Module: Capybara::Simulated::WhitespaceNormalizer

Included in:
Node
Defined in:
lib/capybara/simulated/whitespace_normalizer.rb

Overview

Capybara::Node::WhitespaceNormalizer was extracted in capybara 3.40 — Forem (and other apps that pin ~> 3.37) still ship the older release where the module doesn't exist. Inline copies of normalize_spacing / normalize_visible_spacing keep the gem working against the whole 3.37+ range; they're stable text- processing helpers, no behavioural drift to worry about.
