46=item selection (enabled by default)
47
48(More) intelligent selection. This extension tries to be more intelligent
49when the user extends selections (double-click and further clicks). Right
50now, it tries to select words, urls and complete shell-quoted
51arguments, which is very convenient, too, if your F<ls> supports
52C<--quoting-style=shell>.
53
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 following 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:
83
84=over 4
85
86=item rot13
87
88Rot-13 the selection when activated. Used via keyboard trigger:
89
90 URxvt.keysym.C-M-r: perl:selection:rot13
91
92=back
93
94=item option-popup (enabled by default)
95
96Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
97runtime.
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}>:
111
112 push @{ $self->{term}{option_popup_hook} }, sub {
113 ("my option" => $myoption, sub { $self->{myoption} = $_[0] })
114 };
115
116=item selection-popup (enabled by default)
117
118Binds a popup menu to Ctrl-Button3 that lets you convert the selection
119text into various other formats/action (such as uri unescaping, perl
120evaluation, web-browser starting etc.), depending on content.
121
122Other extensions can extend this popup menu by pushing a code reference
123onto C<@{ $term->{selection_popup_hook} }>, which gets called whenever the
124popup is being displayed.
125
126It's sole argument is the popup menu, which can be modified. The selection
127is in C<$_>, which can be used to decide whether 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
156The regex defaults to "(?i)", resulting in a case-insensitive search. To
157get a case-sensitive search you can delete this prefix using C<BackSpace>
158or simply use an uppercase character which removes the "(?i)" prefix.
159
160See L<perlre> for more info about perl regular expression syntax.
161
162=item readline (enabled by default)
163
164A support package that tries to make editing with readline easier. At
165the moment, it reacts to clicking shift-left mouse button by trying to
166move the text cursor to this position. It does so by generating as many
167cursor-left or cursor-right keypresses as required (the this only works
168for programs that correctly support wide characters).
169
170To avoid too many false positives, this is only done when:
171
172=over 4
173
174=item - the tty is in ICANON state.
175
176=item - the text cursor is visible.
177
178=item - the primary screen is currently being displayed.
179
180=item - the mouse is on the same (multi-row-) line as the text cursor.
181
182=back
183
184The normal selection mechanism isn't disabled, so quick successive clicks
185might interfere with selection creation in harmless ways.
186
187=item selection-autotransform
188
189This selection allows you to do automatic transforms on a selection
190whenever a selection is made.
191
192It works by specifying perl snippets (most useful is a single C<s///>
193operator) that modify C<$_> as resources:
194
195 URxvt.selection-autotransform.0: transform
196 URxvt.selection-autotransform.1: transform
197 ...
198
199For example, the following will transform selections of the form
200C<filename:number>, often seen in compiler messages, into C<vi +$filename
201$word>:
202
203 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
204
205And this example matches the same,but replaces it with vi-commands you can
206paste directly into your (vi :) editor:
207
208 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
209
210Of course, this can be modified to suit your needs and your editor :)
211
212To expand the example above to typical perl error messages ("XXX at
213FILENAME line YYY."), you need a slightly more elaborate solution:
214
215 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
216 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
217
218The first line tells the selection code to treat the unchanging part of
219every error message as a selection pattern, and the second line transforms
220the message into vi commands to load the file.
221
222=item tabbed
223
224This transforms the terminal into a tabbar with additional terminals, that
225is, it implements what is commonly referred to as "tabbed terminal". The topmost line
226displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
227button per tab.
228
229Clicking a button will activate that tab. Pressing B<Shift-Left> and
230B<Shift-Right> will switch to the tab left or right of the current one,
231while B<Shift-Down> creates a new tab.
232
233The tabbar itself can be configured similarly to a normal terminal, but
234with a resource class of C<URxvt.tabbed>. In addition, it supports the
235following four resources (shown with defaults):
236
237 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
238 URxvt.tabbed.tabbar-bg: <colour-index, default 0>
239 URxvt.tabbed.tab-fg: <colour-index, default 0>
240 URxvt.tabbed.tab-bg: <colour-index, default 1>
241
242See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
243indices.
244
245=item mark-urls
246
247Uses per-line display filtering (C<on_line_update>) to underline urls and
248make them clickable. When middle-clicked, the program specified in the
249resource C<urlLauncher> (default C<x-www-browser>) will be started with
250the URL as first argument.
251
252=item xim-onthespot
253
254This (experimental) perl extension implements OnTheSpot editing. It does
255not work perfectly, and some input methods don't seem to work well with
256OnTheSpot editing in general, but it seems to work at leats for SCIM and
257kinput2.
258
259You enable it by specifying this extension and a preedit style of
260C<OnTheSpot>, i.e.:
261
262 @@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
263
264=item kuake<hotkey>
265
266A very primitive quake-console-like extension. It was inspired by a
267description of how the programs C<kuake> and C<yakuake> work: Whenever the
268user presses a global accelerator key (by default C<F10>), the terminal
269will show or hide itself. Another press of the accelerator key will hide
270or show it again.
271
272Initially, the window will not be shown when using this extension.
273
274This is useful if you need a single terminal thats not using any desktop
275space most of the time but is quickly available at the press of a key.
276
277The accelerator key is grabbed regardless of any modifiers, so this
278extension will actually grab a physical key just for this function.
279
280If you want a quake-like animation, tell your window manager to do so
281(fvwm can do it).
282
283=item automove-background
284
285This is basically a very small extension that dynamically changes the
286background pixmap offset to the window position, in effect creating the
287same effect as pseudo transparency with a custom pixmap. No scaling is
288supported in this mode. Example:
289
290 @@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
291
292=item block-graphics-to-ascii
293
294A not very useful example of filtering all text output to the terminal
295by replacing all line-drawing characters (U+2500 .. U+259F) by a
296similar-looking ascii character.
297
298=item digital-clock
299
300Displays a digital clock using the built-in overlay.
301
302=item remote-clipboard
303
304Somewhat of a misnomer, this extension adds two menu entries to the
305selection popup that allows one ti run external commands to store the
306selection somewhere and fetch it again.
307
308We use it to implement a "distributed selection mechanism", which just
309means that one command uploads the file to a remote server, and another
310reads it.
311
312The commands can be set using the C<URxvt.remote-selection.store> and
313C<URxvt.remote-selection.fetch> resources. The first should read the
314selection to store from STDIN (always in UTF-8), the second should provide
315the selection data on STDOUT (also in UTF-8).
316
317The defaults (which are likely useless to you) use rsh and cat:
318
319 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
320 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
321
322=item selection-pastebin
323
324This is a little rarely useful extension that Uploads the selection as
325textfile to a remote site (or does other things). (The implementation is
326not currently secure for use in a multiuser environment as it writes to
327F</tmp> directly.).
328
329It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
330i.e.
331
332 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
333
334Pressing this combination runs a command with C<%> replaced by the name of
335the textfile. This command can be set via a resource:
336
337 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
338
339And the default is likely not useful to anybody but the few people around
340here :)
341
342The name of the textfile is the hex encoded md5 sum of the selection, so
343the same content should lead to the same filename.
344
345After a successful upload the selection will be replaced by the text given
346in the C<selection-pastebin-url> resource (again, the % is the placeholder
347for the filename):
348
349 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
350
351=item example-refresh-hooks
352
353Displays a very simple digital clock in the upper right corner of the
354window. Illustrates overwriting the refresh callbacks to create your own
355overlays or changes.

862Dynamically enable the given hooks (named without the C<on_> prefix) for
863this extension, replacing any hook previously installed via C<enable> in
864this extension.

866This is useful when you want to overwrite time-critical hooks only
867temporarily.
