85Intelligent selection. This extension tries to be more intelligent when
86the user extends selections (double-click). Right now, it tries to select
87urls and complete shell-quoted arguments, which is very convenient, too,
88if your <em>ls</em> supports <code>--quoting-style=shell</code>.
89</dd> 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>.
90<dd> 99</dd>
91<p>It also offers the following bindable event:</p> 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>

155<dd>
156Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
157runtime.
106<dd> 158</dd>
107Displays a digital clock using the built-in overlay. 159<dd>
160<p>Other extensions can extend this popup menu by pushing a code reference
161onto <code>@{ $term-</code>{option_popup_hook} }&gt;, which gets called whenever the
162popup is being displayed.</p>
163</dd>
164<dd>
165<p>It's sole argument is the popup menu, which can be modified. It should
166either return nothing or a string, the initial boolean value and a code
167reference. The string will be used as button text and the code reference
168will be called when the toggle changes, with the new boolean value as
169first argument.</p>
170</dd>
171<dd>
172<p>The following will add an entry <code>myoption</code> that changes
173<code>$self-</code>{myoption}&gt;:</p>

181<p></p>
182<dt><strong>selection-popup (enabled by default)</strong><br />
183</dt>
184<dd>
185Binds a popup menu to Ctrl-Button3 that lets you convert the selection
186text into various other formats/action (such as uri unescaping, perl
187evaluation, web-browser starting etc.), depending on content.
188</dd>
189<dd>
190<p>Other extensions can extend this popup menu by pushing a code reference
191onto <code>@{ $term-</code>{selection_popup_hook} }&gt;, which gets called whenever the
192popup is being displayed.</p>
193</dd>
194<dd>
195<p>It's sole argument is the popup menu, which can be modified. The selection
196is in <code>$_</code>, which can be used to decide wether to add something or not.
197It should either return nothing or a string and a code reference. The
198string will be used as button text and the code reference will be called
199when the button gets activated and should transform <code>$_</code>.</p>
200</dd>
201<dd>
202<p>The following will add an entry <code>a to b</code> that transforms all <code>a</code>s in
203the selection to <code>b</code>s, but only if the selection currently contains any
204<code>a</code>s:</p>
205</dd>
206<dd>
207<pre>
208 push @{ $self-&gt;{term}{selection_popup_hook} }, sub {
209 /a/ ? (&quot;a to be&quot; =&gt; sub { s/a/b/g }

