The grammar for jrsonnet

[indegro]

Hello.
My name is Denys and I am a developer of the Jsonnet Pro plugin for JetBrains-based IDEs. I am gathering implementations for the Jsonnet language available on the market. I see that the Rust implementation has additional features.

Is there a file with the grammar that describes these additions to the language? I want to experiment with it and add it to the parser used inside the plugin.

I appreciate any help you can provide.

Best regards,
Denys Dushyn
