BeatSaber Markup Language (BSML) is a specialized XML-based markup language used primarily within the modding community of the virtual reality rhythm game, Beat Saber. Developed to simplify the creation of custom user interfaces for game modifications, BSML allows developers to define complex UI layouts, buttons, sliders, and text fields using a declarative syntax similar to HTML or XAML. Instead of writing verbose C# code to manually instantiate and position Unity UI elements, modders can write BSML files that are parsed at runtime to generate the interface. This format is heavily integrated with the BeatSaberMarkupLanguage library, which handles the binding between the XML tags and the underlying Unity components. It supports features like layout groups, scrolling views, and event handling through C# controllers. Because it is essentially a text-based XML format, it is easily readable and editable using standard text editors, making it an essential tool for anyone developing plugins or custom menus for the Beat Saber VR experience. It streamlines the development process by separating the visual presentation from the underlying logic of the mod.
