ResourceFunction[resource]

represents the function associated with the specified resource.

ResourceFunction[resource,prop]

gives the specified property of the resource.

Details

  • ResourceFunction["name"] searches in order for a resource function with the specified name in the following locations:
  • locally in the session (for resource functions from DefineResourceFunction)
    at the locations specified by $PersistencePath
    in the Wolfram Function Repository
  • In ResourceFunction[resource], resource can have the following forms:
  • "name"function name, resolved as described
    ResourceObject[…]a resource object of type "Function" stored at any location
    CloudObject[…]a cloud object containing a function resource object
    LocalObject[…]a local object containing a function resource object
  • ResourceFunction[resource][args …] applies the function to the given arguments.
  • The available properties are given by ResourceFunction[resource,"Properties"] and typically include properties of the ResourceObject as well as:
  • "SymbolName"fully qualified string name of the underlying function
    "FunctionLocation"file, object or method used to store the definition
  • Function definitions in a function resource are typically not explicitly retrieved until the function is used.
  • When the definitions for a function resource are retrieved, they are usually cached in $LocalBase.
  • ResourceObject[ResourceFunction[…]] returns the resource object containing the given function.
  • ResourceFunction[ResourceFunction[…],prop] gives a property for an existing resource function.
  • CloudDeploy[ResourceFunction[…]] or CloudPublish[ResourceFunction[…]] saves a resource function in the cloud.
  • LocalCache[ResourceFunction[…]] saves a resource function as a LocalObject[…].
  • The following functions work on ResourceFunction objects: Attributes, Definition, DownValues, FullDefinition, Options and SymbolName.
  • New resource functions can be defined with DefineResourceFunction or with a definition notebook from File ▶ New ▶ Repository Item ▶ Function Repository Item.
