CPM — Cpyte Package Manager

A compiler-pipeline dependency resolver and installer for the Cpyte programming language.

import @std.json

Resolve → Lower → Optimize → Execute

Install

pip install cpyte-cpm

Note: CPM uses the Cpyte package registry at https://cypackage.5gnew.io.vn/ as the default package source for Cpyte packages. The default registry is configured in pyproject.toml.

Quick Start

cpm init                        # create cpytoml
cpm add @std/json@^2.0          # add a dependency
cpm install                     # install all from manifest

Commands

Command	Description
cpm init	Initialize a new project (cpytoml)
cpm add <pkg>	Add packages to manifest + install
cpm remove <pkg>	Remove packages + uninstall
cpm install	Install all dependencies from manifest
cpm install <pkg>	Install specific packages
cpm update	Re-resolve and update all packages
cpm update <pkg>	Re-resolve specific packages
cpm build	Build the project
cpm run <script>	Run a named script

Global Flags

-v, --verbose        Verbose output
-q, --quiet          Suppress output
-y, --yes            Auto-confirm prompts
--offline            Offline mode (skip network)
--no-cache           Disable cache
--config <path>      Custom config / repo URL
--target <platform>  Target platform (e.g. linux/x86_64)
--llvm-version <V>   LLVM version for prebuilt packages

Manifest (cpytoml)

[cpm]
name = "my-app"
version = "1.0"
prebuilt = false
llvm_version = "18.1.0"

[cpm.target]
os = "linux"
arch = "x86_64"
features = ["gui", "ssl"]

[cpm.dependencies]
"@std/json" = "^2.0"
"@std/http" = "1.0"
"package_a" = "latest"

Claims System

Packages declare platform support; CPM filters based on your target.

Package metadata (registry):

{
  "name": "win32-api",
  "claims": { "os": ["windows"], "arch": ["x86_64"] }
}

Resolution:

Target	win32-api (windows)	posix-api (linux)	@std/json (any)
linux/x86_64	skip	install	install
windows/x86_64	install	skip	install

Auto-detects from current platform when no target is specified.

Prebuilt Mode

When the registry serves precompiled LLVM IR:

[cpm]
prebuilt = true
llvm_version = "18.1.0"

CPM fetches .ll artifacts from metadata/prebuilt/... and skips source packages with incompatible LLVM versions (major version must match).

Lockfile (cpm.lock)

Auto-generated. Pins exact versions for reproducible builds.

[[package]]
name = "@std/json"
version = "2.0.3"
resolved = "https://repo.example.com/group/std/json/2.0.3.tar.gz"
checksum = "sha256:abc123..."
dependencies = ["@std/encoding@1.2.0"]
llvm_version = "18.1.0"
cpyte_version = "0.5.0"
