Constructor Details

#initialize(options = {}) {|?| ... } ⇒ Gem

Sets up tasks based on INVENTORY and SPECIFICATION, optionally yields the task object and the gem specification for further customization, then #defines the tasks.

The default for SPECIFICATION is to use the name, version, authors, email, homepage, licenses, and files of the inventory, use all of ‘README` as the description, set the summary to the first sentence of the description, set the require paths to “lib”, add each extension of the inventory’s extconf to the extensions, and finally add inventory’s dependencies.

Parameters:

  • options (Hash) (defaults to: {})

Options Hash (options):

  • :inventory (Inventory) — default: Inventory::Rake::Tasks.inventory —

    The inventory to use

  • :specification (Gem::Specification) —

    The specification to use

Yields:

  • (?)

Yield Parameters:

  • task (self)
  • specification (Gem::Specification)
