[NTG-context] Which version to use for MathML?

2012-12-01 Thread Chen Shen
Hi all,

I tried a few mathml examples with 2012.05.30 and the latest beta (test
script attached).

The 20120530 version fails with eqn1, which uses presentation mathml, but
works with eqn using content mathml.
The latest beta generates doesn't work with either equations.

I see a lot of mathml related changes recently, with the file x-mathml.mkiv
come and go away.
Which version should I go with to get presentation mathml work?

thanks and regards,
shenchen

[NTG-context] problem with t-filter/t-vim

2010-10-19 Thread Chen Shen
Hi Adityam,

I am using the t-filter/t-vim module, and got stuck with two problems with
it.
1. everything works fine if there is only one \definevimtyping declaration.
However, if i declare two of them, as in the following:

%%%
\definevimtyping[PythonCode][syntax=python]
\definevimtyping[CPPCode][syntax=cpp]

\startPythonCode
... % Code A
\stopPythonCode

\startPythonCode
... % Code B
\stopPythonCode
%%%

The counter for the temporary files is never incremented. So there is only
jobname-externalfilter-PythonCode-0.tmp in the directory.
Consequently, Code B appears twice in the produced PDF, while Code A never
appears.

2. Every line in the Python code becomes a new paragraph in ConTeXt. I
wonder if this could be changed.
I am using \setupwitespace[line], so the spacing between two lines of source
is too large.

I am using the dev/ branch in the github repository.
Thank you very much.

regards,
shenchen

[NTG-context] multiple flow charts in the same document

Hi all,

I want to place multiple flow charts in the same document.
However, connection comments displays correctly in the first chart, but
disappears in the second chart.

Below is a minimum example adapted from the wiki.

I am using mkiv,

This is LuaTeX, Version beta-0.62.0-2010082314

Any suggestions? Thanks a lot!

[NTG-context] mathbold greek letters

2010-09-02 Thread Chen Shen
Hi all,

First I admit that I've never understood the typescript part of ConTeXt...
I've been using the following recipe for boldmath.
The latin letters appears fine in bold italic font, but the greek letters do
not appear.
---
\definetypeface [boldmath] [mm] [boldmath] [latin-modern] [modern]
[encoding=texnansi]
\setupbodyfont[10pt]

\starttext
$a b c \alpha \beta \phi$

$\bi a b c \alpha \beta \phi$
\stoptext
---

Looking at the log file, I found the following error message:

---
Missing character: There is no α (U+03B1) in font LMMath10-Regular!
Missing character: There is no α (U+03B1) in font LMMath10-Regular!
Missing character: There is no β (U+03B2) in font LMMath10-Regular!

Missing character: There is no ϕ (U+03D5) in font LMMath10-Regular!

Apologize for dumb questions.
I wonder why LMMath Regular is looked-up here, I thought we should be
looking-up LMMathItalic10-Bold?

Thanks a lot.

 Are you using MkIV? If so, an easier solution will be to use an opentype
 math font, like xits or cambria or asana math. Then you can simply use

 $\bf a \alpha$

 to get bold math.

Re: [NTG-context] bib module problem with mkiv

2009-11-23 Thread Chen Shen
Hi all,

I tried digging mailing list and the source file. I am afraid that the
bibl-tra module has a few problems:

==
\usemodule[bibl-tra]
\setupbibtex[database=xampl]
\starttext

\section{aaa}
\cite[a]
\placepublications

\section{bbb}
\cite[b]
\placepublications

\stoptext
===

1. Documentation says that without a criterium option, only bibl cited in
local section is included in the list, but actually all cited bibl are
listed.

2. In MkII, the solutioin to problem 1 is to use [criterium=section] in
\placepublications, but this does not work in MkIV.

3. \placepublications only works once in the document, the second time you
call this macro, it outputs nothing.

I wonder if there is a chance to see this fixed in the forthcoming beta.
Otherwise, I will need to revert to some (very) old version, as I need
per-chapter reference lists. Thanks a lot~

shenchen

 A cleaner way to achieve the same output is

 \starttext

 Sorry, this should have been \placeformula.


  \startformula \startalign
 \NC a_1 x + b_1 y \NC = c_1 \NR[eq:1]

It worked great with MkII and old versions of MkIV.


However, it failed in recent versions of MkIV (e.g. 2009.11.2).

Apparently, the \makesectionnumber and \rawreference macros have be removed.

I wonder if anyone can give pointers on how to fix this.

Thanks a lot.

[NTG-context] possible to run minimal in cygwin?

2009-11-02 Thread Chen Shen
Hi all,

I wonder if it possible to run the MSWin version of context-minimal under
Cygwin.
I want to use Makefile and other unix tools to automate my build process.

I tried modifying the context/tex/setuptex script, and manually set the
platform variable to mswin,
but when I ran context.cmd, I saw the following error message. The
texmf-cache path actually exists.
Any hint? Thanks a lot!

==begin cut===

Should I create the cache path /cygdrive/c/usr/docs/context/tex/texmf-cache?

Re: [NTG-context] possible to run minimal in cygwin?

2009-11-02 Thread Chen Shen
Hi Bryant,

Thanks a lot! I got it working with your suggestion.
The exact sequence was:
 1. install ConTeXt in DOS cmd
 2. run setuptex.bat in DOS cmd
 3. enter cygwin by running cygwin.bat
 4. in cygwin prompt, run   context.cmd test.tex

Our docbook-pdf/html flow was developed in unix. But I need to port it to
Windows now for my colleagues.

shenchen

  I am doing exactly the same thing as you want. I believe your problem is
 in keeping your worlds (Windows/Cygwin) straight. It appears that you have
 installed minimals “inside” cygwin (depending on whether your /usr directory
 is your cygwin /usr directory).



 I installed minimals “normally”, as it is a Windows application. I ran the
 context setups from Windows. Then I can build with no problems from within
 cygwin by running the minimals cmd files (although you must specify the
 extension from within cygwin). I did not have to modify any files at all.



 So far, no problems. Just remember to keep your path information in
 “Windows” format, not cygwin.

I got a strange unknown reference problem with the following simple
example:

\startformula
a^2 + d^2 = c^2

I am using luatex beta-0.43.0-2009081911
Got the same problem with context version from 2009.6.14 to the latest beta.
I also tried deleting everything and re-install the minimal dist., but still
can't solve the problem.

I wonder if anyone else has this problem, or it only occurs to me. Thanks a

 If you still want to use the last beta use the following patch,
 Hans removed a few lines of code from enco-ini.mkiv and this
 breaks the \in command because it is redefined later in the core

   \def\Micro {\dimensionprefix{\iftextdimensions u\else\hbox{µ}\fi}}

 The \hbox is needed because \fam11 is using ec encoding, I think.
 (and that is problematic in its own way, but let's not go there)


Yes. This change to (mu latin) worked. Thank you so much for the
detailed explanations.
I think it is preferable to use upright greek letters in units.
The shape of (mu latin) in the latin modern font isn't the prettiest
design, but is still better than mixing italic mu with other upright
letters in units.
Besides, I guess, (mu latin) instead of u can be used in text-mode units?

 Hi all,
 \Micro in the units module failed, while \Nano and \Milli works fine.
 $\mu$ works, so it doesn't look like a font problem.
 The following code works with pdftex/MarkII, but fails under Luatex
 0.29beta/MarkIV.

 \usemodule[units]
 \starttext Hello world! $1\Micro\Meter$ $1\Micro\Second$
 \stoptext

 Any hints? Thanks a lot!
