Forked from https://github.com/simplabs/ember-promise-modals with specific changes for https://github.com/TryGhost/Admin.

Not recommended for general use, this package will be removed if upstream becomes compatible with our requirements.

Custom changes:

• added .finally() to modal instances so the Promise-like interface is more complete. Useful for cleanup after a modal is resolved/rejected without duplication
• added beforeClose() as an option that can be passed when opening a modal, if the function returns false then the modal close will be aborted
• dropped passthrough of focusTrapOptions.onDeactivate when closing modal as it causes @close return values to be lost
  • mainmatter#565
