35 Intelligent selection. This extension tries to be more intelligent 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 Another example: Programs I use often output "absolute path: " at
64 the beginning of a line when they process multiple files. The
65 following pattern matches the filename (note, there is a single
66 space at the very end):
67
68 URxvt.selection.pattern-0: ^(/[^:]+):\
69
70 You can look at the source of the selection extension to see more
71 interesting uses, such as parsing a line from beginning to end.
72
73 This extension also offers following bindable keyboard commands:
41 74

46 79
47 option-popup (enabled by default) 80 option-popup (enabled by default)
48 Binds a popup menu to Ctrl-Button3 that lets you toggle (some) 81 Binds a popup menu to Ctrl-Button2 that lets you toggle (some)
49 options at runtime. 82 options at runtime.
50 83
51 digital-clock 84 selection-popup (enabled by default)
52 Displays a digital clock using the built-in overlay. 85 Binds a popup menu to Ctrl-Button3 that lets you convert the
86 selection text into various other formats/action (such as uri
87 unescaping, perl evaluation, web-browser starting etc.), depending
88 on content.
89
90 Other extensions can extend this popup menu by pushing a code
91 reference onto "@{ $term-"{selection_popup_hook} }>, that is called
92 whenever the popup is displayed.
93
94 It's sole argument is the popup menu, which can be modified. The
95 selection is in $_, which can be used to decide wether to add
96 something or not. It should either return nothing or a string and a
97 code reference. The string will be used as button text and the code
98 reference will be called when the button gets activated and should
99 transform $_.
100
101 The following will add an entry "a to b" that transforms all "a"s in
102 the selection to "b"s, but only if the selection currently contains
103 any "a"s:
104
105 push @{ $self->{term}{selection_popup_hook} }, sub {
106 /a/ ? ("a to be" => sub { s/a/b/g }
107 : ()
108 };
109
110 searchable-scrollback<hotkey> (enabled by default)
111 Adds regex search functionality to the scrollback buffer, triggered
112 by a hotkey (default: "M-s"). While in search mode, normal terminal
113 input/output is suspended and a regex is displayed at the bottom of
114 the screen.
115
116 Inputting characters appends them to the regex and continues
117 incremental search. "BackSpace" removes a character from the regex,
118 "Up" and "Down" search upwards/downwards in the scrollback buffer,
119 "End" jumps to the bottom. "Escape" leaves search mode and returns
120 to the point where search was started, while "Enter" or "Return"
121 stay at the current position and additionally stores the first match
122 in the current line into the primary selection.
123
124 readline (enabled by default)
125 A support package that tries to make editing with readline easier.
126 At the moment, it reacts to clicking with the left mouse button by
127 trying to move the text cursor to this position. It does so by
128 generating as many cursor-left or cursor-right keypresses as
129 required (the this only works for programs that correctly support
130 wide characters).
131
132 To avoid too many false positives, this is only done when:
133
134 - the tty is in ICANON state.
135 - the text cursor is visible.
136 - the primary screen is currently being displayed.
137 - the mouse is on the same (multi-row-) line as the text cursor.
138
139 The normal selection mechanism isn't disabled, so quick successive
140 clicks might interfere with selection creation in harmless ways.
141
142 selection-autotransform
143 This selection allows you to do automatic transforms on a selection
144 whenever a selection is made.
145
146 It works by specifying perl snippets (most useful is a single "s///"
147 operator) that modify $_ as resources:
148
149 URxvt.selection-autotransform.0: transform
150 URxvt.selection-autotransform.1: transform
151 ...
152
153 For example, the following will transform selections of the form
154 "filename:number", often seen in compiler messages, into "vi
155 +$filename $word":
156
157 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
158
159 And this example matches the same,but replaces it with vi-commands
160 you can paste directly into your (vi :) editor:
161
162 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
163
164 Of course, this can be modified to suit your needs and your editor
165 :)
166
167 To expand the example above to typical perl error messages ("XXX at
168 FILENAME line YYY."), you need a slightly more elaborate solution:
169
170 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
171 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
172
173 The first line tells the selection code to treat the unchanging part
174 of every error message as a selection pattern, and the second line
175 transforms the message into vi commands to load the file.
176
177 tabbed
178 This transforms the terminal into a tabbar with additional
179 terminals, that is, it implements what is commonly refered to as
180 "tabbed terminal". The topmost line displays a "[NEW]" button,
181 which, when clicked, will add a new tab, followed by one button per
182 tab.
183
184 Clicking a button will activate that tab. Pressing Shift-Left and
185 Shift-Right will switch to the tab left or right of the current one,
186 while Shift-Down creates a new tab.
187
188 The tabbar itself can be configured similarly to a normal terminal,
189 but with a resource class of "URxvt.tabbed". In addition, it
190 supports the following four resources (shown with defaults):
191
192 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
193 URxvt.tabbed.tabbar-bg: <colour-index, default 0>
194 URxvt.tabbed.tab-fg: <colour-index, default 0>
195 URxvt.tabbed.tab-bg: <colour-index, default 1>
196
197 See *COLOR AND GRAPHICS* in the rxvt(1) manpage for valid indices.

