DESCRIPTION |
17 |
Everytime a terminal object gets created, extension scripts specified |
18 |
via the "perl" resource are loaded and associated with it. |
19 |
|
20 |
Scripts are compiled in a 'use strict' and 'use utf8' environment, and |
21 |
thus must be encoded as UTF-8. |
22 |
|
23 |
Each script will only ever be loaded once, even in rxvtd, where scripts |
24 |
will be shared (but not enabled) for all terminals. |
25 |
|
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 |
You can look at the source of the selection extension to see more |
64 |
interesting uses, such as parsing a line from beginning to end. |
65 |
|
66 |
This extension also offers following bindable keyboard commands: |
67 |
|
68 |
rot13 |
69 |
Rot-13 the selection when activated. Used via keyboard trigger: |
70 |
|
71 |
URxvt.keysym.C-M-r: perl:selection:rot13 |
72 |
|
73 |
option-popup (enabled by default) |
74 |
Binds a popup menu to Ctrl-Button2 that lets you toggle (some) |
75 |
options at runtime. |
76 |
|
77 |
selection-popup (enabled by default) |
78 |
Binds a popup menu to Ctrl-Button3 that lets you convert the |
79 |
selection text into various other formats/action (such as uri |
80 |
unescaping, perl evaluation, web-browser starting etc.), depending |
81 |
on content. |
82 |
|
83 |
Other extensions can extend this popup menu by pushing a code |
84 |
reference onto "@{ $term-"{selection_popup_hook} }>, that is called |
85 |
whenever the popup is displayed. |
86 |
|
87 |
It's sole argument is the popup menu, which can be modified. The |
88 |
selection is in $_, which can be used to decide wether to add |
89 |
something or not. It should either return nothing or a string and a |
90 |
code reference. The string will be used as button text and the code |
91 |
reference will be called when the button gets activated and should |
92 |
transform $_. |
93 |
|
94 |
The following will add an entry "a to b" that transforms all "a"s in |
95 |
the selection to "b"s, but only if the selection currently contains |
96 |
any "a"s: |
97 |
|
98 |
push @{ $self->{term}{selection_popup_hook} }, sub { |
99 |
/a/ ? ("a to be" => sub { s/a/b/g } |
100 |
: () |
101 |
}; |
102 |
|
103 |
searchable-scrollback<hotkey> (enabled by default) |
104 |
Adds regex search functionality to the scrollback buffer, triggered |
105 |
by a hotkey (default: "M-s"). While in search mode, normal terminal |
106 |
input/output is suspended and a regex is displayed at the bottom of |
107 |
the screen. |
108 |
|
109 |
Inputting characters appends them to the regex and continues |
110 |
incremental search. "BackSpace" removes a character from the regex, |
111 |
"Up" and "Down" search upwards/downwards in the scrollback buffer, |
112 |
"End" jumps to the bottom. "Escape" leaves search mode and returns |
113 |
to the point where search was started, while "Enter" or "Return" |
114 |
stay at the current position and additionally stores the first match |
115 |
in the current line into the primary selection. |
116 |
|
117 |
readline (enabled by default) |
118 |
A support package that tries to make editing with readline easier. |
119 |
At the moment, it reacts to clicking with the left mouse button by |
120 |
trying to move the text cursor to this position. It does so by |
121 |
generating as many cursor-left or cursor-right keypresses as |
122 |
required (the this only works for programs that correctly support |
123 |
wide characters). |
124 |
|
125 |
To avoid too many false positives, this is only done when: |
126 |
|
127 |
- the mouse is on the same (multi-row-) line as the text cursor. |
128 |
- the primary screen is currently being displayed. |
129 |
- the text cursor is visible. |
130 |
|
131 |
The normal selection mechanism isn't disabled, so quick successive |
132 |
clicks might interfere with selection creation in harmless ways. |
133 |
|
134 |
selection-autotransform |
135 |
This selection allows you to do automatic transforms on a selection |
136 |
whenever a selection is made. |
137 |
|
138 |
It works by specifying perl snippets (most useful is a single "s///" |
139 |
operator) that modify $_ as resources: |
140 |
|
141 |
URxvt.selection-autotransform.0: transform |
142 |
URxvt.selection-autotransform.1: transform |
143 |
... |
144 |
|
145 |
For example, the following will transform selections of the form |
146 |
"filename:number", often seen in compiler messages, into "vi |
147 |
+$filename $word": |
148 |
|
149 |
URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/ |
150 |
|
151 |
And this example matches the same,but replaces it with vi-commands |
152 |
you can paste directly into your (vi :) editor: |
153 |
|
154 |
URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/ |
155 |
|
156 |
Of course, this can be modified to suit your needs and your editor |
157 |
:) |
158 |
|
159 |
To expand the example above to typical perl error messages ("XXX at |
160 |
FILENAME line YYY."), you need a slightly more elaborate solution: |
161 |
|
162 |
URxvt.selection.pattern-0: ( at .*? line \\d+[,.]) |
163 |
URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/ |
164 |
|
165 |
The first line tells the selection code to treat the unchanging part |
166 |
of every error message as a selection pattern, and the second line |
167 |
transforms the message into vi commands to load the file. |
168 |
|
169 |
tabbed |
170 |
This transforms the terminal into a tabbar with additional |
171 |
terminals, that is, it implements what is commonly refered to as |
172 |
"tabbed terminal". The topmost line displays a "[NEW]" button, |
173 |
which, when clicked, will add a new tab, followed by one button per |
174 |
tab. |
175 |
|
176 |
Clicking a button will activate that tab. Pressing Shift-Left and |
177 |
Shift-Right will switch to the tab left or right of the current one, |
178 |
while Shift-Down creates a new tab. |
179 |
|
180 |
mark-urls |
181 |
Uses per-line display filtering ("on_line_update") to underline urls |
182 |
and make them clickable. When middle-clicked, the program specified |
183 |
