About
Made by experienced macOS developer, Source Code Preview is a Quick Look extension for macOS.
After installation, you can quick look source code files of over 50+ languages with beautiful syntax highlighting and line numbers.
The app comes with over 10 color themes. You can also choose which monospaced font you want to see in the quick look window.
You can download the app at Mac App Store for USD$5.99.
Disclaimer: Most of the code of the app is still written by human. AI is used only in converting some color themes and writing some TextMate grammars for a few languages without existing grammar files.
