解释自定义语言 [英] Interpreting custom language
问题描述
我需要开发一个将读取和理解文本文件的应用程序，在该文件中，我将找到描述操作列表(即烹饪食谱)的自定义语言.该语言尚未定义，但可能采用以下形状之一:
I need to develop an application that will read and understand text file in which I'll find a custom language that describe a list of operations (ie cooking recipe). This language has not been defined yet, but it will probably take one of the following shape :
- 类似于C ++的代码
(此代码是随机生成的，仅供参考):
(This code is randomly generated, just for example purpose) :
begin
repeat(10)
{
bar(toto, 10, 1999, xxx);
}
result = foo(xxxx, 10);
if(foo == ok)
{
...
}
else
{
...
}
end
- XML代码
- XML code
(此代码是随机生成的，仅供参考):
(This code is randomly generated, just for example purpose) :
<recipe>
<action name="foo" argument"bar, toto, xxx" repeat=10/>
<action name="bar" argument"xxxxx;10" condition="foo == ok">
<true>...</true>
<false>...</false>
</action>
</recipe>
无论选择哪种语言，都必须处理简单的条件，循环.
No matter which language will be chosen, there will have to handle simple conditions, loops.
我从没做过这样的事情，但是乍一看，我发现将这些操作描述为XML会更简单但功能却不那么强大.
I never did such a thing but at first sight, it occurs to me that describing those operations into XML would be simplier yet less powerful.
浏览StackOverFlow之后，我在一个名为"ANTLR"的工具上发现了一些聊天...我开始阅读权威ANTLR参考"，但是由于我从未做过这种事情，所以我很难知道它是否是确实是我需要的那种工具...
After browsing StackOverFlow, I've found some chats on a tool called "ANTLR"... I started reading "The Definitive ANTLR Reference" but since I never done that kind of stuff, I find it hard to know if it's really the kind of tool I need...
换句话说，我需要什么来读取文本文件，正确解释文本文件并执行我的C#代码中的操作.这些操作将通过以下简单条件在彼此之间进行交互:
In other words, what do I need to read a text file, interpret it properly and perform actions in my C# code. Those operations will interact between themselves by simple conditions like :
- 如果operation1失败，则执行operation2，否则执行operation3.
- 重复10次操作4次.
描述这些文本文件(XML，我自己的)的最佳语言是什么?这种发展过程中的关键点是什么?
What would be the best language to do describe those text file (XML, my own) ? What are the key points during such developments ?
我希望我很清楚:)
非常感谢您的帮助和建议！
Thanks a lot for your help and advices !
推荐答案
XML非常适合以冗长的方式存储关系数据.但是，我认为这是编写程序之类的逻辑的可怕选择.
XML is great for storing relational data in a verbose way. I think it is a terrible candidate for writing logic such as a program, however.
您是否考虑过使用可以嵌入的现有语法/脚本语言，而不是编写自己的语法/脚本语言?例如:
Have you considered using an existing grammar/scripting language that you can embed, rather than writing your own? E.g:
