Clojure Refactoring Mode
Provides automated refactoring for clojure code in Emacs/SLIME with clojure-mode.
Extract-fn - extracts the current expression and replaces it with a call to it.
Global rename - Replaces all calls to the symbol at point (in the current project) with the new name.
Thread-last - threads the current expression via
Thread-first - threads the current expression via
Unthread - unthreads the current expression.
Extract global - defines the current expression as a global var for
this namespace (using
Extract local - defines the current expression as a local variable for the current function definition.
Destructure map - Replaces calls to keywords on a particular map with a destructuring for that map in the args. Only works on top-level defn forms with one type of arity. Also only works for maps called with keywords.
Rename - Changes a name just in this sexp.
This mode can be installed as a leiningen plugin:
lein plugin install joodie/clojure-refactoring 0.6.5-SNAPSHOT
clojure-refactoring Emacs functions will then be available
whenever you run
M-x clojure-jack-in to start a SLIME session.
If you don't want to install as a leiningen plugin, you can also
declare clojure-refactoring as a dependency in your project.clj,
pom.xml or use some other dependency mechanism. As long as the
clojure-refactoring jar ends up on your class path,
will make sure the emacs interface is loaded.
If you don't use
clojure-jack-in, see the section "Customized
Clojure version issues
The master branch of clojure-refactoring (where the releases are prepared) is currently untestable under clojure 1.3, due to many dependencies on clojure-contrib 1.2. It probably will break something if you try to use it on clojure 1.3, so be careful.
Work is under way to get clojure-refactoring testable and working on
both clojure 1.2 and 1.3. If you want to help out with this or just
try it out, check out the
clojure-1.3 branch of the repository:
clojure-refactoring-prompt will be bound to
C-c C-f when you're
running SLIME. Press
C-c C-f at some point in the code and you will
be prompted to select a refactoring.
Note that global rename will be slow at first, as it has to read the source files into a cache.
NOTE: Still in alpha, has some breakages. Report any problems via Github Issues please.
clojure-mode (with swank-clojure 1.3.3 or higher), paredit, and thing at point.
Having ido-mode enabled is recommended when using clojure-refactoring-prompt.
If you don't want to use
clojure-jack-in, you should install the jar
as usual (as a dependency in your project or as a leiningen plugin)
and then extract
src/clojure_refactoring/payload/clojure-refactoring-mode.el and put
it on your elisp load-path (for instance, copy to or symlink from
(require 'clojure-refactoring-mode) in your
- Wherever possible, have a reverse of each refactoring.
- Refactoring should be quick
- Refactoring names should correspond to known refactorings from OO (where possible).
- Write a functional test for each refactoring (takes in a string and outputs the correct string).
After doing a global rename, refactoring-mode doesn't reload the namespaces in the right order, so there is sometimes a null pointer exception after doing this. For now, you can fix this by restarting swank.
Changes since 0.6.0
- fix tests and
- move cursor to arguments / position for inline docs of extracted function.
- hook into slime-mode-hook so that the refactoring mode is switched on for all clojure-mode buffers already opened when clojure-jack-in is executed.
- keep and re-indent formatting of extracted functions
- this code can now be installed as a leiningen plugin and hooks into clojure-jack-in with no more configuration required.
- all refactorings are now implemented as interactive elisp functions and take arguments where needed.
- ido is no longer required
- renamed clojure-refactoring-ido to clojure-refactoring-prompt
- clojure-refactoring-prompt allows quick selection (partial completion) of alternatives when run under ido-mode
- bug fix release
- licensing updates, parsing fixes, general maintenance
