Move each util from utils.ts into its own file under utils/, one
utility per file, and re-export them from index.ts so the public API
of @tiptap/markdown stays unchanged.

📝 Walkthrough

Summary

  • Split Markdown utilities from utils.ts into separate files.
  • Updated internal imports to use the new utility files.
  • Re-exported all utilities from index.ts.
  • Removed the old utils.ts file.
  • Fixed wrapInMarkdownBlock for multi-character prefixes and trailing blank lines.
  • Added tests for wrapInMarkdownBlock.

Walkthrough

The markdown package replaces its consolidated utility module with individual utility files. Internal imports and public exports now reference those modules directly. Tests and a changeset cover wrapInMarkdownBlock.

Changes

Markdown utility module split

Layer / File(s) Summary
Content and token utilities
packages/markdown/src/utils/assumeContentType.ts, packages/markdown/src/utils/extractAbsorbedBlankLines.ts, packages/markdown/src/utils/isTaskItem.ts, packages/markdown/src/utils/wrapInMarkdownBlock.ts, packages/markdown/__tests__/utilities.spec.ts, .changeset/2026-08-15-markdown-wrap-in-markdown-block.md
Content type inference, blank-line extraction, task-item detection, and Markdown block wrapping now use separate modules. Tests cover prefixes, blank lines, and trailing output.
Mark lifecycle utilities
packages/markdown/src/utils/findMarksToClose.ts, packages/markdown/src/utils/findMarksToCloseAtEnd.ts, packages/markdown/src/utils/findMarksToOpen.ts, packages/markdown/src/utils/closeMarksBeforeNode.ts, packages/markdown/src/utils/reopenMarksAfterNode.ts
Mark comparison, closing, and reopening logic now use separate modules. Attribute differences remain part of mark matching.
Import and export integration
packages/markdown/src/Extension.ts, packages/markdown/src/MarkdownManager.ts, packages/markdown/src/index.ts
Internal imports use individual utility paths. The package entry point explicitly re-exports the utility modules.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 0fb66

This change only reorganizes markdown utilities into separate files without a demonstrated behavior or production-impact risk; no actionable merge-blocking risk remains beyond normal checks and review.

remove the final output.slice call so multi-character prefixes are preserved
exactly.

Insert blank lines only between content lines instead of trimming a
single trailing character, which corrupted prefixes longer than one
character and leaked a trailing newline.
