167     This section describes the extensions delivered with this release. You can
168 root 1.6 find them in \fI@@RXVT_LIBDIR@@/urxvt/perl/\fR.
169     .PP
170     You can activate them like this:

180 root 1.35 .Ve
181 root 1.16 .IP "selection (enabled by default)" 4
182     .IX Item "selection (enabled by default)"
183 root 1.20 (More) intelligent selection. This extension tries to be more intelligent
184 root 1.25 when the user extends selections (double\-click and further clicks). Right
185     now, it tries to select words, urls and complete shell-quoted
186     arguments, which is very convenient, too, if your \fIls\fR supports
187     \&\f(CW\*(C`\-\-quoting\-style=shell\*(C'\fR.
188     .Sp
189     A double-click usually selects the word under the cursor, further clicks
190     will enlarge the selection.
191 root 1.9 .Sp
192 root 1.26 The selection works by trying to match a number of regexes and displaying
193     them in increasing order of length. You can add your own regexes by
194     specifying resources of the form:
195     .Sp
196     .Vb 3
197 root 1.50 \& URxvt.selection.pattern-0: perl-regex
198     \& URxvt.selection.pattern-1: perl-regex
199 root 1.26 \& ...
200     .Ve
201     .Sp
202     The index number (0, 1...) must not have any holes, and each regex must
203     contain at least one pair of capturing parentheses, which will be used for
204 root 1.49 the match. For example, the following adds a regex that matches everything
205 root 1.26 between two vertical bars:
206     .Sp
207     .Vb 1
208 root 1.50 \& URxvt.selection.pattern-0: \e\e|([^|]+)\e\e|
209 root 1.26 .Ve
210     .Sp
211 root 1.39 Another example: Programs I use often output \*(L"absolute path: \*(R" at the
212     beginning of a line when they process multiple files. The following
213     pattern matches the filename (note, there is a single space at the very
214     end):
215     .Sp
216     .Vb 1
217 root 1.50 \& URxvt.selection.pattern-0: ^(/[^:]+):\e
218 root 1.39 .Ve
219     .Sp
220 root 1.26 You can look at the source of the selection extension to see more
221     interesting uses, such as parsing a line from beginning to end.

