New from Gist

New from Gist.py

# This script downloads and opens a Gist from a URL in the clipboard.
# It's meant to be put in the editor's actions menu.
#
# It works with "raw" and "web" gist URLs, but not with gists that
# contain multiple files or non-Python files.
# 
# If a file already exists, a dialog is shown that asks whether the
# new file should be renamed automatically.

If you change line 36 (the regex) then the ErrorMesage "The Gist could not be downloaded..." should be gone.

gist_id_match = re.match('http(s?)://gist.github.com/([0-9a-zA-Z]*)/([0-9a-f]*)', gist_url)

You also need to change line 39 to get the correct gist id, due to the change of the regex

gist_id = gist_id_match.group(2)

Hope this helps.

Thanks @salomonderossi, I've updated the script with the new regex.

My sense is that it is broken yet again. Line 45 'files' is not a valid key.

I needed to change row 41 to gist_id_match = re.match('http(s?)://gist.github.com/([0-9a-zA-Z])/([0-9a-f])', gist_url)

and row 44 to be gist_id = gist_id_match.group(3)

Why not support multiple files in gist? That might be very helpful when downloading a lib of my own, for instance
