Bubble Tea

The fun, functional and stateful way to build terminal apps. A Go framework based on The Elm Architecture. Bubble Tea is well-suited for simple and complex terminal applications, either inline, full-window, or a mix of both.

Bubble Tea is in use in production and includes a number of features and performance optimizations we’ve added along the way. Among those is a standard framerate-based renderer, a renderer for high-performance scrollable regions which works alongside the main renderer, and mouse support.

Getting Started

We recommend starting with the basics tutorial followed by the commands tutorial, both of which should give you a good understanding of how things work.

There are a bunch of examples, too!

Components

For a bunch of basic user interface components check out Bubbles, the official Bubble Tea component library.

  

Debugging

Debugging with Delve

Since Bubble Tea apps assume control of stdin and stdout, you’ll need to run delve in headless mode and then connect to it:

# Start the debugger
$ dlv debug --headless .
API server listening at: 127.0.0.1:34241

# Connect to it from another terminal
$ dlv connect 127.0.0.1:34241

Note that the default port used will vary on your system and per run, so actually watch out what address the first dlv run tells you to connect to.

Logging Stuff

You can log to a debug file to print debug Bubble Tea applications. To do so, include something like…

if len(os.Getenv("DEBUG")) > 0 {
	f, err := tea.LogToFile("debug.log", "debug")
	if err != nil {
		fmt.Println("fatal:", err)
		os.Exit(1)
	}
	defer f.Close()
}

…before you start your Bubble Tea program. To see what’s printed in real time, run tail -f debug.log while you run your program in another window.
