activate [--shared|--temp] [path]
Activate the environment at the given path, or the home project environment if no path is specified. The active environment is the
environment that is modified by executing package commands. When the option --shared is given, path will be assumed to be a directory
name and searched for in the environments folders of the depots in the depot stack. In case no such environment exists in any of the
depots, it will be placed in the first depot of the stack. Use the temp option to create temporary environments. This should be useful
for experimenting with packages.
Highlighted:
or the home project environment if no path is specified
home project is not the current path.
