Projectile Rails

Note on the changed keybindings

Please note that the keybindings had change. I know this might be very intrusive for you guys but the keybindings had to be rethought. You can scroll to here to see the newest version. Basically the new "run" map had been added accessible through C-c r !. From this map you can run console/server/rake/generate commands. Also for the sake of ergonomy you can still run projectile-rails-console via C-c r r and projectile-rails-server via C-c r R. The goto have been stripped out from the projectile-rails-find-current-.* commands. If you want them back you can do something like this:

(define-key projectile-rails-mode-goto-map (kbd "m") 'projectile-rails-find-current-model)

Synopsis

Projectile Rails is a minor mode for working with the Rails project in GNU Emacs. Internally it based on Projectile.

It means that you can use Projectile's commands for greping (or acking) files, run tests, switch between projects, etc.

With Projectile Rails you are able to:

• navigate through rails resources (controllers, views, helpers and so on)
• jump to ruby classes and template files
• run rake
• run rails console
• run rails generate
• run rails server
• open log files with auto-revert-mode on
• see rails keywords highlighted
• take advantage of zeus and spring preloaders

It can be a replacement for rinari.

Setup

Installation

Melpa

Once you have setup Melpa you can use package-install command to install Projectile Rails. The package name is projectile-rails.

Usage

Hooking up with Projectile

To make it start alongside projectile-mode:

(add-hook 'projectile-mode-hook 'projectile-rails-on)

That will start it only if the current project is a Rails project.

Probably you should read Projectile's README on setting up the completion system, caching and indexing files. Although the default settings are quite sensible and you should be ready to go without much tweaking.

Customizing

The mode's buffers will have the Rails keywords highlighted. To turn it off:

(setq projectile-rails-add-keywords nil)

If you are using yasnippet and you open a new file it will be filled with a skeleton class. To turn it off:

(setq projectile-rails-expand-snippet nil)

By default the buffer of the projectile-rails-server-mode is applying the ansi colors. If you find it slow you can disable it with:

(setq projectile-rails-server-mode-ansi-colors nil)

You might want to create your own keybinding for your favorite commands. For example:

(define-key projectile-rails-mode-map (kbd "s-m")   'projectile-rails-find-model)
(define-key projectile-rails-mode-map (kbd "s-c")   'projectile-rails-find-controller)
(define-key projectile-rails-mode-map (kbd "s-v")   'projectile-rails-find-view)
(define-key projectile-rails-mode-map (kbd "s-RET") 'projectile-rails-goto-file-at-point)
(define-key projectile-rails-mode-map (kbd "C-c g")  projectile-rails-mode-goto-map)

Discover

There's also integration with discover.el. The key that trigger the menu is s-r (the "s" stands for Win/Command key).

Beyond

Consider installing other Emacs packages that can help you working specifically with Rails projects.

Templates

Extension	Alternatives
erb	web-mode, mmm-mode, rhtml-mode
haml	haml-mode
slim	emacs-slim
yaml	yaml-mode

Running ruby gems

Some of the Projectile Rails functions run rake or rails executables. If you are using a ruby version manager you might need to configure your Emacs to play nicely with it.

• rvm.el
• rbenv.el

OS X users might want to look at exec-path-from-shell.

Miscellaneous

• bundler.el to interact with Bundler.
• rspec-mode to run and edit spec files.
• feature-mode to edit feature files.
• robe to view gems documentation and jump to methods and classes definitions.
• magit to interact with git.

Caveat

Running pry instead of irb

• Pry's paging is not working in emacs. It should be disabled with Pry.config.pager = false. Reference.

• When projectile-rails-console runs rails console using a pre-loader (zeus or spring) and pry's indent correction is enabled then pry will insert some ansi codes that are misinterpreted by comint-mode. A workaround is to disable the indentation correction with Pry.config.correct_indent = false. Reference. Issue.

Contributors

Here's a list of the people that contributed to the projects. Many thanks! :)

Contribution

Install cask if you haven't already, then:

$ cd /path/to/projectile-rails
$ cask

Run all tests with:

$ make test

For all of them to pass you will need the bundle executable in your path.
