Latest commit 408ab1f Nov 17, 2017 @eggsyntax eggsyntax committed with expez [Fix #394] Let user specify default language context
When the user enters an apparent namespace like `somelib/`, and the
language context is ambiguous, clj-refactor creates a popup asking the
user to specify whether the context is "clj" or "cljs".

This change allows the user to specify a language context which should
be assumed, so that clj-refactor will choose that context in ambiguous
cases rather than creating a popup.

Default behavior is still to create the popup; this change only
creates a variable that lets the user override that behavior.

clj-refactor.el

clj-refactor provides refactoring support for Clojure projects.

Here's a small teaser, helping you add a missing libspec:

Installation

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

Setup

(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.

In case refactor-nrepl used for advanced refactorings

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.

Usage

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.
