84Intelligent selection. This extension tries to be more intelligent when
85the user extends selections (double-click). Right now, it tries to select
86urls and complete shell-quoted arguments, which is very convenient, too,
87if your <em>ls</em> supports <code>--quoting-style=shell</code>.

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>.
89<dd> 99</dd>
90<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>You can look at the source of the selection extension to see more
127interesting uses, such as parsing a line from beginning to end.</p>
128</dd>
129<dd>
130<p>This extension also offers following bindable keyboard commands:</p>

153Binds a popup menu to Ctrl-Button3 that lets you convert the selection
154text into various other formats/action (such as uri unescaping, perl
155evalution, web-browser starting etc.), depending on content.
156</dd>
157<dd>
158<p>Other extensions can extend this popup menu by pushing a code reference
159onto <code>@{ $term-</code>{selection_popup_hook} }&gt;, that is called whenever the
160popup is displayed.</p>
161</dd>
162<dd>
163<p>It's sole argument is the popup menu, which can be modified. The selection
164is in <code>$_</code>, which can be used to decide wether to add something or not.
165It should either return nothing or a string and a code reference. The
166string will be used as button text and the code reference will be called
167when the button gets activated and should transform <code>$_</code>.</p>
168</dd>
169<dd>
170<p>The following will add an entry <code>a to b</code> that transforms all <code>a</code>s in
171the selection to <code>b</code>s, but only if the selection currently contains any
172<code>a</code>s:</p>
173</dd>
174<dd>
175<pre>

183</dt>
184<dd>
185Adds regex search functionality to the scrollback buffer, triggered
186by a hotkey (default: <code>M-s</code>). While in search mode, normal terminal
187input/output is suspended and a regex is displayed at the bottom of the
188screen.
189</dd>
190<dd>
191<p>Inputting characters appends them to the regex and continues incremental
192search. <code>BackSpace</code> removes a character from the regex, <code>Up</code> and <code>Down</code>
193search upwards/downwards in the scrollback buffer, <code>End</code> jumps to the
194bottom. <code>Escape</code> leaves search mode and returns to the point where search
195was started, while <code>Enter</code> or <code>Return</code> stay at the current position and
196additionally stores the first match in the current line into the primary
197selection.</p>
198</dd>
199<p></p>
200<dt><strong><a name="item_selection_2dautotransform">selection-autotransform</a></strong><br />
201</dt>
202<dd>
203This selection allows you to do automatic transforms on a selection
204whenever a selection is made.
205</dd>
206<dd>
207<p>It works by specifying perl snippets (most useful is a single <code>s///</code>
208operator) that modify <code>$_</code> as resources:</p>
209</dd>
210<dd>
211<pre>
212 URxvt.selection-autotransform.0: transform
213 URxvt.selection-autotransform.1: transform
214 ...</pre>
215</dd>
216<dd>
217<p>For example, the following will transform selections of the form
218<code>filename:number</code>, often seen in compiler messages, into <code>vi +$filename
219$word</code>:</p>
220</dd>
221<dd>
222<pre>
223 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/</pre>
224</dd>
225<dd>
226<p>And this example matches the same,but replaces it with vi-commands you can
227paste directly into your (vi :) editor:</p>
228</dd>
229<dd>
230<pre>
231 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/</pre>
232</dd>
233<dd>
234<p>Of course, this can be modified to suit your needs and your editor :)</p>
235</dd>
236<dd>
237<p>To expand the example above to typical perl error messages (``XXX at
238FILENAME line YYY.''), you need a slightly more elaborate solution:</p>
239</dd>
240<dd>
241<pre>
242 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
243 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/</pre>
244</dd>
245<dd>
246<p>The first line tells the selection code to treat the unchanging part of
247every error message as a selection pattern, and the second line transforms
248the message into vi commands to load the file.</p>
249</dd>
250<p></p>
251<dt><strong><a name="item_tabbed">tabbed</a></strong><br />
252</dt>
253<dd>
254This transforms the terminal into a tabbar with additional terminals, that
255is, it implements what is commonly refered to as ``tabbed terminal''. The topmost line
256displays a ``[NEW]'' button, which, when clicked, will add a new tab, followed by one
257button per tab.
258</dd>
259<dd>
260<p>Clicking a button will activate that tab. Pressing Shift-Left and
261Shift-Right will switch to the tab left or right of the current one.</p>
107</dd> 262</dd>
108<p></p> 263<p></p>
109<dt><strong><a name="item_mark_2durls">mark-urls</a></strong><br /> 264<dt><strong><a name="item_mark_2durls">mark-urls</a></strong><br />

268make them clickable. When middle-clicked, the program specified in the
269resource <code>urlLauncher</code> (default <code>x-www-browser</code>) will be started with
270the URL as first argument.

273<dt><strong><a name="item_automove_2dbackground">automove-background</a></strong><br />

275<dd>
276This is basically a one-line extension that dynamically changes the background pixmap offset
277to the window position, in effect creating the same effect as pseudo transparency with
278a custom pixmap. No scaling is supported in this mode. Exmaple:

310This is a little rarely useful extension that Uploads the selection as

393<p>Very perl extension is a perl class. A separate perl object is created
394for each terminal and each extension and passed as the first parameter to
395hooks. So extensions can use their <code>$self</code> object without having to think
396about other extensions, with the exception of methods and members that
397begin with an underscore character <code>_</code>: these are reserved for internal
398use.</p>
399<p>Although it isn't a <code>urxvt::term</code> object, you can call all methods of the
400<code>urxvt::term</code> class on this object.</p>
401<p>It has the following methods and data members:</p>

856<p>The sole purpose of this class is to deliver an interface to the
857<code>AnyEvent</code> module - any module using it will work inside urxvt without
858further programming. The only exception is that you cannot wait on
859condition variables, but non-blocking condvar use is ok. What this means
860is that you cannot use blocking APIs, but the non-blocking variant should
861work.</p>
