Parse-Craft

Parse-Craft is a compiler construction project for CS F363: Compiler Construction at BITS Pilani.
It implements the front-end modules of a small programming language:

• Lexical Analyzer
• Grammar Loader
• FIRST and FOLLOW Set Computation
• LL(1) Parse Table Construction
• Predictive Parser
• Parse Tree Generation
• Basic Panic-Mode Syntax Error Recovery

The project is written in C and can be built using the provided makefile.

Project Scope

This repository implements the lexical analysis and syntax analysis phases of the compiler.

The language supports constructs such as:

• Primitive types: int, real
• Constructed types: record, union
• Type aliases using definetype
• Global and local variable declarations
• Assignment statements
• Arithmetic expressions
• Boolean expressions
• Conditional statements
• Iterative statements
• Function definitions and function calls
• Input/output statements
• Return statements

Semantic analysis, type checking, intermediate code generation, and target code generation are outside the scope of this stage.
