Details

  • PacletSymbol is a convenient shorthand that installs the paclet if necessary, calls Needs on its primary context and evaluates to the named symbol.
  • PacletSymbol loads the primary context of the paclet in a way that does not modify $ContextPath.
  • For paclets that are not already installed, the paclet is downloaded and loaded in the current session but not installed for future sessions.
  • PacletSymbol is a way to sample a paclet's functionality without permanently installing it or adding its context to the context path.
  • The paclet argument can have any of the following forms:
  • "name"name of the paclet or ResourceObject
    PacletObject[…]a paclet object
    ResourceObject[…]a resource object of type "Paclet"
    File[…]a paclet in a given directory
  • PacletSymbol accepts the same options as ResourceObject.
