74<p>Everytime a terminal object gets created, extension scripts specified via
75the <code>perl</code> resource are loaded and associated with it.</p>
76<p>Scripts are compiled in a 'use strict' and 'use utf8' environment, and
77thus must be encoded as UTF-8.</p>
78<p>Each script will only ever be loaded once, even in rxvtd, where
79scripts will be shared (but not enabled) for all terminals.</p>

83<h1><a name="prepackaged_extensions">PREPACKAGED EXTENSIONS</a></h1>
84<p>This section describes the extensions delivered with this release. You can
85find them in <em>/opt/rxvt/lib/urxvt/perl/</em>.</p>
86<p>You can activate them like this:</p>
87<pre>
88 rxvt -pe &lt;extensionname&gt;</pre>
89<p>Or by adding them to the resource for extensions loaded by default:</p>
90<pre>
91 URxvt.perl-ext-common: default,automove-background,selection-autotransform</pre>
92<dl>
93<dt><strong><a name="item_selection">selection (enabled by default)</a></strong>
94
95<dd>
96<p>(More) intelligent selection. This extension tries to be more intelligent
97when the user extends selections (double-click and further clicks). Right
98now, it tries to select words, urls and complete shell-quoted
99arguments, which is very convenient, too, if your <em>ls</em> supports
100<code>--quoting-style=shell</code>.</p>
101</dd>
102<dd>
103<p>A double-click usually selects the word under the cursor, further clicks
104will enlarge the selection.</p>
105</dd>
106<dd>
107<p>The selection works by trying to match a number of regexes and displaying
108them in increasing order of length. You can add your own regexes by
109specifying resources of the form:</p>
110</dd>
111<dd>
112<pre>
113 URxvt.selection.pattern-0: perl-regex
114 URxvt.selection.pattern-1: perl-regex
115 ...</pre>
116</dd>
117<dd>
118<p>The index number (0, 1...) must not have any holes, and each regex must
119contain at least one pair of capturing parentheses, which will be used for
120the match. For example, the followign adds a regex that matches everything
121between two vertical bars:</p>
122</dd>
123<dd>
124<pre>
125 URxvt.selection.pattern-0: \\|([^|]+)\\|</pre>
126</dd>
127<dd>
128<p>Another example: Programs I use often output ``absolute path: '' at the
129beginning of a line when they process multiple files. The following
130pattern matches the filename (note, there is a single space at the very
131end):</p>
132</dd>
133<dd>
134<pre>
135 URxvt.selection.pattern-0: ^(/[^:]+):\</pre>
136</dd>
137<dd>
138<p>You can look at the source of the selection extension to see more
139interesting uses, such as parsing a line from beginning to end.</p>
140</dd>
141<dd>
142<p>This extension also offers following bindable keyboard commands:</p>
143</dd>
144<dl>
145<dt><strong><a name="item_rot13">rot13</a></strong>
146
147<dd>
148<p>Rot-13 the selection when activated. Used via keyboard trigger:</p>
149</dd>
150<dd>
151<pre>
152 URxvt.keysym.C-M-r: perl:selection:rot13</pre>
153</dd>
154</li>
155</dl>
156<dt><strong><a name="item_popup">option-popup (enabled by default)</a></strong>
157
158<dd>
159<p>Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
160runtime.</p>
161</dd>
162<dd>
163<p>Other extensions can extend this popup menu by pushing a code reference
164onto <code>@{ $term-</code>{option_popup_hook} }&gt;, which gets called whenever the
165popup is being displayed.</p>
166</dd>
167<dd>
168<p>It's sole argument is the popup menu, which can be modified. It should
169either return nothing or a string, the initial boolean value and a code
170reference. The string will be used as button text and the code reference
171will be called when the toggle changes, with the new boolean value as
172first argument.</p>
173</dd>
174<dd>
175<p>The following will add an entry <code>myoption</code> that changes
176<code>$self-</code>{myoption}&gt;:</p>
177</dd>
178<dd>
179<pre>
180 push @{ $self-&gt;{term}{option_popup_hook} }, sub {
181 (&quot;my option&quot; =&gt; $myoption, sub { $self-&gt;{myoption} = $_[0] })
182 };</pre>
183</dd>
184</li>
185<dt><strong>selection-popup (enabled by default)</strong>
186
187<dd>
188<p>Binds a popup menu to Ctrl-Button3 that lets you convert the selection
189text into various other formats/action (such as uri unescaping, perl
190evaluation, web-browser starting etc.), depending on content.</p>
191</dd>
192<dd>
193<p>Other extensions can extend this popup menu by pushing a code reference
194onto <code>@{ $term-</code>{selection_popup_hook} }&gt;, which gets called whenever the
195popup is being displayed.</p>
196</dd>
197<dd>
198<p>It's sole argument is the popup menu, which can be modified. The selection
199is in <code>$_</code>, which can be used to decide wether to add something or not.
