|
|
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. |
