53 | |
|
|
54 | A double-click usually selects the word under the cursor, further clicks |
|
|
55 | will enlarge the selection. |
|
|
56 | |
|
|
57 | The selection works by trying to match a number of regexes and displaying |
|
|
58 | them in increasing order of length. You can add your own regexes by |
|
|
59 | specifying resources of the form: |
|
|
60 | |
|
|
61 | URxvt.selection.pattern-0: perl-regex |
|
|
62 | URxvt.selection.pattern-1: perl-regex |
|
|
63 | ... |
|
|
64 | |
|
|
65 | The index number (0, 1...) must not have any holes, and each regex must |
|
|
66 | contain at least one pair of capturing parentheses, which will be used for |
|
|
67 | the match. For example, the following adds a regex that matches everything |
|
|
68 | between two vertical bars: |
|
|
69 | |
|
|
70 | URxvt.selection.pattern-0: \\|([^|]+)\\| |
|
|
71 | |
|
|
72 | Another example: Programs I use often output "absolute path: " at the |
|
|
73 | beginning of a line when they process multiple files. The following |
|
|
74 | pattern matches the filename (note, there is a single space at the very |
|
|
75 | end): |
|
|
76 | |
|
|
77 | URxvt.selection.pattern-0: ^(/[^:]+):\ |

162 | =item readline (enabled by default) |
|
|
163 | |
|
|
164 | A support package that tries to make editing with readline easier. At |
|
|
165 | the moment, it reacts to clicking shift-left mouse button by trying to |
|
|
166 | move the text cursor to this position. It does so by generating as many |
|
|
167 | cursor-left or cursor-right keypresses as required (the this only works |
|
|
168 | for programs that correctly support wide characters). |
|
|
169 | |
|
|
170 | To avoid too many false positives, this is only done when: |
|
|
171 | |
|
|
172 | =over 4 |
|
|
173 | |
|
|
174 | =item - the tty is in ICANON state. |
|
|
175 | |
|
|
176 | =item - the text cursor is visible. |
|
|
177 | |
|
|
178 | =item - the primary screen is currently being displayed. |
|
|
179 | |
|
|
180 | =item - the mouse is on the same (multi-row-) line as the text cursor. |
|
|
181 | |
|
|
182 | =back |
|
|
183 | |
|
|
184 | The normal selection mechanism isn't disabled, so quick successive clicks |
|
|
185 | might interfere with selection creation in harmless ways. |
|
|
186 | |
|
|
187 | =item selection-autotransform |
|
|
188 | |
|
|
189 | This selection allows you to do automatic transforms on a selection |
|
|
190 | whenever a selection is made. |
|
|
191 | |
|
|
192 | It works by specifying perl snippets (most useful is a single C<s///> |
|
|
193 | operator) that modify C<$_> as resources: |
|
|
194 | |
|
|
195 | URxvt.selection-autotransform.0: transform |
|
|
196 | URxvt.selection-autotransform.1: transform |
|
|
197 | ... |
|
|
198 | |
|
|
199 | For example, the following will transform selections of the form |
|
|
200 | C<filename:number>, often seen in compiler messages, into C<vi +$filename |
|
|
201 | $word>: |
|
|
202 | |
|
|
203 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/ |
|
|
204 | |
|
|
205 | And this example matches the same,but replaces it with vi-commands you can |
|
|
206 | paste directly into your (vi :) editor: |
|
|
207 | |
|
|
208 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/ |
|
|
209 | |
|
|
210 | Of course, this can be modified to suit your needs and your editor :) |
|
|
211 | |
|
|
212 | To expand the example above to typical perl error messages ("XXX at |
|
|
213 | FILENAME line YYY."), you need a slightly more elaborate solution: |
|
|
214 | |
|
|
215 | URxvt.selection.pattern-0: ( at .*? line \\d+[,.]) |
|
|
216 | URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/ |
|
|
217 | |
|
|
218 | The first line tells the selection code to treat the unchanging part of |
|
|
219 | every error message as a selection pattern, and the second line transforms |
|
|
220 | the message into vi commands to load the file. |
|
|
221 | |
|
|
222 | =item tabbed |
|
|
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 |
|
|
235 | following four resources (shown with defaults): |
|
|
236 | |
|
|
237 | URxvt.tabbed.tabbar-fg: <colour-index, default 3> |
|

|
|
265 | |
|
|
266 | A very primitive quake-console-like extension. It was inspired by a |
|
|
267 | description of how the programs C<kuake> and C<yakuake> work: Whenever the |
|
|
268 | user presses a global accelerator key (by default C<F10>), the terminal |
|
|
269 | will show or hide itself. Another press of the accelerator key will hide |
|
|
270 | or show it again. |
|
|
271 | |
|
|
272 | Initially, the window will not be shown when using this extension. |
|
|
273 | |
|
|
274 | This is useful if you need a single terminal thats not using any desktop |
|
|
275 | space most of the time but is quickly available at the press of a key. |
|
|
276 | |
|
|
277 | The accelerator key is grabbed regardless of any modifiers, so this |
|
|
278 | extension will actually grab a physical key just for this function. |

