About this app
Source Code Preview is a Quick Look extension for source code files. It supports over 50 languages with beautiful syntax highlight. These languages are CSS, JavaScript, Swift, JSON, Python, Ruby, SQL, XML, YAML, Java, PHP, Rust, Go, Vue, Svelte, Sass, SCSS, Shell, Web Assembly, Kotlin, TOML, C, C++, C#, Dart, Perl, Lua, Visual Basic, Objective C, Zig, Clojure, Elixir, SRT(SubRip Subtitle file), and many more. We’re happy to support as many languages as possible. If you want some languages that we don’t support, email us hi@anybox.ltd. Source Code Preview also comes with enough settings to customize the appearance. You can change font, font size, and color themes. Thanks to the lazy load nature of the text view, Source Code Preview is able to handle huge lines of code in a breeze. Viewing large JSON files with Source Code Preview shouldn’t be a problem. * Due to macOS limitations, some files like TypeScript (.ts), HTML (.html) cannot be supported.
