djinni_build.py 🦎

Utility to package and distribute Djinni libraries easily.

Requirements

• A project structure close to jothepro/djinni-library-template
• Should be used together with jothepro/djinni-cmake.
• Python >= 3.10

What it does

This utility automates the building & packaging for Djinni libraries.

It supports these platforms:

• Android (AAR)
• iOS (xcframework, Swiftpackage)
• macOS (xcframework, Swiftpackage)
• Windows (NuGet .NET package)
• Linux (Conan)

DjinniBuild provides a CLI that allows the user to configure what the output should be.

The user is able to configure:

• What target platform to build for (Android, iOS, macOS, Windows, Linux)
• Which architectures to build for (x86, x86_64, armv7, armv8)
• How to package the resulting binaries (AAR, NuGet, XCFramework, Swift Package, Conan)

For every target language, the following steps are executed:

• Configure Project & Install Dependencies: Runs conan install for each target architecture & target platform to configure the CMake project and install all dependencies defined in the Conanfile.
• Build: Runs conan build for each requested target architecture & platform
• Package: Executes the platform specific packaging tasks.

How to use

Install djinni_build from PYPi:

pip install djinni_build

Then import DjinniBuild and configure the project structure and then execute the main() function:

#!/usr/bin/env python3

from djinni_build import DjinniBuild

djinniBuild = DjinniBuild(
  darwin_target='MyDjinniLibrary',
  windows_target='MyDjinniLibrary',
  android_target='MyDjinniLibrary',
  android_module_name='MyDjinniLibrary',
  nupkg_name='MyDjinniLibrary',
  conan_user='jothepro',
  conan_channel='release'
)
djinniBuild.main()

In its current state not everything in the script is configurable and some things will only work if the correct directory structures and files are present. It is recommended to strictly stick with the project structure of jothepro/djinni-library-template to avoid compatibility issues!

CLI Interface

This example output from the CLI shows what the configuration options for the user are:

usage: build.py [-h] [--configuration {release,debug}] [--android [{x86_64,x86,armv8,armv7} ...]] [--macos [{armv8,x86_64} ...]]
                [--iphonesimulator [{armv8,x86_64} ...]] [--iphoneos [{armv8,armv7} ...]] [--windows [{x86_64,x86,armv8,armv7} ...]]
                [--linux [{x86_64,x86,armv8,armv7} ...]] [--build-directory BUILD_DIRECTORY] [--build-profile CONAN_BUILD_PROFILE]
                [--package [{xcframework,swiftpackage,conan,aar,nuget} ...]]
