Module: Coradoc::CoreModel::InlineContent

Defined in:
lib/coradoc/core_model/inline_content.rb

Overview

Operations on mixed arrays of inline content (String / InlineElement / CoreModel::Base). Single source of truth for text extraction and edge cleanup, replacing parallel implementations that previously lived in the HTML converters.

No method here mutates its inputs — InlineElements are duplicated via #with_content, Strings are replaced with new instances.

Class Method Details

.strip_edges(content) ⇒ Object

Return a new array with leading whitespace stripped from the first text-carrying item and trailing whitespace stripped from the last. Inputs are not mutated. Non-Array inputs return unchanged. If no item carries text, returns the input array unchanged.

def strip_edges(content)
  return content unless content.is_a?(Array)
  return content if content.empty?

  first_idx = content.index { |i| text_carrier?(i) }
  return content if first_idx.nil?
  last_idx = content.rindex { |i| text_carrier?(i) }

  content.map.with_index do |item, idx|
    next item unless text_carrier?(item)

    stripped = item_text(item)
    stripped = stripped.lstrip if idx == first_idx
    stripped = stripped.rstrip if idx == last_idx
    item.is_a?(String) ? stripped : item.with_content(stripped)
  end
end

.text_of(content) ⇒ Object

Extract plain text from a mixed content value.

nil → ” / String → itself / Array → text_of mapped + joined / InlineElement → #content.to_s / StructuralElement → recurse on #children / other Base → #content if String else #title.to_s / anything else → #to_s.
