It would be great to have some form of breadcrumb-jump in imenu.el since it's useful on its own even for someone who doesn't use breadcrumbs. > You can look at it for an implementation idea.

Here are some observations while testing on emacs/test/manual/etags/ruby-src/test.rb. Both ruby-mode and ruby-ts-mode provide a list that is already flat: ruby-mode: ModuleExample ModuleExample#ModuleExample.module_class_method ModuleExample#module_instance_method ModuleExample::ClassExample ModuleExample::ClassExample#+ ModuleExample::ClassExample#ClassExample.class_method ModuleExample::ClassExample#instance_method ruby-ts-mode: ModuleExample ModuleExample#module_instance_method ModuleExample.module_class_method ModuleExample::ClassExample ModuleExample::ClassExample#+ ModuleExample::ClassExample#instance_method ModuleExample::ClassExample.class_method When eglot is enabled then imenu-create-index-function returns a tree. What is interesting is that breadcrumb-jump already correctly handles both a flat list and a tree: a flat list in breadcrumb-jump completions is exactly the same as in 'imenu': ModuleExample ModuleExample#module_instance_method ModuleExample.module_class_method ModuleExample::ClassExample ModuleExample::ClassExample#+ ModuleExample::ClassExample#instance_method ModuleExample::ClassExample.class_method a tree from eglot in breadcrumb-jump completions: Class > ModuleExample > ClassExample Method > ClassExample > class_method Method > ModuleExample > module_class_method Method > ModuleExample > module_instance_method Method > ModuleExample::ClassExample > + Method > ModuleExample::ClassExample > instance_method Module > > ModuleExample is still usable even without special characters like "#". > It shouldn't be needed here at all, but in case anyone's thinking > about it, please avoid messing with imenu's internal representation of > hierarchies as that structure is relied upon by many extensions (not just > mine, but several others).

Indeed, it's unfortunate that imenu--make-index-alist and imenu--index-alist are named as internal.
