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 "matcher:last" or
34"matcher:list" as seen in the example below.
35
36The 'matcher:select' action enables a mode in which it is possible to
37iterate over the matches using the keyboard and either activate them
38or copy them to the clipboard. While the mode is active, normal terminal
39input/output is suspended and the following bindings are recognized:
40
41=over 4
42
43=item C<Up>
44
45Search for a match upwards.
46
47=item C<Down>
48
49Search for a match downwards.
50
51=item C<Home>
52
53Jump to the topmost match.
54
55=item C<End>
56
57Jump to the bottommost match.
58
59=item C<Escape>
60
61Leave the mode and return to the point where search was started.
62
63=item C<Enter>
64
65Activate the current match.
66
67=item C<y>
68
69Copy the current match to the clipboard.
70
71=back
72
73Example: load and use the matcher extension with defaults.

75 URxvt.perl-ext: default,matcher

77Example: use a custom configuration.
