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.

104
105Other extensions can extend this popup menu by pushing a code reference
106onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
107popup is displayed.
108
109It's sole argument is the popup menu, which can be modified. The selection
110is in C<$_>, which can be used to decide wether to add something or not.
111It should either return nothing or a string and a code reference. The
112string will be used as button text and the code reference will be called
113when the button gets activated and should transform C<$_>.
114
115The following will add an entry C<a to b> that transforms all C<a>s in
116the selection to C<b>s, but only if the selection currently contains any
117C<a>s:

137selection.
82 138
83=item digital-clock 139=item readline (enabled by default)
84 140
85Displays a digital clock using the built-in overlay. 141A support package that tries to make editing with readline easier. At the
142moment, it reacts to clicking with the left mouse button by trying to
143move the text cursor to this position. It does so by generating as many
144cursor-left or cursor-right keypresses as required (the this only works
145for programs that correctly support wide characters).
146
147To avoid too many false positives, this is only done when:
148
149=over 4
150
151=item - the tty is in ICANON state.
152
153=item - the text cursor is visible.
154
155=item - the primary screen is currently being displayed.
156
157=item - the mouse is on the same (multi-row-) line as the text cursor.
158
159=back
160
161The normal selection mechanism isn't disabled, so quick successive clicks
162might interfere with selection creation in harmless ways.
163
164=item selection-autotransform
165
166This selection allows you to do automatic transforms on a selection
167whenever a selection is made.
168
169It works by specifying perl snippets (most useful is a single C<s///>
170operator) that modify C<$_> as resources:
171
172 URxvt.selection-autotransform.0: transform
173 URxvt.selection-autotransform.1: transform
174 ...
175
176For example, the following will transform selections of the form
177C<filename:number>, often seen in compiler messages, into C<vi +$filename
178$word>:
179
180 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
181
182And this example matches the same,but replaces it with vi-commands you can
183paste directly into your (vi :) editor:
184
185 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
186
187Of course, this can be modified to suit your needs and your editor :)
188
189To expand the example above to typical perl error messages ("XXX at
190FILENAME line YYY."), you need a slightly more elaborate solution:
191
192 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
193 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
194
195The first line tells the selection code to treat the unchanging part of
196every error message as a selection pattern, and the second line transforms
197the message into vi commands to load the file.
198
199=item tabbed
200
201This transforms the terminal into a tabbar with additional terminals, that
202is, it implements what is commonly refered to as "tabbed terminal". The topmost line
203displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
204button per tab.
205
206Clicking a button will activate that tab. Pressing B<Shift-Left> and
207B<Shift-Right> will switch to the tab left or right of the current one,
208while B<Shift-Down> creates a new tab.

87=item mark-urls 210=item mark-urls
88 211
89Uses per-line display filtering (C<on_line_update>) to underline urls and 212Uses per-line display filtering (C<on_line_update>) to underline urls and
90make them clickable. When clicked, the program specified in the resource 213make them clickable. When middle-clicked, the program specified in the
91C<urlLauncher> (default C<x-www-browser>) will be started. 214resource C<urlLauncher> (default C<x-www-browser>) will be started with
215the URL as first argument.
216
217=item xim-onthespot
218
219This (experimental) perl extension implements OnTheSpot editing. It does
220not work perfectly, and some input methods don't seem to work well with
221OnTheSpot editing in general, but it seems to work at leats for SCIM and
222kinput2.
223
224You enable it by specifying this extension and a preedit style of
225C<OnTheSpot>, i.e.:

232to the window position, in effect creating the same effect as pseudo transparency with
233a custom pixmap. No scaling is supported in this mode. Exmaple:

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