[NTG-context] Reconciling unicode-math with LaTeX2e mathematics

[Maggyero]

Is there a plan to have in ConTeXt the same kind of math behavior that Will
Robertson implemented in the last version of his unicode-math LaTeX package
(\mathrm, \mathit, \mathbf, \symrm, \symit, \symbf, etc.)? Because ConTeXt
currently has the same math/text spacing issues in math mode that the old
unicode-math package had.

Re: [NTG-context] Command definitions in ma-cb-en.tex

Hi all,

this is a stupid question, I fear: In "ConTeXt Mark IV an excursion" in
appendix A I see many command definitions. I browsed the sources of this
document but could not find the point where these list is defined.

I know that in setup-en.pdf there is an even longer list, but I could
not find the source of this document.

Can anyone shed some light on this mechanism?


This is implemented using XML interface. See, for example, cont-en.xml in 
$TEXMF/texmf-context/tex/context/base/interface


The schema is documented at http://wiki.contextgarden.net/Interface.rnc

The XML to TEX mappings are defined in x-set-11.mkiv. The basic usage is

\usemodule[int-load] % synonym to x-set-11
\loadsetups[] % name of xml file

\starttext

\showsetup{command-name}

\stoptext

you need to be more explicit about the problems you encounter (minimal 
examples for instance)


the (unicode) math implementation of context has been around for many 
years now and the basic approach is unlikely to change


of course is something is wrong we fix it (given that it fits within the 
unicode / opentype possibilities)

Re: [NTG-context] Unnumbered subject in TOC, numbered exercises in text

[Sytse Knypstra]

Thank you, Wolfgang,

I changed 'special' into another word and replaced 'incrementnumber=yes' 
by 'incrementnumber=list'.

But the result does still not reach my second goal:
my exercise numbers are still 1 and 1 instead of having chapter number 
prefixes (1.1 and 2.1).

Dear list,



In the following minimal example I would like to have:

- the headings of \special in the toc, unnumbered

- in the text, the numbers of the exercises preceded by the chapter 
number

The first goal is achieved when uncommenting the two options under 
\setuphead,


the latter is achieved when uncommenting only the second option.
How can I realize both simultaneously ?


Thank you in advance,



Sytse

[NTG-context] \rm for greek letters in math mode

[Kate F]

I see the third \delta here as italic, where I would have expected it
to be in roman, as for the "d" example below. Likewise for all greek
letters, I think.

Why is that? How can I have these in roman?

\starttext
\delta $\delta {\rm \delta}$\crlf
d $d {\rm d}$
\stoptext

Thanks,

Re: [NTG-context] meaning of error message?

[Wolfgang Schuster]

Hi, Wolfgang—

at line 34, I have \Query
which is defined:
\definehighlight[Query][color=magenta,style=bold]

There also instances of \emph (\definehighlight[emph][style=italic]) 
at lines 41 and 58.
You have create a minimal example (or provide your source offlist) 
because I wasn’t able to reproduce the error with your code snippet.

Re: [NTG-context] natural tables and columndistance/spaceinbetween

[Wolfgang Schuster]

Alan BRASLAU

In natural tables
http://wiki.contextgarden.net/TABLE

the parameters
columndistance=dimension,
and
spaceinbetween=dimension,
will set the gaps between columns and rows, respectively.

Is there some way of specifying row gaps for specific rows?
For example, say that I only want a gap after the first row.
I tried:

\bTABLE
\bTR [spaceinbetween=.25em]
\bTD 1 \eTD
\bTD 2 \eTD
\eTR
\bTR
\bTD A \eTD
\bTD B \eTD
\eTR
\bTR
\bTD a \eTD
\bTD b \eTD
\eTR
\eTABLE

Alternately, I tried
\setupTABLE [r][1][spaceinbetween=.25em]

but these do not work.


One might think about trying

\bTR [bottomframe=on,framecolor=white,rulethickness=.25em]
...
\eTR

but this presents several problems:
1) When using background=color, the background color gives a hairline
overflow beyond the rule, at least using the pdf viewers that I have on
my computer.
2) there appears to be some interference between setting rulethickness
and columndistance, so that spaces between columns disappear when
putting a thick bottomframe. Of course, one could kludge a column
separation using a rightframe, but this is not satisfactory.
3) The use of a white rule when one really wants to leave some space is
not very satisfying.

Does anyone have any suggestions?
You can use the boffset key to set a different offset value for the 
bottom of the cell.


The correct the position of the frame at the bottom you can use metapost 
to draw

the frame as background graphic.
