Sorry, Jeroen, this was my fault.
A simpler approach to the command above reads:
\savebuffer[list=slides, file=slides.tex]
But then you have to invoke the file as
\typesetfile[\jobname-slides.tex][--purgeall][object=no, width=0pt]
and the output file would read:
\getfiguredimensions[\jobname-slides.pdf]
\dorecurse{\noffigurepages}
{\startTEXpage
\externalfigure[\jobname-slides.pdf][page=\recurselevel]
\stopTEXpage}
I mean, you get hyphen instead of underscore.
I hope it may help,
Pablo

Is there an easy way to write a Context document and also code simpleslides
in the same document so that the simpleslides are automatically added to
the document as for example an appendix? Ie one tex document with Context
code, perhaps with some \input and something like a two-pass job. I was
thinking if the simpleslides could be saved as a number of png images and
then with the recurse add them to the document with placefigure.
"Easy" is an ambiguous term... I can tell you how I do this (I use xml,
but with a bit of code, this can be adapted to TeX documents): I have
the code for the slides and my own comments in the same documents; I
pass a --mode to the compilation to filter and select content. When I
have my presentation as a file "presentation.pdf," I save it and then
have the slides included automatically via a counter, like this:
function xml.functions.combined_slide(t)
i = i + 1
local textwidth = tex.dimen.textwidth
context.page()
context.framed( { width=number.todimen(textwidth), frame="off",
align="middle", height="10cm" },
function() context.externalfigure( { "presentation.pdf" }, { page=i,
width="13cm" } ) end )
context.blank { "line" }
end
So, as others have said: no need to convert to png. Setting up a
workflow takes some time and thought, but once it's in place, it works
very well; I have now used my xml-based workflow for 12 years or so, for
all my university lectures and talks.

Hi Jeroen,
not sure this might help you (I’m not sure you intend a single source
file, in addition to a single PDF document), but here you have:
\startbuffer[slides]
\setuppapersize[CD]
\setupbodyfont[60pt]
\starttext
\dorecurse{25}
{\startmakeup[standard][pagestate=start, style={\ss\bf}, align=center]
Slide \pagenumber
\stopmakeup}
\stoptext
\stopbuffer
\savebuffer[list=slides, file=\jobname_slides.tex, prefix=no]

\startbodymatter
\dorecurse{25}{\input zapf\par}
\typesetfile[\jobname_slides.tex][--purgeall][object=no, width=0pt]

\dorecurse{\noffigurepages}
{\startTEXpage
\externalfigure[\jobname_slides.pdf][page=\recurselevel]
\stopTEXpage}
\stopappendices

BTW, I cannot get simpleslides working with LMTX.

\externalfigure is your friend here and there is no need to convert the
slides to PNG (see above).
Just in case it may help,
Pablo

Re: [NTG-context] Code lua in a table
Dear Hans,
Thank you for new methods!
It would take some time for me to understand them fully.
Learning Lua, metafun, lmtx, wiki is always a challenge for me.
I also wonder where is the boundary of ConTeXt.
I hope that you and all members in this list are well from COVID-19.
Thank you again.

Hi all,
Thank you for your contributions, it allows me to progress.
@Hans and Deal
The code is impressive but does not correspond to the shape of the triangle
that I have to make (by convention).

