38 selection (enabled by default)
39 (More) intelligent selection. This extension tries to be more
36 when the user extends selections (double-click). Right now, it tries 40 intelligent when the user extends selections (double-click and
37 to select urls and complete shell-quoted arguments, which is very 41 further clicks). Right now, it tries to select words, urls and
42 complete shell-quoted arguments, which is very convenient, too, if
38 convenient, too, if your ls supports "--quoting-style=shell". 43 your ls supports "--quoting-style=shell".
39 44
40 It also offers the following bindable event: 45 A double-click usually selects the word under the cursor, further
46 clicks will enlarge the selection.
47
48 The selection works by trying to match a number of regexes and
49 displaying them in increasing order of length. You can add your own
50 regexes by specifying resources of the form:
51
52 URxvt.selection.pattern-0: perl-regex
53 URxvt.selection.pattern-1: perl-regex
54 ...
55
56 The index number (0, 1...) must not have any holes, and each regex
57 must contain at least one pair of capturing parentheses, which will
58 be used for the match. For example, the followign adds a regex that
59 matches everything between two vertical bars:
60
61 URxvt.selection.pattern-0: \\|([^|]+)\\|
62
63 You can look at the source of the selection extension to see more
64 interesting uses, such as parsing a line from beginning to end.
65
66 This extension also offers following bindable keyboard commands:
41 67
42 rot13 68 rot13
43 Rot-13 the selection when activated. Used via keyboard trigger: 69 Rot-13 the selection when activated. Used via keyboard trigger:

46 72
47 digital-clock 73 option-popup (enabled by default)
48 Displays a digital clock using the built-in overlay. 74 Binds a popup menu to Ctrl-Button2 that lets you toggle (some)
75 options at runtime.
76
77 selection-popup (enabled by default)
78 Binds a popup menu to Ctrl-Button3 that lets you convert the
79 selection text into various other formats/action (such as uri
80 unescaping, perl evaluation, web-browser starting etc.), depending
81 on content.
82
83 Other extensions can extend this popup menu by pushing a code
84 reference onto "@{ $term-"{selection_popup_hook} }>, that is called
85 whenever the popup is displayed.
86
87 It's sole argument is the popup menu, which can be modified. The
88 selection is in $_, which can be used to decide wether to add
89 something or not. It should either return nothing or a string and a
90 code reference. The string will be used as button text and the code
91 reference will be called when the button gets activated and should
92 transform $_.
93
94 The following will add an entry "a to b" that transforms all "a"s in
95 the selection to "b"s, but only if the selection currently contains
96 any "a"s:
97
98 push @{ $self->{term}{selection_popup_hook} }, sub {
99 /a/ ? ("a to be" => sub { s/a/b/g }
100 : ()
101 };
102
103 searchable-scrollback<hotkey> (enabled by default)
104 Adds regex search functionality to the scrollback buffer, triggered
105 by a hotkey (default: "M-s"). While in search mode, normal terminal
106 input/output is suspended and a regex is displayed at the bottom of
107 the screen.
108
109 Inputting characters appends them to the regex and continues
110 incremental search. "BackSpace" removes a character from the regex,
111 "Up" and "Down" search upwards/downwards in the scrollback buffer,
112 "End" jumps to the bottom. "Escape" leaves search mode and returns
113 to the point where search was started, while "Enter" or "Return"
114 stay at the current position and additionally stores the first match
115 in the current line into the primary selection.
116
117 readline (enabled by default)
118 A support package that tries to make editing with readline easier.
119 At the moment, it reacts to clicking with the left mouse button by
120 trying to move the text cursor to this position. It does so by
121 generating as many cursor-left or cursor-right keypresses as
122 required (the this only works for programs that correctly support
123 wide characters).
124
125 To avoid too many false positives, this is only done when:
126
127 - the tty is in ICANON state.
128 - the text cursor is visible.
129 - the primary screen is currently being displayed.
130 - the mouse is on the same (multi-row-) line as the text cursor.
131
132 The normal selection mechanism isn't disabled, so quick successive
133 clicks might interfere with selection creation in harmless ways.
134
135 selection-autotransform
136 This selection allows you to do automatic transforms on a selection
137 whenever a selection is made.
138
139 It works by specifying perl snippets (most useful is a single "s///"
140 operator) that modify $_ as resources:
141
142 URxvt.selection-autotransform.0: transform
143 URxvt.selection-autotransform.1: transform
144 ...
145
146 For example, the following will transform selections of the form
147 "filename:number", often seen in compiler messages, into "vi
148 +$filename $word":
149
150 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
151
152 And this example matches the same,but replaces it with vi-commands
153 you can paste directly into your (vi :) editor:
154
155 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
156
157 Of course, this can be modified to suit your needs and your editor
158 :)
159
160 To expand the example above to typical perl error messages ("XXX at
161 FILENAME line YYY."), you need a slightly more elaborate solution:
162
163 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
164 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
165
166 The first line tells the selection code to treat the unchanging part
167 of every error message as a selection pattern, and the second line
168 transforms the message into vi commands to load the file.
169
170 tabbed
171 This transforms the terminal into a tabbar with additional
172 terminals, that is, it implements what is commonly refered to as
173 "tabbed terminal". The topmost line displays a "[NEW]" button,
174 which, when clicked, will add a new tab, followed by one button per
175 tab.
176
177 Clicking a button will activate that tab. Pressing Shift-Left and
178 Shift-Right will switch to the tab left or right of the current one,
179 while Shift-Down creates a new tab.
49 180
50 mark-urls 181 mark-urls
51 Uses per-line display filtering ("on_line_update") to underline 182 Uses per-line display filtering ("on_line_update") to underline urls
52 urls. 183 and make them clickable. When middle-clicked, the program specified
184 in the resource "urlLauncher" (default "x-www-browser") will be
185 started with the URL as first argument.
186
187 automove-background
188 This is basically a one-line extension that dynamically changes the
189 background pixmap offset to the window position, in effect creating
190 the same effect as pseudo transparency with a custom pixmap. No
191 scaling is supported in this mode. Exmaple:
192
193 rxvt -pixmap background.xpm -pe automove-background
53 194
54 block-graphics-to-ascii 195 block-graphics-to-ascii

