Italic correction missing when using \left...\right
by Henri Menke 26 Apr '22

26 Apr '22

Dear devs, When using delimiter with \left...\right the italic correction between the preceding letter and the delimiter is dropped. I've tried this with a few fonts and all show the problem. For Libertinus Math the glyphs even overlap. MWE for mtxrun --script plain (TeX Live 2022) %\input luaotfload.sty \font\mathfont="file:LibertinusMath-Regular.otf:mode=base;script=math" at 10pt \textfont0=\mathfont \textfont2=\mathfont \Umathcodenum`f="1D453 \protected\def\langle{\Udelimiter"4"0"27E8\relax} \protected\def\rangle{\Udelimiter"5"0"27E9\relax} $f\rangle$ \nulldelimiterspace=0pt $\left.f\right\rangle$ \bye Cheers, Henri

Where is the LuaTeX SVN?
by Henri Menke 18 Apr '22

18 Apr '22

Dear list, On the ConTeXt wiki there are links to the LuaTeX SVN: https://wiki.contextgarden.net/ConTeXt_Standalone/Implementation#LuaTeX SVN: https://foundry.supelec.fr/svn/luatex ViewVC: https://foundry.supelec.fr/scm/viewvc.php/?root=luatex Files: http://foundry.supelec.fr/gf/project/luatex/frs/ However, none of these links work. All connections time out. Somewhere on the mailing list I found this alternative server https://serveur-svn.lri.fr/svn/modhel/luatex/ but this doesn't have ViewVC to browse the history. Cheers, Henri
