clj-refactor provides refactoring support for Clojure projects.
Here's a small teaser, helping you add a missing libspec:
It's highly recommended to install clj-refactor through package.el.
It's available on MELPA and MELPA Stable:
M-x package-install clj-refactor
(require 'clj-refactor)
(defun my-clojure-mode-hook ()
(clj-refactor-mode 1)
(yas-minor-mode 1) ; for adding require/use/import statements
;; This choice of keybinding leaves cider-macroexpand-1 unbound
(cljr-add-keybindings-with-prefix "C-c C-m"))
(add-hook 'clojure-mode-hook #'my-clojure-mode-hook)The more advanced refactorings require our nREPL middleware
refactor-nrepl. From
version 2.2.0 onwards if cider-jack-in is used it is injected
automatically.
profiles.clj or profile.boot don't need to be modified anymore for the above usecase!
On the other hand if a standalone REPL or an embedded nREPL server is used you will need to manually add this dependency (see below).
Either in your project's project.clj or in the :user
profile found at ~/.lein/profiles.clj:
:plugins [[refactor-nrepl "2.3.1"]
[cider/cider-nrepl "0.14.0"]]Check out the much longer installation page in the wiki for a less opinionated approach.
clj-refactor has quite a few settings you can tweak to change the
behavior of various commands. You can read more about that
here.
The analyzer
refactor-nrepl uses needs to eval the code too in order to be able
to build the AST we can work with. If that causes side effects like
writing files, opening connections to servers, modifying databases,
etc. performing certain refactoring functions on your code will do
that, too.
By default the user is warned about this when an AST dependent feature
is invoked. If this warning is an annoyance and the project can be
evalled without any risks set cljr-warn-on-eval to nil so
cljr-eagerly-build-asts-on-startup can take effect.
We create ASTs for all the namespaces at REPL start up if
cljr-warn-on-eval is set to nil. If that is not desired set
cljr-eagerly-build-asts-on-startup to nil in your emacs
configuration. AST dependent features at the moment are find usages,
rename symbol, extract function, inline symbol, rename file or dir, change function signature, promote function.
All functions in clj-refactor have a two-letter mnemonic
shortcut. E.g. rs for cljr-rename-symbol. Given the prefix choice
in the example setup you'd call this function by hitting C-c C-m rs
See the wiki for a complete list of available refactorings, demonstrations and customization points.
If you're having trouble remembering the mnemonic shortcuts, check out the hydra powered popup menus. They are described here.
An extensive changelog is available here.
Yes, please do. There's a suite of tests, so remember to add tests for your specific feature, or we might break it later.
You'll find the repo at:
https://github.com/clojure-emacs/clj-refactor.el
To fetch the test dependencies, install cask if you haven't already, then:
$ cd /path/to/clj-refactor
$ cask
Run the tests with:
$ ./run-tests.sh
Before submitting a patch, or a pull request, make sure all tests are passing and that your patch is in line with the contribution guidelines.
