A compiler (or interpreter) has a few parts. A parser converts a file full of source code into a data structure. An interpreter traverses that data structure and executes the appropriate commands for each significant node in the structure. A compiler transforms that data structure and emits something else. Perhaps this other is object code for a specific processor or perhaps it's binary code for a virtual machine or perhaps it's source code for another language entirely. If you look at compiling and implementing languages this way, you already know the general technique. (everything is a compiler). Improve your skills with Modern Perl: the free book.
