Dumb Jump is an Emacs "jump to definition" package with support for 50+ programming languages that favors "just working". This means minimal -- and ideally zero-configuration with absolutely no stored indexes (TAGS) or persistent background processes. Dumb Jump requires at least GNU Emacs 24.3. Dumb Jump uses The Silver Searcher ag, ripgrep rg, or grep to find potential definitions of a function or variable under point. It uses a set of regular expressions based on the file extension, or major-mode, of the current buffer. The matches are run through a shared set of heuristic methods to find the best candidate to jump to. If it can't decide it will present the user with a list in a pop-menu, helm, or ivy (see dumb-jump-selector). For the currently supported languages it seems to do a good job of finding what you want. If you find a case where it does not work as expected do not hesitate to open an issue. It can be slow if it needs to use grep and/or a project is large.
