We are involved in e.g. typesetting math schoolboooks and for some

of keeping your source clean (clever xml editor environments sometimes 
mess up). As with tex documents one just hits a button to get a preview.

Interesting…I also have need for footnotes within footnotes and hit that

recently. :-)

Well, considering that ConTeXt can do much more than AsciiDoc, maybe for
regualr web content (blog posts, shorter articles etc.) I could simply
use Markdown without even going to AsciiDoc which is interesting option
only in case of being able to server as single-source format.

True, that conclusion comes from my side. I'm pretty sure that all
needed XMP entries are properly set, so chances are high, that the error
is on their side. But we will (hopefully) see.
Also: If Acrobat isn't right, what tools are left for validation?

Thanks. Is there a way to change font family locally in math mode?
For example how can I use serif if sans serif is the default math font?

I played a lot with these setups and have questions.
I use this font setting:

\definefontfamily [docuf] [rm] [TeX Gyre Bonum] 
\definefontfamily [docuf] [ss] [TeX Gyre Adventor]
\definefontfamily [docuf] [tt] [Latin Modern Mono] [features=none]

\definefallbackfamily [docuf] [mm] [Tex Gyre Adventor] 
[preset=math:uppercasenormal]%,scale=.6]
\definefallbackfamily [docuf] [mm] [Tex Gyre Adventor] 
[preset=math:uppercasebold]%,scale=.6]
\definefallbackfamily [docuf] [mm] [Tex Gyre Adventor] 
[preset=math:uppercaseitalic]%,scale=.6]
\definefallbackfamily [docuf] [mm] [Tex Gyre Adventor] 
[preset=math:uppercasebolditalic]%,scale=.6]

\definefallbackfamily [docuf] [mm] [Tex Gyre Adventor] 
[preset=math:lowercasenormal]%,scale=.6]
\definefallbackfamily [docuf] [mm] [Tex Gyre Adventor] 
[preset=math:lowercasebold]%,scale=.6]
\definefallbackfamily [docuf] [mm] [Tex Gyre Adventor] 
[preset=math:lowercaseitalic]%,scale=.6]
\definefallbackfamily [docuf] [mm] [Tex Gyre Adventor] 
[preset=math:lowercasebolditalic]%,scale=.6]

\definefallbackfamily [docuf] [mm] [Tex Gyre Adventor] 
[preset=math:digitsnormal]%,scale=.6]
\definefallbackfamily [docuf] [mm] [Tex Gyre Adventor] 
[preset=math:digitsbold]%,scale=.6]
\definefallbackfamily [docuf] [mm] [Tex Gyre Adventor] 
[preset=math:digitsitalic]%,scale=.6]
\definefallbackfamily [docuf] [mm] [Tex Gyre Adventor] 
[preset=math:digitsbolditalic]%,scale=.6]

\definefontfamily [docuf] [mm] [TeX Gyre Pagella Math]

\setupbodyfont[docuf,24pt]

1. If I want to use a scale factor is it possible the give the scale factor by 
using
the preset a,b,c,d,x,xx values? Or I must specify the scale factors as numbers?

2. Scaling occurs compared to which font in the definition list?

3. I found that if I write \definefontfamily [docuf] [mm] [TeX Gyre Pagella 
Math]
before \definefallbackfamily lines, the latter have no effect. Is this normal?
Shouldn't the order of definition lines be indifferent?

4. If I write a paragraph with different font size, how can I scale the 
embedded math
too automatically? For example if I write

\placefigure[here]{Figure title}{\ss\tfxx
A B C D \math{E~F~G~}}

A B C D is typeset with small fonts but E F G not; it will be huge compared to
A B C D. I can't manually scale the math part because it is inserted here
by chemfig module and I can't redefine how it typesets fonts.

Thanks in advance,

bcsikos

Dear list members,

I create all my MetaFun drawings in a separate environment file where 
each individual drawing sits inside a start/stopbuffer. This allows me 
to easily use those drawings in all my documents using 
\processMPbuffer[name]. Works just fine.


However, I also wish to have all the drawing available in a pdf file 
(each drawing on a separate page). This allows me to split the pdf and 
use the drawing elsewhere (e.g. in a Powerpoint) or include page(s) 
from the pdf in another document.


The below MWE represent my MetaFun drawings file.
The idea is that by uncommenting the \enablemode[makepdf] I can create 
the pdf file with drawings. It seems however that startMPpage does not 
accept buffers (I also tried processbuffer and processMPbuffer).


Is it possible to somehow make this work?

You can use

\startTEXpage
\processMPbuffer[…]
\stopTEXpage

but loading a buffer in MPpage doesn’t work because the content of the 
environment
is just passed to MetaPost and buffers can’t be loaded inside MetaPost 
code unless

Hans adds a function for this, e.g.

\startMPcode
buffer("mybuffer")
\stopMPcode

writing an asciidoc parser that directly maps to context is not that

[[terms]]

["glossary",id="terms"]
List of Terms

where

\startglossary[reference=terms,title={List of Terms}]
