Ruby / Roda - Web Framework / Plugins / :hash_matcher

Introduction

The :hash_matcher plugin adds the #.hash_matcher class method, which allows for easily defining Hash matchers:

class App < Roda
  
  hash_matcher(:foo) do |v|
    self['foo'] == v
  end
  
  route do
    
    r.on :foo => 'bar' do
      # matches when param foo has value bar
    end
    
  end
  
end

ClassMethods

#.hash_matcher(key, &block)

Create a match_#{key} method in the request class using the given block, so that using a hash key in a request match method will call the block.

The block should return nil or false to not match, and anything else to match.

See the HashMatcher module documentation for an example.