235 root 1.16 .IP "option-popup (enabled by default)" 4
236     .IX Item "option-popup (enabled by default)"
237 root 1.17 Binds a popup menu to Ctrl\-Button2 that lets you toggle (some) options at
238 root 1.16 runtime.
239 root 1.44 .Sp
240     Other extensions can extend this popup menu by pushing a code reference
241     onto \f(CW\*(C`@{ $term\-\*(C'\fR{option_popup_hook} }>, which gets called whenever the
242     popup is being displayed.
243     .Sp
244     It's sole argument is the popup menu, which can be modified. It should
245     either return nothing or a string, the initial boolean value and a code
246     reference. The string will be used as button text and the code reference
247     will be called when the toggle changes, with the new boolean value as
248     first argument.
249     .Sp
250     The following will add an entry \f(CW\*(C`myoption\*(C'\fR that changes
251     \&\f(CW\*(C`$self\-\*(C'\fR{myoption}>:
252     .Sp
253     .Vb 3
254 root 1.50 \& push @{ $self->{term}{option_popup_hook} }, sub {
255     \& ("my option" => $myoption, sub { $self->{myoption} = $_[0] })
256 root 1.44 \& };
257     .Ve
258 root 1.17 .IP "selection-popup (enabled by default)" 4
259     .IX Item "selection-popup (enabled by default)"
260     Binds a popup menu to Ctrl\-Button3 that lets you convert the selection
261 root 1.20 text into various other formats/action (such as uri unescaping, perl
262 root 1.36 evaluation, web-browser starting etc.), depending on content.
263 root 1.34 .Sp
264     Other extensions can extend this popup menu by pushing a code reference
265 root 1.44 onto \f(CW\*(C`@{ $term\-\*(C'\fR{selection_popup_hook} }>, which gets called whenever the
266     popup is being displayed.
267 root 1.34 .Sp
268     It's sole argument is the popup menu, which can be modified. The selection
269 root 1.49 is in \f(CW$_\fR, which can be used to decide whether to add something or not.
270 root 1.34 It should either return nothing or a string and a code reference. The
271     string will be used as button text and the code reference will be called
272     when the button gets activated and should transform \f(CW$_\fR.
273     .Sp
274     The following will add an entry \f(CW\*(C`a to b\*(C'\fR that transforms all \f(CW\*(C`a\*(C'\fRs in
275     the selection to \f(CW\*(C`b\*(C'\fRs, but only if the selection currently contains any
276     \&\f(CW\*(C`a\*(C'\fRs:
277     .Sp
278     .Vb 4
279 root 1.50 \& push @{ $self->{term}{selection_popup_hook} }, sub {
280 root 1.34 \& /a/ ? ("a to be" => sub { s/a/b/g }
281     \& : ()
282     \& };
283     .Ve
284 root 1.19 .IP "searchable\-scrollback<hotkey> (enabled by default)" 4
285     .IX Item "searchable-scrollback<hotkey> (enabled by default)"
286     Adds regex search functionality to the scrollback buffer, triggered
287 root 1.25 by a hotkey (default: \f(CW\*(C`M\-s\*(C'\fR). While in search mode, normal terminal
288     input/output is suspended and a regex is displayed at the bottom of the
289     screen.
290     .Sp
291     Inputting characters appends them to the regex and continues incremental
292     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
293     search upwards/downwards in the scrollback buffer, \f(CW\*(C`End\*(C'\fR jumps to the
294     bottom. \f(CW\*(C`Escape\*(C'\fR leaves search mode and returns to the point where search
295     was started, while \f(CW\*(C`Enter\*(C'\fR or \f(CW\*(C`Return\*(C'\fR stay at the current position and
296     additionally stores the first match in the current line into the primary
297     selection.
298 root 1.47 .Sp
299     The regex defaults to \*(L"(?i)\*(R", resulting in a case-insensitive search. To
300     get a case-sensitive search you can delete this prefix using \f(CW\*(C`BackSpace\*(C'\fR
301     or simply use an uppercase character which removes the \*(L"(?i)\*(R" prefix.
302     .Sp
303     See perlre for more info about perl regular expression syntax.
304 root 1.37 .IP "readline (enabled by default)" 4
305     .IX Item "readline (enabled by default)"
306 root 1.46 A support package that tries to make editing with readline easier. At
307     the moment, it reacts to clicking shift-left mouse button by trying to
308 root 1.37 move the text cursor to this position. It does so by generating as many
309     cursor-left or cursor-right keypresses as required (the this only works
310     for programs that correctly support wide characters).
311     .Sp
312     To avoid too many false positives, this is only done when:
313     .RS 4
314 root 1.38 .IP "\- the tty is in \s-1ICANON\s0 state." 4
315     .IX Item "- the tty is in ICANON state."

