Standard Library

The current Radon repository ships these modules in stdlib/:

stdlib/
+-- argparser.rn
+-- array.rn
+-- colorlib.rn
+-- io.rn
+-- math.rn
+-- os.rn
+-- radiation.rn
+-- string.rn
+-- system.rn
+-- universe.rn
+-- winlib.rn

Module Overview

• argparser provides a command-line parser implemented in Radon.
• array [Legacy] — Array methods are now built-in. This module is kept for backwards compatibility.
• colorlib provides ANSI color and text-style helpers.
• io provides Input and Output helpers, including password input.
• math provides constants and functions such as PI, sqrt, pow, factorial, and sin.
• os exposes filesystem and path helpers through the Python bridge.
• radiation defines reusable error constructors such as ValueError and TypeError.
• string [Legacy] — String methods are now built-in. This module is kept for backwards compatibility.
• system exposes basic system information.
• universe is a small example-style module included with the distribution.
• winlib exists as a placeholder Windows-specific module.

Built-in Primitive Methods

As of the latest release, all primitive types (Array, String, Number, Boolean, HashMap) have methods available via dot notation without any imports. See Data Types for the complete reference.

Importing Modules

Import a whole module:

import io

var name = io.Input.get_string("Name: ")
print(name)

Import selected names:

from os import path
from io import Output as Out

print(path)
Out.write("Radon")

Notes

Several standard library modules use pyapi() internally. That means filesystem, platform, or Python-hosted behavior may trigger Radon's runtime permission prompts.
