Re: [NTG-context] Bold Greek Math with Fourier Font

I think I've found my problem (finally).  The problem is in
'type-enc.tex' I referred to the standard text fonts for
Fourier-Math-Letters and Fourier-Math-Letters-Bold instead of the true
math fonts.  I believe this is how ConTeXt is configured in its
default...  In any case, 'type-enc.tex' should contain:

\starttypescript [math] [fourier] [default,ec]
  \definefontsynonym [Fourier-Math-Letters] [futmi] [encoding=ec]
  \definefontsynonym [Fourier-Math-Letters-Italic]  [futmii]
  \definefontsynonym [Fourier-Math-Symbols] [futsy] 
  \definefontsynonym [Fourier-Math-Extension]   [fourier-mex]

\stoptypescript

\starttypescript [boldmath,bfmath] [fourier] [default,ec]
  \definefontsynonym [Fourier-Math-Letters-Bold] [futmib] [encoding=ec]
  \definefontsynonym [Fourier-Math-Letters-Italic-Bold]  [futmiib]
  \definefontsynonym [Fourier-Math-Symbols]  [futsy] 
  \definefontsynonym [Fourier-Math-Extension][fourier-mex]

\stoptypescript



Hmm... As I said, I don't know much about context. But consider that 
Math-Letters is an operator font. If you choose futmi as your opérator 
font, something like \cos will be italicised !


Now (one of) the difference between fourier and computer modern is that 
capital greek is in the italic font not in the operators font.


This is handled in math-fou.tex:

\definemathsymbol [Gamma]   [alpha] [mi] [00]



Note that futmi, and futmii (or futmib futmiib) are two versions of the 
same font (same encoding): the difference is that in futmmii all is 
slanted (even greek caps), and in futmii caps are upright (roman and 
greek) and lowercase are slanted.


If you want command definitions in math-fou.tex to be used even in 
boldmath, you must change type-spe.tex by referencing the fou math 
collection in boldmath too.

Hi all,

Does anyone know how to setup fourier to have boldfaced symbols (both
greek and roman) using the Fourier font?  I've read through the 
Mixed Normal and Bold Math  doc, but I cannot seem to get bold to

work at all with the Fourier font.  Heck, I cannot even get the
boldmath definition to stop substituting with cm!


I know fourier very well, but I am *not* a context user...

I think you have to modify type-spe.tex

\starttypescript [math,boldmath] [fourier] [special]
  \usemathcollection[fou]
\stoptypescript

%% Was
%% \starttypescript [math] [fourier] [special]
%% \usemathcollection[fou]
%% \stoptypescript

Then just add

in type-enc.tex

\starttypescript [boldmath] [fourier] [default,ec]
  \definefontsynonym [Fourier-Math-Letters-Bold] [futb8t] 
[encoding=ec]

  \definefontsynonym [Fourier-Math-Letters-Italic-Bold]  [futmiib]
  \definefontsynonym [Fourier-Math-Symbols] [futsy]
  \definefontsynonym [Fourier-Math-Extension]   [fourier-mex]
\stoptypescript

in type-sync.tex

\starttypescript [boldmath] [fourier] [name]
  \definefontsynonym [MathRoman] [Fourier-Math-Letters-Bold]
  \definefontsynonym [MathItalic][Fourier-Math-Letters-Italic-Bold]
  \definefontsynonym [MathSymbol][Fourier-Math-Symbols]
  \definefontsynonym [MathExtension] [Fourier-Math-Extension]
\stoptypescript

It seems to work, but it is not strongly tested...
