35 Intelligent selection. This extension tries to be more intelligent 35 (More) intelligent selection. This extension tries to be more
36 when the user extends selections (double-click). Right now, it tries 36 intelligent when the user extends selections (double-click and
37 to select urls and complete shell-quoted arguments, which is very 37 further clicks). Right now, it tries to select words, urls and
38 complete shell-quoted arguments, which is very convenient, too, if
38 convenient, too, if your ls supports "--quoting-style=shell". 39 your ls supports "--quoting-style=shell".
39 40
40 It also offers the following bindable event: 41 A double-click usually selects the word under the cursor, further
42 clicks will enlarge the selection.
43
44 The selection works by trying to match a number of regexes and
45 displaying them in increasing order of length. You can add your own
46 regexes by specifying resources of the form:
47
48 URxvt.selection.pattern-0: perl-regex
49 URxvt.selection.pattern-1: perl-regex
50 ...
51
52 The index number (0, 1...) must not have any holes, and each regex
53 must contain at least one pair of capturing parentheses, which will
54 be used for the match. For example, the followign adds a regex that
55 matches everything between two vertical bars:
56
57 URxvt.selection.pattern-0: \\|([^|]+)\\|
58
59 You can look at the source of the selection extension to see more
60 interesting uses, such as parsing a line from beginning to end.
61
62 This extension also offers following bindable keyboard commands:
41 63
42 rot13 64 rot13
43 Rot-13 the selection when activated. Used via keyboard trigger: 65 Rot-13 the selection when activated. Used via keyboard trigger:
44 66
45 URxvt.keysym.C-M-r: perl:selection:rot13 67 URxvt.keysym.C-M-r: perl:selection:rot13
68
69 option-popup (enabled by default)
70 Binds a popup menu to Ctrl-Button2 that lets you toggle (some)
71 options at runtime.
72
73 selection-popup (enabled by default)
74 Binds a popup menu to Ctrl-Button3 that lets you convert the
75 selection text into various other formats/action (such as uri
76 unescaping, perl evalution, web-browser starting etc.), depending on
77 content.
78
79 Other extensions can extend this popup menu by pushing a code
80 reference onto "@{ $term-"{selection_popup_hook} }>, that is called
81 whenever the popup is displayed.
82
83 It's sole argument is the popup menu, which can be modified. The
84 selection is in $_, which can be used to decide wether to add
85 something or not. It should either return nothing or a string and a
86 code reference. The string will be used as button text and the code
87 reference will be called when the button gets activated and should
88 transform $_.
89
90 The following will add an entry "a to b" that transforms all "a"s in
91 the selection to "b"s, but only if the selection currently contains
92 any "a"s:
93
94 push @{ $self->{term}{selection_popup_hook} }, sub {
95 /a/ ? ("a to be" => sub { s/a/b/g }
96 : ()
97 };
98
99 searchable-scrollback<hotkey> (enabled by default)
100 Adds regex search functionality to the scrollback buffer, triggered
101 by a hotkey (default: "M-s"). While in search mode, normal terminal
102 input/output is suspended and a regex is displayed at the bottom of
103 the screen.
104
105 Inputting characters appends them to the regex and continues
106 incremental search. "BackSpace" removes a character from the regex,
107 "Up" and "Down" search upwards/downwards in the scrollback buffer,
108 "End" jumps to the bottom. "Escape" leaves search mode and returns
109 to the point where search was started, while "Enter" or "Return"
110 stay at the current position and additionally stores the first match
111 in the current line into the primary selection.
112
113 selection-autotransform
114 This selection allows you to do automatic transforms on a selection
115 whenever a selection is made.
116
117 It works by specifying perl snippets (most useful is a single "s///"
118 operator) that modify $_ as resources:
119
120 URxvt.selection-autotransform.0: transform
121 URxvt.selection-autotransform.1: transform
122 ...
123
124 For example, the following will transform selections of the form
125 "filename:number", often seen in compiler messages, into "vi
126 +$filename $word":
127
128 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
129
130 And this example matches the same,but replaces it with vi-commands
131 you can paste directly into your (vi :) editor:
132
133 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
134
135 Of course, this can be modified to suit your needs and your editor
136 :)
137
138 To expand the example above to typical perl error messages ("XXX at
139 FILENAME line YYY."), you need a slightly more elaborate solution:
140
141 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
142 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
143
144 The first line tells the selection code to treat the unchanging part
145 of every error message as a selection pattern, and the second line
146 transforms the message into vi commands to load the file.
147
148 mark-urls
149 Uses per-line display filtering ("on_line_update") to underline urls
150 and make them clickable. When middle-clicked, the program specified
151 in the resource "urlLauncher" (default "x-www-browser") will be
152 started with the URL as first argument.
153
154 automove-background
155 This is basically a one-line extension that dynamically changes the
156 background pixmap offset to the window position, in effect creating
157 the same effect as pseudo transparency with a custom pixmap. No
158 scaling is supported in this mode. Exmaple:
159
160 rxvt -pixmap background.xpm -pe automove-background
161
162 block-graphics-to-ascii
163 A not very useful example of filtering all text output to the
164 terminal, by replacing all line-drawing characters (U+2500 ..
165 U+259F) by a similar-looking ascii character.
46 166
47 digital-clock 167 digital-clock
48 Displays a digital clock using the built-in overlay. 168 Displays a digital clock using the built-in overlay.

