Regex functions throw errors

[bryanjos]

This has to do with the :re module not being implemented yet. Issue #306 catalogs what erlang modules and functions need to be implemented

Thanks for the info. I started implementing :re.run but got stuck trying to decipher the javascript representation of the regex object. The elixir code is:

Regex.replace(~r/foo/i, "hello foo", "world")

and the regex in run looks like this:

function run(subject, regex, options) {
  console.log(regex)
  // => Tuple {values: Array(5), length: 5}
  console.log(regex.values)
  // => [Symbol(re_pattern), 0, 0, 0, "ERCPM�������������������f�o�������@�������������������������������	�f�o�ox�	�"]
}

Any idea how I can extract a meaningful value from that? Thanks in advance.

That's odd. Nothing off the top of my head. That must be the binary representation. It's possible the BitString JavaScript module may be able to make something out of it.
