walker

A simple nodejs directory walker. It's not very featureful; this demonstrates the entire API:

Walker('/etc/')
  .filterDir(function(dir) {
    if (dir === '/etc/pam.d') {
      console.warn('Skipping /etc/pam.d and children')
      return false
    }
    return true
  })
  .on('dir', function(dir) {
    console.log('Got directory: ' + dir)
  })
  .on('file', function(file) {
    console.log('Got file: ' + file)
  })
  .on('error', function(er, target, stat) {
    console.log('Got error ' + er + ' on target ' + target)
  })
  .on('end', function(file) {
    console.log('Walker is done.')
  })

You specify a root directory to walk and optionally specify a function to prune sub-directory trees via the filterDir function. The Walker exposes a number of events, broadcasting each directory, file, error and finally the event to signal the end of the process.

TODO

• Better symlink support.
