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.

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.
169 .PP
170 You can activate them like this:

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:

220 .IP "option-popup (enabled by default)" 4
221 .IX Item "option-popup (enabled by default)"
222 Binds a popup menu to Ctrl\-Button2 that lets you toggle (some) options at
223 runtime.
224 .IP "selection-popup (enabled by default)" 4
225 .IX Item "selection-popup (enabled by default)"
226 Binds a popup menu to Ctrl\-Button3 that lets you convert the selection
227 text into various other formats/action (such as uri unescaping, perl
228 evalution, web-browser starting etc.), depending on content.
229 .IP "searchable\-scrollback<hotkey> (enabled by default)" 4
230 .IX Item "searchable-scrollback<hotkey> (enabled by default)"
231 Adds regex search functionality to the scrollback buffer, triggered
232 by a hotkey (default: \f(CW\*(C`M\-s\*(C'\fR). While in search mode, normal terminal
233 input/output is suspended and a regex is displayed at the bottom of the
234 screen.
235 .Sp
236 Inputting characters appends them to the regex and continues incremental
237 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
238 search upwards/downwards in the scrollback buffer, \f(CW\*(C`End\*(C'\fR jumps to the
239 bottom. \f(CW\*(C`Escape\*(C'\fR leaves search mode and returns to the point where search
240 was started, while \f(CW\*(C`Enter\*(C'\fR or \f(CW\*(C`Return\*(C'\fR stay at the current position and
241 additionally stores the first match in the current line into the primary
242 selection.
243 .IP "selection-autotransform" 4
244 .IX Item "selection-autotransform"
245 This selection allows you to do automatic transforms on a selection
246 whenever a selection is made.
247 .Sp
248 It works by specifying perl snippets (most useful is a single \f(CW\*(C`s///\*(C'\fR
249 operator) that modify \f(CW$_\fR as resources:
250 .Sp
251 .Vb 3
252 \& URxvt.selection-autotransform.0: transform
253 \& URxvt.selection-autotransform.1: transform
254 \& ...
255 .Ve
256 .Sp
257 For example, the following will transform selections of the form
258 \&\f(CW\*(C`filename:number\*(C'\fR, often seen in compiler messages, into \f(CW\*(C`vi +$filename
259 $word\*(C'\fR:
260 .Sp
261 .Vb 1
262 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\e\ed+):?$/vi +$2 \e\eQ$1\e\eE\e\ex0d/
263 .Ve
264 .Sp
265 And this example matches the same,but replaces it with vi-commands you can
266 paste directly into your (vi :) editor:
267 .Sp
268 .Vb 1
269 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\e\ed+):?$/\e\ex1b:e \e\eQ$1\e\eE\e\ex0d:$2\e\ex0d/
270 .Ve
271 .Sp
272 Of course, this can be modified to suit your needs and your editor :)
273 .Sp
274 To expand the example above to typical perl error messages (\*(L"\s-1XXX\s0 at
275 \&\s-1FILENAME\s0 line \s-1YYY\s0.\*(R"), you need a slightly more elaborate solution:
276 .Sp
277 .Vb 2
278 \& URxvt.selection.pattern-0: ( at .*? line \e\ed+\e\e.)
279 \& URxvt.selection-autotransform.0: s/^ at (.*?) line (\e\ed+)\e\e.$/\ex1b:e \e\eQ$1\eE\e\ex0d:$2\e\ex0d/
280 .Ve
281 .Sp
282 The first line tells the selection code to treat the unchanging part of
283 every error message as a selection pattern, and the second line transforms
284 the message into vi commands to load the file.
285 .IP "mark-urls" 4
286 .IX Item "mark-urls"
287 Uses per-line display filtering (\f(CW\*(C`on_line_update\*(C'\fR) to underline urls and
288 make them clickable. When middle\-clicked, the program specified in the
289 resource \f(CW\*(C`urlLauncher\*(C'\fR (default \f(CW\*(C`x\-www\-browser\*(C'\fR) will be started with
290 the \s-1URL\s0 as first argument.
