52C<--quoting-style=shell>.
48 53
49It also offers the following bindable event: 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.
81
82This extension also offers following bindable keyboard commands:

65 98
99Other extensions can extend this popup menu by pushing a code reference
100onto C<@{ $term->{option_popup_hook} }>, which gets called whenever the
101popup is being displayed.
102
103It's sole argument is the popup menu, which can be modified. It should
104either return nothing or a string, the initial boolean value and a code
105reference. The string will be used as button text and the code reference
106will be called when the toggle changes, with the new boolean value as
107first argument.
108
109The following will add an entry C<myoption> that changes
110C<$self->{myoption}>:

72 125
73Displays a digital clock using the built-in overlay. 126It's sole argument is the popup menu, which can be modified. The selection
127is in C<$_>, which can be used to decide wether to add something or not.
128It should either return nothing or a string and a code reference. The
129string will be used as button text and the code reference will be called
130when the button gets activated and should transform C<$_>.
131
132The following will add an entry C<a to b> that transforms all C<a>s in
133the selection to C<b>s, but only if the selection currently contains any
134C<a>s:
135
136 push @{ $self->{term}{selection_popup_hook} }, sub {
137 /a/ ? ("a to be" => sub { s/a/b/g }
138 : ()
139 };
140
141=item searchable-scrollback<hotkey> (enabled by default)
142
143Adds regex search functionality to the scrollback buffer, triggered
144by a hotkey (default: C<M-s>). While in search mode, normal terminal
145input/output is suspended and a regex is displayed at the bottom of the
146screen.
147
148Inputting characters appends them to the regex and continues incremental
149search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
150search upwards/downwards in the scrollback buffer, C<End> jumps to the
151bottom. C<Escape> leaves search mode and returns to the point where search
152was started, while C<Enter> or C<Return> stay at the current position and
153additionally stores the first match in the current line into the primary
154selection.
155
156=item readline (enabled by default)
157
158A support package that tries to make editing with readline easier. At
159the moment, it reacts to clicking shift-left mouse button by trying to
160move the text cursor to this position. It does so by generating as many
161cursor-left or cursor-right keypresses as required (the this only works
162for programs that correctly support wide characters).
163
164To avoid too many false positives, this is only done when:
165
166=over 4
167
168=item - the tty is in ICANON state.
169
170=item - the text cursor is visible.
171
172=item - the primary screen is currently being displayed.
173
174=item - the mouse is on the same (multi-row-) line as the text cursor.
175
176=back
177
178The normal selection mechanism isn't disabled, so quick successive clicks
179might interfere with selection creation in harmless ways.
180
181=item selection-autotransform
182
183This selection allows you to do automatic transforms on a selection
184whenever a selection is made.
185
186It works by specifying perl snippets (most useful is a single C<s///>
187operator) that modify C<$_> as resources:
188
189 URxvt.selection-autotransform.0: transform
190 URxvt.selection-autotransform.1: transform
191 ...
192
193For example, the following will transform selections of the form
194C<filename:number>, often seen in compiler messages, into C<vi +$filename
195$word>:
196
197 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
198
199And this example matches the same,but replaces it with vi-commands you can
200paste directly into your (vi :) editor:
201
202 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
203
204Of course, this can be modified to suit your needs and your editor :)
205
206To expand the example above to typical perl error messages ("XXX at
207FILENAME line YYY."), you need a slightly more elaborate solution:
208
209 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
210 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
211
212The first line tells the selection code to treat the unchanging part of
213every error message as a selection pattern, and the second line transforms
214the message into vi commands to load the file.
215
216=item tabbed
217
218This transforms the terminal into a tabbar with additional terminals, that
219is, it implements what is commonly refered to as "tabbed terminal". The topmost line
220displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
221button per tab.
222
223Clicking a button will activate that tab. Pressing B<Shift-Left> and
224B<Shift-Right> will switch to the tab left or right of the current one,
225while B<Shift-Down> creates a new tab.
226
227The tabbar itself can be configured similarly to a normal terminal, but
228with a resource class of C<URxvt.tabbed>. In addition, it supports the
229following four resources (shown with defaults):
230
231 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
232 URxvt.tabbed.tabbar-bg: <colour-index, default 0>
233 URxvt.tabbed.tab-fg: <colour-index, default 0>
234 URxvt.tabbed.tab-bg: <colour-index, default 1>
235
236See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
237indices.

242make them clickable. When middle-clicked, the program specified in the
243resource C<urlLauncher> (default C<x-www-browser>) will be started with
244the URL as first argument.
245
246=item xim-onthespot
247
248This (experimental) perl extension implements OnTheSpot editing. It does
249not work perfectly, and some input methods don't seem to work well with
250OnTheSpot editing in general, but it seems to work at leats for SCIM and
251kinput2.
252
253You enable it by specifying this extension and a preedit style of
254C<OnTheSpot>, i.e.:
255

258=item automove-background
259
260This is basically a one-line extension that dynamically changes the background pixmap offset
261to the window position, in effect creating the same effect as pseudo transparency with
262a custom pixmap. No scaling is supported in this mode. Exmaple:

272=item digital-clock
273
274Displays a digital clock using the built-in overlay.
275
276=item remote-clipboard
277
278Somewhat of a misnomer, this extension adds two menu entries to the
279selection popup that allows one ti run external commands to store the
280selection somewhere and fetch it again.
281
282We use it to implement a "distributed selection mechanism", which just
283means that one command uploads the file to a remote server, and another
284reads it.
285
286The commands can be set using the C<URxvt.remote-selection.store> and
287C<URxvt.remote-selection.fetch> resources. The first should read the
288selection to store from STDIN (always in UTF-8), the second should provide
289the selection data on STDOUT (also in UTF-8).
290
291The defaults (which are likely useless to you) use rsh and cat:
292
293 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
294 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
295
296=item selection-pastebin
297
298This is a little rarely useful extension that Uploads the selection as
299textfile to a remote site (or does other things). (The implementation is
300not currently secure for use in a multiuser environment as it writes to
301F</tmp> directly.).
302
303It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
304i.e.
305
306 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
307
308Pressing this combination runs a command with C<%> replaced by the name of
309the textfile. This command can be set via a resource:
310
311 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
312
313And the default is likely not useful to anybody but the few people around
314here :)
315
316The name of the textfile is the hex encoded md5 sum of the selection, so
317the same content should lead to the same filename.
318
319After a successful upload the selection will be replaced by the text given
320in the C<selection-pastebin-url> resource (again, the % is the placeholder
321for the filename):
322
323 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

371=head2 Extension Objects
372
373Very perl extension is a perl class. A separate perl object is created
374for each terminal and each extension and passed as the first parameter to
375hooks. So extensions can use their C<$self> object without having to think
376about other extensions, with the exception of methods and members that
377begin with an underscore character C<_>: these are reserved for internal
378use.
379
380Although it isn't a C<urxvt::term> object, you can call all methods of the
381C<urxvt::term> class on this object.
