I use that on Lua2SC (only open, read, close but seek should be easy)
-- function takes a string that behaves like a file to be read
function StrFileOpen(strg)
local strptr = 1
local str = strg
local strfile = {}
function strfile:read(len)
local oldstrptr = strptr
strptr = strptr + len
return str:sub(oldstrptr,strptr-1)
end
function strfile:close(len)
self = nil
return true
end
return strfile
end

Subject: File-like string scanning
I find myself writing my own code for functions string.lines(...) and
string.read(...) so that str:lines and str:read have the same semantics
as file:lines and file:read, except that they are use-once since strings
can't store position.
I can't believe that I'm the first person who has though of doing this.
Any pointer to a module that does it nicely will be appreciated.
