26 | Prepackaged Extensions |
|
|
27 | This section describes the extensiosn delivered with this version. You |
|
|
28 | can find them in /opt/rxvt/lib/urxvt/perl/. |
|
|
29 | |
|
|
30 | You can activate them like this: |
|
|
31 | |
|
|
32 | rxvt -pe <extensionname> |
|
|
33 | |
|
|
34 | selection (enabled by default) |
|
|
35 | Intelligent selection. This extension tries to be more intelligent |
|
|
36 | when the user extends selections (double-click). Right now, it tries |
|
|
37 | to select urls and complete shell-quoted arguments, which is very |
|
|
38 | convenient, too, if your ls supports "--quoting-style=shell". |
|
|
39 | |
|
|
40 | It also offers the following bindable event: |
|
|
41 | |
|
|
42 | rot13 |
|
|
43 | Rot-13 the selection when activated. Used via keyboard trigger: |
|
|
44 | |
|
|
45 | URxvt.keysym.C-M-r: perl:selection:rot13 |
|
|
46 | |
|
|
47 | option-popup (enabled by default) |
|
|
48 | Binds a popup menu to Ctrl-Button2 that lets you toggle (some) |
|
|
49 | options at runtime. |
|
|
50 | |
|
|
51 | selection-popup (enabled by default) |
|
|
52 | Binds a popup menu to Ctrl-Button3 that lets you convert the |
|
|
53 | selection text into various other formats/action. |
|
|
54 | |
|
|
55 | searchable-scrollback<hotkey> (enabled by default) |
|
|
56 | Adds regex search functionality to the scrollback buffer, triggered |
|
|
57 | by a hotkey (default: "M-s"). When in search mode, normal terminal |
|
|
58 | input/output is suspended. |
|
|
59 | |
|
|
60 | "/" starts an incremental regex search, "n" searches further, "p" or |
|
|
61 | "N" jump to the previous match, "G" jumps to the bottom and clears |
|
|
62 | the history, "enter" leaves search mode at the current position and |
|
|
63 | "escape" returns to the original position. |
|
|
64 | |
|
|
65 | digital-clock |
|
|
66 | Displays a digital clock using the built-in overlay. |
|
|
67 | |
|
|
68 | mark-urls |
|
|
69 | Uses per-line display filtering ("on_line_update") to underline |
|
|
70 | urls. |
|
|
71 | |
|
|
72 | block-graphics-to-ascii |
|
|
73 | A not very useful example of filtering all text output to the |
|
|
74 | terminal, by replacing all line-drawing characters (U+2500 .. |
|
|
75 | U+259F) by a similar-looking ascii character. |
|
|
76 | |
|
|
77 | example-refresh-hooks |
|
|
78 | Displays a very simple digital clock in the upper right corner of |
|
|
79 | the window. Illustrates overwriting the refresh callbacks to create |
|
|
80 | your own overlays or changes. |

93 | |
|
|
94 | Argument names also often indicate the type of a parameter. Here are |
|
|
95 | some hints on what they mean: |
|
|
96 | |
|
|
97 | $text |
|
|
98 | Rxvt-unicodes special way of encoding text, where one "unicode" |
|
|
99 | character always represents one screen cell. See row_t for a |
|
|
100 | discussion of this format. |
|
|
101 | |
|
|
102 | $string |
|
|
103 | A perl text string, with an emphasis on *text*. It can store all |
|
|
104 | unicode characters and is to be distinguished with text encoded in a |
|
|
105 | specific encoding (often locale-specific) and binary data. |
|
|
106 | |
|
|
107 | $octets |
|
|
108 | Either binary data or - more common - a text string encoded in a |
|
|
109 | locale-specific way. |
|
|
110 | |
|
|
111 | Extension Objects |
|
|
112 | Very perl extension is a perl class. A separate perl object is created |
|
|
113 | for each terminal and each extension and passed as the first parameter |
|
|
114 | to hooks. So extensions can use their $self object without having to |
|
|
115 | think about other extensions, with the exception of methods and members |
|
|
116 | that begin with an underscore character "_": these are reserved for |
|
|
117 | internal use. |
|
|
118 | |
|
|
119 | Although it isn't a "urxvt::term" object, you can call all methods of |
|
|
120 | the "urxvt::term" class on this object. |
|
|
121 | |
|
|
122 | It has the following methods and data members: |
|
|
123 | |
|
|
124 | $urxvt_term = $self->{term} |
|
|
125 | Returns the "urxvt::term" object associated with this instance of |
|
|
126 | the extension. This member *must not* be changed in any way. |
|
|
127 | |
|
|
128 | $self->enable ($hook_name => $cb, [$hook_name => $cb..]) |
|
|
129 | Dynamically enable the given hooks (named without the "on_" prefix) |
|
|
130 | for this extension, replacing any previous hook. This is useful when |
|
|
131 | you want to overwrite time-critical hooks only temporarily. |
|
|
132 | |
|
|
133 | $self->disable ($hook_name[, $hook_name..]) |
|
|
134 | Dynamically disable the given hooks. |

