Module: Markbridge::Renderers::Discourse::HtmlBlockSafety

Defined in:
lib/markbridge/renderers/discourse/html_block_safety.rb

Overview

Decides whether a rendered fragment is safe to splice into a CommonMark HTML block (spec §4.6). Inside such a block the content passes through as raw HTML; Markdown is only parsed again across blank lines. Safe output is therefore: a raw HTML or plain-text fragment without Markdown sigils, or a \n\n…\n\n wrap — a deliberate Markdown island.

Used by the html_mode contract check that ships in markbridge/rspec and by this repo's own contract spec.
