Extract the backtrace stripping off the leading semantic logger entries. Leaves all other system and gem path entries in place.
# File lib/semantic_logger/utils.rb, line 37 def self.extract_backtrace(stack = caller) while (first = stack.first) && extract_path?(first) stack.shift end stack end
Whether this path should be excluded from any cleansed backtrace
# File lib/semantic_logger/utils.rb, line 49 def self.extract_path?(path) extract_paths.any? { |exclude| path.include?(exclude) } end
# File lib/semantic_logger/utils.rb, line 44 def self.extract_paths @extract_paths ||= %w[lib/semantic_logger lib/rails_semantic_logger] end
Returns the visibility for an instance method
# File lib/semantic_logger/utils.rb, line 24 def self.method_visibility(mod, method_name) method_name = method_name.to_sym if mod.instance_methods.include?(method_name) :public elsif mod.private_instance_methods.include?(method_name) :private elsif mod.protected_instance_methods.include?(method_name) :protected end end
Try to strip everything off of the supplied backtrace, until the first application stack entry is at the top. For example all leading gem paths and built-in ruby code paths are removed from the top. Once the first application entry is found, the remaining stack is returned.
# File lib/semantic_logger/utils.rb, line 56 def self.strip_backtrace(stack = caller) while (first = stack.first) && (strip_path?(first) || extract_path?(first)) stack.shift end stack end
Whether this path should be excluded from any cleansed backtrace
# File lib/semantic_logger/utils.rb, line 75 def self.strip_path?(path) strip_paths.any? { |exclude| path.start_with?(exclude) } end
Paths to exclude in the stripped backtrace Includes Gems and built-in Ruby code paths
# File lib/semantic_logger/utils.rb, line 65 def self.strip_paths @strip_paths ||= begin paths = Gem.path | [Gem.default_dir] paths << RbConfig::CONFIG["rubylibdir"] paths end end
