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>

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>

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>

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 />

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>

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
311textfile to a remote site (or does other things). (The implementation is
312not currently secure for use in a multiuser environment as it writes to
313<em>/tmp</em> directly.).

336<p>The name of the textfile is the hex encoded md5 sum of the selection, so
