Bubbles

Some components for Bubble Tea applications. These components are used in production in Glow, Charm and many other applications.

Spinner

A spinner, useful for indicating that some kind an operation is happening. There are a couple default ones, but you can also pass your own ”frames.”

• Example code, basic spinner
• Example code, various spinners

Text Input

A text input field, akin to an <input type="text"> in HTML. Supports unicode, pasting, in-place scrolling when the value exceeds the width of the element and the common, and many customization options.

• Example code, one field
• Example code, many fields

Text Area

A text area field, akin to an <textarea /> in HTML. Allows for input that spans multiple lines. Supports unicode, pasting, vertical scrolling when the value exceeds the width and height of the element, and many customization options.

• Example code, chat input
• Example code, story time input

Table

A component for displaying and navigating tabular data (columns and rows). Supports vertical scrolling and many customization options.

• Example code, countries and populations

Progress

A simple, customizable progress meter, with optional animation via Harmonica. Supports solid and gradient fills. The empty and filled runes can be set to whatever you'd like. The percentage readout is customizable and can also be omitted entirely.

• Animated example
• Static example

Paginator

A component for handling pagination logic and optionally drawing pagination UI. Supports "dot-style" pagination (similar to what you might see on iOS) and numeric page numbering, but you could also just use this component for the logic and visualize pagination however you like.

• Example code

Viewport

A viewport for vertically scrolling content. Optionally includes standard pager keybindings and mouse wheel support. A high performance mode is available for applications which make use of the alternate screen buffer.

• Example code

This component is well complemented with Reflow for ANSI-aware indenting and text wrapping.

List

A customizable, batteries-included component for browsing a set of items. Features pagination, fuzzy filtering, auto-generated help, an activity spinner, and status messages, all of which can be enabled and disabled as needed. Extrapolated from Glow.

• Example code, default list
• Example code, simple list
• Example code, all features

Timer

A simple, flexible component for counting down. The update frequency and output can be customized as you like.

• Example code

Stopwatch

A simple, flexible component for counting up. The update frequency and output can be customized as you see fit.

• Example code

Help

A customizable horizontal mini help view that automatically generates itself from your keybindings. It features single and multi-line modes, which the user can optionally toggle between. It will truncate gracefully if the terminal is too wide for the content.

• Example code

Key

A non-visual component for managing keybindings. It’s useful for allowing users to remap keybindings as well as generating help views corresponding to your keybindings.

type KeyMap struct {
    Up key.Binding
    Down key.Binding
}

var DefaultKeyMap = KeyMap{
    Up: key.NewBinding(
        key.WithKeys("k", "up"),        // actual keybindings
        key.WithHelp("↑/k", "move up"), // corresponding help text
    ),
    Down: key.NewBinding(
        key.WithKeys("j", "down"),
        key.WithHelp("↓/j", "move down"),
    ),
}

func (m Model) Update(msg tea.Msg) (tea.Model, tea.Cmd) {
    switch msg := msg.(type) {
    case tea.KeyMsg:
        switch {
        case key.Matches(msg, DefaultKeyMap.Up):
            // The user pressed up
        case key.Matches(msg, DefaultKeyMap.Down):
            // The user pressed down
        }
    }
    return m, nil
}
