v0.2.0

What's Changed

⚠️ Breaking Changes

The migration API was redesigned around structured result types (#30). UPGRADING.md has before/after examples for every change.

• parse_* methods now return a Parse and *_to_markdown / convert return a Conversion instead of raw Strings — use Conversion#markdown (or #to_s) for the output (#30)
• Global configuration is gone: Markbridge::Configuration, .configure, .reset_defaults!, and all default_* accessors were removed — build a reusable renderer with Markbridge.discourse_renderer(...) and pass it via renderer: (#30)
• tags:, tag_library:, escaper:, and escape_hard_line_breaks: were removed from the per-call signatures; *_to_markdown / convert accept only handlers:, renderer:, and raise_on_error: (#30)
• Proc/lambda handlers are no longer supported — handlers must be objects responding to #process(...) (#30)
• MediaWiki parser kwarg renamed: inline_tag_registry: → handlers: (#30)
• TextFormatter handlers must accept a processor: keyword (#30)

✨ Features

• Markbridge.discourse_renderer(...) factory builds reusable Renderer instances — accepts tags:, tag_library:, unregister:, escaper:, escape:, escape_hard_line_breaks:, allow:, postprocessor:, strip_trailing_invisibles: (#30)
• Markbridge.convert(format:) dispatcher and polymorphic Markbridge.render(Parse | AST::Node) (#30)
• AST mutation between parse and render: block form on every *_to_markdown / convert, plus AST::Element#each_descendant, #descendants(klass = nil), and #replace_child(old, new) (#30)
• raise_on_error: false collects render errors on Conversion#errors for per-row failure isolation in batch migrations (#30)
• Selective Markdown escaping via MarkdownEscaper#allow: (:bullet_list, :ordered_list, :atx_heading, :block_quote, alias :lists), and IdentityEscaper / discourse_renderer(escape: false) for already-trusted Markdown (#30)
• Handler registries gain #overlay(name) { |previous| ... } for wrapping default handlers (BBCode, HTML, TextFormatter) (#30)
• TagLibrary#unregister — unregistered AST classes auto-pass-through to their rendered children (#30)
• HTML and TextFormatter parsers accept pre-parsed Nokogiri input (DocumentFragment, Document, Element) in addition to Strings (#30)
• AST::Details + DetailsTag for Discourse [details=…]…[/details] collapsible sections (#30)
• Optional strip_trailing_invisibles config flag (#39)
• Collapse whitespace in HTML per spec (#36)
• Map inline span styles to AST formatting nodes (#34)

🐛 Bug Fixes

• Make RenderContext parent-queries answer is_a? semantics (#42)
• Move ] label-escape into MarkdownEscaper so image-in-link works (#41)
• Escape ] in link labels to prevent early link termination (#40)
• Insert blank line between raw text and following block elements (#37)
• Skip [u] wrapper inside [url] and [email] (#36)
• Skip [u] wrapper when underline content is whitespace-only (#35)
• Treat Unicode whitespace as whitespace in RenderingInterface#wrap_inline (#33)
