Misleading error message when flag name has an underscore

[RichardBowenGM]

Example code:

from cyclopts import App
app = App()

@app.command
def foo(test_flag: bool):
  print("x" if test_flag else "y")

app()

Executing with --test-flag:

$python test.py foo --test_flag
╭─ Error ─────────────────────────────────────────────────────────────────╮
│ Unknown option: "--test-flag".                                          │
╰─────────────────────────────────────────────────────────────────────────╯

The error message seems incorrect, because --test-flag is right and is a known option. Ideally cyclopts should say Unknown option: --test_flag, or maybe test-flag and test_flag should be synonyms.

Version info: cyclopts 2.3.1, python 3.9.18.

I'll be trying to pipe through what the CLI-provided token was so that help/error messages can be a bit more specific.

This has been addressed in the newly released v2.4.0
