Vim中格式错误的红宝石代码

Question

When I format a PHP file in vim it's ok, but when I format a Ruby file, VIM format code bad.

For example:

class PostsController < ApplicationController

                skip_before_filter :authorize, :only => [ :index, :show ]

  def index
        @posts = Post.all
     end

  def show
    @post = Post.find(:first, :conditions => [ "id = ?", params[:id]], :include => [ :user, :category, :gallery ])
                  @photos = Photo.where(:gallery_id => @post.gallery.id).all
      end
   end

When I enter the command gg=G , I get.

class PostsController < ApplicationController

skip_before_filter :authorize, :only => [ :index, :show ]

def index
@posts = Post.all
end

def show
@post = Post.find(:first, :conditions => [ "id = ?", params[:id]], :include => [ :user, :category, :gallery ])
@photos = Photo.where(:gallery_id => @post.gallery.id).all
end
end

Please help me.

Answer 1

To get Ruby indenting working you need to provide indenting configuration. Vim itself is not able to indent Ruby code, you could set the indentexpr variable to some similar language (like basic), but you wont be happy with results. Check your smartindent and indentexpr variables:

:set si?
:set indentexpr?

In my case they are set:

nosmartindent
indentexpr=GetRubyIndent()

The best way to configure vim for ruby is to use vim-ruby plugin: https://github.com/vim-ruby/vim-ruby

A more general formatting plugin exists, called vim-autoformat . Among others, it integrates rbeautify to provide stronger formatting than just fixing indentation.

Answer 3

I am not sure if I have any Vim plugins, because I use it at work (and was already installed). However, for what it's worth, here's some of my .vimrc file.

syntax enable             " Enable syntax highlighting
syntax on
set expandtab             " Use spaces instead of tabs
set shiftwidth=2          " 1 tab == 4 spaces
set tabstop=2             " 1 tab == 4 spaces

I actually have set smartindent commented out in the file. [1]

If you want replace any tab-character with spaces (set in the above .vimrc ), I suggest the following command in your working file: set :retab [2]
