Inflector (port of ActiveSupport::Inflector) 
This is an attempt to bring ActiveSupport's Inflector to Crystal. It started as a test idea for another project (Native Ruby extensions in Crystal), but then worked well enough that I decided to turn it into its own project.
Installation
Add this to your application's shard.yml:
dependencies:
inflector:
github: phoffer/inflector.cr
version: "~> 0.1.8"Somewhere in your app initialization, require "inflector".
Inflector.cr passes specs with Crystal versions starting at 0.17.4 and continuing through 0.24.2.
Additionally, there are core extensions to String and Int. If you want these, then require "inflector/core_ext instead of the standard require.
Usage
Some examples are probably best. There is a full set of examples in spec/inflector/readme_spec.cr
Inflector.camelize("active_model") # => "ActiveModel"
Inflector.underscore("ActiveModel") # => "active_model"
Inflector.humanize("employee_salary") # => "Employee salary"
Inflector.humanize("author_id") # => "Author"
Inflector.upcase_first("what a Lovely Day") # => "What a Lovely Day"
Inflector.titleize("x-men: the last stand") # => "X Men: The Last Stand"
Inflector.classify("ham_and_eggs") # => "HamAndEgg"
Inflector.demodulize("CoreExt::String::Inflections") # => "Inflections"
Inflector.deconstantize("Net::HTTP") # => "Net"
Inflector.foreign_key("Message") # => "message_id"
Inflector.ordinalize(1) # => "1st"
Inflector.ordinal(1) # => "st"
Inflector.dasherize("puni_puni") # => "puni-puni"Additionally, these are available if you required the core extensions. Additional examples are in spec/inflector/core_ext_spec
