I wanted to share clean URL's directly from my phone. This is most specifically geared towards feedburner URL's, but could be just short URL's as well. This script unwraps any URL's surrounded with ** in the text on your clipboard. Unwraps them, and clears out unwanted query params. Then opens the text in felix for posting.

expandurl.py

import clipboard
import requests
import webbrowser
import urlparse
from urllib import quote, urlencode

blacklist_query_params = ['utm_campaign', 'utm_source', 'utm_medium']
text = clipboard.get()
if text == '':
    print 'No text in clipboard'

if '**' in text:
    start, url, end = text.split('**')
    resp = requests.get(url)
    if resp.ok:
        url = resp.url

    parts = urlparse.urlsplit(url)
    query = urlparse.parse_qs(parts.query)
    for bkey in blacklist_query_params:
        try:
            del query[bkey]
        except KeyError:
            pass
    parts = list(parts)
    parts[3] = urlencode(query)
    url = urlparse.urlunsplit(parts)

    text = ''.join([start, url, end])

q = quote(text)
webbrowser.open('felix://compose/post?text=' + q)
