expand_runtime_values(hash)

Ensure keys are strings and expand any values in a hash that are Proc's by calling them and replacing the value with the result. This allows setting global tags with runtime values.
# File lib/lumberjack/tags.rb, line 25 def expand_runtime_values(hash) return nil if hash.nil? if hash.all? { |key, value| key.is_a?(String) && !value.is_a?(Proc) } return hash end copy = {} hash.each do |key, value| if value.is_a?(Proc) && (value.arity == 0 || value.arity == -1) value = value.call end copy[key.to_s] = value end copy end
stringify_keys(hash)

Transform hash keys to strings. This method exists for optimization and backward compatibility. If a hash already has string keys, it will be returned as is.
# File lib/lumberjack/tags.rb, line 8 def stringify_keys(hash) return nil if hash.nil? if hash.keys.all? { |key| key.is_a?(String) } hash elsif hash.respond_to?(:transform_keys) hash.transform_keys(&:to_s) else copy = {} hash.each do |key, value| copy[key.to_s] = value end copy end end