in the resource "urlLauncher" (default "x-www-browser") will be |
184 |
started with the URL as first argument. |
185 |
|
186 |
automove-background |
187 |
This is basically a one-line extension that dynamically changes the |
188 |
background pixmap offset to the window position, in effect creating |
189 |
the same effect as pseudo transparency with a custom pixmap. No |
190 |
scaling is supported in this mode. Exmaple: |
191 |
|
192 |
rxvt -pixmap background.xpm -pe automove-background |
193 |
|
194 |
block-graphics-to-ascii |
195 |
A not very useful example of filtering all text output to the |
196 |
terminal, by replacing all line-drawing characters (U+2500 .. |
197 |
U+259F) by a similar-looking ascii character. |
198 |
|
199 |
digital-clock |
200 |
Displays a digital clock using the built-in overlay. |
201 |
|
202 |
example-refresh-hooks |
203 |
Displays a very simple digital clock in the upper right corner of |
204 |
the window. Illustrates overwriting the refresh callbacks to create |
205 |
your own overlays or changes. |
206 |
|
207 |
selection-pastebin |
208 |
This is a little rarely useful extension that Uploads the selection |
209 |
as textfile to a remote site (or does other things). (The |
210 |
implementation is not currently secure for use in a multiuser |
211 |
environment as it writes to /tmp directly.). |
212 |
|
213 |
It listens to the "selection-pastebin:remote-pastebin" keyboard |
214 |
command, i.e. |
215 |
|
216 |
URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
217 |
|
218 |
Pressing this combination runs a command with "%" replaced by the |
219 |
name of the textfile. This command can be set via a resource: |
220 |
|
221 |
URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/. |
222 |
|
223 |
And the default is likely not useful to anybody but the few people |
224 |
around here :) |
225 |
|
226 |
The name of the textfile is the hex encoded md5 sum of the |
227 |
selection, so the same content should lead to the same filename. |
228 |
|
229 |
After a successful upload the selection will be replaced by the text |
230 |
given in the "selection-pastebin-url" resource (again, the % is the |
231 |
placeholder for the filename): |
232 |
|
233 |
URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/% |
234 |
|
235 |
API DOCUMENTATION |
236 |
General API Considerations |
237 |
All objects (such as terminals, time watchers etc.) are typical |
238 |
reference-to-hash objects. The hash can be used to store anything you |
239 |
like. All members starting with an underscore (such as "_ptr" or |
240 |
"_hook") are reserved for internal uses and MUST NOT be accessed or |
241 |
modified). |
242 |
|
243 |
When objects are destroyed on the C++ side, the perl object hashes are |
244 |
emptied, so its best to store related objects such as time watchers and |
245 |
the like inside the terminal object so they get destroyed as soon as the |
246 |
terminal is destroyed. |
247 |
|
248 |
Argument names also often indicate the type of a parameter. Here are |
249 |
some hints on what they mean: |
250 |
|
251 |
$text |
252 |
Rxvt-unicodes special way of encoding text, where one "unicode" |
253 |
character always represents one screen cell. See ROW_t for a |
254 |
discussion of this format. |
255 |
|
256 |
$string |
257 |
A perl text string, with an emphasis on *text*. It can store all |
258 |
unicode characters and is to be distinguished with text encoded in a |
259 |
specific encoding (often locale-specific) and binary data. |
260 |
|
261 |
$octets |
262 |
Either binary data or - more common - a text string encoded in a |
263 |
locale-specific way. |
264 |
|
265 |
Extension Objects |
266 |
Very perl extension is a perl class. A separate perl object is created |
267 |
for each terminal and each extension and passed as the first parameter |
268 |
to hooks. So extensions can use their $self object without having to |
269 |
think about other extensions, with the exception of methods and members |
270 |
that begin with an underscore character "_": these are reserved for |
271 |
internal use. |
272 |
|
273 |
Although it isn't a "urxvt::term" object, you can call all methods of |
274 |
the "urxvt::term" class on this object. |
275 |
|
276 |
It has the following methods and data members: |
277 |
|
278 |
$urxvt_term = $self->{term} |
279 |
Returns the "urxvt::term" object associated with this instance of |
280 |
the extension. This member *must not* be changed in any way. |
281 |
|
282 |
$self->enable ($hook_name => $cb, [$hook_name => $cb..]) |
283 |
Dynamically enable the given hooks (named without the "on_" prefix) |
284 |
for this extension, replacing any previous hook. This is useful when |
285 |
you want to overwrite time-critical hooks only temporarily. |
286 |
|
287 |
$self->disable ($hook_name[, $hook_name..]) |
288 |
Dynamically disable the given hooks. |
289 |
|
290 |
Hooks |
291 |
The following subroutines can be declared in extension files, and will |
292 |
be called whenever the relevant event happens. |
293 |
|
294 |
The first argument passed to them is an extension oject as described in |
295 |
the in the "Extension Objects" section. |
296 |
|
297 |
All of these hooks must return a boolean value. If any of the called |
298 |
hooks returns true, then the event counts as being *consumed*, and the |
299 |
relevant action might not be carried out by the C++ code. |
300 |
|
301 |
*When in doubt, return a false value (preferably "()").* |
302 |
|
303 |
on_init $term |
304 |
Called after a new terminal object has been initialized, but before |
305 |
windows are created or the command gets run. Most methods are unsafe |
306 |
to call or deliver senseless data, as terminal size and other |
307 |
characteristics have not yet been determined. You can safely query |
308 |
and change resources and options, though. For many purposes the |
309 |
"on_start" hook is a better place. |
310 |
|
311 |
on_start $term |
312 |
Called at the very end of initialisation of a new terminal, just |
313 |
before trying to map (display) the toplevel and returning to the |
