root |
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> |

104 |

<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> |
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> |

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

cursor-left or cursor-right keypresses as required (the this only works |

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

<p>Very perl extension is a perl class. A separate perl object is created |
511 |
|
|
for each terminal and each extension and passed as the first parameter to |
512 |
|
|
hooks. So extensions can use their <code>$self</code> object without having to think |
513 |

|
about other extensions, with the exception of methods and members that |
514 |

begin with an underscore character <code>_</code>: these are reserved for internal |
515 |
|
|
use.</p> |

517 |

<code>urxvt::term</code> class on this object.</p> |
