Textual Project Introduction
Textual is a Rapid Application Development (RAD) framework designed for Python developers looking to create sophisticated user interfaces. What sets Textual apart is its ability to create these applications not just for the desktop and web browsers, but also for terminal environments. Built on top of the popular Rich library, Textual offers an API inspired by modern web development.
Key Features
Textual applications shine in their interactivity and aesthetic appeal. They are capable of using up to 16.7 million colors and include features like mouse support and smooth, flicker-free animations. The framework includes a robust layout engine and re-usable components that make building feature-rich applications more accessible and efficient.
Compatibility and Requirements
Textual is cross-platform, making it suitable for Linux, macOS, and Windows systems. The only prerequisite for developers is a Python environment of version 3.8 or above.
Installation
Setting up Textual is straightforward. A simple command installs it via pip:
pip install textual
For those looking to develop applications with Textual, additional development tools can be installed with:
pip install textual-dev
Developers new to the framework can refer to the detailed documentation for guidance.
Demonstrations and Examples
Textual provides several built-in demonstrations to display its capabilities. By running the command python -m textual, developers can preview what Textual can achieve.
Various examples available in the Textual repository, such as code_browser.py with just 61 lines of code, highlight how concise yet powerful Textual can be. Other examples like calculator.py demonstrate how to implement grid layouts, while tutorials, such as the Stopwatch example, walk developers through app creation step-by-step.
Reference Commands
The textual command line tool includes sub-commands that allow users to preview styles and animations. For instance:
-
Easing Reference: Demonstrates animation parameters through movement and opacity.
textual easing -
Borders Reference: Explores the various border styles available in Textual.
textual borders -
Colors Reference: A walk-through of Textual's color design system.

Community and Support
For ongoing support, developers are encouraged to join the Textual community on Discord. This platform enables them to connect with other users, share insights, and collaborate on projects. Links to the Discord server can be found within the project documentation and online resources.
In summary, Textual is an innovative development framework that blends the worlds of terminal-based applications and modern web-style UIs, offering a rich palette of features for a wide range of use cases. It's an excellent choice for Python developers looking to create dynamic and visually appealing interfaces in a terminal environment.
