The s extension adds Sequel::S, a module containing a private #S method that calls Sequel.expr. It's designed as a shortcut so that instead of:

Sequel.expr(:column) + 1
# or
Sequel.expr{column + 1}

you can just write:

S(:column) + 1
# or
S{column + 1}

To load the extension:

Sequel.extension :s

Then you can include the Sequel::S module into whatever classes or objects you care about:

Sequel::Model.send(:include, Sequel::S)   # available in model instance methods
Sequel::Model.extend(Sequel::S)           # available in model class methods
Sequel::Dataset.send(:include, Sequel::S) # available in dataset methods

or just into Object if you want it available everywhere:

Object.send(:include, Sequel::SQL)

If you are using Ruby 2+, and you would like to use refinements, you can use Sequel::S as a refinement, in which case the private #S method will be available on all objects while the refinement is active.

using Sequel::S

S(:column) + 1
