| 21 | my ($self) = @_; |
|
|
| 22 | |
10 | |
| 23 | my $txt = $self->selection; |
11 | This extension tries to be more intelligent when the user extends |
| 24 | my $h = md5_hex ($txt); |
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>. |
| 25 | |
15 | |
| 26 | my $fn = "/tmp/$h.txt"; |
16 | A double-click usually selects the word under the cursor, further clicks |
|
|
17 | will enlarge the selection. |
| 27 | |
18 | |
| 28 | my $msg = "uploaded $h.txt"; |
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: |
| 29 | |
22 | |
| 30 | if (open my $o, ">" . $fn) { |
23 | URxvt.selection.pattern-0: perl-regex |
| 31 | print $o $txt; |
24 | URxvt.selection.pattern-1: perl-regex |
| 32 | close $o; |
25 | ... |
| 33 | } else { |
|
|
| 34 | $msg = "couldn't write $fn: $!"; |
|
|
| 35 | } |
|
|
| 36 | |
26 | |
| 37 | my $cmd = $pastebin_cmd; |
27 | The index number (0, 1...) must not have any holes, and each regex must |
| 38 | $cmd =~ s/%/$fn/; |
28 | contain at least one pair of capturing parentheses, which will be used for |
| 39 | unless (system ($cmd) == 0) { |
29 | the match. For example, the following adds a regex that matches everything |
| 40 | $msg = "couldn't upload, '$cmd' failed"; |
30 | between two vertical bars: |
| 41 | } |
|
|
| 42 | |
31 | |
| 43 | $self->selection ($pastebin_url . "$h.txt"); |
32 | URxvt.selection.pattern-0: \\|([^|]+)\\| |
| 44 | |
33 | |
| 45 | my $ov = $timers->{ov} = $self->overlay (-1, 0, length ($msg), 1, urxvt::OVERLAY_RSTYLE, 0); |
34 | Another example: Programs I use often output "absolute path: " at the |
| 46 | $ov->set (0, 0, $msg); |
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): |
| 47 | |
38 | |
| 48 | $timers->{t1} = |
39 | URxvt.selection.pattern-0: ^(/[^:]+):\ |
| 49 | urxvt::timer |
|
|
| 50 | ->new |
|
|
| 51 | ->start ((int urxvt::NOW) + 5) # make sure we update "on" the second |
|
|
| 52 | ->interval (1) |
|
|
| 53 | ->cb (sub { delete $timers->{ov}; delete $timers->{t1}; }); |
|
|
| 54 | } |
