Recursive Image Grid Display for Kitty Terminal

Project Proposal

Objective

Implement a feature for Kitty terminal that allows recursive display of images in a responsive grid layout, adapting to window size changes and handling images with different aspect ratios.

Key Features

Recursive directory scanning for images
Dynamic grid layout calculation
Efficient image resizing and caching
Responsive handling of window size changes
Keyboard navigation for image browsing
Integration with Kitty's graphics protocol

Implementation Strategy

1. Image Discovery and Metadata Extraction

Implement a recursive directory scanner in icat/discovery.go
Use Go's image package to extract basic metadata (dimensions, format)
Utilize goroutines for concurrent processing of multiple images

2. Grid Layout Calculation

Develop an algorithm in icat/layout.go to calculate optimal grid dimensions
Consider terminal dimensions and number of images
Implement adaptive sizing to maintain aspect ratios

3. Image Resizing and Caching

Use the github.com/disintegration/imaging library for efficient resizing
Implement a simple in-memory cache in utils/cache.go
Consider implementing a worker pool for parallel processing

4. Window Size Handling

Utilize Kitty's existing window size detection mechanism
Implement a debounce function to limit layout recalculations
Update grid layout and re-render images on size changes

5. Image Rendering

Extend the existing icat kitten in icat/render.go
Use Kitty's graphics protocol for efficient image placement
Implement batch rendering for improved performance

6. Keyboard Navigation

Implement keyboard event handling in icat/navigation.go
Use arrow keys for navigation and 'q' for quitting
Highlight the currently selected image

Project Structure

File Descriptions

main.go: This is the entry point of the icat kitten. It contains the main logic and orchestrates the overall functionality.
discovery.go: Handles recursive directory scanning and image metadata extraction. It identifies image files and gathers basic information like dimensions and format.
layout.go: Implements the grid layout calculation algorithm. It determines the optimal arrangement of images based on the terminal window size and the number of images.
render.go: Manages the rendering of images using Kitty's graphics protocol. It handles the placement and display of images in the calculated grid layout.
navigation.go: Implements keyboard navigation functionality, allowing users to browse through the displayed images using arrow keys or other defined shortcuts.
cache.go: Located in the utils folder, this file implements image caching mechanisms to improve performance by storing and retrieving processed images.

This structure organizes the project into logical components, separating concerns and making the codebase more maintainable. Each file focuses on a specific aspect of the functionality, allowing for easier development, testing, and future enhancements.

This README provides a technical overview of the project, key features, and a basic implementation plan. The reference code snippets demonstrate how we can approach the main components of the project using Go. cd
