Compiler Project Using Antlr.

Using Antlr the following program can nearly compile a program in the language 'TINY' (denoted with .micro extension). The compiler currently has 2/4 steps complete towards a fully working compiler.

Lexer:

Using the Micro.g4 we denote our grammar to get a list of valid tokens from a .micro file. WHILE is a keyword, + is a Operator.

Parser:

Again, using the Micro.g4, we now define the syntax of our grammar in a list of rules. What follows a '(' what should come after KEYWORD PROGRAM, etc.

Symbol Table:

This step still needs work. We are using a stack in combination with a hash map to define the scope of our code along with the occurrence of entities in our program such as; function names, variables, etc.

Code Generation:
