81</dt> 92</dt>
93<dd>
94(More) intelligent selection. This extension tries to be more intelligent
95when the user extends selections (double-click and further clicks). Right
96now, it tries to select words, urls and complete shell-quoted
97arguments, which is very convenient, too, if your <em>ls</em> supports
98<code>--quoting-style=shell</code>.
82<dd> 99</dd>
83Miscellaneous selection modifications. 100<dd>
101<p>A double-click usually selects the word under the cursor, further clicks
102will enlarge the selection.</p>
103</dd>
104<dd>
105<p>The selection works by trying to match a number of regexes and displaying
106them in increasing order of length. You can add your own regexes by
107specifying resources of the form:</p>
108</dd>
109<dd>
110<pre>
111 URxvt.selection.pattern-0: perl-regex
112 URxvt.selection.pattern-1: perl-regex
113 ...</pre>
114</dd>
115<dd>
116<p>The index number (0, 1...) must not have any holes, and each regex must
117contain at least one pair of capturing parentheses, which will be used for
118the match. For example, the followign adds a regex that matches everything
119between two vertical bars:</p>
120</dd>
121<dd>
122<pre>
123 URxvt.selection.pattern-0: \\|([^|]+)\\|</pre>
124</dd>
125<dd>
126<p>Another example: Programs I use often output ``absolute path: '' at the
127beginning of a line when they process multiple files. The following
128pattern matches the filename (note, there is a single space at the very
129end):</p>
130</dd>
131<dd>
132<pre>
133 URxvt.selection.pattern-0: ^(/[^:]+):\</pre>
134</dd>
135<dd>
136<p>You can look at the source of the selection extension to see more
137interesting uses, such as parsing a line from beginning to end.</p>
138</dd>
139<dd>
140<p>This extension also offers following bindable keyboard commands:</p>

95<p></p></dl> 152<p></p></dl>
153<dt><strong><a name="item_popup">option-popup (enabled by default)</a></strong><br />
154</dt>
155<dd>
156Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
157runtime.
158</dd>
159<p></p>
160<dt><strong>selection-popup (enabled by default)</strong><br />
161</dt>
162<dd>
163Binds a popup menu to Ctrl-Button3 that lets you convert the selection
164text into various other formats/action (such as uri unescaping, perl
165evaluation, web-browser starting etc.), depending on content.
166</dd>
167<dd>
168<p>Other extensions can extend this popup menu by pushing a code reference
169onto <code>@{ $term-</code>{selection_popup_hook} }&gt;, that is called whenever the
170popup is displayed.</p>
171</dd>
172<dd>
173<p>It's sole argument is the popup menu, which can be modified. The selection
174is in <code>$_</code>, which can be used to decide wether to add something or not.
175It should either return nothing or a string and a code reference. The
176string will be used as button text and the code reference will be called
177when the button gets activated and should transform <code>$_</code>.</p>
178</dd>
179<dd>
180<p>The following will add an entry <code>a to b</code> that transforms all <code>a</code>s in
181the selection to <code>b</code>s, but only if the selection currently contains any
182<code>a</code>s:</p>
183</dd>
184<dd>
185<pre>
186 push @{ $self-&gt;{term}{selection_popup_hook} }, sub {
187 /a/ ? (&quot;a to be&quot; =&gt; sub { s/a/b/g }
188 : ()
189 };</pre>
190</dd>
191<p></p>
192<dt><strong><a name="item_searchable_2dscrollback_3chotkey_3e__28enabled_by_">searchable-scrollback&lt;hotkey&gt; (enabled by default)</a></strong><br />
193</dt>
194<dd>
195Adds regex search functionality to the scrollback buffer, triggered
196by a hotkey (default: <code>M-s</code>). While in search mode, normal terminal
197input/output is suspended and a regex is displayed at the bottom of the
198screen.
199</dd>
200<dd>
201<p>Inputting characters appends them to the regex and continues incremental
202search. <code>BackSpace</code> removes a character from the regex, <code>Up</code> and <code>Down</code>
203search upwards/downwards in the scrollback buffer, <code>End</code> jumps to the
204bottom. <code>Escape</code> leaves search mode and returns to the point where search
205was started, while <code>Enter</code> or <code>Return</code> stay at the current position and
206additionally stores the first match in the current line into the primary
207selection.</p>
208</dd>
209<p></p>
210<dt><strong><a name="item_readline">readline (enabled by default)</a></strong><br />
211</dt>
212<dd>
213A support package that tries to make editing with readline easier. At the
214moment, it reacts to clicking with the left mouse button by trying to
215move the text cursor to this position. It does so by generating as many
216cursor-left or cursor-right keypresses as required (the this only works
217for programs that correctly support wide characters).
