Re: [Dev-luatex] [lltx] The explanation of \directlua in the manual

Note that the expansion of \directlua is a sequence of characters, not of tokens, contrary to all TeX commands. So formally speaking its expansion is null, but places material on a pseudo-file to be immediately read by TeX, as etex's \scantokens.

For a description of print functions look at section 4.13.10.

Is that really true? When you assign catcodes (catcode tables) to the print functions, TeX's behavior is different from scantokens. I have never used scantokens, so I am not 100% sure. Take for example: tex.print(-2, "\\def\\foo{abc}") will not define \foo. While you have referenced the section with the print commands, I think that the description is misleading. Patrick
