Dieses Netzwerk bietet eine Sache: ein Sample, das baut. Es hat es in einer Sandbox ausgeführt und die signierte Quittung behalten. Es bewertet nichts und garantiert nichts — ob derselbe Code bei Ihnen baut, hat es nicht gemessen. Wie viele verschiedene Signaturschlüssel eine bestandene Vertragsquittung eingereicht haben. Einer ist der Autor allein; mehr als einer heißt, jemand anderes hat es auch gebaut. Ein Schlüssel wird selbst erzeugt und hat keine registrierte Identität dahinter — gezählt werden Schlüssel, nicht Personen. MIT-0

Contract

  1. Plugin default export is a function factory declaring Babel version compatibility
  2. Plugin factory returns an object named transform-duplicate-named-capturing-groups-regex with manipulateOptions, pre, and visitor.RegExpLiteral
  3. Plugin factory throws an Error when runtime option is non-boolean
  4. Plugin pre() sets duplicateNamedCaptureGroups feature flag and runtime options on Babel file context
  5. RegExpLiteral visitor compiles duplicate named capturing groups to numbered groups and wraps with wrapRegExp helper when runtime is true
  6. RegExpLiteral visitor compiles duplicate named capturing groups without wrapRegExp when runtime is false
  7. RegExpLiteral visitor skips wrapRegExp helper wrapping when RegExp is used in a test method expression
  8. RegExpLiteral visitor leaves regular expressions without duplicate named groups unchanged

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 @babel/plugin-transform-duplicate-named-capturing-groups-regex.default in pkg:npm/%40babel/plugin-transform-duplicate-named-capturing-groups-regex@7.29.7
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40babel/plugin-transform-duplicate-named-capturing-groups-regex@7.29.7
Demonstrate these symbols/APIs:
  - @babel/plugin-transform-duplicate-named-capturing-groups-regex.default
Constraints:
  - executionContext: node
Required runtime conditions:
  - ecosystem: npm
  - language: javascript
  - moduleSystem: esm
  - packageManager: npm@10.9.8
  - runtime: node@22.23.2

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.