218</dd>
219<dd>
220<p>To avoid too many false positives, this is only done when:</p>
221</dd>
222<dl>
223<dt><strong><a name="item__2d_the_tty_is_in_icanon_state_2e">- the tty is in ICANON state.</a></strong><br />
224</dt>
225<dt><strong><a name="item__2d_the_text_cursor_is_visible_2e">- the text cursor is visible.</a></strong><br />
226</dt>
227<dt><strong><a name="item__2d_the_primary_screen_is_currently_being_displaye">- the primary screen is currently being displayed.</a></strong><br />
228</dt>
229<dt><strong><a name="item_same">- the mouse is on the same (multi-row-) line as the text cursor.</a></strong><br />
230</dt>
231</dl>
232<p>The normal selection mechanism isn't disabled, so quick successive clicks
233might interfere with selection creation in harmless ways.</p>
234<dt><strong><a name="item_selection_2dautotransform">selection-autotransform</a></strong><br />
235</dt>
236<dd>
237This selection allows you to do automatic transforms on a selection
238whenever a selection is made.
239</dd>
240<dd>
241<p>It works by specifying perl snippets (most useful is a single <code>s///</code>
242operator) that modify <code>$_</code> as resources:</p>
243</dd>
244<dd>
245<pre>
246 URxvt.selection-autotransform.0: transform
247 URxvt.selection-autotransform.1: transform
248 ...</pre>
249</dd>
250<dd>
251<p>For example, the following will transform selections of the form
252<code>filename:number</code>, often seen in compiler messages, into <code>vi +$filename
253$word</code>:</p>
254</dd>
255<dd>
256<pre>
257 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/</pre>
258</dd>
259<dd>
260<p>And this example matches the same,but replaces it with vi-commands you can
261paste directly into your (vi :) editor:</p>
262</dd>
263<dd>
264<pre>
265 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/</pre>
266</dd>
267<dd>
268<p>Of course, this can be modified to suit your needs and your editor :)</p>
269</dd>
270<dd>
271<p>To expand the example above to typical perl error messages (``XXX at
272FILENAME line YYY.''), you need a slightly more elaborate solution:</p>
273</dd>
274<dd>
275<pre>
276 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
277 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/</pre>
278</dd>
279<dd>
280<p>The first line tells the selection code to treat the unchanging part of
281every error message as a selection pattern, and the second line transforms
282the message into vi commands to load the file.</p>
283</dd>
284<p></p>
285<dt><strong><a name="item_tabbed">tabbed</a></strong><br />
286</dt>
287<dd>
288This transforms the terminal into a tabbar with additional terminals, that
289is, it implements what is commonly refered to as ``tabbed terminal''. The topmost line
290displays a ``[NEW]'' button, which, when clicked, will add a new tab, followed by one
291button per tab.
292</dd>
293<dd>
294<p>Clicking a button will activate that tab. Pressing <strong>Shift-Left</strong> and
295<strong>Shift-Right</strong> will switch to the tab left or right of the current one,
296while <strong>Shift-Down</strong> creates a new tab.</p>
297</dd>
298<dd>
299<p>The tabbar itself can be configured similarly to a normal terminal, but
300with a resource class of <code>URxvt.tabbed</code>. In addition, it supports the
301following four resources (shown with defaults):</p>
302</dd>
303<dd>
304<pre>
305 URxvt.tabbed.tabbar-fg: &lt;colour-index, default 3&gt;
306 URxvt.tabbed.tabbar-bg: &lt;colour-index, default 0&gt;
307 URxvt.tabbed.tab-fg: &lt;colour-index, default 0&gt;
308 URxvt.tabbed.tab-bg: &lt;colour-index, default 1&gt;</pre>
309</dd>
310<dd>
311<p>See <em>COLOR AND GRAPHICS</em> in the <code>rxvt(1)</code> manpage for valid
312indices.</p>
313</dd>
314<p></p>
315<dt><strong><a name="item_mark_2durls">mark-urls</a></strong><br />
316</dt>
317<dd>
318Uses per-line display filtering (<code>on_line_update</code>) to underline urls and
319make them clickable. When middle-clicked, the program specified in the
320resource <code>urlLauncher</code> (default <code>x-www-browser</code>) will be started with
321the URL as first argument.
