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 | Or by adding them to the resource for extensions loaded by default: |
|
|
35 | |
|
|
36 | URxvt.perl-ext-common: default,automove-background,selection-autotransform |
|
|
37 | |
|
|
38 | selection (enabled by default) |
|
|
39 | (More) intelligent selection. This extension tries to be more |
|
|
40 | intelligent when the user extends selections (double-click and |
|
|
41 | further clicks). Right now, it tries to select words, urls and |
|
|
42 | complete shell-quoted arguments, which is very convenient, too, if |
|
|
43 | your ls supports "--quoting-style=shell". |
|
|
44 | |
|
|
45 | A double-click usually selects the word under the cursor, further |
|
|
46 | clicks will enlarge the selection. |
|
|
47 | |
|
|
48 | The selection works by trying to match a number of regexes and |
|
|
49 | displaying them in increasing order of length. You can add your own |
|
|
50 | regexes by specifying resources of the form: |
|
|
51 | |
|
|
52 | URxvt.selection.pattern-0: perl-regex |
|
|
53 | URxvt.selection.pattern-1: perl-regex |
|
|
54 | ... |
|
|
55 | |
|
|
56 | The index number (0, 1...) must not have any holes, and each regex |
|
|
57 | must contain at least one pair of capturing parentheses, which will |
|
|
58 | be used for the match. For example, the followign adds a regex that |
|
|
59 | matches everything between two vertical bars: |
|
|
60 | |
|
|
61 | URxvt.selection.pattern-0: \\|([^|]+)\\| |
|
|
62 | |
|
|
63 | Another example: Programs I use often output "absolute path: " at |
|
|
64 | the beginning of a line when they process multiple files. The |
|
|
65 | following pattern matches the filename (note, there is a single |
|
|
66 | space at the very end): |
|
|
67 | |
|
|
68 | URxvt.selection.pattern-0: ^(/[^:]+):\ |
|
|
69 | |
|
|
70 | You can look at the source of the selection extension to see more |
|
|
71 | interesting uses, such as parsing a line from beginning to end. |
|
|
72 | |
|
|
73 | This extension also offers following bindable keyboard commands: |
|
|
74 | |
|
|
75 | rot13 |
|
|
76 | Rot-13 the selection when activated. Used via keyboard trigger: |
|
|
77 | |
|
|
78 | URxvt.keysym.C-M-r: perl:selection:rot13 |
|
|
79 | |
|
|
80 | option-popup (enabled by default) |
|
|
81 | Binds a popup menu to Ctrl-Button2 that lets you toggle (some) |
|
|
82 | options at runtime. |
|
|
83 | |
|
|
84 | selection-popup (enabled by default) |
|
|
85 | Binds a popup menu to Ctrl-Button3 that lets you convert the |
|
|
86 | selection text into various other formats/action (such as uri |
|
|
87 | unescaping, perl evaluation, web-browser starting etc.), depending |
|
|
88 | on content. |
|
|
89 | |
|
|
90 | Other extensions can extend this popup menu by pushing a code |
|
|
91 | reference onto "@{ $term-"{selection_popup_hook} }>, that is called |
|
|
92 | whenever the popup is displayed. |
|
|
93 | |
|
|
94 | It's sole argument is the popup menu, which can be modified. The |
|
|
95 | selection is in $_, which can be used to decide wether to add |
|
|
96 | something or not. It should either return nothing or a string and a |
|
|
97 | code reference. The string will be used as button text and the code |
|
|
98 | reference will be called when the button gets activated and should |
|
|
99 | transform $_. |
|
|
100 | |
|
|
101 | The following will add an entry "a to b" that transforms all "a"s in |
|
|
102 | the selection to "b"s, but only if the selection currently contains |
|
|
103 | any "a"s: |
|
|
104 | |
|
|
105 | push @{ $self->{term}{selection_popup_hook} }, sub { |
|
|
106 | /a/ ? ("a to be" => sub { s/a/b/g } |
|
|
107 | : () |
|
|
108 | }; |
|
|
109 | |
|
|
110 | searchable-scrollback<hotkey> (enabled by default) |
|
|
111 | Adds regex search functionality to the scrollback buffer, triggered |
|
|
112 | by a hotkey (default: "M-s"). While in search mode, normal terminal |
|
|
113 | input/output is suspended and a regex is displayed at the bottom of |
|
|
114 | the screen. |
|
|
115 | |
|
|
116 | Inputting characters appends them to the regex and continues |
|
|
117 | incremental search. "BackSpace" removes a character from the regex, |
|
|
118 | "Up" and "Down" search upwards/downwards in the scrollback buffer, |
|
|
119 | "End" jumps to the bottom. "Escape" leaves search mode and returns |
|
|
120 | to the point where search was started, while "Enter" or "Return" |
|
|
121 | stay at the current position and additionally stores the first match |
|
|
122 | in the current line into the primary selection. |
|
|
123 | |
|
|
124 | readline (enabled by default) |
|
|
125 | A support package that tries to make editing with readline easier. |
|
|
126 | At the moment, it reacts to clicking with the left mouse button by |
|
|
127 | trying to move the text cursor to this position. It does so by |
|
|
128 | generating as many cursor-left or cursor-right keypresses as |
|
|
129 | required (the this only works for programs that correctly support |
|
|
130 | wide characters). |
|
|
131 | |
|
|
132 | To avoid too many false positives, this is only done when: |
|
|
133 | |
|
|
134 | - the tty is in ICANON state. |
|
|
135 | - the text cursor is visible. |
|
|
136 | - the primary screen is currently being displayed. |
|
|
137 | - the mouse is on the same (multi-row-) line as the text cursor. |
|
|
138 | |
|
|
139 | The normal selection mechanism isn't disabled, so quick successive |
|
|
140 | clicks might interfere with selection creation in harmless ways. |
|
|
141 | |
|
|
142 | selection-autotransform |
|
|
143 | This selection allows you to do automatic transforms on a selection |
|
|
144 | whenever a selection is made. |
|
|
145 | |
|
|
146 | It works by specifying perl snippets (most useful is a single "s///" |
|
|
147 | operator) that modify $_ as resources: |
|
|
148 | |
|
|
149 | URxvt.selection-autotransform.0: transform |
|
|
150 | URxvt.selection-autotransform.1: transform |
|
|
151 | ... |
|
|
152 | |
|
|
153 | For example, the following will transform selections of the form |
|
|
154 | "filename:number", often seen in compiler messages, into "vi |
|
|
155 | +$filename $word": |
|
|
156 | |
|
|
157 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/ |
|
|
158 | |