52 the window. Illustrates overwriting the refresh callbacks to create 172 the window. Illustrates overwriting the refresh callbacks to create
53 your own overlays or changes. 173 your own overlays or changes.
54 174
175 selection-pastebin
176 This is a little rarely useful extension that Uploads the selection
177 as textfile to a remote site (or does other things). (The
178 implementation is not currently secure for use in a multiuser
179 environment as it writes to /tmp directly.).
180
181 It listens to the "selection-pastebin:remote-pastebin" keyboard
182 command, i.e.
183
184 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
185
186 Pressing this combination runs a command with "%" replaced by the
187 name of the textfile. This command can be set via a resource:
188
189 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
190
191 And the default is likely not useful to anybody but the few people
192 around here :)
193
194 The name of the textfile is the hex encoded md5 sum of the
195 selection, so the same content should lead to the same filename.
196
197 After a successful upload the selection will be replaced by the text
198 given in the "selection-pastebin-url" resource (again, the % is the
199 placeholder for the filename):
200
201 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

66 215
216 Argument names also often indicate the type of a parameter. Here are
217 some hints on what they mean:
218
219 $text
220 Rxvt-unicodes special way of encoding text, where one "unicode"
221 character always represents one screen cell. See ROW_t for a
222 discussion of this format.
223
224 $string
225 A perl text string, with an emphasis on *text*. It can store all
226 unicode characters and is to be distinguished with text encoded in a
227 specific encoding (often locale-specific) and binary data.
228
229 $octets
230 Either binary data or - more common - a text string encoded in a
231 locale-specific way.
232
233 Extension Objects
234 Very perl extension is a perl class. A separate perl object is created
235 for each terminal and each extension and passed as the first parameter
236 to hooks. So extensions can use their $self object without having to
237 think about other extensions, with the exception of methods and members
238 that begin with an underscore character "_": these are reserved for
239 internal use.
240
241 Although it isn't a "urxvt::term" object, you can call all methods of
242 the "urxvt::term" class on this object.
243
244 It has the following methods and data members:
245
246 $urxvt_term = $self->{term}
247 Returns the "urxvt::term" object associated with this instance of
248 the extension. This member *must not* be changed in any way.
249
250 $self->enable ($hook_name => $cb, [$hook_name => $cb..])
251 Dynamically enable the given hooks (named without the "on_" prefix)
252 for this extension, replacing any previous hook. This is useful when
253 you want to overwrite time-critical hooks only temporarily.
254
255 $self->disable ($hook_name[, $hook_name..])
256 Dynamically disable the given hooks.
257

73 its not a real "urxvt::term" object. Instead, the real "urxvt::term"
74 object that is shared between all packages is stored in the "term"
75 member.

159 348
349 on_add_lines $term, $string
350 Called whenever text is about to be output, with the text as
351 argument. You can filter/change and output the text yourself by
352 returning a true value and calling "$term->scr_add_lines" yourself.
353 Please note that this might be very slow, however, as your hook is
354 called for all text being output.
355
356 on_tt_write $term, $octets
357 Called whenever some data is written to the tty/pty and can be used
358 to suppress or filter tty input.
359
360 on_line_update $term, $row
361 Called whenever a line was updated or changed. Can be used to filter
362 screen output (e.g. underline urls or other useless stuff). Only
363 lines that are being shown will be filtered, and, due to performance
364 reasons, not always immediately.
365
366 The row number is always the topmost row of the line if the line
367 spans multiple rows.
368
369 Please note that, if you change the line, then the hook might get
370 called later with the already-modified line (e.g. if unrelated parts
371 change), so you cannot just toggle rendition bits, but only set
372 them.
373
160 on_refresh_begin $term 374 on_refresh_begin $term
161 Called just before the screen gets redrawn. Can be used for overlay 375 Called just before the screen gets redrawn. Can be used for overlay

172 resource in the rxvt(1) manpage). 386 resource in the rxvt(1) manpage).
173 387
388 on_x_event $term, $event
389 Called on every X event received on the vt window (and possibly
390 other windows). Should only be used as a last resort. Most event
391 structure members are not passed.
392
393 on_focus_in $term
394 Called whenever the window gets the keyboard focus, before
395 rxvt-unicode does focus in processing.
396
397 on_focus_out $term
398 Called wheneever the window loses keyboard focus, before
399 rxvt-unicode does focus out processing.

