blocks|key|250559|text|几乎你选择的任何语言都会有一些功能不会以自然的方式映射到另一种语言。我能想到的最接近的东西可能是JavaScript的一个有用的子集。当然，如果您是语言作者，您可以根据需要对其进行限制，只提供对任何语言通用的结构(循环、条件等)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|250560|出于可变性的目的，XML表示将是最好的，但是您不会想要在其中编码。|250561|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Just about any language that you choose is going to have some feature that doesn't map to another in a natural way. The closest thing I can think of is probably a useful subset of JavaScript. Of course, if you are the language author you can limit it as much as you want, providing only constructs that are common to just about any language (loops, conditionals, etc.)

For purposes of mutability, an XML representation would be best, but you wouldn't want to code in it.

blocks|key|250587|text|经典的Pascal非常简单。Oberon是另一个类似的选择。或者，您可以发明自己的派生语言，类似于计算机科学教科书中的伪代码。实现一个从其中一种语言到任何一种现代命令式语言的翻译器是很容易的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|250588|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

A classic Pascal is very simple. Oberon is another similar option. Or you could invent your own derivative language similar to the pseudocode from the computer science textbooks. It's trivial to implement a translator from one of that languages into any decent modern imperative language.

blocks|key|2318518|text|如果您发现没有通用语言，可以尝试一种实用的模型驱动开发方法，使用基于模板的代码生成器。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2318519|在模板上，您保留了算法的基本概念。然后，您可以在必要时使用一种或多种特定语言(C%2B%2B、Java、JS、Python)添加此算法的代码。无论您选择哪种语言或方法，您都必须这样做。配置开关将为您应用的任何模板选择正确的语言。|2318520|AtomWeaver是一个代码生成器，它使用模板并使用ABSE作为建模方法。|offset|length|2318521|entityMap|0|LINK|mutability|MUTABLE|url|http://www.atomweaver.com/^0|0|0|0|A|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@$F|S|G|T|1|U]]|A|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]]]

If you find that there is no universal language, you can try a pragmatic model-driven development approach, using a template-based code generator.

On the template you keep the underlying concepts of an algorithm. Then, you would add code for this algorithm in one or more specific languages (C++,Java,JS,Python) when necessary. You would have to do it anyway, whatever the language or approach you choose. A configuration switch would pick the correct language for any template you apply.

looks interesting

I realize that it is impossible to have one language that is best for everything.

But there is a class of simple programs, whose source code looks virtually identical in any language. 

I am thinking not just "hello world", but also arithmetics, maybe string manipulation, basic stuff that you would typically see in utility classes.

I would like to keep my utilities in this meta-language and have it automatically translated to a bunch of popular languages. I do this by hand right now.

Again, I do not ask for translation of every single possible program. I am thinking a very limited, simple language, but superportable.

Do you know of anything like that? Is there a reason why it should not exist?

我意识到，不可能有一种语言是万能的。但是有一类简单的程序，它们的源代码在任何语言中看起来都是一样的。我想的不仅仅是"hello world"，还有算术，也许是字符串操作，你通常会在实用程序类中看到的基本东西。我希望将我的实用程序保留在这种元语言中，并将其自动翻译成一系列流行的语言。我现在用手来做这件事。再说一次，我不要...
