26 | PREPACKAGED EXTENSIONS |
|
|
27 | This section describes the extensions delivered with this release. 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 | (More) intelligent selection. This extension tries to be more |
|
|
36 | intelligent when the user extends selections (double-click and |
|
|
37 | further clicks). Right now, it tries to select words, urls and |
|
|
38 | complete shell-quoted arguments, which is very convenient, too, if |
|
|
39 | your ls supports "--quoting-style=shell". |
|
|
40 | |
|
|
41 | A double-click usually selects the word under the cursor, further |
|
|
42 | clicks will enlarge the selection. |
|
|
43 | |
|
|
44 | The selection works by trying to match a number of regexes and |
|
|
45 | displaying them in increasing order of length. You can add your own |
|
|
46 | regexes by specifying resources of the form: |
|
|
47 | |
|
|
48 | URxvt.selection.pattern-0: perl-regex |
|
|
49 | URxvt.selection.pattern-1: perl-regex |
|
|
50 | ... |
|
|
51 | |
|
|
52 | The index number (0, 1...) must not have any holes, and each regex |
|
|
53 | must contain at least one pair of capturing parentheses, which will |
|
|
54 | be used for the match. For example, the followign adds a regex that |
|
|
55 | matches everything between two vertical bars: |
|
|
56 | |
|
|
57 | URxvt.selection.pattern-0: \\|([^|]+)\\| |
|
|
58 | |
|
|
59 | You can look at the source of the selection extension to see more |
|
|
60 | interesting uses, such as parsing a line from beginning to end. |
|
|
61 | |
|
|
62 | This extension also offers the following bindable keyboard command: |
|
|
63 | |
|
|
64 | rot13 |
|
|
65 | Rot-13 the selection when activated. Used via keyboard trigger: |
|
|
66 | |
|
|
67 | URxvt.keysym.C-M-r: perl:selection:rot13 |
|
|
68 | |
|
|
69 | option-popup (enabled by default) |
|
|
70 | Binds a popup menu to Ctrl-Button2 that lets you toggle (some) |
|
|
71 | options at runtime. |
|
|
72 | |
|
|
73 | selection-popup (enabled by default) |
|
|
74 | Binds a popup menu to Ctrl-Button3 that lets you convert the |
|
|
75 | selection text into various other formats/action (such as uri |
|
|
76 | unescaping, perl evalution, web-browser starting etc.), depending on |
|
|
77 | content. |
|
|
78 | |
|
|
79 | searchable-scrollback<hotkey> (enabled by default) |
|
|
80 | Adds regex search functionality to the scrollback buffer, triggered |
|
|
81 | by a hotkey (default: "M-s"). While in search mode, normal terminal |
|
|
82 | input/output is suspended and a regex is displayed at the bottom of |
|
|
83 | the screen. |
|
|
84 | |
|
|
85 | Inputting characters appends them to the regex and continues |
|
|
86 | incremental search. "BackSpace" removes a character from the regex, |
|
|
87 | "Up" and "Down" search upwards/downwards in the scrollback buffer, |
|
|
88 | "End" jumps to the bottom. "Escape" leaves search mode and returns |
|
|
89 | to the point where search was started, while "Enter" or "Return" |
|
|
90 | stay at the current position and additionally stores the first match |
|
|
91 | in the current line into the primary selection. |
|
|
92 | |
|
|
93 | selection-autotransform |
|
|
94 | This selection allows you to do automatic transforms on a selection |
|
|
95 | whenever a selection is made. |
|
|
96 | |
|
|
97 | It works by specifying perl snippets (most useful is a single "s///" |
|
|
98 | operator) that modify $_ as resources: |
|
|
99 | |
|
|
100 | URxvt.selection-autotransform.0: transform |
|
|
101 | URxvt.selection-autotransform.1: transform |
|
|
102 | ... |
|
|
103 | |
|
|
104 | For example, the following will transform selections of the form |
|
|
105 | "filename:number", often seen in compiler messages, into "vi |
|
|
106 | +$filename $word": |
|
|
107 | |
|
|
108 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/ |
|
|
109 | |
|
|
110 | And this example matches the same,but replaces it with vi-commands |
|
|
111 | you can paste directly into your (vi :) editor: |
|
|
112 | |
|
|
113 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/ |
|
|
114 | |
|
|
115 | Of course, this can be modified to suit your needs and your editor |
|
|
116 | :) |
|
|
117 | |
|
|
118 | To expand the example above to typical perl error messages ("XXX at |
|
|
119 | FILENAME line YYY."), you need a slightly more elaborate solution: |
|
|
120 | |
|
|
121 | URxvt.selection.pattern-0: ( at .*? line \\d+\\.) |
|
|
122 | URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/ |
|
|
123 | |
|
|
124 | The first line tells the selection code to treat the unchanging part |
|
|
125 | of every error message as a selection pattern, and the second line |
|
|
126 | transforms the message into vi commands to load the file. |
|
|
127 | |
|
|
128 | mark-urls |
|
|
129 | Uses per-line display filtering ("on_line_update") to underline urls |
|
|
130 | and make them clickable. When middle-clicked, the program specified |
|
|
131 | in the resource "urlLauncher" (default "x-www-browser") will be |
|
|
132 | started with the URL as first argument. |
|
|
133 | |
|
|
134 | block-graphics-to-ascii |
|
|
135 | A not very useful example of filtering all text output to the |
|
|
136 | terminal, by replacing all line-drawing characters (U+2500 .. |
|
|
137 | U+259F) by a similar-looking ascii character. |
|
|
138 | |
|
|
139 | digital-clock |
|
|
140 | Displays a digital clock using the built-in overlay. |
|
|
141 | |
|
|
142 | example-refresh-hooks |
|
|
143 | Displays a very simple digital clock in the upper right corner of |
|
|
144 | the window. Illustrates overwriting the refresh callbacks to create |
|
|
145 | your own overlays or changes. |

