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).

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).
