classify(dashed_word)

Given a word with dashes, returns a camel cased version of it.
classify(‘job-name’) # => ‘JobName’
# File lib/resque-loner/legacy_helpers.rb, line 45 def classify(dashed_word) dashed_word.split('-').each { |part| part[0] = part[0].chr.upcase }.join end
constantize(camel_cased_word)
click to toggle source
Tries to find a constant with the name specified in the argument string:
constantize(“Module”) # => Module constantize(“Test::Unit”) # => Test::Unit
The name is assumed to be the one of a top-level constant, no matter whether it starts with “::” or not. No lexical context is taken into account:
C = ‘outside’ module M
C = 'inside' C # => 'inside' constantize("C") # => 'outside', same as ::C
end
NameError is raised when the constant is unknown.
# File lib/resque-loner/legacy_helpers.rb, line 66 def constantize(camel_cased_word) camel_cased_word = camel_cased_word.to_s if camel_cased_word.include?('-') camel_cased_word = classify(camel_cased_word) end names = camel_cased_word.split('::') names.shift if names.empty? || names.first.empty? constant = Object names.each do |name| args = Module.method(:const_get).arity != 1 ? [false] : [] if constant.const_defined?(name, *args) constant = constant.const_get(name) else constant = constant.const_missing(name) end end constant end