159 | |
|
|
160 | Argument names also often indicate the type of a parameter. Here are |
|
|
161 | some hints on what they mean: |
|
|
162 | |
|
|
163 | $text |
|
|
164 | Rxvt-unicodes special way of encoding text, where one "unicode" |
|
|
165 | character always represents one screen cell. See ROW_t for a |
|
|
166 | discussion of this format. |
|
|
167 | |
|
|
168 | $string |
|
|
169 | A perl text string, with an emphasis on *text*. It can store all |
|
|
170 | unicode characters and is to be distinguished with text encoded in a |
|
|
171 | specific encoding (often locale-specific) and binary data. |
|
|
172 | |
|
|
173 | $octets |
|
|
174 | Either binary data or - more common - a text string encoded in a |
|
|
175 | locale-specific way. |
|
|
176 | |
|
|
177 | Extension Objects |
|
|
178 | Very perl extension is a perl class. A separate perl object is created |
|
|
179 | for each terminal and each extension and passed as the first parameter |
|
|
180 | to hooks. So extensions can use their $self object without having to |
|
|
181 | think about other extensions, with the exception of methods and members |
|
|
182 | that begin with an underscore character "_": these are reserved for |
|
|
183 | internal use. |
|
|
184 | |
|
|
185 | Although it isn't a "urxvt::term" object, you can call all methods of |
|
|
186 | the "urxvt::term" class on this object. |
|
|
187 | |
|
|
188 | It has the following methods and data members: |
|
|
189 | |
|
|
190 | $urxvt_term = $self->{term} |
|
|
191 | Returns the "urxvt::term" object associated with this instance of |
|
|
192 | the extension. This member *must not* be changed in any way. |
|
|
193 | |
|
|
194 | $self->enable ($hook_name => $cb, [$hook_name => $cb..]) |
|
|
195 | Dynamically enable the given hooks (named without the "on_" prefix) |
|
|
196 | for this extension, replacing any previous hook. This is useful when |
|
|
197 | you want to overwrite time-critical hooks only temporarily. |
|
|
198 | |
|
|
199 | $self->disable ($hook_name[, $hook_name..]) |
|
|
200 | Dynamically disable the given hooks. |

