54 | arguments, which is very convenient, too, if your F<ls> supports |
|
|
55 | C<--quoting-style=shell>. |
48 | |
56 | |
49 | It also offers the following bindable event: |
57 | A double-click usually selects the word under the cursor, further clicks |
|
|
58 | will enlarge the selection. |
|
|
59 | |
|
|
60 | The selection works by trying to match a number of regexes and displaying |
|
|
61 | them in increasing order of length. You can add your own regexes by |
|
|
62 | specifying resources of the form: |
|
|
63 | |
|
|
64 | URxvt.selection.pattern-0: perl-regex |
|
|
65 | URxvt.selection.pattern-1: perl-regex |
|
|
66 | ... |
|
|
67 | |
|
|
68 | The index number (0, 1...) must not have any holes, and each regex must |
|
|
69 | contain at least one pair of capturing parentheses, which will be used for |
|
|
70 | the match. For example, the following adds a regex that matches everything |
|
|
71 | between two vertical bars: |
|
|
72 | |
|
|
73 | URxvt.selection.pattern-0: \\|([^|]+)\\| |
|
|
74 | |
|
|
75 | Another example: Programs I use often output "absolute path: " at the |
|
|
76 | beginning of a line when they process multiple files. The following |
|
|
77 | pattern matches the filename (note, there is a single space at the very |
|
|
78 | end): |
|
|
79 | |
|
|
80 | URxvt.selection.pattern-0: ^(/[^:]+):\ |
|
|
81 | |

|
|
83 | interesting uses, such as parsing a line from beginning to end. |

151 | Inputting characters appends them to the regex and continues incremental |
|
|
152 | search. C<BackSpace> removes a character from the regex, C<Up> and C<Down> |
|
|
153 | search upwards/downwards in the scrollback buffer, C<End> jumps to the |
|
|
154 | bottom. C<Escape> leaves search mode and returns to the point where search |
|
|
155 | was started, while C<Enter> or C<Return> stay at the current position and |
|
|
156 | additionally stores the first match in the current line into the primary |
|
|
157 | selection if the C<Shift> modifier is active. |

81 | Displays a digital clock using the built-in overlay. |
159 | The regex defaults to "(?i)", resulting in a case-insensitive search. To |
|
|
160 | get a case-sensitive search you can delete this prefix using C<BackSpace> |
|
|
161 | or simply use an uppercase character which removes the "(?i)" prefix. |
82 | |

163 | See L<perlre> for more info about perl regular expression syntax. |
84 | |
164 | |
|
|
165 | =item readline (enabled by default) |
|
|
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 | |
|
|
175 | =over 4 |
|
|
176 | |
|
|
177 | =item - the tty is in ICANON state. |
|
|
178 | |
|
|
179 | =item - the text cursor is visible. |
|
|
180 | |
|
|
181 | =item - the primary screen is currently being displayed. |
|
|
182 | |
|
|
183 | =item - the mouse is on the same (multi-row-) line as the text cursor. |
|
|
184 | |
|
|
185 | =back |
|
|
186 | |
|
|
187 | The normal selection mechanism isn't disabled, so quick successive clicks |
|
|
188 | might interfere with selection creation in harmless ways. |
|
|
189 | |
|
|
190 | =item selection-autotransform |
|
|
191 | |
|
|
192 | This selection allows you to do automatic transforms on a selection |
|
|
193 | whenever a selection is made. |
|
|
194 | |
|
|
195 | It works by specifying perl snippets (most useful is a single C<s///> |
|
|
196 | operator) that modify C<$_> as resources: |
|
|
197 | |
|
|
198 | URxvt.selection-autotransform.0: transform |
|
|
199 | URxvt.selection-autotransform.1: transform |
|
|
200 | ... |
|
|
201 | |
|
|
202 | For example, the following will transform selections of the form |
|
|
203 | C<filename:number>, often seen in compiler messages, into C<vi +$filename |
|
|
204 | $word>: |
|
|
205 | |
|
|
206 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/ |
|
|
207 | |
|
|
208 | And this example matches the same,but replaces it with vi-commands you can |
|
|
209 | paste directly into your (vi :) editor: |
|
|
210 | |
|
|
211 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/ |
|
|
212 | |
|
|
213 | Of course, this can be modified to suit your needs and your editor :) |
|
|
214 | |
|
|
215 | To expand the example above to typical perl error messages ("XXX at |
|
|
216 | FILENAME line YYY."), you need a slightly more elaborate solution: |
|
|
217 | |
|
|
218 | URxvt.selection.pattern-0: ( at .*? line \\d+[,.]) |
|
|
219 | URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/ |
|
|
220 | |
|
|
221 | The first line tells the selection code to treat the unchanging part of |
|
|
222 | every error message as a selection pattern, and the second line transforms |
|
|
223 | the message into vi commands to load the file. |
|
|
224 | |
|
|
225 | =item tabbed |
|
|
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> |
|
|
241 | URxvt.tabbed.tabbar-bg: <colour-index, default 0> |
|
|
242 | URxvt.tabbed.tab-fg: <colour-index, default 0> |
|
|
243 | URxvt.tabbed.tab-bg: <colour-index, default 1> |
|
|
244 | |
|
|
245 | See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid |
|
|
246 | indices. |

