Oberon：被忽视的瑰宝 [PDF]
Oberon – The Overlooked Jewel [pdf]
2011 — 2013，它一次次回到首页

导读
本文是一篇探讨 Oberon 操作系统与编程语言的论文，介绍这个由 Niklaus Wirth 设计、长期被忽视的系统。Oberon 将操作系统、编译器和语言设计融为一体，诸多理念——如早期 JIT 编译、基于文本的可点击交互、极简的模块化结构——都远远超前于时代。
为什么经久不衰：Oberon 展示了一种用安全系统编程语言构建完整操作系统的优雅路径，其极简而深远的设计从 JIT 到影响 Go 的方法绑定，至今仍在启发系统软件开发者。

Oberon 技术理念超前，作者发明了早期 JIT，且 Wirth 的多本著作至今仍极具参考价值。
我曾试用过 Oberon，它远远超前于时代。论文作者不仅发明了最早的 JIT 编译系统之一，而且对系统编程语言来说，能用鼠标点击执行代码（类似 Rob Pike 的 ACME 编辑器）这一能力至今仍无人实现。Oberon 上还尝试过许多新颖的研究想法，比如有篇叫「Active Text」的论文允许把视频放进代码注释。所有讲解细节的书都强烈推荐：Wirth 的编译器书是经典的轻松入门（Oberon-0 语法只需两页！），他的算法书有些描述别处找不到，而《Project Oberon》则包含对系统软件独一无二的论述，例如实现文本编辑器的最佳数据结构 PieceLinkText（比 rope-strings 早很多）。

I tried Oberon once and have to say that it was way ahead of its time. Not only did the author (of the linked paper) invent one of the first JIT compiled systems, but also the ability to execute code with a mouse click (similar to Rob Pike's ACME editor) is---for a systems programming language---still not available today. There were several novel research ideas tried for the Oberon system. I remember there was some paper called "Active Text" that allowed putting videos into code comments. (Probably that could have been done in Smalltalk, too.) Finally, all of the books explaining details are heartily recommended. Wirth's compiler book (referred to at HN several times) is a classic easy-going introduction (the Oberon-0 grammar fits on only two pages IIRC! [1]), his algorithm book (also available for download, also referred to multiple times at HN) has some of the nicest descriptions that I did not find anywhere else (showing a divide-and-conquer approach to computing the median [near the Quicksort treatment]; plus polyphase sort, which might be useful again in data centers), and finally the Project Oberon book contains some unique treatment on system software that is not easily found anywhere else. For example, it contains the details on what's called PieceLinkText, which is the (at least AFAIK) best data structure to implement a text editor and it's operations. (Predating rope-strings by a fair amount of time, too.) edit: [1]: just checked my own copy; Oberon-0's grammar actually fits on one page, the full Oberon grammar fits on two pages!

Project Oberon 一书在 550 页内附完整源码，清晰讲解编译器与操作系统设计。
《Project Oberon: The Design of an Operating System and Compiler》一书详细讲解了 Oberon 编译器和操作系统的设计。它不仅写得清楚、解释明晰，而且在不到 550 页的篇幅里包含了编译器和操作系统的完整源代码！我从这本书中学到了一些有趣的编译技术。

The book "Project Oberon: The Design of an Operating System and Compiler" http://www.amazon.com/Project-Oberon-Design-Operating-Compiler/dp/0201544288/ref=sr_1_1?ie=UTF8&qid=1366902572&sr=8-1&keywords=project+oberon contains a detailed explanation of the design for the Oberon compiler and operating system. Not only it is well written with clear explanations, but it also includes the full source code for the compiler and operating system in less than 550 pages! I learned some interesting compiler techniques from reading that book.
Oberon 证明安全语言可做 OS，其模块化 UI 设计可扩展，且影响了 Go 的方法绑定。
相当不错的系统，我大学时代还写过一个它的词法/语法分析器。它活生生证明了用安全的系统编程语言开发操作系统是可行的。Native Oberon 系统的使用体验很好，其 UI 概念映射到 Oberon 模块的方式使其具有很好的可扩展性。遗憾的是业界始终没有采用它。Go 中方法与类型关联的方式受到了 Oberon 语言家族的影响（参见 Component Pascal）。

Quite a nice system. I even wrote a lexer/parser for it back on my university days. It is the living proof that it is possible to use a safe systems programming language for operating system development. The Native Oberon system was quite nice to use in how the UI concepts would map to Oberon modules, as such it was quite extensible. Sadly, it never got picked up by the industry. The way methods are associated with types in Go has been influenced by Oberon language family (see Component Pascal).
Pascal/Oberon 系语言因用户少且分支碎片化而衰落，官方资源也显得荒废。
伴随 Borland Pascal 长大，我对 Pascal 及其衍生语言有感情。我喜欢用 BP 编程，也为 Pascal 衍生语言输给 C 衍生语言而有些不快。（我读过一些 Modula 3 的资料，对其模块系统颇感兴趣。）但用户少、碎片化严重（Borland Pascal/Delphi、Object Pascal、Component Pascal；Modula-2 和 Modula-3；Oberon、Oberon-2、Oberon-07、Active Oberon、Zonnon）。当所有这些语言加起来用户基数大概和 Common Lisp 一样「大」时，你该怎么选？而且 ETH 的 Oberon 网页看起来像废弃了一样。

Having grown up on Borland Pascal, I have a sentiment for Pascal and its derivatives. I enjoyed programming in BP, and I'm not too happy that Pascal derivatives lost their popularity to C derivatives. (I was reading a bit about Modula 3 and got quite intrigued by its module system.) But, users are few, fragmentation is high (Borland Pascal/Delphi, Object Pascal, Component Pascal; Modula-2 and Modula-3; Oberon, Oberon-2, Oberon-07, Active Oberon, Zonnon). How the heck are you supposed to choose when all those languages taken together have probaby about user base as "large" as that of common lisp? Plus, Oberon webpages at ETH look like abandoned.
