math and palatino

math and palatino

[Idris Samawi Hamid ادريس سماوي حامد]

Dear gang,
[mkiv only]

What is the best available math font for use with Pagella/Palatino? [Hint:  
it's not LM] I had to roll my own typescript so what I need to fill in is  
the commented line below

\definetypeface [pagella_ar] [rm] [serif] [pagella_arabic] %  
[pagella_arabic]
% \definetypeface [pagella_ar] [mm] [math]  [palatino]       [default]

Uncommenting the above gives me an incomplete math font that does not look  
good. Any ideas on getting this right? Is there an otf euler option?

Best wishes
Idris

The math fonts compatible with Palatino are px math and math paza ConTeXt 
only has support for px math.

Currently, no math font in mkiv is "complete". Which specific glyphs are 
missing for you?

The easiest opiton is to use asana math, which is an otf math font based 
on px fonts.

\starttypescript [math] [asana] [name]
     \definefontsynonym [MathRoman] [name:Asana-Math] [features=math\mathsizesuffix]
\stoptypescript

and then

\definetypeface [pagella_ar] [mm] [math]  [asana]       [default]

> that does not look good. Any ideas on getting this right?

I also find px math ugly (although I did use it for my thesis). math pazo 
is not much better, it uses most of the symbols from cm. There is a 
commerical math from micropress that is supposed to be compatible with 
palatino, but I have never used it myself.

> Is there an otf euler option?

No. Also keep in mind that euler is no where close to being a complete 
math font. Mkii used a virtual font that took missing symbols from px 
math and cm.

I have a local half baked support for Euler, which uses missing symbols 
from iwona. I can send the patch if you want to experiment with it.

I would love that as well. Is it on the wiki?

Keep in mind that this is/was an experiment. I am still trying to 
understand how to create virtual fonts on the fly. In order to use this, 
you need

\starttypescript [math][euler][all]
     \definefontsynonym[MathRoman][euler@euler-math]
     \loadmapfile[original-ams-euler.map]
     \loadmapfile[iwona-ex.map]
     \loadmapfile[iwona-sy.map]
\stoptypescript

then

\definetypescript[whatever][mm][euler][default][text=rm]

LuaTeX warning (file  
C:/ConTeXt/tex/texmf-project/fonts/data/asana/Asana-Math.otf): Type2  
Charstring Parser: Unknown charstring operator: 0x00

!LuaTeX error (file

Have any of you run into this before?

If this is a showstopper, then a fallback will have to do. Have any of you  
made fallbacks for math fonts? Are there any subtleties compared to  
regular fonts? What is the unicode slot for math \alpha?

Thanks! time is very short, although I like Euler and think it would work  
for palatino... maybe we need to get the gyre people on it for the  
future:-)

Turns out that cambria is preset in mkiv and works, so I'll use that for  
now. I filed a report about the asana error so hopefully that will be  
solved as well.

[I use math so little I had completely forgotten about cambria].

Thanks, Aditya!

No. I am using the minimals from 2009.05.26, and asana math works fine. 
Are you using the latest version of the font from 
http://openfontlibrary.org/media/files/asyropoulos/219

Basic greek should work in math. I cannot get the latest minimals right 
now (slow internet connection), but px math and lm math use the same code 
to generate virtual fonts, so px math should work in the latest minimals.

seems the same date as

http://www.ctan.org/get/fonts/Asana-Math/Asana-Math.otf

+

This is LuaTeX, Version beta-0.41.0-2009061016

I reported this to Taco so we'll see what he says...

Using the predefined

[mm] [math] [palatino]

You can test these formulas in px-math:

\starttext
\startformula
Y=AK^{\alpha{}}L^{1-\alpha{}} \eqno(1)
\stopformula

\startformula
y-l=a+\alpha(k-l) \eqno(2)
\stopformula

\startformula
a = (y-l) - \alpha{} (k-l) \eqno(3)
\stopformula

\startformula
A = (3-7)-(0.3) (5-3) = 3.4
\stopformula

\alpha{}
\stoptext

I see. There is indeed something wrong with both px-math and tx-math, but 
I cannot see why it is behaving differently. In math-vfu.lua, if you 
replace pxmi.tfm with lmmi10.tfm and regenerate formats, greek in math 
works, so it is something specific with the font.

Hans, Taco: Any idea what is happening here? Minimal test file

\usetypescript[palatino] \setupbodyfont[palatino]
\starttext $\alpha \beta$ \stoptext

Idris: For greek outside the math mode, you should use \greekalpha etc, 
which works with palatino.

That version of Asana works for me with a small test file, using

  This is LuaTeX, Version beta-0.41.0-2009061815 (Web2C 2009)

but it could be a problem with a specific glyph, so can you send a
minimal test file?
