48 | Extensions may add additional resources and C<actions>, i.e., methods |
45 | the user extends selections (double-click). Right now, it tries to select |
49 | which can be bound to a key and invoked by the user. An extension can |
46 | urls and complete shell-quoted arguments, which is very convenient, too, |
50 | define the resources it support using so called META comments, |
47 | if your F<ls> supports C<--quoting-style=shell>. |
51 | described below. Similarly to builtin resources, extension resources |
|
|
52 | can also be specified on the command line as long options (with C<.> |
|
|
53 | replaced by C<->), in which case the corresponding extension is loaded |
|
|
54 | automatically. For this to work the extension B<must> define META |

101 | =head2 Extension Objects |
|
|
102 | |
|
|
103 | Every perl extension is a perl class. A separate perl object is created |
|
|
104 | for each terminal, and each terminal has its own set of extension objects, |
|
|
105 | which are passed as the first parameter to hooks. So extensions can use |
|
|
106 | their C<$self> object without having to think about clashes with other |
|
|
107 | extensions or other terminals, with the exception of methods and members |
|
|
108 | that begin with an underscore character C<_>: these are reserved for |
|
|
109 | internal use. |
|
|
110 | |
|
|
111 | Although it isn't a C<urxvt::term> object, you can call all methods of the |
|
|
112 | C<urxvt::term> class on this object. |
|
|
113 | |
|
|
114 | Additional methods only supported for extension objects are described in |
|
|
115 | the C<urxvt::extension> section below. |
|
|
116 | |
|
|
117 | =head2 META comments |
|
|
118 | |
|
|
119 | Rxvt-unicode recognizes special meta comments in extensions that define |
|
|
120 | different types of metadata. |
|
|
121 | |
|
|
122 | Currently, it recognises only one such comment: |

|

|
|
127 | |
|
|
128 | The RESOURCE comment defines a resource used by the extension, where |
|
|
129 | C<name> is the resource name, C<type> is the resource type, C<boolean> |
|
|
130 | or C<string>, and C<desc> is the resource description. |

1316 | Returns the X-Resource for the given pattern, excluding the program or |
|
|
1317 | class name, i.e. C<< $term->x_resource ("boldFont") >> should return the |
|
|
1318 | same value as used by this instance of rxvt-unicode. Returns C<undef> if no |
|
|
1319 | resource with that pattern exists. |
|
|
1320 | |
|
|
1321 | Extensions that define extra resources also need to call this method |
|
|
1322 | to access their values. |
|
|
1323 | |
|
|
1324 | If the method is called on an extension object (basically, from an |
|
|
1325 | extension), then the special prefix C<%.> will be replaced by the name of |
|
|
1326 | the extension and a dot, and the lone string C<%> will be replaced by the |
|
|
1327 | extension name itself. This makes it possible to code extensions so you |
|
|
1328 | can rename them and get a new set of resources without having to change |
|
|
1329 | the actual code. |
|
|
1330 | |
|
|
1331 | This method should only be called during the C<on_start> hook, as there is |
|
|
1332 | only one resource database per display, and later invocations might return |
|
|
1333 | the wrong resources. |

|
1335 | =item $value = $term->x_resource_boolean ($pattern) |
|
|
1336 | |
|
|
1337 | Like C<x_resource>, above, but interprets the string value as a boolean |
|
|
1338 | and returns C<1> for true values, C<0> for false values and C<undef> if |
|
|
1339 | the resource or option isn't specified. |
|
|
1340 | |
|
|
1341 | You should always use this method to parse boolean resources. |

1358 | Adds a key binding exactly as specified via a C<keysym> resource. See the |
|
|
1359 | C<keysym> resource in the urxvt(1) manpage. |
|
|
1360 | |
|
|
1361 | To add default bindings for actions, an extension should call C<< |
|
|
1362 | ->bind_action >> in its C<init> hook for every such binding. Doing it |
|
|
1363 | in the C<init> hook allows users to override or remove the binding |
|
|
1364 | again. |
|
|
1365 | |
|
|
1366 | Example: the C<searchable-scrollback> by default binds itself |
|
|
1367 | on C<Meta-s>, using C<< $self->bind_action >>, which calls C<< |
|
