You can try Pegged, a parser generator that works at

I did, and I got it to work. Unfortunately, the code used to in 
the CTFE is left in the final executable even though it is not 
used at runtime. So now the question is, is there away to get rid 
of the excess baggage?

BTW Here is the code I am playing with.

import std.stdio;

string get_match()
{
  import pegged.grammar;
  mixin(grammar(`
    MyRegex:
        foo <- "abc"* "def"?
    `));

  auto result = MyRegex(import("config-file.txt")); // 
compile-time parsing
  return "writeln(\""~result.matches[0]~"\");";
}

void main()
{
  mixin(get_match());
}
