|
|
166 | |
|
|
167 | A support package that tries to make editing with readline easier. At |
|
|
168 | the moment, it reacts to clicking shift-left mouse button by trying to |
|
|
169 | move the text cursor to this position. It does so by generating as many |
|
|
170 | cursor-left or cursor-right keypresses as required (this only works |
|
|
171 | for programs that correctly support wide characters). |
|
|
172 | |
|
|
173 | To avoid too many false positives, this is only done when: |
|
|
174 | |
|

179 | =item - the text cursor is visible. |

|
180 | |
|
|
181 | =item - the primary screen is currently being displayed. |

144 | =item mark-urls |
225 | =item tabbed |
145 | |
226 | |
|
|
227 | This transforms the terminal into a tabbar with additional terminals, that |
|
|
228 | is, it implements what is commonly referred to as "tabbed terminal". The topmost line |
|
|
229 | displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one |
|
|
230 | button per tab. |
|
|
231 | |
|
|
232 | Clicking a button will activate that tab. Pressing B<Shift-Left> and |
|
|
233 | B<Shift-Right> will switch to the tab left or right of the current one, |
|
|
234 | while B<Shift-Down> creates a new tab. |
|
|
235 | |
|
|
236 | The tabbar itself can be configured similarly to a normal terminal, but |
|
|
237 | with a resource class of C<URxvt.tabbed>. In addition, it supports the |
|
|
238 | following four resources (shown with defaults): |
|
|
239 | |
|
|
240 | URxvt.tabbed.tabbar-fg: <colour-index, default 3> |

|
|
254 | (default, the C<urlLauncher> resource, C<sensible-browser>) will be started |
|
|
255 | with the matched text as first argument. The default configuration is |
|
|
256 | suitable for matching URLs and launching a web browser, like the |
|
|
257 | former "mark-urls" extension. |
|
|
258 | |
|
|
259 | The default pattern to match URLs can be overridden with the |
|
|
260 | C<matcher.pattern.0> resource, and additional patterns can be specified |
|
|
261 | with numbered patterns, in a manner similar to the "selection" extension. |
|
|
262 | The launcher can also be overridden on a per-pattern basis. |

|
|
279 | This (experimental) perl extension implements OnTheSpot editing. It does |
|
|
280 | not work perfectly, and some input methods don't seem to work well with |
|
|
281 | OnTheSpot editing in general, but it seems to work at least for SCIM and |
|
|
282 | kinput2. |
|

289 | =item kuake<hotkey> |
|
|
290 | |
|
|
291 | A very primitive quake-console-like extension. It was inspired by a |
|
|
292 | description of how the programs C<kuake> and C<yakuake> work: Whenever the |
|
|
293 | user presses a global accelerator key (by default C<F10>), the terminal |
|
|
294 | will show or hide itself. Another press of the accelerator key will hide |
|
|
295 | or show it again. |
|
|
296 | |
|
|
297 | Initially, the window will not be shown when using this extension. |
|
|
298 | |
|
|
299 | This is useful if you need a single terminal that is not using any desktop |
|
|
300 | space most of the time but is quickly available at the press of a key. |
|
|
301 | |
|
|
302 | The accelerator key is grabbed regardless of any modifiers, so this |
|
|
303 | extension will actually grab a physical key just for this function. |
|
|
304 | |
|
|
305 | If you want a quake-like animation, tell your window manager to do so |
|
|
306 | (fvwm can do it). |

|
308 | =item overlay-osc |

|

324 | =item remote-clipboard |
|
|
325 | |
|
|
326 | Somewhat of a misnomer, this extension adds two menu entries to the |
|
|
327 | selection popup that allows one to run external commands to store the |
|
|
328 | selection somewhere and fetch it again. |
|
|
329 | |
|
|
330 | We use it to implement a "distributed selection mechanism", which just |
|
|
331 | means that one command uploads the file to a remote server, and another |
|
|
332 | reads it. |
|
|
333 | |
|
|
334 | The commands can be set using the C<URxvt.remote-selection.store> and |
|
|
335 | C<URxvt.remote-selection.fetch> resources. The first should read the |
|
|
336 | selection to store from STDIN (always in UTF-8), the second should provide |
|
|
337 | the selection data on STDOUT (also in UTF-8). |
|
|
338 | |
|
|
339 | The defaults (which are likely useless to you) use rsh and cat: |
|
|
340 | |
|
|
341 | URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection' |
|
|
342 | URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection' |
|
|
343 | |
|
|
344 | =item selection-pastebin |
|
|
345 | |
|
|
346 | This is a little rarely useful extension that Uploads the selection as |
|
|
347 | textfile to a remote site (or does other things). (The implementation is |
|
|
348 | not currently secure for use in a multiuser environment as it writes to |
|
|
349 | F</tmp> directly.). |
|
|
350 | |
|
|
351 | It listens to the C<selection-pastebin:remote-pastebin> keyboard command, |
|
|
352 | i.e. |
|

353 | |
|
|
354 | URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
|

762 | get registered as normal extensions after calling the hooks in C<@TERM_INIT> |
