This is a simple weechat plugin that allows you to pipe buffers through urlview. This gives you an interactive list of URLs to open, which is especially helpful if there are multiple URLs in the buffer making urlgrab hard to use.

Copy the script to ~/.weechat/python/autoload

mkdir -p ~/.weechat/python/autoload
wget https://raw.githubusercontent.com/keith/urlview-weechat/master/urlview.py ~/.weechat/python/autoload

This is a python rewrite of this ruby plugin