214<dt><strong><a name="item_searchable_2dscrollback_3chotkey_3e__28enabled_by_">searchable-scrollback&lt;hotkey&gt; (enabled by default)</a></strong><br />
215</dt>
216<dd>
217Adds regex search functionality to the scrollback buffer, triggered
218by a hotkey (default: <code>M-s</code>). While in search mode, normal terminal
219input/output is suspended and a regex is displayed at the bottom of the
220screen.
221</dd>
222<dd>
223<p>Inputting characters appends them to the regex and continues incremental
224search. <code>BackSpace</code> removes a character from the regex, <code>Up</code> and <code>Down</code>
225search upwards/downwards in the scrollback buffer, <code>End</code> jumps to the
226bottom. <code>Escape</code> leaves search mode and returns to the point where search
227was started, while <code>Enter</code> or <code>Return</code> stay at the current position and
228additionally stores the first match in the current line into the primary
229selection.</p>
230</dd>
231<p></p>
232<dt><strong><a name="item_readline">readline (enabled by default)</a></strong><br />
233</dt>
234<dd>
235A support package that tries to make editing with readline easier. At the
236moment, it reacts to clicking with the left mouse button by trying to
237move the text cursor to this position. It does so by generating as many
238cursor-left or cursor-right keypresses as required (the this only works
239for programs that correctly support wide characters).
240</dd>
241<dd>
242<p>To avoid too many false positives, this is only done when:</p>
243</dd>
244<dl>
245<dt><strong><a name="item__2d_the_tty_is_in_icanon_state_2e">- the tty is in ICANON state.</a></strong><br />
246</dt>
247<dt><strong><a name="item__2d_the_text_cursor_is_visible_2e">- the text cursor is visible.</a></strong><br />
248</dt>
249<dt><strong><a name="item__2d_the_primary_screen_is_currently_being_displaye">- the primary screen is currently being displayed.</a></strong><br />
250</dt>
251<dt><strong><a name="item_same">- the mouse is on the same (multi-row-) line as the text cursor.</a></strong><br />
252</dt>
253</dl>
254<p>The normal selection mechanism isn't disabled, so quick successive clicks
255might interfere with selection creation in harmless ways.</p>
256<dt><strong><a name="item_selection_2dautotransform">selection-autotransform</a></strong><br />
257</dt>
258<dd>
259This selection allows you to do automatic transforms on a selection
260whenever a selection is made.
261</dd>
262<dd>
263<p>It works by specifying perl snippets (most useful is a single <code>s///</code>
264operator) that modify <code>$_</code> as resources:</p>
265</dd>
266<dd>
267<pre>
268 URxvt.selection-autotransform.0: transform
269 URxvt.selection-autotransform.1: transform
270 ...</pre>
271</dd>
272<dd>
273<p>For example, the following will transform selections of the form
274<code>filename:number</code>, often seen in compiler messages, into <code>vi +$filename
275$word</code>:</p>
276</dd>
277<dd>
278<pre>
279 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/</pre>
280</dd>
281<dd>
282<p>And this example matches the same,but replaces it with vi-commands you can
283paste directly into your (vi :) editor:</p>
284</dd>
285<dd>
286<pre>
287 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/</pre>
288</dd>
289<dd>
290<p>Of course, this can be modified to suit your needs and your editor :)</p>
291</dd>
292<dd>
293<p>To expand the example above to typical perl error messages (``XXX at
294FILENAME line YYY.''), you need a slightly more elaborate solution:</p>
295</dd>
296<dd>
297<pre>
298 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
299 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/</pre>
300</dd>
301<dd>
302<p>The first line tells the selection code to treat the unchanging part of
303every error message as a selection pattern, and the second line transforms
304the message into vi commands to load the file.</p>
305</dd>
306<p></p>
307<dt><strong><a name="item_tabbed">tabbed</a></strong><br />
308</dt>
309<dd>
310This transforms the terminal into a tabbar with additional terminals, that
311is, it implements what is commonly refered to as ``tabbed terminal''. The topmost line
312displays a ``[NEW]'' button, which, when clicked, will add a new tab, followed by one
313button per tab.
314</dd>
315<dd>
316<p>Clicking a button will activate that tab. Pressing <strong>Shift-Left</strong> and
317<strong>Shift-Right</strong> will switch to the tab left or right of the current one,
318while <strong>Shift-Down</strong> creates a new tab.</p>
319</dd>
320<dd>
321<p>The tabbar itself can be configured similarly to a normal terminal, but
322with a resource class of <code>URxvt.tabbed</code>. In addition, it supports the
323following four resources (shown with defaults):</p>
324</dd>
325<dd>
326<pre>
327 URxvt.tabbed.tabbar-fg: &lt;colour-index, default 3&gt;
328 URxvt.tabbed.tabbar-bg: &lt;colour-index, default 0&gt;
329 URxvt.tabbed.tab-fg: &lt;colour-index, default 0&gt;
330 URxvt.tabbed.tab-bg: &lt;colour-index, default 1&gt;</pre>
331</dd>
332<dd>
333<p>See <em>COLOR AND GRAPHICS</em> in the <code>rxvt(1)</code> manpage for valid
334indices.</p>

