|
199 | |
|
|
200 | This is a little rarely useful extension that Uploads the selection as |
|
|
201 | textfile to a remote site (or does other things). (The implementation is |
|
|
202 | not currently secure for use in a multiuser environment as it writes to |
|
|
203 | F</tmp> directly.). |
|
|
204 | |
|
|
205 | It listens to the C<selection-pastebin:remote-pastebin> keyboard command, |
|
|
206 | i.e. |
|
|
207 | |
|
|
208 | URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
|
|
209 | |
|
|
210 | Pressing this combination runs a command with C<%> replaced by the name of |
|
|
211 | the textfile. This command can be set via a resource: |
|
|
212 | |
|
|
213 | URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/. |
|
|
214 | |
|
|
215 | And the default is likely not useful to anybody but the few people around |
|
|
216 | here :) |
|
|
217 | |
|
|
218 | The name of the textfile is the hex encoded md5 sum of the selection, so |
|
|
219 | the same content should lead to the same filename. |
|
|
220 | |
|
|
221 | After a successful upload the selection will be replaced by the text given |
