@jhl548/duplicate-doc-core

@jhl548/duplicate-doc-core provides framework-independent types and helpers for duplicate document highlighting.

Features

• Shared document, range, duplicate point, and editor snapshot types.
• Similarity-based highlight color and CSS class helpers.
• Range normalization and document filtering utilities.
• Plain-text highlight resolution helpers for checking whether a range can still render after edits.
• Tiptap duplicate highlight extension.
• Shared highlight styles via @jhl548/duplicate-doc-core/style.css.

Install

npm install @jhl548/duplicate-doc-core

Usage

import {
  DuplicateHighlightExtension,
  filterHighlightsForDocument,
  type DuplicateHighlight,
  type NormalizedDocument
} from "@jhl548/duplicate-doc-core";
import { hasResolvableHighlightInPlainText } from "@jhl548/duplicate-doc-core/highlight-resolution";
import "@jhl548/duplicate-doc-core/style.css";

This package is intended to be consumed directly by framework adapters such as @jhl548/duplicate-doc-vue, or by applications that need access to the shared duplicate document model.

Use hasResolvableHighlightInPlainText(plainText, highlight) from the pure highlight-resolution subpath before switching documents when the app needs to know whether at least one highlight range can still be resolved in the current edited text.
