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

|
73 | Example: load and use the matcher extension with defaults. |
