Defined in:

lib/activerecord_callback_lens/renderer/html_renderer.rb

Overview

Renders a single ConditionTree node (and its descendants) as nested <ul> markup, and exposes the flat list of leaf condition names. Extracted from HtmlRenderer so the recursive tree handling is a single, testable responsibility separate from page assembly.

All names are HTML escaped via CGI.escapeHTML so values containing <, > or & cannot break the surrounding markup.

Constant Summary

Tree =

Parser::ConditionTree
