clj-refactor.el

This functionality is provided by `xref-find-definition`[1]. For many languages this defaults to using keywords from a generated tags index file, but many modes have a language server or some other more specific facility to provide this functionality at runtime. I'm not familiar with what provides that functionality for C/C++, but Ruby has `robe`, python has `jedi`, clojure has `cider`, rust has `racer`, etc. It generally requires a some setup for each language you use, but there is broad support for this functionality (and it often provides some form of symbol auto-completion as well). Some modes also support limited refactoring tools[2], but that's not quite as common. [1] https://www.gnu.org/software/emacs/manual/html_node/emacs/Xr...

> First, ns-unmap your old name (a refactoring tool should do that for your, I guess). clj-refactor has a cljr-rename-symbol function. https://github.com/clojure-emacs/clj-refactor.el Here's a full list of its features: https://github.com/clojure-emacs/clj-refactor.el/wiki

clj-refactor is coming along quite nicely... https://github.com/clojure-emacs/clj-refactor.el/wiki/cljr-r...

Check out https://github.com/clojure-emacs/clj-refactor.el The intellij plugin for clojure called Cursive also has support for project wide renaming.

I have nothing against Cursive, and in fact, have been eying it from afar. But this kind of comment is just needlessly dismissive with little in the way of substance, as far as I can tell. Would you like to expand on what these features that Cursive has that are "Categorically better" than Emacs'? I'm not saying there isn't any, and certainly I've used better refactoring tools than https://github.com/clojure-emacs/clj-refactor.el in other languages. But what on earth is wrong with the navigation? The main advantage I've seen form a colleague is the highlighting automatically of usages, but I'm pretty sure I can set that up in Emacs too.

For those curious, escherize means: [1] https://github.com/clojure-emacs/cider [2] https://github.com/clojure-emacs/clj-refactor.el The examples in [3] showcase the features of clj-refactor rather neatly. [3] https://github.com/clojure-emacs/clj-refactor.el/tree/master...

There is also Ecukes[1] which lets you write Cucumber style integration tests for emacs. We use these exclusively when writing the elisp part of clj-refactor[2]. These are so high level, and readable, that they can often double as documentation. The only real gripe I have with Ecukes is that the diff of the actual and expected output could be better. Turning on whitespace-mode while writing these scenarios have often solved an otherwise inexplicable test failure.
