Typedef Documentation

flagStrs

typedef tnarr<nStr> by::flagStrs

Command-line interface for frontend language system.

Core class of the frontend module. Uses interpreter from the core module to parse, verify, and evaluate code, coordinating appropriate classes for these processes. Rather than implementing algorithms itself, cli orchestrates well-designed classes.

Receives user-entered arguments to the CLI program as parameters and parses them to perform additional commands. See the flags folder for details.

Core algorithm

When user calls eval() with flagArgs parameter, execution proceeds as follows:

1. Create interpreter, errReport, starter objects
2. Set flags on interpreter and starter (refers to worker flags, different from cli's flag. See worker for details)
3. Parse flagArgs to perform preliminary work (executed by calling take() on flag object)
4. Execute interpreter
5. Check interpretation results. If issues exist, output results and terminate
6. If no issues, put verified AST into starter and execute
7. Return starter's result
