42 clicks will enlarge the selection. 46 clicks will enlarge the selection.
43 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: ^(/[^:]+):\

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.

75 digital-clock 141 readline (enabled by default)
76 Displays a digital clock using the built-in overlay. 142 A support package that tries to make editing with readline easier.
143 At the moment, it reacts to clicking shift-left mouse button by
144 trying to move the text cursor to this position. It does so by
145 generating as many cursor-left or cursor-right keypresses as
146 required (the this only works for programs that correctly support
147 wide characters).
148
149 To avoid too many false positives, this is only done when:
150
151 - the tty is in ICANON state.
152 - the text cursor is visible.
153 - the primary screen is currently being displayed.
154 - the mouse is on the same (multi-row-) line as the text cursor.
155
156 The normal selection mechanism isn't disabled, so quick successive
157 clicks might interfere with selection creation in harmless ways.
158
159 selection-autotransform
160 This selection allows you to do automatic transforms on a selection
161 whenever a selection is made.
162
163 It works by specifying perl snippets (most useful is a single "s///"
164 operator) that modify $_ as resources:
165
166 URxvt.selection-autotransform.0: transform
167 URxvt.selection-autotransform.1: transform
168 ...
169
170 For example, the following will transform selections of the form
171 "filename:number", often seen in compiler messages, into "vi
172 +$filename $word":
173
174 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
175
176 And this example matches the same,but replaces it with vi-commands
177 you can paste directly into your (vi :) editor:
178
179 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
180
181 Of course, this can be modified to suit your needs and your editor
182 :)
183
184 To expand the example above to typical perl error messages ("XXX at
185 FILENAME line YYY."), you need a slightly more elaborate solution:
186
187 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
188 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
189
190 The first line tells the selection code to treat the unchanging part
191 of every error message as a selection pattern, and the second line
192 transforms the message into vi commands to load the file.
193
194 tabbed
195 This transforms the terminal into a tabbar with additional
196 terminals, that is, it implements what is commonly refered to as
197 "tabbed terminal". The topmost line displays a "[NEW]" button,
198 which, when clicked, will add a new tab, followed by one button per
199 tab.
200
201 Clicking a button will activate that tab. Pressing Shift-Left and
202 Shift-Right will switch to the tab left or right of the current one,
203 while Shift-Down creates a new tab.
204
205 The tabbar itself can be configured similarly to a normal terminal,
206 but with a resource class of "URxvt.tabbed". In addition, it
207 supports the following four resources (shown with defaults):
208
209 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
210 URxvt.tabbed.tabbar-bg: <colour-index, default 0>
211 URxvt.tabbed.tab-fg: <colour-index, default 0>
212 URxvt.tabbed.tab-bg: <colour-index, default 1>
213
214 See *COLOR AND GRAPHICS* in the rxvt(1) manpage for valid indices.

83 221
222 xim-onthespot
223 This (experimental) perl extension implements OnTheSpot editing. It
224 does not work perfectly, and some input methods don't seem to work
225 well with OnTheSpot editing in general, but it seems to work at
226 leats for SCIM and kinput2.
227
228 You enable it by specifying this extension and a preedit style of
229 "OnTheSpot", i.e.:
230
231 rxvt -pt OnTheSpot -pe xim-onthespot
232
233 automove-background
234 This is basically a one-line extension that dynamically changes the
235 background pixmap offset to the window position, in effect creating
236 the same effect as pseudo transparency with a custom pixmap. No
237 scaling is supported in this mode. Exmaple:
238
239 rxvt -pixmap background.xpm -pe automove-background

87 U+259F) by a similar-looking ascii character. 244 U+259F) by a similar-looking ascii character.
245
246 digital-clock
247 Displays a digital clock using the built-in overlay.
248
249 remote-clipboard
250 Somewhat of a misnomer, this extension adds two menu entries to the
251 selection popup that allows one ti run external commands to store
252 the selection somewhere and fetch it again.
253
254 We use it to implement a "distributed selection mechanism", which
255 just means that one command uploads the file to a remote server, and
256 another reads it.
257
258 The commands can be set using the "URxvt.remote-selection.store" and
259 "URxvt.remote-selection.fetch" resources. The first should read the
260 selection to store from STDIN (always in UTF-8), the second should
261 provide the selection data on STDOUT (also in UTF-8).
262
263 The defaults (which are likely useless to you) use rsh and cat:
264
265 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
266 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
267
268 selection-pastebin
269 This is a little rarely useful extension that Uploads the selection
270 as textfile to a remote site (or does other things). (The
271 implementation is not currently secure for use in a multiuser
272 environment as it writes to /tmp directly.).
273
274 It listens to the "selection-pastebin:remote-pastebin" keyboard
275 command, i.e.
276
277 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
278
279 Pressing this combination runs a command with "%" replaced by the
280 name of the textfile. This command can be set via a resource:
281
282 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
283
284 And the default is likely not useful to anybody but the few people
285 around here :)
286
287 The name of the textfile is the hex encoded md5 sum of the
288 selection, so the same content should lead to the same filename.
289
290 After a successful upload the selection will be replaced by the text
291 given in the "selection-pastebin-url" resource (again, the % is the
292 placeholder for the filename):
293
294 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
