ocebuild 0.0.0.dev0

Portable OpenCore EFI dependency & build manager.

OCE Build

A minimal framework for fast, secure, and reliable build and dependency management for OpenCore EFIs.

OCE-Build is designed to help enable projects to be highly composable and easily maintainable, prioritizing a small git-friendly footprint. It is designed to be flexible and extensible for existing projects, while also providing a simple configuration and interface for new projects to get started quickly.

Feature Overview

Note: This project is still in early development and is not yet ready for general use. The following is a list of features that are planned for the initial release.

• Declarative Configuration
  • Minimal project configuration.
  • Flexible support for any project structure.
  • Shared/Template config.plist configurations.
  • Automated config.plist schema conflict resolution.
• Version Management
  • Versioning for OpenCore binaries and resources (Kexts, SSDTs, etc).
  • Automatic version resolution for dependencies.
  • Lockfile creation for intelligent registry management.
• Build Support
  • Incremental builds and cache management from lockfile.
  • Advanced ACPI language support, including compiler and patchfile options.
  • Dependency sorting for proper prelink injection (i.e. SSDTs, Kexts).
  • CI support for managing and building Kexts with XCode.

Installation

This project is distributed as both a standalone CLI and a Python library on PyPI. The CLI is intended to be used for simple projects or for CI/CD, while the library is intended to be used for supporting Python library development or complex build pipelines. The library also comes bundled with the CLI and it's source code is available under the ocebuild.cli module.

The recommended way to install the CLI is from GitHub releases. This will provide you with a standalone executable that can be used without installing Python or any other dependencies. The CLI is available for Windows, macOS, and Linux.

To install the CLI / library from PyPI, you will need to have Python 3.8 or later installed. You can install Python from python.org or from your package manager. For more information on installing Python, refer to the Python documentation.

To install the library directly from PyPI using pip, simply run the following command in your terminal:

pip install ocebuild

Or when using the poetry package manager, run:

poetry add ocebuild

Depending on your system, you may need to use pip3 instead of pip when installing the library. You may also need to use sudo or pip install --user to install the library globally or locally, respectively.

After installing the library, the CLI will also be available in your PATH, which you can invoke by simply running ocebuild in your terminal (or poetry run ocebuild).

Getting Started

To get started, you will need to create a build.yml file in the root of your project. This file will contain all of the information needed to build your EFI. You can follow along with the below example or reference one of the example projects included in this repository.

The following is a minimal example of a build.yml file located under a src/ directory:

# src/build.yml
---
build: DEBUG
version: latest
---
ACPI:
Drivers:
  - AudioDxe
  - HfsPlus
  - OpenRuntime
  - ResetNvramEntry
Kexts:
  Lilu: latest
  VirtualSMC: latest
Resources:
Tools:
  - OpenShell

Once you have created your build.yml file, you can run the build command to build your EFI:

ocebuild build --cwd src/build.yml

This will create a new dist/ directory in your project containing your EFI. You can also specify a custom output directory by using the -o / --output option. To view all available commands and options, run ocebuild --help or run ocebuild <command> --help for more information on a specific command.

Refer to docs/configuration.md for more information on how to setup your build configuration.

Note that this does not output a config.plist file. To generate a config.plist file, you will need to create a config.yml file in the same directory as your build.yml file. The config.yml file contains only the changes you wish to make to the default Sample.plist file (located under dist/Docs/Sample.plist). Refer to docs/configuration.md for more information.

Guidelines and Philosophy

The general philosophy for this project is to keep things as simple as possible. This means that the project should be easy to understand, easy to maintain, and easy to contribute to.

A summary of the contributing guidelines for this project are as follows:

• Create an issue for any major changes and enhancements that you wish to make.
  • If you find a security vulnerability, do NOT open an issue. Please refer to our Security Policy for reporting security vulnerabilities.
  • For questions or discussions related to this project, please open a new GitHub discussion instead of opening an issue.
• Create a pull request for your changes and coordinate with the project maintainers to get it merged to main.
  • Include unit tests when you contribute new features or fix a bug. This:
    • Proves that your code works correctly and prevents regressions from going unnoticed.
    • Guards against breaking changes to the public API and ensures that the project can remain backwards compatible.
    • Lowers the maintenance cost of the project by making it easier to troubleshoot and debug issues.
  • Keep compatibility and cohesiveness mind when contributing a change that will impact the public API. This helps limit the scope of changes to only what is required to implement the new feature or fix the bug.
