Animus

Animus is a template CMake project that utilizes Djinni to generate Swift, Objective-C and Java bindings for modern C++. This is particularly useful for developing cross-platform mobile applications with common application logic.

The goal is this project is to provide:

• A core library template that can be used in the most native way for the IDE at hand
  • In Xcode, we build a framework with a modulemap included; This allows us to use the libraries created with a simple `import' statement, rather than requiring a bridging header
  • In Android Studio, we ensure that the CMake file can be consumed by Android Studio's gradle file out-of-the-box
• Support for out of source builds by default
• A modern CMake and C++ cross-platform implementation

Quick start

git clone https://github.com/sgerbino/animus.git
git submodule update --init --recursive
mkdir build
cd build
cmake .. -G Xcode

Usage

Define your core application interface in $PROJECT_SOURCE_DIR/rc/djinni/interface_definition.djinni and implement your interface in C++ in $PROJECT_SOURCE_DIR/src/cpp.

Android

To use an animus based project in Android Studio, open your Android project build.gradle and add the following snippets to the necessary sections.

android {
    defaultConfig {
        externalNativeBuild {
            cmake {
                cppFlags "-std=c++14 -fexceptions"
                arguments "-DANDROID_STL=c++_static"
            }
        }
    }
    externalNativeBuild {
        cmake {
            path "deps/animus/CMakeLists.txt"
        }
    }
}

Examples

Apple example

After building the project on macOS, a framework will be generated. Including this in a project will allow you to use your core API from Objective-C and/or Swift.

import Animus
...
var api = Api.createApi(AppleEventLoop(), httpClient: AppleHttp(), threadLauncher: AppleThreadLauncher())
