12=head1 NAME
13
14matcher - match strings in terminal output and change their rendition
15
16=head1 DESCRIPTION
17
18Uses per-line display filtering (C<on_line_update>) to underline text
19matching a certain pattern and make it clickable. When clicked with the
20mouse button specified in the C<matcher.button> resource (default 2, or
21middle), the program specified in the C<matcher.launcher> resource
22(default, the C<url-launcher> resource, C<sensible-browser>) will be started
23with the matched text as first argument. The default configuration is
24suitable for matching URLs and launching a web browser, like the
25former "mark-urls" extension.
26
27The default pattern to match URLs can be overridden with the
28C<matcher.pattern.0> resource, and additional patterns can be specified
29with numbered patterns, in a manner similar to the "selection" extension.
30The launcher can also be overridden on a per-pattern basis.
31
32It is possible to activate the most recently seen match or a list of matches
33from the keyboard. Simply bind a keysym to "perl:matcher:last" or
34"perl:matcher:list" as seen in the example below.
35
36Example: load and use the matcher extension with defaults.
37
38 URxvt.perl-ext: default,matcher
39
40Example: use a custom configuration.
