## Introduction
Lite-XL is a fork of the lite editor that adds multi-language support, improved rendering, and a richer plugin ecosystem while preserving the original vision of a lightweight, hackable text editor. It provides a responsive editing experience using under 30 MB of RAM.

## What Lite-XL Does
- Provides syntax highlighting for 100+ programming languages
- Supports multi-cursor editing and regex-based find and replace
- Renders text with sub-pixel antialiasing via FreeType and SDL2
- Offers a command palette for quick access to all editor actions
- Extensible through Lua plugins with a simple, documented API

## Architecture Overview
The editor core is written in C for performance (rendering, file I/O, event handling) while the entire UI and editor logic is implemented in Lua. This split gives plugin authors full control over behavior without needing to recompile. SDL2 handles cross-platform window management and GPU-accelerated text rendering.

## Self-Hosting & Configuration
- Download portable binaries for Linux, macOS, and Windows
- Configuration is a Lua file at ~/.config/lite-xl/init.lua
- Install plugins by dropping Lua files into the plugins directory
- Use the built-in plugin manager (lpm) to browse and install community plugins
- Customize themes by editing color tables in Lua

## Key Features
- Startup in under 100 milliseconds on typical hardware
- Memory usage under 30 MB for normal editing sessions
- Native support for high-DPI displays and fractional scaling
- Split view editing with draggable pane borders
- IME support for CJK and other input methods

## Comparison with Similar Tools
- **VS Code** — Feature-rich but requires 500+ MB RAM and Electron
- **Sublime Text** — Fast and polished but proprietary
- **Micro** — Terminal-based editor, no GUI
- **Notepad++** — Windows-only with a dated interface
- **Kakoune** — Modal terminal editor with different interaction paradigm

## FAQ
**Q: Does Lite-XL support LSP (Language Server Protocol)?**
A: Yes, via the lsp plugin which provides autocomplete, diagnostics, and go-to-definition backed by language servers.

**Q: Can I use it as a full IDE?**
A: With plugins for LSP, terminal integration, git, and file tree, it can approximate an IDE while staying lightweight.

**Q: How does it compare to the original lite editor?**
A: Lite-XL adds multi-language support, improved font rendering, high-DPI support, a plugin manager, and many bug fixes over the original.

**Q: Is there a plugin ecosystem?**
A: Yes. The community maintains hundreds of plugins covering LSP, linting, formatting, themes, and language support, installable via the lpm package manager.