|
|
159 | And this example matches the same,but replaces it with vi-commands |
|
|
160 | you can paste directly into your (vi :) editor: |
|
|
161 | |
|
|
162 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/ |
|
|
163 | |
|
|
164 | Of course, this can be modified to suit your needs and your editor |
|
|
165 | :) |
|
|
166 | |
|
|
167 | To expand the example above to typical perl error messages ("XXX at |
|
|
168 | FILENAME line YYY."), you need a slightly more elaborate solution: |
|
|
169 | |
|
|
170 | URxvt.selection.pattern-0: ( at .*? line \\d+[,.]) |
|
|
171 | URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/ |
|
|
172 | |
|
|
173 | The first line tells the selection code to treat the unchanging part |
|
|
174 | of every error message as a selection pattern, and the second line |
|
|
175 | transforms the message into vi commands to load the file. |
|
|
176 | |
|
|
177 | tabbed |
|
|
178 | This transforms the terminal into a tabbar with additional |
|
|
179 | terminals, that is, it implements what is commonly refered to as |
|
|
180 | "tabbed terminal". The topmost line displays a "[NEW]" button, |
|
|
181 | which, when clicked, will add a new tab, followed by one button per |
|
|
182 | tab. |
|
|
183 | |
|
|
184 | Clicking a button will activate that tab. Pressing Shift-Left and |
|
|
185 | Shift-Right will switch to the tab left or right of the current one, |
|
|
186 | while Shift-Down creates a new tab. |
|
|
187 | |
|
|
188 | The tabbar itself can be configured similarly to a normal terminal, |
|
|
189 | but with a resource class of "URxvt.tabbed". In addition, it |
|
|
190 | supports the following four resources (shown with defaults): |
|
|
191 | |
|
|
192 | URxvt.tabbed.tabbar-fg: <colour-index, default 3> |
|
|
193 | URxvt.tabbed.tabbar-bg: <colour-index, default 0> |
|
|
194 | URxvt.tabbed.tab-fg: <colour-index, default 0> |
|
|
195 | URxvt.tabbed.tab-bg: <colour-index, default 1> |
|
|
196 | |
|
|
197 | See *COLOR AND GRAPHICS* in the rxvt(1) manpage for valid indices. |
|
|
198 | |
|
|
199 | mark-urls |
|
|
200 | Uses per-line display filtering ("on_line_update") to underline urls |
|
|
201 | and make them clickable. When middle-clicked, the program specified |
|
|
202 | in the resource "urlLauncher" (default "x-www-browser") will be |
|
|
203 | started with the URL as first argument. |
|
|
204 | |
|
|
205 | xim-onthespot |
|
|
206 | This (experimental) perl extension implements OnTheSpot editing. It |
|
|
207 | does not work perfectly, and some input methods don't seem to work |
|
|
208 | well with OnTheSpot editing in general, but it seems to work at |
|
|
209 | leats for SCIM and kinput2. |
|
|
210 | |
|
|
211 | You enable it by specifying this extension and a preedit style of |
|
|
212 | "OnTheSpot", i.e.: |
|
|
213 | |
|
|
214 | rxvt -pt OnTheSpot -pe xim-onthespot |
|
|
215 | |
|
|
216 | automove-background |
|
|
217 | This is basically a one-line extension that dynamically changes the |
|
|
218 | background pixmap offset to the window position, in effect creating |
|
|
219 | the same effect as pseudo transparency with a custom pixmap. No |
|
|
220 | scaling is supported in this mode. Exmaple: |
|
|
221 | |
|
|
222 | rxvt -pixmap background.xpm -pe automove-background |
|
|
223 | |
|
|
224 | block-graphics-to-ascii |
|
|
225 | A not very useful example of filtering all text output to the |
|
|
226 | terminal, by replacing all line-drawing characters (U+2500 .. |
|
|
227 | U+259F) by a similar-looking ascii character. |
|
|
228 | |
|
|
229 | digital-clock |
|
|
230 | Displays a digital clock using the built-in overlay. |
|
|
231 | |
|
|
232 | remote-clipboard |
|
|
233 | Somewhat of a misnomer, this extension adds two menu entries to the |
|
|
234 | selection popup that allows one ti run external commands to store |
|
|
235 | the selection somewhere and fetch it again. |
|
|
236 | |
|
|
237 | We use it to implement a "distributed selection mechanism", which |
|
|
238 | just means that one command uploads the file to a remote server, and |
|
|
239 | another reads it. |
|
|
240 | |
|
|
241 | The commands can be set using the "URxvt.remote-selection.store" and |
|
|
242 | "URxvt.remote-selection.fetch" resources. The first should read the |
|
|
243 | selection to store from STDIN (always in UTF-8), the second should |
|
|
244 | provide the selection data on STDOUT (also in UTF-8). |
|
|
245 | |
|
|
246 | The defaults (which are likely useless to you) use rsh and cat: |
|
|
247 | |
|
|
248 | URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection' |
|
|
249 | URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection' |
|
|
250 | |
|
|
251 | selection-pastebin |
|
|
252 | This is a little rarely useful extension that Uploads the selection |
|
|
253 | as textfile to a remote site (or does other things). (The |
|
|
254 | implementation is not currently secure for use in a multiuser |
|
|
255 | environment as it writes to /tmp directly.). |
|
|
256 | |
|
|
257 | It listens to the "selection-pastebin:remote-pastebin" keyboard |
|
|
258 | command, i.e. |
|
|
259 | |
|
|
260 | URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
|
|
261 | |
|
|
262 | Pressing this combination runs a command with "%" replaced by the |
|
|
263 | name of the textfile. This command can be set via a resource: |
|
|
264 | |
|
|
265 | URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/. |
|
|
266 | |
|
|
267 | And the default is likely not useful to anybody but the few people |
|
|
268 | around here :) |
|
|
269 | |
|
|
270 | The name of the textfile is the hex encoded md5 sum of the |
|
|
271 | selection, so the same content should lead to the same filename. |
|
|
272 | |
|
|
273 | After a successful upload the selection will be replaced by the text |
|
|
274 | given in the "selection-pastebin-url" resource (again, the % is the |
|
|
275 | placeholder for the filename): |
|
|
276 | |
|
|
277 | URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/% |
|
|
278 | |
|
|
279 | example-refresh-hooks |
|
|
280 | Displays a very simple digital clock in the upper right corner of |
|
|
281 | the window. Illustrates overwriting the refresh callbacks to create |
|
|
282 | your own overlays or changes. |
|

