ng

Steps to add new syntax:

• Check if requires new keyword:
  • include/token.hpp for token types
  • src/lexer.cpp for token represesntations
  • src/reserved.inc for reserved tokens
• Check if requires new AST:
  • include/ast.hpp for new AST type
  • src/ast/ast.cpp for method implementations, especially accept() and ~T()
  • include/ast.hpp for new AST visitor method
  • src/visitor.cpp for implement AST visitor method
  • src/ast/serializer.cpp for AST type serialize/deserialize

Steps:

1. Create new token type (if not exists)
2. Add lexer method to lex the token
3. Check if reserved tokens were used and update
4. Add lexer test
5. Add new AST type
6. Implement the parser
7. Add parser test
8. Add new visitor method for the AST type
9. Implement interpreter
10. Update examples for the new syntax
11. Update integration test to include new syntax example file
12. Implement serializer
