__main__

naas_abi_core.utils.onto2py.__main__

What it is

• The module entry point for running onto2py via python -m ....
• Converts a Turtle (.ttl) file into generated Python code and writes it to an output file.

Public API

• main()
  • CLI-style function that:
    • Reads <ttl_file> and <output_file> from sys.argv.
    • Calls onto2py(ttl_file) to generate Python source code.
    • Writes the generated code to <output_file>.
    • Exits with status 1 on incorrect usage or conversion/write errors.

Configuration/Dependencies

• Standard library:
  • sys for CLI argument handling and exit codes.
• Internal dependency:
  • from .onto2py import onto2py (must be available and callable as onto2py(ttl_file)).

Usage

Run as a module (expects two arguments: input TTL file and output Python file):

python -m naas_abi_core.utils.onto2py input.ttl output.py

Programmatic invocation (uses sys.argv):

from naas_abi_core.utils.onto2py.__main__ import main
 
# Ensure sys.argv is set appropriately before calling main()
main()

Caveats

• Requires at least two CLI arguments; otherwise prints usage and exits with code 1.
• Any exception during conversion or file writing is caught, printed, and causes exit code 1.
• The success/error messages include Unicode symbols (✅ / ❌).