|
|
297 | Argument names also often indicate the type of a parameter. Here are |
|
|
298 | some hints on what they mean: |
|
|
299 | |
|
|
300 | $text |
|
|
301 | Rxvt-unicodes special way of encoding text, where one "unicode" |
|
|
302 | character always represents one screen cell. See ROW_t for a |
|
|
303 | discussion of this format. |
|
|
304 | |
|
|
305 | $string |
|
|
306 | A perl text string, with an emphasis on *text*. It can store all |
|
|
307 | unicode characters and is to be distinguished with text encoded in a |
|
|
308 | specific encoding (often locale-specific) and binary data. |
|
|
309 | |
|
|
310 | $octets |
|
|
311 | Either binary data or - more common - a text string encoded in a |
|
|
312 | locale-specific way. |
|
|
313 | |
|
|
314 | Extension Objects |
|
|
315 | Very perl extension is a perl class. A separate perl object is created |
|
|
316 | for each terminal and each extension and passed as the first parameter |
|
|
317 | to hooks. So extensions can use their $self object without having to |
|
|
318 | think about other extensions, with the exception of methods and members |
|
|
319 | that begin with an underscore character "_": these are reserved for |
|
|
320 | internal use. |
|
|
321 | |
|
|
322 | Although it isn't a "urxvt::term" object, you can call all methods of |
|
|
323 | the "urxvt::term" class on this object. |
|
|
324 | |
|
|
325 | It has the following methods and data members: |
|
|
326 | |
|
|
327 | $urxvt_term = $self->{term} |
|
|
328 | Returns the "urxvt::term" object associated with this instance of |
|
|
329 | the extension. This member *must not* be changed in any way. |
|
|
330 | |
|
|
331 | $self->enable ($hook_name => $cb, [$hook_name => $cb..]) |
|
|
332 | Dynamically enable the given hooks (named without the "on_" prefix) |
|
|
333 | for this extension, replacing any previous hook. This is useful when |
|
|
334 | you want to overwrite time-critical hooks only temporarily. |
|
|
335 | |
|
|
336 | $self->disable ($hook_name[, $hook_name..]) |
|
|
337 | Dynamically disable the given hooks. |

