yarlo-region-markdown

Parse and serialize Yarlo “region markdown”: YAML frontmatter plus HTML comment regions (#region / #endregion) and inline <!-- [path]|pipes --> markers with chained pipes (list, json, slug, etc.).

API

• parseRegionMarkdown(input, options?) — Returns { frontmatter, data, warnings, operations? }.
• stringifyRegionMarkdown({ frontmatter?, leadingMarkdown?, regions, trailingMarkdown? }) — Builds a .md string.
• formatRegionBlock(path, mode, pipes?, content) — One region block.
• registerPipe(name, handler) — Extend the built-in pipe registry.
• scanAllOperations(body) / applyPipeChain(raw, pipes, opts) — Lower-level building blocks.
