Concatenates the logic in the array of parse results into one parse result. @return Puppet::Parser::AST::BlockExpression
# File lib/puppet/pops/parser/code_merger.rb 7 def concatenate(parse_results) 8 # this is a bit brute force as the result is already 3x ast with wrapped 4x content 9 # this could be combined in a more elegant way, but it is only used to process a handful of files 10 # at the beginning of a puppet run. TODO: Revisit for Puppet 4x when there is no 3x ast at the top. 11 # PUP-5299, some sites have thousands of entries, and run out of stack when evaluating - the logic 12 # below maps the logic as flatly as possible. 13 # 14 children = parse_results.select {|x| !x.nil? && x.code}.reduce([]) do |memo, parsed_class| 15 case parsed_class.code 16 when Puppet::Parser::AST::BlockExpression 17 # the BlockExpression wraps a single 4x instruction that is most likely wrapped in a Factory 18 memo + parsed_class.code.children.map {|c| c.is_a?(Puppet::Pops::Model::Factory) ? c.model : c } 19 when Puppet::Pops::Model::Factory 20 # If it is a 4x instruction wrapped in a Factory 21 memo + parsed_class.code.model 22 else 23 # It is the instruction directly 24 memo << parsed_class.code 25 end 26 end 27 Puppet::Parser::AST::BlockExpression.new(:children => children) 28 end
