This issue exists in the latest version

• I am using the latest version

Current Behavior

With the latest version 0.10.3 there is a new bug, where certain queries cause an unexpected CLI error message.

For example:

• The following cmd command:

  kipper run -s "x"

  returns:

  ERROR Compilation error - Traceback:
  File 'anonymous-script', line 1, col 1:
    x
  
  SyntaxError: Missing ';' at '<EOF>'.
  FATAL Failed to compile 'anonymous-script'.
   »   Unexpected CLI Error: Missing ';' at '<EOF>'.
   »   Try this: Ensure no invalid types or data were passed to module functions or classes. Otherwise report the issue on https://github.com/Kipper-Lang/Kipper. Help us improve Kipper!

Expected Behavior

The failure of the command should not counted as an "Unexpected CLI Error", as it is defined behaviour.

Steps To Reproduce

1. Install version 0.10.3
2. Call up CLI with any invalid flag or try to compile/run a syntax-invalid Kipper script.

Environment

• Kipper: 0.10.3
• Environment: v18.16.1
• Operating System: Windows 11

Fixed by #502 and will be released in the next release v0.10.4.

[Luna-Klatzer]

To be implemented as well for 0.11.0-alpha.1 (#510).

[Luna-Klatzer]

Uncovered edge-case discovered in 0.10.4:

Input:

kipper run --target=kip --string-code=";"

Result:

 »   Unexpected CLI Error: Expected --target=kip to be one of: js, ts
 »   See more help with --help
 »   Try this: Ensure no invalid types or data were passed to module functions or classes. Otherwise report the issue
 »   on https://github.com/Kipper-Lang/Kipper. Help us improve Kipper!

Cause:

The decorator prettifiedErrors<TProto extends Command>() doesn't treat CLIError from @oclif/errors as a standard CLI error, which is wrong.

Going to be fixed with PR #510 for next release 0.11.0-alpha.1.

[Luna-Klatzer]

Finished issue with merge of #510.
