You could try the following:
lpeg = require "lpeg"
function replace(s,this,that)
local trans = lpeg.Cs(((lpeg.P(this) / that) + lpeg.P(1))^0)
return trans:match(s)
end
print(replace("target string","get","ball"))
print(replace("100% efficiency with 20% effort","%"," per cent"))
print(replace("ababababababa","ababa","xx"))
Yes, it has a dependency on LPeg. But it's simple, and it works as
expected, without any problems of escaping "special" characters.
