$ python test_compiler.py compile <file with micro_lang> --grammar=<file with productions> --start_sym=<start symbol> --out=<file to compile to>

• Where the <file with micro_lang> is the path to the file containing micro language.
• Example test files can be found in the ext dir.
• If --grammar is not specified it will default to the productions contained at ext/compile_grammar
• If --start_sym is not specified it will default to <system_goal>
• If --out is not specified it will default to ouput/compile.out
• Prints out status of Compiler as it consumes the input, including the parse stack, semantic stack, remaining input, symbol table and generated code.
• NOTE: you may want to pipe the output of this command to less

$ python test_compiler.py compile ext/test_compile1 --grammar=ext/compile_grammar --out=ouput/compile.out

$ python test_compiler.py parser_driver <file with micro_lang> --grammar=<file with productions> --start_sym=<start symbol>

• Where the <file with micro_lang> is the path to the file containing micro language.
• Example test files can be found in the ext dir.
• If --grammar is not specified it will default to the productions contained at ext/test_grammar1
• If --start_sym is not specified it will default to <system_goal>
• Prints out status of Parser Driver as it consumes the input, including the stack, parser action, and remaining input.
• NOTE: you may want to pipe the output of this command to less

$ python test_compiler.py parser_driver ext/test_parser1 --grammar=ext/test_grammar1 --start_sym='<system_goal>'

$ python test_compiler.py table_generate <file with productions> --start_sym=<start symbol>

• Where the <file with productions> is the path to the file containing micro language productions.
• Example test files can be found in the ext dir.
• If --start_sym is not specified it will default to <system_goal>
• Prints out Predict Table as derived from the Predict and Follow sets found earlier.
• NOTE: you may want to pipe the output of this command to less

$ python test_compiler.py table_generate ext/test_table_gen --start_sym='<system_goal>'

$ python test_compiler.py predict <file with productions> --start_sym=<start symbol>

• Where the <file with productions> is the path to the file containing micro language productions.
• Example test files can be found in the ext dir.
• If --start_sym is not specified it will default to <system_goal>
• Prints out Derives Lambda, First Sets, Follow Sets, and Predict Sets for each production to std out.

$ python test_compiler.py predict ext/test_predict2 --start_sym='<system_goal>'

$ python test_compiler.py grammar <file with productions>

• Where the <file with productions> is the path to the file containing micro language productions.
• Example test files can be found in the ext dir.
• Prints out list of extracted production information to stdout in a list.

$ python test_compiler.py grammar ext/test_grammar1

$ python test_compiler.py scanner <file with micro_lang>

• Where the <file with micro_lang> is the path to the file containing micro language.
• Example test files can be found in the ext dir.
• Prints out list of scanned tokens to stdout in a list.
