Binary package “elpa-dumb-jump” in ubuntu lunar

jump to definition for multiple languages without configuration

 This package provides an Emacs "jump to definition" package with
 support for multiple programming languages that favors "just working"
 over speed or accuracy. This means minimal -- and ideally zero --
 configuration with absolutely no stored indexes (TAGS) or persistent
 background processes.
 .
 Dumb Jump performs best with The Silver Searcher `ag` or ripgrep
 `rg`.