78 | on_focus_in $term |
249 | on_sel_extend $term |
79 | Called whenever the window gets the keyboard focus, before urxvt |
250 | Called whenever the user tries to extend the selection (e.g. with a |
80 | does focus in processing. |
251 | double click) and is either supposed to return false (normal |
|
|
252 | operation), or should extend the selection itelf and return true to |
|
|
253 | suppress the built-in processing. This can happen multiple times, as |
|
|
254 | long as the callback returns true, it will be called on every |
|
|
255 | further click by the user and is supposed to enlarge the selection |
|
|
256 | more and more, if possible. |
81 | |
257 | |
82 | on_focus_out $term |
258 | See the selection example extension. |
83 | Called wheneever the window loses keyboard focus, before urxvt does |
|
|
84 | focus out processing. |
|
|
85 | |
259 | |
86 | on_view_change $term, $offset |

272 | the total number of lines that will be in the scrollback buffer. |
99 | |
273 | |
100 | on_tty_activity $term *NYI* |
274 | on_osc_seq $term, $string |
101 | Called whenever the program(s) running in the urxvt window send |
275 | Called whenever the ESC ] 777 ; string ST command sequence (OSC = |
102 | output. |
276 | operating system command) is processed. Cursor position and other |
|
|
277 | state information is up-to-date when this happens. For |
|
|
278 | interoperability, the string should start with the extension name |
|
|
279 | and a colon, to distinguish it from commands for other extensions, |
|
|
280 | and this might be enforced in the future. |
|
|
281 | |
|
|
282 | Be careful not ever to trust (in a security sense) the data you |
|
|
283 | receive, as its source can not easily be controleld (e-mail content, |
|
|
284 | messages from other users on the same system etc.). |
|
|
285 | |
|
|
286 | on_add_lines $term, $string |
|
|
287 | Called whenever text is about to be output, with the text as |
|
|
288 | argument. You can filter/change and output the text yourself by |
|
|
289 | returning a true value and calling "$term->scr_add_lines" yourself. |
|
|
290 | Please note that this might be very slow, however, as your hook is |
|
|
291 | called for all text being output. |
|
|
292 | |
|
|
293 | on_tt_write $term, $octets |
|
|
294 | Called whenever some data is written to the tty/pty and can be used |
|
|
295 | to suppress or filter tty input. |
|
|
296 | |
|
|
297 | on_line_update $term, $row |
|
|
298 | Called whenever a line was updated or changed. Can be used to filter |
|
|
299 | screen output (e.g. underline urls or other useless stuff). Only |
|
|
300 | lines that are being shown will be filtered, and, due to performance |
|
|
301 | reasons, not always immediately. |
|
|
302 | |
|
|
303 | The row number is always the topmost row of the line if the line |
|
|
304 | spans multiple rows. |
|
|
305 | |
|
|
306 | Please note that, if you change the line, then the hook might get |
|
|
307 | called later with the already-modified line (e.g. if unrelated parts |
|
|
308 | change), so you cannot just toggle rendition bits, but only set |
|
|
309 | them. |
103 | |

|
320 | on_keyboard_command $term, $string |
|
|
321 | Called whenever the user presses a key combination that has a |
|
|
322 | "perl:string" action bound to it (see description of the keysym |
|
|
323 | resource in the rxvt(1) manpage). |
|
|
324 | |
|
|
325 | on_x_event $term, $event |
|
|
326 | Called on every X event received on the vt window (and possibly |
|
|
327 | other windows). Should only be used as a last resort. Most event |
|
|
328 | structure members are not passed. |
|
|
329 | |
|
|
330 | on_focus_in $term |

