|
200 | |
|
|
201 | This transforms the terminal into a tabbar with additional terminals, that |
|
|
202 | is, it implements what is commonly refered to as "tabbed terminal". The topmost line |
|
|
203 | displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one |
|
|
204 | button per tab. |
|
|
205 | |
|
|
206 | Clicking a button will activate that tab. Pressing B<Shift-Left> and |
|
|
207 | B<Shift-Right> will switch to the tab left or right of the current one, |
|
|
208 | while B<Shift-Down> creates a new tab. |
|
|
209 | |
|
|
210 | The tabbar itself can be configured similarly to a normal terminal, but |
|

211 | with a resource class of C<URxvt.tabbed>. In addition, it supports the |

259 | =item remote-clipboard |
|
|
260 | |
|
|
261 | Somewhat of a misnomer, this extension adds two menu entries to the |
|
|
262 | selection popup that allows one ti run external commands to store the |
|
|
263 | selection somewhere and fetch it again. |
|
|
264 | |
|
|
265 | We use it to implement a "distributed selection mechanism", which just |
|
|
266 | means that one command uploads the file to a remote server, and another |
|
|
267 | reads it. |
|
|
268 | |
|
|
269 | The commands can be set using the C<URxvt.remote-selection.store> and |
|
|
270 | C<URxvt.remote-selection.fetch> resources. The first should read the |
|
|
271 | selection to store from STDIN (always in UTF-8), the second should provide |
|
|
272 | the selection data on STDOUT (also in UTF-8). |
|
|
273 | |
|
|
274 | The defaults (which are likely useless to you) use rsh and cat: |
|
|
275 | |
|
|
276 | URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection' |
|
|
277 | URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection' |
|
|
278 | |
|
|
279 | =item selection-pastebin |
|
|
280 | |
|
|
281 | This is a little rarely useful extension that Uploads the selection as |
|
|
282 | textfile to a remote site (or does other things). (The implementation is |
|
|
283 | not currently secure for use in a multiuser environment as it writes to |
|
|
284 | F</tmp> directly.). |
|
|
285 | |
|
|
286 | It listens to the C<selection-pastebin:remote-pastebin> keyboard command, |
|
|
287 | i.e. |
|
|
288 | |
|
|
289 | URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
|
|
290 | |
|
|
291 | Pressing this combination runs a command with C<%> replaced by the name of |
|
|
292 | the textfile. This command can be set via a resource: |
|
|
293 | |
|
|
294 | URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/. |
|
|
295 | |
|
|
296 | And the default is likely not useful to anybody but the few people around |
|
|
297 | here :) |
|
|
298 | |
|
|
299 | The name of the textfile is the hex encoded md5 sum of the selection, so |
|
|
300 | the same content should lead to the same filename. |
|
|
301 | |
|
|
302 | After a successful upload the selection will be replaced by the text given |
|
|
303 | in the C<selection-pastebin-url> resource (again, the % is the placeholder |
|
|
304 | for the filename): |
