Standard Library Overview

Everything lives under the global std object. The namespace is flat: std.string, std.sort, std.math, and so on are direct members of std (there is no std.algo or std.os nesting). All of it is restricted (read-only) — scripts can call it but never modify it.

std.math.abs(-42)
std.string.upper("hi")
std.file.read("a.txt")

The std surface

Module / function	Purpose
std.string	String manipulation
std.sort	Array algorithms (map, filter, sort, ...)
std.seq	Sequence helpers (range, chunk, take, drop, sets)
std.math	Math functions and constants
std.convert	Number/string/base conversion, format
std.hash	md5, sha256, crc32
std.crypto	AES encrypt/decrypt, file crypto, random bytes (OpenSSL)
std.json	parse / stringify
std.compression	zstd / lz4 compress & decompress (optional at build)
std.image	PNG / JPEG / BMP load, save, convert
std.uuid	uuid4()
std.assert	assert, assert_eq, assert_ne, assert_throws
std.file	File read/write, list, glob, temp, ...
std.path	Path resolution and decomposition
std.env	Environment variables, args
std.time	Time, timers, calendars, unit conversion
std.async	spawn, await, sleep, defer, race
std.net	TCP / UDP / HTTP / WebSocket, DNS, URLs

Some shortcuts are regular callable functions on std, not module objects (see std.os).

Colon is never used to call module or member functions — use dot (std.string.upper(...), ops.add(...)). Colon is only for pipes acting on a value.

Concurrency

• Overview — fibers, yield points, mental model
• Spawn & Await — futures and overlapping work
• Primitives: Sleep · Defer · Race
• Patterns — fan-out, parallel HTTP, keep-alive
• Errors — await vs last_error()

Network

• TCP — tcp_client / tcp_server
• UDP — udp datagrams
• HTTP Client — http_client
• HTTP Server — http_server + routes
• WebSocket — websocket
• URL — parse_url
• DNS — dns_lookup
• HTTP Codes — http_codes constants
• Overview: std.net
