Open Policy Agent's rego

[ralgozino]

Motivation

We're using Prism in our opensource project Gatekeeper Policy Agent to show rego code snippets and yaml/json files. We are using as a workaround the "ruby" highlighter that is somewhat similar to rego, but sadly is not good enough.

Language
OPA is purpose built for reasoning about information represented in structured documents. The data that your service and its users publish can be inspected and transformed using OPA’s native query language Rego.

What is Rego?
Rego was inspired by Datalog, which is a well understood, decades old query language. Rego extends Datalog to support structured document models such as JSON.

Rego queries are assertions on data stored in OPA. These queries can be used to define policies that enumerate instances of data that violate the expected state of the system.

There's also a VSCode plugin that adds syntax highlighting, can be useful as starting point:

Let me know if you need anything else or how can I help to add support for this language 🙂
Thank you!
