This is a massive (in a good way) Vim plugin for editing Ruby on Rails applications.

• Easy navigation of the Rails directory structure. gf considers context and knows about partials, fixtures, and much more. There are two commands, :A (alternate) and :R (related) for easy jumping between files, including favorites like model to schema, template to helper, and controller to functional test. Commands like :Emodel, :Eview, :Econtroller, are provided to :edit files by type, along with S, V, and T variants for :split, :vsplit, and :tabedit. Throw a bang on the end (:Emodel foo!) to automatically create the file with the standard boilerplate if it doesn't exist. :help rails-navigation

• Enhanced syntax highlighting. From has_and_belongs_to_many to distance_of_time_in_words, it's here.

• Interface to the rails command. Generally, use :Rails console to call rails console. Many commands have wrappers with additional features: :Generate controller Blog generates a blog controller and loads the generated files into the quickfix list, and :Runner wraps rails runner and doubles as a direct test runner. :help rails-exec

• Default task runner. Use :Rails (with no arguments) to run the current test, spec, or feature. Use :.Rails to do a focused run of just the method, example, or scenario on the current line. :Rails can also run arbitrary migrations, load individual fixtures, and more. :help rails-default-task

• Partial and concern extraction. In a view, :Extract {file} replaces the desired range (typically selected in visual line mode) with render '{file}', which is automatically created with your content. In a model or controller, a concern is created, with the appropriate include declaration left behind. :help rails-:Extract

• Fully customizable. Define "projections" at the global, app, or gem level to define navigation commands and override the alternate file, default rake task, syntax highlighting, abbreviations, and more. :help rails-projections.

• Integration with other plugins. If dispatch.vim is installed, :Rails and other command wrappers will use it for asynchronous execution. Users of abolish.vim get pluralize and tableize coercions, and users of bundler.vim get a smattering of features. :help rails-integration

If you don't have a preferred installation method, I recommend installing pathogen.vim, and then simply copy and paste:

cd ~/.vim/bundle
git clone https://github.com/tpope/vim-rails.git
vim -u NONE -c "helptags vim-rails/doc" -c q

While not strictly necessary, bundler.vim and dispatch.vim are highly recommended.

I installed the plugin and started Vim. Why does only the :Rails command exist?

This plugin cares about the current file, not the current working directory. Edit a file from a Rails application.

I opened a new tab. Why does only the :Rails command exist?

This plugin cares about the current file, not the current working directory. Edit a file from a Rails application. You can use :AT and the :T family of commands to open a new tab and edit a file at the same time.

Can I use rails.vim to edit Rails engines?

It's not supported, but if you touch config/environment.rb in the root of the engine, things should mostly work.

Can I use rails.vim to edit other Ruby projects?

I wrote rake.vim for exactly that purpose. It activates for any project with a Rakefile that's not a Rails application.

What Rails versions are supported?

All of them, although you may notice a few minor breakages if you dip below 3.0. A few features like syntax highlighting tend to reflect the latest version only.

Didn't rails.vim used to handle indent settings?

It got yanked after increasing contention over JavaScript. Check out sleuth.vim.
