Example for Scapix Language Bridge

On the fly code generation to bridge C++ to Java, Objective-C, Swift, Python, JavaScript (WebAssembly) and C#.

1. Change your C++ code and build your project (bindings generated as part of the build).
2. Call newly changed C++ code from Java, Objective-C, Swift, Python, JavaScript or C#.

Install

$ git clone https://github.com/scapix-com/example1

Build

build.sh script (or build.cmd on Windows) runs CMake configure and build steps using selected CMake preset.

• Run build script without parameters to see list of available CMake presets.
• Run build script specifying one the the presets to create and build library project (chatlib).
• Open corresponding platform specific application project in ui folder (chat).

macOS

• Run: ./build.sh xcode-objc
• Open in Xcode: ui/macos/chat.xcworkspace

iOS

• Run: ./build.sh xcode-objc-ios
• Open in Xcode: ui/ios/chat.xcworkspace

tvOS

• Run: ./build.sh xcode-objc-tvos

watchOS

• Run: ./build.sh xcode-objc-watchos

visionOS

• Run: ./build.sh xcode-objc-visionos

Android (on Windows, macOS or Linux)

• Open in Android Studio: ui/android
• Requires: Ninja, see Install CMake and Ninja

Python (on Windows, macOS or Linux)

$ ./build.sh python
$ cd ui/python
$ ./run.py

You can also specify CMake generator explicitly and then open generated project in corresponding IDE:

$ build vs2019-python
$ build vs2022-python
$ ./build.sh xcode-python

Java (on Windows, macOS or Linux)

$ ./build.sh java

You can also specify CMake generator explicitly and then open generated project in corresponding IDE:

$ build vs2019-java
$ build vs2022-java
$ ./build.sh xcode-java

JavaScript (Emscripten)

Install Emscripten SDK

$ ./build.sh js
$ cd ui/js
$ ./serve.sh

On Windows use ninja-js preset, as Emscripten SDK doesn't support Visual Studio CMake generators:

$ build ninja-js
$ cd ui/js
$ serve.sh

C#

$ build vs2022-cs

Open Visual Studio solution: build\vs2022-cs\ui\cs\chat.sln
