A script to identify crashes during the transpilation and reverse transpilation processes. As per @SaadBazaz 's guidance, I am starting with a barebone Bash script to understand the CLI behavior moving to a full pytest suite.

The script currently:

  • Validates Native to English transpilation.
  • Validates English to Native transpilation.
  • Captures and logs detailed Python tracebacks into test_failures.log for debugging.

Issues and observations:

  • The requirements.txt specifies PyYAML==5.4.1, which fails to build on Python 3.13 . Upgrading to the latest PyYAML resolves this.
  • After running the script, the transpiler "crashes" due to the following error:
Traceback (most recent call last):
  File "F:\UniversalPython\UniversalPython\universalpython\universalpython.py", line 210, in <module>
    sys.exit(main())

@shahrukhfu - Can you try a language other than German, for the test?

@SaadBazaz I have tested with a different language; french, and am getting the same error:

KeyError: 'default'

@shahrukhfu -
What do you think this error means? Can you explain?

It seems like you AI-generated all this but are not debugging it properly.

  1. Why did you write default?
  2. If you know why you did, what did you expect would happen?

@SaadBazaz I have fixed the error, it was due to wrong initialization of the LANGUAGE variable in the bash script. There is no variable default in my script, it is an existing logic in universalpython.py, and the error occured because the code tried to access a dictionary which didn't exist (instead of "german" or "french" I was supposed to write the language code "de", "fr").