355 | to call or deliver senseless data, as terminal size and other |
|
|
356 | characteristics have not yet been determined. You can safely query |
|
|
357 | and change resources and options, though. For many purposes the |
|
|
358 | "on_start" hook is a better place. |
|
|
359 | |
|
|
360 | on_start $term |
|
|
361 | Called at the very end of initialisation of a new terminal, just |
|
|
362 | before trying to map (display) the toplevel and returning to the |
|

374 | on_child_start $term, $pid |
59 | Called at the very end of initialisation of a new terminal, just |
375 | Called just after the child process has been "fork"ed. |
60 | before returning to the mainloop. |
376 | |
|
|
377 | on_child_exit $term, $status |
|
|
378 | Called just after the child process has exited. $status is the |

79 | on_focus_in $term |
398 | on_sel_extend $term |
80 | Called whenever the window gets the keyboard focus, before urxvt |
399 | Called whenever the user tries to extend the selection (e.g. with a |
81 | does focus in processing. |
400 | double click) and is either supposed to return false (normal |
|
|
401 | operation), or should extend the selection itelf and return true to |
|
|
402 | suppress the built-in processing. This can happen multiple times, as |
|
|
403 | long as the callback returns true, it will be called on every |
|
|
404 | further click by the user and is supposed to enlarge the selection |
|
|
405 | more and more, if possible. |
82 | |
406 | |
83 | on_focus_out $term |
407 | See the selection example extension. |

100 | |
422 | |
101 | on_tty_activity $term *NYI* |
423 | on_osc_seq $term, $string |
102 | Called whenever the program(s) running in the urxvt window send |
424 | Called whenever the ESC ] 777 ; string ST command sequence (OSC = |
103 | output. |
425 | operating system command) is processed. Cursor position and other |
|
|
426 | state information is up-to-date when this happens. For |
|
|
427 | interoperability, the string should start with the extension name |
|
|
428 | and a colon, to distinguish it from commands for other extensions, |
|
|
429 | and this might be enforced in the future. |
|
|
430 | |
|
|
431 | Be careful not ever to trust (in a security sense) the data you |
|
|
432 | receive, as its source can not easily be controleld (e-mail content, |
|
|
433 | messages from other users on the same system etc.). |
|
|
434 | |
|
|
435 | on_add_lines $term, $string |
|
|
436 | Called whenever text is about to be output, with the text as |
|
|
437 | argument. You can filter/change and output the text yourself by |
|
|
438 | returning a true value and calling "$term->scr_add_lines" yourself. |
|
|
439 | Please note that this might be very slow, however, as your hook is |
|
|
440 | called for all text being output. |
|
|
441 | |
|
|
442 | on_tt_write $term, $octets |
|
|
443 | Called whenever some data is written to the tty/pty and can be used |
|
|
444 | to suppress or filter tty input. |
|
|
445 | |
|
|
446 | on_line_update $term, $row |
|
|
447 | Called whenever a line was updated or changed. Can be used to filter |
|
|
448 | screen output (e.g. underline urls or other useless stuff). Only |
|
|
449 | lines that are being shown will be filtered, and, due to performance |
|
|
450 | reasons, not always immediately. |
|
|
451 | |
|
|
452 | The row number is always the topmost row of the line if the line |
|
|
453 | spans multiple rows. |
|
|
454 | |
|
|
455 | Please note that, if you change the line, then the hook might get |
|
|
456 | called later with the already-modified line (e.g. if unrelated parts |
|
|
457 | change), so you cannot just toggle rendition bits, but only set |
|
|
458 | them. |
104 | |

