Re: [NTG-context] Coding for new Unicode characters
Just to say that I seem to have resolved this (& properly I hope).
I read these two pages:
https://www.contextgarden.net/Faking_characters
https://source.contextgarden.net/tex/context/base/mkiv/enco-ini.mkiv?search=textcedilla
and have included the following with my setups:
% Additional Characters
\definecharacter llowmacron {\buildtextmacron l}
\definecharacter Llowmacron {\buildtextmacron L}
\definecharacter nlowmacron {\buildtextmacron n}
\definecharacter Nlowmacron {\buildtextmacron N}
\definecharacter rlowmacron {\buildtextmacron r}
\definecharacter Rlowmacron {\buildtextmacron R}
\define\lLM{\llowmacron}
\define\LLM{\Llowmacron}
\define\nLM{\nlowmacron}
\define\NLM{\Nlowmacron}
\define\rLM{\rlowmacron}
\define\RLM{\Rlowmacron}
This seems to do it, although if there is a better way please feel
free to say.
Best, Richard

I am using Latin Modern Roman to typeset some proceedings and need the
following characters in regular, italic, and small caps:
Character: ṉ U+1E49
Name: LATIN SMALL LETTER N WITH LINE BELOW
Character: Ṉ U+1E48
Name: LATIN CAPITAL LETTER N WITH LINE BELOW
Character: ḻ U+1E3B
Name: LATIN SMALL LETTER L WITH LINE BELOW
Character: Ḻ U+1E3A
Name: LATIN CAPITAL LETTER L WITH LINE BELOW
Character: ṟ U+1E5F
Name: LATIN SMALL LETTER R WITH LINE BELOW
Character: Ṟ U+1E5E
Name: LATIN CAPITAL LETTER R WITH LINE BELOW
These characters are available in Computer Modern Unicode (although
not, it seems, in small caps). Still, I would prefer to still with LM.
I'm wondering if there is a way in Context to set up these characters
on the fly, say with something along the lines of "newunicodechar"?
\newunicodechar{}{}
\newunicodechar{ā}{\accent"0304 a}

Re: [NTG-context] background color of text in contour(former: ntg-context Digest, Vol 186, Issue 61)
Dear Hans, Thank you for the fix. Background color is OK now. A new problem in the caption: Since width of the figure is narrower than the width of the line "x = [0,12.555]; y = [-6,6];”, “y =“ is written over 12.555. Is there any option to suppress the caption x, y since there are numbers of x and y in the figure already? Thank you.

Re: [NTG-context] How to use in Metafun, a function defined in Lua

As a simple example consider the following:

Here \type{document.myfunction(n,x)} is $\sin(nx)$. For instance when $n = 2$
and $x = 355/113$ we have:
\type{document.myfunction(2,355/113)}
$=\cldcontext{document.myfunction(2,355/113)} \sim 0$.
\startplacefigure[title={Nothing works\dots}]
\startMPcode{GridAxis}
numeric gu ; gu = 5mm ; % gu = graph unit
draw image (
draw function (1,"x","document.myfunction(2,x)", % <-- this does not
work
% draw function (1,"x","sin(2*x)", % <-- this works
-355/113,355/113,.01)
scaled gu
withpen pencircle scaled .075pt
withcolor darkred ;
) xsized .7TextWidth ;
\stopMPcode
\stopplacefigure
\stoptext
%%% end lua-metafun-example.tex
Here one sees that the function « document.myfunction » is well defined in Lua
and is known in ConTeXt, but I cannot use it in a Metapost code: how can one do
that?
you confuse lua and mp functions
\startluacode
function MP.myfunction(n,x)
return math.sin(n*x)
end
\stopluacode
\starttext
\startMPcode
numeric gu ; gu = 5mm ;
vardef myfunction(expr n, x) = MP.myfunction(n,x) enddef ;
draw image (
draw function (1,"x","myfunction(2,x)",-355/113,355/113,.01)
scaled gu
withpen pencircle scaled .075pt
withcolor darkred ;
) xsized .7TextWidth ;
\stopMPcode
\stoptext
