ERB::FileOut

By default, ERB compiles a script from the template and stores the result as a string in memory. This is not great when dealing with templates that could end up being very large after rendering. ERB::FileOut provides a way to write the result of a template to disk instead of storing it in memory.

Add this line to your application's Gemfile:

gem 'erb-file_out'

And then execute:

$ bundle

Or install it yourself as:

$ gem install erb-file_out

ERB::FileOut has the same API as ERB, except that it returns a path string instead of the template result.

  require 'erb/file_out'
  require 'pathname'

  result = Pathname.new(ERB::FileOut.new("This: <%= 'is' %> Pretty: <%= 'cool' %>")
  result.read

  # => 'This: is Pretty: cool'
