Standard Libraries

AdeshLang ships a set of builtin libraries — namespaces that are compiled directly into the runtime and available in every program without downloading anything. They provide high-performance, ready-to-use functionality for numeric math, complex numbers, random numbers, file access, JSON, HTTP, concurrency, and more.

Unlike modules you write yourself or pull from a package registry, builtin libraries:

• Are always available — no external files, manifests, or network access required.
• Are case-insensitive to import and resolve to the registered namespace (import Math and import math both work).
• Are implemented natively (in Rust) for speed, with the same behavior across every backend (Interpreter, Bytecode VM, JIT, Native JIT, AOT, WebAssembly, GPU/MLIR).

How to use a builtin library

Builtin libraries are used through the import statement. The import binds the library's namespace under a name you can call methods on.

import Math;     // real-number math
import cmath;    // complex-number math

print(Math.sqrt(16.0));   // 4.0
print(cmath.sqrt(-4.0));  // 0.0 + 2.0j

You can also import individual members:

import { sqrt, pow } from "Math";
print(sqrt(25.0));  // 5.0

tip

Every builtin library follows the same mental model: import the namespace, then call Namespace.method(...). Constants are exposed as namespace properties such as Math.PI.
