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

|
|
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. |
|
|
43 | |
|
|
44 | =cut |

45 | |
| 5 | sub msg { |
46 | sub msg { |
| 6 | my ($self, $msg) = @_; |
47 | my ($self, $msg) = @_; |
| 7 | |
48 | |
| 8 | my $overlay = $self->overlay (0, 0, $self->strwidth ($msg), 1); |
49 | my $overlay = $self->overlay (0, 0, $self->strwidth ($msg), 1); |
| … | |
… | |
| 14 | } |
55 | } |
| 15 | |
56 | |
| 16 | sub on_init { |
57 | sub on_init { |
| 17 | my ($self) = @_; |
58 | my ($self) = @_; |
| 18 | |
59 | |

60 | for (my $idx = 0; defined (my $res = $self->x_resource ("%.$idx")); $idx++) { |
| 20 | $res = $self->locale_decode ($res); |
61 | $res = $self->locale_decode ($res); |
| 21 | my $transform = eval "sub { $res }"; |
62 | my $transform = eval "sub { $res }"; |
| 22 | |

64 | if ($transform) { |