418 | |
|
|
419 | RENDITION |
|
|
420 | Rendition bitsets contain information about colour, font, font styles |
|
|
421 | and similar information for each screen cell. |
|
|
422 | |
|
|
423 | The following "macros" deal with changes in rendition sets. You should |
|
|
424 | never just create a bitset, you should always modify an existing one, as |
|
|
425 | they contain important information required for correct operation of |
|
|
426 | rxvt-unicode. |
|
|
427 | |
|
|
428 | $rend = urxvt::DEFAULT_RSTYLE |
|
|
429 | Returns the default rendition, as used when the terminal is starting |
|
|
430 | up or being reset. Useful as a base to start when creating |
|
|
431 | renditions. |
|
|
432 | |
|
|
433 | $rend = urxvt::OVERLAY_RSTYLE |
|
|
434 | Return the rendition mask used for overlays by default. |
|
|
435 | |
|
|
436 | $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline |
|
|
437 | Return the bit that enabled bold, italic, blink, reverse-video and |
|
|
438 | underline, respectively. To enable such a style, just logically OR |
|
|
439 | it into the bitset. |
|
|
440 | |
|
|
441 | $foreground = urxvt::GET_BASEFG $rend |
|
|
442 | $background = urxvt::GET_BASEBG $rend |
|
|
443 | Return the foreground/background colour index, respectively. |
|
|
444 | |
|
|
445 | $rend = urxvt::SET_FGCOLOR $rend, $new_colour |
|
|
446 | $rend = urxvt::SET_BGCOLOR $rend, $new_colour |
|
|
447 | Replace the foreground/background colour in the rendition mask with |
|
|
448 | the specified one. |
|
|
449 | |
|
|
450 | $value = urxvt::GET_CUSTOM $rend |
|
|
451 | Return the "custom" value: Every rendition has 5 bits for use by |
|
|
452 | extensions. They can be set and changed as you like and are |
|
|
453 | initially zero. |
|
|
454 | |
|
|
455 | $rend = urxvt::SET_CUSTOM $rend, $new_value |
|
|
456 | Change the custom value. |
|
|
457 | |
|
|
458 | The "urxvt::anyevent" Class |
|
|
459 | The sole purpose of this class is to deliver an interface to the |
|
|
460 | "AnyEvent" module - any module using it will work inside urxvt without |
|
|
461 | further programming. The only exception is that you cannot wait on |
|
|
462 | condition variables, but non-blocking condvar use is ok. What this means |
|
|
463 | is that you cannot use blocking APIs, but the non-blocking variant |
|
|
464 | should work. |
|
|
465 | |
130 | The "urxvt::term" Class |
466 | The "urxvt::term" Class |
|
|
467 | $term = new urxvt::term $envhashref, $rxvtname, [arg...] |
|
|
468 | Creates a new terminal, very similar as if you had started it with |
|
|
469 | system "$rxvtname, arg...". $envhashref must be a reference to a |
|
|
470 | %ENV-like hash which defines the environment of the new terminal. |
|
|
471 | |
|
|
472 | Croaks (and probably outputs an error message) if the new instance |
|
|
473 | couldn't be created. Returns "undef" if the new instance didn't |
|
|
474 | initialise perl, and the terminal object otherwise. The "init" and |
|
|
475 | "start" hooks will be called during this call. |
|
|
476 | |
|
|
477 | $term->destroy |
|
|
478 | Destroy the terminal object (close the window, free resources etc.). |
|
|
479 | Please note that rxvt will not exit as long as any event watchers |
|
|
480 | (timers, io watchers) are still active. |
|
|
481 | |
|
|
482 | $isset = $term->option ($optval[, $set]) |
|
|
483 | Returns true if the option specified by $optval is enabled, and |
|
|
484 | optionally change it. All option values are stored by name in the |
|
|
485 | hash %urxvt::OPTION. Options not enabled in this binary are not in |
|
|
486 | the hash. |

534 | or class name, i.e. "$term->x_resource ("boldFont")" should return |
|
|
535 | the same value as used by this instance of rxvt-unicode. Returns |

538 | This method should only be called during the "on_start" hook, as |

|
|
549 | |
|
|
550 | ($row, $col) = $term->screen_cur ([$row, $col]) |
|
|
551 | Return the current coordinates of the text cursor position and |

561 | $term->selection_make ($eventtime[, $rectangular]) |
|
|
562 | Tries to make a selection as set by "selection_beg" and |
|
|
563 | "selection_end". If $rectangular is true (default: false), a |
|
|

