Hi, I tried it. Very nice :)

One small fix: if(args.length<1) {
should be: if(args.length<2) {
because args[0] == executablepath

Best regards,
Daniel

yes right, I didn't see this mistake, not tested a lot:)

If the grammar is getting more complex, re2c places some "unsigned int" into
the code. Under Unix I'll got around with

re2c -i lexer.re | sed s/unsigned\ int/uint/ > lexer.d

hope it helps
