=head1 DESCRIPTION |
17 |
root |
1.10 |
|
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 |
sf-exg |
1.16 |
(default, the C<url-launcher> resource, C<sensible-browser>) will be started |
23 |
root |
1.10 |
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 |
sf-exg |
1.20 |
from the keyboard. Simply bind a keysym to "matcher:last" or |
34 |
|
|
"matcher:list" as seen in the example below. |
35 |
root |
1.10 |
|
36 |

1.14 |
Example: load and use the matcher extension with defaults. |
