Compiler Design

Repo contains a compiler that can be used to compile basic JavaScript code, such as for loops, if constructs, etc.

Phase 1 - Lexer

• lex.l is the file used as a lexer. The lexer generates tokens from the given input and removes comments.
• To run the file, run the following commands
  $ lex lex.l
$ gcc lex.yy.c

Phase 2 - Parser

• Parsing is done by a YACC file, yacc.y. It takes the tokens sent by the lexer and generates a parse tree as well as a symbol table, while performing a syntax check.
• To run the file, run the follwing commands
  $ yacc yacc.y $ gcc y.tab.c
