Red Sea Markup Language

Breaking API and Language Changes

This documentation refers to RSML v2.0.0+. RSML has changed a lot from v1.x.x (a.k.a. Legacy RSML) to v2.0.0.

Red Sea Markup Language is the powerful and robust fork of MF's CrossRoad Solution, a language designed to dynamically interpret different logic paths based on the local host OS and CPU architecture.

RSML (short for Red Sea Markup Language) can currently be used directly in C# and Python, as well as in its own CLI. We are currently working in the native C ABI as well, which will let you use RSML in whatever programming language you like (as long as it allows for C interop).

To further enhance your experience with RSML, we offer a list of useful links in this journey through our logic-heavy markup language.

  • Official GitHub Repository
