Concmath-otf package
====================
## Description
`Concrete-Math.otf’ is an Opentype version of the Concrete Math font
created by Ulrik Vieth in MetaFont. `concmath-otf.sty’ is a replacement
for the original `concmath.sty’ package.
## Contents
* Concrete-Math.otf OpenType Math font
* concmath-otf.sty LaTeX style file: replaces concmath.sty for LuaTeX/XeTeX
* concmath-otf.pdf Documentation in PDF format
* concmath-otf.ltx LaTeX source of concmath-otf.pdf
* unimath-concrete.pdf Modified version of unimath-symbols.pdf
showing available Concrete-Math symbols compared to
LatinModern, STIXTwo, TeXGyrePagella and DejaVu.
* unimath-concmath.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.
Concrete-Math.otf in directory texmf-local/fonts/opentype/public/concmath-otf/
and concmath-otf.sty in directory texmf-local/tex/latex/concmath-otf/.
Documentation files and their sources can go to directory
texmf-local/doc/fonts/public/concmath-otf/
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 Concrete-Math font
(fontconfig under Linux).
## License
* The font `Concrete-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
* v. 0.21
- Integrals are now slanted by default, option "Style=upint" (+ss03)
make them upright.
- More integrals added: U+222F to U+2233 and U+2A11.
- Corrected symbols prime, dprime, etc. (U+2032 to U+2037).
* v. 0.22
- concmath-otf.sty loads Concrete-Math.otf by file name for XeTeX.
- Glyphs corrections: \sum, \prod, \coprod and \amalg, \infty,
\propto, \wp, \ell redesigned;
* v. 0.23
- Delimiters, integrals, sum, prod etc. are now vertically
centred by design on the maths axis (required by luametatex).
- Upright integrals: fixed left bearings.
* v. 0.24
- Fixed \wideoverbar (U+0305) which failed with XeTeX.
- Corrected negative right bearings of some display integrals.
- Added stretchable integral for U+222B (usable with luametatex).
* v. 0.25
- Package now compatible with mathtools’ stretchable arrows.
- Corrected some glyphs’ inconsistencies (maths axis, etc.).
- \diagup and \diagdown moved from private area to U+27CB, U+27CD.
* v. 0.40
- Added missing stretchable glyhs: \wideoverbar, \widecheck, \widebreve,
\overrightharpoon, \overleftharpoon, \overleftrightharpoon,
\underrightharpoon, \underleftharpoon, \underleftrightharpoon,
\underrightarrow, \underleftarrow, \underleftrightarrow,
\mathunderbar, \underbracket, \wideutilde.
- \overbrace, \underbrace redrawn (all sizes).
- Metrics corrected: \overparen, \overrightarrow, \overleftarrow,
\overleftrightarrow.
- Many glyphs have been emboldened (suggested by Mikael Sundqvist and
Hans Hagen).
- Most horizontal arrows and harpoons are now stretchable (dito).
- Glyphs \leqqslant, \geqqslant, \nleqqslant, \ngeqqslant added.
* v0.41:
- radicals corrected.
- concmath-otf.sty: options handled by `l3keys` instead of `xkeyval`
(requires a LaTeX kernel not older than 2022-06-01).
* v0.50:
- Digits and Lowercase Blackboard Bold glyphs added (adapted from
Erewhon-Math).
- Many math symbols added, the coverage now compares to the TeXGyre fonts.
- Sans-serif alphabets (Latin and Greek) added, they are derived from
Iwona text fonts.
- Typewriter alphabet (Latin) added, derived from RobotoMono-Regular.
- Bold Script (Uppercase only) glyphs added.
* v0.61:
- Fixed IsExtendedShape flags.
- \mid (U+2223) and \parallel (U+2225) vertical variants changed.
- Blackboard bold capitals redesigned from scratch to match Concrete
upright capitals.
- Bold glyphs redesigned.
- Concrete-Math-Bold.otf added (minimal subset of glyphs).
- Superscripts get a suitable boldness (ssty feature enhanced).
- Inconsistencies between delimiter sizes fixed.
- Metrics of \widebreve, \widecheck, \widehat, \widetilde first
horizontal variant (.h0) changed: f.i. $\hat{r} \ne \widehat{r}$.
