Features

Syntax highlighting for embedded languages inside Nix multi-line strings ('' ... '').

Usage

Pattern 1: Short form (inside string)

Place # lang on its own line inside the string:

script = ''
  # shell
  echo "Hello, world!"
  ls -la
'';

Pattern 2: Explicit form with # syntax: (inside string)

For clarity, use # syntax: lang:

script = ''
  # syntax: python
  def greet(name):
      print(f"Hello, {name}!")
  greet("World")
'';

Pattern 3: Typescript / C-style comment // syntax: (inside string)

For languages where // is a comment:

code = ''
  // syntax: javascript
  const greeting = "Hello!";
  console.log(greeting);
'';

Pattern 4: Comment before string (for JSON, etc.)

For languages without comments (like JSON), place the marker BEFORE the string as a Nix comment:

# syntax: json
configData = ''
  {
    "name": "example",
    "version": "1.0.0"
  }
'';
