Ruby：在一个项目中针对多个平台

我正在创建一个 [Iron]Ruby 项目，需要支持多种环境（更具体地说，WPF、Silverlight 和 WinForms - 但这并不那么重要）。以下是我陷入困境的实际具体示例：

我必须实现一个 Bitmap 类作为库的一部分，并且该类需要根据其运行的环境以不同的方式实现（例如，如果我在浏览器中将其作为 silverlight 应用程序运行，我将无法访问桌面上可用的方法）。问题是 - 我不控制 Bitmap 的实例化，也不控制库中任何其他类的实例化。为什么？因为它是另一个应用程序的端口；而且，虽然我确实有应用程序的代码，但我不想通过更改该代码来破坏兼容性。不过，我确实控制了应用程序的入口点，因此我可以require我需要的任何内容、执行设置、配置全局变量等。

编辑：< /strong> 如果你好奇，这是我正在从事的项目： http://github.com/cstrahan/open-rpg-maker

这是我的内容想知道：

我应该如何在启动时设置配置，以便 Bitmap 能够正常运行？
我应该如何在我的 git 存储库/源代码树中构建它？

以下是我的一些想法，但我相信您会有更好的想法：

我应该如何在启动时设置配置？
- 分发应用程序时，根据目标环境在顶部放置 require，如下所示：require silverlight/bitmap。在这种情况下，lib/bitmap.rb 将为空，而 lib/silverlight/bitmap.rb 将包含实现。 或者...
- 将所有实现填充到lib/bitmap.rb中，并根据类实例变量或常量有条件地执行：Bitmap.impl = "silverlight"。 或者...
- 为每个发行版维护一个单独的分支 - 尽管库几乎完全相同。
我应该如何在我的 git 存储库/源代码树中构建它？
- 每个发行版都有单独的分支。 或者...
- 单独的特定于实现的子文件夹（例如lib/silverlight/bitmap.rb）。

作为 Ruby 的新手，我对此类最佳实践不太熟悉（我来自 C#）。任何建议将不胜感激！

I am creating an [Iron]Ruby project that needs to support several environments (more specifically, WPF, Silverlight, and WinForms - but that's not as important). The following is an actual, concrete example of where I'm stuck:

I have to implement a Bitmap class as part of a library, and this class will need to be implemented differently depending on what environment it's running in (e.g. if I'm running this in the browser as a silverlight app, I won't have access to methods that would be available on the desktop). And here's the catch - I don't control the instantiation of Bitmap, nor any of the other classes within the library. Why? Because it's a port of another application; and, while I do have the code for the application, I don't want to break compatibility by changing that code. I do, however, control the entry point to the application, so I can require whatever I need, perform setup, configure global variables, etc.

Edit: If you're curious, this is the project I'm working on:

Here's what I want to know:

How should I set the configuration at startup, such that Bitmap will behave appropriately?
How should I structure this in my git repo / source tree?

Here are some of my thoughts, but I'm sure you'll have better ideas:

How should I set the configuration at startup?
- When distributing the app, place a require at the top depending on the targeted environment, like so: require silverlight/bitmap. In this case, lib/bitmap.rb would be empty, while lib/silverlight/bitmap.rb would contain the implementation. Or...
- Stuff all implementations in lib/bitmap.rb, and conditionally execute based on a class instance variable or constant: Bitmap.impl = "silverlight". Or...
- Maintain a separate branch for each distro - despite the library being almost exactly the same.
How should I structure this in my git repo / source tree?
- Separate branches per distribution. Or...
- Separate implementation-specific subfolders (e.g. lib/silverlight/bitmap.rb).
