Hi,


Thank you all. The commands of Wolfang work perfectly.

The fallback mechanism is even easier than virtual fonts.

ConTeXt is truly great.


Thank you,

Joas.

Thank you for the clarification, Wolfgang.

I think this is a really nice feature.

1. You don’t need “force=yes” because this a default setting.

2. When you want additional setups you have to change the fourth argument to

     \definefallbackfamily […] […] […] [preset=math:uppercasenormal,force=yes]

   because

     \definefallbackfamily […] […] […] [math:uppercasenormal]

   is only a simpler way to write

     \definefallbackfamily […] […] […] [preset=math:uppercasenormal]

   This is possible because I can check if the argument is a assignment or a keyword
   and when you have a keyword I use it as argument for the preset key.

Re: Baskervald ADF Virtual Math Fonts

[Mikael P. Sundqvist]

Hi Joas,

I do not have that font to try (and sorry if I misunderstand the
question), but the following works to get Minion italic as
"lowercaseitalic" and so on instead of Pagella. Maybe using the names
instead of the glyph ranges work for you aswell?

\definefontfamily [mainface] [rm] [Minion Pro][opticalsize=yes]
\definefontfamily [mainface] [ss] [Myriad Pro][opticalsize=yes]

\definefallbackfamily [mainface] [math] [Minion Pro]
[math:uppercasenormal] [force=yes]
\definefallbackfamily [mainface] [math] [Minion Pro]
[math:uppercaseitalic] [force=yes]
\definefallbackfamily [mainface] [math] [Minion Pro]
[math:lowercasenormal] [force=yes]
\definefallbackfamily [mainface] [math] [Minion Pro]
[math:lowercaseitalic] [force=yes]
\definefallbackfamily [mainface] [math] [Minion Pro]
[math:digitsnormal]    [force=yes]
\definefontfamily [mainface] [math] [TeX Gyre Pagella Math]

Best regards, Mikael

You need a newer version of ConTeXt to get that command.


Ok. You may also answer my question:


Let us consider the statememt:



\definefontfallback [BaskervaldOverPagella] [file:BaskervaldADFStd-Italic]   [0x1D44E-0x1D467] [\check=yes,force=yes]




I understand it as: “Replace the glyphs 0x1D44E-0x1D467 (mathematical a-z)

of the source font with the glyphs from Baskervald italic having the same code.”

But how do you map 0x1D44E-0x1D467 of the source font to 0x61-0x7a.

How do you say:  “Replace the glyphs 0x1D44E-0x1D467 (mathematical a-z) of

the source font with the glyphs  0x61-0x7a (text a-z) from Baskervald italic”?

For example something like:


\definefontfallback [BaskervaldOverPagella] [file:BaskervaldADFStd-Italic]   [0x1D44E-0x1D467] [0x61-0x7a] [\check=yes,force=yes]


Thank you,

Hello,

Thank you for your answer.




The command \definefallbackfamily seems not to be a typescript-level command.

Let us try \definefontfallback.




Let us consider the statememt:




\definefontfallback [BaskervaldOverPagella] [file:BaskervaldADFStd-Italic]   [0x1D44E-0x1D467] [\check=yes,force=yes]




I understand it as: “Replace the glyphs 0x1D44E-0x1D467 (mathematical a-z)

of the source font with the glyphs from Baskervald italic having the same code.”

But how do you map 0x1D44E-0x1D467 of the source font to 0x61-0x7a.

How do you say:  “Replace the glyphs 0x1D44E-0x1D467 (mathematical a-z) of

the source font with the glyphs  0x61-0x7a (text a-z) from Baskervald italic”?

For example something like:


\definefontfallback [BaskervaldOverPagella] [file:BaskervaldADFStd-Italic]   [0x1D44E-0x1D467] [0x61-0x7a] [\check=yes,force=yes]




Other question: What do check, force and offset means?




Thank you.


Best regards,

Joas.

Replacing certain symbols in a math font with a text font is very easy with the fallback mechanism
and the \definefallbackfamily command makes things even simpler:

Baskervald ADF Virtual Math Fonts

[joasyannick]

[-- Attachment #1.1: Type: text/plain, Size: 1006 bytes --]




Hello,


Thank you for the answer.


>if you have a proper opentype math Font…


As you know, Baskervald doesn’t come with an open type math version.

Moreover the mapping mechanism works well with open type text fonts and is
powerful and very general. It’s my prefered way of solving my problem. So I reiterate

my questions:


Question 1:

Where do I define my own vector mapping? Should I modify ConTeXt’s source code in the math-ttv.lua file? How do I define my own baskervald-math.lua and what should I write in it (for example for mapping Pagella’s upright mathematic glyphs to Baskervald’s upright glyphs)?


Question 2:

I am forced to put the goodies file baskervald-math.lfg in Book/Volume1/Chapter1. When I put it in Book and compiled chapter1.tex separately, ConTeXt failed to find it. What should I do to have the file baskervald-math.lfg in the Book directory and make ConTeXt find it when invoked from Book/Volume1/Chapter1.


Thank you.

Joas.

the virtual math font mechanism is normally used for type one math fonts 
overlayed over open type text fonts

if you have a proper opentype math font you can better use fallbacks 
(the fallback mechanism for math looks the same as for text but is 
implemented differently)

see type-imp-euler.mkiv for an example

Baskervald ADF Virtual Math Fonts

[joasyannick]

[-- Attachment #1.1: Type: text/plain, Size: 3007 bytes --]

Hello,


I am going to solve my problem here:



http://tex.stackexchange.com/questions/123647/from-xelatexs-unicode-math-to-contexts-typescript


with virtual math fonts. I use Baskervald ADF instead of Libertine. I was pleased to see that the following files produced effects:


Extract from environment file fonts.tex: ------------------------------------------------

\startenvironment fonts

    \starttypescript [math] [fonts]
        \loadfontgoodies[baskervald-math]

    author = "author",

    }
}

Now I have two questions.


The first and most important question is: Where do I define my own vector mapping? Should I modify ConTeXt’s source code in the math-ttv.lua file? How do I define my own baskervald-math.lua and what should I write in it (for example for mapping Pagella’s upright mathematic glyphs to Baskervald’s upright glyphs)?


The second question is this. I have the following Project structure:


Book (root directory)

Book/book.tex (Project file)

Book/fonts.tex (environment file)

Book/Volume1 (subdirectory)

Book/Volume1/volume1.tex (product file)

Book/Volume1/Chapter1 (subsubdirectory)

Book/Volume1/Chapter1/chapter1.tex (component file)


I am forced to put the goodies file baskervald-math.lfg in Book/Volume1/Chapter1. When I put it in Book and compiled chapter1.tex separately ConTeXt failed to find it. What should I do to have the file baskervald-math.lfg in the Book directory and make ConTeXt find it when invoked from Book/Volume1/Chapter1.


Best regards,

Joas.
