TypeScript Template Engine VSCode Extension

This VSCode extension provides syntax highlighting for template literals in TypeScript (.ts) and JavaScript (.js) files. It allows you to use TypeScript as a template engine through template literals directly in your code files without requiring any special file extensions.

Features

• Syntax highlighting for 40+ programming languages and file formats within template literals
• Works directly in TypeScript (.ts) and JavaScript (.js) files
• No special file extensions needed - just use the tag functions in your code
• Support for custom language extensions via the ext function

Usage

Simply use the appropriate tag function for your template literals:

import { html, css, js, sql, json, md } from "ts-tmpl-engine";

// HTML with syntax highlighting
const template = html`
  <div class="container">
    <h1>${title}</h1>
    <p>${content}</p>
  </div>
`;

// CSS with syntax highlighting
const styles = css`
  .container {
    max-width: 800px;
    margin: 0 auto;
  }
`;

// JavaScript with syntax highlighting
const script = js`
  function handleClick() {
    console.log('Button clicked!');
  }
`;

// SQL with syntax highlighting
const query = sql`
  SELECT * FROM users WHERE id = ${userId}
`;

// JSON with syntax highlighting
const data = json`
  {
    "name": "John Doe",
    "age": 30,
    "email": "${email}"
  }
`;

// Markdown with syntax highlighting
const documentation = md`

Using Custom Extensions

You can use any file extension with the ext function:

import { ext } from "ts-tmpl-engine";

// Use a custom extension
const svelte = ext("svelte");
const template = svelte`
  <script>
    let count = 0;
    
    function increment() {
      count += 1;
    }
  </script>

  <button on:click={increment}>
    Clicked {count} {count === 1 ? 'time' : 'times'}
  </button>
`;

How It Works

This extension uses VSCode's grammar injection to provide syntax highlighting for template literals. It recognizes the tag functions from the ts-tmpl-engine library and applies the appropriate syntax highlighting based on the tag name.
