replaceAll

neuro.string.replaceAll

Instance method on String.prototype.

Replace all instances of a substring in a string, using a regular expression or search string.

Signatures

replaceAll(input: { string: <receiver>; searchValue: string | RegExp; replaceValue: string; prompt?: string }): Promise<string>
replaceAll(input: { string: <receiver>; searchValue: string | RegExp; replacer?: (substring: string; args: any[]) => string; prompt?: string }): Promise<string>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native String.prototype.replaceAll and returns a resolved Promise without contacting the LLM. When present, the LLM is given the original arguments plus your prompt and is asked to behave like the original method.

Example

import { configureClient, neuro } from 'neuro-ts';

configureClient({ apiKey: process.env.OPENAI_API_KEY });

// All-match replace; non-global regex throws here, unlike match which silently does the wrong thing.
await neuro.string.replaceAll({ string: doc, searchValue: 'legacy', replaceValue: 'classic', prompt: 'replace every searchValue match with replaceValue, throwing if searchValue is a non-global regex, the friendly error we wished match had' });

System prompt

The exact system prompt the SDK sends to your model when you provide a prompt field:

Generated promptString.prototype.replaceAll

You are simulating the JavaScript built-in `String.prototype.replaceAll`.
## Original signature(s)
  Overload 1: (searchValue: string | RegExp, replaceValue: string) => string
  Overload 2: (searchValue: string | RegExp, replacer?: (substring: string, ...args: any[]) => string) => string
## JSDoc
Replace all instances of a substring in a string, using a regular expression or search string.

## How to respond
- Behave EXACTLY as the original `replaceAll` would, but use the user's intent to choose any callback / comparator / transform logic that the original would normally accept as an argument.
- Strictly preserve the original return type and shape.
- Output ONLY the JSON-encoded return value of the function call.
- Do NOT include explanations, prose, comments, or markdown fences.
- If the function would return `undefined`, output the literal string `undefined`.
- For Date / RegExp / Map / Set / TypedArray returns, output an object of the form { "__type": "Date" | "RegExp" | "Map" | "Set" | "<TypedArrayName>", ... } so the SDK can rehydrate it.
