Standard Library

The Arden Standard Library (std) provides core functionality for building applications.

Modules

• Math: Mathematical functions and constants.
• Str: String manipulation utilities.
• Time: Time retrieval and sleeping.
• File: File system operations.
• System: System-level interactions (exit, getenv, etc.).
• Args: Command-line arguments.
• Collections: Built-in List and Map types.
• I/O: Console input and output.

Import Behavior (Important)

The stdlib is implemented as compiler intrinsics, but import behavior is split:

• print, println, and read_line are free functions in std.io and should be imported:
  • import std.io.*; (or specific function imports).
• Module-style APIs such as Math.*, Str.*, Time.*, System.*, File.*, and Args.* are intrinsic objects and are available directly in the current compiler.
• Builtins like to_string, range, exit, and assertion helpers (assert*, fail) are available without import.
• Those builtins can also be stored in typed function values, for example conv: (Integer) -> Float = to_float, build: (Integer, Integer) -> Range<Integer> = range, check: (Integer, Integer) -> None = assert_eq, stop: (Integer) -> None = exit, and fail_now: () -> None = fail.
• Direct stdlib object members can be stored as typed function values too, for example cwd: () -> String = System.cwd, sleep_ms: (Integer) -> None = Time.sleep, argc: () -> Integer = Args.count, and rand: () -> Float = Math.random.

There are no external .arden stdlib source files; calls are lowered directly by the compiler/codegen pipeline.
