Module: TranslationDiff::Leaves

Defined in:
lib/translation_diff/leaves.rb

Overview

The two things this pipeline has always promised about a caller's structure that Document deliberately does not: a nested nil comes back as the empty string, and the size of a document is every leaf in it, translatable or not.

Class Method Summary collapse

Class Method Details

.collapse_nils(node) ⇒ Object

Document hands every non-String leaf straight back, which is the honest behaviour for a general structural map. Answering a nested nil with "" is the pipeline's own promise, so it is made here rather than there.

def self.collapse_nils(node)
  case node
  when Hash then node.to_h { |key, value| [key, collapse_nils(value)] }
  when Array then node.map { |value| collapse_nils(value) }
  when nil then ""
  else node
  end
end

.count(node) ⇒ Object

Every leaf the caller wrote, whatever its type: the number a translate payload reports as values.
