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.

82This extension also offers following bindable keyboard commands:

80 155
81Displays a digital clock using the built-in overlay. 156The regex defaults to "(?i)", resulting in a case-insensitive search. To
157get a case-sensitive search you can delete this prefix using C<BackSpace>
158or simply use an uppercase character which removes the "(?i)" prefix.
159
160See L<perlre> for more info about perl regular expression syntax.
161
162=item readline (enabled by default)
163
164A support package that tries to make editing with readline easier. At
165the moment, it reacts to clicking shift-left mouse button by trying to
166move the text cursor to this position. It does so by generating as many
167cursor-left or cursor-right keypresses as required (the this only works
168for programs that correctly support wide characters).
169
170To avoid too many false positives, this is only done when:
171
172=over 4
173
174=item - the tty is in ICANON state.
175
176=item - the text cursor is visible.
177
178=item - the primary screen is currently being displayed.
179
180=item - the mouse is on the same (multi-row-) line as the text cursor.
181
182=back
183
184The normal selection mechanism isn't disabled, so quick successive clicks
185might interfere with selection creation in harmless ways.
186
187=item selection-autotransform
188
189This selection allows you to do automatic transforms on a selection
190whenever a selection is made.
191
192It works by specifying perl snippets (most useful is a single C<s///>
193operator) that modify C<$_> as resources:
194
195 URxvt.selection-autotransform.0: transform
196 URxvt.selection-autotransform.1: transform
197 ...
198
199For example, the following will transform selections of the form
200C<filename:number>, often seen in compiler messages, into C<vi +$filename
201$word>:
202
203 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
204
205And this example matches the same,but replaces it with vi-commands you can
206paste directly into your (vi :) editor:
207
208 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
209
210Of course, this can be modified to suit your needs and your editor :)
211
212To expand the example above to typical perl error messages ("XXX at
213FILENAME line YYY."), you need a slightly more elaborate solution:
214
215 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
216 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
217
218The first line tells the selection code to treat the unchanging part of
219every error message as a selection pattern, and the second line transforms
220the message into vi commands to load the file.
221
222=item tabbed
223
224This transforms the terminal into a tabbar with additional terminals, that
225is, it implements what is commonly refered to as "tabbed terminal". The topmost line
226displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
227button per tab.
228
229Clicking a button will activate that tab. Pressing B<Shift-Left> and
230B<Shift-Right> will switch to the tab left or right of the current one,
231while B<Shift-Down> creates a new tab.
232
233The tabbar itself can be configured similarly to a normal terminal, but
234with a resource class of C<URxvt.tabbed>. In addition, it supports the
235following four resources (shown with defaults):
236
237 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
238 URxvt.tabbed.tabbar-bg: <colour-index, default 0>
239 URxvt.tabbed.tab-fg: <colour-index, default 0>
240 URxvt.tabbed.tab-bg: <colour-index, default 1>
241
242See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
243indices.

85Uses per-line display filtering (C<on_line_update>) to underline urls. 247Uses per-line display filtering (C<on_line_update>) to underline urls and
248make them clickable. When middle-clicked, the program specified in the
249resource C<urlLauncher> (default C<x-www-browser>) will be started with
250the URL as first argument.
251
252=item xim-onthespot
253
254This (experimental) perl extension implements OnTheSpot editing. It does
255not work perfectly, and some input methods don't seem to work well with
256OnTheSpot editing in general, but it seems to work at leats for SCIM and
257kinput2.
258
259You enable it by specifying this extension and a preedit style of
260C<OnTheSpot>, i.e.:

264=item automove-background
265
266This is basically a very small extension that dynamically changes the
267background pixmap offset to the window position, in effect creating the
268same effect as pseudo transparency with a custom pixmap. No scaling is
269supported in this mode. Exmaple:

279=item digital-clock
280
281Displays a digital clock using the built-in overlay.
282
283=item remote-clipboard
284
285Somewhat of a misnomer, this extension adds two menu entries to the
286selection popup that allows one ti run external commands to store the
287selection somewhere and fetch it again.
288
289We use it to implement a "distributed selection mechanism", which just
290means that one command uploads the file to a remote server, and another
291reads it.
292
293The commands can be set using the C<URxvt.remote-selection.store> and
294C<URxvt.remote-selection.fetch> resources. The first should read the
295selection to store from STDIN (always in UTF-8), the second should provide
296the selection data on STDOUT (also in UTF-8).
297
298The defaults (which are likely useless to you) use rsh and cat:
299
300 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
301 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
302
303=item selection-pastebin
304
305This is a little rarely useful extension that Uploads the selection as
306textfile to a remote site (or does other things). (The implementation is
307not currently secure for use in a multiuser environment as it writes to
308F</tmp> directly.).
309
310It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
311i.e.
312
313 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
314
315Pressing this combination runs a command with C<%> replaced by the name of
316the textfile. This command can be set via a resource:
317
318 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
319
320And the default is likely not useful to anybody but the few people around
321here :)
322
323The name of the textfile is the hex encoded md5 sum of the selection, so
324the same content should lead to the same filename.
325
326After a successful upload the selection will be replaced by the text given
327in the C<selection-pastebin-url> resource (again, the % is the placeholder
328for 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
381
382Returns true when it is safe to do potentially unsafe things, such as
383evaluating perl code specified by the user. This is true when urxvt was
384started setuid or setgid.
385
386=item $time = urxvt::NOW

420
421=item $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
422
423Return the bit that enabled bold, italic, blink, reverse-video and
424underline, respectively. To enable such a style, just logically OR it into
425the bitset.
426
427=item $foreground = urxvt::GET_BASEFG $rend
428
429=item $background = urxvt::GET_BASEBG $rend

438specified one.
439
440=item $value = urxvt::GET_CUSTOM ($rend)
441
442Return the "custom" value: Every rendition has 5 bits for use by
443extensions. They can be set and changed as you like and are initially
444zero.
445

689gets cleared before the codereferences that were in it are being executed,
690so coderefs can push themselves onto it again if they so desire.
691
692This complements to the perl-eval commandline option, but gets executed
693first.
694
695=item @urxvt::TERM_EXT
696
697Works similar to C<@TERM_INIT>, but contains perl package/class names, which
698get registered as normal extensions after calling the hooks in C<@TERM_INIT>
699but before other extensions. Gets cleared just like C<@TERM_INIT>.
