How can I include a module?

[ejstembler]

Normally one would add module includes inside the class. How can this be done with FunctionsFramework?

For example, this doesn't work:

FunctionsFramework.http 'my_function' do |request|
  include GoogleCloudLoggable

  # ...
end

NoMethodError: undefined method `include' for #<#<Class:0x000029e70e0ca9f8>:0x000029e70f56a6b0 @__globals={:function_name=>\"my_function\", :function_type=>:http}, @__logger=#<Logger:0x000029e70e0b3398 @level=1, @progname=nil, @default_formatter=#<Logger::Formatter:0x000029e70e0b3258 @datetime_format=nil>, @formatter=nil, @logdev=#<Logger::LogDevice:0x000029e70e0b30a0 @shift_period_suffix=nil, @shift_size=nil, @shift_age=nil, @filename=nil, @dev=#<IO:<STDERR>>, @binmode=false, @mon_data=#<Monitor:0x000029e70e0b2fd8>, @mon_data_owner_object_id=2460>>>", ...

Hi @ejstembler, apologies for not noticing this sooner.

Conceptually, the block you provide to FunctionsFramework.http is a "function" (i.e. a method), not a class, so you can't call Module#include from it. But you can call Object#extend. The following should work:

FunctionsFramework.http 'my_function' do |request|
  extend GoogleCloudLoggable

  # ...
end

That said, let's leave this issue open. You bring up a good use case, and I think it would be good to provide a way to include modules in the underlying class rather than extending every instance individually.

@dazuma Do you already know what you'd like to happen in the block to make include work normally or would a PR for this be acceptable from an outside contributor (me)?

@Spaceghost if you're still up to it, a PR would be welcome.
