I am not a "wizard" yet, but someday I want to be really good at
Here is my recommendation for getting started:
0) know C or C++...and understand pointers.
1) download, read, learn, play with 'flex'.
flex is free software and it allows you
to take a bunch of characters and form
2) download, read, learn, play with 'bison'.
bison is free software and it allows you
to take a bunch of tokens and form
statements and meaningful blocks of code.
3) know about your basic data structures,
like hash tables and trees.
4) write many "programs" in your imaginary language.
When you have a good idea of what you would like
it to be like, you can express it in the regular
expressions and BNF notation with flex and bison
5) you may want to start with a simple language first.
i.e., implement a primitive calculator language or
something. Also, you may want to build an INTERPRETER
first, because to write compilers you must understand
machine language to write COMPILERS.
