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>.
82<dd> 94</dd>
83Miscellaneous selection modifications. 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>
123</dd>

175Binds a popup menu to Ctrl-Button3 that lets you convert the selection

177evalution, web-browser starting etc.), depending on content.

181</dt>
182<dd>
183Adds regex search functionality to the scrollback buffer, triggered
184by a hotkey (default: <code>M-s</code>). While in search mode, normal terminal
185input/output is suspended and a regex is displayed at the bottom of the
186screen.
187</dd>
188<dd>
189<p>Inputting characters appends them to the regex and continues incremental
190search. <code>BackSpace</code> removes a character from the regex, <code>Up</code> and <code>Down</code>
191search upwards/downwards in the scrollback buffer, <code>End</code> jumps to the
192bottom. <code>Escape</code> leaves search mode and returns to the point where search
193was started, while <code>Enter</code> or <code>Return</code> stay at the current position and
194additionally stores the first match in the current line into the primary
195selection.</p>

197<p></p>
198<dt><strong><a name="item_selection_2dautotransform">selection-autotransform</a></strong><br />
199</dt>
200<dd>
201This selection allows you to do automatic transforms on a selection
202whenever a selection is made.
203</dd>
204<dd>
205<p>It works by specifying perl snippets (most useful is a single <code>s///</code>
206operator) that modify <code>$_</code> as resources:</p>
207</dd>
208<dd>
209<pre>
210 URxvt.selection-autotransform.0: transform
211 URxvt.selection-autotransform.1: transform
212 ...</pre>
213</dd>
214<dd>
215<p>For example, the following will transform selections of the form
216<code>filename:number</code>, often seen in compiler messages, into <code>vi +$filename
217$word</code>:</p>
218</dd>
219<dd>
220<pre>
221 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/</pre>
222</dd>
223<dd>
224<p>And this example matches the same,but replaces it with vi-commands you can
225paste directly into your (vi :) editor:</p>
226</dd>
227<dd>
228<pre>
229 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/</pre>
230</dd>
231<dd>
232<p>Of course, this can be modified to suit your needs and your editor :)</p>
233</dd>
234<dd>
235<p>To expand the example above to typical perl error messages (``XXX at
236FILENAME line YYY.''), you need a slightly more elaborate solution:</p>
237</dd>
238<dd>
239<pre>
240 URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
241 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/</pre>
242</dd>
243<dd>
244<p>The first line tells the selection code to treat the unchanging part of
245every error message as a selection pattern, and the second line transforms
246the message into vi commands to load the file.</p>
247</dd>
248<p></p>
249<dt><strong><a name="item_mark_2durls">mark-urls</a></strong><br />
250</dt>
251<dd>
252Uses per-line display filtering (<code>on_line_update</code>) to underline urls and
253make them clickable. When middle-clicked, the program specified in the
254resource <code>urlLauncher</code> (default <code>x-www-browser</code>) will be started with
255the URL as first argument.

258<dt><strong><a name="item_block_2dgraphics_2dto_2dascii">block-graphics-to-ascii</a></strong><br />
259</dt>
260<dd>
261A not very useful example of filtering all text output to the terminal,
262by replacing all line-drawing characters (U+2500 .. U+259F) by a
263similar-looking ascii character.

324<p>Very perl extension is a perl class. A separate perl object is created
325for each terminal and each extension and passed as the first parameter to
326hooks. So extensions can use their <code>$self</code> object without having to think
327about other extensions, with the exception of methods and members that
328begin with an underscore character <code>_</code>: these are reserved for internal
329use.</p>
330<p>Although it isn't a <code>urxvt::term</code> object, you can call all methods of the
331<code>urxvt::term</code> class on this object.</p>
