@tiptap/pm 3.11.0: NodeSelection

Échantillon vérifié pour npm @tiptap/pm 3.11.0: NodeSelection. Le contrat s'est exécuté sur node 22 · linux debian/x64 · docker et a réussi.

sha256:eba35781302042224c7493fa31c1d06522468297dfddc8576f4a68577364e017

Ce réseau offre une seule chose : un échantillon qui compile. Il l'a exécuté dans un bac à sable et conservé le reçu signé. Il ne note rien et ne garantit rien : si le même code compile chez vous, il ne l'a pas mesuré. Combien de clés de signature distinctes ont déposé un reçu de contrat réussi. Une seule, c'est l'auteur ; plus d'une signifie que quelqu'un d'autre l'a compilé aussi. Une clé est auto-générée sans identité enregistrée derrière, donc on compte des clés, pas des personnes. MIT-0

Preuves d'exécution

Contrat

  1. NodeSelection.create selects an immediate node and determines from and to boundaries
  2. NodeSelection.isSelectable identifies whether a node can be selected as a node
  3. NodeSelection.content extracts a Slice containing the selected node
  4. NodeSelection.map preserves node selection position across document transformations
  5. NodeSelection.toJSON and NodeSelection.fromJSON serialize and restore node selections
  6. NodeSelection integrates with EditorState transactions to select and replace nodes
  7. NodeSelection.create throws RangeError when given an out-of-range position

Clean-room public code sample — generation instructions

Write a brand-new, minimal, self-contained code sample in this clean-room directory.
Do not copy, paraphrase, or reference any existing project source. Work only from this spec.

A csx.json manifest scaffold already exists. Do not recreate it from memory. Preserve its case.goal, packages and symbols; fill its empty case.contract with exact assertions and correct its environment, commands and verifierAdapter for the files you generate.

Goal: verify @tiptap/pm.NodeSelection in pkg:npm/%40tiptap/pm@3.11.0
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40tiptap/pm@3.11.0
Demonstrate these symbols/APIs:
  - @tiptap/pm.NodeSelection

Rules:
  - One focused purpose; the smallest project that proves the goal.
  - Include a contract test (test/contract.*) that runs OFFLINE and exits 0 exactly when the goal behavior works.
  - Pin every dependency with a lockfile so resolution is reproducible.
  - No secrets, credentials, or tokens. No real URLs (only example.com or localhost). No absolute paths.
  - No personal names, emails, company names, or project identifiers of any kind.
  - No binaries and no generated output (node_modules, dist, target, venv, .git, .env).
  - Keep it under 200 files and 256KB packed.
