How'd i loop through every string.gmatch in a string then replacing the matches with a bytecoded version of that?

How'd I change everything that it matches in the string without changing the non matches?

local a = "\" Hello World! I want to replace this with a bytecoded version of this!\" but not this!"

for i in string.gmatch(a, "\".*\"") do
    print(i)
end

For example I want [["Hello World!" Don't Replace this!]] to [["\72\101\108\108\111\32\87\111\114\108\100\33" Don't Replace this!]]

Solution 
  • local a = "\"Hello World!\" but not this!"

print(a:gsub('"[^"]*"', function(str)
  return str:gsub('[^"]', function(char)
    return "\\" .. char:byte()
  end)
end))
