`module Application`

The environment configuration for a Presently application server.

Extends the Lively environment with Presently-specific middleware and configuration. Override #slides_root and #templates_roots to customize paths.

Definitions

`def slides_root`

The root directory containing slide Markdown files.

Signature

returns　String: Absolute path to the slides root.

Implementation

def slides_root
	File.expand_path("slides", self.root)
end

`def templates_roots`

Additional directories to search for slide templates. These are searched before the gem's bundled templates, allowing selective overrides without duplicating all templates.

Signature

returns　Array(String): Ordered list of template directories.

Implementation

def templates_roots
	[File.expand_path("templates", self.root)].select{|d| File.directory?(d)}
end

`def application`

The application class to use.

Signature

returns　Class: The Presently application class.

Implementation

def application
	Presently::Application
end

`def middleware`

Build the middleware stack with Presently's public assets.

Signature

returns　Protocol::HTTP::Middleware: The complete middleware stack.

Implementation

def middleware
	application = self.application
	slides_root = self.slides_root
	templates_roots = self.templates_roots
	root = self.root
	
	::Protocol::HTTP::Middleware.build do |builder|
		# Serve assets from the user's public directory:
		builder.use Lively::Assets, root: File.expand_path("public", root)
		
		# Serve Presently's bundled assets (CSS, JS, components, etc.):
		builder.use Lively::Assets, root: File.expand_path("../../../public", __dir__)
		
		# Serve Lively's built-in assets (Live.js, morphdom, etc.):
		builder.use Lively::Assets, root: File.expand_path("public", Gem.loaded_specs["lively"].full_gem_path)
		
		builder.use application,
			slides_root: slides_root,
			templates_roots: templates_roots
	end
