Thank you very much, Hans,

I had already written to Dick Koch before the first replies arrived. He wrote that I could simply use Lua(La)TeX.
So it works with Lua(La)TeX. A self-created lua.engine works and your ConTeXt solution with --runner=mtxrun in the first line works as well.

Best regards
Thomas

Hello,

at the risk of this being the wrong address: can I edit and run Lua with TeXShop?
Does anyone have experience with this?
Or what could be used as an IDE for Lua?

you can try this with

-- runner=mtxrun

as first line in your lua file
