A compiler front end for Oberon-0.
NOTE: Coberon is an Academic Project and it is still WIP.

$ make all

Where in.txt is the test input.

master : A simple lexer and parser.
implement-ast : Adds on to master by implementing a basic AST for a subset of the grammar along with a Symbol Table.

master branch:

$ ./parser [-t] -f

implement-ast

$ ./parser [-t] [-a] [-s] -f

• -t Print the tokens extracted from the input by the lexer.
• -a Print the Abstract Syntax Tree.
• -s Print the contents of the Symbol Table.
• -f Input File (Mandatory)

The project has a lot of scope for enhancements, namely:

• Extending support for the AST and Symbol Table to the entire Oberon-0 grammar.
• Implementing a Symbol Table for multiple scopes.
• Including better Error Recovery methods.
• Implementing a backend for the Compiler using LLVM.

I intend to make Coberon into a fully functional Oberon-0 compiler and all contributions are welcome.
