instance method

ERB#def_module

def_module(methodname='erb')

# File tmp/rubies/ruby-3.1.3/lib/erb.rb, line 957
def def_module(methodname='erb')
  mod = Module.new
  def_method(mod, methodname, @filename || '(ERB)')
  mod
end

Create unnamed module, define methodname as instance method of it, and return it.

example:

Example

filename = 'example.rhtml'   # 'arg1' and 'arg2' are used in example.rhtml
erb = ERB.new(File.read(filename))
erb.filename = filename
MyModule = erb.def_module('render(arg1, arg2)')
class MyClass
  include MyModule
end
