Lua stuff is not saved in the format unless you put in a lua bytecode

Okay, how would I do this? As it's only one function, I think some
awkwardness setting things up is acceptable. AS I'm looking at this from a
LaTeX-like point of view I'd like the format to be self-contained (no
additional files required for it to at least load and function "as
advertised").
Hi Joseph,
I had a quick stab at this (with essentially no prior experience in
LuaTeX programming). The following seemed to work for me and does what
you want:
Yes. A somewhat more generic solution is this:
\directlua
{
tex.enableprimitives('',tex.extraprimitives ())
lua.bytecode[1]=function ()
function pdfstrcmp (A, B)
if A == B then
tex.write("0")
elseif A < B then
tex.write("-1")
else
tex.write("1")
end
end
end
lua.bytecode[1]()
}
\everyjob{\directlua{lua.bytecode[1]()}}
\long\def\pdfstrcmp#1#2{%
\directlua
{%
pdfstrcmp("\luaescapestring{#1}","\luaescapestring{#2}")%
}%
}
