Simple Lang Compiler

This repository contains the implementation of a compiler for SimpleLang, a custom-designed programming language. The compiler translates SimpleLang code into assembly code for an 8-bit CPU.

Project structure

src folder contains the implementation of the Lexer, Parser and Code Generator

lexer.cpp -> Implements the Lexical analysis and converting the file into a token stream
lexer.h -> Header file for the lexer
parser.cpp -> Implements the parser to convert the token stream into an AST
parser.h -> Header file for the parser
codegen.cpp -> Implements the code generation to traverse the AST and map to the assembly instructions of the 8-bit computer
codegen.h -> Header file for the code generation

The data folder contains the sample Simple Lang programs that can be used to test the compiler

Quickstart

Build the project

make

Compile a sample program

./simp /path/to/program

The assembly is generated to a .asm file in the same folder as the source code.

Note: As of now there is no assembler for the generated assembly so we will leverage the assembler provided by the 8-bit computer

Clone the 8-bit computer

git clone https://github.com/lightcode/8bit-computer

Build the computer

make build

Assemble the generated simple lang assembly

./asm/asm.py /path/to/assembly > memory.list

Run the 8-bit computer on the program

./computer
