Installation

1. Open Visual Studio Code
2. Go to Extensions (Ctrl+Shift+X)
3. Search for "EDL Language Support"
4. Click Install

Usage

1. Create a new file with .edl extension
2. Start writing EDL code with full syntax highlighting
3. Use Ctrl+Space for IntelliSense suggestions
4. Hover over keywords and functions for documentation
5. View real-time linting feedback in the Problems panel

Configuration

Access settings via File > Preferences > Settings, then search for "EDL":

```json { "edl.linting.enabled": true, "edl.intellisense.enabled": true, "edl.theme.customColors": { "keyword": "#ff0080", "function": "#8080ff" } } ```

Commands

• EDL: Validate File - Manually validate the current EDL file

Example EDL Code

```edl // Define an event event user_login { user_id: string timestamp: int session_token: string }

// Create a state machine state authentication { idle -> authenticating on user_login authenticating -> authenticated on success authenticating -> failed on error failed -> idle on retry }

// Event handler handler handle_login(event: user_login) { log("User login attempt:", event.user_id)

if (validate_credentials(event)) {
    emit(authentication_success, event)
    transition_to(authenticated)
} else {
    emit(authentication_failed, event)
    transition_to(failed)
}

}

// Listen for events listen(user_login, handle_login)

// Schedule cleanup schedule(cleanup_sessions, delay: 3600) // 1 hour