314 |
mainloop. |
315 |
|
316 |
on_destroy $term |
317 |
Called whenever something tries to destroy terminal, before doing |
318 |
anything yet. If this hook returns true, then destruction is |
319 |
skipped, but this is rarely a good idea. |
320 |
|
321 |
on_reset $term |
322 |
Called after the screen is "reset" for any reason, such as resizing |
323 |
or control sequences. Here is where you can react on changes to |
324 |
size-related variables. |
325 |
|
326 |
on_child_start $term, $pid |
327 |
Called just after the child process has been "fork"ed. |
328 |
|
329 |
on_child_exit $term, $status |
330 |
Called just after the child process has exited. $status is the |
331 |
status from "waitpid". |
332 |
|
333 |
on_sel_make $term, $eventtime |
334 |
Called whenever a selection has been made by the user, but before |
335 |
the selection text is copied, so changes to the beginning, end or |
336 |
type of the selection will be honored. |
337 |
|
338 |
Returning a true value aborts selection making by urxvt, in which |
339 |
case you have to make a selection yourself by calling |
340 |
"$term->selection_grab". |
341 |
|
342 |
on_sel_grab $term, $eventtime |
343 |
Called whenever a selection has been copied, but before the |
344 |
selection is requested from the server. The selection text can be |
345 |
queried and changed by calling "$term->selection". |
346 |
|
347 |
Returning a true value aborts selection grabbing. It will still be |
348 |
hilighted. |
349 |
|
350 |
on_sel_extend $term |
351 |
Called whenever the user tries to extend the selection (e.g. with a |
352 |
double click) and is either supposed to return false (normal |
353 |
operation), or should extend the selection itelf and return true to |
354 |
suppress the built-in processing. This can happen multiple times, as |
355 |
long as the callback returns true, it will be called on every |
356 |
further click by the user and is supposed to enlarge the selection |
357 |
more and more, if possible. |
358 |
|
359 |
See the selection example extension. |
360 |
|
361 |
on_view_change $term, $offset |
362 |
Called whenever the view offset changes, i..e the user or program |
363 |
scrolls. Offset 0 means display the normal terminal, positive values |
364 |
show this many lines of scrollback. |
365 |
|
366 |
on_scroll_back $term, $lines, $saved |
367 |
Called whenever lines scroll out of the terminal area into the |
368 |
scrollback buffer. $lines is the number of lines scrolled out and |
369 |
may be larger than the scroll back buffer or the terminal. |
370 |
|
371 |
It is called before lines are scrolled out (so rows 0 .. min ($lines |
372 |
- 1, $nrow - 1) represent the lines to be scrolled out). $saved is |
373 |
the total number of lines that will be in the scrollback buffer. |
374 |
|
375 |
on_osc_seq $term, $string |
376 |
Called whenever the ESC ] 777 ; string ST command sequence (OSC = |
377 |
operating system command) is processed. Cursor position and other |
378 |
state information is up-to-date when this happens. For |
379 |
interoperability, the string should start with the extension name |
380 |
and a colon, to distinguish it from commands for other extensions, |
381 |
and this might be enforced in the future. |
382 |
|
383 |
Be careful not ever to trust (in a security sense) the data you |
384 |
receive, as its source can not easily be controleld (e-mail content, |
385 |
messages from other users on the same system etc.). |
386 |
|
387 |
on_add_lines $term, $string |
388 |
Called whenever text is about to be output, with the text as |
389 |
argument. You can filter/change and output the text yourself by |
390 |
returning a true value and calling "$term->scr_add_lines" yourself. |
391 |
Please note that this might be very slow, however, as your hook is |
392 |
called for all text being output. |
393 |
|
394 |
on_tt_write $term, $octets |
395 |
Called whenever some data is written to the tty/pty and can be used |
396 |
to suppress or filter tty input. |
397 |
|
398 |
on_line_update $term, $row |
399 |
Called whenever a line was updated or changed. Can be used to filter |
400 |
screen output (e.g. underline urls or other useless stuff). Only |
401 |
lines that are being shown will be filtered, and, due to performance |
402 |
reasons, not always immediately. |
403 |
|
404 |
The row number is always the topmost row of the line if the line |
405 |
spans multiple rows. |
406 |
|
407 |
Please note that, if you change the line, then the hook might get |
408 |
called later with the already-modified line (e.g. if unrelated parts |
409 |
change), so you cannot just toggle rendition bits, but only set |
410 |
them. |
411 |
|
412 |
on_refresh_begin $term |
413 |
Called just before the screen gets redrawn. Can be used for overlay |
414 |
or similar effects by modify terminal contents in refresh_begin, and |
415 |
restoring them in refresh_end. The built-in overlay and selection |
416 |
display code is run after this hook, and takes precedence. |
417 |
|
418 |
on_refresh_end $term |
419 |
Called just after the screen gets redrawn. See "on_refresh_begin". |
420 |
|
421 |
on_keyboard_command $term, $string |
422 |
Called whenever the user presses a key combination that has a |
423 |
"perl:string" action bound to it (see description of the keysym |
424 |
resource in the rxvt(1) manpage). |
425 |
|
426 |
on_x_event $term, $event |
427 |
Called on every X event received on the vt window (and possibly |
428 |
other windows). Should only be used as a last resort. Most event |
429 |
structure members are not passed. |
430 |
|
431 |
on_focus_in $term |
432 |
Called whenever the window gets the keyboard focus, before |
433 |
rxvt-unicode does focus in processing. |
434 |
|
435 |
on_focus_out $term |
436 |
Called wheneever the window loses keyboard focus, before |
437 |
rxvt-unicode does focus out processing. |
438 |
|
439 |
on_configure_notify $term, $event |
440 |
on_property_notify $term, $event |
441 |
on_key_press $term, $event, $keysym, $octets |
442 |
on_key_release $term, $event, $keysym |

