checker_for_syntax(_, syntax) click to toggle source

Finds the most significant checker for the given syntax (most significant is to the right). Returns nil if there is no registered checker.

   # File lib/puppet/pops/evaluator/external_syntax_support.rb
30 def checker_for_syntax(_, syntax)
31   checkers_hash = Puppet.lookup(:plugins)[Puppet::Plugins::SyntaxCheckers::SYNTAX_CHECKERS_KEY]
32   checkers_hash[lookup_keys_for_syntax(syntax).find {|x| checkers_hash[x] }]
33 end

Returns an array of possible syntax names

   # File lib/puppet/pops/evaluator/external_syntax_support.rb
36 def lookup_keys_for_syntax(syntax)
37   segments = syntax.split(/\+/)
38   result = []
39   loop do
40     result << segments.join("+")
41     segments.shift
42     break if segments.empty?
