#! perl -w
# Author: Bert Muennich
# Website: http://www.github.com/muennich/urxvt-perls
# Based on: http://www.jukie.net/~bart/blog/urxvt-url-yank
# Version: git-20120120
# License: GPLv2
# Use keyboard shortcuts to select URLs.
# This should be used as a replacement for the default matcher extension,
# it also makes URLs clickable with the middle mouse button.
# Usage: put the following lines in your .Xdefaults/.Xresources:
# URxvt.perl-ext-common: ...,url-select
# URxvt.keysym.M-u: perl:url-select:select_next
# Use Meta-u to activate URL selection mode, then use the following keys:
# j/k: Select next downward/upward URL (also with arrow keys)
# g/G: Select first/last URL (also with home/end key)
# o/Return: Open selected URL in browser, Return: deactivate afterwards
# y: Copy (yank) selected URL and deactivate selection mode
# q/Escape: Deactivate URL selection mode
# Options:
# URxvt.urlLauncher: Browser/command to open selected URL with
# URxvt.underlineURLs: If set to true, all URLs get underlined
# URvxt.urlButton: Mouse button to click-open URLs (default: 2)
