与不区分大小写的语言相比，区分大小写的语言有什么优势？ [英] What's the advantage of case sensitive languages over case insensitive ones?

问题描述

我一直在Delphi中做过许多项目，这些项目使用不区分大小写的语言Pascal，并且我想知道区分大小写的语言的优点是什么。

Jason 争论不区分大小写会带来很多歧义。我不同意如果您意识到该语言不区分大小写，则知道 WHILE 与 while 的含义相同，即使您从未写前者。变量和函数相同；骆驼的外壳很好，但是首字母还是大写吗？那么以下划线开头的函数呢？在不区分大小写的语言中，没问题： _fooBar 的效果与 _FooBar 一样好。那么Jason指的是什么歧义？是的，您可以用不同的方式编写变量，但是含义是明确的！ FooBar == foobar ！

I have been doing a number of projects in Delp which uses the case insensitive language Pascal, and I was wondering what the advantage of case sensitive languages is.
Jason argues that "Case insensitivity introduces much ambiguity". I don't agree. If you realize that the language is case insensitive you know that WHILE means the same thing as while, even if you never write the former. Same for variables and functions; camel casing is nice, but was the first letter also a capital or not? And what about functions whose name starts with an underscore? In case insensitive languages no problem: _fooBar will do just as nicely as _FooBar. So where's the ambiguity Jason refers to? Yes, you can write a variable in different ways, but the meaning is unambiguous! FooBar == foobar!

在同一线程中德尔南说表示资本化是我不得不帮助我叔叔杰克下马..和我不得不帮助我叔叔杰克下马。 。非常聪明 ：-）。但这不是对大小写敏感的反对：您是否会因为一个大写错误而使代码陷入困境？同样，在不区分大小写的语言中，如果 Jack 是人，那么 jack 也是人。

In the same thread Delnan says that Capitalization is the difference between "I had to help my uncle Jack off a horse.." and "I had to help my uncle jack off a horse..". Very clever :-). But rather a point against than pro case sensitivity: would you accept that your code goes haywire because of a single capitalization error? Again, in a case insensitive language, if Jack is a person, so is jack.

问题：是否有人在区分大小写的语言中使用此功能，您可以仅通过不同的大小写来定义两个不同的变量或函数？因为那是我所能看到的唯一优势。当然，您会说，我用驼峰式大小写变量名，并用大写形式写常量。但是IMO它们是不兼容的； userName 作为变量是有意义的，但 USERNAME 作为常量则没有意义。

Question: is there anyone who uses this feature in case sensitive languages that you can define two different variables or functions just by different capitalization? Because that's the only advantage I can see in it. Sure, you'll say, I write the variable name with camel casing and the constant all uppercase. But IMO they're incompatible; userName as a variable makes sense, but USERNAME as a constant doesn't.

（我意识到许多程序员都使用区分大小写的语言，所以我准备接受不受欢迎的接待：-））

(I realize that many programmers use case sensitive languages, so I'm prepared for a unwelcome reception :-))

这个问题的触发源是Lynda.com的 Flash CS3 Professional中的ActionScript 3.0培训视频，其中Todd Perkins花费了一半的时间来强调大写：-）

The trigger for this question was Lynda.com's "ActionScript 3.0 in Flash CS3 Professional" training video, in which Todd Perkins spends half of his time emphasizing the capitalizations :-)

推荐答案

是的，我绝对在C＃中一直使用它：

Yes, I absolutely use this all the time in C#:

private readonly string name;
public string Name { get { return name; } }

我倾向于使用区分大小写的语言，并且还没有真正看到它们-除了其他以外，它们力大小写一致。

I've tended to use case-sensitive languages, and haven't really seen downsides of them - aside from anything else, they force consistency of casing.

不过，我认为这确实是个人喜好。

It's really a personal preference thing though, I think.
