Official Packages

The kelvralang organization maintains a growing set of packages separately from the runtime. They use canonical github.com/kelvralang/... imports and are versioned independently, so check each repository’s Releases page when choosing a version.

Portable source packages

These packages are implemented in Kelvra and do not require a native compiler when installed.

encoding

Hex, Base64, URL encoding, and checksum helpers. Repository

json

JSON parsing, typed value access, and deterministic serialization. Repository

log

Configurable levels, filtering, and named console loggers. Repository

math

Portable numeric constants, bounds helpers, powers, and rounding. Repository

path

Cross-platform lexical path joining, normalization, and inspection. Repository

test

Assertions, equality checks, null checks, and approximate comparisons. Repository

Native packages

Native packages bridge Kelvra to platform services and C/C++ libraries. A Git dependency builds them from source; configured registries may provide prebuilt artifacts for a supported target.

Filesystem reads, writes, directories, copies, renames, and metadata. Repository

http

Callback-based HTTP and WebSocket servers, including binary payloads and connection-local Kelvra values. Repository

random

Seeded random generators, secure seeds, integers, booleans, and floats. Repository

time

Monotonic and Unix clocks plus millisecond and second sleeps. Repository

window

SDL2-backed windows, events, keyboard and mouse input, drawing, and text. Repository · Package guide

Hybrid package

ecs

A Kelvra source facade over a native-performance C++ entity-component system, with schemas, worlds, entities, components, and queries. Repository

Install and import

Choose a tag from the package repository, add it to your project, and import the canonical module path. For example:

kelvra add github.com/kelvralang/json@v0.2.0

const json = @import("github.com/kelvralang/json")
var value json.Json = json.parse("{\"language\":\"Kelvra\"}")
print(json.stringify(value))

kelvra add updates kelvra.toml, resolves the package, installs it, and updates kelvra.lock. Commit the lockfile for applications.
