Quill Parity Notes

Copy Markdown View Source

DeltaHtml aims for practical parity with Quill semantic output, while keeping server-side behavior explicit and configurable.

Matches

  • Common inline formats (bold, italic, underline, strike, code)
  • Headers and blockquotes
  • Ordered/bullet/checklist lists
  • Direction/alignment/indent handling
  • Link attributes including rel="noopener noreferrer" and target="_blank"

Intentional Differences

  • quill_css: true prefers class output for align/direction, while Quill semantic HTML often uses inline styles for those attributes.
  • Unsupported embeds are dropped instead of attempting partial rendering.
  • Default mode (:quill) keeps Quill-compatible scheme behavior.
  • Strict mode (:strict) intentionally diverges to allow tighter policies.

Validation Strategy

The project includes a Quill harness (quill_harness/) and parity tests. Use:

mix quill.setup
mix test

to compare semantic output behavior across supported fixtures.
