47=over 4 48Extensions may add additional resources and C<actions>, i.e., methods
48 49which can be bound to a key and invoked by the user. An extension can
49=item selection (enabled by default) 50define the resources it support using so called META comments,
50 51described below. Similarly to builtin resources, extension resources
51(More) intelligent selection. This extension tries to be more intelligent 52can also be specified on the command line as long options (with C<.>
52when the user extends selections (double-click and further clicks). Right 53replaced by C<->), in which case the corresponding extension is loaded
53now, it tries to select words, urls and complete shell-quoted 54automatically. For this to work the extension B<must> define META
54arguments, which is very convenient, too, if your F<ls> supports 55comments for its resources.
55C<--quoting-style=shell>.
56
57A double-click usually selects the word under the cursor, further clicks
58will enlarge the selection.
59
60The selection works by trying to match a number of regexes and displaying
61them in increasing order of length. You can add your own regexes by
62specifying resources of the form:
63
64 URxvt.selection.pattern-0: perl-regex
65 URxvt.selection.pattern-1: perl-regex
66 ...
67
68The index number (0, 1...) must not have any holes, and each regex must
69contain at least one pair of capturing parentheses, which will be used for
70the match. For example, the following adds a regex that matches everything
71between two vertical bars:
72
73 URxvt.selection.pattern-0: \\|([^|]+)\\|
74
75Another example: Programs I use often output "absolute path: " at the
76beginning of a line when they process multiple files. The following
77pattern matches the filename (note, there is a single space at the very
78end):
79
80 URxvt.selection.pattern-0: ^(/[^:]+):\
81
82You can look at the source of the selection extension to see more
83interesting uses, such as parsing a line from beginning to end.
84
85This extension also offers following bindable keyboard commands:
86
87=over 4
88
89=item rot13
90
91Rot-13 the selection when activated. Used via keyboard trigger:
92
93 URxvt.keysym.C-M-r: perl:selection:rot13
94
95=back
96
97=item option-popup (enabled by default)
98
99Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
100runtime.
101
102Other extensions can extend this popup menu by pushing a code reference
103onto C<@{ $term->{option_popup_hook} }>, which gets called whenever the
104popup is being displayed.
105
106Its sole argument is the popup menu, which can be modified. It should
107either return nothing or a string, the initial boolean value and a code
108reference. The string will be used as button text and the code reference
109will be called when the toggle changes, with the new boolean value as
110first argument.
111
112The following will add an entry C<myoption> that changes
113C<< $self->{myoption} >>:
114
115 push @{ $self->{term}{option_popup_hook} }, sub {
116 ("my option" => $myoption, sub { $self->{myoption} = $_[0] })
117 };
118
119=item selection-popup (enabled by default)
120
121Binds a popup menu to Ctrl-Button3 that lets you convert the selection
122text into various other formats/action (such as uri unescaping, perl
123evaluation, web-browser starting etc.), depending on content.
124
125Other extensions can extend this popup menu by pushing a code reference
126onto C<@{ $term->{selection_popup_hook} }>, which gets called whenever the
127popup is being displayed.
128
129Its sole argument is the popup menu, which can be modified. The selection
130is in C<$_>, which can be used to decide whether to add something or not.
131It should either return nothing or a string and a code reference. The
132string will be used as button text and the code reference will be called
133when the button gets activated and should transform C<$_>.
134
135The following will add an entry C<a to b> that transforms all C<a>s in
136the selection to C<b>s, but only if the selection currently contains any
137C<a>s:
138
139 push @{ $self->{term}{selection_popup_hook} }, sub {
140 /a/ ? ("a to b" => sub { s/a/b/g }
141 : ()
142 };
143
144=item searchable-scrollback<hotkey> (enabled by default)
145
146Adds regex search functionality to the scrollback buffer, triggered
147by a hotkey (default: C<M-s>). While in search mode, normal terminal
148input/output is suspended and a regex is displayed at the bottom of the
149screen.
150
151Inputting characters appends them to the regex and continues incremental
152search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
153search upwards/downwards in the scrollback buffer, C<End> jumps to the
154bottom. C<Escape> leaves search mode and returns to the point where search
155was started, while C<Enter> or C<Return> stay at the current position and
156additionally stores the first match in the current line into the primary
157selection if the C<Shift> modifier is active.
