Huh is an open-source Go library by Charmbracelet for building interactive terminal forms and prompts. It provides a rich set of form components — text inputs, selects, multi-selects, text areas, and confirmation dialogs — that can be composed into multi-page forms with validation, theming, and first-class accessibility support.
What It Does
Huh lets developers create sophisticated terminal-based forms with minimal code. Forms are composed of groups (pages) containing fields. Each field type handles user interaction, validation, and rendering automatically. The library supports both standalone usage and integration with Bubble Tea applications.
Key Features
Rich Field Types: Input (single-line text), Text (multi-line), Select (single choice from list), MultiSelect (multiple choices with optional limit), and Confirm (yes/no). Each field supports titles, descriptions, placeholders, and custom validation functions.
Multi-Page Forms: Group fields into logical pages that the user navigates through sequentially. Each group can contain any combination of field types.
Built-in Validation: Attach validation functions to any field. The form highlights invalid fields with error messages and prevents submission until all validations pass.
Dynamic Forms: Forms can change based on previous input — show or hide fields, modify options, or branch to different groups based on user selections.
Theming and Styling: Comes with multiple built-in themes (Charm, Dracula, Catppuccin, Base 16) and supports custom themes via Lip Gloss styles. Every visual aspect is configurable.
Accessibility: Includes a first-class accessible mode designed for screen readers, ensuring terminal forms work for all users.
Standalone Shorthand: Individual fields can be run directly without wrapping them in a form, making quick single-prompt interactions trivial.
How Agents Use It
AI coding agents building Go CLI tools that require user input can use Huh to generate interactive configuration wizards, setup flows, or data collection prompts. Agents working on Go TUI applications can integrate Huh forms directly into Bubble Tea programs. The library is particularly useful for scaffolding tools, project initializers, and any CLI that needs structured user input with validation.
Installation
go get charm.land/huh/v2Integration Points
Huh integrates with Bubble Tea for embedding forms in TUI applications, uses Lip Gloss for styling, and works with the Glamour markdown renderer for rich form descriptions. It is part of the Charmbracelet ecosystem alongside Gum (shell script forms), Bubble Tea (TUI framework), and other terminal tools.
