Custom parameter info

[noman-khan1224]

The current node description is shown as:(property) Reference.$nodeDescription?: AstNodeDescription | undefined
I want to replace this with a custom description if it is available, and have this custom description inserted into the AstNode.

Request you to help with an approach for same?

Hey @noman-khan1224,

Just so I understand you correctly: You want to enrich the existing $nodeDescription property on the Reference interface with additional properties?

You would do that by overriding the AstNodeDescriptionProvider#createDescription method and returning a new interface that extends the existing AstNodeDescription. Afterwards, once the reference is linked, the contained $nodeDescription will be of the type that you returned from your createDescription override. In order to use that type in TypeScript, you will need to upcast:

const nodeDescription = ref.$nodeDescription as CustomNodeDescription | undefined;

The FieldMember displays the type of the entity. However, if a description is available for an entity in the AstNode, I want to display the custom description instead of the FieldMember.

Request you to help with an approach for same?

see DefaultCompletionProvider.createReferenceCompletionItem it calls detail: nodeDescription.type,
so you may want to customize there
