Euler-Math package ==================== ## Description 'Euler-Math.otf' (formerly named 'Neo-Euler.otf') is an OpenType version of Hermann Zapf’s Euler maths font. It is the continuation of the Euler project initiated by Khaled Hosny in 2009 and abandoned in 2016. A style file 'euler-math.sty' is provided as a replacement of the 'eulervm.sty' package for LuaLaTeX and XeLaTeX users. ## Contents * Euler-Math.otf OpenType maths font * euler-math.sty LaTeX style file: replaces eulervm.sty for LuaTeX/XeTeX * neo-euler.sty For compatibility with the former name * Euler-Math.pdf Documentation in PDF format * Euler-Math.ltx LaTeX source of Euler-Math.pdf * unimath-euler.pdf Modified version of unimath-symbols.pdf showing available Euler-Math symbols compared to LatinModern, STIXTwo, Erewhon, TeXGyrePagella and Asana. * unimath-euler.ltx LaTeX source of unimath-concrete.pdf * README.md (this file) ## Installation This package is meant to be installed automatically by TeXLive, MikTeX, etc. Otherwise, the package can be installed under TEXMFHOME or TEXMFLOCAL, f.i. Euler-Math.otf in directory texmf-local/fonts/opentype/public/euler-math/ and euler-math.sty in directory texmf-local/tex/latex/euler-math/. Documentation files and their sources can go to directory texmf-local/doc/fonts/public/euler-math/ Don't forget to rebuild the file database (mktexlsr or so) if you install under TEXMFLOCAL. Finally, make the system font database aware of the Euler-Math font (fontconfig under Linux). ## License * The font 'Euler-Math.otf' is licensed under the SIL Open Font License, Version 1.1. This license is available with a FAQ at: http://scripts.sil.org/OFL * The other files are distributed under the terms of the LaTeX Project Public License from CTAN archives in directory macros/latex/base/lppl.txt. Either version 1.3 or, at your option, any later version. ## Changes * First public version: 0.20 * v0.21: - Delimiters, integrals, sum, prod etc. are now vertically centred by design on the maths axis (required by luametatex). * v0.22: - Sizes of vertical variants of \lAngle, \rAngle, \langle and \rangle corrected. - Added stretchable integral for U+222B (usable with luametatex). * v0.30: - *Name of the package changed from Neo-Euler to Euler-Math*; the former 'neo-euler.sty' style file has been kept for compatibility, it now loads 'euler-math.sty' and warns about the change. * v0.31: - Package now compatible with mathtools’ stretchable arrows. - \diagup and \diagdown moved from private area to U+27CB, U+27CD. * v0.40: - Metrics of all "over" arrows and harpoons corrected. - Metrics of all "under" arrows and harpoons corrected. - Most horizontal arrows and harpoons are now stretchable. * v0.41: - radicals corrected. - euler-math.sty: options handled by `l3keys` instead of `xkeyval` (requires a LaTeX kernel not older than 2022-06-01). * v0.50: - Italic and BoldItalic alphabets filled with their upright counterparts as suggested by Ulrik Vieth. - Sans-serif alphabets (Latin and Greek) added, they are derived from IBMPlexSans text fonts. - Typewriter alphabet (Latin) added, derived from UMTypewriter-Regular. * v0.51: - Fixed IsExtendedShape flags. - \mid (U+2223) and \parallel (U+2225) vertical variants changed. - OT features cvNN are now applied before ssty (applied last). --- Copyright 2009-2016 Khaled Hosny Copyright 2022-2023 Daniel Flipo E-mail: daniel (dot) flipo (at) free (dot) fr
