67 | hints on what they mean: |

|
|
71 | =item $text |
|
|
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. |
|
|
81 | |
|
|
82 | =item $octets |

|
|
87 | =item $keysym |
|
|
88 | |
|
|
89 | an integer that is a valid X11 keysym code. You can convert a string |
|
|
90 | into a keysym and viceversa by using C<XStringToKeysym> and |
|
|

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 | Additional methods only supported for extension objects are described in |
|
|
109 | the C<urxvt::extension> section below. |

117 | =item on_tty_activity $term *NYI* |
205 | =item on_osc_seq $term, $op, $args, $resp |
118 | |
206 | |
119 | Called whenever the program(s) running in the urxvt window send output. |
207 | Called on every OSC sequence and can be used to suppress it or modify its |
|
|
208 | behaviour. The default should be to return an empty list. A true value |
|
|
209 | suppresses execution of the request completely. Make sure you don't get |
|
|
210 | confused by recursive invocations when you output an OSC sequence within |
|
|
211 | this callback. |
|
|
212 | |
|
|
213 | C<on_osc_seq_perl> should be used for new behaviour. |
|
|
214 | |
|
|
215 | =item on_osc_seq_perl $term, $args, $resp |
|
|
216 | |
|
|
217 | Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC = |
|
|
218 | operating system command) is processed. Cursor position and other state |
|
|
219 | information is up-to-date when this happens. For interoperability, the |
|
|
220 | string should start with the extension name (sans -osc) and a semicolon, |
|
|
221 | to distinguish it from commands for other extensions, and this might be |
|
|
222 | enforced in the future. |
|
|
223 | |
|
|
224 | For example, C<overlay-osc> uses this: |
|
|
225 | |
|
|
226 | sub on_osc_seq_perl { |
|
|
227 | my ($self, $osc, $resp) = @_; |
|
|
228 | |
|
|
229 | return unless $osc =~ s/^overlay;//; |
|
|
230 | |
|
|
231 | ... process remaining $osc string |
|
|
232 | } |
|
|
233 | |
|
|
234 | Be careful not ever to trust (in a security sense) the data you receive, |
|
|
235 | as its source can not easily be controlled (e-mail content, messages from |
|
|
236 | other users on the same system etc.). |
|
|
237 | |
|
|
238 | For responses, C<$resp> contains the end-of-args separator used by the |
|
|
239 | sender. |
|
|
240 | |
|
|
241 | =item on_add_lines $term, $string |
|
|
242 | |
|
|
243 | Called whenever text is about to be output, with the text as argument. You |
|
|
244 | can filter/change and output the text yourself by returning a true value |
|
|
245 | and calling C<< $term->scr_add_lines >> yourself. Please note that this |
|
|
246 | might be very slow, however, as your hook is called for B<all> text being |
|
|
247 | output. |
|
|
248 | |
|
|
249 | =item on_tt_write $term, $octets |
|
|
250 | |
|
|
251 | Called whenever some data is written to the tty/pty and can be used to |
|
|
252 | suppress or filter tty input. |
|
|
253 | |
|
|
254 | =item on_tt_paste $term, $octets |
|
|
255 | |
|
|
256 | Called whenever text is about to be pasted, with the text as argument. You |
|
|
257 | can filter/change and paste the text yourself by returning a true value |
|
|
258 | and calling C<< $term->tt_paste >> yourself. C<$octets> is |
|
|
259 | locale-encoded. |
|
|
260 | |
|
|
261 | =item on_line_update $term, $row |
|
|
262 | |
|
|
263 | Called whenever a line was updated or changed. Can be used to filter |
|
|
264 | screen output (e.g. underline urls or other useless stuff). Only lines |
|
|
265 | that are being shown will be filtered, and, due to performance reasons, |
|
|
266 | not always immediately. |
|
|
267 | |
|
|
268 | The row number is always the topmost row of the line if the line spans |
|
|
269 | multiple rows. |
|
|
270 | |
|
|
271 | Please note that, if you change the line, then the hook might get called |
|
|
272 | later with the already-modified line (e.g. if unrelated parts change), so |
|
|
273 | you cannot just toggle rendition bits, but only set them. |

|
|
286 | =item on_user_command $term, $string |
|
|
287 | |
|
|
288 | Called whenever a user-configured event is being activated (e.g. via |
|
|
289 | a C<perl:string> action bound to a key, see description of the B<keysym> |
|
|
290 | resource in the @@RXVT_NAME@@(1) manpage). |
|
|
291 | |
|
|
292 | The event is simply the action string. This interface is assumed to change |
|
|
293 | slightly in the future. |

