-# 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.url-select.autocopy: If true, selected URLs are copied to PRIMARY
-# URvxt.url-select.button: Mouse button to click-open URLs (default: 2)
-# URxvt.url-select.launcher: Browser/command to open selected URL with
-# URxvt.url-select.underline: If set to true, all URLs get underlined
-
-use strict;
-
-# The custom rendition bit to use for marking the cell as being underlined
-# by us so we can unset it again after a line has changed.
-use constant UNDERLINED => 1<<3; # arbitrarily chosen in hope of no collision
