Description

I want to write Cedar Policy Language in Monaco-editor implemented in my web app. I've managed to define 'cedar' as a custom language for me by providing tokens and suggestions. But when it comes to error handling by setting markers in the editor, it is tough to handle user-written code in editor by checking every nested bracket. There is a vs-code extension for Cedar language. Can we use that extension directly in the Monaco editor?

Please let me know how I manage to handle error handling like vs-code in my custom-defined language for each and every small rule of the nested bracket without defining it from scratch.

Monaco Editor Playground Code

permit (
principal == PhotoApp::User::"alice",
action == PhotoApp::Action::"viewPhoto",
resource == PhotoApp::Photo::"vacationPhoto.jpg"
);

permit (
principal == PhotoApp::User::"stacey",
action == PhotoApp::Action::"viewPhoto",
resource
)
when { resource in PhotoApp::Account::"stacey" };

Start by reviewing Monaco Editor's custom-language integration and the existing VS Code Cedar extension mentioned in the issue. Determine whether the extension can provide Cedar parsing and error markers in Monaco, and define completion as Cedar being available by default with rule-level validation and diagnostics.
