最近Stack Overflow上有一群讨厌perl的人,所以我想我应该把我的“关于你最喜欢的语言你讨厌的五件事”的问题带到Stack Overflow上。拿你最喜欢的语言来说,告诉我你讨厌它的五件事。这些可能只是让你烦恼的事情,承认的设计缺陷,公认的性能问题,或任何其他类别。你只需要讨厌它,它必须是你最喜欢的语言。

不要拿它和其他语言比较,也不要谈论你已经讨厌的语言。不要用你最喜欢的语言谈论你喜欢的事情。我只是想听到你讨厌但能容忍的东西,这样你就可以使用所有其他的东西,我想听到你希望别人使用的语言。

每当有人试图把他们最喜欢的语言强加给我时,我就会问这个问题,有时是面试问题。如果有人找不出他最喜欢的工具的5个缺点,那他对它还不够了解,不能提倡它,也不能利用它赚大钱。他还没有在足够多的不同情况下使用它来充分探索它。他把它作为一种文化或宗教来倡导,这意味着如果我不选择他最喜欢的技术,我就错了。

我不在乎你用什么语言。不想使用特定的语言?那就不要。你通过尽职调查做出了明智的选择,但仍然没有使用它?好吧。有时正确的答案是“你有一个强大的编程团队,有良好的实践和丰富的Bar经验。改成Foo是愚蠢的。”


This is a good question for code reviews too. People who really know a codebase will have all sorts of suggestions for it, and those who don't know it so well have non-specific complaints. I ask things like "If you could start over on this project, what would you do differently?" In this fantasy land, users and programmers get to complain about anything and everything they don't like. "I want a better interface", "I want to separate the model from the view", "I'd use this module instead of this other one", "I'd rename this set of methods", or whatever they really don't like about the current situation. That's how I get a handle on how much a particular developer knows about the codebase. It's also a clue about how much of the programmer's ego is tied up in what he's telling me.

憎恨并不是衡量人们了解多少的唯一尺度,但我发现它是一个相当不错的尺度。他们讨厌的事情也让我知道他们对这个话题的思考有多好。


当前回答

C(好吧,这不是我最喜欢的,但当时还没人做过。)

套接字库语法。 没有函数重载。 c风格的字符串。 缓冲区溢出。 神秘的语法。我不知道有多少次我查到像atoi这样的东西,拍着我的额头,然后大喊“当然!”

编辑:如果我使用更多的库代码(就像我用套接字做的那样,但那些特别糟糕),我可能会想出更多的库代码,但我已经觉得我选择C语言是在作弊。许多语言的存在只是为了取C语言的好的部分,取代坏的部分,这有点像在徒劳无益。

其他回答

Ruby:

重要的空白。对于解释器,行尾=语句的结束,除非看起来语句应该继续(或者显式转义换行符)。 慢 在线文档不如Python的好(为了辩护,Python的很棒) 我刚才提到慢了吗?

Ruby是我最喜欢的语言,以下是我不喜欢的语言:

绿色线程+阻塞C库=巨大的失败 慢得令人痛苦 标准库本身与其使用bang!方法 模块包含+扩展是混乱的。 “开放类”不能是范围-我想添加一个String#dostuff,但我不希望泄漏到所有的第三方库 没有二进制部署打包解决方案。

TCL

这是我最喜欢的语言,几乎可以做任何事情。多年来,它已经(慢慢地,非常缓慢地)演变为解决大多数让我烦恼的事情。而且这门语言非常灵活,很容易实现语法来覆盖那些仍然困扰我的东西。但是语言中有一些东西是不能轻易改变的,只是打破了它的禅意:

Arrays (of the associative kind, what Perl calls hash) don't have proper value semantics. This makes them awkward to pass to and return from functions. Also, this means that they can't be nested. For this reason dicts (dictionaries) were invented but too late, the nice array access syntax: $array($foo) is now forever taken by stupid arrays for backwards compatibility. We're now stuck with: dict get $dict $foo which is much more verbose and to me feels less readable. No real closures. Though it can be emulated somewhat by globals or namespaces but that defeats the reason for closures in the first place. Although, I can't really see for now how closures can be implemented in a pure value semantics system. Teacup is hard to use and is not at all intuitive compared to all other repository tool out there. This is more ActiveState's fault than tcl-core and doesn't really break tcl's Zen when coding but it is still very annoying.

帕斯卡对象:

There's a lot of jumping back and forth in the file you're editing since the interface and implementation are split into two parts but still jammed into the same file. Dynamic indexing of arrays, strings start at 1, you specify the starting index when declaring fixed arrays and dynamically allocated arrays always start at 0. Classes and objects (not to speak of interfaces) are bolted on top of the language and among other things can't be stack allocated like records can. When calling functions without parameters the () are optional, leading to a lot of pain when you are dealing with function pointers or trying to refer to the result of a function using the function name. Parameter lists can't handle fixed array types or function pointer types without external type definitions.

这仅仅是一种语言,一个标准库的遗憾借口,而脆弱的IDE应该有自己的列表。

我使用Java,我最大的不满是字符串操作的低效率。当你使用+运算符时。说真的,难道编译器不能计算出我添加了多少字符串,然后在后台为我生成StringBuffer的东西吗?

通常,使用+的代码比StringBuffers操作序列更具可读性。

另外,我讨厌本机数组和集合框架之间的冗余。. toarray()的语法极其丑陋。
