|
|
72 | |
|
|
73 | Rxvt-unicode's special way of encoding text, where one "unicode" character |
|
|
74 | always represents one screen cell. See L<ROW_t> for a discussion of this format. |
|
|
75 | |
|
|
76 | =item $string |
|
|
77 | |
|
|
78 | A perl text string, with an emphasis on I<text>. It can store all unicode |
|
|
79 | characters and is to be distinguished with text encoded in a specific |
|
|
80 | encoding (often locale-specific) and binary data. |

95 | =head2 Extension Objects |
|
|
96 | |
|
|
97 | Every perl extension is a perl class. A separate perl object is created |
|
|
98 | for each terminal, and each terminal has its own set of extension objects, |
|
|
99 | which are passed as the first parameter to hooks. So extensions can use |
|
|
100 | their C<$self> object without having to think about clashes with other |
|
|
101 | extensions or other terminals, with the exception of methods and members |
|
|
102 | that begin with an underscore character C<_>: these are reserved for |
|
|
103 | internal use. |
|
|
104 | |
|
|
105 | Although it isn't a C<urxvt::term> object, you can call all methods of the |
|
|
106 | C<urxvt::term> class on this object. |
|
|
107 | |
|
|
108 | It has the following methods and data members: |

|

115 | extension. This member I<must not> be changed in any way. |

116 | |
|
|
117 | =item $self->enable ($hook_name => $cb, [$hook_name => $cb..]) |
|
|
118 | |
|
|
119 | Dynamically enable the given hooks (named without the C<on_> prefix) for |
|
|
120 | this extension, replacing any previous hook. This is useful when you want |
|
|
121 | to overwrite time-critical hooks only temporarily. |

|
|
123 | =item $self->disable ($hook_name[, $hook_name..]) |

225 | Called on every OSC sequence and can be used to suppress it or modify its |

236 | operating system command) is processed. Cursor position and other state |
|
|
237 | information is up-to-date when this happens. For interoperability, the |
|
|
238 | string should start with the extension name (sans -osc) and a semicolon, |
|
|
239 | to distinguish it from commands for other extensions, and this might be |
|
|
240 | enforced in the future. |
|
|
241 | |

245 | my ($self, $osc, $resp) = @_; |

252 | Be careful not ever to trust (in a security sense) the data you receive, |

|
253 | as its source can not easily be controlled (e-mail content, messages from |
|
|
254 | other users on the same system etc.). |

|

284 | not always immediately. |
|
|
285 | |
|

288 | |
|
|
289 | Please note that, if you change the line, then the hook might get called |

320 | =item on_resize_all_windows $term, $new_width, $new_height |
|
|
321 | |
|
|
322 | Called just after the new window size has been calculated, but before |
|
|
323 | windows are actually being resized or hints are being set. If this hook |
|
|
324 | returns TRUE, setting of the window hints is being skipped. |

325 | |
|
|
326 | =item on_x_event $term, $event |
|
|
327 | |
|
|
328 | Called on every X event received on the vt window (and possibly other |
|
|
329 | windows). Should only be used as a last resort. Most event structure |
|
|
330 | members are not passed. |

|
|
335 | |
|
|
336 | =item on_focus_in $term |
|
|
337 | |
|
|
338 | Called whenever the window gets the keyboard focus, before rxvt-unicode |
|
|
339 | does focus in processing. |
|
|
340 | |
|
|
341 | =item on_focus_out $term |
|
|
342 | |
|

343 | Called whenever the window loses keyboard focus, before rxvt-unicode does |

344 | focus out processing. |

361 | |
|
|
362 | =item on_unmap_notify $term, $event |
|
|
363 | |
|
|
364 | Called whenever the corresponding X event is received for the terminal. If |
|
|
365 | the hook returns true, then the event will be ignored by rxvt-unicode. |
|
|
366 | |
|
|
367 | The event is a hash with most values as named by Xlib (see the XEvent |
|
|
368 | manpage), with the additional members C<row> and C<col>, which are the |
|
|
369 | (real, not screen-based) row and column under the mouse cursor. |
|
|
370 | |
|
|
371 | C<on_key_press> additionally receives the string rxvt-unicode would |

872 | The sole purpose of this class is to deliver an interface to the |
|
|
873 | C<AnyEvent> module - any module using it will work inside urxvt without |
|
|
874 | further programming. The only exception is that you cannot wait on |
|
|
875 | condition variables, but non-blocking condvar use is ok. |
|
|
876 | |
|
|
877 | In practical terms this means is that you cannot use blocking APIs, but |
|
|
878 | the non-blocking variant should work. |

1043 | C<start> hooks will be called before this call returns, and are free to |

|
|
1152 | class name, i.e. C<< $term->x_resource ("boldFont") >> should return the |
|

1153 | same value as used by this instance of rxvt-unicode. Returns C<undef> if no |
|

1154 | resource with that pattern exists. |
|
|
1155 | |
|
|
1156 | Extensions that define extra resource or command line arguments also need |
|
|
1157 | to call this method to access their values. |
|
|
1158 | |
|
|
1159 | If the method is called on an extension object (basically, from an |
|
|
1160 | extension), then the special prefix C<%.> will be replaced by the name of |
|
|
1161 | the extension and a dot, and the lone string C<%> will be replcaed by the |
|
|
1162 | extension name itself. This makes it possible to code extensions so you |
|
|
1163 | can rename them and get a new set of commandline switches and resources |
|
|
1164 | without having to change the actual code. |
|
|
1165 | |
|
|
1166 | This method should only be called during the C<on_start> hook, as there is |

1168 | the wrong resources. |

|
|
1173 | and returns C<1> for true values, C<0> for false values and C<undef> if |
|

1174 | the resource or option isn't specified. |

2029 | This class implements process watchers. They create an event whenever a |
|
|
2030 | process exits, after which they stop automatically. |
