module Alf

#
# Specialization of the Reader contract for .alf files.
#
# A .alf file simply contains a query expression in the Lispy DSL. This
# reader decodes and compiles the expression and delegates the enumeration
# to the obtained operator.
#
# Note that an Environment must be wired at creation time. A
# NoSuchDatasetError will certainly occur otherwise.
#
class AlfFile < Reader
# (see Reader#each)
def each
op = Alf.lispy(environment).compile(input_text, input_path)
op.each(&Proc.new)
end
Reader.register(:alf, [".alf"], self)
end # module AlfFile
end # class Reader
