84Intelligent selection. This etxension tries to be more intelligent when the user
85extends selections (double-click).
86</dd> 93<dd>
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>.
87<dd> 99</dd>
88<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>

143<dt><strong><a name="item_popup">option-popup (enabled by default)</a></strong><br />
144</dt>
145<dd>
146Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
147runtime.
148</dd>
149<p></p>
150<dt><strong>selection-popup (enabled by default)</strong><br />
151</dt>
152<dd>
153Binds a popup menu to Ctrl-Button3 that lets you convert the selection
154text into various other formats/action (such as uri unescaping, perl
155evaluation, 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>
176 push @{ $self-&gt;{term}{selection_popup_hook} }, sub {
177 /a/ ? (&quot;a to be&quot; =&gt; sub { s/a/b/g }
178 : ()
179 };</pre>

182<dt><strong><a name="item_searchable_2dscrollback_3chotkey_3e__28enabled_by_">searchable-scrollback&lt;hotkey&gt; (enabled by default)</a></strong><br />
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_readline">readline (enabled by default)</a></strong><br />
201</dt>
202<dd>
203A support package that tries to make editing with readline easier. At the
204moment, it reacts to clicking with the left mouse button by trying to
205move the text cursor to this position. It does so by generating as many
206cursor-left or cursor-right keypresses as required (the this only works
207for programs that correctly support wide characters).
208</dd>
209<dd>
210<p>To avoid too many false positives, this is only done when:</p>
211</dd>
212<dl>
213<dt><strong><a name="item__2d_the_tty_is_in_icanon_state_2e">- the tty is in ICANON state.</a></strong><br />
214</dt>
215<dt><strong><a name="item__2d_the_text_cursor_is_visible_2e">- the text cursor is visible.</a></strong><br />
216</dt>
217<dt><strong><a name="item__2d_the_primary_screen_is_currently_being_displaye">- the primary screen is currently being displayed.</a></strong><br />
218</dt>
219<dt><strong><a name="item_same">- the mouse is on the same (multi-row-) line as the text cursor.</a></strong><br />
220</dt>
221</dl>
222<p>The normal selection mechanism isn't disabled, so quick successive clicks
223might interfere with selection creation in harmless ways.</p>
224<dt><strong><a name="item_selection_2dautotransform">selection-autotransform</a></strong><br />
225</dt>
226<dd>
227This selection allows you to do automatic transforms on a selection
228whenever a selection is made.
229</dd>
230<dd>
231<p>It works by specifying perl snippets (most useful is a single <code>s///</code>
232operator) that modify <code>$_</code> as resources:</p>
233</dd>
234<dd>
235<pre>
236 URxvt.selection-autotransform.0: transform
237 URxvt.selection-autotransform.1: transform
238 ...</pre>
239</dd>
240<dd>
241<p>For example, the following will transform selections of the form
242<code>filename:number</code>, often seen in compiler messages, into <code>vi +$filename
243$word</code>:</p>
244</dd>
245<dd>
246<pre>
247 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/</pre>
248</dd>
249<dd>
250<p>And this example matches the same,but replaces it with vi-commands you can
251paste directly into your (vi :) editor:</p>
252</dd>
253<dd>
254<pre>
255 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/</pre>
256</dd>
257<dd>
258<p>Of course, this can be modified to suit your needs and your editor :)</p>
259</dd>
260<dd>
261<p>To expand the example above to typical perl error messages (``XXX at
262FILENAME line YYY.''), you need a slightly more elaborate solution:</p>
263</dd>
264<dd>
265<pre>
266 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
267 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/</pre>
268</dd>
269<dd>
270<p>The first line tells the selection code to treat the unchanging part of
271every error message as a selection pattern, and the second line transforms
272the message into vi commands to load the file.</p>
273</dd>
274<p></p>
275<dt><strong><a name="item_tabbed">tabbed</a></strong><br />
276</dt>
277<dd>
278This transforms the terminal into a tabbar with additional terminals, that
279is, it implements what is commonly refered to as ``tabbed terminal''. The topmost line
280displays a ``[NEW]'' button, which, when clicked, will add a new tab, followed by one
281button per tab.
282</dd>
283<dd>
284<p>Clicking a button will activate that tab. Pressing <strong>Shift-Left</strong> and
285<strong>Shift-Right</strong> will switch to the tab left or right of the current one,
286while <strong>Shift-Down</strong> creates a new tab.</p>
287</dd>
288<p></p>
289<dt><strong><a name="item_mark_2durls">mark-urls</a></strong><br />
290</dt>
291<dd>
292Uses per-line display filtering (<code>on_line_update</code>) to underline urls and
293make them clickable. When middle-clicked, the program specified in the
294resource <code>urlLauncher</code> (default <code>x-www-browser</code>) will be started with
295the URL as first argument.
296</dd>
297<p></p>
298<dt><strong><a name="item_automove_2dbackground">automove-background</a></strong><br />
299</dt>
300<dd>
301This is basically a one-line extension that dynamically changes the background pixmap offset
302to the window position, in effect creating the same effect as pseudo transparency with
303a custom pixmap. No scaling is supported in this mode. Exmaple:
304</dd>
305<dd>
306<pre>
307 rxvt -pixmap background.xpm -pe automove-background</pre>
308</dd>
309<p></p>
310<dt><strong><a name="item_block_2dgraphics_2dto_2dascii">block-graphics-to-ascii</a></strong><br />
311</dt>
312<dd>
313A not very useful example of filtering all text output to the terminal,
314by replacing all line-drawing characters (U+2500 .. U+259F) by a
315similar-looking ascii character.
316</dd>

