13 | =head1 NAME |
|
|
14 | |
|
|
15 | matcher - match strings in terminal output and change their rendition |
|
|
16 | |
|
|
17 | =head1 DESCRIPTION |
|
|
18 | |
|
|
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 | (default, the C<url-launcher> resource, C<sensible-browser>) will be started |
|
|
24 | 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 | from the keyboard. Simply bind a keysym to "matcher:last" or |
|
|
35 | "matcher:list" as seen in the example below. |
|
|
36 | |
|
|
37 | The C<matcher:select> action enables a mode in which it is possible to |
|
|
38 | 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 |
|
|
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 | It is also possible to cycle through the matches using a key |
|
|
75 | combination bound to the C<matcher:select> action. |
|
|
76 | |
|
|
77 | Example: load and use the matcher extension with defaults. |
|
|
78 | |
|
|
79 | URxvt.perl-ext: default,matcher |
|
|
80 | |
|
|
81 | Example: use a custom configuration. |
|
|
82 | |
|
|
83 | URxvt.url-launcher: sensible-browser |
|
|
84 | URxvt.keysym.C-Delete: matcher:last |
|
|
85 | URxvt.keysym.M-Delete: matcher:list |
|
|
86 | URxvt.matcher.button: 1 |
|
|
87 | URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-] |
|
|
88 | URxvt.matcher.pattern.2: \\B(/\\S+?):(\\d+)(?=:|$) |
|
|
89 | URxvt.matcher.launcher.2: gvim +$2 $1 |
|

|
91 | =head2 Regex encoding/wide character matching |
|
|
92 | |
|
|
93 | Urxvt stores all text as unicode, in a special encoding that uses |
|
|
94 | one character/code point per column. For various reasons, the regular |
|
|
95 | expressions are matched directly against this encoding, which means there are a few things |
|
|
96 | you need to keep in mind: |
|
|
97 | |
|
|
98 | =over |
|
|
99 | |
|
|
100 | =item X resources/command line arguments are locale-encoded |
|
|
101 | |
|
|
102 | The regexes taken from the command line or resources will be converted |
|
|
103 | from locale encoding to unicode. This can change the number of code points |
|
|
104 | per character. |
|
|
105 | |
|
|
106 | =item Wide characters are column-padded with C<$urxvt::NOCHAR> |
|
|
107 | |
|
|
108 | Wide characters (such as kanji and sometimes tabs) are padded with |
|
|
109 | a special character value (C<$urxvt::NOCHAR>). That means that |
|
|
110 | constructs such as C<\w> or C<.> will only match part of a character, as |
|
|
111 | C<$urxvt::NOCHAR> is not matched by C<\w> and both only match the first |
|
|
112 | "column" of a wide character. |
|
|
113 | |
|
|
114 | That means you have to incorporate C<$urxvt::NOCHAR> into parts of regexes |
|
|
115 | that may match wide characters. For example, to match C<\w+> you might |
|
|
116 | want to use C<[\w$urxvt::NOCHAR]+> instead, and to match a single character |
|
|
117 | (C<.>) you might want to use C<.$urxvt::NOCHAR*> instead. |
