pastebin_helper
^^^^^^^^^^^^^^^

The name of a helper executable that should perform pastebin upload on bpython's
behalf. If set, this overrides `pastebin_url`. It also overrides
`pastebin_show_url`, as the helper is expected to return the full URL to the
pastebin as the first word of its output. The data is supplied to the helper via
STDIN.

An example helper program is ``pastebinit``, available for most systems. The
following helper program can be used to create `gists
<http://gist.github.com>`_:

.. code-block:: python

  #!/usr/bin/env python

  import sys
  import urllib2
  import json

  def do_gist_json(s):
      """ Use json to post to github. """
      gist_public = False
      gist_url = 'https://api.github.com/gists'

      data = {'description': None,
              'public': None,
              'files' : {
                  'sample': { 'content': None }
              }}
      data['description'] = 'Gist from BPython'
      data['public'] = gist_public
      data['files']['sample']['content'] = s

      req = urllib2.Request(gist_url, json.dumps(data), {'Content-Type': 'application/json'})
      try:
          res = urllib2.urlopen(req)
      except HTTPError, e:
          return e

      try:
          json_res = json.loads(res.read())
          return json_res['html_url']
      except HTTPError, e:
          return e

  if __name__ == "__main__":
    s = sys.stdin.read()
    print do_gist_json(s)
