gocui
A minimalist Go package for building console user interfaces with overlapping views and keybindings.
What is gocui?
GOCUI is a minimalist Go package for building console user interfaces (CUIs). It enables developers to create text-based applications with features like overlapping views, mouse support, and keybindings, solving the need for lightweight terminal-based interfaces.
Go developers building terminal applications, CLI tools, or text-based dashboards that require interactive user interfaces.
Developers choose GOCUI for its minimal API, concurrent-safe design, and comprehensive feature set including mouse support and colored text, making it a powerful yet simple alternative to more complex UI frameworks.
Overview
Minimalist Go package aimed at creating Console User Interfaces.
Use Cases
Best For
- Building terminal-based dashboards with interactive elements
- Creating CLI tools with complex user interfaces
- Developing text-based applications with overlapping windows
- Implementing keyboard-driven console applications
- Building reusable widgets for Go console interfaces
- Creating cross-platform terminal applications in Go
Not Ideal For
- Projects requiring graphical user interfaces with rich visuals or multimedia support
- Teams seeking drag-and-drop UI builders or pre-styled components for rapid development
- Applications that must run in web browsers or on mobile devices
- Large-scale projects needing extensive third-party widgets or plugin ecosystems
Pros & Cons
Pros
Offers a simple and straightforward interface, as highlighted in the philosophy, enabling rapid development of console UIs without unnecessary complexity.
The GUI can be modified at runtime safely, allowing for dynamic updates and interactions in multi-threaded Go applications without data races.
Enables creation of complex layouts with overlapping windows, similar to desktop applications, within the terminal, as shown in the screenshots with dynamic views.
Supports global and view-level keybindings along with mouse input, providing flexible user interaction for keyboard-driven and mouse-enabled interfaces.
Allows customization of text colors and includes a customizable edition mode with views implementing io.ReadWriter, enhancing visual distinction and user input management.
Cons
Building layouts requires setting exact coordinates for views, as seen in the example, which can be error-prone and tedious for dynamic or responsive interfaces.
Despite mentioning reusable widgets, there is no standard library of components like buttons or forms, forcing developers to build everything from scratch.
The README provides only basic examples, and advanced features like custom widgets or complex event handling require digging into source code or external resources.
Being text-based, it cannot render images or advanced graphical elements, restricting UI aesthetics to terminal-compatible text and colors.