200It should either return nothing or a string and a code reference. The
201string will be used as button text and the code reference will be called
202when the button gets activated and should transform <code>$_</code>.</p>
203</dd>
204<dd>
205<p>The following will add an entry <code>a to b</code> that transforms all <code>a</code>s in
206the selection to <code>b</code>s, but only if the selection currently contains any
207<code>a</code>s:</p>
208</dd>
209<dd>
210<pre>
211 push @{ $self-&gt;{term}{selection_popup_hook} }, sub {
212 /a/ ? (&quot;a to be&quot; =&gt; sub { s/a/b/g }
213 : ()
214 };</pre>
215</dd>
216</li>
217<dt><strong><a name="item_searchable_2dscrollback_3chotkey_3e__28enabled_by_">searchable-scrollback&lt;hotkey&gt; (enabled by default)</a></strong>
218
219<dd>
220<p>Adds regex search functionality to the scrollback buffer, triggered
221by a hotkey (default: <code>M-s</code>). While in search mode, normal terminal
222input/output is suspended and a regex is displayed at the bottom of the
223screen.</p>
224</dd>
225<dd>
226<p>Inputting characters appends them to the regex and continues incremental
227search. <code>BackSpace</code> removes a character from the regex, <code>Up</code> and <code>Down</code>
228search upwards/downwards in the scrollback buffer, <code>End</code> jumps to the
229bottom. <code>Escape</code> leaves search mode and returns to the point where search
230was started, while <code>Enter</code> or <code>Return</code> stay at the current position and
231additionally stores the first match in the current line into the primary
232selection.</p>
233</dd>
234<dd>
235<p>The regex defaults to ``(?i)'', resulting in a case-insensitive search. To
236get a case-sensitive search you can delete this prefix using <code>BackSpace</code>
237or simply use an uppercase character which removes the ``(?i)'' prefix.</p>
238</dd>
239<dd>
240<p>See <em>perlre</em> for more info about perl regular expression syntax.</p>
241</dd>
242</li>
243<dt><strong><a name="item_readline">readline (enabled by default)</a></strong>
244
245<dd>
246<p>A support package that tries to make editing with readline easier. At
247the moment, it reacts to clicking shift-left mouse button by trying to
248move the text cursor to this position. It does so by generating as many
249cursor-left or cursor-right keypresses as required (the this only works
250for programs that correctly support wide characters).</p>
251</dd>
252<dd>
253<p>To avoid too many false positives, this is only done when:</p>
254</dd>
255<dl>
256<dt><strong><a name="item__2d_the_tty_is_in_icanon_state_2e">- the tty is in ICANON state.</a></strong>
257
258<dt><strong><a name="item__2d_the_text_cursor_is_visible_2e">- the text cursor is visible.</a></strong>
259
260<dt><strong><a name="item__2d_the_primary_screen_is_currently_being_displaye">- the primary screen is currently being displayed.</a></strong>
261
262<dt><strong><a name="item_same">- the mouse is on the same (multi-row-) line as the text cursor.</a></strong>
263
264</dl>
265<p>The normal selection mechanism isn't disabled, so quick successive clicks
266might interfere with selection creation in harmless ways.</p>
267<dt><strong><a name="item_selection_2dautotransform">selection-autotransform</a></strong>
268
269<dd>
270<p>This selection allows you to do automatic transforms on a selection
271whenever a selection is made.</p>
272</dd>
273<dd>
274<p>It works by specifying perl snippets (most useful is a single <code>s///</code>
275operator) that modify <code>$_</code> as resources:</p>
276</dd>
277<dd>
278<pre>
279 URxvt.selection-autotransform.0: transform
280 URxvt.selection-autotransform.1: transform
281 ...</pre>
282</dd>
283<dd>
284<p>For example, the following will transform selections of the form
285<code>filename:number</code>, often seen in compiler messages, into <code>vi +$filename