on_motion_notify $term, $event |
446 |
on_map_notify $term, $event |
447 |
on_unmap_notify $term, $event |
448 |
Called whenever the corresponding X event is received for the |
449 |
terminal If the hook returns true, then the even will be ignored by |
450 |
rxvt-unicode. |
451 |
|
452 |
The event is a hash with most values as named by Xlib (see the |
453 |
XEvent manpage), with the additional members "row" and "col", which |
454 |
are the (real, not screen-based) row and column under the mouse |
455 |
cursor. |
456 |
|
457 |
"on_key_press" additionally receives the string rxvt-unicode would |
458 |
output, if any, in locale-specific encoding. |

on_client_message $term, $event |
463 |
on_wm_protocols $term, $event |
464 |
on_wm_delete_window $term, $event |
465 |
Called when various types of ClientMessage events are received (all |
466 |
with format=32, WM_PROTOCOLS or WM_PROTOCOLS:WM_DELETE_WINDOW). |
467 |
|
468 |
Variables in the "urxvt" Package |
469 |
$urxvt::LIBDIR |
470 |
The rxvt-unicode library directory, where, among other things, the |
471 |
perl modules and scripts are stored. |
472 |
|
473 |
$urxvt::RESCLASS, $urxvt::RESCLASS |
474 |
The resource class and name rxvt-unicode uses to look up X |
475 |
resources. |
476 |
|
477 |
$urxvt::RXVTNAME |
478 |
The basename of the installed binaries, usually "urxvt". |
479 |
|
480 |
$urxvt::TERM |
481 |
The current terminal. This variable stores the current "urxvt::term" |
482 |
object, whenever a callback/hook is executing. |
483 |
|
484 |
@urxvt::TERM_INIT |
485 |
All coderefs in this array will be called as methods of the next |
486 |
newly created "urxvt::term" object (during the "on_init" phase). The |
487 |
array gets cleared before the codereferences that were in it are |
488 |
being executed, so coderefs can push themselves onto it again if |
489 |
they so desire. |
490 |
|
491 |
This complements to the perl-eval commandline option, but gets |
492 |
executed first. |
493 |
|
494 |
@urxvt::TERM_EXT |
495 |
Works similar to @TERM_INIT, but contains perl package/class names, |
496 |
which get registered as normal extensions after calling the hooks in |
497 |
@TERM_INIT but before other extensions. Gets cleared just like |
498 |
@TERM_INIT. |
499 |
|
500 |
Functions in the "urxvt" Package |
501 |
urxvt::fatal $errormessage |
502 |
Fatally aborts execution with the given error message. Avoid at all |
503 |
costs! The only time this is acceptable is when the terminal process |
504 |
starts up. |
505 |
|
506 |
urxvt::warn $string |
507 |
Calls "rxvt_warn" with the given string which should not include a |
508 |
newline. The module also overwrites the "warn" builtin with a |
509 |
function that calls this function. |
510 |
|
511 |
Using this function has the advantage that its output ends up in the |
512 |
correct place, e.g. on stderr of the connecting urxvtc client. |
513 |
|
514 |
Messages have a size limit of 1023 bytes currently. |
515 |
|
516 |
$time = urxvt::NOW |
517 |
Returns the "current time" (as per the event loop). |

