|
|

|
|
10 | =head1 DESCRIPTION |
|
|
11 | |
|
|
12 | This is a little rarely useful extension that uploads the selection as |
|
|
13 | textfile to a remote site (or does other things). (The implementation is |
|
|
14 | not currently secure for use in a multiuser environment as it writes to |
|
|
15 | F</tmp> directly.). |
|
|
16 | |
|
|
17 | It listens to the C<selection-pastebin:remote-pastebin> keyboard command, |
|
|
18 | i.e. |
|
|
19 | |
|
|
20 | URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
|
|
21 | |
|
|
22 | Pressing this combination runs a command with C<%> replaced by the name of |
|
|
23 | the textfile. This command can be set via a resource: |
|
|
24 | |
|
|
25 | URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/. |
|
|
26 | |
|
|
27 | And the default is likely not useful to anybody but the few people around |
|
|
28 | here :) |
|
|
29 | |
|
|
30 | The name of the textfile is the hex encoded md5 sum of the selection, so |
|
|
31 | the same content should lead to the same filename. |
|
|
32 | |
|
|
33 | After a successful upload the selection will be replaced by the text given |
|
|
34 | in the C<selection-pastebin-url> resource (again, the % is the placeholder |
|
|
35 | for the filename): |
|
|
36 | |
|
|
37 | URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/% |
|
|
38 | |
|
|
39 | I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret |
|
|
40 | the double C</> characters as comment start. Use C<\057\057> instead, |
|
|
41 | which works regardless of whether xrdb is used to parse the resource file |
|
|
42 | or not. |