191 | |
594 | |
192 | $term->scr_overlay_set_char ($x, $y, $char, $rend = OVERLAY_RSTYLE) |
595 | The methods currently supported on "urxvt::overlay" objects are: |
193 | Put a single character (specified numerically) at the given overlay |
|
|
194 | position. |
|
|
195 | |
596 | |
196 | $term->scr_overlay_set ($x, $y, $text) |
597 | $overlay->set ($x, $y, $text, $rend) |
197 | Write a string at the given position into the overlay. |
598 | Similar to "$term->ROW_t" and "$term->ROW_r" in that it puts |
|
|
599 | text in rxvt-unicode's special encoding and an array of |
|
|
600 | rendition values at a specific position inside the overlay. |
198 | |
601 | |

|
608 | $popup = $term->popup ($event) |
|
|
609 | Creates a new "urxvt::popup" object that implements a popup menu. |
|
|
610 | The $event *must* be the event causing the menu to pop up (a button |
|
|
611 | event, currently). |
|
|
612 | |

|
623 | |
|
|
624 | $term->scr_xor_span ($beg_row, $beg_col, $end_row, $end_col[, $rstyle]) |
|
|
625 | XORs the rendition values in the given span with the provided value |
|
|
626 | (default: "RS_RVid"), which *MUST NOT* contain font styles. Useful |
|
|
627 | in refresh hooks to provide effects similar to the selection. |
|
|
628 | |
|
|
629 | $term->scr_xor_rect ($beg_row, $beg_col, $end_row, $end_col[, $rstyle1[, |
|
|
630 | $rstyle2]]) |
|
|
631 | Similar to "scr_xor_span", but xors a rectangle instead. Trailing |
|
|
632 | whitespace will additionally be xored with the $rstyle2, which |
|
|
633 | defaults to "RS_RVid | RS_Uline", which removes reverse video again |
|
|
634 | and underlines it instead. Both styles *MUST NOT* contain font |
|
|
635 | styles. |

640 | $term->scr_add_lines ($string) |
|
|
641 | Write the given text string to the screen, as if output by the |
|
|
642 | application running inside the terminal. It may not contain command |
|
|
643 | sequences (escape codes), but is free to use line feeds, carriage |
|
|
644 | returns and tabs. The string is a normal text string, not in |
|
|
645 | locale-dependent encoding. |
|
|
646 | |
|
|
647 | Normally its not a good idea to use this function, as programs might |
|
|
648 | be confused by changes in cursor position or scrolling. Its useful |
|
|
649 | inside a "on_add_lines" hook, though. |
|
|
650 | |
|
|
651 | $term->cmd_parse ($octets) |
|
|
652 | Similar to "scr_add_lines", but the argument must be in the |
|
|
653 | locale-specific encoding of the terminal and can contain command |
|
|
654 | sequences (escape codes) that will be interpreted. |
209 | |