291 .IP "block-graphics-to-ascii" 4
292 .IX Item "block-graphics-to-ascii"
293 A not very useful example of filtering all text output to the terminal,
294 by replacing all line-drawing characters (U+2500 .. U+259F) by a
295 similar-looking ascii character.
296 .IP "digital-clock" 4
297 .IX Item "digital-clock"
298 Displays a digital clock using the built-in overlay.
299 .IP "example-refresh-hooks" 4
300 .IX Item "example-refresh-hooks"
301 Displays a very simple digital clock in the upper right corner of the
302 window. Illustrates overwriting the refresh callbacks to create your own
303 overlays or changes.
304 .IP "selection-pastebin" 4
305 .IX Item "selection-pastebin"
306 This is a little rarely useful extension that Uploads the selection as
307 textfile to a remote site (or does other things). (The implementation is
308 not currently secure for use in a multiuser environment as it writes to
309 \&\fI/tmp\fR directly.).
310 .Sp
311 It listens to the \f(CW\*(C`selection\-pastebin:remote\-pastebin\*(C'\fR keyboard command,
312 i.e.
313 .Sp
314 .Vb 1
315 \& URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
316 .Ve
317 .Sp
318 Pressing this combination runs a command with \f(CW\*(C`%\*(C'\fR replaced by the name of
319 the textfile. This command can be set via a resource:
320 .Sp
321 .Vb 1
322 \& URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
323 .Ve
324 .Sp
325 And the default is likely not useful to anybody but the few people around
326 here :)
327 .Sp
328 The name of the textfile is the hex encoded md5 sum of the selection, so
329 the same content should lead to the same filename.
330 .Sp
331 After a successful upload the selection will be replaced by the text given
332 in the \f(CW\*(C`selection\-pastebin\-url\*(C'\fR resource (again, the % is the placeholder
333 for the filename):
334 .Sp
335 .Vb 1
336 \& URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
337 .Ve

341 .IX Subsection "General API Considerations"
342 All objects (such as terminals, time watchers etc.) are typical
343 reference-to-hash objects. The hash can be used to store anything you
344 like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or
345 \&\f(CW\*(C`_hook\*(C'\fR) are reserved for internal uses and \fB\s-1MUST\s0 \s-1NOT\s0\fR be accessed or
346 modified).
347 .PP
348 When objects are destroyed on the \*(C+ side, the perl object hashes are
349 emptied, so its best to store related objects such as time watchers and
350 the like inside the terminal object so they get destroyed as soon as the
351 terminal is destroyed.
352 .PP
353 Argument names also often indicate the type of a parameter. Here are some
354 hints on what they mean:
355 .IP "$text" 4
356 .IX Item "$text"
357 Rxvt-unicodes special way of encoding text, where one \*(L"unicode\*(R" character
358 always represents one screen cell. See ROW_t for a discussion of this format.
359 .IP "$string" 4
360 .IX Item "$string"
361 A perl text string, with an emphasis on \fItext\fR. It can store all unicode
362 characters and is to be distinguished with text encoded in a specific
363 encoding (often locale\-specific) and binary data.
364 .IP "$octets" 4
365 .IX Item "$octets"
366 Either binary data or \- more common \- a text string encoded in a
367 locale-specific way.
368 .Sh "Extension Objects"
369 .IX Subsection "Extension Objects"
370 Very perl extension is a perl class. A separate perl object is created
371 for each terminal and each extension and passed as the first parameter to
372 hooks. So extensions can use their \f(CW$self\fR object without having to think
373 about other extensions, with the exception of methods and members that
374 begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for internal
375 use.
376 .PP
377 Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the
378 \&\f(CW\*(C`urxvt::term\*(C'\fR class on this object.