248 | =item matcher |

|
249 | |
85 | Uses per-line display filtering (C<on_line_update>) to underline urls. |
250 | Uses per-line display filtering (C<on_line_update>) to underline text |
|
|
251 | matching a certain pattern and make it clickable. When clicked with the |
|
|
252 | mouse button specified in the C<matcher.button> resource (default 2, or |
|
|
253 | middle), the program specified in the C<matcher.launcher> resource |
|
|
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. |
|
|
263 | |
|
|
264 | It is possible to activate the most recently seen match or a list of matches |
|
|
265 | from the keyboard. Simply bind a keysym to "perl:matcher:last" or |
|
|
266 | "perl:matcher:list" as seen in the example below. |

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

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

310 | =item overlay-osc |
|
|

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

|
353 | It listens to the C<selection-pastebin:remote-pastebin> keyboard command, |
|
|
354 | i.e. |
|
|
355 | |
|
|
356 | URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
|
|
357 | |
|
|
358 | Pressing this combination runs a command with C<%> replaced by the name of |
|
|
359 | the textfile. This command can be set via a resource: |
|
|
360 | |
|
|
361 | URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/. |
|
|
362 | |
|
|
363 | And the default is likely not useful to anybody but the few people around |
|
|
364 | here :) |
|
|
365 | |
|
|
366 | The name of the textfile is the hex encoded md5 sum of the selection, so |
|
|
367 | the same content should lead to the same filename. |
|
|
368 | |
|
|
369 | After a successful upload the selection will be replaced by the text given |
|
|
370 | in the C<selection-pastebin-url> resource (again, the % is the placeholder |
|
|
371 | for the filename): |
|
|
372 | |
|
|
373 | URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/% |
|
|
374 | |
|
|
375 | I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret |
|
|
376 | the double C</> characters as comment start. Use C<\057\057> instead, |
|
|
377 | which works regardless of whether xrdb is used to parse the resource file |
|
|
378 | or not. |
|

380 | =item macosx-clipboard and macosx-clipboard-native |
|
|
381 | |
|
|
382 | These two modules implement an extended clipboard for Mac OS X. They are |
|
|
383 | used like this: |
|
|
384 | |
|
|
385 | URxvt.perl-ext-common: default,macosx-clipboard |
|
|
386 | URxvt.keysym.M-c: perl:macosx-clipboard:copy |
|
|
387 | URxvt.keysym.M-v: perl:macosx-clipboard:paste |
|
|
388 | |
|
|
389 | The difference between them is that the native variant requires a |
|
|
390 | perl from apple's devkit or so, and C<macosx-clipboard> requires the |
|
|
391 | C<Mac::Pasteboard> module, works with other perls, has fewer bugs, is |
|
|
392 | simpler etc. etc. |

356 | |
|
|
357 | =item $term = new urxvt [arg...] |
|
|
358 | |
|
|
359 | Creates a new terminal, very similar as if you had started it with |
|
|
360 | C<system $binfile, arg...>. Croaks (and probably outputs an error message) |
|
|
361 | if the new instance couldn't be created. Returns C<undef> if the new |
|
|
362 | instance didn't initialise perl, and the terminal object otherwise. The |
|

363 | C<init> and C<start> hooks will be called during the call. |
|
|
364 | |
|
|
365 | =item urxvt::fatal $errormessage |
|
|
366 | |
|
|
367 | Fatally aborts execution with the given error message. Avoid at all |

|
|
369 | starts up. |
