|
|
10 | |
|
|
11 | This extension tries to be more intelligent when the user extends |
|
|
12 | selections (double-click and further clicks). Right now, it tries to |
|
|
13 | select words, urls and complete shell-quoted arguments, which is very |
|
|
14 | convenient, too, if your F<ls> supports C<--quoting-style=shell>. |
|
|
15 | |
|
|
16 | A double-click usually selects the word under the cursor, further clicks |
|
|
17 | will enlarge the selection. |
|
|
18 | |
|
|
19 | The selection works by trying to match a number of regexes and displaying |
|
|
20 | them in increasing order of length. You can add your own regexes by |
|
|
21 | specifying resources of the form: |
|
|
22 | |
|
|
23 | URxvt.selection.pattern-0: perl-regex |
|
|
24 | URxvt.selection.pattern-1: perl-regex |
|
|
25 | ... |
|
|
26 | |
|
|
27 | The index number (0, 1...) must not have any holes, and each regex must |
|
|
28 | contain at least one pair of capturing parentheses, which will be used for |
|
|
29 | the match. For example, the following adds a regex that matches everything |
|
|
30 | between two vertical bars: |
|
|
31 | |
|
|
32 | URxvt.selection.pattern-0: \\|([^|]+)\\| |
|
|
33 | |
|
|
34 | Another example: Programs I use often output "absolute path: " at the |
|
|
35 | beginning of a line when they process multiple files. The following |
|
|
36 | pattern matches the filename (note, there is a single space at the very |
|
|
37 | end): |
|
|
38 | |
|
|
39 | URxvt.selection.pattern-0: ^(/[^:]+):\ |
|
|
40 | |
|
|
41 | You can look at the source of the selection extension to see more |
|
|
42 | interesting uses, such as parsing a line from beginning to end. |
|
|
43 | |
|
|
44 | This extension also offers the following actions: |
|
|
45 | |
|
|
46 | =over 4 |
|
|
47 | |
|
|
48 | =item rot13 |
|
|
49 | |
|
|
50 | Rot-13 the selection when activated. |
|
|
51 | |
|
|
52 | Example: |
|
|
53 | |
|
|
54 | URxvt.keysym.C-M-r: selection:rot13 |
|
|
55 | |
|
|
