Thanks for sharing! This is awesome because it's so much easier to embed than Python Prompt Toolkit, which IMO is the state of the art for building terminal-based interfaces. RxTerm is exciting though because it isn't constrained performance-wise, is MIT licensed and it compiles to native code and static binaries and overall lends a simpler packaging and distribution experience.
