WordEx

Summary

WordEx is a word based pattern matching library. It is similar to Regexp. But while Regexp matches individual characters, WordEx is built to match word sequences.

Demo cases

With a variable word

WordEx.new("I saw them playing :game yesterday").
     match("I saw them playing tennis yesterday")
# => {:game => "tennis"}

With a variable substring

WordEx.new("I saw them +doing yesterday").
     match("I saw them playing tennis yesterday")
# => {:doing=>"playing tennis"}

Automatic conversion

WordEx.new("I have :apple_count@Integer apples").
     match("I have 5 apples")
# => {:apple_count=>5}

Validation

WordEx.new("I have :apple_count@Integer apples").
     match("I have many apples")
# => nil

Enforce positive values

WordEx.new("I have :apple_count@+Integer apples").
     match("I have -5 apples")
# => nil
