matcher - match strings in terminal output and change their rendition |

=head1 DESCRIPTION |
18 |
root |
1.10 |
|
19 |
|
|
Uses per-line display filtering (C<on_line_update>) to underline text |
20 |
|
|
matching a certain pattern and make it clickable. When clicked with the |
21 |
|
|
mouse button specified in the C<matcher.button> resource (default 2, or |
22 |
|
|
middle), the program specified in the C<matcher.launcher> resource |
23 |
sf-exg |
1.16 |
(default, the C<url-launcher> resource, C<sensible-browser>) will be started |
24 |
root |
1.10 |
with the matched text as first argument. The default configuration is |
25 |
|
|
suitable for matching URLs and launching a web browser, like the |
26 |
|
|
former "mark-urls" extension. |
27 |
|
|
|
28 |
|
|
The default pattern to match URLs can be overridden with the |
29 |
|
|
C<matcher.pattern.0> resource, and additional patterns can be specified |
30 |
|
|
with numbered patterns, in a manner similar to the "selection" extension. |
31 |
|
|
The launcher can also be overridden on a per-pattern basis. |
32 |
|
|
|
33 |
|
|
It is possible to activate the most recently seen match or a list of matches |
34 |
sf-exg |
1.20 |
from the keyboard. Simply bind a keysym to "matcher:last" or |
35 |
|
|
"matcher:list" as seen in the example below. |
36 |
root |
1.10 |
|
37 |
sf-exg |
1.35 |
The C<matcher:select> action enables a mode in which it is possible to |
38 |
sf-exg |
1.31 |
iterate over the matches using the keyboard and either activate them |
39 |
|
|
or copy them to the clipboard. While the mode is active, normal terminal |
40 |
|
|
input/output is suspended and the following bindings are recognized: |
41 |
|
|
|
42 |
|
|
=over 4 |
43 |
|
|
|
44 |
|
|
=item C<Up> |
45 |
|
|
|
46 |
|
|
Search for a match upwards. |
47 |
|
|
|
48 |
|
|
=item C<Down> |
49 |
|
|
|
50 |
|
|
Search for a match downwards. |
51 |
|
|
|
52 |
|
|
=item C<Home> |
53 |
|
|
|
54 |
|
|
Jump to the topmost match. |
55 |
|
|
|
56 |
|
|
=item C<End> |
57 |
|
|
|
58 |
|
|
Jump to the bottommost match. |
59 |
|
|
|
60 |
|
|
=item C<Escape> |
61 |
|
|
|
62 |
|
|
Leave the mode and return to the point where search was started. |
63 |
|
|
|
64 |
|
|
=item C<Enter> |
65 |
|
|
|
66 |
|
|
Activate the current match. |
67 |
|
|
|
68 |
|
|
=item C<y> |
69 |
|
|
|
70 |
|
|
Copy the current match to the clipboard. |
71 |
|
|
|
72 |
|
|
=back |
73 |
|
|
|
74 |
sf-exg |
1.35 |
It is also possible to cycle through the matches using a key |
75 |
|
|
combination bound to the C<matcher:select> action. |
76 |
|

|
77 |