660 | "$term->locale_encode". |
|
|
661 | |
|
|
662 | $old_events = $term->pty_ev_events ([$new_events]) |
|
|
663 | Replaces the event mask of the pty watcher by the given event mask. |
|
|
664 | Can be used to suppress input and output handling to the pty/tty. |
|
|
665 | See the description of "urxvt::timer->events". Make sure to always |
|
|
666 | restore the previous value. |
|
|
667 | |
|
|
668 | $windowid = $term->parent |
|
|
669 | Return the window id of the toplevel window. |
|
|
670 | |
|
|
671 | $windowid = $term->vt |
|
|
672 | Return the window id of the terminal window. |
|
|
673 | |
|
|
674 | $term->vt_emask_add ($x_event_mask) |
|
|
675 | Adds the specified events to the vt event mask. Useful e.g. when you |
|
|
676 | want to receive pointer events all the times: |
|
|
677 | |
|
|
678 | $term->vt_emask_add (urxvt::PointerMotionMask); |
|
|
679 | |
|
|
680 | $window_width = $term->width |
|
|
681 | $window_height = $term->height |
|
|
682 | $font_width = $term->fwidth |
|
|
683 | $font_height = $term->fheight |
|
|
684 | $font_ascent = $term->fbase |
|
|
685 | $terminal_rows = $term->nrow |
|
|
686 | $terminal_columns = $term->ncol |
|
|
687 | $has_focus = $term->focus |
|
|
688 | $is_mapped = $term->mapped |
|
|
689 | $max_scrollback = $term->saveLines |
|
|
690 | $nrow_plus_saveLines = $term->total_rows |
|
|
691 | $topmost_scrollback_row = $term->top_row |
|
|
692 | Return various integers describing terminal characteristics. |
|
|
693 | |
|
|
694 | $x_display = $term->display_id |
|
|
695 | Return the DISPLAY used by rxvt-unicode. |
|
|
696 | |
|
|
697 | $lc_ctype = $term->locale |
|
|
698 | Returns the LC_CTYPE category string used by this rxvt-unicode. |
|
|
699 | |
|
|
700 | $env = $term->env |
|
|
701 | Returns a copy of the environment in effect for the terminal as a |
|
|
702 | hashref similar to "\%ENV". |
|
|
703 | |
|
|
704 | $modifiermask = $term->ModLevel3Mask |
|
|
705 | $modifiermask = $term->ModMetaMask |
|
|
706 | $modifiermask = $term->ModNumLockMask |
|
|
707 | Return the modifier masks corresponding to the "ISO Level 3 Shift" |
|
|
708 | (often AltGr), the meta key (often Alt) and the num lock key, if |
|
|
709 | applicable. |
|
|
710 | |
|
|
711 | $view_start = $term->view_start ([$newvalue]) |
|
|
712 | Returns the row number of the topmost displayed line. Maximum value |
|
|
713 | is 0, which displays the normal terminal contents. Lower values |
|
|
714 | scroll this many lines into the scrollback buffer. |
|
|
715 | |
|
|
716 | $term->want_refresh |
|
|
717 | Requests a screen refresh. At the next opportunity, rxvt-unicode |
|
|
718 | will compare the on-screen display with its stored representation. |
|
|
719 | If they differ, it redraws the differences. |
|
|
720 | |
|
|
721 | Used after changing terminal contents to display them. |
|
|
722 | |
|
|
723 | $text = $term->ROW_t ($row_number[, $new_text[, $start_col]]) |
|
|
724 | Returns the text of the entire row with number $row_number. Row 0 is |
|
|
725 | the topmost terminal line, row "$term->$ncol-1" is the bottommost |
|
|
726 | terminal line. The scrollback buffer starts at line -1 and extends |
|
|
727 | to line "-$term->nsaved". Nothing will be returned if a nonexistent |
|
|
728 | line is requested. |
|
|
729 | |
|
|
730 | If $new_text is specified, it will replace characters in the current |
|
|
731 | line, starting at column $start_col (default 0), which is useful to |
|
|
732 | replace only parts of a line. The font index in the rendition will |
|
|
733 | automatically be updated. |
|
|
734 | |
|
|
735 | $text is in a special encoding: tabs and wide characters that use |
|
|
736 | more than one cell when displayed are padded with urxvt::NOCHAR |
|
|
737 | characters ("chr 65535"). Characters with combining characters and |
|
|
738 | other characters that do not fit into the normal tetx encoding will |
|
|
739 | be replaced with characters in the private use area. |
|
|
740 | |
|
|
741 | You have to obey this encoding when changing text. The advantage is |
|
|
