<h1><a name="description">DESCRIPTION</a></h1> |
70 |
<p>Everytime a terminal object gets created, extension scripts specified via |
71 |
the <code>perl</code> resource are loaded and associated with it.</p> |
72 |
<p>Scripts are compiled in a 'use strict' and 'use utf8' environment, and |
73 |
thus must be encoded as UTF-8.</p> |
74 |
<p>Each script will only ever be loaded once, even in rxvtd, where |
75 |
scripts will be shared (but not enabled) for all terminals.</p> |
76 |
<p> |

<h1><a name="prepackaged_extensions">PREPACKAGED EXTENSIONS</a></h1> |
80 |
<p>This section describes the extensions delivered with this release. You can |
81 |
find them in <em>/opt/rxvt/lib/urxvt/perl/</em>.</p> |
82 |
<p>You can activate them like this:</p> |
83 |
<pre> |
84 |
rxvt -pe <extensionname></pre> |
85 |
<dl> |
86 |
<dt><strong><a name="item_selection">selection (enabled by default)</a></strong><br /> |
87 |
</dt> |
88 |
<dd> |
89 |
(More) intelligent selection. This extension tries to be more intelligent |
90 |
when the user extends selections (double-click and further clicks). Right |
91 |
now, it tries to select words, urls and complete shell-quoted |
92 |
arguments, which is very convenient, too, if your <em>ls</em> supports |
93 |
<code>--quoting-style=shell</code>. |
94 |
</dd> |
95 |
<dd> |
96 |
<p>A double-click usually selects the word under the cursor, further clicks |
97 |
will enlarge the selection.</p> |
98 |
</dd> |
99 |
<dd> |
100 |
<p>The selection works by trying to match a number of regexes and displaying |
101 |
them in increasing order of length. You can add your own regexes by |
102 |
specifying 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 |
112 |
contain at least one pair of capturing parentheses, which will be used for |
113 |
the match. For example, the followign adds a regex that matches everything |
114 |
between 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 |
122 |
interesting uses, such as parsing a line from beginning to end.</p> |
123 |
</dd> |
124 |
<dd> |
125 |
<p>This extension also offers the following bindable keyboard command:</p> |
126 |
</dd> |
127 |
<dl> |
128 |
<dt><strong><a name="item_rot13">rot13</a></strong><br /> |

