Here is a start...
--lhf
function split(s)
local t={[0]=s,n=0}
gsub(s,"%s*(%S+)",function(x) tinsert(%t,x) end)
return t
end
function AWK(f)
if type("BEGIN")=="function" then BEGIN() end
while 1 do
local l=read()
if l==nil then break end
f(split(l))
end
if type("END")=="function" then END() end
end
AWK(function (t) foreach(t,print) end)
