<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> |
| 77 |
</p> |
| 78 |
<hr /> |
| 79 |
<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> |

<dl> |
| 128 |
<dt><strong><a name="item_rot13">rot13</a></strong><br /> |

<dt><strong><a name="item_popup">option-popup (enabled by default)</a></strong><br /> |
| 139 |
</dt> |

<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> |

| 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> |

</dt> |

<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 |

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 |
$word</code>:</p> |
| 191 |
</dd> |
| 192 |
<dd> |
| 193 |
<pre> |
| 194 |
URxvt.selection-autotransform.0: s/^(\\S+):(\\d+):?$/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> |

| 203 |
</dd> |

<dt><strong><a name="item_mark_2durls">mark-urls</a></strong><br /> |
| 209 |
</dt> |
| 210 |
<dd> |
| 211 |
Uses per-line display filtering (<code>on_line_update</code>) to underline urls and |
| 212 |
make them clickable. When middle-clicked, the program specified in the |
| 213 |
resource <code>urlLauncher</code> (default <code>x-www-browser</code>) will be started with |
| 214 |
the URL as first argument. |

A not very useful example of filtering all text output to the terminal, |

by replacing all line-drawing characters (U+2500 .. U+259F) by a |

similar-looking ascii character. |

<p>All objects (such as terminals, time watchers etc.) are typical |
| 247 |
reference-to-hash objects. The hash can be used to store anything you |
| 248 |
like. All members starting with an underscore (such as <code>_ptr</code> or |
| 249 |
<code>_hook</code>) are reserved for internal uses and <strong>MUST NOT</strong> be accessed or |
| 250 |
modified).</p> |
| 251 |
<p>When objects are destroyed on the C++ side, the perl object hashes are |
| 252 |
emptied, so its best to store related objects such as time watchers and |
| 253 |
the like inside the terminal object so they get destroyed as soon as the |
| 254 |
terminal is destroyed.</p> |
| 255 |
<p>Argument names also often indicate the type of a parameter. Here are some |

hints on what they mean:</p> |

<h2><a name="extension_objects">Extension Objects</a></h2> |
| 283 |
<p>Very perl extension is a perl class. A separate perl object is created |
| 284 |
for each terminal and each extension and passed as the first parameter to |
| 285 |
hooks. So extensions can use their <code>$self</code> object without having to think |
| 286 |
about other extensions, with the exception of methods and members that |
| 287 |
begin with an underscore character <code>_</code>: these are reserved for internal |
| 288 |
use.</p> |
| 289 |
<p>Although it isn't a <code>urxvt::term</code> object, you can call all methods of the |
| 290 |
<code>urxvt::term</code> class on this object.</p> |
| 291 |
<p>It has the following methods and data members:</p> |
| 292 |
<dl> |

<dt><strong><a name="item__24urxvt_term__3d__24self_2d_3e_7bterm_7d">$urxvt_term = $self->{term}</a></strong><br /> |
| 294 |
</dt> |
| 295 |
<dd> |
| 296 |
Returns the <code>urxvt::term</code> object associated with this instance of the |
| 297 |
extension. This member <em>must not</em> be changed in any way. |

</dt> |
| 302 |
<dd> |
| 303 |
Dynamically enable the given hooks (named without the <code>on_</code> prefix) for |
| 304 |
this extension, replacing any previous hook. This is useful when you want |
| 305 |
to overwrite time-critical hooks only temporarily. |

<p>The following subroutines can be declared in extension files, and will be |

<p>The first argument passed to them is an extension oject as described in |

the in the <code>Extension Objects</code> section.</p> |
| 321 |
<p><strong>All</strong> of these hooks must return a boolean value. If it is true, then the |
| 322 |
event counts as being <em>consumed</em>, and the invocation of other hooks is |
| 323 |
skipped, and the relevant action might not be carried out by the C++ code.</p> |

Called after a new terminal object has been initialized, but before |
