48 53
49It also offers the following bindable event: 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.

70 97
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:
111
112 push @{ $self->{term}{selection_popup_hook} }, sub {
113 /a/ ? ("a to be" => sub { s/a/b/g }

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.
80 131
81Displays a digital clock using the built-in overlay. 132=item selection-autotransform
133
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 tabbed
168
169This transforms the terminal into a tabbar with additional terminals, that
170is, it implements what is commonly refered to as "tabbed terminal". The topmost line
171displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
172button per tab.
173
174Clicking a button will activate that tab. Pressing B<Shift-Left> and
175B<Shift-Right> will switch to the tab left or right of the current one,
176while B<Shift-Down> creates a new tab.

181make them clickable. When middle-clicked, the program specified in the
182resource C<urlLauncher> (default C<x-www-browser>) will be started with
183the URL as first argument.
184
185=item automove-background
186
187This is basically a one-line extension that dynamically changes the background pixmap offset
188to the window position, in effect creating the same effect as pseudo transparency with
189a custom pixmap. No scaling is supported in this mode. Exmaple:

98 208
209=item selection-pastebin
210
211This is a little rarely useful extension that Uploads the selection as
212textfile to a remote site (or does other things). (The implementation is
213not currently secure for use in a multiuser environment as it writes to
214F</tmp> directly.).
215
216It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
217i.e.
218
219 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
220
221Pressing this combination runs a command with C<%> replaced by the name of
222the textfile. This command can be set via a resource:
223
224 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
225
226And the default is likely not useful to anybody but the few people around
227here :)
228
229The name of the textfile is the hex encoded md5 sum of the selection, so
230the same content should lead to the same filename.
231
232After a successful upload the selection will be replaced by the text given
233in the C<selection-pastebin-url> resource (again, the % is the placeholder
234for the filename):

361if the new instance couldn't be created. Returns C<undef> if the new

544
545=over 4
546
547=item $urxvt::LIBDIR
548
549The rxvt-unicode library directory, where, among other things, the perl
550modules and scripts are stored.
551
552=item $urxvt::RESCLASS, $urxvt::RESCLASS
553
554The resource class and name rxvt-unicode uses to look up X resources.
555
556=item $urxvt::RXVTNAME
557
558The basename of the installed binaries, usually C<urxvt>.
559
560=item $urxvt::TERM
561
562The current terminal. This variable stores the current C<urxvt::term>
563object, whenever a callback/hook is executing.
564
565=item @urxvt::TERM_INIT
566
567All coderefs in this array will be called as methods of the next newly
568created C<urxvt::term> object (during the C<on_init> phase). The array
569gets cleared before the codereferences that were in it are being executed,
570so coderefs can push themselves onto it again if they so desire.
571
572This complements to the perl-eval commandline option, but gets executed
573first.
574
575=item @urxvt::TERM_EXT
576
577Works similar to C<@TERM_INIT>, but contains perl package/class names, which
578get registered as normal extensions after calling the hooks in C<@TERM_INIT>
579but before other extensions. Gets cleared just like C<@TERM_INIT>.

587=item urxvt::fatal $errormessage
588
589Fatally aborts execution with the given error message. Avoid at all
590costs! The only time this is acceptable is when the terminal process
591starts up.
592
593=item urxvt::warn $string
594
595Calls C<rxvt_warn> with the given string which should not include a
596newline. The module also overwrites the C<warn> builtin with a function
597that calls this function.
598
599Using this function has the advantage that its output ends up in the
600correct place, e.g. on stderr of the connecting urxvtc client.
601
602Messages have a size limit of 1023 bytes currently.
603

634=head2 RENDITION
635
636Rendition bitsets contain information about colour, font, font styles and
637similar information for each screen cell.
638
639The following "macros" deal with changes in rendition sets. You should
640never just create a bitset, you should always modify an existing one,
641as they contain important information required for correct operation of
642rxvt-unicode.
643
644=over 4
645
646=item $rend = urxvt::DEFAULT_RSTYLE
647
648Returns the default rendition, as used when the terminal is starting up or
649being reset. Useful as a base to start when creating renditions.
650
651=item $rend = urxvt::OVERLAY_RSTYLE
652
653Return the rendition mask used for overlays by default.
654
655=item $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
656
657Return the bit that enabled bold, italic, blink, reverse-video and
658underline, respectively. To enable such a style, just logically OR it into
659the bitset.
660
661=item $foreground = urxvt::GET_BASEFG $rend
662
663=item $background = urxvt::GET_BASEBG $rend
664
665Return the foreground/background colour index, respectively.
666
667=item $rend = urxvt::SET_FGCOLOR $rend, $new_colour
668
669=item $rend = urxvt::SET_BGCOLOR $rend, $new_colour
670
671Replace the foreground/background colour in the rendition mask with the
672specified one.
673
674=item $value = urxvt::GET_CUSTOM $rend
675
676Return the "custom" value: Every rendition has 5 bits for use by
677extensions. They can be set and changed as you like and are initially
678zero.
679
680=item $rend = urxvt::SET_CUSTOM $rend, $new_value
681
682Change the custom value.
