This package enhances the Standard ERB library, including providing:
- A method for returning the processed contents of a named erb file (ERB.process_file). This makes it very easy to include one erb file within another erb file.
<%= require 'rubygems' require 'erbextensions' $recipient = "Dr. Frankenstein" $position = "assistant" $source = "Mad Scientist Monthly" $field = "resurrection science" $skill = "restraining experimental subjects" # # This call would be much cleaner with the 'relative' gem: # ERB::process_file(PathRelativeToCaller.new("template.erb")) # ERB::process_file(File.join(File.dirname(__FILE__), "template.erb")) %>
Dear <%= $recipient %>, I am writing to be considered for the <%= $position %> position that you recently advertised in <%= $source %>. I possess a keen interest in <%= $field %> and am eager to apply my deep skills in <%= $skill %>. I have enclosed my resume for your consideration. Sincerely, Igor
The example consists of a cover letter that is templated on a few variables in order to adjust the letter’s pitch to match the job being sought. After the template variables are initialized in template_wrapper.erb, an ERB.process_file call includes the expanded contents of template.erb. On the command line, run:
The output of erb examples/template_wrapper.erb:
Dear Dr. Frankenstein, I am writing to be considered for the assistant position that you recently advertised in Mad Scientist Monthly. I possess a keen interest in resurrection science and am eager to apply my deep skills in restraining experimental subjects. I have enclosed my resume for your consideration. Sincerely, Igor
This gem best is used with the relative gem (relative.rubyforge.org). The relative gem upgrades the Ruby core and standard libraries to handle paths relative to source files, which makes referencing a file within an erb file much easier (see the comment in examples/template_wrapper.erb for a demonstration)
Hoe is required but only for running the tests.
sudo gem install erbextensions
