12 | =head1 NAME |
|
|
13 | |
|
|
14 | matcher - match strings in terminal output and change their rendition |
|
|
15 | |
|
|
16 | =head1 DESCRIPTION |
|
|
17 | |
|
|
18 | Uses per-line display filtering (C<on_line_update>) to underline text |
|
|
19 | matching a certain pattern and make it clickable. When clicked with the |
|
|
20 | mouse button specified in the C<matcher.button> resource (default 2, or |
|
|
21 | middle), the program specified in the C<matcher.launcher> resource |
|
|
22 | (default, the C<url-launcher> resource, C<sensible-browser>) will be started |
|
|
23 | with the matched text as first argument. The default configuration is |
|
|
24 | suitable for matching URLs and launching a web browser, like the |
|
|
25 | former "mark-urls" extension. |
|
|
26 | |
|
|
27 | The default pattern to match URLs can be overridden with the |
|
|
28 | C<matcher.pattern.0> resource, and additional patterns can be specified |
|
|
29 | with numbered patterns, in a manner similar to the "selection" extension. |
|
|
30 | The launcher can also be overridden on a per-pattern basis. |
|
|
31 | |
|
|
32 | It is possible to activate the most recently seen match or a list of matches |
|
|
33 | from the keyboard. Simply bind a keysym to "matcher:last" or |
|
|
34 | "matcher:list" as seen in the example below. |
|
|
35 | |
|
|
36 | Example: load and use the matcher extension with defaults. |
|
|
37 | |
|
|
38 | URxvt.perl-ext: default,matcher |
|
|
39 | |
|
|
40 | Example: use a custom configuration. |
|
|
41 | |
|
|
42 | URxvt.url-launcher: sensible-browser |
|
|
43 | URxvt.keysym.C-Delete: matcher:last |
|
|
44 | URxvt.keysym.M-Delete: matcher:list |
|
|
45 | URxvt.matcher.button: 1 |
|
|
46 | URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-] |
