# Converts params from double underscore notation to nested hash under 'config'
# Parameters starting GDC_ are considered system params and aren't converted.
#
# This is useful because the executor platform can currently
# do just key-value parameters. Also it makes it easier for
# a user, as there aren't as much curly braces.
#
#
# ### Examples
# If you pass params in form:
# {"my__namespace__param": "value"}
#
# you'll get:
# {"my": {"namespace": {"param": value}}}

params = params.to_hash
unless params['config']
# split the params to those starting with GDC and those that don't, put other params under config
gdc_params, other_params = params.partition { |k, _| k =~ /GDC_.*/ }.map { |h| Hash[h] }
params = gdc_params.merge('config' => other_params.undot)