379 .PP
380 It has the following methods and data members:
381 .ie n .IP "$urxvt_term = $self\->{term}" 4
382 .el .IP "$urxvt_term = \f(CW$self\fR\->{term}" 4
383 .IX Item "$urxvt_term = $self->{term}"
384 Returns the \f(CW\*(C`urxvt::term\*(C'\fR object associated with this instance of the
385 extension. This member \fImust not\fR be changed in any way.
386 .ie n .IP "$self\->enable ($hook_name => $cb\fR, [$hook_name => \f(CW$cb..])" 4
387 .el .IP "$self\->enable ($hook_name => \f(CW$cb\fR, [$hook_name => \f(CW$cb\fR..])" 4
388 .IX Item "$self->enable ($hook_name => $cb, [$hook_name => $cb..])"
389 Dynamically enable the given hooks (named without the \f(CW\*(C`on_\*(C'\fR prefix) for
390 this extension, replacing any previous hook. This is useful when you want
391 to overwrite time-critical hooks only temporarily.
392 .ie n .IP "$self\->disable ($hook_name[, $hook_name..])" 4
393 .el .IP "$self\->disable ($hook_name[, \f(CW$hook_name\fR..])" 4
394 .IX Item "$self->disable ($hook_name[, $hook_name..])"
395 Dynamically disable the given hooks.
396 .Sh "Hooks"
397 .IX Subsection "Hooks"
398 The following subroutines can be declared in extension files, and will be
399 called whenever the relevant event happens.
400 .PP
401 The first argument passed to them is an extension oject as described in
402 the in the \f(CW\*(C`Extension Objects\*(C'\fR section.
403 .PP
404 \&\fBAll\fR of these hooks must return a boolean value. If it is true, then the
405 event counts as being \fIconsumed\fR, and the invocation of other hooks is
406 skipped, and the relevant action might not be carried out by the \*(C+ code.
407 .PP
408 \&\fIWhen in doubt, return a false value (preferably \f(CI\*(C`()\*(C'\fI).\fR
409 .ie n .IP "on_init $term" 4
410 .el .IP "on_init \f(CW$term\fR" 4
411 .IX Item "on_init $term"
412 Called after a new terminal object has been initialized, but before
413 windows are created or the command gets run. Most methods are unsafe to
414 call or deliver senseless data, as terminal size and other characteristics
415 have not yet been determined. You can safely query and change resources,
416 though.
417 .ie n .IP "on_reset $term" 4
418 .el .IP "on_reset \f(CW$term\fR" 4
419 .IX Item "on_reset $term"
420 Called after the screen is \*(L"reset\*(R" for any reason, such as resizing or
421 control sequences. Here is where you can react on changes to size-related
422 variables.
423 .ie n .IP "on_start $term" 4
424 .el .IP "on_start \f(CW$term\fR" 4
425 .IX Item "on_start $term"
426 Called at the very end of initialisation of a new terminal, just before
427 returning to the mainloop.
428 .ie n .IP "on_sel_make $term\fR, \f(CW$eventtime" 4
429 .el .IP "on_sel_make \f(CW$term\fR, \f(CW$eventtime\fR" 4
430 .IX Item "on_sel_make $term, $eventtime"
431 Called whenever a selection has been made by the user, but before the
432 selection text is copied, so changes to the beginning, end or type of the
433 selection will be honored.
434 .Sp
435 Returning a true value aborts selection making by urxvt, in which case you
436 have to make a selection yourself by calling \f(CW\*(C`$term\->selection_grab\*(C'\fR.
437 .ie n .IP "on_sel_grab $term\fR, \f(CW$eventtime" 4
438 .el .IP "on_sel_grab \f(CW$term\fR, \f(CW$eventtime\fR" 4
439 .IX Item "on_sel_grab $term, $eventtime"
440 Called whenever a selection has been copied, but before the selection is
441 requested from the server. The selection text can be queried and changed
442 by calling \f(CW\*(C`$term\->selection\*(C'\fR.
443 .Sp
444 Returning a true value aborts selection grabbing. It will still be hilighted.
