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
175To avoid too many false positives, this is only done when:
176
177=over 4
178
179=item - the mouse is on the same (multi-row-) line as the text cursor.
180
181=item - the primary screen is currently being displayed.
182
183=item - the text cursor is visible.
184
185=back
186
187The normal selection mechanism isn't disabled, so quick successive clicks
188might interfere with selection creation in harmless ways.
189
190=item tabbed
191
192This transforms the terminal into a tabbar with additional terminals, that
193is, it implements what is commonly refered to as "tabbed terminal". The topmost line
194displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
195button per tab.
196
197Clicking a button will activate that tab. Pressing B<Shift-Left> and
198B<Shift-Right> will switch to the tab left or right of the current one,
199while B<Shift-Down> creates a new tab.

89Uses per-line display filtering (C<on_line_update>) to underline urls. 203Uses per-line display filtering (C<on_line_update>) to underline urls and
204make them clickable. When middle-clicked, the program specified in the
205resource C<urlLauncher> (default C<x-www-browser>) will be started with
206the URL as first argument.
207
208=item automove-background
209
210This is basically a one-line extension that dynamically changes the background pixmap offset
211to the window position, in effect creating the same effect as pseudo transparency with
212a custom pixmap. No scaling is supported in this mode. Exmaple:

231
232=item selection-pastebin
233
234This is a little rarely useful extension that Uploads the selection as
235textfile to a remote site (or does other things). (The implementation is
236not currently secure for use in a multiuser environment as it writes to
237F</tmp> directly.).
238
239It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
240i.e.
241
242 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
243
244Pressing this combination runs a command with C<%> replaced by the name of
245the textfile. This command can be set via a resource:
246
247 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
248
249And the default is likely not useful to anybody but the few people around
250here :)
251
252The name of the textfile is the hex encoded md5 sum of the selection, so
253the same content should lead to the same filename.
254
255After a successful upload the selection will be replaced by the text given
256in the C<selection-pastebin-url> resource (again, the % is the placeholder
257for the filename):

382if the new instance couldn't be created. Returns C<undef> if the new

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

569
570=over 4
571
572=item $urxvt::LIBDIR
573
574The rxvt-unicode library directory, where, among other things, the perl
575modules and scripts are stored.
576
577=item $urxvt::RESCLASS, $urxvt::RESCLASS
578
579The resource class and name rxvt-unicode uses to look up X resources.
580
581=item $urxvt::RXVTNAME
582
583The basename of the installed binaries, usually C<urxvt>.
584
585=item $urxvt::TERM
586
587The current terminal. This variable stores the current C<urxvt::term>
588object, whenever a callback/hook is executing.
589
590=item @urxvt::TERM_INIT
591
592All coderefs in this array will be called as methods of the next newly
593created C<urxvt::term> object (during the C<on_init> phase). The array
594gets cleared before the codereferences that were in it are being executed,
595so coderefs can push themselves onto it again if they so desire.
596
597This complements to the perl-eval commandline option, but gets executed
598first.
599
600=item @urxvt::TERM_EXT
601
602Works similar to C<@TERM_INIT>, but contains perl package/class names, which
603get registered as normal extensions after calling the hooks in C<@TERM_INIT>
604but before other extensions. Gets cleared just like C<@TERM_INIT>.

613
614Fatally aborts execution with the given error message. Avoid at all
615costs! The only time this is acceptable is when the terminal process
616starts up.
617
618=item urxvt::warn $string
619
620Calls C<rxvt_warn> with the given string which should not include a
621newline. The module also overwrites the C<warn> builtin with a function
622that calls this function.
623
624Using this function has the advantage that its output ends up in the
625correct place, e.g. on stderr of the connecting urxvtc client.
626
627Messages have a size limit of 1023 bytes currently.
628

659=head2 RENDITION
660
661Rendition bitsets contain information about colour, font, font styles and
662similar information for each screen cell.
663
664The following "macros" deal with changes in rendition sets. You should
665never just create a bitset, you should always modify an existing one,
666as they contain important information required for correct operation of
667rxvt-unicode.
668
669=over 4
670
671=item $rend = urxvt::DEFAULT_RSTYLE
672
673Returns the default rendition, as used when the terminal is starting up or
674being reset. Useful as a base to start when creating renditions.
675
676=item $rend = urxvt::OVERLAY_RSTYLE
677
678Return the rendition mask used for overlays by default.
679
680=item $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
681
682Return the bit that enabled bold, italic, blink, reverse-video and
683underline, respectively. To enable such a style, just logically OR it into
684the bitset.
685
686=item $foreground = urxvt::GET_BASEFG $rend
687
688=item $background = urxvt::GET_BASEBG $rend
689
690Return the foreground/background colour index, respectively.
691
692=item $rend = urxvt::SET_FGCOLOR $rend, $new_colour
693
694=item $rend = urxvt::SET_BGCOLOR $rend, $new_colour
695
696Replace the foreground/background colour in the rendition mask with the
697specified one.
698
699=item $value = urxvt::GET_CUSTOM $rend
700
701Return the "custom" value: Every rendition has 5 bits for use by
702extensions. They can be set and changed as you like and are initially
703zero.
704
705=item $rend = urxvt::SET_CUSTOM $rend, $new_value
