Public Instance methods

default(hostname, &block)

Register the default hostname. If a block is provided, it is called with the host if there is no match for one of the hostnames provided to to. If the block returns nil/false, the hostname given to this method is used.

[show source] 
    # File lib/roda/plugins/host_routing.rb
151 def default(hostname, &block)
152   @default_host = hostname
153   @default_block = block
154 end
process(&block)

Run the DSL for the given block.

[show source] 
    # File lib/roda/plugins/host_routing.rb
120 def process(&block)
121   instance_exec(self, &block)
122 
123   if !@default_host
124     raise RodaError, "must call default method inside host_routing plugin block to set default host"
125   end
126 
127   @hosts.concat(@host_hash.values)
128   @hosts << @default_host
129   @hosts.uniq!
130   [@hosts.freeze, @host_hash.freeze, @default_block, @default_host].freeze
131 end
register(*hosts)

Register hosts that can be returned. This is only needed if calling register with a block, where the block can return a value that doesn’t match a host given to to or default.

[show source] 
    # File lib/roda/plugins/host_routing.rb
136 def register(*hosts)
137   @hosts = hosts
138 end
to(host, *hostnames)

Treat all given hostnames as routing to the give host.

[show source] 
    # File lib/roda/plugins/host_routing.rb
141 def to(host, *hostnames)
142   hostnames.each do |hostname|
143     @host_hash[hostname] = host
144   end
145 end
