[NTG-context] \setupmathematics with stylealternative not working
Hi,
It seems that, with the latest beta, the \setupmathematics with
stylealternative is not working.
I tried
\setupbodyfont[lucidaot]
\setupmathematics[stylealternative={calligraphic}]
\starttext
\startTEXpage[offset=3bp]
$\mathcal A$
\stopTEXpage
\stoptext
and got the attached output lcm.png. This is not the curly A I would
expect. The one I expect is the one that can be seen on top of page 9
in https://tug.org/store/lucida/lucida-amsmath.pdf.
I also noticed that the example file that I have seen earlier on this
list, pasted below, does not seem to change anything.
Has anything changed?
/Mikael
% second example
\setupbodyfont[lucidaot]
\starttext
$x
^{i \leftarrow 0 = ∅}
_{\setmathfontalternate{arrow}
\setmathfontalternate{dotless}
\setmathfontalternate{zero}
i \leftarrow 0 = ∅}
$
$x
^{i \leftarrow 0 = ∅}
_{\setmathfontalternate{arrow,dotless,zero}
i \leftarrow 0 = ∅}
$
\setupmathematics[stylealternative={arrow,dotless,zero}]
$x
^{i \leftarrow 0 = ∅}
_{i \leftarrow 0 = ∅}
$
\stoptext

Hi Gour,
sorry for my delayed reply.
I’m still behind the environment itself, although I realized that these
may not be relevant to everybody. I store the new commits in a private
repository.
I use the XML handling (generating the XHTML with pandoc) in ConTeXt for
almost all the documents I compile with ConTeXt. I think this is the way
to go.
My environment is only an example. You may write another one for your
own needs, you don’t have to use mine.

I use extended Markdown even for typesetting a ConTeXt introduction in
Spanish (http://www.aprender-context.tk/).
But there are some basic features that I miss from extended Markdown:
- A lightweight syntax for language (such as [Deutsch]{:de}).
- The ability to place the table of contents.
- The ability to place the footnotes/endnotes.
There may be others, but these are the three ones that first came to my
mind.

There are other options, but LaTeX is a real problem for the development
of pandoc, because many times users expect pandoc as a layer that spares
them the actual dealing with LaTeX.
(La)TeX input sources and XML markup are diverse, this is why I think
that pandoc should generate PDF documents from XML sources (and forget
about (La)TeX support).
But this is only my personal opinion. I hope it might help.
Cheers,
Pablo

Re: [NTG-context] Pretty printer for matlab
Hi Marco, Thanks! I hadn't tries [syntax=scilab], but I just did it and it works exactly as expected! However I could not edit the file scilab.vim which sits (on my machine) in /usr/share/vim/vim80/syntax/scilab.vim Meanwhile, out of curiosity I modified the two files buff-imp-lua.mkiv buff-imp-lua.lua written by Hans, by naming them (temporarily) buff-imp-scilab.mkiv buff-imp-scilab.lua and then by saying \usemodule[buff-imp-scilab] \definetyping[scilab][option=SCILAB] I could obtain an approximate good result… But since the keywords in Lua and Scilab are quite different, I could not change some of the settings (for instance in Lua the cosine function is called math.cos while in Scilab it is cos: I could not change appropriately the list of such keywords…). I think for the time being it is simpler for me to use your solution with \usemodule[vim] \definevimtyping[scilab][syntax=scilab] Thanks again, Best regards: OK > On 21 Feb 2019, at 15:31, Marco Patzer wrote: > > On Thu, 21 Feb 2019 15:10:27 +0100 > Otared Kavian wrote: > >> Thanks for pointing to that module, which I didn't know because I >> never use vim… I just tested it and seems fine, but I would need to >> modify some of the keywords of Matlab in order to adapt them to >> Scilab.

For me, both compile. However (2) does not work.
1. Variable names x and y are special and cleared before
every graphic. This is related to the fact that “z" is
defined as a shortcut for "(x,y)”. Both of these are
traditional.
Every metapost graphic does at least this at its start:
save x,y;
currentpicture := nullpicture;
currentpen:=defaultpen;
so pair xx[]; would have worked just fine.
In general, I would advice to stay away from single-letter
variable names inside MPinclusions, and use CamelCase
to avoid clashes with metafun internals.
2. You need a bigger pen to actually see the dots even if
you change the variable name. :)
Best wishes,
Taco

More generaly, which kind of variables cannot be stored in
\startMPinclusions ?
those that are likely to clash later
\startMPinclusions
vardef MyStuff =
numeric u;
u:=1mm ;
path p ;
p:= (0,0) -- (150u,0) -- (150u,95u) -- (0,95u) -- cycle ;
pair x[] ;
x[0]:= (20u,90u) ;
x[1]:= (40u,90u) ;
x[2]:= (90u,90u) ;
x[3]:= (140u,90u) ;
enddef ;
\stopMPinclusions
\startreusableMPgraphic{test}
save p, u, x ;
MyStuff ;
draw p ;
for i=0 step 1 until 3 :
drawdot x[i] ;
endfor ;
\stopreusableMPgraphic
\starttext
\reuseMPgraphic{test}
\stoptext
but in your case you could as well put the inclusions in the test
graphic itself
\startreusableMPgraphic{test}
save p, u, x ;
numeric u;
u:=1mm ;
path p ;
p:= (0,0) -- (150u,0) -- (150u,95u) -- (0,95u) -- cycle ;
pair x[] ;
x[0]:= (20u,90u) ;
x[1]:= (40u,90u) ;
x[2]:= (90u,90u) ;
x[3]:= (140u,90u) ;
draw p ;
for i=0 step 1 until 3 :
drawdot x[i] ;
endfor ;
\stopreusableMPgraphic
\starttext
\reuseMPgraphic{test}

[NTG-context] troubles with \MPinclusions
Hi,
Why does (1) compile, whereas (2) doesn't?
I can't understand why can MPinclusions store path and not pairs.

x[1]:= (40u,90u) ;
x[2]:= (90u,90u) ;
x[3]:= (140u,90u) ;
\stopMPinclusions
\startreusableMPgraphic{test}
draw p ;
\stopreusableMPgraphic
\starttext
\reuseMPgraphic{test}
\stoptext
