   ```

2. Add to your `~/.emacs` or `~/.emacs.d/init.el`:
   ```elisp
   (require 'baba-yaga-mode)
   ```

### Method 2: Using Package.el (Recommended)
1. Add to your `~/.emacs` or `~/.emacs.d/init.el`:
   ```elisp
   (add-to-list 'package-archives
                '("melpa" . "https://melpa.org/packages/") t)
   (package-initialize)
   ```

2. Install the package:
   ```elisp
   M-x package-install RET baba-yaga-mode RET
   ```

### Method 3: Using use-package
Add to your `~/.emacs` or `~/.emacs.d/init.el`:
```elisp
(use-package baba-yaga-mode
  :ensure t
  :mode ("\\.baba\\'" . baba-yaga-mode))
```

### Method 4: Using straight.el

```elisp
(straight-use-package 'baba-yaga-mode)
```

## Features
- Syntax highlighting for Baba Yaga language
- Automatic filetype detection for `.baba` files
- Indentation support
- Comment handling
- Highlighting for:
  - Keywords (when, then, is, with, etc.)
  - Types (Bool, Int, Float, String, etc.)
  - Operators (->, =>, +, -, etc.)
  - Functions and variables
  - Strings and numbers
  - Comments (// and /* */)
  - IO functions (io.out, io.in, etc.)

## Usage
Open any `.baba` file and Emacs should automatically detect the language and apply syntax highlighting.

## Customization
You can customize the mode by adding to your `~/.emacs` or `~/.emacs.d/init.el`:

```elisp
;; Customize indentation width
(setq baba-yaga-indent-width 4)

;; Customize colors (if using a theme)
(custom-set-faces
 '(font-lock-keyword-face ((t (:foreground "blue"))))
 '(font-lock-type-face ((t (:foreground "green"))))
 '(font-lock-operator-face ((t (:foreground "red")))))
```

## Key Bindings
- `RET` - Insert newline and indent

## File Structure
```
dev/emacs/
├── baba-yaga-mode.el     # Major mode definition
└── README.md             # This file
```

## Building from Source
If you want to install from the source files:

1. Clone the repository
2. Add the `dev/emacs` directory to your load path:
   ```elisp
   (add-to-list 'load-path "~/path/to/baba-yaga/dev/emacs")
   (require 'baba-yaga-mode)
   ```

## Troubleshooting
If syntax highlighting doesn't work:

1. Check that the mode is loaded: `M-x describe-mode`
2. Verify filetype detection: `C-h v major-mode`
3. Force mode activation: `M-x baba-yaga-mode`
4. Check for errors: `M-x view-lossage`