472 | keysym resource in the rxvt(1) manpage). |
|
|
473 | |
|
|
474 | The event is simply the action string. This interface is assumed to |
|
|
475 | change slightly in the future. |
|
|
476 | |
|
|
477 | on_x_event $term, $event |
|
|
478 | Called on every X event received on the vt window (and possibly |
|
|
479 | other windows). Should only be used as a last resort. Most event |
|
|
480 | structure members are not passed. |
|
|
481 | |
|
|
482 | on_focus_in $term |
|
|
483 | Called whenever the window gets the keyboard focus, before |
|
|
484 | rxvt-unicode does focus in processing. |
|
|
485 | |
|
|
486 | on_focus_out $term |

499 | Called whenever the corresponding X event is received for the |
|
|
500 | terminal If the hook returns true, then the even will be ignored by |
|
|
501 | rxvt-unicode. |
|
|
502 | |
|
|
503 | The event is a hash with most values as named by Xlib (see the |
|
|
504 | XEvent manpage), with the additional members "row" and "col", which |
|
|
505 | are the (real, not screen-based) row and column under the mouse |
|
|
506 | cursor. |
|
|
507 | |

519 | Variables in the "urxvt" Package |
|
|
520 | $urxvt::LIBDIR |
|
|
521 | The rxvt-unicode library directory, where, among other things, the |
|
|
522 | perl modules and scripts are stored. |
|
|
523 | |
|
|
524 | $urxvt::RESCLASS, $urxvt::RESCLASS |
|
|
525 | The resource class and name rxvt-unicode uses to look up X |
|
|
526 | resources. |
|
|
527 | |
|
|
528 | $urxvt::RXVTNAME |
|
|
529 | The basename of the installed binaries, usually "urxvt". |
|
|
530 | |
|
|
531 | $urxvt::TERM |
|
|
532 | The current terminal. This variable stores the current "urxvt::term" |
|
|
533 | object, whenever a callback/hook is executing. |
|
|
534 | |
|
|
535 | @urxvt::TERM_INIT |
|
|
536 | All coderefs in this array will be called as methods of the next |
|
|
537 | newly created "urxvt::term" object (during the "on_init" phase). The |
|
|
538 | array gets cleared before the codereferences that were in it are |
|
|
539 | being executed, so coderefs can push themselves onto it again if |
|
|
540 | they so desire. |
|
|
541 | |
|
|
542 | This complements to the perl-eval commandline option, but gets |
|
|
543 | executed first. |
|
|
544 | |
|
|
545 | @urxvt::TERM_EXT |
|
|
546 | Works similar to @TERM_INIT, but contains perl package/class names, |
|
|
547 | which get registered as normal extensions after calling the hooks in |
|
|
548 | @TERM_INIT but before other extensions. Gets cleared just like |
|
|
549 | @TERM_INIT. |

