157 Everytime a terminal object gets created, extension scripts specified via
158 the \f(CW\*(C`perl\*(C'\fR resource are loaded and associated with it.
159 .PP
160 Scripts are compiled in a 'use strict' and 'use utf8' environment, and
161 thus must be encoded as \s-1UTF\-8\s0.
162 .PP

164 scripts will be shared (but not enabled) for all terminals.

167 This section describes the extensions delivered with this release. You can
168 find them in \fI@@RXVT_LIBDIR@@/urxvt/perl/\fR.

175 .IP "selection (enabled by default)" 4
176 .IX Item "selection (enabled by default)"
177 (More) intelligent selection. This extension tries to be more intelligent
178 when the user extends selections (double\-click and further clicks). Right
179 now, it tries to select words, urls and complete shell-quoted
180 arguments, which is very convenient, too, if your \fIls\fR supports
181 \&\f(CW\*(C`\-\-quoting\-style=shell\*(C'\fR.
182 .Sp
183 A double-click usually selects the word under the cursor, further clicks
184 will enlarge the selection.
185 .Sp
186 The selection works by trying to match a number of regexes and displaying
187 them in increasing order of length. You can add your own regexes by
188 specifying resources of the form:
189 .Sp
190 .Vb 3
191 \& URxvt.selection.pattern-0: perl-regex
192 \& URxvt.selection.pattern-1: perl-regex
193 \& ...
194 .Ve
195 .Sp
196 The index number (0, 1...) must not have any holes, and each regex must
197 contain at least one pair of capturing parentheses, which will be used for
198 the match. For example, the followign adds a regex that matches everything
199 between two vertical bars:
200 .Sp
201 .Vb 1
202 \& URxvt.selection.pattern-0: \e\e|([^|]+)\e\e|
203 .Ve
204 .Sp
205 You can look at the source of the selection extension to see more
206 interesting uses, such as parsing a line from beginning to end.
207 .Sp
208 This extension also offers following bindable keyboard commands:
209 .RS 4
210 .IP "rot13" 4
211 .IX Item "rot13"
212 Rot\-13 the selection when activated. Used via keyboard trigger:
213 .Sp
214 .Vb 1
215 \& URxvt.keysym.C-M-r: perl:selection:rot13
216 .Ve
217 .IP "remote-pastebin" 4
218 .IX Item "remote-pastebin"
219 Upload the selection as textfile to a remote site.
220 .Sp
221 .Vb 1
222 \& URxvt.keysym.C-M-e: perl:selection:remote-pastebin
223 .Ve
224 .Sp
225 To set the command to upload the file set this resource:
226 .Sp
227 .Vb 1
228 \& URxvt.selection-pastebin-cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
229 .Ve
230 .Sp
231 The % is the placeholder for the textfile. The name of the textfile is the hex encoded
232 md5 sum of the selection.
233 After an successful upload the selection will be replaced by the following url
234 (the % is the placeholder for the filename):
235 .Sp
236 .Vb 1

242 .IP "option-popup (enabled by default)" 4
243 .IX Item "option-popup (enabled by default)"
244 Binds a popup menu to Ctrl\-Button2 that lets you toggle (some) options at
245 runtime.
246 .IP "selection-popup (enabled by default)" 4
247 .IX Item "selection-popup (enabled by default)"
248 Binds a popup menu to Ctrl\-Button3 that lets you convert the selection
249 text into various other formats/action (such as uri unescaping, perl
250 evalution, web-browser starting etc.), depending on content.
251 .IP "searchable\-scrollback<hotkey> (enabled by default)" 4
252 .IX Item "searchable-scrollback<hotkey> (enabled by default)"
253 Adds regex search functionality to the scrollback buffer, triggered
254 by a hotkey (default: \f(CW\*(C`M\-s\*(C'\fR). While in search mode, normal terminal
255 input/output is suspended and a regex is displayed at the bottom of the
256 screen.
257 .Sp
258 Inputting characters appends them to the regex and continues incremental
259 search. \f(CW\*(C`BackSpace\*(C'\fR removes a character from the regex, \f(CW\*(C`Up\*(C'\fR and \f(CW\*(C`Down\*(C'\fR
260 search upwards/downwards in the scrollback buffer, \f(CW\*(C`End\*(C'\fR jumps to the
261 bottom. \f(CW\*(C`Escape\*(C'\fR leaves search mode and returns to the point where search
262 was started, while \f(CW\*(C`Enter\*(C'\fR or \f(CW\*(C`Return\*(C'\fR stay at the current position and
263 additionally stores the first match in the current line into the primary
264 selection.
265 .IP "selection-autotransform" 4
266 .IX Item "selection-autotransform"
267 This selection allows you to do automatic transforms on a selection
268 whenever a selection is made.
