Roto

Roto is a full programming language that is fast, safe and easy to use. It is made to integrate especially well with Rotonda, so that writing filters is as simple as possible.

Used by Rotonda, the composable, programmable routing BGP engine.

Scripts are compiled to machine code by Rotonda before they are executed. This means that they run quickly and introduce minimal latency into your system.

A strong and static type system ensures that every expression must be of a well defined, unambiguous type. Roto scripts therefore cannot crash Rotonda and can be used safely. This does not mean that the user has to specify types everywhere, most types can be inferred by the Roto compiler. When the compiler detects a mistake in your script, it will emit a friendly message.

Roto has no facilities to create loops. The reason for this is that scripts need to run only for a short time and should not slow down the application.
