rqrcode is a library for encoding QR Codes. The simple interface allows you to create QR Code data structures and then render them in the way you choose.

ruby_parser (RP) is a ruby parser written in pure ruby (utilizing racc--which does by default use a C extension). It outputs s-expressions which can be manipulated and converted back to ruby via the ruby2ruby gem. As an example: def conditional1 arg1 return 1 if arg1 == 0 return 0 end becomes: s(:defn, :conditional1, s(:args, :arg1), s(:if, s(:call, s(:lvar, :arg1), :==, s(:lit, 0)), s(:return, s(:lit, 1)), nil), s(:return, s(:lit, 0))) Tested against 801,039 files from the latest of all rubygems (as of 2013-05): * 1.8 parser is at 99.9739% accuracy, 3.651 sigma * 1.9 parser is at 99.9940% accuracy, 4.013 sigma * 2.0 parser is at 99.9939% accuracy, 4.008 sigma * 2.6 parser is at 99.9972% accuracy, 4.191 sigma * 3.0 parser has a 100% parse rate. * Tested against 2,672,412 unique ruby files across 167k gems. * As do all the others now, basically.

Paranoia is a re-implementation of acts_as_paranoid for Rails 5, 6, and 7, using much, much, much less code. You would use either plugin / gem if you wished that when you called destroy on an Active Record object that it didn't actually destroy it, but just "hid" the record. Paranoia does this by setting a deleted_at field to the current time when you destroy a record, and hides it by scoping all queries on your model to only include records which do not have a deleted_at field.

jaro_winkler is an implementation of Jaro-Winkler \ distance algorithm which is written in C extension and will fallback to pure \ Ruby version in platforms other than MRI/KRI like JRuby or Rubinius. Both of \ C and Ruby implementation support any kind of string encoding, such as \ UTF-8, EUC-JP, Big5, etc.

BinData is a declarative way to read and write binary file formats. This means the programmer specifies *what* the format of the binary data is, and BinData works out *how* to read and write data in this format. It is an easier ( and more readable ) alternative to ruby's #pack and #unpack methods.
