Although not strictly needed, we also provide a family name mapping -%D mechanism as used in the (original) AMS math definition files, but here these -%D names can recursively be remapped and if needed, dynamically be changed. We've -%D tried to minimize the number of definition commands and use plain \TEX\ -%D definitions as fallback. We've tried to follow a couple of conventions from plain -%D and AMS math in order to achieve backward compatinility. We also kept an eye on -%D future usage of these modules in the perspective of MathML and unicode fonts. In -%D the meantime much has been dropped in favour of better alternatives. - -%D There is a subtle issue with grouping: the \type {\begingroup} method will not -%D restore a changed mathstyle so best avoid that one. However, there are cases where -%D we really need to use such grouping. We now have \type {\beginmathgroup} etc. +%D This is the \LMTX\ version of math support what evolved over decades. We started +%D out with native display math, battled for years with the heuristic spacing, +%D assumptions wrt number locations etc. Advanced alignments were implemented with +%D the help of Aditya. In \MKIV\ everything got upgraded, and we ended up with three +%D models for spacing and numbering: traditional (display), improved (using some +%D \LUATEX\ control options), and future (using emulated display) where we also +%D could handle multi|-|line formulas well. As \LUAMETATEX\ evolved it became clear +%D that we should drop the first two models completely and stick to the emulated +%D display mode combined with the ability to format multi|-|line formulas in greater +%D detail. +%D +%D One can wonder what this does with compatibility. Of course we try to be +%D interface compatible but better micro typography spacing has consequences. +%D However, in practice it looks like we get better results without too many side +%D effects. Also, we're not bound to for instance \AMS\ math because \CONTEXT\ is +%D not used by scientific publishers. In fact over the 15 plus years of development +%D (2022), no professional publisher (or large scale \TEX\ user) ever expressed +%D interest in \LUATEX\ and \LUAMETATEX, definitely not in relation to math, which +%D made it even more easy to upgrade the engine as well as \CONTEXT\ math and over +%D time users have demonstrated to appreciate improvements. We can do as we like, as +%D long as users like it too. It's with that mindset that Mikael Sundqvist and I +%D undertook this effort which took a year to mature. It started out with +%D implementing advanced spacing models based on inter|-|atom properties and control +%D but stepwise more got added and improved. We also settled on the fact that fonts +%D will never be perfect and that we need runtime fixing. That took some work but in +%D the end put less burden on the engine. +%D +%D After an extremely short discussion MS and HH decided that we will not support +%D \quote {BS ISO 80000-2:2009} because it doesn't comply to the CMS quality +%D standards and is BS anyway. %D Musical timestamp for the April 2022 math (inline) snapping sub activity: eNerd⁴ %D Time Capsule 2020 a.k.a.
