Erector::ConditionalClasses

erector-conditional_classes is a rubygem that makes using the conditional application of html classes in your views nicer.

Erector provides a wonderful chain-based api for applying classes to an element:

span.foo.bar.baz "hello" # => '<span class="foo bar baz">hello</span>'

The pain comes when you need to conditionally apply classes to an element:

classes = [:foo]
classes << :bar if some_condition?

span("hello", :class => classes) # => '<span class="foo">hello</span>'

This gem provides support in the chaining API for conditionals:

#block based
span.foo.bar(:if => some_condition?){ text "hello" } # => '<span class="foo">hello</span>'

# non-block content
span("hello").foo.bar(:if => some_condition?) # => '<span class="foo">hello</span>'

Add this line to your application's Gemfile:

gem 'erector-conditional_classes'

And then execute:

$ bundle

Or install it yourself as:

$ gem install erector-conditional_classes

just:

require 'erector/conditional_classes'

and you're good to go.
