85Intelligent selection. This extension tries to be more intelligent when
86the user extends selections (double-click). Right now, it tries to select

89(More) intelligent selection. This extension tries to be more intelligent
90when the user extends selections (double-click and further clicks). Right
91now, it tries to select words, urls and complete shell-quoted
92arguments, which is very convenient, too, if your <em>ls</em> supports
93<code>--quoting-style=shell</code>.
90<dd> 94</dd>
95<dd>
96<p>A double-click usually selects the word under the cursor, further clicks
97will enlarge the selection.</p>
98</dd>
99<dd>
100<p>The selection works by trying to match a number of regexes and displaying
101them in increasing order of length. You can add your own regexes by
102specifying resources of the form:</p>
103</dd>
104<dd>
105<pre>
106 URxvt.selection.pattern-0: perl-regex
107 URxvt.selection.pattern-1: perl-regex
108 ...</pre>
109</dd>
110<dd>
111<p>The index number (0, 1...) must not have any holes, and each regex must
112contain at least one pair of capturing parentheses, which will be used for
113the match. For example, the followign adds a regex that matches everything
114between two vertical bars:</p>
115</dd>
116<dd>
117<pre>
118 URxvt.selection.pattern-0: \\|([^|]+)\\|</pre>
119</dd>
120<dd>
121<p>You can look at the source of the selection extension to see more
122interesting uses, such as parsing a line from beginning to end.</p>

155<dd>
156Adds regex search functionality to the scrollback buffer, triggered
157by a hotkey (default: <code>M-s</code>). While in search mode, normal terminal
158input/output is suspended and a regex is displayed at the bottom of the
159screen.
160</dd>
161<dd>
162<p>Inputting characters appends them to the regex and continues incremental
163search. <code>BackSpace</code> removes a character from the regex, <code>Up</code> and <code>Down</code>
164search upwards/downwards in the scrollback buffer, <code>End</code> jumps to the
165bottom. <code>Escape</code> leaves search mode and returns to the point where search
166was started, while <code>Enter</code> or <code>Return</code> stay at the current position and
167additionally stores the first match in the current line into the primary
168selection.</p>

172</dt>
173<dd>
174This selection allows you to do automatic transforms on a selection
175whenever a selection is made.
176</dd>
177<dd>
178<p>It works by specifying perl snippets (most useful is a single <code>s///</code>
179operator) that modify <code>$_</code> as resources:</p>
180</dd>
181<dd>
182<pre>
183 URxvt.selection-autotransform.0: transform
184 URxvt.selection-autotransform.1: transform
185 ...</pre>
186</dd>
187<dd>
188<p>For example, the following will transform selections of the form
189<code>filename:number</code>, often seen in compiler messages, into <code>vi +$filename
190$word</code>:</p>
191</dd>
192<dd>
193<pre>
194 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/</pre>
195</dd>
196<dd>
197<p>And this example matches the same,but replaces it with vi-commands you can
198paste directly into your (vi :) editor:</p>
199</dd>
200<dd>
201<pre>
202 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/</pre>
203</dd>
204<dd>
205<p>Of course, this can be modified to suit your needs and your editor :)</p>
206</dd>
207<dd>
208<p>To expand the example above to typical perl error messages (``XXX at
209FILENAME line YYY.''), you need a slightly more elaborate solution:</p>
210</dd>
211<dd>
212<pre>
213 URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
214 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/</pre>
215</dd>
216<dd>
217<p>The first line tells the selection code to treat the unchanging part of
218every error message as a selection pattern, and the second line transforms
219the message into vi commands to load the file.</p>

296<h2><a name="extension_objects">Extension Objects</a></h2>
297<p>Very perl extension is a perl class. A separate perl object is created
298for each terminal and each extension and passed as the first parameter to
299hooks. So extensions can use their <code>$self</code> object without having to think
300about other extensions, with the exception of methods and members that
301begin with an underscore character <code>_</code>: these are reserved for internal
302use.</p>
303<p>Although it isn't a <code>urxvt::term</code> object, you can call all methods of the
304<code>urxvt::term</code> class on this object.</p>
