Gemfiler will take your Gemfile and make it nice. It will alphabetize and group everything correctly. It can also turn hash syntax into Ruby's 1.9 hash syntax, and align versions / options nicely.

gem install gemfiler

Once you've installed gemfiler, you'll get the gemfiler executable.

• cd into the project with the gemfile you'd like to prettify.
• type gemfiler file (If you'd like to specify a Gemfile, type gemfiler file OtherGemfile)
• Voila!

To see a list of options, type gemfiler help file

gemfiler file --ruby19_hashes Will use the 1.9 hash syntax

gemfiler file --nice_spaces Will align all versions / options

Gemfiler works by acting like Bundler, it executes the Gemfile under a shim, and passes all of the gems as objects around Gemfiler.

• Comments go away (Working on this)
• Statements will go away, if you have any if statements, or anything other than bundler commands, it will either fail or remove the statement.
