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

96<p>(More) intelligent selection. This extension tries to be more intelligent
97when the user extends selections (double-click and further clicks). Right
98now, it tries to select words, urls and complete shell-quoted
99arguments, which is very convenient, too, if your <em>ls</em> supports
100<code>--quoting-style=shell</code>.</p>
91<dd> 101</dd>
92<p>It also offers the following bindable event:</p> 102<dd>
103<p>A double-click usually selects the word under the cursor, further clicks
104will enlarge the selection.</p>
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>
112<pre>
113 URxvt.selection.pattern-0: perl-regex
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 followign 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>
132</dd>
133<dd>
134<pre>
135 URxvt.selection.pattern-0: ^(/[^:]+):\</pre>
136</dd>
137<dd>
138<p>You can look at the source of the selection extension to see more
139interesting uses, such as parsing a line from beginning to end.</p>

196</dd>
197<dd>
198<p>It's sole argument is the popup menu, which can be modified. The selection
199is in <code>$_</code>, which can be used to decide wether to add something or not.
200It should either return nothing or a string and a code reference. The
201string will be used as button text and the code reference will be called
202when the button gets activated and should transform <code>$_</code>.</p>

218
219<dd>
220<p>Adds regex search functionality to the scrollback buffer, triggered
221by a hotkey (default: <code>M-s</code>). While in search mode, normal terminal
222input/output is suspended and a regex is displayed at the bottom of the
223screen.</p>
224</dd>
225<dd>
226<p>Inputting characters appends them to the regex and continues incremental
227search. <code>BackSpace</code> removes a character from the regex, <code>Up</code> and <code>Down</code>
228search upwards/downwards in the scrollback buffer, <code>End</code> jumps to the
229bottom. <code>Escape</code> leaves search mode and returns to the point where search
230was started, while <code>Enter</code> or <code>Return</code> stay at the current position and
231additionally stores the first match in the current line into the primary
232selection.</p>
233</dd>
234<dd>
235<p>The regex defaults to ``(?i)'', resulting in a case-insensitive search. To
236get a case-sensitive search you can delete this prefix using <code>BackSpace</code>
237or simply use an uppercase character which removes the ``(?i)'' prefix.</p>
238</dd>
239<dd>
240<p>See <em>perlre</em> for more info about perl regular expression syntax.</p>
241</dd>
242</li>
243<dt><strong><a name="item_readline">readline (enabled by default)</a></strong>
244
245<dd>
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>
254</dd>
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 refered 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>

354the URL as first argument.</p>

358
129</dd> 359<dd>
130<p></p> 360<p>This (experimental) perl extension implements OnTheSpot editing. It does
361not work perfectly, and some input methods don't seem to work well with
362OnTheSpot editing in general, but it seems to work at leats for SCIM and
363kinput2.</p>
364</dd>
365<dd>
366<p>You enable it by specifying this extension and a preedit style of
367<code>OnTheSpot</code>, i.e.:</p>
368</dd>
369<dd>
370<pre>

375
376<dd>
377<p>This is basically a very small extension that dynamically changes the
378background pixmap offset to the window position, in effect creating the
379same effect as pseudo transparency with a custom pixmap. No scaling is
380supported in this mode. Exmaple:</p>

401<dt><strong><a name="item_remote_2dclipboard">remote-clipboard</a></strong>
402
403<dd>
404<p>Somewhat of a misnomer, this extension adds two menu entries to the
405selection popup that allows one ti run external commands to store the
406selection somewhere and fetch it again.</p>
407</dd>
408<dd>
409<p>We use it to implement a ``distributed selection mechanism'', which just
410means that one command uploads the file to a remote server, and another
411reads it.</p>
412</dd>
413<dd>
414<p>The commands can be set using the <code>URxvt.remote-selection.store</code> and
415<code>URxvt.remote-selection.fetch</code> resources. The first should read the
416selection to store from STDIN (always in UTF-8), the second should provide
417the selection data on STDOUT (also in UTF-8).</p>
418</dd>
419<dd>
420<p>The defaults (which are likely useless to you) use rsh and cat:</p>
421</dd>
422<dd>
423<pre>
424 URxvt.remote-selection.store: rsh ruth 'cat &gt;/tmp/distributed-selection'

524<p>Every perl extension is a perl class. A separate perl object is created
525for each terminal and each extension and passed as the first parameter to
526hooks. So extensions can use their <code>$self</code> object without having to think
527about other extensions, with the exception of methods and members that
528begin with an underscore character <code>_</code>: these are reserved for internal
529use.</p>
