13=head1 NAME
14
15matcher - match strings in terminal output and change their rendition
16
17=head1 DESCRIPTION
18
19Uses per-line display filtering (C<on_line_update>) to underline text
20matching a certain pattern and make it clickable. When clicked with the
21mouse button specified in the C<matcher.button> resource (default 2, or
22middle), the program specified in the C<matcher.launcher> resource
23(default, the C<url-launcher> resource, C<sensible-browser>) will be started
24with the matched text as first argument. The default configuration is
25suitable for matching URLs and launching a web browser, like the
26former "mark-urls" extension.
27
28The default pattern to match URLs can be overridden with the
29C<matcher.pattern.0> resource, and additional patterns can be specified
30with numbered patterns, in a manner similar to the "selection" extension.
31The launcher can also be overridden on a per-pattern basis.
32
33It is possible to activate the most recently seen match or a list of matches
34from the keyboard. Simply bind a keysym to "matcher:last" or
35"matcher:list" as seen in the example below.
36
37The C<matcher:select> action enables a mode in which it is possible to
38iterate over the matches using the keyboard and either activate them
39or copy them to the clipboard. While the mode is active, normal terminal
40input/output is suspended and the following bindings are recognized:
41
42=over 4
43
44=item C<Up>
45
46Search for a match upwards.
47
48=item C<Down>
49
50Search for a match downwards.
51
52=item C<Home>
53
54Jump to the topmost match.
55
56=item C<End>
57
58Jump to the bottommost match.
59
60=item C<Escape>
61
62Leave the mode and return to the point where search was started.
63
64=item C<Enter>
65
66Activate the current match.
67
68=item C<y>
69
70Copy the current match to the clipboard.
71
72=back
73
74It is also possible to cycle through the matches using a key
75combination bound to the C<matcher:select> action.
76
77Example: load and use the matcher extension with defaults.
78
79 URxvt.perl-ext: default,matcher
80
81Example: use a custom configuration.