322</dd>
323<p></p>
324<dt><strong><a name="item_xim_2donthespot">xim-onthespot</a></strong><br />
325</dt>
326<dd>
327This (experimental) perl extension implements OnTheSpot editing. It does
328not work perfectly, and some input methods don't seem to work well with
329OnTheSpot editing in general, but it seems to work at leats for SCIM and
330kinput2.
331</dd>
332<dd>
333<p>You enable it by specifying this extension and a preedit style of
334<code>OnTheSpot</code>, i.e.:</p>
335</dd>
336<dd>
337<pre>
338 rxvt -pt OnTheSpot -pe xim-onthespot</pre>
339</dd>
340<p></p>
341<dt><strong><a name="item_automove_2dbackground">automove-background</a></strong><br />
342</dt>
343<dd>
344This is basically a one-line extension that dynamically changes the background pixmap offset
345to the window position, in effect creating the same effect as pseudo transparency with
346a custom pixmap. No scaling is supported in this mode. Exmaple:
347</dd>
348<dd>
349<pre>
350 rxvt -pixmap background.xpm -pe automove-background</pre>
351</dd>
352<p></p>
353<dt><strong><a name="item_block_2dgraphics_2dto_2dascii">block-graphics-to-ascii</a></strong><br />
354</dt>
355<dd>
356A not very useful example of filtering all text output to the terminal,
357by replacing all line-drawing characters (U+2500 .. U+259F) by a
358similar-looking ascii character.
359</dd>
360<p></p>
96<dt><strong><a name="item_digital_2dclock">digital-clock</a></strong><br /> 361<dt><strong><a name="item_digital_2dclock">digital-clock</a></strong><br />
362</dt>
363<dd>
364Displays a digital clock using the built-in overlay.
365</dd>
366<p></p>
367<dt><strong><a name="item_remote_2dclipboard">remote-clipboard</a></strong><br />
368</dt>
369<dd>
370Somewhat of a misnomer, this extension adds two menu entries to the
371selection popup that allows one ti run external commands to store the
372selection somewhere and fetch it again.
373</dd>
374<dd>
375<p>We use it to implement a ``distributed selection mechanism'', which just
376means that one command uploads the file to a remote server, and another
377reads it.</p>
378</dd>
379<dd>
380<p>The commands can be set using the <code>URxvt.remote-selection.store</code> and
381<code>URxvt.remote-selection.fetch</code> resources. The first should read the
382selection to store from STDIN (always in UTF-8), the second should provide
383the selection data on STDOUT (also in UTF-8).</p>
384</dd>
385<dd>
386<p>The defaults (which are likely useless to you) use rsh and cat:</p>
387</dd>
388<dd>
389<pre>
390 URxvt.remote-selection.store: rsh ruth 'cat &gt;/tmp/distributed-selection'
391 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'</pre>
392</dd>
393<p></p>
394<dt><strong><a name="item_selection_2dpastebin">selection-pastebin</a></strong><br />
395</dt>
396<dd>
397This is a little rarely useful extension that Uploads the selection as
398textfile to a remote site (or does other things). (The implementation is
399not currently secure for use in a multiuser environment as it writes to
400<em>/tmp</em> directly.).
401</dd>
402<dd>
403<p>It listens to the <code>selection-pastebin:remote-pastebin</code> keyboard command,
404i.e.</p>
405</dd>
406<dd>
407<pre>
408 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin</pre>
409</dd>
410<dd>
411<p>Pressing this combination runs a command with <code>%</code> replaced by the name of
412the textfile. This command can be set via a resource:</p>
413</dd>
414<dd>
415<pre>
416 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.</pre>
417</dd>
418<dd>
419<p>And the default is likely not useful to anybody but the few people around
420here :)</p>
421</dd>
422<dd>
423<p>The name of the textfile is the hex encoded md5 sum of the selection, so
424the same content should lead to the same filename.</p>
425</dd>
426<dd>
427<p>After a successful upload the selection will be replaced by the text given
428in the <code>selection-pastebin-url</code> resource (again, the % is the placeholder
429for the filename):</p>
430</dd>
431<dd>
432<pre>

487<h2><a name="extension_objects">Extension Objects</a></h2>
488<p>Very perl extension is a perl class. A separate perl object is created
489for each terminal and each extension and passed as the first parameter to
490hooks. So extensions can use their <code>$self</code> object without having to think
491about other extensions, with the exception of methods and members that
492begin with an underscore character <code>_</code>: these are reserved for internal
493use.</p>
494<p>Although it isn't a <code>urxvt::term</code> object, you can call all methods of the
495<code>urxvt::term</code> class on this object.</p>
