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.
    • Blackboard Bold glyphs added (derived from Michel Bovani's Fourier).
• 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).
• v0.60:
  • Vertical variants of parentheses and braces redesigned to better match the shapes of the base glyphs.
    • Inconsistencies between vertical delimiter sizes fixed.
    • All sub/sup-scripts redesigned (they were far too wide).
• v0.61:
  • Fixed Game glyph (U+2141).
• v0.62:
  • Fixed superscripts for infty (U+221E).
    • Added glyph degree (U+00B0).
    • hbar now differs from hslash.
    • bar (U+0304), wideoverbar (U+0305), mathunderbar (U+0332) thicknesses'
    unified to default rule thickness.
    • Glyphs U+2032 to U+2037 and U+2057 (prime and co.) resized so that f.i.
    (f'), (fprime) and (f^{prime}) produce the same output.
• v0.63:
  • Math table fixes for horizontal composition of over/underbrace.
• v0.70:
  • Greek msans and mitsans glyphs added in Private Area.
  • Invisible Math operators (U-2061 to U+2064) added.
  • Compatibility with Typst v0.14: all glyphs used in vertical compositions now sit on the baseline.
  • Documentation fixes.