78 | on_focus_in $term |
183 | on_sel_extend $term |
79 | Called whenever the window gets the keyboard focus, before urxvt |
184 | Called whenever the user tries to extend the selection (e.g. with a |
80 | does focus in processing. |
185 | double click) and is either supposed to return false (normal |
|
|
186 | operation), or should extend the selection itelf and return true to |
|
|
187 | suppress the built-in processing. |
81 | |
188 | |
82 | on_focus_out $term |
189 | See the selection example extension. |
83 | Called wheneever the window loses keyboard focus, before urxvt does |

100 | on_tty_activity $term *NYI* |
205 | on_osc_seq $term, $string |
101 | Called whenever the program(s) running in the urxvt window send |
206 | Called whenever the ESC ] 777 ; string ST command sequence (OSC = |
102 | output. |
207 | operating system command) is processed. Cursor position and other |
|
|
208 | state information is up-to-date when this happens. For |
|
|
209 | interoperability, the string should start with the extension name |
|
|
210 | and a colon, to distinguish it from commands for other extensions, |
|
|
211 | and this might be enforced in the future. |
|
|
212 | |
|
|
213 | Be careful not ever to trust (in a security sense) the data you |
|
|
214 | receive, as its source can not easily be controleld (e-mail content, |
|
|
215 | messages from other users on the same system etc.). |
|
|
216 | |
|
|
217 | on_add_lines $term, $string |
|
|
218 | Called whenever text is about to be output, with the text as |
|
|
219 | argument. You can filter/change and output the text yourself by |
|
|
220 | returning a true value and calling "$term->scr_add_lines" yourself. |
|
|
221 | Please note that this might be very slow, however, as your hook is |
|
|
222 | called for all text being output. |
|
|
223 | |
|
|
224 | on_tt_write $term, $octets |
|
|
225 | Called whenever some data is written to the tty/pty and can be used |
|
|
226 | to suppress or filter tty input. |
|
|
227 | |
|
|
228 | on_line_update $term, $row |
|
|
229 | Called whenever a line was updated or changed. Can be used to filter |
|
|
230 | screen output (e.g. underline urls or other useless stuff). Only |
|
|
231 | lines that are being shown will be filtered, and, due to performance |
|
|
232 | reasons, not always immediately. |
|
|
233 | |
|
|
234 | The row number is always the topmost row of the line if the line |
|
|
235 | spans multiple rows. |
|
|
236 | |
|
|
237 | Please note that, if you change the line, then the hook might get |
|
|
238 | called later with the already-modified line (e.g. if unrelated parts |
|
|
239 | change), so you cannot just toggle rendition bits, but only set |
|
|
240 | them. |
103 | |

|
|
252 | Called whenever the user presses a key combination that has a |
|
|
253 | "perl:string" action bound to it (see description of the keysym |

325 | RENDITION |
|
|
326 | Rendition bitsets contain information about colour, font, font styles |
|
|
327 | and similar information for each screen cell. |
|
|
328 | |
|
|
329 | The following "macros" deal with changes in rendition sets. You should |
|
|
330 | never just create a bitset, you should always modify an existing one, as |
|
|
331 | they contain important information required for correct operation of |
|
|
332 | rxvt-unicode. |
|
|
333 | |
|
|
334 | $rend = urxvt::DEFAULT_RSTYLE |
|
|
335 | Returns the default rendition, as used when the terminal is starting |
|
|
336 | up or being reset. Useful as a base to start when creating |
|
|
337 | renditions. |
|
|
338 | |
|
|
339 | $rend = urxvt::OVERLAY_RSTYLE |
|
|
340 | Return the rendition mask used for overlays by default. |
|
|
341 | |
|
|
342 | $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline |
|
|
343 | Return the bit that enabled bold, italic, blink, reverse-video and |
|
|
344 | underline, respectively. To enable such a style, just logically OR |
|
|
345 | it into the bitset. |

