The MathML spec specifically suggests the use of OverBar; instead
of a literal accent character in situations like this.

For the macron, accent=false should only influence the vertical
placement, not its stretchiness.

Re: [NTG-context] documents to (print and) read

2006-03-30 Thread Taco Hoekwater

Hi,

 Here the very same situation. My question boils down to
 
   Which document should I print, book bundle and read.

In my opinion, you should definately read:

Context, an excursion  http://www.pragma-ade.com/show-man-1.htm
TeXExec manual http://www.pragma-ade.com/show-man-4.htm
Fonts Explainedhttp://www.pragma-ade.com/show-man-6.htm

And I heartily recommend the not-yet-finished but very beautiful:

Typographic Programming http://www.pragma-ade.com/show-man-39.htm

 Sorry for not getting back for almost a month. Both suggestions work

 \startmathformula
   \sum_{%
 \startmathmatrix
   i = 1 \NR i \neq n \NR i \neq m
  \stopmathmatrix

 As Taco mentioned, the spacing is bad.

 \atop gives correct spacing but you need to put subscripts in groups 
 of two.

 \startformula
\sum_{ {i = 1 \atop i \neq n}\atop i \neq m } a_i
 \stopformula

 Moreover, the font size is incorrect in both cases. Compare with the 
 size of the subscript in \sum_{i = 1}.

 Any suggestions?

We would like the possibility to have options while loading
modules, and the cleanest way of doing that is to have an
optional argument to \usemodule, so we can have, e.g.:

   \usemodule[font=GreekTimes,scale=1100][greek]

And in the module:

   \processaction[\moduleparameter\v!font]
  [=]

etcetera. just like a 'normal' parameter.

I know this effect can partially be implemented using modes,
but sometimes a  key=value syntax is much cleaner. This:

\enablemode[GreekTimes1100]
\usemodule[greek]

is not nearly as flexible.

 The MathML spec specifically suggests the use of OverBar; instead

The problem is that it is also specified to which unicode character is  
mapped the entity (http://www.w3.org/TR/MathML2/isodia.html). Actually  
OverBar; is U00AF.

So, the behaviour should not be different when using an entity name and  
the corresponding unicode value. Imagine some XML tool processing an  
original XML mathml code containing an entity name, and simply expanding  
the entity according the MathML DTD. I think that processing the original  
and the expanded code should give the same result.

Of course, using entity names instead of unicode values is better for  
readibility and maintanability, but IMHO it is not a solution to the  
question.

 probably a mismatch between an old format and new tex files

 To Hans,
 No, the formats are all newly generated after the install of cont-tmf.zip.
 The \loadfontfileoncetrue is used in meta-ini.tex  by 
 \def\resetMPenvironment
 but what why is it needed ?

 Does it reload fonts as defined in Context (typescripts) when btex/etex 
 is used in Metapost ??
   
it indeed has to do with that; some low level commands deal with 
efficient processing of mp in between runs

Sorry about that, I was and am busy converting 
my Latex code into Context 
and forgot about this definition. 
I defined \textbf as follows

\def\textbf#1{{\bf #1}}

BTW Taco already gave the answer. Thanks Taco

Thanks

 How do you define \textbf?

No, I explained before that I do not have access to this website due

Luckily I won't have to suffer that difficulty next year.

I do have an old copy of the wiki, but it is difficult to go through
due to how wget got the files.

I guess that in MathML stretchiness is more systematic and should apply to  
most characters, provided that they can stretch  
(http://www.w3.org/TR/REC-MathML/chap3_2.html). In this doc it is said:

By default, most horizontal arrows and some accents stretch horizontally.

 now an implementation needs to adapt to math or text (or just gamble
 since it may be that i want a non stretchable macron over x+y+z); my
 guess is that as a result, many implementations are more complex than  
 needed

 From my little window (since I don't know how it works internally) I would  
say that in mathml stretchiness is required in things like mover or  
munder, if the character allows it, and depending on stretch attribute.  
But it's sure that it does not make things easier.

 (btw, in pure text, it's still not clear if the macro glyph sould be
 chosen or a stretchable hrule)

What is not clear to me is if unicode explicitely allows a combination of  
a non spacing mark (accent) and a *group* of characters. In the  
specification I've only seen that it can apply to a base character. If it  
can apply only to one character, a glyph seems enough.

 (i think that one problem of unicode/xml/mathml is that it is used in
 typesetting systems but not in all aspects is designed (or used) to
 facilitate high end results; therefore a 24/32 bit tex still needs to

Yep!

[NTG-context] definesortkey

2006-03-30 Thread Johan Sandblom
I have a document in Swedish with an index. Merely setting
mainlanguage[sv] does not give correct sort order. I remember doing
something like

\startlanguagespecifics[sv]
\definesortkey[å][z][a][å]
\definesortkey[ä][z][b][ä]
\definesortkey[ö][z][c][ö]
\stoplanguagespecifics

but this no longer has any effect and gives

TeXUtil | unknown entry k in line k {sv}{ec}{å}{z}{a}{å}
TeXUtil | unknown entry k in line k {sv}{ec}{ä}{z}{b}{ö}
TeXUtil | unknown entry k in line k {sv}{ec}{ö}{z}{c}{ö}

from newtexexec (this is on a current windows standalone context)

What is the correct code?

Regards, Johan

I have the following tabs in Adobe Acrobat 7 under Windows XP:

But I have a feeling that Creator (in my version of Acrobat it's
written Application) usually really stands for the program (so ConTeXt
 version would be more appropriate to stand there).

Here it's written:

Application: ConTeXt/user/filename.tex (which doesn't really make much sense)

For the original problem, I guess Mojca is closest to the
actual problem. She herself has a continuing fight with
btex/etex and textext(). If you can, you should try to post
a 'recipe': make a minimal example in a clean directory,
post that here along with what commands to run, and all
of the results (logs, temp files) you get.
