MinifiedErb

Minifies output of erb templates compilation: eliminates line-breaks, tabs and spaces

Installation

Add this line to your application's Gemfile:

gem 'minified_erb'

And then execute:

$ bundle

Or install it yourself as:

$ gem install minified_erb

Usage

require 'erubis'
require 'minified_erb'

template = <<-HEREDOC
<div>
  <% 3.times do %>
    <span></span>
  <% end %>
</div>
HEREDOC

erb = Erubis::Eruby.new(template, minify: true)

p erb.result # => "<div><span></span><span></span><span></span></div>"

Supported Erb engines

  • Erubis
  • Erbse

Rails support

ActionView uses erubis. The minify: true is passed for all templates with text/html type.

Limitations

Only full line comments are supported. Comments on the same line with code will lead to various issues.

<div>
  <%# this works %>
  <% if true # this will lead to a syntax error %>
  <% end     # because this line will become commented out too %>
</div>

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
