option to ignore directories

[dylang]

Right now depcheck walks every directory except node_modules

finder.on("directory", function (dir) {
    if (path.basename(dir) === "node_modules") {
      return;
    }
    directories.push(dir);
  });

It would be helpful if we could provide an array of directories to ignore so we could avoid scanning our build directory which happens to be huge.

For example

depcheck(root, {
    ignoreDirs: [ 
        // node_modules is assumed
        'build',
        'bower_components'
    ]  
    }, cb);

I thought of a more automatic way to do this...

What do you think about ignoring all files/directories in .gitignore?

I could make a pull request for this if you like the idea.

It's an interesting idea, however, not everyone is using git for their projects, must not forget people using svn, mercurial or any other VCS :)

So yeah, I like the first one better where people can add manually what direcotries depecheck should ignore.

I'm sorry I didn't respond to this issue soone, had plenty of work and not enough time...

Feel free to send a PR if you want this feature to come sooner than later.

Great point about those other source control systems that I tend to forget exist.

Totally understand about not having time, no worries! I'm using your project for a "when I have time" project too, and with two kids and a busy job, it's difficult to find time. I'll try to make a PR but no promises on when I will get it done.

Here's what I've been building: https://github.com/dylang/npm-check

Guess we can close this one thanks to your PR.

Thanks