269 .Sp
270 It works by specifying perl snippets (most useful is a single \f(CW\*(C`s///\*(C'\fR
271 operator) that modify \f(CW$_\fR as resources:
272 .Sp
273 .Vb 3
274 \& URxvt.selection-autotransform.0: transform
275 \& URxvt.selection-autotransform.1: transform
276 \& ...
277 .Ve
278 .Sp
279 For example, the following will transform selections of the form
280 \&\f(CW\*(C`filename:number\*(C'\fR, often seen in compiler messages, into \f(CW\*(C`vi +$filename
281 $word\*(C'\fR:
282 .Sp
283 .Vb 1
284 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\e\ed+):?$/vi +$2 \e\eQ$1\e\eE\e\ex0d/
285 .Ve
286 .Sp
287 And this example matches the same,but replaces it with vi-commands you can
288 paste directly into your (vi :) editor:
289 .Sp
290 .Vb 1
291 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\e\ed+):?$/\e\ex1b:e \e\eQ$1\e\eE\e\ex0d:$2\e\ex0d/
292 .Ve
293 .Sp
294 Of course, this can be modified to suit your needs and your editor :)
295 .Sp
296 To expand the example above to typical perl error messages (\*(L"\s-1XXX\s0 at
297 \&\s-1FILENAME\s0 line \s-1YYY\s0.\*(R"), you need a slightly more elaborate solution:
298 .Sp
299 .Vb 2
300 \& URxvt.selection.pattern-0: ( at .*? line \e\ed+\e\e.)
301 \& URxvt.selection-autotransform.0: s/^ at (.*?) line (\e\ed+)\e\e.$/\ex1b:e \e\eQ$1\eE\e\ex0d:$2\e\ex0d/
302 .Ve
303 .Sp
304 The first line tells the selection code to treat the unchanging part of
305 every error message as a selection pattern, and the second line transforms
306 the message into vi commands to load the file.
307 .IP "mark-urls" 4
308 .IX Item "mark-urls"
309 Uses per-line display filtering (\f(CW\*(C`on_line_update\*(C'\fR) to underline urls and
310 make them clickable. When middle\-clicked, the program specified in the
311 resource \f(CW\*(C`urlLauncher\*(C'\fR (default \f(CW\*(C`x\-www\-browser\*(C'\fR) will be started with
312 the \s-1URL\s0 as first argument.
313 .IP "block-graphics-to-ascii" 4
314 .IX Item "block-graphics-to-ascii"
315 A not very useful example of filtering all text output to the terminal,
316 by replacing all line-drawing characters (U+2500 .. U+259F) by a
317 similar-looking ascii character.
318 .IP "digital-clock" 4
319 .IX Item "digital-clock"
320 Displays a digital clock using the built-in overlay.
321 .IP "example-refresh-hooks" 4
322 .IX Item "example-refresh-hooks"
323 Displays a very simple digital clock in the upper right corner of the
324 window. Illustrates overwriting the refresh callbacks to create your own
325 overlays or changes.
326 .SH "API DOCUMENTATION"
327 .IX Header "API DOCUMENTATION"
328 .Sh "General \s-1API\s0 Considerations"
329 .IX Subsection "General API Considerations"
330 All objects (such as terminals, time watchers etc.) are typical
331 reference-to-hash objects. The hash can be used to store anything you
332 like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or
333 \&\f(CW\*(C`_hook\*(C'\fR) are reserved for internal uses and \fB\s-1MUST\s0 \s-1NOT\s0\fR be accessed or
334 modified).
335 .PP
336 When objects are destroyed on the \*(C+ side, the perl object hashes are
337 emptied, so its best to store related objects such as time watchers and
338 the like inside the terminal object so they get destroyed as soon as the
339 terminal is destroyed.
340 .PP
341 Argument names also often indicate the type of a parameter. Here are some
342 hints on what they mean:
343 .IP "$text" 4
344 .IX Item "$text"
345 Rxvt-unicodes special way of encoding text, where one \*(L"unicode\*(R" character
346 always represents one screen cell. See ROW_t for a discussion of this format.
347 .IP "$string" 4
348 .IX Item "$string"
349 A perl text string, with an emphasis on \fItext\fR. It can store all unicode
350 characters and is to be distinguished with text encoded in a specific
351 encoding (often locale\-specific) and binary data.
352 .IP "$octets" 4
353 .IX Item "$octets"
354 Either binary data or \- more common \- a text string encoded in a
355 locale-specific way.
356 .Sh "Extension Objects"
357 .IX Subsection "Extension Objects"
358 Very perl extension is a perl class. A separate perl object is created
359 for each terminal and each extension and passed as the first parameter to
360 hooks. So extensions can use their \f(CW$self\fR object without having to think
361 about other extensions, with the exception of methods and members that
362 begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for internal
363 use.