|
|
570 | careful. Only term objects that have perl extensions attached will |

|
|
597 | |
|
|
598 | RENDITION |
|
|
599 | Rendition bitsets contain information about colour, font, font styles |
|
|
600 | and similar information for each screen cell. |
|
|
601 | |
|
|
602 | The following "macros" deal with changes in rendition sets. You should |
|
|
603 | never just create a bitset, you should always modify an existing one, as |
|
|
604 | they contain important information required for correct operation of |
|
|
605 | rxvt-unicode. |
|
|
606 | |
|
|
607 | $rend = urxvt::DEFAULT_RSTYLE |
|
|
608 | Returns the default rendition, as used when the terminal is starting |
|
|
609 | up or being reset. Useful as a base to start when creating |
|
|
610 | renditions. |
|
|
611 | |
|
|
612 | $rend = urxvt::OVERLAY_RSTYLE |
|
|
613 | Return the rendition mask used for overlays by default. |
|
|
614 | |
|
|
615 | $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline |
|
|
616 | Return the bit that enabled bold, italic, blink, reverse-video and |
|
|
617 | underline, respectively. To enable such a style, just logically OR |
|
|
618 | it into the bitset. |
|
|
619 | |
|
|
620 | $foreground = urxvt::GET_BASEFG $rend |
|
|
621 | $background = urxvt::GET_BASEBG $rend |
|
|
622 | Return the foreground/background colour index, respectively. |
|
|
623 | |
|
|
624 | $rend = urxvt::SET_FGCOLOR $rend, $new_colour |
|
|
625 | $rend = urxvt::SET_BGCOLOR $rend, $new_colour |
|
|
626 | $rend = urxvt::SET_COLOR $rend, $new_fg, $new_bg |
|
|
627 | Replace the foreground/background colour in the rendition mask with |
|
|
628 | the specified one. |
|
|
629 | |
|
|
630 | $value = urxvt::GET_CUSTOM $rend |
|
|
631 | Return the "custom" value: Every rendition has 5 bits for use by |
|
|
632 | extensions. They can be set and changed as you like and are |
|
|
633 | initially zero. |
|
|
634 | |
|
|
635 | $rend = urxvt::SET_CUSTOM $rend, $new_value |
|
|
636 | Change the custom value. |
|
|
637 | |
|
|
638 | The "urxvt::anyevent" Class |
|
|
639 | The sole purpose of this class is to deliver an interface to the |
|
|
640 | "AnyEvent" module - any module using it will work inside urxvt without |
|
|
641 | further programming. The only exception is that you cannot wait on |
|
|
642 | condition variables, but non-blocking condvar use is ok. What this means |
|
|
643 | is that you cannot use blocking APIs, but the non-blocking variant |
|
|
644 | should work. |
|
|
645 | |
136 | The "urxvt::term" Class |
646 | The "urxvt::term" Class |
|
|
647 | $term = new urxvt::term $envhashref, $rxvtname, [arg...] |
|
|
648 | Creates a new terminal, very similar as if you had started it with |
|
|
649 | system "$rxvtname, arg...". $envhashref must be a reference to a |
|
|
650 | %ENV-like hash which defines the environment of the new terminal. |
|
|
651 | |
|
|
652 | Croaks (and probably outputs an error message) if the new instance |
|
|
653 | couldn't be created. Returns "undef" if the new instance didn't |
|
|
654 | initialise perl, and the terminal object otherwise. The "init" and |
|
|
655 | "start" hooks will be called before this call returns, and are free |
|
|
656 | to refer to global data (which is race free). |
|
|
657 | |
|
|
658 | $term->destroy |
|
|
659 | Destroy the terminal object (close the window, free resources etc.). |
|
|
660 | Please note that rxvt will not exit as long as any event watchers |
|
|
661 | (timers, io watchers) are still active. |
|
|
662 | |
|
|
663 | $term->exec_async ($cmd[, @args]) |
|
|
664 | Works like the combination of the "fork"/"exec" builtins, which |
|
|
665 | executes ("starts") programs in the background. This function takes |
|
|
666 | care of setting the user environment before exec'ing the command |
|
|
667 | (e.g. "PATH") and should be preferred over explicit calls to "exec" |
|
|
668 | or "system". |
|
|
669 | |
|
|
670 | Returns the pid of the subprocess or "undef" on error. |
|
|
671 | |
|
|
672 | $isset = $term->option ($optval[, $set]) |
|
|
673 | Returns true if the option specified by $optval is enabled, and |
|
|
674 | optionally change it. All option values are stored by name in the |
|
|
675 | hash %urxvt::OPTION. Options not enabled in this binary are not in |
|
|
676 | the hash. |
|
|
677 | |
|
|
678 | Here is a a likely non-exhaustive list of option names, please see |

