Compiler Construction Project

Created a compiler for a custom language in C

Steps to Execute

1. To compile all the files, run the make command.
2. To run the compiler on a file 'input.txt' and storing the Parse Tree as an output in a file called 'output.txt' with a buffer size of 50, run ./runCompiler input.txt output.txt 50

Features Implemented

• Twin Buffer
• Lexer
  1. Lexical Error Handling
  2. Keyword Handling
  3. Tokenization
• Parser
  1. Automatic First & Follow of the Grammar
  2. Parser Error Handling
• Parse Tree Generation
• Abstract Syntax Tree Generation
• Symbol Table
• Type Checking
• Semantic Analyzer (Incomplete)

Approximate DFA for the language

Structure of the files

All header files with the 'Def' suffix are being used to implement the structure, while rest of the header files contain function declarations.
