Make lsp-ui-imenu hierarchical · Issue #73 · emacs-lsp/lsp-ui · GitHub

lsp--imenu-create-index from lsp-imenu.el (in lsp-mode) does not take hierarchy into consideration. I think it might be useful if it can be used to visualize arbitrary symbol hierarchy, where the most common ones are:

• member hierarchy: members of a type (e.g. members of a class/struct; enumeration constants in an enum; members in a module/namespace) are recursively expanded

struct B { B* x; int b; };
struct A { B b;  int c; };

may expand to

A
  B b
    int b
    B* x    // pointer types can optionally be expanded
      int b
      B* x   // but the client needs to explicitly trigger the expansion to avoid infinite recursion
        int b
        B* x
  int c

• caller tree of a callable (e.g. function,method,...). (may be generalized to reference tree)

void foo() { bar(); quz(); foo(); }
void bar() { quz(); }

is visualized as:

quz
  foo
    foo   // explicit expansion to avoid infinite recursion
  bar
    foo
      foo

• inheritance hierarchy (e.g. all derived classes of a C++ base class, or overriden virtual functions of a base function; Rust trait/impl; Java interface...)

struct B : A {};
struct C : B {};
struct D : B {};

is visualized as:

LSP spec

interface SymbolInformation {
	name: string;
        // id is missing; name may be insufficient to identify a symbol
	kind: number;
	location: Location;
	containerName?: string;  // containerName is a string. If it was an identifier, it could be used to describe a parent pointer tree
}

When the point is at a reference of a symbol, textDocument/documentHighlight or other mechanism can be employed to highlight the imenu entry and there can be some keys to trigger these different kinds of hierarchies.

• $cquery/typeHierarchyTree is a kind of inheritance hierarchy
• $cquery/memberHierarchy is a kind of member hierarchy.
• $cquery/callerTreeInitial is a kind of call hierarchy.

I'd like to know if such extensions have been implemented in other servers. We should unify these server API interfaces and even standardize it.
