PineTS Input (input) Namespace

This directory contains the implementation of Pine Script’s input.* namespace functions. These functions handle user inputs/parameters for indicators.

Architecture

Functions are factory functions accessing the context.

The param() Method

The input.param() method returns the value wrapped in a single-element array: [val].

return [val];

Purpose

This wrapping might be a historical artifact or used to distinguish input values from standard scalar values in the Context.init() logic, similar to how tuple returns are wrapped in double brackets.

Implementation Specifics

1. Constant Nature

In Pine Script, input values are constant throughout the script execution (except for input.source or input.price which might vary if mapped to changing data).

2. Types

Functions like input.int, input.float, input.bool perform validation or casting to ensure the provided value matches the expected type.

Generating the Barrel File

To regenerate the input.index.ts file:

npm run generate:input-index
