Usually the unnnumbered headers aren’t part of any ToC, but since you include 
title, you also get the ToC title. (title = unnumbered chapter)

If you need chapters without numbers, use \setuphead[chapter][number=no].
If you need some titles to appear in the ToC, you can use 
\definehead[MyTitle][chapter] etc.

You can also replace \completecontent with \MySpecialTitle{Contents} 
\placecontent[...].

Does that mean that indic scripts/languages are now fully supported? (Or maybe 
just scripts, not languages? Do Hindi or Urdu need hyphenation patterns?) I 
remember this was an open issue.

Can you spot the difference?
I don’t know about fish, but I guess even there a space is not a valid path 
separator.


BTW: For me on MacOS Mojave, installing in texmf-fonts is unreliable, while 
installing in one of the OSFONTDIRs works.

[NTG-context] TOC- removing Contents 0

2020-04-21 Thread jbf 

A simple question, but I have not found an answer to it as yet:

\completecontent does everything it is supposed to, including providing 
the title 'Contents' on the ToC page, but it also gives me as the first 
line in the ToC:


Contents  0

In fact the ToC appears on page 1, but regardless of the page it is 
appearing on, is there a way I can prevent that line from being produced 
as part of the ToC? I assume it would be something I need to do in the 
following setup:


\setupcombinedlist
  [content]
  [list={chapter,section,title,subject,subsection}]
\setuplist[chapter][style=normal,alternative=b, before=]

Grateful for any help with this,

Julian

Didn’t it work for you in Fedora?

This works for me with LMTX in Fedora.

Add to ~/.bashrc "export OSFONTDIR=~/.fonts/:/usr/share/fonts/" (log out
and log in) and repeat the three other steps from my previous message.

This should work for you (provided that you installed the fonts in any
of the directories added to OSFONTDIR.

I hope it helps,

Pablo

PS: you can also avoid adding anything to ~/.bashrc by adding soft
symlinks for each font to tex/texmf-fonts/. But you have to add the
links to each font file, not to any directory (for some strange reason,
this doesn’t work in Fedora [at least, for me]).

[NTG-context] Setting up macvim in mac os catalina to work with LMTX

2020-04-21 Thread Jan-Erik Hägglöf 
Hi !

I am curious about testing macvim and it seems doing fine in edit mode. But how 
do i set up the typesetting engine?

As far as I understand, there is, the command :ConteXt with guidance from the 
wiki https://wiki.contextgarden.net/Vim 

But I do not understand how to customize it to be directed to the path to my 
engine

I’ve installed the LMTX in /Users/janneman/context-osx-64/



The installation works fine in TeXshop but still an error shows up in macvim 
and the message dissappears very quick so there is not much time to read the 
cause of error.

I have created the subdirectory .vim/ftplugin/ and put the context.vim file 
there
also the corresponding in .vim/compiler/context.vim 

which is copied from the program located in 
/usr/local/Cellar/macvim/8.2-163/MacVim.app/Contents/Resources/vim/runtime

So, how do I get this up and running?

Thanks in advance

Regards

/Janne

Hi Hans, thanks.

I am completely in the dark why your intersection_point works (and thus if it 
will keep working in all circumstances).

I’d like to understand what is going on here. Why does intersection_point work 
where cutafter does not? After all, both are based on the same 
intersectiontimes primitive to find the intersection and they should thus find 
the same one: the ’perfect’ intersection which is the end point of the path 
that is to be cut. 

I’d like to understand this, because otherwise I might run into the same 
problem again later with slightly different paths involved. The first algo that 
I was using worked fine in most cases, as well, then I created one that worked 
with paths with ‘internal spikes’ and now I run into this where two comparable 
situations behaved differently and my question copied the one that didn’t work. 
And while this example from you works, I need to have something that is 100% 
reliable.

What METAPOST comes with is:

path cuttings;  % what got cut off

tertiarydef a cutbefore b =  % tries to cut as little as possible
  begingroup save t;
  (t, whatever) = a intersectiontimes b;
  if t<0:
cuttings:=point 0 of a;
a
  else: cuttings:= subpath (0,t) of a;
subpath (t,length a) of a
  fi
  endgroup
enddef;

tertiarydef a cutafter b =
  reverse (reverse a  cutbefore  b)
  hide(cuttings:=reverse cuttings)
enddef;

secondarydef p intersectionpoint q =
 begingroup save x_,y_; (x_,y_)=p intersectiontimes q;
 if x_<0: errmessage("The paths don't intersect"); origin
 else: .5[point x_ of p, point y_ of q] fi endgroup
enddef;

What is in MetaFun is:

boolean intersection_found ;

secondarydef p intersection_point q =
begingroup
save x_, y_ ;
(x_,y_) = p intersectiontimes q ;
if x_< 0 :
intersection_found := false ;
center p % origin
else :
intersection_found := true ;
.5[point x_ of p, point y_ of q]
fi
endgroup
enddef ;

The thing I can think of is cutting a bit, trying if it still intersects and if 
it does repeat and if it doesn’t take the previous result. I can’t rely on the 
length of cuttings being 0, because this is true in the case of no intersection 
(cuttings equals (0,0)) as well as a ‘perfect’ intersection at the end of the 
path (cuttings is the point at the end of the path). I could rely on cuttings 
being the path (0,0) but how do I compare paths (and not pairs)?

G 

Pretty deep into MP now. Even looked up the reference in John Hobby’s manual to

You have to update the font cache, since the font isn’t found, according
to the following message:

The easiest way to achieve that is:

1. Remove "/home/gour/opt/lmtx/tex/texmf-cache/luatex-cache/".
2. Run "mtxrun --generate".
3. Run "context t.tex"

Now the glyphs should be there.

I hope it helps,

I understand that the font was not set... tried with your example...

Hello!

I'm working on a small presentation for an upcoming video meeting and started
writing some points in Markdown. After using Pandoc to convert I noticed that
*.pptx file does contain everything, but if I try with ConTexT, then Devanagi
and some diacritics are missing.

By inspecting *.pdf file produced by: Pandoc --> PPTX --> LibreOffice --> PDF

I can see that Lohit-Devanagari font is used for Sanskrit and I have it
installed on my Fedora (fc32) desktop machine.

Here is the test file:

what is required to make ConText (lmtx) typeset it?


You have to set a font which has the required glyphs but you can also 
use different fonts for both scripts and combine them.

The path to cut after is a triangle with the base horizontal and the 
path to cut is a vertical line. The top of the triangle is the endpoint 
of the line and is selected as intersection by cutafter. This happens 
also if I reverse the triangle path, strangely enough. I have an 
alternative cutting algorithm, but that cuts as long as the length of 
cuttings is not 0, which is the case at the top too, so it won’t cut 
further.


I need a reliable algorithm to make a ‘maximum cutafter’. What might be

Re: [NTG-context] animation using \startuseMPgraphic

2020-04-21 Thread Jeong Dal 
Dear Hans,

I have not experienced a bottleneck when running ConTeXt.
It is stable and fast. 

I am satisfied with ConTeXt except there are many features and commands which 
are not explained.
Frankly speaking, I don’t need that much commands for my job. 
Also it is not the problem because there are many experts who willingly give 
the solutions in the list mail

I appreciate you and your team.

Best regards,

Dalyoung
