module Riffer::Helpers::Identifier - Riffer API Reference

Source

# File lib/riffer/helpers/identifier.rb, line 12
def derive(class_name)
  class_name.
    to_s.
    gsub("::", "/").
    gsub(/([A-Z]+)([A-Z][a-z])/, '\1_\2').
    gsub(/([a-z\d])([A-Z])/, '\1_\2').
    downcase
end

Derives a snake_case identifier from a class name string.

for (klass)

Source

# File lib/riffer/helpers/identifier.rb, line 28
def for(klass)
  cached = klass.instance_variable_get(:@derived_identifier) #: String?
  return cached if cached

  real_name = real_name(klass)
  return "" if real_name.nil?

  derived = derive(real_name)
  klass.instance_variable_set(:@derived_identifier, derived)
  derived
end

Derives and memoizes the identifier for a class or module. Anonymous classes return “” without caching, so a class named later still derives its real identifier — a guard that must travel with the cache, so callers never memoize their own.

real_name (klass)

Source

# File lib/riffer/helpers/identifier.rb, line 46
def real_name(klass)
  Module.instance_method(:name).bind_call(klass) #: String?
end

Returns the class-path name of a class or module, or nil when anonymous. Tool classes shadow Module#name with the identifier DSL, so the real name must come from Module’s own implementation.