407 on_map_notify $term, $event
408 on_unmap_notify $term, $event
409 Called whenever the corresponding X event is received for the
410 terminal If the hook returns true, then the even will be ignored by
411 rxvt-unicode.
412
413 The event is a hash with most values as named by Xlib (see the
414 XEvent manpage), with the additional members "row" and "col", which
415 are the row and column under the mouse cursor.

517 The "urxvt::anyevent" Class
518 The sole purpose of this class is to deliver an interface to the
519 "AnyEvent" module - any module using it will work inside urxvt without
520 further programming. The only exception is that you cannot wait on
521 condition variables, but non-blocking condvar use is ok. What this means
522 is that you cannot use blocking APIs, but the non-blocking variant
523 should work.
524
235 The "urxvt::term" Class 525 The "urxvt::term" Class
526 $term = new urxvt::term $envhashref, $rxvtname, [arg...]
527 Creates a new terminal, very similar as if you had started it with
528 system "$rxvtname, arg...". $envhashref must be a reference to a
529 %ENV-like hash which defines the environment of the new terminal.
530
531 Croaks (and probably outputs an error message) if the new instance
532 couldn't be created. Returns "undef" if the new instance didn't
533 initialise perl, and the terminal object otherwise. The "init" and
534 "start" hooks will be called during this call.
535
536 $term->destroy
537 Destroy the terminal object (close the window, free resources etc.).
538 Please note that rxvt will not exit as long as any event watchers
539 (timers, io watchers) are still active.
540
541 $term->exec_async ($cmd[, @args])
542 Works like the combination of the "fork"/"exec" builtins, which
543 executes ("starts") programs in the background. This function takes
544 care of setting the user environment before exec'ing the command
545 (e.g. "PATH") and should be preferred over explicit calls to "exec"
546 or "system".
547
548 Returns the pid of the subprocess or "undef" on error.
549
550 $isset = $term->option ($optval[, $set])
551 Returns true if the option specified by $optval is enabled, and

604 the same value as used by this instance of rxvt-unicode. Returns
605 "undef" if no resource with that pattern exists.
606
607 This method should only be called during the "on_start" hook, as
608 there is only one resource database per display, and later
609 invocations might return the wrong resources.
610
611 $success = $term->parse_keysym ($keysym_spec, $command_string)
612 Adds a keymap translation exactly as specified via a resource. See
613 the "keysym" resource in the rxvt(1) manpage.

618
619 ($row, $col) = $term->screen_cur ([$row, $col])
620 Return the current coordinates of the text cursor position and
621 optionally set it (which is usually bad as applications don't expect
622 that).

630 $term->selection_make ($eventtime[, $rectangular])
631 Tries to make a selection as set by "selection_beg" and
632 "selection_end". If $rectangular is true (default: false), a

698 $term->scr_xor_rect ($beg_row, $beg_col, $end_row, $end_col[, $rstyle1[,
699 $rstyle2]])
700 Similar to "scr_xor_span", but xors a rectangle instead. Trailing
701 whitespace will additionally be xored with the $rstyle2, which
702 defaults to "RS_RVid | RS_Uline", which removes reverse video again
703 and underlines it instead. Both styles *MUST NOT* contain font
704 styles.

707 Ring the bell!
708
709 $term->scr_add_lines ($string)
710 Write the given text string to the screen, as if output by the
711 application running inside the terminal. It may not contain command
712 sequences (escape codes), but is free to use line feeds, carriage
713 returns and tabs. The string is a normal text string, not in
714 locale-dependent encoding.
715
716 Normally its not a good idea to use this function, as programs might
717 be confused by changes in cursor position or scrolling. Its useful
718 inside a "on_add_lines" hook, though.
719
720 $term->cmd_parse ($octets)
721 Similar to "scr_add_lines", but the argument must be in the
722 locale-specific encoding of the terminal and can contain command
723 sequences (escape codes) that will be interpreted.

341 strings first to the locale-specific encoding using 728 strings first to the locale-specific encoding using
342 "$term->locale_encode". 729 "$term->locale_encode".
343 730
