ESPCompose Language Support

Syntax highlighting for inline C++ inside ESPCompose lambda tagged template literals.

Features

• C++ syntax highlighting inside lambda`...` tagged templates in .ts and .tsx files
• Proper handling of ${...} template substitutions (highlighted as TypeScript)
• Recognition of ESPHome APIs (id(), ESP_LOG*), LVGL functions, C++ keywords, types, operators, strings, comments, and numeric literals

Usage

Install the extension and open any ESPCompose project. Inline C++ in lambda tagged templates is highlighted automatically:

import { lambda, useRef } from '@espcompose/core';

<binary_sensor
  platform="gpio" pin={4} name="Button"
  onPress={async () => {
    lambda`id(${lightRef}).turn_on().set_brightness(0.75).perform();`;
  }}
/>

Requirements

• VS Code 1.75+
• Works alongside any TypeScript/TSX language support
