Use Ivy as the interface to select from xref candidates.
The preferred way to install ivy-xref is via MELPA - then you can just M-x package-install RET ivy-xref RET
To enable then simply add the following to your init file:
(require 'ivy-xref) ;; xref initialization is different in Emacs 27 - there are two different ;; variables which can be set rather than just one (when (>= emacs-major-version 27) (setq xref-show-definitions-function #'ivy-xref-show-defs)) ;; Necessary in Emacs <27. In Emacs 27 it will affect all xref-based ;; commands other than xref-find-definitions (e.g. project-find-regexp) ;; as well (setq xref-show-xrefs-function #'ivy-xref-show-xrefs)
We recommend to use use-package to make this automatic:
(use-package ivy-xref
:ensure t
:init
;; xref initialization is different in Emacs 27 - there are two different
;; variables which can be set rather than just one
(when (>= emacs-major-version 27)
(setq xref-show-definitions-function #'ivy-xref-show-defs))
;; Necessary in Emacs <27. In Emacs 27 it will affect all xref-based
;; commands other than xref-find-definitions (e.g. project-find-regexp)
;; as well
(setq xref-show-xrefs-function #'ivy-xref-show-xrefs))
If you would like to install the package manually, download or clone it and place within Emacs' load-path, then enable as above.
