1.30 |
find them in <em>/opt/rxvt/lib/urxvt/perl/</em>.</p> |

(More) intelligent selection. This extension tries to be more intelligent |
| 95 |
root |
1.25 |
when the user extends selections (double-click and further clicks). Right |
| 96 |
|
|
now, it tries to select words, urls and complete shell-quoted |
| 97 |
|
|
arguments, which is very convenient, too, if your <em>ls</em> supports |
| 98 |
|
|
<code>--quoting-style=shell</code>. |
| 99 |
|
|
</dd> |
| 100 |
|
|
<dd> |
| 101 |
|
|
<p>A double-click usually selects the word under the cursor, further clicks |
| 102 |
|
|
will enlarge the selection.</p> |

</dd> |
| 104 |

<dd> |

<p>The selection works by trying to match a number of regexes and displaying |
| 106 |
|
|
them in increasing order of length. You can add your own regexes by |
| 107 |
|
|
specifying resources of the form:</p> |

</dd> |
| 115 |
|
|
<dd> |
| 116 |
|
|
<p>The index number (0, 1...) must not have any holes, and each regex must |
| 117 |
|
|
contain at least one pair of capturing parentheses, which will be used for |
| 118 |
|
|
the match. For example, the followign adds a regex that matches everything |
| 119 |
|
|
between two vertical bars:</p> |
| 120 |
|
|
</dd> |
| 121 |

<p>Another example: Programs I use often output ``absolute path: '' at the |
| 127 |
|
|
beginning of a line when they process multiple files. The following |

A support package that tries to make editing with readline easier. At the |

moment, it reacts to clicking with the left mouse button by trying to |
| 215 |

move the text cursor to this position. It does so by generating as many |
| 216 |
|
|
cursor-left or cursor-right keypresses as required (the this only works |

for programs that correctly support wide characters). |

This selection allows you to do automatic transforms on a selection |

|
<p>It works by specifying perl snippets (most useful is a single <code>s///</code> |

|
operator) that modify <code>$_</code> as resources:</p> |

| 249 |
|
|
</dd> |
| 250 |
|
|
<dd> |
| 251 |
|
|
<p>For example, the following will transform selections of the form |
| 252 |
|

<code>filename:number</code>, often seen in compiler messages, into <code>vi +$filename |

<p>To expand the example above to typical perl error messages (``XXX at |

<p>The first line tells the selection code to treat the unchanging part of |

every error message as a selection pattern, and the second line transforms |
| 282 |

the message into vi commands to load the file.</p> |

Somewhat of a misnomer, this extension adds two menu entries to the |
| 355 |

selection popup that allows one ti run external commands to store the |

<p>We use it to implement a ``distributed selection mechanism'', which just |
| 360 |

reads it.</p> |
| 362 |

<p>The commands can be set using the <code>URxvt.remote-selection.store</code> and |
| 365 |
|
|
<code>URxvt.remote-selection.fetch</code> resources. The first should read the |
| 366 |
|
|
selection to store from STDIN (always in UTF-8), the second should provide |
| 367 |
|
|
the selection data on STDOUT (also in UTF-8).</p> |

This is a little rarely useful extension that Uploads the selection as |

<p>Very perl extension is a perl class. A separate perl object is created |
| 473 |
|
|
for each terminal and each extension and passed as the first parameter to |
| 474 |
|
|
hooks. So extensions can use their <code>$self</code> object without having to think |
| 475 |
|
|
about other extensions, with the exception of methods and members that |
| 476 |
|
|
begin with an underscore character <code>_</code>: these are reserved for internal |
| 477 |
|
|
use.</p> |
| 478 |
|
|
<p>Although it isn't a <code>urxvt::term</code> object, you can call all methods of the |
| 479 |
|
|
<code>urxvt::term</code> class on this object.</p> |
| 480 |
|

<p>It has the following methods and data members:</p> |

| 484 |

<dd> |
| 485 |

Returns the <code>urxvt::term</code> object associated with this instance of the |

extension. This member <em>must not</em> be changed in any way. |
