Call and Type Hierarchy Support?

[lukebsh]

Are there any plans to implement the call and type hierarchy LSP methods?

These seem like quite useful features and would definitely help with navigating larger codebases.

Love ya work though.

I do not see call hierarchy or LSP type hierarchy support in the current language-server feature set.

The documented LSP support table lists related navigation features such as goto declaration/type/implementation, find references, document/workspace symbols, selection range, rename, etc., but not call hierarchy or type hierarchy. In the source, the reference-finder language-server extension registers handlers for:

• textDocument/definition
• textDocument/typeDefinition
• textDocument/implementation
• textDocument/references

Those handlers advertise definitionProvider, typeDefinitionProvider, implementationProvider, and referencesProvider. I do not see handlers or capabilities for textDocument/prepareCallHierarchy, callHierarchy/*, textDocument/prepareTypeHierarchy, or typeHierarchy/*.

So this looks like a feature request rather than an existing option to enable. Implementing it would need new LSP handlers/capability registration plus model support for incoming/outgoing calls and type hierarchy items.

I'd certainly be open to adding support.
