|
7 | selection-autotransform - automatically transform select text |
|
|

|
|
9 | =head1 DESCRIPTION |
|
|
10 | |
|
|
11 | This selection allows you to do automatic transforms on a selection |
|
|
12 | whenever a selection is made. |
|
|
13 | |
|
|
14 | It works by specifying perl snippets (most useful is a single C<s///> |
|
|
15 | operator) that modify C<$_> as resources: |
|
|
16 | |
|
|
17 | URxvt.selection-autotransform.0: transform |
|
|
18 | URxvt.selection-autotransform.1: transform |
|
|
19 | ... |
|
|
20 | |
|
|
21 | For example, the following will transform selections of the form |
|
|
22 | C<filename:number>, often seen in compiler messages, into C<vi +$filename |
|
|
23 | $word>: |
|
|
24 | |
|
|
25 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/ |
|
|
26 | |
|
|
27 | And this example matches the same,but replaces it with vi-commands you can |
|
|
28 | paste directly into your (vi :) editor: |
|
|
29 | |
|
|
30 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/ |
|
|
31 | |
|
|
32 | Of course, this can be modified to suit your needs and your editor :) |
|
|
33 | |
|
|
34 | To expand the example above to typical perl error messages ("XXX at |
|
|
35 | FILENAME line YYY."), you need a slightly more elaborate solution: |
|
|
36 | |
|
|
37 | URxvt.selection.pattern-0: ( at .*? line \\d+[,.]) |
|
|
38 | URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/ |
|
|
39 | |
|
|
40 | The first line tells the selection code to treat the unchanging part of |
|
|
41 | every error message as a selection pattern, and the second line transforms |
|
|
42 | the message into vi commands to load the file. |
|
|

46 | sub msg { |

47 | my ($self, $msg) = @_; |

50 | $overlay->set (0, 0, $msg); |
| 10 | my $iow; $iow = urxvt::timer->new->after (2)->cb (sub { |
51 | $self->{timer} = urxvt::timer->new->after (2)->cb (sub { |
|
|
52 | delete $self->{timer}; |
