Class Method Details

.ansi_supported?(output, on_windows: Gem.win_platform?, env: ENV, api: nil) ⇒ Boolean

Redirected output remains ANSI-capable; interactive output requires Windows Terminal and VT support. Fiddle failures fall back to plain text, while unrelated errors propagate.

Returns:

  • (Boolean)