302 | =item remote-clipboard |
|
|
303 | |
|
|
304 | Somewhat of a misnomer, this extension adds two menu entries to the |
|
|
305 | selection popup that allows one ti run external commands to store the |
|
|
306 | selection somewhere and fetch it again. |
|
|
307 | |
|
|
308 | We use it to implement a "distributed selection mechanism", which just |
|
|
309 | means that one command uploads the file to a remote server, and another |
|
|
310 | reads it. |
|
|
311 | |
|
|
312 | The commands can be set using the C<URxvt.remote-selection.store> and |
|
|
313 | C<URxvt.remote-selection.fetch> resources. The first should read the |
|
|
314 | selection to store from STDIN (always in UTF-8), the second should provide |
|
|
315 | the selection data on STDOUT (also in UTF-8). |
|
|
316 | |
|
|
317 | The defaults (which are likely useless to you) use rsh and cat: |
|
|
318 | |
|
|
319 | URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection' |
|
|
320 | URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection' |
|
|
321 | |
|
|
322 | =item selection-pastebin |
|
|
323 | |
|
|
324 | This is a little rarely useful extension that Uploads the selection as |
|
|
325 | textfile to a remote site (or does other things). (The implementation is |
|
|
326 | not currently secure for use in a multiuser environment as it writes to |
|
|
327 | F</tmp> directly.). |
|
|
328 | |
|
|
329 | It listens to the C<selection-pastebin:remote-pastebin> keyboard command, |
|
|
330 | i.e. |
|
|
331 | |
|
|
332 | URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
|
|
333 | |
|
|
334 | Pressing this combination runs a command with C<%> replaced by the name of |
|
|
335 | the textfile. This command can be set via a resource: |
|
|
336 | |
|
|
337 | URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/. |
|
|
338 | |
|
|
339 | And the default is likely not useful to anybody but the few people around |
|
|
340 | here :) |
|
|
341 | |
|
|
342 | The name of the textfile is the hex encoded md5 sum of the selection, so |
|
|
343 | the same content should lead to the same filename. |
|
|
344 | |
|
|
345 | After a successful upload the selection will be replaced by the text given |
|
|
346 | in the C<selection-pastebin-url> resource (again, the % is the placeholder |
|
|
347 | for the filename): |

695 | |
|

696 | =item $urxvt::LIBDIR |
|
|
697 | |
|
|
698 | The rxvt-unicode library directory, where, among other things, the perl |
|
|
699 | modules and scripts are stored. |
|
|
700 | |
|
|
701 | =item $urxvt::RESCLASS, $urxvt::RESCLASS |
|
|
702 | |
|
|
703 | The resource class and name rxvt-unicode uses to look up X resources. |
|
|
704 | |
|
|
705 | =item $urxvt::RXVTNAME |
|
|
706 | |
|
|
707 | The basename of the installed binaries, usually C<urxvt>. |
|
|
708 | |
|
|
709 | =item $urxvt::TERM |
|
|
710 | |
|
|
711 | The current terminal. This variable stores the current C<urxvt::term> |
|
|
712 | object, whenever a callback/hook is executing. |
|
|
713 | |
|
|
714 | =item @urxvt::TERM_INIT |
|
|
715 | |
|
|
716 | All code references in this array will be called as methods of the next newly |
|
|
717 | created C<urxvt::term> object (during the C<on_init> phase). The array |
|
|
718 | gets cleared before the code references that were in it are being executed, |
|
|
719 | so references can push themselves onto it again if they so desire. |
|
|
720 | |
|
|
721 | This complements to the perl-eval command line option, but gets executed |
|
|
722 | first. |
|
|
723 | |
|
|
724 | =item @urxvt::TERM_EXT |
|
|
725 | |
|
|
726 | Works similar to C<@TERM_INIT>, but contains perl package/class names, which |
|
|
727 | get registered as normal extensions after calling the hooks in C<@TERM_INIT> |
|
|
728 | but before other extensions. Gets cleared just like C<@TERM_INIT>. |

735 | |
|
|
736 | =item urxvt::fatal $errormessage |
|
|
737 | |
|
|
738 | Fatally aborts execution with the given error message. Avoid at all |
|
|
739 | costs! The only time this is acceptable is when the terminal process |
|
|
740 | starts up. |
|
|
741 | |
|
|
742 | =item urxvt::warn $string |
|
|
743 | |
|
|
744 | Calls C<rxvt_warn> with the given string which should not include a |
|
|
745 | newline. The module also overwrites the C<warn> builtin with a function |
|
|
746 | that calls this function. |
|
|
747 | |
|
|
748 | Using this function has the advantage that its output ends up in the |
|
|
749 | correct place, e.g. on stderr of the connecting urxvtc client. |
|

|
|
752 | |
|
|
753 | =item @terms = urxvt::termlist |
|
|
754 | |
|
|
755 | Returns all urxvt::term objects that exist in this process, regardless of |
|
|
756 | whether they are started, being destroyed etc., so be careful. Only term |
|
|
757 | objects that have perl extensions attached will be returned (because there |

|
|
791 | |
|

792 | Rendition bitsets contain information about colour, font, font styles and |
|
|
793 | similar information for each screen cell. |
|
|
794 | |
|
|
795 | The following "macros" deal with changes in rendition sets. You should |
|
|
796 | never just create a bitset, you should always modify an existing one, |
|
|
797 | as they contain important information required for correct operation of |
|
|
798 | rxvt-unicode. |
