48 53
54A double-click usually selects the word under the cursor, further clicks
55will enlarge the selection.
56
57The selection works by trying to match a number of regexes and displaying
58them in increasing order of length. You can add your own regexes by
59specifying resources of the form:
60
61 URxvt.selection.pattern-0: perl-regex
62 URxvt.selection.pattern-1: perl-regex
63 ...
64
65The index number (0, 1...) must not have any holes, and each regex must
66contain at least one pair of capturing parentheses, which will be used for
67the match. For example, the followign adds a regex that matches everything
68between two vertical bars:
69
70 URxvt.selection.pattern-0: \\|([^|]+)\\|
71
72You can look at the source of the selection extension to see more
73interesting uses, such as parsing a line from beginning to end.

98Other extensions can extend this popup menu by pushing a code reference
99onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
100popup is displayed.
101
102It's sole argument is the popup menu, which can be modified. The selection
103is in C<$_>, which can be used to decide wether to add something or not.
104It should either return nothing or a string and a code reference. The
105string will be used as button text and the code reference will be called
106when the button gets activated and should transform C<$_>.
107
108The following will add an entry C<a to b> that transforms all C<a>s in
109the selection to C<b>s, but only if the selection currently contains any
110C<a>s:

128was started, while C<Enter> or C<Return> stay at the current position and
129additionally stores the first match in the current line into the primary
130selection.
82 131
83=item digital-clock 132=item selection-autotransform
84 133
85Displays a digital clock using the built-in overlay. 134This selection allows you to do automatic transforms on a selection
135whenever a selection is made.
136
137It works by specifying perl snippets (most useful is a single C<s///>
138operator) that modify C<$_> as resources:
139
140 URxvt.selection-autotransform.0: transform
141 URxvt.selection-autotransform.1: transform
142 ...
143
144For example, the following will transform selections of the form
145C<filename:number>, often seen in compiler messages, into C<vi +$filename
146$word>:
147
148 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
149
150And this example matches the same,but replaces it with vi-commands you can
151paste directly into your (vi :) editor:
152
153 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
154
155Of course, this can be modified to suit your needs and your editor :)
156
157To expand the example above to typical perl error messages ("XXX at
158FILENAME line YYY."), you need a slightly more elaborate solution:
159
160 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
161 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
162
163The first line tells the selection code to treat the unchanging part of
164every error message as a selection pattern, and the second line transforms
165the message into vi commands to load the file.
166
167=item readline
168
169A support package that tries to make editing with readline easier. At the
170moment, it reacts to clicking with the left mouse button by trying to
171move the text cursor to this position. It does so by generating as many
172cursor-left or cursor-right keypresses as required (the this only works
173for programs that correctly support wide characters).
174
175It only works when clicking into the same line (possibly extended over
176multiple rows) as the text cursor and on the primary screen, to reduce the
177risk of misinterpreting. The normal selection isn't disabled, so quick
178successive clicks might interfere with selection creation in harmless
179ways.
180
181=item tabbed
182
183This transforms the terminal into a tabbar with additional terminals, that
184is, it implements what is commonly refered to as "tabbed terminal". The topmost line
185displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
186button per tab.
187
188Clicking a button will activate that tab. Pressing B<Shift-Left> and
189B<Shift-Right> will switch to the tab left or right of the current one,
190while B<Shift-Down> creates a new tab.
86 191
87=item mark-urls 192=item mark-urls
88 193
89Uses per-line display filtering (C<on_line_update>) to underline urls. 194Uses per-line display filtering (C<on_line_update>) to underline urls and
195make them clickable. When middle-clicked, the program specified in the
196resource C<urlLauncher> (default C<x-www-browser>) will be started with
197the URL as first argument.
198
199=item automove-background
200
201This is basically a one-line extension that dynamically changes the background pixmap offset
202to the window position, in effect creating the same effect as pseudo transparency with
203a custom pixmap. No scaling is supported in this mode. Exmaple:

222
223=item selection-pastebin
224
225This is a little rarely useful extension that Uploads the selection as
226textfile to a remote site (or does other things). (The implementation is
227not currently secure for use in a multiuser environment as it writes to
228F</tmp> directly.).
229
230It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
231i.e.
232
233 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
234
235Pressing this combination runs a command with C<%> replaced by the name of
236the textfile. This command can be set via a resource:
237
238 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
239
240And the default is likely not useful to anybody but the few people around
241here :)
242
243The name of the textfile is the hex encoded md5 sum of the selection, so
244the same content should lead to the same filename.
245
246After a successful upload the selection will be replaced by the text given
247in the C<selection-pastebin-url> resource (again, the % is the placeholder
248for the filename):

380Creates a new terminal, very similar as if you had started it with
381C<system $binfile, arg...>. Croaks (and probably outputs an error message)
382if the new instance couldn't be created. Returns C<undef> if the new
383instance didn't initialise perl, and the terminal object otherwise. The

391
392=item urxvt::warn $string
393
394Calls C<rxvt_warn> with the given string which should not include a
395newline. The module also overwrites the C<warn> builtin with a function
396that calls this function.
397
398Using this function has the advantage that its output ends up in the

559=head2 Variables in the C<urxvt> Package
560
561=over 4
562
563=item $urxvt::LIBDIR
564
565The rxvt-unicode library directory, where, among other things, the perl
566modules and scripts are stored.
567
568=item $urxvt::RESCLASS, $urxvt::RESCLASS
569
570The resource class and name rxvt-unicode uses to look up X resources.
571
572=item $urxvt::RXVTNAME
573
574The basename of the installed binaries, usually C<urxvt>.
575
576=item $urxvt::TERM
577
578The current terminal. This variable stores the current C<urxvt::term>
579object, whenever a callback/hook is executing.
580
581=item @urxvt::TERM_INIT
582
583All coderefs in this array will be called as methods of the next newly
584created C<urxvt::term> object (during the C<on_init> phase). The array
585gets cleared before the codereferences that were in it are being executed,
586so coderefs can push themselves onto it again if they so desire.
587
588This complements to the perl-eval commandline option, but gets executed
589first.
590
591=item @urxvt::TERM_EXT
592
593Works similar to C<@TERM_INIT>, but contains perl package/class names, which
594get registered as normal extensions after calling the hooks in C<@TERM_INIT>
595but before other extensions. Gets cleared just like C<@TERM_INIT>.

603=item urxvt::fatal $errormessage
604
605Fatally aborts execution with the given error message. Avoid at all
606costs! The only time this is acceptable is when the terminal process
607starts up.
608
609=item urxvt::warn $string
610
611Calls C<rxvt_warn> with the given string which should not include a
612newline. The module also overwrites the C<warn> builtin with a function
613that calls this function.
614
615Using this function has the advantage that its output ends up in the
616correct place, e.g. on stderr of the connecting urxvtc client.
617
618Messages have a size limit of 1023 bytes currently.
619

650=head2 RENDITION
651
652Rendition bitsets contain information about colour, font, font styles and
653similar information for each screen cell.
654
655The following "macros" deal with changes in rendition sets. You should
656never just create a bitset, you should always modify an existing one,
657as they contain important information required for correct operation of
658rxvt-unicode.
659
660=over 4
661
662=item $rend = urxvt::DEFAULT_RSTYLE
663
664Returns the default rendition, as used when the terminal is starting up or
665being reset. Useful as a base to start when creating renditions.
666
667=item $rend = urxvt::OVERLAY_RSTYLE
668
669Return the rendition mask used for overlays by default.
670
671=item $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
672
673Return the bit that enabled bold, italic, blink, reverse-video and
674underline, respectively. To enable such a style, just logically OR it into
675the bitset.
676
677=item $foreground = urxvt::GET_BASEFG $rend
678
679=item $background = urxvt::GET_BASEBG $rend
680
681Return the foreground/background colour index, respectively.
682
683=item $rend = urxvt::SET_FGCOLOR $rend, $new_colour
684
685=item $rend = urxvt::SET_BGCOLOR $rend, $new_colour
686
687Replace the foreground/background colour in the rendition mask with the
688specified one.
689
690=item $value = urxvt::GET_CUSTOM $rend
691
692Return the "custom" value: Every rendition has 5 bits for use by
693extensions. They can be set and changed as you like and are initially
694zero.
695
696=item $rend = urxvt::SET_CUSTOM $rend, $new_value
