Nixi is a programming language that combines:

• Nix-like functional syntax and purity
• Bash-like built-in functions and commands
• React.js-like GUI components
• CSS/QML styling capabilities
• Full HTML, CSS, and JavaScript support
• Language Server Protocol (LSP) support for all major editors

# One-line installation for any platform
curl -fsSL https://raw.githubusercontent.com/ijadux2/nixi/main/quick-install.sh | bash

Choose your operating system:

Nixi includes a complete Language Server Protocol (LSP) implementation providing:

• Intelligent code completion for keywords, HTML tags, and CSS properties
• Real-time error diagnostics as you type
• Hover documentation for language constructs
• Go to definition and find references
• Refactoring support with code actions
• Syntax highlighting across all major editors

• Neovim (with nvim-lspconfig)
• Cursor Editor (built-in LSP support)
• Helix (built-in LSP client)
• Emacs (with lsp-mode)
• VS Code (via extension)
• Kate/KDevelop (with LSP Client plugin)
• Kakoune (with kak-lsp)
• Sublime Text (with LSP plugin)
• And more...

# Install LSP server
cd lsp
npm install

# For specific editors, see:
# lsp/editor-configs/[editor-name]/README.md

# Example: Neovim setup
cp lsp/editor-configs/neovim/nixi-lsp.lua ~/.config/nvim/lua/
echo 'require("nixi-lsp")' >> ~/.config/nvim/init.lua

For detailed setup instructions for your favorite editor, see lsp-installation.html.

setx PATH "%PATH%;C:\path\to\nixi"

macOS/Linux (bash/zsh):

echo 'export PATH="$PATH:/path/to/nixi"' >> ~/.bashrc  # or ~/.zshrc
source ~/.bashrc  # or source ~/.zshrc

# Run a Nixi file directly
nixi examples/simple-gui.nixi

# Start interactive REPL
nixi

# Compile to JavaScript
nixi --compile examples/simple-gui.nixi > compiled.js

# Using npm scripts
npm run example:gui
npm run example:math
npm run example:dashboard
npm start              # Start REPL

# Run a GUI example
node src/cli.js examples/simple-gui.nixi