538 |
Various constants for use in X calls and event processing. |
539 |
|
540 |
RENDITION |
541 |
Rendition bitsets contain information about colour, font, font styles |
542 |
and similar information for each screen cell. |
543 |
|
544 |
The following "macros" deal with changes in rendition sets. You should |
545 |
never just create a bitset, you should always modify an existing one, as |
546 |
they contain important information required for correct operation of |
547 |
rxvt-unicode. |
548 |
|
549 |
$rend = urxvt::DEFAULT_RSTYLE |
550 |
Returns the default rendition, as used when the terminal is starting |
551 |
up or being reset. Useful as a base to start when creating |
552 |
renditions. |
553 |
|
554 |
$rend = urxvt::OVERLAY_RSTYLE |
555 |
Return the rendition mask used for overlays by default. |
556 |
|
557 |
$rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline |
558 |
Return the bit that enabled bold, italic, blink, reverse-video and |
559 |
underline, respectively. To enable such a style, just logically OR |
560 |
it into the bitset. |
561 |
|
562 |
$foreground = urxvt::GET_BASEFG $rend |
563 |
$background = urxvt::GET_BASEBG $rend |
564 |
Return the foreground/background colour index, respectively. |
565 |
|
566 |
$rend = urxvt::SET_FGCOLOR $rend, $new_colour |
567 |
$rend = urxvt::SET_BGCOLOR $rend, $new_colour |
568 |
Replace the foreground/background colour in the rendition mask with |
569 |
the specified one. |
570 |
|
571 |
$value = urxvt::GET_CUSTOM $rend |
572 |
Return the "custom" value: Every rendition has 5 bits for use by |
573 |
extensions. They can be set and changed as you like and are |
574 |
initially zero. |
575 |
|
576 |
$rend = urxvt::SET_CUSTOM $rend, $new_value |
577 |
Change the custom value. |
578 |
|
579 |
The "urxvt::anyevent" Class |
580 |
The sole purpose of this class is to deliver an interface to the |
581 |
"AnyEvent" module - any module using it will work inside urxvt without |
582 |
further programming. The only exception is that you cannot wait on |
583 |
condition variables, but non-blocking condvar use is ok. What this means |
584 |
is that you cannot use blocking APIs, but the non-blocking variant |
585 |
should work. |
586 |
|
587 |
The "urxvt::term" Class |
588 |
$term = new urxvt::term $envhashref, $rxvtname, [arg...] |
589 |
Creates a new terminal, very similar as if you had started it with |
590 |
system "$rxvtname, arg...". $envhashref must be a reference to a |
591 |
%ENV-like hash which defines the environment of the new terminal. |
592 |
|
593 |
Croaks (and probably outputs an error message) if the new instance |
594 |
couldn't be created. Returns "undef" if the new instance didn't |
595 |
initialise perl, and the terminal object otherwise. The "init" and |
596 |
"start" hooks will be called during this call. |
597 |
|
598 |
$term->destroy |
599 |
Destroy the terminal object (close the window, free resources etc.). |
600 |
Please note that rxvt will not exit as long as any event watchers |
601 |
(timers, io watchers) are still active. |
602 |
|
603 |
$term->exec_async ($cmd[, @args]) |
604 |
Works like the combination of the "fork"/"exec" builtins, which |
605 |
executes ("starts") programs in the background. This function takes |
606 |
care of setting the user environment before exec'ing the command |
607 |
(e.g. "PATH") and should be preferred over explicit calls to "exec" |
608 |
or "system". |
609 |
|
610 |
Returns the pid of the subprocess or "undef" on error. |
611 |
|
612 |
$isset = $term->option ($optval[, $set]) |
613 |
Returns true if the option specified by $optval is enabled, and |
614 |
optionally change it. All option values are stored by name in the |
615 |
hash %urxvt::OPTION. Options not enabled in this binary are not in |
616 |
the hash. |
617 |
|
618 |
Here is a a likely non-exhaustive list of option names, please see |
619 |
the source file /src/optinc.h to see the actual list: |

