I have a few silly questions about
tex.print()
To produce
$\sqrt{2}=1.4142135623731$
it should be enough to write
tex.print("$\\sqrt{2}=" .. math.sqrt(2) .. "$") this is because \\ can mean anything, for instance it may expand to \par or \crlf or ..
May be I do not understand this right, but I thought that '\' is luas escape character and tex.print() returns '\' not '\\'. So TeX sees no macro '\\' which could expand to whatever.
it depends on where you code lives ... in a lua file, then \\ is an escape, in \directlua (or \ctxlua cum suis), then it's a tex cs your mail only shows the one line of code so we have to guess
there is a \luaescapestring primitive which catches things like quotes
Can you make a little example of usage?
tex.print("\detokenize{$\sqrt{2}=}" .. math.sqrt(2) .. "$")
well, if you put that in your document, you'l get a typeset tex.sprint, so i assume that tis is wrapped in \directlua or so?
Could not find the definition of \detokenize.
