Internal: Returns all registered loggers.
# File lib/gallus/repository.rb, line 10 def self.all @all ||= {} end
delete_with_children(name)

Internal: For testing purposes we need to be able to delete logger alongside with all its children.
# File lib/gallus/repository.rb, line 30 def self.delete_with_children(name) @mutex.synchronize do all.keys.each { |k| all.delete(k) if k.start_with?(name + PARENT_DELIMITER) } all.delete(name) end end
find_parent(name)

Internal: There must be a way to find parent logger for given class name. For example, looking up parent for Foo::Bar::Baz logger it’ll look up for Foo::Bar, then falling back to Foo and eventually to root logger if nothing found.
# File lib/gallus/repository.rb, line 17 def self.find_parent(name) parent, name = nil, name.dup while parent.nil? name = name.split(PARENT_DELIMITER)[0..-2].join(PARENT_DELIMITER) parent = all[name] break if name.empty? end parent end
get_or_create_logger(name) { |log| ... }

Internal: We obviously need a way to create logger or retrieve it by name if already registered. Creation of logger causes configuration to be inherited from parent (or root) logger.
# File lib/gallus/repository.rb, line 39 def self.get_or_create_logger(name, &block) name, log = name.to_s, nil @mutex.synchronize do if log = all[name] yield log if block_given? else all[name] = (log = Class.new(Log).new(find_parent(name), name, &block)) end end log end
