import click


# A datatype for the --from-json parameter. This is just a string (and so we report it is a text type in click) and will
# pass through any value given to it (in this sense it behaves like click's UNPROCESSED type).
#
# The only special behaviour it has is to store metadata information provided at construction time so it can be used when
# parsing data (either a command line string or input from a file) given by a caller.
#
# We need to decorate against the type because when the --from-json parameter is evaluated the metadata information from
# @json_skeleton_utils.json_skeleton_generation_handler is not yet available. The --from-json
# parameter is eager evaluated and is also evaluated before the actual Python function for the click command is called,
# and the information from @json_skeleton_utils.json_skeleton_generation_handler is only available once the command is called
