=head1 DESCRIPTION |
| 15 |
|
| 16 |
This is a little rarely useful extension that uploads the selection as |
| 17 |
textfile to a remote site (or does other things). (The implementation is |
| 18 |
not currently secure for use in a multiuser environment as it writes to |
| 19 |
F</tmp> directly.). |
| 20 |
|
| 21 |
It listens to the C<selection-pastebin:remote-pastebin> action, which, |
| 22 |
when activated, runs a command with C<%> replaced by the name of the |
| 23 |
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. |
