+find them in /usr/local/lib/urxvt/perl/.You can activate them like this:
- rxvt -pe <extensionname>+ urxvt -pe <extensionname>
It also offers the following bindable keyboard command:
+The selection works by trying to match a number of regexes and displaying +them in increasing order of length. You can add your own regexes by +specifying resources of the form:
++ URxvt.selection.pattern-0: perl-regex + URxvt.selection.pattern-1: perl-regex + ...+
The index number (0, 1...) must not have any holes, and each regex must +contain at least one pair of capturing parentheses, which will be used for +the match. For example, the followign adds a regex that matches everything +between two vertical bars:
++ URxvt.selection.pattern-0: \\|([^|]+)\\|+
You can look at the source of the selection extension to see more +interesting uses, such as parsing a line from beginning to end.
+This extension also offers the following bindable keyboard command:
It works by specifying perl snippets (most useful is a single s///
+operator) that modify $_ as resources:
+ URxvt.selection-autotransform.0: transform + URxvt.selection-autotransform.1: transform + ...+
For example, the following will transform selections of the form
+filename:number, often seen in compiler messages, into vi +$filename
+$word:
+ URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/+
And this example matches the same,but replaces it with vi-commands you can +paste directly into your (vi :) editor:
++ URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/+
Of course, this can be modified to suit your needs and your editor :)
+To expand the example above to typical perl error messages (``XXX at +FILENAME line YYY.''), you need a slightly more elaborate solution:
++ URxvt.selection.pattern-0: ( at .*? line \\d+\\.) + URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/+
The first line tells the selection code to treat the unchanging part of +every error message as a selection pattern, and the second line transforms +the message into vi commands to load the file.
