[NTG-context] bugs in math engine?
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
---

I don't know whether the font or luatex/context is at fault.
3. The command \implies is undefined (see previous posting).
Hans, can we add this somewhere?

If someone can give me a strategy (pseudo code welcome) which alpha/beta/stable to put into the repository this should be quite easy to do. How about two branches: one for all officical stable releases, and one for all beta releases (from Hans's ftp server, synced periodically). I believe that alpha releases are rare enough to be ignored[1]. Unless disk space is a problem, I do not see a reason for not storing all betas. Official betas can be tagged with the release date and time.

Official betas can be tagged with the release date and time. OK, thats what I had in mind. Perhaps Mojca can tell me where all the files are on the server, if not I will find out by myself. I promise I will give it a try next week sunday, until then I don't have internet access (vacation :) and my battery from my notebook is almost empty because I've forgot my power supply at home :-) Patrick -- ConTeXt wiki and more: http://contextgarden.net ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

where to look ...

Yes, I should unlearn amsmath syntax at some stage.

%unexpanded\def\mathsf #1{{}
