Look in the active project for a UUID if it is not given.

[fredrikekre]

This makes top-level usage of @get_scratch! look in the active project for a UUID to use before falling back to the global namespace.

For a motivating example: Typically when you work on a package you have that package activated. In such a case it is very convenient if code running in the REPL behaves similar to how it works inside the package, in particular @get_scratch! will now return a path with the package UUID instead of the global namespace:

julia> using Scratch

julia> Base.active_project()
"/home/fredrik/dev/Scratch/Project.toml"

julia> @get_scratch!("hello-world")
"/home/fredrik/.julia/scratchspaces/6c6a2e73-6563-6170-7368-637461726353/hello-world"

For a package environment without a UUID this patch does not change anything.