158
159The regex defaults to "(?i)", resulting in a case-insensitive search. To
160get a case-sensitive search you can delete this prefix using C<BackSpace>
161or simply use an uppercase character which removes the "(?i)" prefix.
162
163See L<perlre> for more info about perl regular expression syntax.
164
165=item readline (enabled by default)
166
167A support package that tries to make editing with readline easier. At
168the moment, it reacts to clicking shift-left mouse button by trying to
169move the text cursor to this position. It does so by generating as many
170cursor-left or cursor-right keypresses as required (this only works
171for programs that correctly support wide characters).
172
173To avoid too many false positives, this is only done when:
174
175=over 4
176
177=item - the tty is in ICANON state.
178
179=item - the text cursor is visible.
180
181=item - the primary screen is currently being displayed.
182
183=item - the mouse is on the same (multi-row-) line as the text cursor.
184
185=back
186
187The normal selection mechanism isn't disabled, so quick successive clicks
188might interfere with selection creation in harmless ways.
189
190=item selection-autotransform
191
192This selection allows you to do automatic transforms on a selection
193whenever a selection is made.
194
195It works by specifying perl snippets (most useful is a single C<s///>
196operator) that modify C<$_> as resources:
197
198 URxvt.selection-autotransform.0: transform
199 URxvt.selection-autotransform.1: transform
200 ...
201
202For example, the following will transform selections of the form
203C<filename:number>, often seen in compiler messages, into C<vi +$filename
204$word>:
205
206 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
207
208And this example matches the same,but replaces it with vi-commands you can
209paste directly into your (vi :) editor:
210
211 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
212
213Of course, this can be modified to suit your needs and your editor :)
214
215To expand the example above to typical perl error messages ("XXX at
216FILENAME line YYY."), you need a slightly more elaborate solution:
217
218 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
219 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
220
221The first line tells the selection code to treat the unchanging part of
222every error message as a selection pattern, and the second line transforms
223the message into vi commands to load the file.
224
225=item tabbed
226
227This transforms the terminal into a tabbar with additional terminals, that
228is, it implements what is commonly referred to as "tabbed terminal". The topmost line
229displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
230button per tab.
231
232Clicking a button will activate that tab. Pressing B<Shift-Left> and
233B<Shift-Right> will switch to the tab left or right of the current one,
234while B<Shift-Down> creates a new tab.
235
236The tabbar itself can be configured similarly to a normal terminal, but
237with a resource class of C<URxvt.tabbed>. In addition, it supports the
238following four resources (shown with defaults):
239
240 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
241 URxvt.tabbed.tabbar-bg: <colour-index, default 0>
242 URxvt.tabbed.tab-fg: <colour-index, default 0>
243 URxvt.tabbed.tab-bg: <colour-index, default 1>
244
245See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
246indices.
247
248=item matcher
249
250Uses per-line display filtering (C<on_line_update>) to underline text
251matching a certain pattern and make it clickable. When clicked with the
252mouse button specified in the C<matcher.button> resource (default 2, or
253middle), the program specified in the C<matcher.launcher> resource
254(default, the C<urlLauncher> resource, C<sensible-browser>) will be started
255with the matched text as first argument. The default configuration is
256suitable for matching URLs and launching a web browser, like the
257former "mark-urls" extension.
258
259The default pattern to match URLs can be overridden with the
260C<matcher.pattern.0> resource, and additional patterns can be specified
261with numbered patterns, in a manner similar to the "selection" extension.
262The launcher can also be overridden on a per-pattern basis.
263
264It is possible to activate the most recently seen match or a list of matches
265from the keyboard. Simply bind a keysym to "perl:matcher:last" or
266"perl:matcher:list" as seen in the example below.
267
268Example configuration:
269
270 URxvt.perl-ext: default,matcher
271 URxvt.urlLauncher: sensible-browser
272 URxvt.keysym.C-Delete: perl:matcher:last
273 URxvt.keysym.M-Delete: perl:matcher:list
274 URxvt.matcher.button: 1
275 URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-]
276 URxvt.matcher.pattern.2: \\B(/\\S+?):(\\d+)(?=:|$)
277 URxvt.matcher.launcher.2: gvim +$2 $1
278
279=item xim-onthespot
280
281This (experimental) perl extension implements OnTheSpot editing. It does
282not work perfectly, and some input methods don't seem to work well with
283OnTheSpot editing in general, but it seems to work at least for SCIM and
284kinput2.
