Ondine is a Rust/WASM port of Pele for rendering #Mermaid graphs in a monochromatic fashion. When I discovered it, I immediately found it beautiful, but I didn't want to use #npm just to generate some SVGs.
So I wrapped their compiler and ported the #ASCII formatter into a pure #Rust CLI. No #Node or WASM at runtime, so it is also smaller and faster: ideal for a quick #cargo or #Nix install.
If you need quick #diagrams, enjoy. Thanks to the Pele and Ondine folks.
