Using Slap Chop

Remove comments from your code!

Visit slap-chop and upload a ruby or js file. Select the uncomment option and Slap Chop will chop (see what I did there) all of the file's comments and send you back a brand spanking new comment free file.

Remove logs from your code!

But there's more. If you select the unlog option, Slap Chop will remove all log statements from the uploaded file. in ruby p, puts, print, in js console.log .

Adding regexps

If you would like to add a regular expression for removing comments/logs from files of a different language, regexps can be added to Remover.patterns in app/controllers/concerns/remover.rb. In order to select the proper algorithm, keys of the patterns hash must follow the convention of <action>.<extension> i.e., uncomment.rb

An example of an added regexp

  # app/controllers/concerns/remover.rb
  
  def self.patterns
    {
      'uncomment.rb' => Regexp.new('#.*$|^=begin(.|\s)*^=end'),
      'uncomment.js' => Regexp.new('//.*$|/\*(.|\s)*\*/'),
      'unlog.rb'     => Regexp.new('(p |print |puts ).*$'),
      'unlog.js'     => Regexp.new('console\.log\(.*\); ?'),
      #c++
      'unlog.cpp'    => Regexp.new('<corresponding regexp here>')
    }
  end

Stretch

It would be amazing to be able to upload a rails project directory and remove all comments/logs from all its .rb and .js files. I have been able to zip and unzip uploaded directories but am having trouble figuring out how deal with zipping nested directories. It would be great to figure this out.
