Quick Look already supports multiple file types. But there ist more – especially for software development. Here are some plugins that make Quick Look even better.

Note: some of the plugins might not work instantly after brew install ... when you are on macOS Catalina or later. In this case, it is possible to download the plugin manually and copy the .qlgenerator file to ~/Library/QuickLook. This requires to run qlmanage -r (or a system restart) to enable the plugin.