Re: [NTG-context] Code lua in a table
Dear Fabrice,
You may split Binom(n,k) function into two functions as following:
*
\startluacode
P={}
combi = P
function P.fact (n)
if n <= 0 then
return 1
else
return n * P.fact(n-1)
end
end
function P.ncr(n,r)
return P.fact(n)/(P.fact(r)*P.fact(n-r))
end
combi = {
fact = fact,
ncr = ncr,
}
\stopluacode
**
Your table is actually Pascal’d triangle.
Using the above function, I was able to draw Pascal’s triangles.
Hans helped me to complete it.
I couldn’t wikify it at that time because I don’t know how to. I’ll do it soon.
Here is the whole code for Pascal’s triangle in two different ways using Lua,
Metafun and ConTeXt.
You may enhance the code.
\startbuffer[pt1]
numeric n,r,s,u,dx,dy,tt; u := 1.8cm;
path p, q;
pair A,B,start,now;
A := dir(210)*u;
B := dir(-30)*u;
dy := sind(30)*u;
dx := 2*cosd(30)*u;
for n=0 upto 4:
start := n*dir(210)*u;
for r=0 upto n:
s := n-r;
tt := lua("mp.print(P.ncr(" & decimal n & "," & decimal r & " ))");
now := start+r*right*dx;
dotlabel.top(textext("$\displaystyle {" & decimal n & "\choose" &
decimal r & "} = "& decimal tt & "$"),now);
draw (now+A) -- now -- (now+B);
endfor;
endfor;
\stopbuffer
\startbuffer[pt2]
numeric n,r,s,u,dx,dy,tt; u := 1cm;
path p, q;
pair A,B,start,now;
A := dir(210)*u;
B := dir(-30)*u;
dy := sind(30)*u;
dx := 2*cosd(30)*u;
for n=0 upto 8:
start := n*dir(210)*u;
for r=0 upto n:
s := n-r;
tt := lua("mp.print(P.ncr(" & decimal n & "," & decimal r & " ))");
now := start+r*right*dx;
label(textext("$" & decimal tt & "$"),now);
endfor;
endfor;
\stopbuffer
\startluacode
P={}
combi = P
function P.fact (n)
if n <= 0 then
return 1
else
return n * P.fact(n-1)
end
end
function P.ncr(n,r)
return P.fact(n)/(P.fact(r)*P.fact(n-r))
end
combi = {
fact = fact,
ncr = ncr,
}
\stopluacode
\starttext
\processMPbuffer[pt1]
\blank[big]
\processMPbuffer[pt2]
\stoptext
I hope that it helps.

Dalyoung

which looks nicer.

Now, in context lmtx we can have a different kind of abstraction. We can
do this:
function MP.pascal_ncr_x()
mp.print(ncr(mp.scan.pair()))
end
and then use:
tt := runscript("MP.pascal_ncr_x()") (n,r) ;
Of course one can decide to pick to two numerics instead, like
tt := runscript("MP.pascal_ncr_x()") n r ;
but i leave that as exercise.
% tt := runscript mp_pascal_ncr (n,r) ;
tt := pascal_ncr (n,r) ;
However, we still have the rather verbose runscript here, so we go
further, we register pascal as script:
\startluacode
metapost.registerscript("pascal_ncr",MP.pascal_ncr_x)
\stopluacode
And then define an alias at the metafun end:
\startMPextensions
newinternal mp_pascal_ncr ; mp_pascal_ncr := scriptindex "pascal_ncr" ;
def pascal_ncr =
runscript mp_pascal_ncr
enddef ;
\stopMPextensions
The internal permits this:
tt := runscript mp_pascal_ncr (n,r) ;
while the additional def permits
tt := pascal_ncr (n,r) ;
Now watch out, because we define pascal_ncr here, something
lua.MP.pascal_ncr(n,r) won't work because the last part gets expanded
because that is what mp does (i'll probably cook something for that some
day).
Now, to come back to
"I couldn’t wikify it at that time because I don’t know
how to. I’ll do it soon."
looks like you suddenly have an additional challenge,

Hi Wolfgang,
It works but why did you ask this question since I finally use context ?
Are you sure you want to use context(...) here?
In your first version you used the context function in the loop to print
the output of the Binom but the Binom function used context as well,
this could result in context(context(...)).
How not to display the .0 ?
Format the content of the context function to show only integer values,
e.g. context("%d",Binom(...)).
For more information search for formatter in cld-mkiv.pdf.

Re: [NTG-context] Code lua in a table
Hi Wolfgang,
It works but why did you ask this question since I finally use context ?

How not to display the .0 ?

Don’t use text ;-) That’s a known issue: as soon as your Metapost
code contains text, it will be processed twice. E.g.:
\starttext
\setMPtext{heading:title}{foo}
\startMPcode
show This gets printed twice.;
draw textext( \MPstring{heading:title} );
\stopMPcode
\stoptext
Same for labels, {b,e}tex. See also this thread:

If I'm not mistaken that's the way MP works when text is involved,
it's a two-pass approach. In graphics without text MP has all
information it needs to create the image. The text in MP graphics is
typeset using TeX. After it's typeset MP picks it up in a second
run.

Maintain a vector with the last two elements to check against.

Re: [NTG-context] Code Called Twice?
Hi, typeset using TeX. After it's typeset MP picks it up in a second run. That also explains why the spacing between words is correct (I didn't think MP could typeset text). Maintain a vector with the last two elements to check against. An interesting approach; I used a Boolean flag as per this thread: http://www.ntg.nl/pipermail/ntg-context/2011/056078.html Works as expected.

