wrote the parser from scratch.

basicly all you have to do is understand and make use of the structure the language has, but it is by no means easy=)

im pretty experienced with writing parsers,

i''ve written my own XML parser, and now my own C parser.

so im not sure if it was ''easy'' it really only requires knowledge of how to enumerate a string, and what to look for under certain conditions.

there was one thing that i found exceptionaly valuable in the parsing function, and i mentioned it above, normalizing the code.

taking,code which could be extreamly weirdly formated.

if(x == 2 + 5){

i = "cool" ;
}

and turning it into

if(x==2+5){i="cool"

by striping out all whitespace characters,

when doing this it is very important to watch out for string literals, when striping whitespace, if you encounter a " you should stop striping whitespace, until you encounter another "(one which is not escaped like \"), otherwise you will destroy string formating.

having a ''no white space'' code string to parse is much simpler and doesnt require code to skip through possible whitespace, which can clutter up the parser.

hehe, yes i use 2 sweeps, normalization, compiliation.