286$word</code>:</p>
287</dd>
288<dd>
289<pre>
290 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/</pre>
291</dd>
292<dd>
293<p>And this example matches the same,but replaces it with vi-commands you can
294paste directly into your (vi :) editor:</p>
295</dd>
296<dd>
297<pre>
298 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/</pre>
299</dd>
300<dd>
301<p>Of course, this can be modified to suit your needs and your editor :)</p>
302</dd>
303<dd>
304<p>To expand the example above to typical perl error messages (``XXX at
305FILENAME line YYY.''), you need a slightly more elaborate solution:</p>
306</dd>
307<dd>
308<pre>
309 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
310 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/</pre>
311</dd>
312<dd>
313<p>The first line tells the selection code to treat the unchanging part of
314every error message as a selection pattern, and the second line transforms
315the message into vi commands to load the file.</p>
316</dd>
317</li>
318<dt><strong><a name="item_tabbed">tabbed</a></strong>
319
320<dd>
321<p>This transforms the terminal into a tabbar with additional terminals, that
322is, it implements what is commonly refered to as ``tabbed terminal''. The topmost line
323displays a ``[NEW]'' button, which, when clicked, will add a new tab, followed by one
324button per tab.</p>
325</dd>
326<dd>
327<p>Clicking a button will activate that tab. Pressing <strong>Shift-Left</strong> and
328<strong>Shift-Right</strong> will switch to the tab left or right of the current one,
329while <strong>Shift-Down</strong> creates a new tab.</p>
330</dd>
331<dd>
332<p>The tabbar itself can be configured similarly to a normal terminal, but
333with a resource class of <code>URxvt.tabbed</code>. In addition, it supports the
334following four resources (shown with defaults):</p>
335</dd>
336<dd>
337<pre>
338 URxvt.tabbed.tabbar-fg: &lt;colour-index, default 3&gt;
339 URxvt.tabbed.tabbar-bg: &lt;colour-index, default 0&gt;
340 URxvt.tabbed.tab-fg: &lt;colour-index, default 0&gt;
341 URxvt.tabbed.tab-bg: &lt;colour-index, default 1&gt;</pre>
342</dd>
343<dd>
344<p>See <em>COLOR AND GRAPHICS</em> in the <code>rxvt(1)</code> manpage for valid
345indices.</p>
346</dd>
347</li>
348<dt><strong><a name="item_mark_2durls">mark-urls</a></strong>
349
350<dd>
351<p>Uses per-line display filtering (<code>on_line_update</code>) to underline urls and
352make them clickable. When middle-clicked, the program specified in the
353resource <code>urlLauncher</code> (default <code>x-www-browser</code>) will be started with
354the URL as first argument.</p>
355</dd>
356</li>
357<dt><strong><a name="item_xim_2donthespot">xim-onthespot</a></strong>
358
359<dd>
360<p>This (experimental) perl extension implements OnTheSpot editing. It does
361not work perfectly, and some input methods don't seem to work well with
362OnTheSpot editing in general, but it seems to work at leats for SCIM and
363kinput2.</p>
364</dd>
365<dd>
366<p>You enable it by specifying this extension and a preedit style of
367<code>OnTheSpot</code>, i.e.:</p>
368</dd>
369<dd>
370<pre>
371 rxvt -pt OnTheSpot -pe xim-onthespot</pre>
372</dd>
373</li>
374<dt><strong><a name="item_automove_2dbackground">automove-background</a></strong>
375
376<dd>
377<p>This is basically a very small extension that dynamically changes the
378background pixmap offset to the window position, in effect creating the
379same effect as pseudo transparency with a custom pixmap. No scaling is
380supported in this mode. Exmaple:</p>
381</dd>
382<dd>
383<pre>
384 rxvt -pixmap background.xpm -pe automove-background</pre>
385</dd>
386</li>
387<dt><strong><a name="item_block_2dgraphics_2dto_2dascii">block-graphics-to-ascii</a></strong>
388
389<dd>
