I’m just blogging this because it took me ages to figure out, it seems so simple now but I guess that’s how it usually goes.<\/p>\n

The problem I have is I want a plugin to be able to either make a method using the normal Ruby def foo<\/em> or via some DSL’ish helpers.<\/p>\n

<\/p>\n

\r\nclass Foo \"do_something\", :description => \"foo\")\r\n\r\n   def do_something_action\r\n   end\r\n\r\n   register_action(:name => \"do_something_else\", :description => \"foo\") do\r\n      # body of the action here\r\n   end\r\nend\r\n<\/pre>\n
<\/code><\/p>\n
The above code should make me two methods – do_something_action<\/em> and do_something_else_action<\/em> – they should be identical to viewers from the outside.  Here’s the base class that makes this happen correctly:<\/p>\n
<\/p>\n
\r\nclass Base\r\n   def self.register_input(input, &block)\r\n      name = input[:name]\r\n\r\n      self.module_eval { define_method(\"#{name}_action\", &block) } if block_given?\r\n   end\r\nend\r\n<\/pre>\n
<\/code><\/p>\n
It’s pretty simple, we’re just using define_method in the scope of the module and that does the rest.<\/p>\n","protected":false},"excerpt":{"rendered":"