364 | The "urxvt::anyevent" Class |
|
|
365 | The sole purpose of this class is to deliver an interface to the |
|
|
366 | "AnyEvent" module - any module using it will work inside urxvt without |
|
|
367 | further work. The only exception is that you cannot wait on condition |
|
|
368 | variables, but non-blocking condvar use is ok. What this means is that |
|
|
369 | you cannot use blocking APIs, but the non-blocking variant should work. |

195 | |
471 | |
196 | $term->scr_overlay_set ($x, $y, $text) |
472 | $overlay->set ($x, $y, $text, $rend) |
197 | Write a string at the given position into the overlay. |
473 | Similar to "$term->ROW_t" and "$term->ROW_r" in that it puts |
|
|
474 | text in rxvt-unicode's special encoding and an array of |
|
|
475 | rendition values at a specific position inside the overlay. |

499 | $term->scr_xor_span ($beg_row, $beg_col, $end_row, $end_col[, $rstyle]) |
|
|
500 | XORs the rendition values in the given span with the provided value |
|
|
501 | (default: "RS_RVid"). Useful in refresh hooks to provide effects |
|
|
502 | similar to the selection. |

|
504 | $term->scr_xor_rect ($beg_row, $beg_col, $end_row, $end_col[, $rstyle1[, |
|

|
|
506 | Similar to "scr_xor_span", but xors a rectangle instead. Trailing |
|
|
507 | whitespace will additionally be xored with the $rstyle2, which |
|
|
508 | defaults to "RS_RVid | RS_Uline", which removes reverse video again |
|
|
509 | and underlines it instead. |

514 | $term->scr_add_lines ($string) |
|
|
515 | Write the given text string to the screen, as if output by the |
|
|
516 | application running inside the terminal. It may not contain command |
|
|
517 | sequences (escape codes), but is free to use line feeds, carriage |
|
|
518 | returns and tabs. The string is a normal text string, not in |
|
|
519 | locale-dependent encoding. |
|
|
520 | |
|
|
521 | Normally its not a good idea to use this function, as programs might |
|
|
522 | be confused by changes in cursor position or scrolling. Its useful |
|
|
523 | inside a "on_add_lines" hook, though. |
|
|
524 | |
|
|
525 | $term->cmd_parse ($octets) |
|
|
526 | Similar to "scr_add_lines", but the argument must be in the |
|
|
527 | locale-specific encoding of the terminal and can contain command |
|
|
528 | sequences (escape codes) that will be interpreted. |

|
|
537 | Replaces the event mask of the pty watcher by the given event mask. |
|
|
538 | Can be used to suppress input and output handling to the pty/tty. |
|
|
539 | See the description of "urxvt::timer->events". Make sure to always |
|
|
540 | restore the previous value. |

559 | $lines_in_scrollback = $term->nsaved |
|

|
|
561 | |
|
|
562 | $lc_ctype = $term->locale |
|
|
563 | Returns the LC_CTYPE category string used by this rxvt-unicode. |
|
|
564 | |
|
|
565 | $x_display = $term->display_id |
|

