Here's a little CoffeeScript routine that will recursively read the file-system, generating an object that represents a complete directory tree. This gist should be executable. You can run it with: `coffee directory-reader.coffee [FILENAME]` to dump a JSON representation of the object to stdout.
# Here's a little CoffeeScript routine that will recursively
# read the file-system, generating an object that represents
# a directory tree.
# The returned object will contain the following attributes:
#
# * `file` - the basename of the file.
# * `dir` - the directory containing the file.
# * `types` - an array containing zero or more of
# "File", "Directory", "SymbolicLink", "BlockDevice",
# "CharacterDevice", "FIFO" or "Socket".
# * `children` - when the "file" is a directory, this will be an
# array of nodes like this one, representing
# the items within the directory.
