What is Highlightr?
Highlightr is an iOS and macOS syntax highlighter built with Swift that uses highlight.js to convert plain code strings into formatted NSAttributedString objects. It supports 185 programming languages and 89 visual styles, enabling developers to add syntax highlighting to text editors, code viewers, or any app displaying code. The project solves the need for a ready-to-use, multi-language syntax highlighter within Apple's ecosystem without requiring native parsing implementations.
iOS and macOS developers building applications that display or edit code, such as code editors, documentation tools, educational apps, or developer utilities. It's particularly useful for those who need broad language support and customizable themes without implementing highlighting from scratch.
Developers choose Highlightr because it leverages the widely-used highlight.js library, providing extensive language support and theme variety out of the box. Its integration with Swift and Apple's JavaScriptCore ensures decent performance for real-time editing, while its simple API makes it easy to add syntax highlighting to existing projects.
