Byte to Byte
A multi-language source-to-source transpiler that converts code between 10 programming languages using a four-stage compiler pipeline — built with zero dependencies for the CSE 332 Compiler Design course at Daffodil International University.

Compiler Pipeline
All six classical compiler phases implemented in four functions
1 Source Code
2 parse()
3 analyze()
4 optimize()
5 emit()
6 Target Code
parse() — Lexical & Syntax Analysis (22 node types, 10 language matchers)
analyze() — Semantic Analysis (symbol table, scope stack, 30+ type inference rules)
optimize() — Constant folding, dead code elimination, unused variable detection
emit() — Code Generation (10-target emitter, 200+ stdlib rules, per-node error recovery)
analyze() — Semantic Analysis (symbol table, scope stack, 30+ type inference rules)
optimize() — Constant folding, dead code elimination, unused variable detection
emit() — Code Generation (10-target emitter, 200+ stdlib rules, per-node error recovery)