568 | $modifiermask = $term->ModLevel3Mask |
|
|
569 | $modifiermask = $term->ModMetaMask |
|
|
570 | $modifiermask = $term->ModNumLockMask |
|
|
571 | Return the modifier masks corresponding to the "ISO Level 3 Shift" |
|
|
572 | (often AltGr), the meta key (often Alt) and the num lock key, if |
|
|
573 | applicable. |
|
|
574 | |
|
|
575 | $view_start = $term->view_start ([$newvalue]) |
|
|
576 | Returns the negative row number of the topmost line. Minimum value |
|
|
577 | is 0, which displays the normal terminal contents. Larger values |
|
|
578 | scroll this many lines into the scrollback buffer. |
|
|
579 | |
|
|
580 | $term->want_refresh |
|
|
581 | Requests a screen refresh. At the next opportunity, rxvt-unicode |
|
|
582 | will compare the on-screen display with its stored representation. |
|
|
583 | If they differ, it redraws the differences. |
|
|
584 | |
|
|
585 | Used after changing terminal contents to display them. |
|
|
586 | |
|
|
587 | $text = $term->ROW_t ($row_number[, $new_text[, $start_col]]) |
|
|
588 | Returns the text of the entire row with number $row_number. Row 0 is |
|
|
589 | the topmost terminal line, row "$term->$ncol-1" is the bottommost |
|
|
590 | terminal line. The scrollback buffer starts at line -1 and extends |
|
|
591 | to line "-$term->nsaved". Nothing will be returned if a nonexistent |
|
|
592 | line is requested. |
|
|
593 | |
|
|
594 | If $new_text is specified, it will replace characters in the current |
|
|
595 | line, starting at column $start_col (default 0), which is useful to |
|
|
596 | replace only parts of a line. The font index in the rendition will |
|
|
597 | automatically be updated. |
|
|
598 | |
|
|
599 | $text is in a special encoding: tabs and wide characters that use |
|
|
600 | more than one cell when displayed are padded with urxvt::NOCHAR |
|
|
601 | characters ("chr 65535"). Characters with combining characters and |
|
|
602 | other characters that do not fit into the normal tetx encoding will |
|
|
603 | be replaced with characters in the private use area. |
|
|
604 | |
|
|
605 | You have to obey this encoding when changing text. The advantage is |
|
|
606 | that "substr" and similar functions work on screen cells and not on |
|
|
607 | characters. |
|
|
608 | |
|
|
609 | The methods "$term->special_encode" and "$term->special_decode" can |
|
|
610 | be used to convert normal strings into this encoding and vice versa. |
|
|
611 | |
|
|
612 | $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]]) |
|
|
613 | Like "$term->ROW_t", but returns an arrayref with rendition bitsets. |
|
|
614 | Rendition bitsets contain information about colour, font, font |
|
|
615 | styles and similar information. See also "$term->ROW_t". |
|
|
616 | |
|
|
617 | When setting rendition, the font mask will be ignored. |
|
|
618 | |
|
|
619 | See the section on RENDITION, above. |
|
|
620 | |
|
|
621 | $length = $term->ROW_l ($row_number[, $new_length]) |
|
|
622 | Returns the number of screen cells that are in use ("the line |
|
|
623 | length"). Unlike the urxvt core, this returns "$term->ncol" if the |
|
|
624 | line is joined with the following one. |
|
|
625 | |
|
|
626 | $bool = $term->is_longer ($row_number) |
|
|
627 | Returns true if the row is part of a multiple-row logical "line" |
|
|
628 | (i.e. joined with the following row), which means all characters are |
|
|
629 | in use and it is continued on the next row (and possibly a |
|
|
630 | continuation of the previous row(s)). |
|
|
631 | |
|
|
632 | $line = $term->line ($row_number) |
|
|
633 | Create and return a new "urxvt::line" object that stores information |
|
|
634 | about the logical line that row $row_number is part of. It supports |
|
|
635 | the following methods: |
|
|
636 | |
|
|
637 | $text = $line->t ([$new_text]) |
|
|
638 | Returns or replaces the full text of the line, similar to |
|
|
639 | "ROW_t" |
|
|
640 | |
|
|
641 | $rend = $line->r ([$new_rend]) |
|
|
642 | Returns or replaces the full rendition array of the line, |
|
|
643 | similar to "ROW_r" |
|
|
644 | |
|
|
645 | $length = $line->l |
|
|
646 | Returns the length of the line in cells, similar to "ROW_l". |
|
|
647 | |
|
|
648 | $rownum = $line->beg |
|
|
649 | $rownum = $line->end |
|
|
650 | Return the row number of the first/last row of the line, |
|
|
651 | respectively. |
|
|
652 | |
|
|
653 | $offset = $line->offset_of ($row, $col) |
|
|
654 | Returns the character offset of the given row|col pair within |
|
|
655 | the logical line. |
|
|
656 | |
|
|
657 | ($row, $col) = $line->coord_of ($offset) |
|
|
658 | Translates a string offset into terminal coordinates again. |
|
|
659 | |
|
|
660 | $text = $term->special_encode $string |
|
|
661 | Converts a perl string into the special encoding used by |
|
|
662 | rxvt-unicode, where one character corresponds to one screen cell. |
|
|
663 | See "$term->ROW_t" for details. |
|
|
664 | |
|
|
665 | $string = $term->special_decode $text |
|
|
666 | Converts rxvt-unicodes text reprsentation into a perl string. See |

685 | |
|
|
686 | $term->ungrab |
|
|
687 | Calls XUngrab for the most recent grab. Is called automatically on |
|