364 .PP
365 Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the
366 \&\f(CW\*(C`urxvt::term\*(C'\fR class on this object.
367 .PP
368 It has the following methods and data members:
369 .ie n .IP "$urxvt_term = $self\->{term}" 4
370 .el .IP "$urxvt_term = \f(CW$self\fR\->{term}" 4
371 .IX Item "$urxvt_term = $self->{term}"
372 Returns the \f(CW\*(C`urxvt::term\*(C'\fR object associated with this instance of the
373 extension. This member \fImust not\fR be changed in any way.
374 .ie n .IP "$self\->enable ($hook_name => $cb\fR, [$hook_name => \f(CW$cb..])" 4
375 .el .IP "$self\->enable ($hook_name => \f(CW$cb\fR, [$hook_name => \f(CW$cb\fR..])" 4
376 .IX Item "$self->enable ($hook_name => $cb, [$hook_name => $cb..])"
377 Dynamically enable the given hooks (named without the \f(CW\*(C`on_\*(C'\fR prefix) for
378 this extension, replacing any previous hook. This is useful when you want
379 to overwrite time-critical hooks only temporarily.
380 .ie n .IP "$self\->disable ($hook_name[, $hook_name..])" 4
381 .el .IP "$self\->disable ($hook_name[, \f(CW$hook_name\fR..])" 4
382 .IX Item "$self->disable ($hook_name[, $hook_name..])"
383 Dynamically disable the given hooks.
384 .Sh "Hooks"
385 .IX Subsection "Hooks"
386 The following subroutines can be declared in extension files, and will be
387 called whenever the relevant event happens.
388 .PP
389 The first argument passed to them is an extension oject as described in
390 the in the \f(CW\*(C`Extension Objects\*(C'\fR section.
391 .PP
392 \&\fBAll\fR of these hooks must return a boolean value. If it is true, then the
393 event counts as being \fIconsumed\fR, and the invocation of other hooks is
394 skipped, and the relevant action might not be carried out by the \*(C+ code.
395 .PP
396 \&\fIWhen in doubt, return a false value (preferably \f(CI\*(C`()\*(C'\fI).\fR
397 .ie n .IP "on_init $term" 4
398 .el .IP "on_init \f(CW$term\fR" 4
399 .IX Item "on_init $term"
400 Called after a new terminal object has been initialized, but before
401 windows are created or the command gets run. Most methods are unsafe to
402 call or deliver senseless data, as terminal size and other characteristics
403 have not yet been determined. You can safely query and change resources,
404 though.
405 .ie n .IP "on_reset $term" 4
406 .el .IP "on_reset \f(CW$term\fR" 4
407 .IX Item "on_reset $term"
408 Called after the screen is \*(L"reset\*(R" for any reason, such as resizing or
409 control sequences. Here is where you can react on changes to size-related
410 variables.
411 .ie n .IP "on_start $term" 4
412 .el .IP "on_start \f(CW$term\fR" 4
413 .IX Item "on_start $term"
414 Called at the very end of initialisation of a new terminal, just before
415 returning to the mainloop.
416 .ie n .IP "on_sel_make $term\fR, \f(CW$eventtime" 4
417 .el .IP "on_sel_make \f(CW$term\fR, \f(CW$eventtime\fR" 4
418 .IX Item "on_sel_make $term, $eventtime"
419 Called whenever a selection has been made by the user, but before the
420 selection text is copied, so changes to the beginning, end or type of the
421 selection will be honored.
422 .Sp
423 Returning a true value aborts selection making by urxvt, in which case you
424 have to make a selection yourself by calling \f(CW\*(C`$term\->selection_grab\*(C'\fR.
425 .ie n .IP "on_sel_grab $term\fR, \f(CW$eventtime" 4
426 .el .IP "on_sel_grab \f(CW$term\fR, \f(CW$eventtime\fR" 4
427 .IX Item "on_sel_grab $term, $eventtime"
428 Called whenever a selection has been copied, but before the selection is
429 requested from the server. The selection text can be queried and changed
430 by calling \f(CW\*(C`$term\->selection\*(C'\fR.
431 .Sp
432 Returning a true value aborts selection grabbing. It will still be hilighted.
433 .ie n .IP "on_sel_extend $term" 4
434 .el .IP "on_sel_extend \f(CW$term\fR" 4
435 .IX Item "on_sel_extend $term"
436 Called whenever the user tries to extend the selection (e.g. with a double
437 click) and is either supposed to return false (normal operation), or
438 should extend the selection itelf and return true to suppress the built-in
439 processing. This can happen multiple times, as long as the callback
440 returns true, it will be called on every further click by the user and is
441 supposed to enlarge the selection more and more, if possible.
442 .Sp
443 See the \fIselection\fR example extension.
