Dear list,
the following are probably bugs in the new math engine as of
yesterday's beta (2009.05.14 16:44):
1. The symbols for number sets in Cambria Math aren't taken from the
double-struck variant.
---
\usetypescript[cambria]
\setupbodyfont[cambria]
\starttext
\math{\naturalnumbers}, \math{\integers}, \math{\rationals},
\math{\reals}, \math{\complexes}, \math{\primes}
\stoptext
---
2. Vector arrows look somewhat strange in Cambria Math ... is this
perhaps due to the font itself?
---
\usetypescript[cambria]
\setupbodyfont[cambria]
\starttext
The arrows should neither extend over the right bracket nor into the
primes:
\startformula{}
[\alpha(\vec{k})\alpha(\vec{k}'),\alpha^\dagger(\vec{k}'')]
\stopformula
\stoptext
---
3. The command \implies is undefined (see previous posting).
---
\starttext
\startformula
A\implies B
\stopformula
\stoptext
---
Oliver

Hans, please apply the following patch to math-def.mkiv

I don't know whether the font or luatex/context is at fault.

Hans, can we add this somewhere?
%D This is a temporary hack until we figure out how to do this correctly.
\unexpanded\def\implies {\mathrel{\;\Longrightarrow\;}}

Many thanks! Although this doesn't quite solve the bug yet, now I know
where to look ...
Test case:
---
\starttext
\math{\primes P},
\math{\naturalnumbers N},
\math{\integers Z},
\math{\rationals Q},
\math{\reals R},
\math{\complexes C}
\stoptext
---
Proposed patch:
diff math-def.mkiv.orig math-def.mkiv
100,105c100,105
< \definemathcommand [integers] {\mathblackboard{Z}}
< \definemathcommand [reals] {\mathblackboard{R}}
< \definemathcommand [rationals] {\mathblackboard{Q}}
< \definemathcommand [naturalnumbers]{\mathblackboard{N}}
< \definemathcommand [complexes] {\mathblackboard{C}}
< \definemathcommand [primes] {\mathblackboard{P}}

Hans, Aditya, does this make sense?

Yes, I should unlearn amsmath syntax at some stage.

\unexpanded\def\mathscript {\setmathalphabet{script}}
\unexpanded\def\mathfraktur {\setmathalphabet{fraktur}}
\unexpanded\def\mathblackboard{\setmathalphabet{blackboard}}
we can make these into
\unexpanded\def\mathscript #1{{\setmathalphabet{script}#1}}
\unexpanded\def\mathfraktur #1{{\setmathalphabet{fraktur}#1}}
\unexpanded\def\mathblackboard#1{{\setmathalphabet{blackboard}#1}}
\unexpanded\def\mathsr{\setmathalphabet{script}}
\unexpanded\def\mathfr{\setmathalphabet{fraktur}}
\unexpanded\def\mathbb{\setmathalphabet{blackboard}}
does that make sense?

Actually, better will be if we go for full ams compatibility:
Leave \mathscript, \mathfraktur, and \mathblackboard as they are, and
define
\unexpanded\def\mathcal #1{{\setmathalphabet{script}#1}}
\unexpanded\def\mathfrak#1{{\setmathalphabet{fraktur}#1}}
\unexpanded\def\mathbb #1{{\setmathalphabet{blackboard}#1}}
%TODO: Once bold is settled
%unexpanded\def\mathbf #1{{\setmathalphabet{bold}#1}}
% TODO: I need to actually see what exactly these commands to
%unexpanded\def\mathrm #1{{....}
%unexpanded\def\mathit #1{{....}
% TODO: Probably better will be \mathss since we use ss for sans serif
%unexpanded\def\mathsf #1{{....}
% TODO: \mathscr is euler script. We can add this, but need to figure out
% how to deal with two script families in a configurable way
% For LM one can go with either euler script or RSFS (or both?)
%unexpanded\def\mathscr #1{{...}
