HenryKovalevsky/Thuja

This system is a terminal user interface (TUI) framework for F\# that provides a declarative API for building interactive console applications. It supports complex layouts, text rendering, and keyboard input handling, with an ANSI-based backend for visual styling. The codebase primarily consists of the core library and several sample applications demonstrating features like tables, menus, and image viewing.

A new sample program in sample/Table demonstrates a static table view displaying Kubernetes pod information (namespace, name, status, etc.) using the Thuja framework's table and panel elements.

Thuja now includes a new ANSI-based backend that renders UI elements to the terminal using escape codes for colors and styles, replacing previous dependencies. The core module defines the fundamental data structures for the UI, including Style, Color, KeyInput, and the ViewTree, while the Program module provides the main application loop for handling model updates, view rendering, and keyboard input. Additionally, the Styles module offers utilities for defining colors (including hex and RGB), text attributes, and various border styles for terminal-based interfaces.

The \src/Thuja/Elements\ module now provides a comprehensive set of UI components for building terminal interfaces. This includes layout primitives (\Layout.fs\) for columns, rows, and grids using absolute or fractional sizing, and a \Region\ element supporting margins and alignment. Visual elements such as \Panel\ (with customizable border styles and colors), \Rule\ (horizontal/vertical lines), and \Table\ (with headers, data, cell styling, and borders) are available. Text handling is enhanced via the \Text\ element, which supports color, background, attributes, overflow modes (wrap, clip, ellipsis), and horizontal/vertical alignment. Helper utilities in \Helpers.fs\ provide text truncation and word-wrapping logic, while \List\ and \Raw\ elements allow for simple item lists and custom rendering.

A new sample application (sample/SimpleMenu) demonstrates a split-panel UI using the Thuja framework. The interface features a list of text items (including multi-byte characters) in the left panel and instructional text in the right panel. Users can navigate the list using Up/Down arrow keys, and the text elements support overflow wrapping. The sample also implements basic key bindings for exiting the application via Ctrl+C or 'q'.

Added a new sample application in sample/ImageViewer that displays images in the terminal using the chafa tool for ANSI/sixel rendering. The app features a sortable file list menu, custom key bindings (j/k for navigation, s to sort, q/c to quit), and demonstrates integrating external CLI tools within the Thuja framework.

The core terminal user interface library (Thuja) and its accompanying sample application have been removed from the codebase. This deletion eliminates the Elmish-style architecture that previously handled model/view/update cycles, including the DSL for defining UI layouts (columns, rows, panels, lists, text, and raw output), the layout engine, and the main program loop responsible for rendering and keyboard input processing.

The Calendar sample application now renders its schedule data in a table format that includes visible borders and center-aligned text, providing a clearer visual structure for the weekly task view.

The Thuja F\# terminal UI library has updated its public API and documentation. The program entry point now uses \Program.make\ instead of \Program.run\, requiring explicit configuration via \Program.withKeyBindings\ for input handling. The view API has changed: layout columns now accept \Fraction\ values, and list/text components take configuration lists as their first argument. Keyboard input is now handled via structured events (\Up\, \Down\, \Char\) rather than raw string matching, and the exit command is accessed via \Program.exit()\. The README also reflects these changes and points to a new Wiki for documentation.

(repo-wide) · high confidence

The project has been reorganized to separate the core library from sample applications. The main library is now located in src/Thuja/Thuja.fsproj, while sample applications (Clock, SimpleMenu, Table, Calendar, ImageViewer) have been moved to the sample/ directory. All projects now target .NET 8.0. The Calendar sample has been refactored to reference the core library as a project reference instead of using the external Tutu package, and the ImageViewer sample has been renamed and updated to reference the new library location.
