52C<--quoting-style=shell>.
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
72Another example: Programs I use often output "absolute path: " at the
73beginning of a line when they process multiple files. The following
74pattern matches the filename (note, there is a single space at the very
75end):
76
77 URxvt.selection.pattern-0: ^(/[^:]+):\
78
79You can look at the source of the selection extension to see more
80interesting uses, such as parsing a line from beginning to end.

69text into various other formats/action. 102text into various other formats/action (such as uri unescaping, perl
103evaluation, web-browser starting etc.), depending on content.
70 104
105Other extensions can extend this popup menu by pushing a code reference
106onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
107popup is displayed.
108
109It's sole argument is the popup menu, which can be modified. The selection
110is in C<$_>, which can be used to decide wether to add something or not.
111It should either return nothing or a string and a code reference. The
112string will be used as button text and the code reference will be called
113when the button gets activated and should transform C<$_>.
114
115The following will add an entry C<a to b> that transforms all C<a>s in
116the selection to C<b>s, but only if the selection currently contains any
117C<a>s:
118
119 push @{ $self->{term}{selection_popup_hook} }, sub {

132search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>

134bottom. C<Escape> leaves search mode and returns to the point where search
135was started, while C<Enter> or C<Return> stay at the current position and
136additionally stores the first match in the current line into the primary
137selection.
80 138
81Displays a digital clock using the built-in overlay. 139=item readline (enabled by default)
140
141A support package that tries to make editing with readline easier. At the
142moment, it reacts to clicking with the left mouse button by trying to
143move the text cursor to this position. It does so by generating as many
144cursor-left or cursor-right keypresses as required (the this only works
145for programs that correctly support wide characters).
146
147To avoid too many false positives, this is only done when:
148
149=over 4
150
151=item - the tty is in ICANON state.
152
153=item - the text cursor is visible.
154
155=item - the primary screen is currently being displayed.
156
157=item - the mouse is on the same (multi-row-) line as the text cursor.
158
159=back
160
161The normal selection mechanism isn't disabled, so quick successive clicks
162might interfere with selection creation in harmless ways.
163
164=item selection-autotransform
165
166This selection allows you to do automatic transforms on a selection
167whenever a selection is made.
168
169It works by specifying perl snippets (most useful is a single C<s///>
170operator) that modify C<$_> as resources:
171
172 URxvt.selection-autotransform.0: transform
173 URxvt.selection-autotransform.1: transform
174 ...
175
176For example, the following will transform selections of the form
177C<filename:number>, often seen in compiler messages, into C<vi +$filename
178$word>:
179
180 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
181
182And this example matches the same,but replaces it with vi-commands you can
183paste directly into your (vi :) editor:
184
185 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
186
187Of course, this can be modified to suit your needs and your editor :)
188
189To expand the example above to typical perl error messages ("XXX at
190FILENAME line YYY."), you need a slightly more elaborate solution:
191
192 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
193 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
194
195The first line tells the selection code to treat the unchanging part of
196every error message as a selection pattern, and the second line transforms
197the message into vi commands to load the file.
198
199=item tabbed
200
201This transforms the terminal into a tabbar with additional terminals, that
202is, it implements what is commonly refered to as "tabbed terminal". The topmost line
203displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
204button per tab.
205
206Clicking a button will activate that tab. Pressing B<Shift-Left> and
207B<Shift-Right> will switch to the tab left or right of the current one,
208while B<Shift-Down> creates a new tab.
82 209
83=item mark-urls 210=item mark-urls
84 211
85Uses per-line display filtering (C<on_line_update>) to underline urls. 212Uses per-line display filtering (C<on_line_update>) to underline urls and
213make them clickable. When middle-clicked, the program specified in the
214resource C<urlLauncher> (default C<x-www-browser>) will be started with
215the URL as first argument.
216
217=item automove-background
218
219This is basically a one-line extension that dynamically changes the background pixmap offset
220to the window position, in effect creating the same effect as pseudo transparency with
221a custom pixmap. No scaling is supported in this mode. Exmaple:

241=item selection-pastebin
242
243This is a little rarely useful extension that Uploads the selection as
244textfile to a remote site (or does other things). (The implementation is
245not currently secure for use in a multiuser environment as it writes to
246F</tmp> directly.).
247
248It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
249i.e.
250
251 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
252
253Pressing this combination runs a command with C<%> replaced by the name of
254the textfile. This command can be set via a resource:
255
256 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
257
258And the default is likely not useful to anybody but the few people around
259here :)
260
261The name of the textfile is the hex encoded md5 sum of the selection, so
262the same content should lead to the same filename.
263
264After a successful upload the selection will be replaced by the text given
265in the C<selection-pastebin-url> resource (again, the % is the placeholder
266for the filename):

356
357=item $term = new urxvt [arg...]
358
359Creates a new terminal, very similar as if you had started it with
360C<system $binfile, arg...>. Croaks (and probably outputs an error message)
361if the new instance couldn't be created. Returns C<undef> if the new
362instance didn't initialise perl, and the terminal object otherwise. The
363C<init> and C<start> hooks will be called during the call.
364
365=item urxvt::fatal $errormessage
366
367Fatally aborts execution with the given error message. Avoid at all
368costs! The only time this is acceptable is when the terminal process
369starts up.
370
371=item urxvt::warn $string
372
373Calls C<rxvt_warn> with the given string which should not include a
374newline. The module also overwrites the C<warn> builtin with a function
375that calls this function.
376
377Using this function has the advantage that its output ends up in the
378correct place, e.g. on stderr of the connecting urxvtc client.
379
380=item $is_safe = urxvt::safe

580
581=item $urxvt::LIBDIR
582
583The rxvt-unicode library directory, where, among other things, the perl
584modules and scripts are stored.
585
586=item $urxvt::RESCLASS, $urxvt::RESCLASS
587
588The resource class and name rxvt-unicode uses to look up X resources.
589
590=item $urxvt::RXVTNAME
591
592The basename of the installed binaries, usually C<urxvt>.
593
594=item $urxvt::TERM
595
596The current terminal. This variable stores the current C<urxvt::term>
597object, whenever a callback/hook is executing.
598
599=item @urxvt::TERM_INIT
600
601All coderefs in this array will be called as methods of the next newly
602created C<urxvt::term> object (during the C<on_init> phase). The array
603gets cleared before the codereferences that were in it are being executed,
604so coderefs can push themselves onto it again if they so desire.
605
606This complements to the perl-eval commandline option, but gets executed
607first.
608
609=item @urxvt::TERM_EXT
610
611Works similar to C<@TERM_INIT>, but contains perl package/class names, which
612get registered as normal extensions after calling the hooks in C<@TERM_INIT>
613but before other extensions. Gets cleared just like C<@TERM_INIT>.

622
623Fatally aborts execution with the given error message. Avoid at all
624costs! The only time this is acceptable is when the terminal process
625starts up.
626
627=item urxvt::warn $string
628
629Calls C<rxvt_warn> with the given string which should not include a
630newline. The module also overwrites the C<warn> builtin with a function
631that calls this function.
632
633Using this function has the advantage that its output ends up in the
634correct place, e.g. on stderr of the connecting urxvtc client.
635
636Messages have a size limit of 1023 bytes currently.
637

669
670Rendition bitsets contain information about colour, font, font styles and
671similar information for each screen cell.
672
673The following "macros" deal with changes in rendition sets. You should
674never just create a bitset, you should always modify an existing one,
675as they contain important information required for correct operation of
676rxvt-unicode.

679
680=item $rend = urxvt::DEFAULT_RSTYLE
681
