I wonder whether it would make sense to enable a style option in \setuplanguage. Having to use setups is maybe too difficult for newcomers and style is a common option in other commands.

Henri,
1. I added a sanity test (angle(origin) is undefined);
2. it is probably more efficient to calculate the angle twice than to allocate
storage;
3. primary b;
4. then I created the variant arc (as in a bow) taking a delta (the tangent of
an angle).

Re: [NTG-context] xml in lua advice ?
Hi,

What I am mostly trying to do is to have as much of the xml processing in lua
as possible.
>

> \starttext
>
> % here is your missing mwe
Yes, sorry about that. My question was intended to be more of an
documentation-related one.
Using your MWE as guideline, my minimal file looks like this:
% BEGIN ENVIRONMENT
\startluacode
function xml.functions.document(t)
lxml.flush(t)
end
function xml.functions.b(t)
context.start()
context.bf()
lxml.flush(t)
context.stop()
context("{}")
end
function xml.functions.section(t)
context.section("{")
lxml.flush(t)
context("}")
end
\stopluacode
\startxmlsetups mysetups % to be converted to lua later
\xmlsetfunction {main}{document}{xml.functions.document}
\xmlsetfunction {main}{section} {xml.functions.section}
\xmlsetfunction {main}{b} {xml.functions.b}
\stopxmlsetups
\xmlregistersetup{mysetups} % to be converted to lua later
% XML normally in separate file
\starttext
\startbuffer[test]
some bold title
\stopbuffer
\xmlprocessbuffer{main}{test}{}
\stoptext
% END EXAMPLE
I know it would be simple to write e.g.
\startsetups xml:section
\section{\xmlflush{#1}}
\stopsetups
but I was aiming for a simple, clean-looking CLD as style setup of the XML
document. I doubt I could explain your MWE to one of my coworkers, as I
hardly understand it myself :)
What I was really hoping for was something like the fictional:
function xml.functions.section(t)
context.section(lxml.process_into_context_string(t))
end
or some CLD extension so that it would actually understand
function xml.functions.section(t)
context.section(lxml.flush(t))
end
I hope this makes more sense now. Unless something magical is possible,
it seems my best bet is to stick with \startsetups instead of lua for
these cases, just to make sure I can explain to the rest of the office
what is going on.
Thanks,
Taco

Re: [NTG-context] xml in lua advice ?
My 2 cents:
local xmlflush = lxml.flush
local function text_or_xml(...)
for i,v in ipairs(arg) do
if "table" == type(v) then
xmlflush(v)
else
context(v)
end
end
end
function xml.functions.heading(t)
text_or_xml( "\\section{" , t , "}" )
end

xelatex had no problems to use the font.
Is this an error in the font or in the fontloader?
it works ok here with luatex
but ... do you use luajittex?
No (neither with lualatex).

The fonts *are* large, and my computer is quite old, so it could be
a hardware problem, but I'm wondering a bit about the message
otf reader > invalid index in single format 1: 65353 -> 67212
sure, but afaiks that's taken care of, but it still loads ... so given
the computer maybe a memory issue? can you run with the task manager
open? it does need some mem when serializing so maybe your virtual mem
is not enough?
the first time caching takes some 23 sec on my (also not that new)
machine but after that loading takes way less time (some .4 sec)
maybe use the ttc files instead: sourcehansans-normal.ttc

… lots more duplicates
and a successful run despite all that.
Note, however, that the luatex process tops out at nearly 3GB RAM
use while generating the cached version, which could be a problem
on 32-bit operating systems.
Best wishes,

it works ok here with luatex
but ... do you use luajittex? if so, forget about it as luajit has some
limitations wrr memory and loading tables from stack (adapting the code
to deal with that will make it a mess and we can't even be sure how long
luajit will be around and supported in luatex anyway)
