API

Cask has an extensive API, which is briefly described in this document. For full documentation of each function, read the function doc-string.

As you will see, almost every API function takes a bundle as first argument. A bundle is an object that describes the current Cask project. You should not modify this object directly, but use the API functions to do so.

To create a bundle object, use either cask-setup or cask-initialize, which are described below.

Documentation and Examples

cask-initialize (&optional project-path)
