Yet-Another-Programming-Language

Minimal interpreter for a small university language implemented with PLY (lex/yacc).

Prerequisites

• pip install ply

Quick start

1. Install dependency: pip install ply

2. Run the interpreter on a source file: python interpreter.py test_cases\variables.txt

Included test cases (examples)

• test_cases\variables.txt
• test_cases\structs.txt
• test_cases\expressions.txt
• test_cases\standard_output.txt

Notes

• The interpreter script constructs the lexer and parser from the lexer.py and parser.py modules.
• If you edit grammar or parser code and want PLY to regenerate tables, remove parsetab.py (it will be recreated) or set write_tables=True in yacc call.
• Usage: python interpreter.py