113Uses per-line display filtering (<code>on_line_update</code>) to underline urls. 340Uses per-line display filtering (<code>on_line_update</code>) to underline urls and
341make them clickable. When middle-clicked, the program specified in the
342resource <code>urlLauncher</code> (default <code>x-www-browser</code>) will be started with
343the URL as first argument.
344</dd>
345<p></p>
346<dt><strong><a name="item_xim_2donthespot">xim-onthespot</a></strong><br />
347</dt>
348<dd>
349This (experimental) perl extension implements OnTheSpot editing. It does
350not work perfectly, and some input methods don't seem to work well with
351OnTheSpot editing in general, but it seems to work at leats for SCIM and
352kinput2.
353</dd>
354<dd>
355<p>You enable it by specifying this extension and a preedit style of
356<code>OnTheSpot</code>, i.e.:</p>
357</dd>
358<dd>
359<pre>
360 rxvt -pt OnTheSpot -pe xim-onthespot</pre>
361</dd>
362<p></p>
363<dt><strong><a name="item_automove_2dbackground">automove-background</a></strong><br />
364</dt>
365<dd>
366This is basically a one-line extension that dynamically changes the background pixmap offset
367to the window position, in effect creating the same effect as pseudo transparency with
368a custom pixmap. No scaling is supported in this mode. Exmaple:
369</dd>
370<dd>
371<pre>
372 rxvt -pixmap background.xpm -pe automove-background</pre>

383<dt><strong><a name="item_digital_2dclock">digital-clock</a></strong><br />
384</dt>
385<dd>
386Displays a digital clock using the built-in overlay.
387</dd>
388<p></p>
389<dt><strong><a name="item_remote_2dclipboard">remote-clipboard</a></strong><br />
390</dt>
391<dd>
392Somewhat of a misnomer, this extension adds two menu entries to the
393selection popup that allows one ti run external commands to store the
394selection somewhere and fetch it again.
395</dd>
396<dd>
397<p>We use it to implement a ``distributed selection mechanism'', which just
398means that one command uploads the file to a remote server, and another
399reads it.</p>
400</dd>
401<dd>
402<p>The commands can be set using the <code>URxvt.remote-selection.store</code> and
403<code>URxvt.remote-selection.fetch</code> resources. The first should read the
404selection to store from STDIN (always in UTF-8), the second should provide
405the selection data on STDOUT (also in UTF-8).</p>
406</dd>
407<dd>
408<p>The defaults (which are likely useless to you) use rsh and cat:</p>
409</dd>
410<dd>
411<pre>
412 URxvt.remote-selection.store: rsh ruth 'cat &gt;/tmp/distributed-selection'
413 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'</pre>
414</dd>
415<p></p>
416<dt><strong><a name="item_selection_2dpastebin">selection-pastebin</a></strong><br />
417</dt>
418<dd>
419This is a little rarely useful extension that Uploads the selection as
420textfile to a remote site (or does other things). (The implementation is
421not currently secure for use in a multiuser environment as it writes to
422<em>/tmp</em> directly.).
423</dd>
424<dd>
425<p>It listens to the <code>selection-pastebin:remote-pastebin</code> keyboard command,
426i.e.</p>
427</dd>
428<dd>
429<pre>
430 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin</pre>
431</dd>
432<dd>
433<p>Pressing this combination runs a command with <code>%</code> replaced by the name of
434the textfile. This command can be set via a resource:</p>
435</dd>
436<dd>
437<pre>
438 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.</pre>
439</dd>
440<dd>
441<p>And the default is likely not useful to anybody but the few people around
442here :)</p>
443</dd>
444<dd>
445<p>The name of the textfile is the hex encoded md5 sum of the selection, so
446the same content should lead to the same filename.</p>
447</dd>
448<dd>
449<p>After a successful upload the selection will be replaced by the text given
450in the <code>selection-pastebin-url</code> resource (again, the % is the placeholder
451for the filename):</p>
452</dd>

510<p>Very perl extension is a perl class. A separate perl object is created
511for each terminal and each extension and passed as the first parameter to
512hooks. So extensions can use their <code>$self</code> object without having to think
513about other extensions, with the exception of methods and members that
514begin with an underscore character <code>_</code>: these are reserved for internal
515use.</p>
516<p>Although it isn't a <code>urxvt::term</code> object, you can call all methods of the
517<code>urxvt::term</code> class on this object.</p>
