The "cheap batch" subset that is genuine template-fill: these four
return the exact `Location | Location[] | LocationLink[] | null`
shape `textDocument/definition` already parses, so no new parsing —
only a kind discriminator so they don't collide on (server, uri).
- src/locations.rs: a (server, uri, kind)-keyed store whose value
type is the reused crate::definition::DefinitionResponse. The
proven definition store + Lua API are untouched.
- lsp.rs: ResponseRoute::Locations { uri, kind }; one absorb arm; a
DRY request_locations helper + request_references /
request_declaration / request_type_definition /
request_implementation. references sends
context.includeDeclaration. Supersede keys derive from each
kind's distinct method, so the four don't cancel each other.
- Lua: _request_*_raw bindings + install_locations exposing
pmacs.references / .declaration / .type_definition /
.implementation ({ locations, clear }, mirroring pmacs.definition,
reusing definition_response_to_lua). lsp.lua Handle wrappers + a
lsp.find-references command bound to M-? (modeline summary;
references-list buffer is future UX, like the hover panel).
- Tests: locations.rs unit tests (kind labels distinct; keys don't
collide); e2e driving all four through the async bridge and
asserting each routes to its own kind slot (fake returns distinct
lines 11/21/31/41).
Scoped: documentSymbol / workspaceSymbol / documentHighlight return
different shapes (new parsing) — a separate follow-up, not crammed
in here.
