103<p>A double-click usually selects the word under the cursor, further clicks

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>

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 following 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>

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>

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 referred 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>

352matching a certain pattern and make it clickable. When clicked with the
353mouse button specified in the <code>matcher.button</code> resource (default 2, or
354middle), the program specified in the <code>matcher.launcher</code> resource
355(default, the <code>urlLauncher</code> resource, <code>sensible-browser</code>) will be started
356with the matched text as first argument. The default configuration is
357suitable for matching URLs and launching a web browser, like the
358former ``mark-urls'' extension.</p>
359</dd>
147</dd> 360<dd>
148<p></p> 361<p>The default pattern to match URLs can be overridden with the
362<code>matcher.pattern.0</code> resource, and additional patterns can be specified
363with numbered patterns, in a manner similar to the ``selection'' extension.
364The launcher can also be overridden on a per-pattern basis.</p>
365</dd>
366<dd>
367<p>Example configuration:</p>

382<p>This (experimental) perl extension implements OnTheSpot editing. It does
383not work perfectly, and some input methods don't seem to work well with
384OnTheSpot editing in general, but it seems to work at leats for SCIM and
385kinput2.</p>
386</dd>
387<dd>
388<p>You enable it by specifying this extension and a preedit style of
389<code>OnTheSpot</code>, i.e.:</p>

396<dt><strong><a name="item_kuake_3chotkey_3e">kuake&lt;hotkey&gt;</a></strong>
397
398<dd>
399<p>A very primitive quake-console-like extension. It was inspired by a
400description of how the programs <code>kuake</code> and <code>yakuake</code> work: Whenever the
401user presses a global accelerator key (by default <code>F10</code>), the terminal
402will show or hide itself. Another press of the accelerator key will hide
403or show it again.</p>
404</dd>
405<dd>
406<p>Initially, the window will not be shown when using this extension.</p>
407</dd>
408<dd>
409<p>This is useful if you need a single terminal thats not using any desktop
410space most of the time but is quickly available at the press of a key.</p>
411</dd>
412<dd>
413<p>The accelerator key is grabbed regardless of any modifiers, so this
414extension will actually grab a physical key just for this function.</p>
415</dd>
416<dd>
417<p>If you want a quake-like animation, tell your window manager to do so
418(fvwm can do it).</p>

424<p>This is basically a very small extension that dynamically changes the
425background pixmap offset to the window position, in effect creating the
426same effect as pseudo transparency with a custom pixmap. No scaling is
427supported in this mode. Example:</p>

451<p>Somewhat of a misnomer, this extension adds two menu entries to the

460<dd>
461<p>The commands can be set using the <code>URxvt.remote-selection.store</code> and
462<code>URxvt.remote-selection.fetch</code> resources. The first should read the
