Because we need to understand the esoteric compiler theory and technology, and one of the most critical and very difficult part is to define the rules of the new language and to parse with them.To solve this problem, there have been many theories , techniques and tools . These tools can be roughly divided into two categories: one is parser generator, another is to write the parser by hand with or without a parser library. > No tool will change the fact that the *design* of a language is a complex task. Long before you get to implementing anything, you have to decide what your language will look like, what its special features are, how it distinguishes one thing from another, etc etc etc. That work won't change based on the tool you use - or rather, if it DOES change, it's because the tool is too restrictive. First write some code in your new language, then and only then work out how to implement an interpreter/compiler. The first part of the job is pretty complex (and extremely important), and tools don't come into play till the second. ChrisA