332<dt><strong><a name="item_selection_2dpastebin">selection-pastebin</a></strong><br />
333</dt>
334<dd>
335This is a little rarely useful extension that Uploads the selection as
336textfile to a remote site (or does other things). (The implementation is
337not currently secure for use in a multiuser environment as it writes to
338<em>/tmp</em> directly.).
339</dd>
340<dd>
341<p>It listens to the <code>selection-pastebin:remote-pastebin</code> keyboard command,
342i.e.</p>
343</dd>
344<dd>
345<pre>
346 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin</pre>
347</dd>
348<dd>
349<p>Pressing this combination runs a command with <code>%</code> replaced by the name of
350the textfile. This command can be set via a resource:</p>
351</dd>
352<dd>
353<pre>
354 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.</pre>
355</dd>
356<dd>
357<p>And the default is likely not useful to anybody but the few people around
358here :)</p>
359</dd>
360<dd>
361<p>The name of the textfile is the hex encoded md5 sum of the selection, so
362the same content should lead to the same filename.</p>
363</dd>
364<dd>
365<p>After a successful upload the selection will be replaced by the text given
366in the <code>selection-pastebin-url</code> resource (again, the % is the placeholder
367for the filename):</p>

417<h2><a name="extension_objects">Extension Objects</a></h2>
418<p>Very perl extension is a perl class. A separate perl object is created
419for each terminal and each extension and passed as the first parameter to
420hooks. So extensions can use their <code>$self</code> object without having to think
421about other extensions, with the exception of methods and members that
422begin with an underscore character <code>_</code>: these are reserved for internal
423use.</p>
424<p>Although it isn't a <code>urxvt::term</code> object, you can call all methods of the
425<code>urxvt::term</code> class on this object.</p>
426<p>It has the following methods and data members:</p>
427<dl>
428<dt><strong><a name="item__24urxvt_term__3d__24self_2d_3e_7bterm_7d">$urxvt_term = $self-&gt;{term}</a></strong><br />
429</dt>
430<dd>
431Returns the <code>urxvt::term</code> object associated with this instance of the
432extension. This member <em>must not</em> be changed in any way.

883<p>The sole purpose of this class is to deliver an interface to the
884<code>AnyEvent</code> module - any module using it will work inside urxvt without
885further programming. The only exception is that you cannot wait on
886condition variables, but non-blocking condvar use is ok. What this means
887is that you cannot use blocking APIs, but the non-blocking variant should
888work.</p>
