45 49which can be bound to a key and invoked by the user. An extension can

47 51described below. Similarly to builtin resources, extension resources
48(More) intelligent selection. This extension tries to be more intelligent 52can also be specified on the command line as long options (with C<.>
49when the user extends selections (double-click and further clicks). Right 53replaced by C<->), in which case the corresponding extension is loaded
50now, it tries to select words, urls and complete shell-quoted 54automatically. For this to work the extension B<must> define META
51arguments, which is very convenient, too, if your F<ls> supports 55comments for its resources.
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 matcher
246
247Uses per-line display filtering (C<on_line_update>) to underline text
248matching a certain pattern and make it clickable. When clicked with the
249mouse button specified in the C<matcher.button> resource (default 2, or
250middle), the program specified in the C<matcher.launcher> resource
251(default, the C<urlLauncher> resource, C<sensible-browser>) will be started
252with the matched text as first argument. The default configuration is
253suitable for matching URLs and launching a web browser, like the
254former "mark-urls" extension.
255
256The default pattern to match URLs can be overridden with the
257C<matcher.pattern.0> resource, and additional patterns can be specified
258with numbered patterns, in a manner similar to the "selection" extension.
259The launcher can also be overridden on a per-pattern basis.
260
261Example configuration:
262
263 URxvt.perl-ext: default,matcher
264 URxvt.urlLauncher: sensible-browser
265 URxvt.keysym.C-Delete: perl:matcher
266 URxvt.matcher.button: 1
267 URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-]
268 URxvt.matcher.pattern.2: \\B(/\\S+?):(\\d+)(?=:|$)
269 URxvt.matcher.launcher.2: gvim +$2 $1
270
271=item xim-onthespot
272
273This (experimental) perl extension implements OnTheSpot editing. It does
274not work perfectly, and some input methods don't seem to work well with
275OnTheSpot editing in general, but it seems to work at leats for SCIM and
276kinput2.
277
278You enable it by specifying this extension and a preedit style of
279C<OnTheSpot>, i.e.:
280
281 @@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
282
283=item kuake<hotkey>
284
285A very primitive quake-console-like extension. It was inspired by a
286description of how the programs C<kuake> and C<yakuake> work: Whenever the
287user presses a global accelerator key (by default C<F10>), the terminal
288will show or hide itself. Another press of the accelerator key will hide
289or show it again.
290
291Initially, the window will not be shown when using this extension.
292
293This is useful if you need a single terminal thats not using any desktop
294space most of the time but is quickly available at the press of a key.
295
296The accelerator key is grabbed regardless of any modifiers, so this
297extension will actually grab a physical key just for this function.
298
299If you want a quake-like animation, tell your window manager to do so
300(fvwm can do it).
301
302=item automove-background
303
304This is basically a very small extension that dynamically changes the
305background pixmap offset to the window position, in effect creating the
306same effect as pseudo transparency with a custom pixmap. No scaling is
307supported in this mode. Example:
308
309 @@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
310
311L<http://wiki.archlinux.org/index.php/Perl_Background_Rotation/Extensions>
312shows how this extension can be used to implement an automatically blurred
313transparent background.
314
315=item block-graphics-to-ascii
316
317A not very useful example of filtering all text output to the terminal
318by replacing all line-drawing characters (U+2500 .. U+259F) by a
319similar-looking ascii character.
320
321=item digital-clock
322
323Displays a digital clock using the built-in overlay.
324
325=item remote-clipboard
326
327Somewhat of a misnomer, this extension adds two menu entries to the
328selection popup that allows one ti run external commands to store the
329selection somewhere and fetch it again.
330
331We use it to implement a "distributed selection mechanism", which just
332means that one command uploads the file to a remote server, and another
333reads it.
334
335The commands can be set using the C<URxvt.remote-selection.store> and
336C<URxvt.remote-selection.fetch> resources. The first should read the
337selection to store from STDIN (always in UTF-8), the second should provide
338the selection data on STDOUT (also in UTF-8).
339
340The defaults (which are likely useless to you) use rsh and cat:
341
342 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
343 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
344
345=item selection-pastebin
346
347This is a little rarely useful extension that Uploads the selection as
348textfile to a remote site (or does other things). (The implementation is
349not currently secure for use in a multiuser environment as it writes to
350F</tmp> directly.).
351
352It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
353i.e.
354
355 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
356
357Pressing this combination runs a command with C<%> replaced by the name of
358the textfile. This command can be set via a resource:
359
360 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
361
362And the default is likely not useful to anybody but the few people around
363here :)
364
365The name of the textfile is the hex encoded md5 sum of the selection, so
366the same content should lead to the same filename.
367
368After a successful upload the selection will be replaced by the text given
369in the C<selection-pastebin-url> resource (again, the % is the placeholder
370for the filename):
371
372 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
373
374I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
375the double C</> characters as comment start. Use C<\057\057> instead,
376which works regardless of wether xrdb is used to parse the resource file
377or not.
378
379=item example-refresh-hooks
380
381Displays a very simple digital clock in the upper right corner of the
382window. Illustrates overwriting the refresh callbacks to create your own
383overlays or changes.

909This is useful when you want to overwrite time-critical hooks only

1342Extensions that define extra resources also need to call this method
1343to access their values.
1344
1345If the method is called on an extension object (basically, from an
1346extension), then the special prefix C<%.> will be replaced by the name of
1347the extension and a dot, and the lone string C<%> will be replaced by the
1348extension name itself. This makes it possible to code extensions so you
1349can rename them and get a new set of resources without having to change
1350the actual code.

1359and returns C<1> for true values, C<0> for false values and C<undef> if
1360the resource or option isn't specified.

1382To add default bindings for actions, an extension should call C<<

1384in the C<init> hook allows users to override or remove the binding
1385again.