|
294 | |
|
|
295 | =item on_register_command $term, $keysym, $modifiermask, $string |
|
|
296 | |
|
|
297 | Called after parsing a keysym resource but before registering the |
|
|
298 | associated binding. If this hook returns TRUE the binding is not |
|
|
299 | registered. It can be used to modify a binding by calling |
|
|
300 | C<register_command>. |
|
|
301 | |
|
|
302 | =item on_resize_all_windows $term, $new_width, $new_height |
|
|
303 | |
|
|
304 | Called just after the new window size has been calculated, but before |
|
|
305 | windows are actually being resized or hints are being set. If this hook |
|
|
306 | returns TRUE, setting of the window hints is being skipped. |
|
|
307 | |
|
|
308 | =item on_x_event $term, $event |
|
|
309 | |
|
|
310 | Called on every X event received on the vt window (and possibly other |
|
|
311 | windows). Should only be used as a last resort. Most event structure |
|
|
312 | members are not passed. |
|
|
313 | |
|
|
314 | =item on_root_event $term, $event |
|

316 | Like C<on_x_event>, but is called for events on the root window. |
|
|
317 | |
|
|
318 | =item on_focus_in $term |
|
|
319 | |
|
|

1230 | |
|

1231 | If the method is called on an extension object (basically, from an |

1232 | extension), then the special prefix C<%.> will be replaced by the name of |

1233 | the extension and a dot, and the lone string C<%> will be replaced by the |

1236 | without having to change the actual code. |

1583 | =item $term->want_refresh |
|

1584 | |
|
|
1585 | Requests a screen refresh. At the next opportunity, rxvt-unicode will |
|
|
1586 | compare the on-screen display with its stored representation. If they |
|
|
1587 | differ, it redraws the differences. |
|
|
1588 | |

|
|
1591 | =item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]]) |
|
|
1592 | |
|
|
1593 | Returns the text of the entire row with number C<$row_number>. Row C<< $term->top_row >> |
|
|
1594 | is the topmost terminal line, row C<< $term->nrow-1 >> is the bottommost |
|
|
1595 | terminal line. Nothing will be returned if a nonexistent line |
|
|
1596 | is requested. |
|
|
1597 | |
|
|
1598 | If C<$new_text> is specified, it will replace characters in the current |
|
|
1599 | line, starting at column C<$start_col> (default C<0>), which is useful |
|
|
1600 | to replace only parts of a line. The font index in the rendition will |
|
|
1601 | automatically be updated. |
|
|
1602 | |
|
|
1603 | C<$text> is in a special encoding: tabs and wide characters that use more |
|
|
1604 | than one cell when displayed are padded with C<$urxvt::NOCHAR> (chr 65535) |
|
|
1605 | characters. Characters with combining characters and other characters that |
|
|
1606 | do not fit into the normal text encoding will be replaced with characters |
|
|
1607 | in the private use area. |
|
|
1608 | |
|
|
1609 | You have to obey this encoding when changing text. The advantage is |
|
|
1610 | that C<substr> and similar functions work on screen cells and not on |
|
|
1611 | characters. |
|
|
1612 | |
|
|
1613 | The methods C<< $term->special_encode >> and C<< $term->special_decode >> |
|
|
1614 | can be used to convert normal strings into this encoding and vice versa. |
|
|
1615 | |
|
|
1616 | =item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]]) |
|
|
1617 | |
|
|
1618 | Like C<< $term->ROW_t >>, but returns an arrayref with rendition |
|
|
1619 | bitsets. Rendition bitsets contain information about colour, font, font |
|
|
1620 | styles and similar information. See also C<< $term->ROW_t >>. |
|
|
1621 | |
|
|
1622 | When setting rendition, the font mask will be ignored. |
|
|
1623 | |

|
|
1626 | =item $length = $term->ROW_l ($row_number[, $new_length]) |
|
|
1627 | |
|
|
1628 | Returns the number of screen cells that are in use ("the line |
|
|
1629 | length"). Unlike the urxvt core, this returns C<< $term->ncol >> if the |
|
|
1630 | line is joined with the following one. |

1631 | |
|
|
1632 | =item $bool = $term->is_longer ($row_number) |

1633 | |
|
|
1634 | Returns true if the row is part of a multiple-row logical "line" (i.e. |
|
|
1635 | joined with the following row), which means all characters are in use |
|
|
1636 | and it is continued on the next row (and possibly a continuation of the |

|
|
1664 | |
|
|
1665 | =item $offset = $line->offset_of ($row, $col) |
|
|
1666 | |
|
|
1667 | Returns the character offset of the given row|col pair within the logical |
|
|
1668 | line. Works for rows outside the line, too, and returns corresponding |
|
|
1669 | offsets outside the string. |
