module Scimitar
# Namespace containing various chunks of Scimitar support code that don't
# logically fit into other areas.
#
module Support
# A namespace that contains various stand-alone utility methods which act
# as helpers for other parts of the code base, without risking namespace
# pollution by e.g. being part of a module loaded into a client class.
#
module Utilities
# Takes an array of components that usually come from a dotted path such
# as <tt>foo.bar.baz</tt>, along with a value that is found at the end of
# that path, then converts it into a nested Hash with each level of the
# Hash corresponding to a step along the path.
#
# This was written to help with edge case SCIM uses where (most often, at
# least) inbound calls use a dotted notation where nested values are more
# commonly accepted; converting to nesting makes it easier for subsequent
# processing code, which needs only handle nested Hash data.
#
# As an example, passing:
#
# ['foo', 'bar', 'baz'], 'value'
#
# ...yields:
#
# {'foo' => {'bar' => {'baz' => 'value'}}}
#
# Parameters:
#
# +array+:: Array containing path components, usually acquired from a
# string with dot separators and a call to String#split.
#
# +value+:: The value found at the path indicated by +array+.
#
# If +array+ is empty, +value+ is returned directly, with no nesting
# Hash wrapping it.
#
def self.dot_path(array, value)
return value if array.empty?
{}.tap do | hash |
hash[array.shift()] = self.dot_path(array, value)
end
