关于给python对接spine runtimes问题

GuYeying

  您好，我作为一名狂热的程序开发者，发现spine在python上并没有相关的直接支持，其实早在去年就尝试让python也能使用高级的spine动画并在论坛讨论这个想法，最后我通过pybind11将spine runtimes的c++绑定并编译成python的动态链接库，并且成功使用pysdl+pyopengl完成复刻spine runtimes中spine-glfw案例的动画渲染。
   作为开发者我已经注意到代码版权和开源协议的问题。我看到官方说明需要有许可证才可以对源代码进行二次分发和使用。因为我不是美术和动画专业的所以我并没有购买spine editor许可证，所以我希望官方能否给个解决方案或者一个特殊的许可证方便我对他进行操作，这样我可以预编译为pypi的wheel方便各个平台的开发者直接安装使用，但他们使用也必须是遵守spine runtimes开源协议的。

根据Spine的许可协议，使用和分发Spine Runtimes需要拥有Spine许可证。虽然你可以在个人项目中使用Spine Runtimes进行开发，但要将其作为库分发（例如通过PyPI），则需要确保遵循Spine Runtimes的许可协议。这意味着你需要一个有效的Spine许可证来合法地分发包含Spine Runtimes的任何软件。对于你提到的特殊许可证请求，目前没有公开的特殊许可选项。建议你联系Esoteric Software以获取更多信息或可能的解决方案。

Here you can find the Spine Runtime License Agreement: https://en.esotericsoftware.com/spine-runtimes-license

If you are an SDK/library developer and don’t want to have a Spine license, the important part to analyze is this one:

Otherwise, it is permitted to integrate the Spine Runtimes into software or otherwise create derivative works of the Spine Runtimes (collectively, "Products"), provided that each user of the Products must obtain their own Spine Editor license and redistribution of the Products in any form must include this license and copyright notice.

This means that you can integrate the Spine Runtimes into your library under these two conditions:

Each user of the Products must obtain their own Spine Editor license → the users of your library must have a license.
Redistribution of the Products in any form must include this license and copyright notice → your library must include this license and copyright notice.

Point 2 is pretty simple: add the LICENSE file to your library.

For Point 1, just make sure it’s clear to your users that using your library requires a Spine license.

In any case, take into account that we are in the process of releasing 4.3 and it might requires a lot of effort to port to 4.3 your bindings.

I have created two pairs of README and LICENSE files: README, README-SPINE, LICENSE, and LICENSE-SPINE.
The files with the "-SPINE" suffix (i.e., README-SPINE and LICENSE-SPINE) are copied from the Spine C++ runtimes.
I would appreciate it if you could check these files to see if they comply with your rules.
The contents of my README and LICENSE files are as follows:

- README:  
# Spine Runtimes C++ Bindings for Python(Alpha)
## Important License Notice
1. This project consists of two parts of code:
   - **Original Code**: The pybind11 binding logic and Python-layer rendering implementation developed by [Your Name], which is licensed under the MIT License (see the LICENSE file for details).
   - **Third-Party Code**: The C++ code based on spine-runtimes, whose copyright and license belong to the original author (Esoteric Software). Users must strictly comply with the [official spine-runtimes license](https://github.com/EsotericSoftware/spine-runtimes/blob/4.2/LICENSE or see the LICENSE-SPINE file for details).
2. When using this project, users must comply with both of the above licenses. Any consequences arising from non-compliance with any license shall be borne by the user.
3. It is emphasized again that the right to use code related to spine-runtimes is governed by its original license. The MIT License of this project applies solely to the original code written by the developer and does not alter the copyright or licensing terms of third-party code.
## Project Description
- **Version**: Alpha v0.01  
- **Scope**: This version is functionally aligned with the `spine-glfw` example in spine-runtimes. It only guarantees the stability of core features covered by this example, and does not ensure compatibility with other modules (untested issues may exist).  
- **Core Feature**: OpenGL rendering logic is fully implemented in the Python layer. Developers do not need to worry about graphics library selection, rendering process adaptation, or version dependencies. Rendering logic can be flexibly modified directly in Python.  
## Contribution
Issues and Stars are welcome!
