Well, if you have to build a house, a hammer will work just fine. But building a house using a pneumatic framing nailer is much easier.

C++ is a fine language and you can be productive in areas that are dominated by scripting languages, but all things equal, you will be more productive using perl/python for text parsing.

blocks|key|1117195|text|C%2B%2B不是专门为处理长文本字符串而设计的。(只要看看旧的C-Strings...对于任何严重的事情来说，它们都是一个噩梦。)相比之下，Perl就是为这种用途而生的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1117196|您也许可以用C%2B%2B把一些东西拼凑在一起，但是Perl解决方案可能更健壮、更易于维护。|1117197|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|$]]

C++ was not specially designed to handle long strings of text. (Just look at the old C-Strings... they were a nightmare for anything serious.) By contrast, Perl was made for this sort of use.

You can probably cruft together something in C++, but a Perl solution will probably be more robust and maintainable.

blocks|key|4901954|text|为什么不行？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4901955|如果你的代码因为缺少库/功能而变得粗糙，那么C%2B%2B可能不是最好的。如果需要经常更改，那么C%2B%2B可能不是最好的。如果其他懂Perl/Python的人会维护它，那么C%2B%2B可能不是最好的。等。|4901956|您真的需要GUI吗？你需要速度吗？没有任何改变使C%2B%2B成为脚本语言，但这并不意味着您不应该使用它。|4901957|如果它通过了像这样的常识测试，那为什么不呢？|4901958|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

Why not?

If you're code is going to be hacky because of lack of libraries/features, then C++ might not be best.
If it needs to change often, then C++ might not be best.
If others who know Perl/Python will maintain it, then C++ might not be best.
etc.

Do you really need a GUI? Do you need the speed? Nothing has changed to make C++ a scripting language, but that doesn't mean you shouldn't use it.

If it passes common sense tests like this, than why not?

blocks|key|1154338|text|对于您的示例，您似乎会更有效率，并且能够更容易地使用C%2B%2B解决问题，因为这是您所知道的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1154339|但总的来说，我预计会有更多的人使用python/perl来完成这类任务。|1154340|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|$]]

For your example it seems that you will be more productive and able to solve your problem more easily using C++ as that is what you know.

But generally I would expect that more people would use python/perl for this kind of task.

blocks|key|3433622|text|其他人通常期望解决方案是什么又有什么关系呢？如果可以在C%2B%2B中更好更快地完成工作，那么在C%2B%2B中完成它，故事结束。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3433623|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|$]]

What does it matter what other people might usually expect the solution to be? If you can get the work done better and faster in C++, do it in C++, end of story.

blocks|key|1117332|text|C/C%2B%2B与python/perl的生产率问题对我来说似乎无关紧要。如果您想使用Qt、Boost和任何其他现成的工具集编写解析器，请执行此操作。实际上，您并没有指定解析速度是否是一个问题，但即使是这样，它对您的情况也有影响吗？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1117333|即使你认为在X语言中可能会更容易，如果你想尝试和学习一些关于该语言的新东西，也可以用Y语言来写。这听起来像是一项非常简单的任务，所以只要按照你想要的方式来写就行了。|1117334|您还需要考虑将来的使用情况。如果该程序需要以某种方式进行增强和扩展，则可能需要指定特定的语言选择。|1117335|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

The issue of productivity of C/C++ vs. python/perl seems irrelevant to me. If you want to write your parser using Qt, Boost, and any other off the shelf tool sets, do it. You didn't actually specify if the speed of parsing is an issue, but even if it was, would it even matter for your case.

Even if you think that it might be easier in language X, write it in language Y if you want to try and learn something new about that language. It sounds like a pretty easy task so just write it how you want to write it. 

You also need to think about future use. If this program will need to be enhanced and extended in some way, that might dictate a specific language choice.

blocks|key|4902105|text|如果你在C%2B%2B中效率更高，那么一定要使用C%2B%2B。学习其他语言仍然是一个好主意，但有时你需要用你所知道的去做事情。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4902106|顺便说一句，您可能已经知道这一点，但是Boost.Tokenizer库具有通过escaped+list+separator内置的CSV解析功能。|offset|length|4902107|entityMap|0|LINK|mutability|MUTABLE|url|http://www.boost.org/doc/libs/1_39_0/libs/tokenizer/index.html|1|http://www.boost.org/doc/libs/1_39_0/libs/tokenizer/escaped_list_separator.htm^0|0|J|F|0|13|M|1|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@$D|R|E|S|1|T]|$D|U|E|V|1|W]]|A|$]]|$1|F|3|-4|5|6|7|X|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]|N|$5|I|J|K|A|$L|O]]]]

If you're more productive in C++ then by all means use C++. It's still a good idea to learn other languages, but sometimes you need to go with what you know to get things done.

BTW, you probably already know this, but the <a href="http://www.boost.org/doc/libs/1_39_0/libs/tokenizer/index.html" rel="nofollow noreferrer">Boost.Tokenizer</a> library has CSV parsing capabilities built-in through the <a href="http://www.boost.org/doc/libs/1_39_0/libs/tokenizer/escaped_list_separator.htm" rel="nofollow noreferrer">escaped list separator</a>.

blocks|key|4902131|text|从你的描述来看，除了锤子，你好像还有其他工具。你拥有的工具越多，你做事情的效率就越高。使用你可以使用的任何工具来完成工作，偶尔购买(学习)更多的工具。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4902132|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|$]]

From your description, it sounds like you have other tools besides a hammer. The more tools you have, the more efficiently you can get things done. Use whatever tools you have at your disposal to get the job done, and occasionally buy (learn) more tools.

blocks|key|3433753|text|我喜欢C%2B%2B。我讨厌编译、运行、测试、关闭循环--特别是当我需要测试数据的时候。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3433754|我的解决方案是:我做了一个由Lua驱动的小型编程环境，我将其嵌入到我的C%2B%2B应用程序中，并在运行时打开它，以交互方式进行操作。为什么要停留在一个或另一个编程环境上呢？使用两全其美的。|3433755|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|$]]

I like C++. I hate the compile, run, test, close cycle - specifically when I need to test data. My solution: I made a small programming environment [powered by Lua] which I embed in my C++ applications and I open it at run-time and do stuff interactively. Why to stick at one programming environment or another? Use the best of both worlds.

I need to download some csv files over http from the internet, parse it and convert it to a more useful fomat. Eventually a C++ program will consume the data. A few years ago, I would be pulling out my Perl books and start writing Perl scripts to do the downloading and parsing. But now with Boost and Qt I can do the download, parsing, and throw in a GUI front end in C++ with very little effort. Last time I wrote Perl/Python was about 6 months ago. It will probably take me longer to do it in Perl/Python and my Perl/Python code will be crap. If the only tool I have is a hammer, everything looks like a nail? Or time has changed and C++ can be productive in area traditionally dominated by script languages such as Perl or Python?
