問題描述

有什么方法可以將 C 代碼轉換為 JavaScript 并從 JavaScript 轉換為 C?我發現 V8 juice 可以從 C++ 生成 JavaScript-side 類，但這只是一種方式(C++ 到 JavaScript).

Is there any way to convert C code to JavaScript and from JavaScript to C? I found V8 juice which can generate JavaScript-side classes from C++, but it's only one way (C++ to JavaScript).

我不是在尋找軟件.

推薦答案

非常非常棘手 --- Javascript 是一種高度動態的語言，幾乎所有東西都可以在運行時更改:變量名、函數名、類型等. 因此，它非常糟糕地映射到 C 上.這甚至沒有考慮 eval()，它可以讓您在字符串中構造任意 Javascript 塊并運行它們.

Very, very tricky --- Javascript is a heavily dynamic language where pretty much everything can be changed at run time: names of variables, functions, types, etc. As such it maps very badly onto C. And that's not even considering eval(), which will let you construct arbitrary chunks of Javascript in strings and run them.

任何 Javascript 翻譯器都必須能夠處理這些事情，這意味著它必須在運行時將 Javascript 翻譯成 C --- 這使它成為 JIT，您已經在使用它.

Any Javascript translator would have to be able to cope with such things, which means it would have to translate the Javascript into C at run-time --- which makes it a JIT, which you're already using.

您可能希望改為考慮為 Javascript 編寫 C 綁定.這些將允許您的 Javascript 代碼調用 C 代碼，反之亦然.這將允許人們用 C 編寫插件，將它們編譯成 .so 共享庫，您現在可以從 Javascript 代碼加載和運行這些共享庫.這意味著您不需要翻譯任何內容.

You may want to look at writing C bindings for Javascript instead. These will allow your Javascript code to call out to C code and vice versa. This would allow people to write plugins in C, compile them into .so shared libraries, which you can now load and run from your Javascript code. This means you don't need to translate anything.

Javascript 不是我的領域，所以我不能推薦任何特定的機制，恐怕 --- 但如果你已經找到的 V8Juice 不允許你這樣做，我會感到非常驚訝.

Javascript's not my area so I can't recommend any particular mechanism, I'm afraid --- but I'd be very surprised if V8Juice, which you've already found, didn't let you do this.
