ELP

Site

ELP — Ely Language Package Manager. The official package manager for the Ely programming language, included with ElySpruce since version 26.5.

Overview

ELP manages modules and dependencies for Ely projects. It handles installation, removal, updating, and publishing of packages from both local directories and remote GitHub repositories.

Commands

Command	Description
elp init [name]	Create a new elymodule.json + src/ scaffold
elp install <pkg>[@ver]	Install a package from stdmodules or GitHub
elp install-local <path>	Install a package from a local directory
elp remove <pkg>	Remove an installed package
elp update	Update all dependencies
elp list	List installed packages
elp list-available	List available standard modules (stdmodules/)
elp pack [--output <file>]	Pack project into .elypkg archive
elp publish	Publish to local registry
elp info <pkg>	Show package metadata
elp build [path]	Build project (path = directory or manager.json)
elp run [path]	Build & run project

How It Works

ELP integrates with the Ely build system (ebt). When you run elp install, the package manager:

• Resolves the package from stdmodules/ (built-in standard library) or a GitHub repository
• Downloads and builds the package as a static library (.lib / .a)
• Generates link.ely — a wrapper that exposes the module's public API to your Ely code
• Copies compiled artifacts into ex_prj/modules/ for direct use in your project
• Updates manager.json with the module's path automatically

Manager.json Integration

ELP reads and writes the modules field in your project's manager.json:

{
    "name": "my_project",
    "enter": "main.ely",
    "modules": {
        "file": "modules/file/elymodule.json",
        "json": "modules/json/elymodule.json"
    }
}

Each module path points to an elymodule.json that describes the module's API, link file, and included assets.

Example

// Install the file module
elp install file

// Use it in your Ely code
using "modules/file/link.ely";

File f = File("test.txt");
f.setContent("Hello from ELP!");
println(f.getContent());

Notes

• ELP is a core component of ElySpruce and is required for compilation since version 26.5
• Standard modules are located in stdmodules/ and are always available offline
• Remote packages are fetched via GitHub and cached locally
• Module compilation produces static libraries for maximum performance
• The package manager automatically resolves transitive dependencies

Quick Start

• Ensure ElySpruce 26.5+ is installed
• Navigate to your Ely project directory (with a manager.json)
• Run elp install file to add the file module
• Add using "modules/file/link.ely"; to your .ely source
• Build and run with elp run
