favorite












In LuaTeX, using the directlua primitive (within a standard LaTeX2e setup)



directlua{tex.print("Hello World!")}


will produce "Hello World!" to the output PDF.



On the other hand, in expl3 code



ExplSyntaxOn

lua_now:e { tex.print("Hello~World!") }

ExplSyntaxOff


left "HelloWorld!" (no space between Hello and World!) to the input stream.
