[luatex] \input from Lua.

[Paul Isambert]

Hello all,

Is there a way to make TeX read a file from the Lua interface? The best 
I can do is to issue:

tex.print("\\input{" .. file .. "}")

or something similar. But that is most inconvenient, and anyway it 
doesn't work in an initialization script. (What I do in such a script is 
register a function in "process_input_buffer" that returns the first 
line prefixed with the desired \input statements, and then unregisters 
itself at once. But that's horrible, it looks like a dirty trick!)

Best,
Paul
