Re: File-like string scanning

["Victor Bombi" <sonoro@...>]

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