285
286You enable it by specifying this extension and a preedit style of
287C<OnTheSpot>, i.e.:
288
289 @@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
290
291=item kuake<hotkey>
292
293A very primitive quake-console-like extension. It was inspired by a
294description of how the programs C<kuake> and C<yakuake> work: Whenever the
295user presses a global accelerator key (by default C<F10>), the terminal
296will show or hide itself. Another press of the accelerator key will hide
297or show it again.
298
299Initially, the window will not be shown when using this extension.
300
301This is useful if you need a single terminal that is not using any desktop
302space most of the time but is quickly available at the press of a key.
303
304The accelerator key is grabbed regardless of any modifiers, so this
305extension will actually grab a physical key just for this function.
306
307If you want a quake-like animation, tell your window manager to do so
308(fvwm can do it).
309
310=item overlay-osc
311
312This extension implements some OSC commands to display timed popups on the
313screen - useful for status displays from within scripts. You have to read
314the sources for more info.
315
316=item block-graphics-to-ascii
317
318A not very useful example of filtering all text output to the terminal
319by replacing all line-drawing characters (U+2500 .. U+259F) by a
320similar-looking ascii character.
321
322=item digital-clock
323
324Displays a digital clock using the built-in overlay.
325
326=item remote-clipboard
327
328Somewhat of a misnomer, this extension adds two menu entries to the
329selection popup that allows one to run external commands to store the
330selection somewhere and fetch it again.
331
332We use it to implement a "distributed selection mechanism", which just
333means that one command uploads the file to a remote server, and another
334reads it.
335
336The commands can be set using the C<URxvt.remote-selection.store> and
337C<URxvt.remote-selection.fetch> resources. The first should read the
338selection to store from STDIN (always in UTF-8), the second should provide
339the selection data on STDOUT (also in UTF-8).
340
341The defaults (which are likely useless to you) use rsh and cat:
342
343 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
344 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
345
346=item selection-pastebin
347
348This is a little rarely useful extension that uploads the selection as
349textfile to a remote site (or does other things). (The implementation is
350not currently secure for use in a multiuser environment as it writes to
351F</tmp> directly.).
352
353It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
354i.e.
355
356 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
357
358Pressing this combination runs a command with C<%> replaced by the name of
359the textfile. This command can be set via a resource:
360
361 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
362
363And the default is likely not useful to anybody but the few people around
364here :)
365
366The name of the textfile is the hex encoded md5 sum of the selection, so
367the same content should lead to the same filename.
368
369After a successful upload the selection will be replaced by the text given
370in the C<selection-pastebin-url> resource (again, the % is the placeholder
371for the filename):
372
373 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
374
375I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
376the double C</> characters as comment start. Use C<\057\057> instead,
377which works regardless of whether xrdb is used to parse the resource file
378or not.
379
380=item macosx-clipboard and macosx-clipboard-native
381
382These two modules implement an extended clipboard for Mac OS X. They are
383used like this:
384
385 URxvt.perl-ext-common: default,macosx-clipboard
386 URxvt.keysym.M-c: perl:macosx-clipboard:copy
387 URxvt.keysym.M-v: perl:macosx-clipboard:paste
388
389The difference between them is that the native variant requires a
390perl from apple's devkit or so, and C<macosx-clipboard> requires the
391C<Mac::Pasteboard> module, works with other perls, has fewer bugs, is
392simpler etc. etc.
393
394=item example-refresh-hooks
395
396Displays a very simple digital clock in the upper right corner of the
397window. Illustrates overwriting the refresh callbacks to create your own
398overlays or changes.
399
400=item confirm-paste
401
402Displays a confirmation dialog when a paste containing at least a full
403line is detected.
404
405=item bell-command
406
407Runs the command specified by the C<URxvt.bell-command> resource when
408a bell event occurs. For example, the following pops up a notification
409bubble with the text "Beep, Beep" using notify-send:
410

1322to access their values.

1325extension), then the special prefix C<%.> will be replaced by the name of
1326the extension and a dot, and the lone string C<%> will be replaced by the
1327extension name itself. This makes it possible to code extensions so you
1328can rename them and get a new set of resources without having to change
