MIDL compiler

1. compiler design

1.1 Token Analysis

According to the regular expressions of different Token types, design the NFA firstly.
transform NFA to DFA.
use double switch-case to implement state transformation in DFA.

1.2 Syntax Analysis

design abstract syntax tree
use recursive descent to implement the context-free grammars.
generate syntax tree to text files.

2. usage

2.1 requirement

IDEA
Java1.8

2.2 script

put MIDL code files into inputFile folder
run CompilerTest.java in src folder
