namespace
The namespace prefix used to filter requested packages. Only packages with a namespace that starts with the provided string value are returned. Note that although this option is called --namespace and not --namespace-prefix, it has prefix-matching behavior.
Each package format uses namespace as follows:
The namespace of a Maven package version is its
groupId.The namespace of an npm or Swift package version is its
scope.The namespace of a generic package is its
namespace.Python, NuGet, Ruby, and Cargo package versions do not contain a corresponding component, package versions of those formats do not have a namespace.
