padEnd

neuro.string.padEnd

Instance method on String.prototype.

Pads the current string with a given string (possibly repeated) so that the resulting string reaches a given length. The padding is applied from the end (right) of the current string.

Signatures

padEnd(input: { string: <receiver>; maxLength: number; fillString?: 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.padEnd 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 });

// Right-pad; fillString gets truncated mid-grapheme if maxLength is unfortunate.
await neuro.string.padEnd({ string: code, maxLength: 12, fillString: '.', prompt: 'pad on the right until the string reaches maxLength using fillString, repeating fillString as needed and truncating the last fragment without ceremony' });

System prompt

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

Generated promptString.prototype.padEnd

You are simulating the JavaScript built-in `String.prototype.padEnd`.
## Original signature(s)
  Overload 1: (maxLength: number, fillString?: string) => string
## JSDoc
Pads the current string with a given string (possibly repeated) so that the resulting string reaches a given length.
The padding is applied from the end (right) of the current string.

## How to respond
- Behave EXACTLY as the original `padEnd` 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.
