[NTG-context] Math: Nested Cases?

[Weber, Matthias]

Hello,

Is it possible to nest cases in math, like so:

\starttext
\startformula
x=
   \startcases[align={right,left},distance=3pt]
   \NC  a \NC =
   \startcases[align={right,left},distance=3pt]
   \NC  1 \NC  \text{case  a1} \NR
   \NC  2 \NC  \text{case  a2} \NR
   \stopcases
   \NR
   \NC b \NC =
   \startcases[align={right,left},distance=3pt]
   \NC  3 \NC  \text{case  b3}\NR
   \NC 4  \NC  \text{case  b4}\NR
   \stopcases
   \NR
   \stopcases
\stopformula
\stoptext

I get an error about a missing $ when I try a nested start/stop-cases.

Thanks,

Matthias

[NTG-context] MKIV to LMTX (enumerations)

[Weber, Matthias]

Dear List,

After staying with a frozen MKIV version for time-critical work for a while, I 
took the plunge and ran one of my longer math-heavy documents through LMTX. To 
my delight, it mostly looks fine or trivially fixable.
There is one problem I have with enumerations. The spacing between them in LMTX 
is notoriously smaller than in MKIV.

I bet there is a parameter I can set to tweak that? Below is a MWE with output 
for both engines.
Thanks!

Matthias

Re: [NTG-context] Vertical lines in matrices

[Weber, Matthias]

Hi Aditya,

Ideally I would like to be able to typeset blocks in block matrices visually 
separated, as for instance is done in

https://tex.stackexchange.com/questions/23853/specific-blockmatrices/23857

My current solution for just vertical lines below has the drawback that it uses 
the standard delimiter \vert for the vertical line(s),
which is too thick for my taste.

Thanks,

Matthias

Re: [NTG-context] Vertical lines in matrices

[Weber, Matthias]

Thanks Jeong,

I was aware of this. While there is no solution that adds vertical lines into 
matrices, one can juxtapose two (or more) of them with
properly chosen delimiters, like so:

\definemathmatrix
  [bvmatrix]
  [left={\left(\,},right={\ \right\vert}]

\definemathmatrix
  [rbmatrix]
  [left={\left.\,},right={\,\right)}]
  
\starttext

\startbvmatrix
\NC 0 \NC  0\NC  0 \NR
\NC 1 \NC  0\NC  1 \NR
\stopbvmatrix
\startrbmatrix
\NC  0 \NR
\NC  1 \NR
\stoprbmatrix

[NTG-context] Vertical lines in matrices

[Weber, Matthias]

Dear List,

I am trying to get vertical (separating) lines into matrices, as is possible in 
tables:

\starttext
\startformula
\left(
\starttable[|c|c|c|]
\NC 0 \NC  0\VL  0 \FR
\NC 1 \NC  0\VL  1 \FR
\stoptable
\right)
\stopformula
\stoptext

But my parentheses don’t fit, and I am not sure whether using tables in math 
mode is the proper way of doing things.
\startmatrix seems to ignore a \VL.

Any. suggestions?

Thanks,

Matthias

Re: [NTG-context] Update problems

[Weber, Matthias]

Update:

The page setup works after Hans’ fix. Thanks, that was a relief.
I still don’t know what’s going on with PDF inclusion. The ones that cause 
trouble are kind of old (from 2005), and I could “upgrade”
Them manually and things work now for this document. I have others that might 
cause problems, too. Unfortunately, the error message only tells which page 
couldn’t be flushed but not what figure is causing issues. Going through a 
hundred figures and trying whether they work is somewhat painful.

A more verbose error message would be helpful, or a hint what has changed with 
pdf import.

Thanks,

Matthias

[NTG-context] Update problems

[Weber, Matthias]

Dear List,

After a while I decided updating my ConTeXt installation to ConTeXt  ver: 
2019.01.07 10:07 MKIV beta  fmt: 2019.1.7.

With an old document of mine I ran into two issues so far: Some of my old pdf 
images are not accepted as figures anymore.

Example:

\starttext
\externalfigure[cardioid.pdf][width=1.5in]{Cardioid}
\stoptext
Using the following pdf which is version 1.4 



cardioid.pdf
Description: cardioid.pdf

More recent PDFs (1.5)seem to work.

Secondly, paper setup seems to require a new kind of massage.

\setuppapersize[S6][S6]

\starttext
\dorecurse{10}{\input knuth}
\input knuth
\stoptext

produces



test0.pdf
Description: test0.pdf

On the other hand, the garden version looks ok. What could be wrong on my end?

Thanks!

Re: [NTG-context] future versions

[Weber, Matthias]

I have an entirely different suggestion, possibly fitting the description of a 
possible  “lean” version.

One important feature of TeX has been the longevity of the documents. This is 
of course of little interest to those of us who
typeset a book/journal for publishing and care little about it when it’s done. 
But there is an interest in keeping the documents available in the long term,
meaning decades and possibly centuries (making assumptions about the human race 
here).  TeX has survived the transition from dvi/ps to pdf, and it is probably 
fair
to assume that pdf won’t be around forever. But it is probably also fair to 
assume that there will be straightforward ways to generate from TeX sources 
documents in a
future PDF replacement. 
This is in particular of concern in the scientific community where 
mathematical/physical/chemical formulas and diagrams are very hard to parse 
semantically
(which, admittedly, might change in the future, too). For instance, the 
preprint server at arXiv.org has been storing scientific preprints since 1991, 
preferably in TeX or LaTeX.
It would be an enormous benefit if the arXiv would accept a ConTeXt version. 
Scientific journals might then follow suit. 
At the moment I believe they use LaTeX from TeXLive 2016. 

It is of course a question whether a potentially much larger user base is 
desirable, because it likely means more requests for support/documentation etc.

In any case, I would very much appreciate another “frozen” release like MK II 
that one can use for documents that need to be  retypeset over years
(like my lecture notes that need an update every few years).

When I comment out the before/after, I get paragraph breaks before and after

Re: [NTG-context] Instalation ConTeXt to MAC - newbie problem

[Weber, Matthias]

Hi Jaroslav,

could you explain a bit more what you mean by "the installation will fail”?

What error message do you get at what stage?

You need to make sure that you have write permission to the installation 
directory; anything inside your home directory should be safe.
Also, as a general precaution, make sure the path to your installation 
directory doesn’t contain unusual characters.

Re: [NTG-context] Instalation ConTeXt to MAC - newbie problem

[Weber, Matthias]

Here is what I do:

Tetrahedron:ConTeXt matthias$ mkdir ~/context
Tetrahedron:ConTeXt matthias$ cd ~/context
Tetrahedron:context matthias$ rsync -ptv 
rsync://contextgarden.net/minimals/setup/first-setup.sh .
first-setup.sh

sent 38 bytes  received 3636 bytes  1469.60 bytes/sec
total size is 3525  speedup is 0.96


and the files are definitely there. Do you have a space in /context directory? 
Then you might need apostrophes.

Hello Matthias.
Thank you for the quick response. During installation, no error occurs, even 
seems that rsync copied without error message first-setup.sh to my 
%HOME/context directory. When then I look into this directory, then there is no 
file. Subsequently command sudo sh ./first-setup.sh reports nonexistent file or 
directory. I tried to install it into your Applications folder too (I have 
administrative access), but not in this way I have not done.

(As you say: home directory should be safe and path no occure any problematic 
characters. My home directory is "hajtmar")