390<p>A not very useful example of filtering all text output to the terminal
391by replacing all line-drawing characters (U+2500 .. U+259F) by a
392similar-looking ascii character.</p>
393</dd>
394</li>
395<dt><strong><a name="item_digital_2dclock">digital-clock</a></strong>
396
397<dd>
398<p>Displays a digital clock using the built-in overlay.</p>
399</dd>
400</li>
401<dt><strong><a name="item_remote_2dclipboard">remote-clipboard</a></strong>
402
403<dd>
404<p>Somewhat of a misnomer, this extension adds two menu entries to the
405selection popup that allows one ti run external commands to store the
406selection somewhere and fetch it again.</p>
407</dd>
408<dd>
409<p>We use it to implement a ``distributed selection mechanism'', which just
410means that one command uploads the file to a remote server, and another
411reads it.</p>
412</dd>
413<dd>
414<p>The commands can be set using the <code>URxvt.remote-selection.store</code> and
415<code>URxvt.remote-selection.fetch</code> resources. The first should read the
416selection to store from STDIN (always in UTF-8), the second should provide
417the selection data on STDOUT (also in UTF-8).</p>
418</dd>
419<dd>
420<p>The defaults (which are likely useless to you) use rsh and cat:</p>
421</dd>
422<dd>
423<pre>
424 URxvt.remote-selection.store: rsh ruth 'cat &gt;/tmp/distributed-selection'
425 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'</pre>
426</dd>
427</li>
428<dt><strong><a name="item_selection_2dpastebin">selection-pastebin</a></strong>
429
430<dd>
431<p>This is a little rarely useful extension that Uploads the selection as
432textfile to a remote site (or does other things). (The implementation is
433not currently secure for use in a multiuser environment as it writes to
434<em>/tmp</em> directly.).</p>
435</dd>
436<dd>
437<p>It listens to the <code>selection-pastebin:remote-pastebin</code> keyboard command,
438i.e.</p>
439</dd>
440<dd>
441<pre>
442 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin</pre>
443</dd>
444<dd>
445<p>Pressing this combination runs a command with <code>%</code> replaced by the name of
446the textfile. This command can be set via a resource:</p>
447</dd>
448<dd>
449<pre>
450 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.</pre>
451</dd>
452<dd>
453<p>And the default is likely not useful to anybody but the few people around
454here :)</p>
455</dd>
456<dd>
457<p>The name of the textfile is the hex encoded md5 sum of the selection, so
458the same content should lead to the same filename.</p>

486<p>All objects (such as terminals, time watchers etc.) are typical
487reference-to-hash objects. The hash can be used to store anything you
488like. All members starting with an underscore (such as <code>_ptr</code> or
489<code>_hook</code>) are reserved for internal uses and <strong>MUST NOT</strong> be accessed or
490modified).</p>
491<p>When objects are destroyed on the C++ side, the perl object hashes are
492emptied, so its best to store related objects such as time watchers and
493the like inside the terminal object so they get destroyed as soon as the
494terminal is destroyed.</p>
495<p>Argument names also often indicate the type of a parameter. Here are some
496hints on what they mean:</p>

523<h2><a name="extension_objects">Extension Objects</a></h2>
524<p>Every perl extension is a perl class. A separate perl object is created
525for each terminal and each extension and passed as the first parameter to
526hooks. So extensions can use their <code>$self</code> object without having to think
527about other extensions, with the exception of methods and members that
528begin with an underscore character <code>_</code>: these are reserved for internal
529use.</p>
530<p>Although it isn't a <code>urxvt::term</code> object, you can call all methods of the
531<code>urxvt::term</code> class on this object.</p>
