## What it is
Splash is a fast, lightweight Swift syntax highlighter that can be used as a Swift Package Manager library or via built-in command line tools. It generates syntax-highlighted HTML for blog posts, images from Swift code strings, and supports integration with static site generators like Publish and Jekyll.

## Use cases
- highlight swift code in blog posts
- generate html from swift code snippets
- convert swift code to a syntax highlighted image
- add swift syntax highlighting to a static site generator
- build custom developer tools that render swift code
- style code samples with custom css classes

## When to choose
- you need to highlight Swift code specifically in HTML, images, or custom tools
- you use Publish or Jekyll and want integrated Swift highlighting
- you want a lightweight, fast highlighter without hardcoded styling

## When to avoid
- you need syntax highlighting for languages other than Swift
- you need a JavaScript-based client-side highlighter for a dynamic website
- you need highlighting of very recent Swift syntax versions