627 |
|
628 |
$value = $term->resource ($name[, $newval]) |
629 |
Returns the current resource value associated with a given name and |
630 |
optionally sets a new value. Setting values is most useful in the |
631 |
"init" hook. Unset resources are returned and accepted as "undef". |
632 |
|
633 |
The new value must be properly encoded to a suitable character |
634 |
encoding before passing it to this method. Similarly, the returned |
635 |
value may need to be converted from the used encoding to text. |
636 |
|
637 |
Resource names are as defined in src/rsinc.h. Colours can be |
638 |
specified as resource names of the form "color+<index>", e.g. |
639 |
"color+5". (will likely change). |
640 |
|
641 |
Please note that resource strings will currently only be freed when |
642 |
the terminal is destroyed, so changing options frequently will eat |
643 |
memory. |
644 |
|
645 |
Here is a a likely non-exhaustive list of resource names, not all of |
646 |
which are supported in every build, please see the source file |

$value = $term->x_resource ($pattern) |
664 |
Returns the X-Resource for the given pattern, excluding the program |
665 |
or class name, i.e. "$term->x_resource ("boldFont")" should return |
666 |
the same value as used by this instance of rxvt-unicode. Returns |
667 |
"undef" if no resource with that pattern exists. |
668 |
|
669 |
This method should only be called during the "on_start" hook, as |
670 |
there is only one resource database per display, and later |
671 |
invocations might return the wrong resources. |
672 |
|
673 |
$success = $term->parse_keysym ($keysym_spec, $command_string) |
674 |
Adds a keymap translation exactly as specified via a resource. See |
675 |
the "keysym" resource in the rxvt(1) manpage. |
676 |
|
677 |
$rend = $term->rstyle ([$new_rstyle]) |
678 |
Return and optionally change the current rendition. Text that is |
679 |
output by the terminal application will use this style. |
680 |
|
681 |
($row, $col) = $term->screen_cur ([$row, $col]) |
682 |
Return the current coordinates of the text cursor position and |
683 |
optionally set it (which is usually bad as applications don't expect |
684 |
that). |
685 |
|
686 |
($row, $col) = $term->selection_mark ([$row, $col]) |
687 |
($row, $col) = $term->selection_beg ([$row, $col]) |
688 |
($row, $col) = $term->selection_end ([$row, $col]) |
689 |
Return the current values of the selection mark, begin or end |
690 |
positions, and optionally set them to new values. |
691 |
|
692 |
$term->selection_make ($eventtime[, $rectangular]) |
693 |
Tries to make a selection as set by "selection_beg" and |
694 |
"selection_end". If $rectangular is true (default: false), a |
695 |
rectangular selection will be made. This is the prefered function to |
696 |
make a selection. |
697 |
|
698 |
$success = $term->selection_grab ($eventtime) |
699 |
Try to request the primary selection text from the server (for |
700 |
example, as set by the next method). No visual feedback will be |
701 |
given. This function is mostly useful from within "on_sel_grab" |
702 |
hooks. |
703 |
|
704 |
$oldtext = $term->selection ([$newtext]) |
705 |
Return the current selection text and optionally replace it by |
706 |
$newtext. |
707 |
|
708 |
$term->overlay_simple ($x, $y, $text) |
709 |
Create a simple multi-line overlay box. See the next method for |
710 |
details. |
711 |
|
712 |
$term->overlay ($x, $y, $width, $height[, $rstyle[, $border]]) |
713 |
Create a new (empty) overlay at the given position with the given |
714 |
width/height. $rstyle defines the initial rendition style (default: |
715 |
"OVERLAY_RSTYLE"). |
716 |
|
717 |
If $border is 2 (default), then a decorative border will be put |
718 |
around the box. |
719 |
|
720 |
If either $x or $y is negative, then this is counted from the |
721 |
right/bottom side, respectively. |
722 |
|
723 |
This method returns an urxvt::overlay object. The overlay will be |
724 |
visible as long as the perl object is referenced. |
725 |
|
726 |
The methods currently supported on "urxvt::overlay" objects are: |
727 |
|
728 |
$overlay->set ($x, $y, $text, $rend) |
729 |
Similar to "$term->ROW_t" and "$term->ROW_r" in that it puts |
730 |
text in rxvt-unicode's special encoding and an array of |
731 |
rendition values at a specific position inside the overlay. |
732 |
|
733 |
$overlay->hide |
734 |
If visible, hide the overlay, but do not destroy it. |
735 |
|
736 |
$overlay->show |
737 |
If hidden, display the overlay again. |
738 |
|
739 |
$popup = $term->popup ($event) |
740 |
Creates a new "urxvt::popup" object that implements a popup menu. |
741 |
The $event *must* be the event causing the menu to pop up (a button |
742 |
event, currently). |
743 |
|
744 |
$cellwidth = $term->strwidth ($string) |
745 |
Returns the number of screen-cells this string would need. Correctly |
746 |
accounts for wide and combining characters. |
747 |
|
748 |
$octets = $term->locale_encode ($string) |
749 |
Convert the given text string into the corresponding locale |
750 |
encoding. |
751 |
|
752 |
$string = $term->locale_decode ($octets) |
753 |
Convert the given locale-encoded octets into a perl string. |
754 |
|
755 |
$term->scr_xor_span ($beg_row, $beg_col, $end_row, $end_col[, $rstyle]) |
756 |
XORs the rendition values in the given span with the provided value |
757 |
(default: "RS_RVid"), which *MUST NOT* contain font styles. Useful |
758 |
in refresh hooks to provide effects similar to the selection. |
759 |
|
760 |
$term->scr_xor_rect ($beg_row, $beg_col, $end_row, $end_col[, $rstyle1[, |
761 |
$rstyle2]]) |
762 |
Similar to "scr_xor_span", but xors a rectangle instead. Trailing |
763 |
whitespace will additionally be xored with the $rstyle2, which |
764 |
defaults to "RS_RVid | RS_Uline", which removes reverse video again |
765 |
and underlines it instead. Both styles *MUST NOT* contain font |
766 |
styles. |
767 |
|
768 |
$term->scr_bell |
769 |
Ring the bell! |
770 |
|
771 |
$term->scr_add_lines ($string) |
772 |
Write the given text string to the screen, as if output by the |
773 |
application running inside the terminal. It may not contain command |
774 |
sequences (escape codes), but is free to use line feeds, carriage |
775 |
returns and tabs. The string is a normal text string, not in |
776 |
locale-dependent encoding. |
777 |
|
778 |
Normally its not a good idea to use this function, as programs might |
779 |
be confused by changes in cursor position or scrolling. Its useful |
780 |
inside a "on_add_lines" hook, though. |
781 |
|
782 |
$term->scr_change_screen ($screen) |
783 |
Switch to given screen - 0 primary, 1 secondary. |
784 |
|
785 |
$term->cmd_parse ($octets) |
786 |
Similar to "scr_add_lines", but the argument must be in the |
787 |
locale-specific encoding of the terminal and can contain command |
788 |
sequences (escape codes) that will be interpreted. |
789 |
|
790 |
$term->tt_write ($octets) |
791 |
Write the octets given in $data to the tty (i.e. as program input). |
792 |
To pass characters instead of octets, you should convert your |
793 |
