end

.find_resource(resource_type, path, cur_path = nil, owner_classes = nil, search_paths = []) ⇒ Resource

Returns the full path of a resource.

Spider provides the following resources:

  • :views (:filetypes => [‘.shtml’])

  • :js and :css (:path => ‘public’)

Apps can define their own resource types (see register_resource_type).

This method will look for the resource in the runtime root first, than in the app’s :“#resource_type_path”, and finally in the spider’s gem folder.

For example:

find_resource(:views, ‘abc/my_view’, nil, [MyApp]) will look into:

  • /home/views/my_app/abc/my_view.shtml

  • /home/views/apps/my_app/views/abc/my_view.shtml

  • /lib/spider/views/abc/my_view.shtml

Parameters:

  • resource_type (Symbol)
  • path (String)
  • cur_path (String) (defaults to: nil) —

    Current path: if set, will be used to resolve relative paths

  • owner_classes (Array) (defaults to: nil) —

    An Array of Classes, which must respond to .app (i.e., they must belong to an App). If set, will be used to determine the apps to look into.

  • search_paths (Array) (defaults to: []) —

    An Array of additional paths to look inside

Returns:

.main_process_startup ⇒ Object

This happens, for example, when Spider server is started from command line; the main process can then spawn other processes, as supporting listeners or workers.

Note that in some environments (e.g. Phusion Passenger) there will not be a main process, so this method will not be called.

.register_resource_type(name, options = {}) ⇒ void

This method returns an undefined value.

Adds a resource type name must be a symbol, extensions an array of extensions (strings, without the dot) for this resource.

Resources can be searched with find_resource. They will be searched first inside the home, then inside the app’s folder. This way, home can override app resources. See also find_resource.

Options may be:

  • :extensions an Array of possible extensions. If given, find_resource will try appending the extensions

    when looking for the file.

  • :path the path of the resource relative to resource root; if not given, name will be used.

Parameters:

  • name (Symbol)
  • options (Hash) (defaults to: {})