131 |
Rot-13 the selection when activated. Used via keyboard trigger: |
132 |

<dt><strong><a name="item_popup">option-popup (enabled by default)</a></strong><br /> |
139 |
</dt> |
140 |
<dd> |
141 |
Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at |
142 |
runtime. |
143 |
</dd> |
144 |
<p></p> |
145 |
<dt><strong>selection-popup (enabled by default)</strong><br /> |
146 |
</dt> |
147 |
<dd> |
148 |
Binds a popup menu to Ctrl-Button3 that lets you convert the selection |
149 |
text into various other formats/action (such as uri unescaping, perl |
150 |
evalution, web-browser starting etc.), depending on content. |
151 |
</dd> |
152 |
<p></p> |
153 |
<dt><strong><a name="item_searchable_2dscrollback_3chotkey_3e__28enabled_by_">searchable-scrollback<hotkey> (enabled by default)</a></strong><br /> |
154 |
</dt> |
155 |
<dd> |
156 |
Adds regex search functionality to the scrollback buffer, triggered |
157 |
by a hotkey (default: <code>M-s</code>). While in search mode, normal terminal |
158 |
input/output is suspended and a regex is displayed at the bottom of the |
159 |
screen. |
160 |
</dd> |
161 |
<dd> |
162 |
<p>Inputting characters appends them to the regex and continues incremental |
163 |
search. <code>BackSpace</code> removes a character from the regex, <code>Up</code> and <code>Down</code> |
164 |
search upwards/downwards in the scrollback buffer, <code>End</code> jumps to the |
165 |
bottom. <code>Escape</code> leaves search mode and returns to the point where search |
166 |
was started, while <code>Enter</code> or <code>Return</code> stay at the current position and |
167 |
additionally stores the first match in the current line into the primary |
168 |
selection.</p> |
169 |
</dd> |
170 |
<p></p> |
171 |
<dt><strong><a name="item_selection_2dautotransform">selection-autotransform</a></strong><br /> |
172 |
</dt> |
173 |
<dd> |
174 |
This selection allows you to do automatic transforms on a selection |
175 |
whenever a selection is made. |
176 |
</dd> |
177 |
<dd> |
178 |
<p>It works by specifying perl snippets (most useful is a single <code>s///</code> |
179 |
operator) 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$1\\E\\x0d/</pre> |
195 |
</dd> |
196 |
<dd> |
197 |
<p>And this example matches the same,but replaces it with vi-commands you can |
198 |
paste directly into your (vi :) editor:</p> |
199 |
</dd> |
200 |
<dd> |
201 |
<pre> |
202 |
URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/</pre> |
203 |
</dd> |
204 |
<dd> |
205 |
<p>Of course, this can be modified to suit your needs and your editor :)</p> |
206 |
</dd> |
207 |
<dd> |
208 |
<p>To expand the example above to typical perl error messages (``XXX at |
209 |
FILENAME line YYY.''), you need a slightly more elaborate solution:</p> |
210 |
</dd> |
211 |
<dd> |
212 |
<pre> |
213 |
URxvt.selection.pattern-0: ( at .*? line \\d+\\.) |
214 |
URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\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 |
218 |
every error message as a selection pattern, and the second line transforms |
219 |
the message into vi commands to load the file.</p> |
220 |
</dd> |
221 |
<p></p> |
222 |
<dt><strong><a name="item_mark_2durls">mark-urls</a></strong><br /> |
223 |
</dt> |
224 |
<dd> |
225 |
Uses per-line display filtering (<code>on_line_update</code>) to underline urls and |
226 |
make them clickable. When middle-clicked, the program specified in the |
227 |
resource <code>urlLauncher</code> (default <code>x-www-browser</code>) will be started with |
228 |
the URL as first argument. |
229 |
</dd> |
230 |
<p></p> |
231 |
<dt><strong><a name="item_block_2dgraphics_2dto_2dascii">block-graphics-to-ascii</a></strong><br /> |
232 |
</dt> |
233 |
<dd> |
234 |
A not very useful example of filtering all text output to the terminal, |
235 |
by replacing all line-drawing characters (U+2500 .. U+259F) by a |
236 |
similar-looking ascii character. |
237 |
</dd> |
238 |
<p></p> |
239 |
<dt><strong><a name="item_digital_2dclock">digital-clock</a></strong><br /> |
240 |
</dt> |
241 |
<dd> |
242 |
Displays a digital clock using the built-in overlay. |

<dt><strong><a name="item_example_2drefresh_2dhooks">example-refresh-hooks</a></strong><br /> |
246 |
</dt> |
247 |
<dd> |
248 |
Displays a very simple digital clock in the upper right corner of the |
249 |

250 |
overlays or changes. |

<p>All objects (such as terminals, time watchers etc.) are typical |
261 |
reference-to-hash objects. The hash can be used to store anything you |
262 |
like. All members starting with an underscore (such as <code>_ptr</code> or |
263 |
<code>_hook</code>) are reserved for internal uses and <strong>MUST NOT</strong> be accessed or |
264 |
modified).</p> |
265 |
<p>When objects are destroyed on the C++ side, the perl object hashes are |
266 |
emptied, so its best to store related objects such as time watchers and |
267 |
the like inside the terminal object so they get destroyed as soon as the |
268 |
terminal is destroyed.</p> |
269 |
<p>Argument names also often indicate the type of a parameter. Here are some |

<h2><a name="extension_objects">Extension Objects</a></h2> |
297 |
<p>Very perl extension is a perl class. A separate perl object is created |
298 |
for each terminal and each extension and passed as the first parameter to |
299 |
hooks. So extensions can use their <code>$self</code> object without having to think |
300 |
about other extensions, with the exception of methods and members that |
301 |
begin with an underscore character <code>_</code>: these are reserved for internal |
302 |
use.</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> |
305 |
<p>It has the following methods and data members:</p> |
306 |
<dl> |

308 |
</dt> |
309 |
<dd> |
310 |
Returns the <code>urxvt::term</code> object associated with this instance of the |
311 |
extension. This member <em>must not</em> be changed in any way. |

315 |
</dt> |
316 |
<dd> |
317 |
Dynamically enable the given hooks (named without the <code>on_</code> prefix) for |
318 |
this extension, replacing any previous hook. This is useful when you want |
319 |

the in the <code>Extension Objects</code> section.</p> |
335 |
<p><strong>All</strong> of these hooks must return a boolean value. If it is true, then the |
336 |
event counts as being <em>consumed</em>, and the invocation of other hooks is |
337 |
skipped, and the relevant action might not be carried out by the C++ code.</p> |

343 |
Called after a new terminal object has been initialized, but before |
344 |
windows are created or the command gets run. Most methods are unsafe to |
345 |
call or deliver senseless data, as terminal size and other characteristics |