56 terminal, by replacing all line-drawing characters (U+2500 .. 197 terminal, by replacing all line-drawing characters (U+2500 ..
57 U+259F) by a similar-looking ascii character. 198 U+259F) by a similar-looking ascii character.

62 your own overlays or changes. 206 your own overlays or changes.
63 207
208 selection-pastebin
209 This is a little rarely useful extension that Uploads the selection
210 as textfile to a remote site (or does other things). (The
211 implementation is not currently secure for use in a multiuser
212 environment as it writes to /tmp directly.).
213
214 It listens to the "selection-pastebin:remote-pastebin" keyboard
215 command, i.e.
216
217 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
218
219 Pressing this combination runs a command with "%" replaced by the
220 name of the textfile. This command can be set via a resource:
221
222 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
223
224 And the default is likely not useful to anybody but the few people
225 around here :)
226
227 The name of the textfile is the hex encoded md5 sum of the
228 selection, so the same content should lead to the same filename.
229
230 After a successful upload the selection will be replaced by the text
231 given in the "selection-pastebin-url" resource (again, the % is the
232 placeholder for the filename):
233
234 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

266 Extension Objects
267 Very perl extension is a perl class. A separate perl object is created
268 for each terminal and each extension and passed as the first parameter
269 to hooks. So extensions can use their $self object without having to
270 think about other extensions, with the exception of methods and members
271 that begin with an underscore character "_": these are reserved for
272 internal use.
273
274 Although it isn't a "urxvt::term" object, you can call all methods of
275 the "urxvt::term" class on this object.
276
277 It has the following methods and data members:
278
279 $urxvt_term = $self->{term}
280 Returns the "urxvt::term" object associated with this instance of
281 the extension. This member *must not* be changed in any way.
282
283 $self->enable ($hook_name => $cb, [$hook_name => $cb..])
284 Dynamically enable the given hooks (named without the "on_" prefix)
285 for this extension, replacing any previous hook. This is useful when
286 you want to overwrite time-critical hooks only temporarily.
287
288 $self->disable ($hook_name[, $hook_name..])
289 Dynamically disable the given hooks.

246 484
485 @urxvt::TERM_INIT
486 All coderefs in this array will be called as methods of the next
487 newly created "urxvt::term" object (during the "on_init" phase). The
488 array gets cleared before the codereferences that were in it are
489 being executed, so coderefs can push themselves onto it again if
490 they so desire.
491
492 This complements to the perl-eval commandline option, but gets
493 executed first.
494
495 @urxvt::TERM_EXT
496 Works similar to @TERM_INIT, but contains perl package/class names,
497 which get registered as normal extensions after calling the hooks in
498 @TERM_INIT but before other extensions. Gets cleared just like
499 @TERM_INIT.

247 Functions in the "urxvt" Package 501 Functions in the "urxvt" Package
248 $term = new urxvt [arg...]
249 Creates a new terminal, very similar as if you had started it with
250 "system $binfile, arg...". Croaks (and probably outputs an error
251 message) if the new instance couldn't be created. Returns "undef" if
252 the new instance didn't initialise perl, and the terminal object
253 otherwise. The "init" and "start" hooks will be called during the
254 call.

310 579
580 The "urxvt::anyevent" Class
581 The sole purpose of this class is to deliver an interface to the
582 "AnyEvent" module - any module using it will work inside urxvt without
583 further programming. The only exception is that you cannot wait on
584 condition variables, but non-blocking condvar use is ok. What this means
585 is that you cannot use blocking APIs, but the non-blocking variant
586 should work.
587
311 The "urxvt::term" Class 588 The "urxvt::term" Class
589 $term = new urxvt::term $envhashref, $rxvtname, [arg...]

591 system "$rxvtname, arg...". $envhashref must be a reference to a
592 %ENV-like hash which defines the environment of the new terminal.
593
594 Croaks (and probably outputs an error message) if the new instance
595 couldn't be created. Returns "undef" if the new instance didn't
596 initialise perl, and the terminal object otherwise. The "init" and
597 "start" hooks will be called during this call.

313 Destroy the terminal object (close the window, free resources etc.). 600 Destroy the terminal object (close the window, free resources etc.).
601 Please note that rxvt will not exit as long as any event watchers
602 (timers, io watchers) are still active.
603
604 $term->exec_async ($cmd[, @args])
605 Works like the combination of the "fork"/"exec" builtins, which
606 executes ("starts") programs in the background. This function takes
607 care of setting the user environment before exec'ing the command
608 (e.g. "PATH") and should be preferred over explicit calls to "exec"
609 or "system".
610
611 Returns the pid of the subprocess or "undef" on error.
612
613 $isset = $term->option ($optval[, $set])
614 Returns true if the option specified by $optval is enabled, and
615 optionally change it. All option values are stored by name in the
616 hash %urxvt::OPTION. Options not enabled in this binary are not in
617 the hash.
