the same method count though: .expand, .files and .dirs. Question is, will there ever be any need for more filters? I would prefer to stick with convenience methods if there aren't any good reason for splitting them.

The problem I'm running into here is that if I auto-expand wildcard globs in #532, that can only use one of these 3 methods. And it makes sense to use expand there because its results can then be filtered by files or dirs.

I just had an idea:

What if I added an option into the options object for grunt.file.expand called filter whose value could be one of: 'isFile', 'isDirectory', 'isBlockDevice', 'isCharacterDevice', 'isSymbolicLink', 'isFIFO', 'isSocket' (see this)... or a function which was passed a filepath that could return true or false.

Then we could just have one .expand method, and filter results via an option!

This all sounds handy, but shouldn't this wait for 0.5? Lord knows we don't need more features to document right now!


cowboy commented Nov 16, 2012

Sure, this one can wait.


sindresorhus commented Nov 18, 2012

I like it! How about both, either a filter string or a method?

Turns out this didn't wait for 0.5 and was implemented. So closing ;)
