162 | |
223 | |
|
|
224 | This transforms the terminal into a tabbar with additional terminals, that |
|
|
225 | is, it implements what is commonly referred to as "tabbed terminal". The topmost line |
|
|
226 | displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one |
|
|
227 | button per tab. |
|
|
228 | |
|
|
229 | Clicking a button will activate that tab. Pressing B<Shift-Left> and |
|
|
230 | B<Shift-Right> will switch to the tab left or right of the current one, |
|
|
231 | while B<Shift-Down> creates a new tab. |
|
|
232 | |
|
|
233 | The tabbar itself can be configured similarly to a normal terminal, but |
|
|
234 | with a resource class of C<URxvt.tabbed>. In addition, it supports the |

282 | =item kuake<hotkey> |
|
|
283 | |
|
|
284 | A very primitive quake-console-like extension. It was inspired by a |
|
|
285 | description of how the programs C<kuake> and C<yakuake> work: Whenever the |
|
|
286 | user presses a global accelerator key (by default C<F10>), the terminal |
|
|
287 | will show or hide itself. Another press of the accelerator key will hide |
|
|
288 | or show it again. |
|
|
289 | |
|
|
290 | Initially, the window will not be shown when using this extension. |
|
|
291 | |
|
|
292 | This is useful if you need a single terminal thats not using any desktop |
|
|
293 | space most of the time but is quickly available at the press of a key. |
|
|
294 | |
|
|
295 | The accelerator key is grabbed regardless of any modifiers, so this |
|
|
296 | extension will actually grab a physical key just for this function. |
|

|
|
321 | |
|
|
322 | Somewhat of a misnomer, this extension adds two menu entries to the |
|
|
323 | selection popup that allows one ti run external commands to store the |
|
|
324 | selection somewhere and fetch it again. |
|
|
325 | |
|
|
326 | We use it to implement a "distributed selection mechanism", which just |
|
|
327 | means that one command uploads the file to a remote server, and another |
|
|
328 | reads it. |
|
|
329 | |
|
|
330 | The commands can be set using the C<URxvt.remote-selection.store> and |
|
|
331 | C<URxvt.remote-selection.fetch> resources. The first should read the |
|
|
332 | selection to store from STDIN (always in UTF-8), the second should provide |
|
|
333 | the selection data on STDOUT (also in UTF-8). |
|
|
334 | |
|
|
335 | The defaults (which are likely useless to you) use rsh and cat: |
|

|

|
|
341 | |
|
|
342 | This is a little rarely useful extension that Uploads the selection as |

|
|
344 | not currently secure for use in a multiuser environment as it writes to |

|

346 | |

352 | Pressing this combination runs a command with C<%> replaced by the name of |
|
|
353 | the textfile. This command can be set via a resource: |

354 | |
|

355 | URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/. |

357 | And the default is likely not useful to anybody but the few people around |
|

|
|
360 | The name of the textfile is the hex encoded md5 sum of the selection, so |
|
|
361 | the same content should lead to the same filename. |
|
|
362 | |
|
|
363 | After a successful upload the selection will be replaced by the text given |
|
|
364 | in the C<selection-pastebin-url> resource (again, the % is the placeholder |
|
|
365 | for the filename): |

|
|
370 | the double C</> characters as comment start. Use C<\057\057> instead, |
