openSUSE Recommended Update: Recommended update for rxvt-unicode ______________________________________________________________________________ Announcement ID: openSUSE-RU-2022:10227-1 Rating: moderate References: Affected Products: openSUSE Backports SLE-15-SP4 ______________________________________________________________________________ An update that has 0 recommended fixes can now be installed. Description: This update for rxvt-unicode fixes the following issues: Update to version 9.30: * the background extension did not initialise properly when automatically loaded via the OSC. * new "on_attach" hook type implemented, to initialise late-loading extensions. Update to version 9.29: * libptytty (http://dist.schmorp.de/libptytty/) is now a required external dependency. * enable confirm-paste extension by default, can be disabled by e.g. URxvt.perl-ext: -confirm-paste * Key bindings specified with the -keysym option or with resources of the form URxvt*keysym work again. Such resources, as opposed to * resources of the form URxvt.keysym, were not officially allowed but accepted, so ignoring them is considered a regression. * new option/resource -rm/rewrapMode, which sets the line rewrap mode to auto, never or always. * new option/resource -dpb/disablePasteBrackets, which can be used to disable bracketed paste mode sequences, as more and more programs * abuse these sequences (typically in the name of security, but these sequences are not improving security). Also, bracketed paste mode is now under frills. * add manpage for urclock. * confirm-paste wrongly considered brackets as ctrlchars (patch by Jakub Wilk, debian bug #995244). * if urxvt cannot detect a good estimate for font width (because a font does not contain latin characters at all for example), it will now fall back to xft's max_advance_width, which works well with some fonts. It currently will warn about this. * do not render variation selectors in the default font as boxes, treat them as zero-width characters. * change combining character architecture to allow fonts to handle combining sequences on their own. This could allow future renderers to be more intelligent about these sequences. * use the previous enhancement to allow unicode characters outside of the BMP to be rendered even without --enable-unicode3, as long as an xft with the character is configured. * It's recommended to stay with disabled unicode3 even more now. * freetype/xft have been verified to return nonsensical offsets for combining characters. urxvt tries to compensate to some extent, but diacritics will be slightly off in many cases, and far off in some cases (e.g. input mono). * when checking for overlap/careful handling, take non-basefont character shifts into account. * extensions can now request autoloading on OSC and Perl OSC sequences, implement this for the background, clipboard-osc and overlay-osc extensions. * the background extension will now be autoloaded when the OSC 20 or 705 sequence is received. * added OSC 776 sequence to return character cell width, height and font ascent, which is useful when using urxvt as slave to calculate window size form or to row/column count. * matcher extension documentation now points out some requirements for regular expressions. the default url matching regex will now try to match IRLs in addition to URLs. * The view_start perl method now scrolls to the bottom also when the argument is greater than 0. * eval scroll actions now scroll to the bottom when scrolling down and there are less lines to scroll than the ones requested (reported by Stephen Talley). * allow perl-ext and perl-ext-common to override autoloaded extensions. this allows tabbed to disable itself in subtabs, avoiding recursive loading. * update precompose table to unicode 13.0. * update charset conversion tables to perl 5.32 (this only affected cs_koi8_u_from_unicode). * unicode characters > 0x100000 were not handled correctly w.r.t. font rendering. * replace bitstream vera by dejavu sans, as it has replaced the former almost everywhere. * urxvt will now try tic -x first and only fall back to tic without -x when tic -x fails. * fix urclock not erasing the old date on the clock face, causing overdraw, plus a host of other small fixes and improvements. * shave off over 1K of code size from urclock by replacing the sine table with a slightly less accurate fixed point approximation. * do not specify indentation with =over in pod, this is no longer needed with semi-modern pod tools and gives the formatter more stylistic freedom. * background extension did not set the "size-sensitive" flag when repeat mode wasn't normal. * extensions are now subjected to "use strict 'subs'". * avoid crashing when xft successfully opens a font but then somehow can't lock the face. * locale_decode/encode api methods now pass through undef unchanged. * fix undefined behaviour in the perl hook function, as diagnosed by clang.
