Instance Method Details

#component_installed?(name) ⇒ Boolean

A ruby_ui component is considered installed once its package directory (or single-file component) exists under app/components/ruby_ui/. Guarding on this is essential: ‘ruby_ui:component` copies files WITHOUT –force, so re-installing a present component prompts interactively — which would hang a non-interactive subprocess.

Returns:

  • (Boolean)
