# Url shortener for WeeChat by arza <arza@arza.us>, distributed freely and without any warranty, licensed under GPL3 <http://www.gnu.org/licenses/gpl.html>
# Why yet another url shortener script?
# - use your own shortener in a web server, for example: http://weechat.arza.us/url_arza.php
# - a key to shorten url in input line: bind to /url_arza
# - toggle short urls under long urls, not logged: /filter add url_arza * no_log ^^http:// ; /filter toggle url_arza
# - no dependencies
# - simple
# Requires WeeChat >=0.3.6
# Changelog:
# 2013-07-27 0.1: initial release
# 2019-02-10 0.2: support multiple urls per line, fix default values, fix truncated prefix, increase timeout, simplify
