Persian digits in math formulas

Persian digits in math formulas

[Mingranina Gingranina]

Dear All,
 Hello,

 I am trying to use Persian digits in math formulas. My document reads:

\font\4 = {name:dejavusans} at 10pt

\font\5 = {name:dejavusans} at 7pt

\font\6 = {name:dejavusans} at 5pt

\textfont4=\4 \scriptfont4=\5 \scriptscriptfont4=\6

\Umathcode`3="1"4`۳

\definefontfeature [persian] [arabic]

\mainlanguage[pe]

\starttext

  \definedfont[dejavusans*persian]

  \setupalign[r2l]

    این یک آزمایش است.

  3+2=5

  $3+2=5$

    \setupalign[l2r]

    This is a test.

  3+2=5

  $3+2=5$

\stoptext

 However in the output the replaced digit "3" disappears.
 Any help is gratefully appreciated.

 Thanks,
 Mingranina

For a text font you can add:

\definefontfeature [persian-fake-math] [arabic] [anum=yes]

and say:

     \definedfont[dejavusans*persian-fake-math]

but ... nicer is this:

\mainlanguage[pe]

\usetypescriptfile[dejavu]

\definetypeface [dejavu] [rm] [serif] [dejavu]   [default]
\definetypeface [dejavu] [ss] [sans]  [dejavu]   [default]
\definetypeface [dejavu] [tt] [mono]  [dejavu]   [default]
\definetypeface [dejavu] [mm] [math]  [xitsbidi] [default] 
[direction=both,rscale=1.2]

\setuptypeface[dejavu]

\starttext

     \start \setupalign[r2l] \setupmathematics[align=r2l] arabic: این یک 
آزمایش است. \par text: 3+2=5 \par math: $3+2=5$ $\sqrt{3+2=5}$ \par \stop

     \start \setupalign[l2r] \setupmathematics[align=l2r] latin:  This 
is a test.    \par text: 3+2=5 \par math: $3+2=5$ $\sqrt{3+2=5}$\par \stop

\stoptext

(see bidi-001.tex in the test suite)

 Dear Hans,
 Hello

 Thank you very much for your reply.
 A math formula In Persian language is exactly the same as in English
language except that the
 digits should be written in Persian. So what I want to do is to
replace the English digits with
 Persian digits in a math formula. However, with your code not only
the formula is right aligned, but
 also the square root symbol is mirrored.

 By the way, I couldn't find "bidi-001.tex" on ConTeXt Site, would you
please let me know where can
 I get it?

 Thanks,
 Mingranina

Assuming that you use math consistently ...

\starttypescript [mathdigits] [all]
     \resetfontfallback [mathdigits]
\stoptypescript

\starttypescript [mathdigits] [arabicindic]
     \definefontfallback [mathdigits] [dejavusansmono] 
[0x0660-0x0669] [check=yes,force=yes,offset=digitsnormal]
     \definefontfallback [mathdigits] [dejavusansmonobold] 
[0x0660-0x0669] [check=yes,force=yes,offset=digitsbold]
\stoptypescript

\starttypescript [mathdigits] [extendedarabicindic]
     \definefontfallback [mathdigits] [dejavusansmono] 
[0x06F0-0x06F9] [check=yes,force=yes,offset=digitsnormal]
     \definefontfallback [mathdigits] [dejavusansmonobold] 
[0x06F0-0x06F9] [check=yes,force=yes,offset=digitsbold]

\definefontsynonym[MathRoman][file:xits-math.otf][features=math\mathsizesuffix,goodies=xits-math,fallbacks=mathdigits]
\stoptypescript

\setupbodyfont[dejavu]

\starttext

     $3+2=5 \quad \bf 3+2=5$

\stoptext

I'm not sure yet how to organize such things in a predefined typescript.

In the next beta you can do this (bidi-006.tex):

\usetypescriptfile[mathdigits]

\usetypescript [mathdigits] [xits-dejavu] [arabicindic]

\setupbodyfont[dejavu]

\starttext
     $3+2=5 \quad \bf 3+2=5$
\stoptext

Of course we need to add more combinations.

 Dear Hans,
 Hello

 With the above code the digits are not changed to persian. For your
information I have
 attached the source, log, and PDF files.

 Please note that I have changed '\setupbodyfont[dejavu] to
\setupbodyfont[dejavusans]
 because the font 'dejavu' is not installed on my system.

 Thanks,
 Mingranina

The following example from Hans worked in my system:

\usetypescriptfile[mathdigits]

\usetypescript [mathdigits] [xits-dejavu] [arabicindic]

\setupbodyfont[dejavu]

\starttext
   $3+2=5 \quad \bf 3+2=5$
\stoptext

The DejaVu fonts are shipped with your context installation and you can use them
with \setupbodyfont[dejavu], when you write \setupbodyfont[dejavusans] context
uses Latin Modern because there is no typeface with the name “dejavusans”.

 Dear Wolfgang Schuster,
 Hello

 The above code works on my system too, but in text mode the digits
are still in English.

 Do you know in which files are these typefaces defined? I want to use
them as sample
 files and define my own typefaces (if I can at all).