320     .IX Item "- the primary screen is currently being displayed."
321 root 1.38 .IP "\- the mouse is on the same (multi\-row\-) line as the text cursor." 4
322     .IX Item "- the mouse is on the same (multi-row-) line as the text cursor."
323 root 1.37 .RE
324     .RS 4
325     .PD
326     .Sp
327     The normal selection mechanism isn't disabled, so quick successive clicks
328     might interfere with selection creation in harmless ways.
329     .RE
330 root 1.26 .IP "selection-autotransform" 4
331     .IX Item "selection-autotransform"
332     This selection allows you to do automatic transforms on a selection
333     whenever a selection is made.
334     .Sp
335     It works by specifying perl snippets (most useful is a single \f(CW\*(C`s///\*(C'\fR
336     operator) that modify \f(CW$_\fR as resources:
337     .Sp
338     .Vb 3
339 root 1.50 \& URxvt.selection-autotransform.0: transform
340     \& URxvt.selection-autotransform.1: transform
341 root 1.26 \& ...
342     .Ve
343     .Sp
344     For example, the following will transform selections of the form
345     \&\f(CW\*(C`filename:number\*(C'\fR, often seen in compiler messages, into \f(CW\*(C`vi +$filename
346     $word\*(C'\fR:
347     .Sp
348     .Vb 1
349 root 1.50 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\e\ed+):?$/vi +$2 \e\eQ$1\e\eE\e\ex0d/
350 root 1.26 .Ve
351     .Sp
352     And this example matches the same,but replaces it with vi-commands you can
353     paste directly into your (vi :) editor:
354     .Sp
355     .Vb 1
356 root 1.50 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\e\ed+):?$/:e \e\eQ$1\e\eE\e\ex0d:$2\e\ex0d/
357 root 1.26 .Ve
358 root 1.27 .Sp
359     Of course, this can be modified to suit your needs and your editor :)
360 root 1.28 .Sp
361     To expand the example above to typical perl error messages (\*(L"\s-1XXX\s0 at
362     \&\s-1FILENAME\s0 line \s-1YYY\s0.\*(R"), you need a slightly more elaborate solution:
363     .Sp
364     .Vb 2
365 root 1.50 \& URxvt.selection.pattern-0: ( at .*? line \e\ed+[,.])
366     \& URxvt.selection-autotransform.0: s/^ at (.*?) line (\e\ed+)[,.]$/:e \e\eQ$1\eE\e\ex0d:$2\e\ex0d/
367 root 1.28 .Ve
368     .Sp
369     The first line tells the selection code to treat the unchanging part of
370     every error message as a selection pattern, and the second line transforms
371     the message into vi commands to load the file.
372 root 1.35 .IP "tabbed" 4
373     .IX Item "tabbed"
374     This transforms the terminal into a tabbar with additional terminals, that
375 root 1.49 is, it implements what is commonly referred to as \*(L"tabbed terminal\*(R". The topmost line
376 root 1.35 displays a \*(L"[\s-1NEW\s0]\*(R" button, which, when clicked, will add a new tab, followed by one
377     button per tab.
378     .Sp
379 root 1.36 Clicking a button will activate that tab. Pressing \fBShift-Left\fR and
380     \&\fBShift-Right\fR will switch to the tab left or right of the current one,
381     while \fBShift-Down\fR creates a new tab.
382 root 1.43 .Sp
383     The tabbar itself can be configured similarly to a normal terminal, but
384     with a resource class of \f(CW\*(C`URxvt.tabbed\*(C'\fR. In addition, it supports the
385     following four resources (shown with defaults):
386     .Sp
387     .Vb 4
388 root 1.50 \& URxvt.tabbed.tabbar-fg: <colour-index, default 3>
389     \& URxvt.tabbed.tabbar-bg: <colour-index, default 0>

440     user presses a global accelerator key (by default \f(CW\*(C`F10\*(C'\fR), the terminal

442     or show it again.

444     Initially, the window will not be shown when using this extension.
445     .Sp
446     This is useful if you need a single terminal thats not using any desktop
447     space most of the time but is quickly available at the press of a key.
448     .Sp
449 root 1.49 The accelerator key is grabbed regardless of any modifiers, so this

474     Somewhat of a misnomer, this extension adds two menu entries to the
475     selection popup that allows one ti run external commands to store the
476     selection somewhere and fetch it again.
477     .Sp
478     We use it to implement a \*(L"distributed selection mechanism\*(R", which just
479     means that one command uploads the file to a remote server, and another
480     reads it.
481     .Sp
482     The commands can be set using the \f(CW\*(C`URxvt.remote\-selection.store\*(C'\fR and
483     \&\f(CW\*(C`URxvt.remote\-selection.fetch\*(C'\fR resources. The first should read the
484     selection to store from \s-1STDIN\s0 (always in \s-1UTF\-8\s0), the second should provide
485     the selection data on \s-1STDOUT\s0 (also in \s-1UTF\-8\s0).

516     .Sp
517     The name of the textfile is the hex encoded md5 sum of the selection, so
518     the same content should lead to the same filename.
519     .Sp
520     After a successful upload the selection will be replaced by the text given
521     in the \f(CW\*(C`selection\-pastebin\-url\*(C'\fR resource (again, the % is the placeholder