742 | that "substr" and similar functions work on screen cells and not on |
|
|
743 | characters. |
|
|
744 | |
|
|
745 | The methods "$term->special_encode" and "$term->special_decode" can |
|
|
746 | be used to convert normal strings into this encoding and vice versa. |
|
|
747 | |
|
|
748 | $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]]) |
|
|
749 | Like "$term->ROW_t", but returns an arrayref with rendition bitsets. |
|
|
750 | Rendition bitsets contain information about colour, font, font |
|
|
751 | styles and similar information. See also "$term->ROW_t". |
|
|
752 | |
|
|
753 | When setting rendition, the font mask will be ignored. |
|
|
754 | |
|
|
755 | See the section on RENDITION, above. |
|
|
756 | |
|
|
757 | $length = $term->ROW_l ($row_number[, $new_length]) |
|
|
758 | Returns the number of screen cells that are in use ("the line |
|
|
759 | length"). Unlike the urxvt core, this returns "$term->ncol" if the |
|
|
760 | line is joined with the following one. |
|
|
761 | |
|
|
762 | $bool = $term->is_longer ($row_number) |
|
|
763 | Returns true if the row is part of a multiple-row logical "line" |
|
|
764 | (i.e. joined with the following row), which means all characters are |
|
|
765 | in use and it is continued on the next row (and possibly a |
|
|
766 | continuation of the previous row(s)). |
|
|
767 | |
|
|
768 | $line = $term->line ($row_number) |
|
|
769 | Create and return a new "urxvt::line" object that stores information |
|
|
770 | about the logical line that row $row_number is part of. It supports |
|
|
771 | the following methods: |
|
|
772 | |
|
|
773 | $text = $line->t ([$new_text]) |
|
|
774 | Returns or replaces the full text of the line, similar to |
|
|
775 | "ROW_t" |
|
|
776 | |
|
|
777 | $rend = $line->r ([$new_rend]) |
|
|
778 | Returns or replaces the full rendition array of the line, |
|
|
779 | similar to "ROW_r" |
|
|
780 | |
|
|
781 | $length = $line->l |
|
|
782 | Returns the length of the line in cells, similar to "ROW_l". |
|
|
783 | |
|
|
784 | $rownum = $line->beg |
|
|
785 | $rownum = $line->end |
|
|
786 | Return the row number of the first/last row of the line, |
|
|
787 | respectively. |
|
|
788 | |
|
|
789 | $offset = $line->offset_of ($row, $col) |
|
|
790 | Returns the character offset of the given row|col pair within |
|
|
791 | the logical line. Works for rows outside the line, too, and |
|
|
792 | returns corresponding offsets outside the string. |
|
|
793 | |
|
|
794 | ($row, $col) = $line->coord_of ($offset) |
|
|
795 | Translates a string offset into terminal coordinates again. |
|
|
796 | |
|
|
797 | $text = $term->special_encode $string |
|
|
798 | Converts a perl string into the special encoding used by |
|
|
799 | rxvt-unicode, where one character corresponds to one screen cell. |
|
|
800 | See "$term->ROW_t" for details. |
|
|
801 | |
|
|
802 | $string = $term->special_decode $text |
|
|
803 | Converts rxvt-unicodes text reprsentation into a perl string. See |
|
|
804 | "$term->ROW_t" for details. |
|
|
805 | |
|
|
806 | $success = $term->grab_button ($button, $modifiermask) |
|
|
807 | Registers a synchronous button grab. See the XGrabButton manpage. |
|
|
808 | |
|
|
809 | $success = $term->grab ($eventtime[, $sync]) |
|
|
810 | Calls XGrabPointer and XGrabKeyboard in asynchronous (default) or |
|
|
811 | synchronous ($sync is true). Also remembers the grab timestampe. |
|
|
812 | |
|
|
813 | $term->allow_events_async |
|
|
814 | Calls XAllowEvents with AsyncBoth for the most recent grab. |
|
|
815 | |
|
|
816 | $term->allow_events_sync |

819 | $term->allow_events_replay |
|
|
820 | Calls XAllowEvents with both ReplayPointer and ReplayKeyboard for |
|
|
821 | the most recent grab. |
|
|
822 | |
|
|
823 | $term->ungrab |
|
|
824 | Calls XUngrab for the most recent grab. Is called automatically on |
|
|
825 | evaluation errors, as it is better to lose the grab in the error |
|
|
826 | case as the session. |
|
|
827 | |
|
|
828 | The "urxvt::popup" Class |
|
|
829 | $popup->add_title ($title) |