137 | $value = $term->resource ($name[, $newval]) |

785 | |
198 | $term->scr_overlay_set_char ($x, $y, $char, $rend = OVERLAY_RSTYLE) |
786 | The methods currently supported on "urxvt::overlay" objects are: |

|
|
200 | position. |
|
|
201 | |
787 | |
202 | $term->scr_overlay_set ($x, $y, $text) |
788 | $overlay->set ($x, $y, $text, $rend) |
203 | Write a string at the given position into the overlay. |
789 | Similar to "$term->ROW_t" and "$term->ROW_r" in that it puts |
|
|
790 | text in rxvt-unicode's special encoding and an array of |
|
|
791 | rendition values at a specific position inside the overlay. |

|
|
815 | $term->scr_xor_span ($beg_row, $beg_col, $end_row, $end_col[, $rstyle]) |
|
|
816 | XORs the rendition values in the given span with the provided value |
|
|
817 | (default: "RS_RVid"), which *MUST NOT* contain font styles. Useful |
|
|
818 | in refresh hooks to provide effects similar to the selection. |

819 | |
|
|
820 | $term->scr_xor_rect ($beg_row, $beg_col, $end_row, $end_col[, $rstyle1[, |
|
|
821 | $rstyle2]]) |
|
|
822 | Similar to "scr_xor_span", but xors a rectangle instead. Trailing |
|
|
823 | whitespace will additionally be xored with the $rstyle2, which |
|
|
824 | defaults to "RS_RVid | RS_Uline", which removes reverse video again |
|
|
825 | and underlines it instead. Both styles *MUST NOT* contain font |
|

|
|
832 | Write the given text string to the screen, as if output by the |
|
|
833 | application running inside the terminal. It may not contain command |
|
|
834 | sequences (escape codes), but is free to use line feeds, carriage |
|
|
835 | returns and tabs. The string is a normal text string, not in |
|
|
836 | locale-dependent encoding. |
|
|
837 | |
|
|
838 | Normally its not a good idea to use this function, as programs might |
|
|
839 | be confused by changes in cursor position or scrolling. Its useful |
|
|
840 | inside a "on_add_lines" hook, though. |
|
|
841 | |
|
|
842 | $term->scr_change_screen ($screen) |

|
|
844 | |
|
|
845 | $term->cmd_parse ($octets) |
|
|
846 | Similar to "scr_add_lines", but the argument must be in the |
|
|
847 | locale-specific encoding of the terminal and can contain command |
|
|
848 | sequences (escape codes) that will be interpreted. |

856 | $old_events = $term->pty_ev_events ([$new_events]) |
|
|
857 | Replaces the event mask of the pty watcher by the given event mask. |
|
|
858 | Can be used to suppress input and output handling to the pty/tty. |
|
|
859 | See the description of "urxvt::timer->events". Make sure to always |
|
|
860 | restore the previous value. |
|
|
861 | |
|
|
862 | $fd = $term->pty_fd |
|
|
863 | Returns the master file descriptor for the pty in use, or -1 if no |

|
864 | pty is used. |
|
|
865 | |
|

|
|
868 | |
|
|
869 | $windowid = $term->vt |

|
870 | Return the window id of the terminal window. |
|
|
871 | |
|
|
872 | $term->vt_emask_add ($x_event_mask) |
|
|
873 | Adds the specified events to the vt event mask. Useful e.g. when you |
|
|
874 | want to receive pointer events all the times: |

|
|
897 | |
|
|
898 | $x_display = $term->display_id |
|
|
899 | Return the DISPLAY used by rxvt-unicode. |
|
|
900 | |
|
|
901 | $lc_ctype = $term->locale |
|
|
902 | Returns the LC_CTYPE category string used by this rxvt-unicode. |
|
|
903 | |
|
|
904 | $env = $term->env |
|
|
905 | Returns a copy of the environment in effect for the terminal as a |
|
|
906 | hashref similar to "\%ENV". |
|