strings first to the locale-specific encoding using |
794 |
"$term->locale_encode". |
795 |
|
796 |
$old_events = $term->pty_ev_events ([$new_events]) |
797 |
Replaces the event mask of the pty watcher by the given event mask. |
798 |
Can be used to suppress input and output handling to the pty/tty. |
799 |
See the description of "urxvt::timer->events". Make sure to always |
800 |
restore the previous value. |
801 |
|
802 |
$windowid = $term->parent |
803 |
Return the window id of the toplevel window. |
804 |
|
805 |
$windowid = $term->vt |
806 |
Return the window id of the terminal window. |
807 |
|
808 |
$term->vt_emask_add ($x_event_mask) |
809 |
Adds the specified events to the vt event mask. Useful e.g. when you |
810 |
want to receive pointer events all the times: |
811 |
|
812 |
$term->vt_emask_add (urxvt::PointerMotionMask); |
813 |
|
814 |
$window_width = $term->width |
815 |
$window_height = $term->height |
816 |
$font_width = $term->fwidth |
817 |
$font_height = $term->fheight |
818 |
$font_ascent = $term->fbase |
819 |
$terminal_rows = $term->nrow |
820 |
$terminal_columns = $term->ncol |
821 |
$has_focus = $term->focus |
822 |
$is_mapped = $term->mapped |
823 |
$max_scrollback = $term->saveLines |
824 |
$nrow_plus_saveLines = $term->total_rows |
825 |
$topmost_scrollback_row = $term->top_row |
826 |
Return various integers describing terminal characteristics. |
827 |
|
828 |
$x_display = $term->display_id |
829 |
Return the DISPLAY used by rxvt-unicode. |
830 |
|
831 |
$lc_ctype = $term->locale |
832 |
Returns the LC_CTYPE category string used by this rxvt-unicode. |
833 |
|
834 |
$env = $term->env |
835 |
Returns a copy of the environment in effect for the terminal as a |
836 |
hashref similar to "\%ENV". |
837 |
|
838 |
$modifiermask = $term->ModLevel3Mask |
839 |
$modifiermask = $term->ModMetaMask |
840 |
$modifiermask = $term->ModNumLockMask |
841 |
Return the modifier masks corresponding to the "ISO Level 3 Shift" |
842 |
(often AltGr), the meta key (often Alt) and the num lock key, if |
843 |
applicable. |
844 |
|
845 |
$screen = $term->current_screen |
846 |
Returns the currently displayed screen (0 primary, 1 secondary). |
847 |
|
848 |
$cursor_is_hidden = $term->hidden_cursor |
849 |
Returns wether the cursor is currently hidden or not. |
850 |
|
851 |
$view_start = $term->view_start ([$newvalue]) |
852 |
Returns the row number of the topmost displayed line. Maximum value |
853 |
is 0, which displays the normal terminal contents. Lower values |
854 |
scroll this many lines into the scrollback buffer. |
855 |
|
856 |
$term->want_refresh |
857 |
Requests a screen refresh. At the next opportunity, rxvt-unicode |
858 |
will compare the on-screen display with its stored representation. |
859 |
If they differ, it redraws the differences. |
860 |
|
861 |
Used after changing terminal contents to display them. |
862 |
|
863 |
$text = $term->ROW_t ($row_number[, $new_text[, $start_col]]) |
864 |
Returns the text of the entire row with number $row_number. Row 0 is |
865 |
the topmost terminal line, row "$term->$ncol-1" is the bottommost |
866 |
terminal line. The scrollback buffer starts at line -1 and extends |
867 |
to line "-$term->nsaved". Nothing will be returned if a nonexistent |
868 |
line is requested. |
869 |
|
870 |
If $new_text is specified, it will replace characters in the current |
871 |
line, starting at column $start_col (default 0), which is useful to |
872 |
replace only parts of a line. The font index in the rendition will |
873 |
automatically be updated. |
874 |
|
875 |
$text is in a special encoding: tabs and wide characters that use |
876 |
more than one cell when displayed are padded with $urxvt::NOCHAR |
877 |
characters. Characters with combining characters and other |
878 |
characters that do not fit into the normal tetx encoding will be |
879 |
replaced with characters in the private use area. |
880 |
|
881 |
You have to obey this encoding when changing text. The advantage is |
882 |
that "substr" and similar functions work on screen cells and not on |
883 |
characters. |
884 |
|
885 |
The methods "$term->special_encode" and "$term->special_decode" can |
886 |
be used to convert normal strings into this encoding and vice versa. |
887 |
|
888 |
$rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]]) |
889 |
Like "$term->ROW_t", but returns an arrayref with rendition bitsets. |
890 |
Rendition bitsets contain information about colour, font, font |
891 |
styles and similar information. See also "$term->ROW_t". |
892 |
|
893 |
When setting rendition, the font mask will be ignored. |
894 |
|
895 |
See the section on RENDITION, above. |
896 |
|
897 |
$length = $term->ROW_l ($row_number[, $new_length]) |
898 |
Returns the number of screen cells that are in use ("the line |
899 |
length"). Unlike the urxvt core, this returns "$term->ncol" if the |
900 |
line is joined with the following one. |
901 |
|
902 |
$bool = $term->is_longer ($row_number) |
903 |
Returns true if the row is part of a multiple-row logical "line" |
904 |
(i.e. joined with the following row), which means all characters are |
905 |
in use and it is continued on the next row (and possibly a |
906 |
continuation of the previous row(s)). |
907 |
|
908 |
$line = $term->line ($row_number) |
909 |
Create and return a new "urxvt::line" object that stores information |
910 |
about the logical line that row $row_number is part of. It supports |
911 |
the following methods: |
912 |
|
913 |
$text = $line->t ([$new_text]) |
914 |
Returns or replaces the full text of the line, similar to |
915 |
"ROW_t" |
916 |
|
917 |
$rend = $line->r ([$new_rend]) |
918 |
Returns or replaces the full rendition array of the line, |
919 |
similar to "ROW_r" |
920 |
|
921 |
$length = $line->l |
922 |
Returns the length of the line in cells, similar to "ROW_l". |
923 |
|
924 |
$rownum = $line->beg |
925 |
$rownum = $line->end |
926 |
Return the row number of the first/last row of the line, |
927 |
respectively. |
928 |
|
929 |
$offset = $line->offset_of ($row, $col) |
930 |
Returns the character offset of the given row|col pair within |
931 |
the logical line. Works for rows outside the line, too, and |
932 |
returns corresponding offsets outside the string. |
933 |
|
934 |
($row, $col) = $line->coord_of ($offset) |
935 |
Translates a string offset into terminal coordinates again. |
936 |
|
937 |
$text = $term->special_encode $string |
938 |
Converts a perl string into the special encoding used by |
939 |
rxvt-unicode, where one character corresponds to one screen cell. |
940 |
See "$term->ROW_t" for details. |
941 |
|
942 |
$string = $term->special_decode $text |
943 |
Converts rxvt-unicodes text reprsentation into a perl string. See |
944 |
"$term->ROW_t" for details. |
945 |
|
946 |
$success = $term->grab_button ($button, $modifiermask) |
947 |
Registers a synchronous button grab. See the XGrabButton manpage. |
948 |
|
949 |
$success = $term->grab ($eventtime[, $sync]) |
950 |
Calls XGrabPointer and XGrabKeyboard in asynchronous (default) or |
951 |
synchronous ($sync is true). Also remembers the grab timestampe. |
952 |

