Nothing could be more paramount, in the writing of code, than to make it understandable and legible. You will be greatly assisted in the latter task, if you employ a beautifier, that styles everything automatically for you. If you are using Sublime Text 3 as your text editor, then you can employ the “BeautifyRuby” package to help automatically indent and style your rails templates.

Instructions:

• First ensure that the htmlbeautifier gem is installed. Go to your terminal type in sudo gem install htmlbeautifier.
• Then go to your Sublime Text 3. Hit CTRL + SHIFT + P and type in the words Install Package till you get the below picture - click on the install package drop down selection.

• Wait a couple of seconds (perhaps 5 or so)Now search for ‘beautifyRuby’ and select that from the list. The package should install.

• If you get the following annoying error: “Error: invalid output. Check your ruby interpreter setting” then make sure that htmlbeautifier is installed, and secondly, make sure you have set your ruby path properly - go to the command line and type in which ruby and you will get the path. Paste that path into the default settings for BeautifyRuby - as the value to the ‘ruby’ key. My settings are posted below - but I’m using rbenv as my ruby version manager, and my path will be different to yours. To get to the settings, click on Preferences -> Package Settings -> BeautifyRuby -> Setting - Default.

Here is a gif which shows you how to do all that:

{
    // Would you prefer a tab or two spaces to represent a tab
    // The default is two spaces represented by 'space'
    // anything else will use one tab character
    "ruby" : "/home/koshy/.rbenv/shims/ruby",
    "file_patterns": ["\\.html\\.erb", "\\.rb", "\\.rake", "Rakefile", "Gemfile", "Vagrantfile"],
    "html_erb_patterns": ["\\.html\\.erb"],
    "run_on_save": true,
    "save_on_beautify": true
}

Notes:

Now when I save, all my ruby templates will be automatically styled! Perfect.
