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>

131<dd>
132<pre>
133 URxvt.selection.pattern-0: ^(/[^:]+):\</pre>

137interesting uses, such as parsing a line from beginning to end.</p>

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>

244<dl>

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>

334indices.</p>

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>

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:

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'

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>

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
