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>

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>

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>

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>
141</dd> 297</dd>
142<p></p> 298<p></p>
143<dt><strong><a name="item_mark_2durls">mark-urls</a></strong><br /> 299<dt><strong><a name="item_mark_2durls">mark-urls</a></strong><br />

146Uses per-line display filtering (<code>on_line_update</code>) to underline urls. 302Uses per-line display filtering (<code>on_line_update</code>) to underline urls and
303make them clickable. When middle-clicked, the program specified in the
304resource <code>urlLauncher</code> (default <code>x-www-browser</code>) will be started with
305the URL as first argument.
306</dd>
307<p></p>
308<dt><strong><a name="item_xim_2donthespot">xim-onthespot</a></strong><br />
309</dt>
310<dd>
311This (experimental) perl extension implements OnTheSpot editing. It does
312not work perfectly, and some input methods don't seem to work well with
313OnTheSpot editing in general, but it seems to work at leats for SCIM and
314kinput2.
315</dd>
316<dd>
317<p>You enable it by specifying this extension and a preedit style of
318<code>OnTheSpot</code>, i.e.:</p>
319</dd>
320<dd>
321<pre>
322 rxvt -pt OnTheSpot -pe xim-onthespot</pre>
323</dd>
324<p></p>
325<dt><strong><a name="item_automove_2dbackground">automove-background</a></strong><br />
326</dt>
327<dd>
328This is basically a one-line extension that dynamically changes the background pixmap offset
329to the window position, in effect creating the same effect as pseudo transparency with
330a custom pixmap. No scaling is supported in this mode. Exmaple:
331</dd>

345<dt><strong><a name="item_digital_2dclock">digital-clock</a></strong><br />
346</dt>
347<dd>
348Displays a digital clock using the built-in overlay.

350<p></p>
351<dt><strong><a name="item_remote_2dclipboard">remote-clipboard</a></strong><br />
352</dt>
353<dd>
354Somewhat of a misnomer, this extension adds two menu entries to the
355selection popup that allows one ti run external commands to store the
356selection somewhere and fetch it again.
357</dd>
358<dd>
359<p>We use it to implement a ``distributed selection mechanism'', which just
360means that one command uploads the file to a remote server, and another
361reads it.</p>
362</dd>
363<dd>
364<p>The commands can be set using the <code>URxvt.remote-selection.store</code> and
365<code>URxvt.remote-selection.fetch</code> resources. The first should read the
366selection to store from STDIN (always in UTF-8), the second should provide
367the selection data on STDOUT (also in UTF-8).</p>
368</dd>
369<dd>
370<p>The defaults (which are likely useless to you) use rsh and cat:</p>
371</dd>
372<dd>
373<pre>
374 URxvt.remote-selection.store: rsh ruth 'cat &gt;/tmp/distributed-selection'
375 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'</pre>
376</dd>
377<p></p>
378<dt><strong><a name="item_selection_2dpastebin">selection-pastebin</a></strong><br />
379</dt>
380<dd>
381This is a little rarely useful extension that Uploads the selection as
382textfile to a remote site (or does other things). (The implementation is
383not currently secure for use in a multiuser environment as it writes to
384<em>/tmp</em> directly.).
385</dd>
386<dd>
387<p>It listens to the <code>selection-pastebin:remote-pastebin</code> keyboard command,
388i.e.</p>
389</dd>
390<dd>
391<pre>
392 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin</pre>
393</dd>
394<dd>
395<p>Pressing this combination runs a command with <code>%</code> replaced by the name of
396the textfile. This command can be set via a resource:</p>
397</dd>
398<dd>
399<pre>
400 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.</pre>
401</dd>
402<dd>
403<p>And the default is likely not useful to anybody but the few people around
404here :)</p>
405</dd>
406<dd>
407<p>The name of the textfile is the hex encoded md5 sum of the selection, so
408the same content should lead to the same filename.</p>
409</dd>
410<dd>
411<p>After a successful upload the selection will be replaced by the text given
412in the <code>selection-pastebin-url</code> resource (again, the % is the placeholder
413for the filename):</p>