That’s handy! I added a section on dealing with multi-pass to the
“gotchas” page:
http://wiki.contextgarden.net/Unexpected_behavior#Multipass
There is a subsection about MP at the end.
Btw. the behavior of mfun_trial_run is not very intuitive. I’d
expect it to work like \iftrialtypesetting, but in a single-pass
context it evaluates to true:
\enabletrackers[metapost.showlog]
\starttext
\startMPcode
if mfun_trial_run :
show This should be printed during the trial pass.;
else :
show This should be printed during the final pass.;
fi;
fill unitcircle scaled 1cm withcolor blue;
%label (btex Some label text etex, (0,0));
\stopMPcode
\stoptext
Uncommenting the label yields two passes, as expected.

Re: [NTG-context] Code in contextref-env.tex
I have no idea what the sequences like \v!and \c! etc. mean. Are they references to modes? I asked much the same question on tex.stackexchange.com two months ago, except mine was not so nice and focused. Aditya gave a very nice explanation of what the letters do; clearer than the one on the wiki, I thought. Here's a link straight to his answer: http://tex.stackexchange.com/a/58716/2229 They are used as language-agnostic forms. Using ConTeXt's English format, you'd type \startmarginblock Using ConTeXt's French format, you'd type \demarreblocmarge So to accomodate both, we define variables \s!start -- start or demarre, and \e!marginblock -- marginblock or blocmarge, depending on the language, and then we tell TeX we want to run the command named with the string \s!start\e!marginblock -- startmarginblock or demarreblocmarge. (Example not entirely accurate, I believe the variable for startmarginblock is define holisticaly. But you get my point.) Example of the need for the letter codes, paraphrased from mult-ini.mkiv: Where English uses 'left', in Dutch one finds both 'links' for '(on) the left' and 'linker' for 'the left one'. Hence the letter codes, so we can have \v!left -- links and \c!left -- linker. \c! is for keywords \v! is for value names \s! is for system bits \e! is for elements Hope this helps you in reading the sources!

In practice users don't have to use that convention in their files, unless they are meant to be multilingual. Btw, there is a nice story behind this: - left= 4 tokens - \c!left = 1 token so, when context grew harder than tex's string space (we're talking emtex times) it was also a way to save memory. To some extend it's also faster (less tokens to pass as argument) but at the same time there is a penalty of expanding the 1 into 4. So, in a single lingual interface there is not much gain. Some of the 'struggles with too small engines' has been removed in mkiv as nowadays we have no such constraints. When I introduced the \c! and \v! prefixes context was still dutch and when there came interest from abroad, it had the nice side effect that I could make an (first german, later also english) interface in just a couple of hours (context was smaller at that time). The first module to actually be multilingual was 'ppchtex'.

Hello,
how to translate in context the following plain tex:

{\tt
{\obeylines
{\fgras def} ra():

not a solution, but this works

thanks luigi, it compiles with 'context 2010.01.26' but:
- the def is not in bold
def is bold (you can see it with pdffonts) only it's loaded at
10pt, while body font is 12pt (I believe)
it is true - i saw it just after sending the mail.
- context adds \n between every line.
hmm, If I cut-and-paste to vim I see the same as pdf , ie no extra \n
anyway you can play with interlinespace
ok \interlinespace works
\starttext
\font\fgras = lmmonolt10-bold.otf at 12pt
{\tt\setupinterlinespace[line=1ex]
{\obeylines
{\fgras def} ra():
\ \ \ \ a = 3
\ \ \ \ b = 4
}
}
\stoptext
but remains that every {\bf } introduces a white space;
how to force context to make a backspace ?
my 76 pages of Python code rewritten in plain tex by a python
script are accetabile (compile by pdftex) - so i will try to
thank you to remember me that I'm always on late with python pretty printer ..
it would be fine

Thanks Wolfhang. It goes better, but there is still a little bug:
{\bf def} inserts a white space in front of the line
Compare:
{\bf def} ra():
def ra():
a = 3
b = 4
\startlines
\bold{def} ra():

Re: [NTG-context] code with reserved words
Based on the pretty printer in the wiki, I wrote my own.
If I understood you well, you want a b/w pretty printer
with reserved words bold. The pretty printer is capable
of doing both. An example is attached. Probably missing
is the functionality to control the typesetting of reserved
words in TeX. This is done in the lua code. I didn't mind
up to now. Any feedback is welcome.

If you have the modes defined in a layout.tex you can say in the main file:
\enablemode[times]
%\enablemode[palatino]
%\enablemode[..]
\environment layout.
So by adding the appropriate \enablemode you even do not need to run the
