170     This section describes the extensions delivered with this release. You can

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

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

238 root 1.16 .IP "option-popup (enabled by default)" 4
239     .IX Item "option-popup (enabled by default)"
240 root 1.17 Binds a popup menu to Ctrl\-Button2 that lets you toggle (some) options at
241 root 1.16 runtime.
242 root 1.44 .Sp
243     Other extensions can extend this popup menu by pushing a code reference
244     onto \f(CW\*(C`@{ $term\-\*(C'\fR{option_popup_hook} }>, which gets called whenever the
245     popup is being displayed.
246     .Sp
247     It's sole argument is the popup menu, which can be modified. It should
248     either return nothing or a string, the initial boolean value and a code
249     reference. The string will be used as button text and the code reference
250     will be called when the toggle changes, with the new boolean value as
251     first argument.
252     .Sp
253     The following will add an entry \f(CW\*(C`myoption\*(C'\fR that changes
254     \&\f(CW\*(C`$self\-\*(C'\fR{myoption}>:
255     .Sp
256     .Vb 3
257 root 1.50 \& push @{ $self->{term}{option_popup_hook} }, sub {
258     \& ("my option" => $myoption, sub { $self->{myoption} = $_[0] })
259 root 1.44 \& };
260     .Ve
261 root 1.17 .IP "selection-popup (enabled by default)" 4
262     .IX Item "selection-popup (enabled by default)"
263     Binds a popup menu to Ctrl\-Button3 that lets you convert the selection
264 root 1.20 text into various other formats/action (such as uri unescaping, perl
265 root 1.36 evaluation, web-browser starting etc.), depending on content.
266 root 1.34 .Sp
267     Other extensions can extend this popup menu by pushing a code reference
268 root 1.44 onto \f(CW\*(C`@{ $term\-\*(C'\fR{selection_popup_hook} }>, which gets called whenever the
269     popup is being displayed.
270 root 1.34 .Sp
271     It's sole argument is the popup menu, which can be modified. The selection
272 root 1.49 is in \f(CW$_\fR, which can be used to decide whether to add something or not.
273 root 1.34 It should either return nothing or a string and a code reference. The
274     string will be used as button text and the code reference will be called
275     when the button gets activated and should transform \f(CW$_\fR.
276     .Sp
277     The following will add an entry \f(CW\*(C`a to b\*(C'\fR that transforms all \f(CW\*(C`a\*(C'\fRs in
278     the selection to \f(CW\*(C`b\*(C'\fRs, but only if the selection currently contains any
279     \&\f(CW\*(C`a\*(C'\fRs:
280     .Sp
281     .Vb 4
282 root 1.50 \& push @{ $self->{term}{selection_popup_hook} }, sub {
283 root 1.34 \& /a/ ? ("a to be" => sub { s/a/b/g }
284     \& : ()
285     \& };
286     .Ve
287 root 1.19 .IP "searchable\-scrollback<hotkey> (enabled by default)" 4
288     .IX Item "searchable-scrollback<hotkey> (enabled by default)"
289     Adds regex search functionality to the scrollback buffer, triggered
290 root 1.25 by a hotkey (default: \f(CW\*(C`M\-s\*(C'\fR). While in search mode, normal terminal
291     input/output is suspended and a regex is displayed at the bottom of the
292     screen.
293     .Sp
294     Inputting characters appends them to the regex and continues incremental
295     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
296     search upwards/downwards in the scrollback buffer, \f(CW\*(C`End\*(C'\fR jumps to the
297     bottom. \f(CW\*(C`Escape\*(C'\fR leaves search mode and returns to the point where search
298     was started, while \f(CW\*(C`Enter\*(C'\fR or \f(CW\*(C`Return\*(C'\fR stay at the current position and
299     additionally stores the first match in the current line into the primary
300 root 1.56 selection if the \f(CW\*(C`Shift\*(C'\fR modifier is active.
301 root 1.47 .Sp
302     The regex defaults to \*(L"(?i)\*(R", resulting in a case-insensitive search. To
303     get a case-sensitive search you can delete this prefix using \f(CW\*(C`BackSpace\*(C'\fR
304     or simply use an uppercase character which removes the \*(L"(?i)\*(R" prefix.
305     .Sp
306     See perlre for more info about perl regular expression syntax.
307 root 1.37 .IP "readline (enabled by default)" 4
308     .IX Item "readline (enabled by default)"
309 root 1.46 A support package that tries to make editing with readline easier. At
310     the moment, it reacts to clicking shift-left mouse button by trying to
311 root 1.37 move the text cursor to this position. It does so by generating as many
312     cursor-left or cursor-right keypresses as required (the this only works
313     for programs that correctly support wide characters).
314     .Sp
315     To avoid too many false positives, this is only done when:
316     .RS 4
317 root 1.38 .IP "\- the tty is in \s-1ICANON\s0 state." 4
318     .IX Item "- the tty is in ICANON state."

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

484     Somewhat of a misnomer, this extension adds two menu entries to the

488     We use it to implement a \*(L"distributed selection mechanism\*(R", which just
489     means that one command uploads the file to a remote server, and another

492     The commands can be set using the \f(CW\*(C`URxvt.remote\-selection.store\*(C'\fR and
493     \&\f(CW\*(C`URxvt.remote\-selection.fetch\*(C'\fR resources. The first should read the

530     After a successful upload the selection will be replaced by the text given
531     in the \f(CW\*(C`selection\-pastebin\-url\*(C'\fR resource (again, the % is the placeholder