908 | $modifiermask = $term->ModLevel3Mask |
|
|
909 | $modifiermask = $term->ModMetaMask |
|
|
910 | $modifiermask = $term->ModNumLockMask |
|
|
911 | Return the modifier masks corresponding to the "ISO Level 3 Shift" |
|
|
912 | (often AltGr), the meta key (often Alt) and the num lock key, if |
|
|
913 | applicable. |
|
|
914 | |
|
|
915 | $screen = $term->current_screen |
|
|
916 | Returns the currently displayed screen (0 primary, 1 secondary). |
|
|
917 | |
|
|
918 | $cursor_is_hidden = $term->hidden_cursor |
|
|
919 | Returns wether the cursor is currently hidden or not. |
|
|
920 | |
|
|
921 | $view_start = $term->view_start ([$newvalue]) |
|
|
922 | Returns the row number of the topmost displayed line. Maximum value |
|
|
923 | is 0, which displays the normal terminal contents. Lower values |
|
|
924 | scroll this many lines into the scrollback buffer. |
|
|
925 | |
|
|
926 | $term->want_refresh |
|
|
927 | Requests a screen refresh. At the next opportunity, rxvt-unicode |
|
|
928 | will compare the on-screen display with its stored representation. |
|
|
929 | If they differ, it redraws the differences. |
|
|
930 | |
|
|
931 | Used after changing terminal contents to display them. |
|
|
932 | |
|
|
933 | $text = $term->ROW_t ($row_number[, $new_text[, $start_col]]) |
|
|
934 | Returns the text of the entire row with number $row_number. Row 0 is |
|
|
935 | the topmost terminal line, row "$term->$ncol-1" is the bottommost |
|
|
936 | terminal line. The scrollback buffer starts at line -1 and extends |
|
|
937 | to line "-$term->nsaved". Nothing will be returned if a nonexistent |
|
|
938 | line is requested. |
|
|
939 | |
|
|
940 | If $new_text is specified, it will replace characters in the current |
|
|
941 | line, starting at column $start_col (default 0), which is useful to |
|
|
942 | replace only parts of a line. The font index in the rendition will |
|
|
943 | automatically be updated. |
|
|
944 | |
|
|
945 | $text is in a special encoding: tabs and wide characters that use |
|
|
946 | more than one cell when displayed are padded with $urxvt::NOCHAR |
|
|
947 | (chr 65535) characters. Characters with combining characters and |
|
|
948 | other characters that do not fit into the normal tetx encoding will |
|
|
949 | be replaced with characters in the private use area. |
|
|
950 | |
|
|
951 | You have to obey this encoding when changing text. The advantage is |
|
|
952 | that "substr" and similar functions work on screen cells and not on |
|
|
953 | characters. |
|
|
954 | |
|
|
955 | The methods "$term->special_encode" and "$term->special_decode" can |
|
|
956 | be used to convert normal strings into this encoding and vice versa. |
|
|
957 | |
|
|
958 | $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]]) |
|
|
959 | Like "$term->ROW_t", but returns an arrayref with rendition bitsets. |
|
|
960 | Rendition bitsets contain information about colour, font, font |
|
|
961 | styles and similar information. See also "$term->ROW_t". |
|
|
962 | |
|
|
963 | When setting rendition, the font mask will be ignored. |
|
|
964 | |
|
|
965 | See the section on RENDITION, above. |
|
|
966 | |
|
|
967 | $length = $term->ROW_l ($row_number[, $new_length]) |
|
|
968 | Returns the number of screen cells that are in use ("the line |
|
|
969 | length"). Unlike the urxvt core, this returns "$term->ncol" if the |
|
|
970 | line is joined with the following one. |
|
|
971 | |
|
|
972 | $bool = $term->is_longer ($row_number) |
|
|
973 | Returns true if the row is part of a multiple-row logical "line" |
|
|
974 | (i.e. joined with the following row), which means all characters are |
|
|
975 | in use and it is continued on the next row (and possibly a |
|
|
976 | continuation of the previous row(s)). |
|
|
977 | |
|
|
978 | $line = $term->line ($row_number) |
|
|
979 | Create and return a new "urxvt::line" object that stores information |
|
|
980 | about the logical line that row $row_number is part of. It supports |
|
|
981 | the following methods: |
|
|
982 | |
|
|
983 | $text = $line->t ([$new_text]) |
|
|
984 | Returns or replaces the full text of the line, similar to |
|
|
985 | "ROW_t" |
|
|
986 | |
|
|
987 | $rend = $line->r ([$new_rend]) |
|
|
988 | Returns or replaces the full rendition array of the line, |
|
|
989 | similar to "ROW_r" |
|
|
990 | |
|
|
991 | $length = $line->l |
|
|
992 | Returns the length of the line in cells, similar to "ROW_l". |
|
|
993 | |
|
|
994 | $rownum = $line->beg |
|
|
995 | $rownum = $line->end |
|
|
996 | Return the row number of the first/last row of the line, |
|
|
997 | respectively. |
|
|
998 | |
|
|
999 | $offset = $line->offset_of ($row, $col) |
|
|
1000 | Returns the character offset of the given row|col pair within |
|
|
1001 | the logical line. Works for rows outside the line, too, and |
|
|
1002 | returns corresponding offsets outside the string. |
|
|
1003 | |
