syntax_fix gem goes through all files and directories and change the old Ruby 1.8 syntax to a new one.

What we've got so far:

• change hash style from ':key => "value"' to 'key: "value"'

gem install syntax_fix

OR

Put this line in your Gemfile: gem 'syntax_fix'

Then bundle: $ bundle

-h or --help - output all the possible arguments that you can pass from a command line

-v or --verbose - be verbose about the actions

-p [PATH] or --path [PATH] - specify the relative path to start actions from
