How to exclude multiple directories?

[stodge]

You'll have to forgive my ignorance as I don't "get" regexes. How would I exclude multiple directories? I need to exclude all of these directories:

• .hgignore
• bin
• static/extern
• node_modules

... and perhaps more.

Thanks

One way is to use the or operator, e.g. "|", between each filename, but you'd probably want to specify start and end and escape special characters. For the above, this regex should work:

/^(\.hgignore|bin|static\/extern|node_modules)$/

As of version 0.1.5, you can use arrays for the match, exclude, matchDir, and excludeDir options. For your example, you should now be able to implement the above as follows:

dir.readFiles(__dirname, {
    exclude: ['.hgignore', 'bin', 'static/extern', 'node_modules']
    }, function(err, content, next) {
        if (err) throw err;
        console.log('content:', content);
        next();
    },
    function(err, files){
        if (err) throw err;
        console.log('finished reading files:',files);
    }); 

Hopefully this will make working with arbitrary lists of filenames easier when doing matches or excludes.
