CTAN update: setbuilder
by CTAN Announcements via ctan-ann 30 Jul '26

30 Jul '26

Vseslav Sekorin submitted an update to the setbuilder package. Version: 0.2.0 License: mit Summary description: Mathematical sets with correctly scaled braces and separator Announcement text: -------------------------------------------------------------------------------- setbuilder 0.2 Following a recommendation in the TeXbook, a thin space is now set inside the braces of set-builder notation. It is added only where the body contains a separator, so enumerations such as \set{1,2,3} are left as they were. The amount is set with the new pad key, and pad=none restores the previous appearance. This changes the appearance of existing documents that use \set together with \given or \suchthat. Thanks to Murray Eisenberg for this suggestion. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/setbuilder More information is at https://ctan.org/pkg/setbuilder -------------------------------------------------------------------------------- Thanks for the upload.

Version: 1.0 2026-07-26 License: lppl1.3c Summary description: Use Unicode combining accents in math input with LuaLaTeX Announcement text: ------------------------------------------------------------------------ luamathaccents lets you type accented mathematical symbols directly in your source file using Unicode combining characters. With the package loaded, the two-character sequence “x” + U+0302 (combining circumflex accent) – which your editor displays as an accented letter – is rewritten on input to “\hat x”, and likewise for two dozen other combining characters (grave, acute, tilde, macron, breve, dot, diaeresis, caron, vector arrow, harpoons, and more). The package uses LuaTeX’s process_input_buffer callback and therefore requires LuaLaTeX.
