Rack server support is broken

[Domon]

Steps to reproduce

1. Initialize a Middleman project with middleman init --rack.
2. Run any command to initialize a rack server, e.g. rackup, puma, ...

Expected behavior

A rack server is up and running.

Actual behavior

An error is raised:

NoMethodError: undefined method `server' for Middleman:Module

Affected version

I found that this regression is caused by 14104aa, so the rack server support is broken in versions after that commit, i.e. v3.3.9, v3.3.10.

Thanks for reporting, will investigate.

It looks like this no longer works again.

I've got the same undefined method 'server' for Middleman:Module (NoMethodError) with the fresh version of middleman.

My Gemfile:

source 'https://rubygems.org'

gem 'middleman', '~> 4.2'
gem 'middleman-autoprefixer', '~> 2.7'
gem 'tzinfo-data', platforms: [:mswin, :mingw, :jruby]
gem 'wdm', '~> 0.1', platforms: [:mswin, :mingw]

gem 'unicorn'
