351
352=item $urxvt::LIBDIR
353
354The rxvt-unicode library directory, where, among other things, the perl
355modules and scripts are stored.
356
357=item $urxvt::RESCLASS, $urxvt::RESCLASS
358
359The resource class and name rxvt-unicode uses to look up X resources.
360
361=item $urxvt::RXVTNAME
362
363The basename of the installed binaries, usually C<urxvt>.
364
365=item $urxvt::TERM
366
367The current terminal. This variable stores the current C<urxvt::term>
368object, whenever a callback/hook is executing.

374=head2 Functions in the C<urxvt> Package
375
376=over 4
377
378=item $term = new urxvt [arg...]
379
380Creates a new terminal, very similar as if you had started it with
381C<system $binfile, arg...>. Croaks (and probably outputs an error message)
382if the new instance couldn't be created. Returns C<undef> if the new
383instance didn't initialise perl, and the terminal object otherwise. The
384C<init> and C<start> hooks will be called during the call.
385
386=item urxvt::fatal $errormessage
387
388Fatally aborts execution with the given error message. Avoid at all
389costs! The only time this is acceptable is when the terminal process
390starts up.
391
392=item urxvt::warn $string
393
394Calls C<rxvt_warn> with the given string which should not include a
395newline. The module also overwrites the C<warn> builtin with a function
396that calls this function.
397
398Using this function has the advantage that its output ends up in the
399correct place, e.g. on stderr of the connecting urxvtc client.
400
401=item $is_safe = urxvt::safe
402
403Returns true when it is safe to do potentially unsafe things, such as
404evaluating perl code specified by the user. This is true when urxvt was
405started setuid or setgid.
406
407=item $time = urxvt::NOW
408
409Returns the "current time" (as per the event loop).

414Mod3Mask, Mod4Mask, Mod5Mask, Button1Mask, Button2Mask, Button3Mask,

416
417Various constants for use in X calls and event processing.
418
419=back
420
421=head2 RENDITION
422
423Rendition bitsets contain information about colour, font, font styles and
424similar information for each screen cell.
425
426The following "macros" deal with changes in rendition sets. You should
427never just create a bitset, you should always modify an existing one,
428as they contain important information required for correct operation of
429rxvt-unicode.
430
431=over 4
432
433=item $rend = urxvt::DEFAULT_RSTYLE
434
435Returns the default rendition, as used when the terminal is starting up or
436being reset. Useful as a base to start when creating renditions.
437
438=item $rend = urxvt::OVERLAY_RSTYLE
439
440Return the rendition mask used for overlays by default.
441
442=item $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
443
444Return the bit that enabled bold, italic, blink, reverse-video and
445underline, respectively. To enable such a style, just logically OR it into
446the bitset.
447
448=item $foreground = urxvt::GET_BASEFG $rend
449
450=item $background = urxvt::GET_BASEBG $rend
451
452Return the foreground/background colour index, respectively.
453
454=item $rend = urxvt::SET_FGCOLOR $rend, $new_colour
455
456=item $rend = urxvt::SET_BGCOLOR $rend, $new_colour
457
458Replace the foreground/background colour in the rendition mask with the
459specified one.
460
461=item $value = urxvt::GET_CUSTOM $rend
462
463Return the "custom" value: Every rendition has 5 bits for use by
464extensions. They can be set and changed as you like and are initially
465zero.
466
467=item $rend = urxvt::SET_CUSTOM $rend, $new_value
468
469Change the custom value.

788Croaks (and probably outputs an error message) if the new instance