56 urls. 201 and make them clickable. When middle-clicked, the program specified
202 in the resource "urlLauncher" (default "x-www-browser") will be
203 started with the URL as first argument.
204
205 xim-onthespot
206 This (experimental) perl extension implements OnTheSpot editing. It
207 does not work perfectly, and some input methods don't seem to work
208 well with OnTheSpot editing in general, but it seems to work at
209 leats for SCIM and kinput2.
210
211 You enable it by specifying this extension and a preedit style of
212 "OnTheSpot", i.e.:
213
214 rxvt -pt OnTheSpot -pe xim-onthespot
215
216 automove-background
217 This is basically a one-line extension that dynamically changes the
218 background pixmap offset to the window position, in effect creating
219 the same effect as pseudo transparency with a custom pixmap. No
220 scaling is supported in this mode. Exmaple:
221
222 rxvt -pixmap background.xpm -pe automove-background

61 U+259F) by a similar-looking ascii character. 227 U+259F) by a similar-looking ascii character.
62 228
229 digital-clock
230 Displays a digital clock using the built-in overlay.
231
232 remote-clipboard
233 Somewhat of a misnomer, this extension adds two menu entries to the
234 selection popup that allows one ti run external commands to store
235 the selection somewhere and fetch it again.
236
237 We use it to implement a "distributed selection mechanism", which
238 just means that one command uploads the file to a remote server, and
239 another reads it.
240
241 The commands can be set using the "URxvt.remote-selection.store" and
242 "URxvt.remote-selection.fetch" resources. The first should read the
243 selection to store from STDIN (always in UTF-8), the second should
244 provide the selection data on STDOUT (also in UTF-8).
245
246 The defaults (which are likely useless to you) use rsh and cat:
247
248 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
249 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
250
251 selection-pastebin
252 This is a little rarely useful extension that Uploads the selection
253 as textfile to a remote site (or does other things). (The
254 implementation is not currently secure for use in a multiuser
255 environment as it writes to /tmp directly.).
256
257 It listens to the "selection-pastebin:remote-pastebin" keyboard
258 command, i.e.
259
260 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
261
262 Pressing this combination runs a command with "%" replaced by the
263 name of the textfile. This command can be set via a resource:
264
265 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
266
267 And the default is likely not useful to anybody but the few people
268 around here :)
269
270 The name of the textfile is the hex encoded md5 sum of the
271 selection, so the same content should lead to the same filename.
272
273 After a successful upload the selection will be replaced by the text
274 given in the "selection-pastebin-url" resource (again, the % is the
275 placeholder for the filename):
276
277 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

314 Extension Objects
315 Very perl extension is a perl class. A separate perl object is created
316 for each terminal and each extension and passed as the first parameter
317 to hooks. So extensions can use their $self object without having to
318 think about other extensions, with the exception of methods and members
319 that begin with an underscore character "_": these are reserved for
320 internal use.
321
322 Although it isn't a "urxvt::term" object, you can call all methods of
323 the "urxvt::term" class on this object.
324
325 It has the following methods and data members:
326
327 $urxvt_term = $self->{term}
328 Returns the "urxvt::term" object associated with this instance of
329 the extension. This member *must not* be changed in any way.
330
331 $self->enable ($hook_name => $cb, [$hook_name => $cb..])
332 Dynamically enable the given hooks (named without the "on_" prefix)
333 for this extension, replacing any previous hook. This is useful when
334 you want to overwrite time-critical hooks only temporarily.
335
336 $self->disable ($hook_name[, $hook_name..])
337 Dynamically disable the given hooks.

535 @urxvt::TERM_INIT
536 All coderefs in this array will be called as methods of the next
537 newly created "urxvt::term" object (during the "on_init" phase). The
538 array gets cleared before the codereferences that were in it are
539 being executed, so coderefs can push themselves onto it again if
540 they so desire.
541
542 This complements to the perl-eval commandline option, but gets
543 executed first.
544
545 @urxvt::TERM_EXT
546 Works similar to @TERM_INIT, but contains perl package/class names,
547 which get registered as normal extensions after calling the hooks in
548 @TERM_INIT but before other extensions. Gets cleared just like
