Overview

Builds the LSP ‘Hover.contents` markdown body. Dispatches on the hovered Prism node class so each shape (method call, constant, local, literal, …) gets the most relevant type-aware presentation.

Slice A1 (this commit) ships:

  • default body bit-for-bit matching the LSP v1 slice 5 output (‘type:` / `erased:` / `node:`),

  • ‘Prism::CallNode` specialisation surfacing the receiver type + RBS-erased method signature.

Slices A2-A4 extend the dispatch with constant / local / ivar / literal renderers per ‘docs/design/20260517-lsp-hover-completion.md`.

Instance Method Details

#render(node:, type:, node_scope_lookup:) ⇒ Object

Parameters:

  • node_scope_lookup (#[]) —

    node-to-scope table built by ‘ScopeIndexer.index`. The renderer indexes into it to retrieve the receiver’s narrow scope when specialising on ‘CallNode`. The lookup never returns nil (the indexer’s Hash carries ‘default_scope` as its default value), so the renderer trusts the lookup result.
