v0.19.0

Final Model Access

This release features Program.StartReturningModel, a handy alternative start method for returning the final Model after a Program exits. This makes it easy to access data collected in a Bubble Tea program while still working in an immutable fashion.

Here’s an example illustrating how it works:

type MyModel struct {
	Name         string
	FaveCatColor string
}

p := tea.NewProgram(MyModel{})

// Return the final model when we're done
finalModel, err := p.StartReturningModel()
if err != nil {
	fmt.Println("Uh oh", err)
	os.Exit(1)
}

// The final model is a generalized tea.Model, so be sure to assert it into
// your actual model type.
if m, ok := finalModel.(MyModel); ok {
	fmt.Printf("Hello, %s. I have a %s kitty for you.\n", m.Name, m.FaveCatColor)
}

🤗 A big thanks to @Raphexion for both conceptualizing and executing this feature.

ANSI Compression, Now Opt-In

We’ve also made the ANSI compressor opt-in by default as we noticed that it was incurring a larger performance hit than we’d like in some cases. To enable the ANSI compressor just use the WithANSICompressor program option:

tea.NewProgram(model, tea.WithANSICompressor())