$term->allow_events_async |
954 |
Calls XAllowEvents with AsyncBoth for the most recent grab. |
955 |
|
956 |
$term->allow_events_sync |
957 |
Calls XAllowEvents with SyncBoth for the most recent grab. |
958 |
|
959 |
$term->allow_events_replay |
960 |
Calls XAllowEvents with both ReplayPointer and ReplayKeyboard for |
961 |
the most recent grab. |
962 |
|
963 |
$term->ungrab |
964 |
Calls XUngrab for the most recent grab. Is called automatically on |
965 |
evaluation errors, as it is better to lose the grab in the error |
966 |
case as the session. |
967 |
|
968 |
$atom = $term->XInternAtom ($atom_name[, $only_if_exists]) |
969 |
$atom_name = $term->XGetAtomName ($atom) |
970 |
@atoms = $term->XListProperties ($window) |
971 |
($type,$format,$octets) = $term->XGetWindowProperty ($window, $property) |
972 |
$term->XChangeWindowProperty ($window, $property, $type, $format, |
973 |
$octets) |
974 |
$term->XDeleteProperty ($window, $property) |
975 |
$window = $term->DefaultRootWindow |
976 |
$term->XReparentWindow ($window, $parent, [$x, $y]) |
977 |

980 |
($x, $y, $child_window) = $term->XTranslateCoordinates ($src, $dst, $x, |
981 |
$y) |
982 |
$term->XChangeInput ($window, $add_events[, $del_events]) |
983 |
Various X or X-related functions. The $term object only serves as |
984 |
the source of the display, otherwise those functions map |
985 |
more-or-less directory onto the X functions of the same name. |
986 |
|
987 |
The "urxvt::popup" Class |
988 |
$popup->add_title ($title) |
989 |

The "urxvt::timer" Class |
1008 |
This class implements timer watchers/events. Time is represented as a |
1009 |
fractional number of seconds since the epoch. Example: |

|
1011 |
$term->{overlay} = $term->overlay (-1, 0, 8, 1, urxvt::OVERLAY_RSTYLE, 0); |
1012 |
$term->{timer} = urxvt::timer |
1013 |
->new |
1014 |
->interval (1) |
1015 |
->cb (sub { |
1016 |
$term->{overlay}->set (0, 0, |
1017 |
sprintf "%2d:%02d:%02d", (localtime urxvt::NOW)[2,1,0]); |
1018 |
}); |
1019 |
|
1020 |
$timer = new urxvt::timer |
1021 |

1022 |
immediately. |
1023 |
|
1024 |
$timer = $timer->cb (sub { my ($timer) = @_; ... }) |
1025 |
Set the callback to be called when the timer triggers. |
1026 |
|
1027 |
$tstamp = $timer->at |

1032 |
|
1033 |
$timer = $timer->interval ($interval) |
1034 |
Normally (and when $interval is 0), the timer will automatically |
1035 |
stop after it has fired once. If $interval is non-zero, then the |
1036 |
timer is automatically rescheduled at the given intervals. |
1037 |
|
1038 |
$timer = $timer->start |
1039 |
Start the timer. |
1040 |
|
1041 |
$timer = $timer->start ($tstamp) |
1042 |
Set the event trigger time to $tstamp and start the timer. |
1043 |
|
1044 |
$timer = $timer->after ($delay) |
1045 |
Like "start", but sets the expiry timer to c<urxvt::NOW + $delay>. |
1046 |
|
1047 |
$timer = $timer->stop |
1048 |
Stop the timer. |
1049 |
|
1050 |

1055 |
->new |
1056 |
->fd (fileno $term->{socket}) |
1057 |
->events (urxvt::EVENT_READ) |
1058 |
->start |
1059 |
->cb (sub { |
1060 |
my ($iow, $revents) = @_; |
1061 |
# $revents must be 1 here, no need to check |
1062 |
sysread $term->{socket}, my $buf, 8192 |
1063 |
or end-of-file; |
1064 |
}); |
1065 |

1078 |
"urxvt::EVENT_READ" and "urxvt::EVENT_WRITE", which might be ORed |
1079 |
together, or "urxvt::EVENT_NONE". |
1080 |

1082 |
Start watching for requested events on the given handle. |
1083 |
|
1084 |
$iow = $iow->stop |
1085 |
Stop watching for events on the given filehandle. |
1086 |
|
1087 |
The "urxvt::iw" Class |
1088 |
This class implements idle watchers, that get called automatically when |
1089 |
the process is idle. They should return as fast as possible, after doing |
1090 |
some useful work. |
1091 |
|
1092 |

This class implements process watchers. They create an event whenever a |
1106 |
process exits, after which they stop automatically. |
1107 |
|
1108 |
my $pid = fork; |
1109 |
... |
1110 |
$term->{pw} = urxvt::pw |
1111 |
->new |
1112 |
->start ($pid) |
