Unmanaged Output

Now you can print unmanaged output above your inline applications. This means you can print stuff above your app that won't be cleared on the next render. It’s super useful for cases where you want to build an apt-like package manager.

Let’s Print

This release introduces two new Cmds that print output above your inline Bubble Tea program:

tea.Println("Hello, Bubble Tea")
tea.Printf("%s, %s", "Hello", "Bubble Tea")

Use it anytime you want to add log-type info to the terminal’s scrollback buffer, such as building your own package manager 📦. And keep in mind that these methods are no-op’s in altscreen mode.

Package Manager Demo

For details see the full example and the docs.

🤗 Thanks

@fiws has been bugging us to implement this forever and then @Adjective-Object swooped in and did it with style and grace! It’s been a great collaboration all around.

v0.21.0

Spawn Interactive Processes + More Keybindings

Finally! This update allows you to run blocking, interactive processes from Bubble Tea like vim, htop, curl, and even entire shells like fish. It also adds a bunch of new keybindings. Read on for more!

Let’s Exec

As we were saying, you can now spawn interactive processes in the terminal from Bubble Tea and resume Bubble Tea when they exit. For example, you could have your Bubble Tea program spawn vim to edit a file, or temporarily open a shell, like fish. Here’s what it looks like:

type editorFinishedMsg struct{ err error }

func openInVim(path string) tea.Cmd {
	c := exec.Command("vim", path)
	return tea.ExecProcess(c, func(err error) tea.Msg {
		return editorFinishedMsg{err}
	})
}

See the full example for details.

Keys Galore

Prior to this update, you couldn't bind to the functions keys. Isn't that crazy? @mrusme certainly thought so. With this update you can can now respond to F1 through F20, modifiers included.

And thanks to @bwahharharrr you can also now bind to arrow keys with the ctrl, shift and alt modifiers.

v0.20.0

Force Kill, Bugfixes, and Small Improvements

This is mostly a bugfix release, but there’s also a new feature where you can quit a Bubble Tea program immediately, skipping the final render, but still restoring the terminal state:

p := tea.NewProgram(model{})

go func() {
    if err := p.Start(); err != nil {
        fmt.Println("Oh no:", err)
        os.Exit(1)
    }
}()

// Later
p.Kill()

This can be useful in when to you need fine-grained management over a Bubble Tea program when using something like Wish. Special thanks to @aymanbagabas for implementing this swiftly and acutely.

Altscreen Repaints

This release fixes a small bug where views would render blank if the view’s return value didn’t change after toggling the altscreen.

🤗 Special thanks to @chris-miner for flagging this one.

It’s all about BSD

This release restores support for Dragonfly BSD and fixes a bug where general BSD builds would fail with Go 1.17. BSD users, let us know if you notice anything else is awry.

Welcome back, BSD

This update fixes a regression introduced in v0.16.0 that prevented Bubble Tea from building on BSD systems (excluding Darwin).

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())

v0.18.0

Hello, ANSI compressor!

The big news in this release is the integration of @muesli’s ANSI compressor from his new ANSI package. The compressor, which has been integrated into the renderer, automatically removes redundant ANSI sequences and, as such, it can be considered lossless. This should improve rendering speeds both locally and over the wire.

Other stuff

When quitting a Bubble Tea program from the outside you previously had to…

p.Send(tea.Quit())

…which works, but also feels a little silly. So now you can just…

p.Quit()

v0.17.0

Windows Stuff

This release adds mouse support in Windows! It also fixes a regression introduced in v0.16.0 where the arrow keys didn't work on Windows.

As a side effect to the above, cancelable reads have been disabled in Windows for now. This means applications running in Windows can not run multiple Programs in succession in the context of a single application, nor can user input be reliably read after a Program has exited until the Go application exits. This is temporary and a solution is in development.

Changelog

New

  • Mouse support in Windows

Fixed

  • Arrow keys work properly in Windows again

Changed

  • Input will no longer reliably close on Windows after exiting a Bubble Tea program as it did in v0.16.0. This will be addressed in a subsequent release.

v0.16.0

Cancelable Reads

This release implements a cancelable input reader which allows user input to be read after a Program has exited. This means that you can now run multiple Programs in succession in a single application as well as generally read user input in other after a Program has exited in the context of a single application.

In addition, all Goroutines are now gracefully terminated before Program.Start() returns, resulting in reliable behavior between subsequent Programs.

This update has been a major undertaking by @erikgeiser, who built specific implementations for Linux, BSD/macOS, and Windows as well as a general purpose implementation for other flavors of unix.
