2024-08-08 07:47:03 +00:00
< p > 在 C 语言发明之后约5年的时间之后（ ） ， < a href = "http://www.cs.princeton.edu/~bwk/" > Brian W. Kernighan< / a > 和 < a href = "http://genius.cat-v.org/dennis-ritchie/" > Dennis M. Ritchie< / a > 合作编写出版了C语言方面的经典教材《< a href = "http://s3-us-west-2.amazonaws.com/belllabs-microsite-dritchie/cbook/index.html" > The C Programming Language< / a > 》，该书被誉为 C 语言程序员的圣经，作者也被大家亲切地称为 < a href = "https://en.wikipedia.org/wiki/K%26R" > K& R< / a > 。同样在 Go 语言正式发布（ （ ， < a href = "https://github.com/adonovan" > Alan A. A. Donovan< / a > 和 < a href = "https://en.wikipedia.org/wiki/K%26R" > K& R< / a > 中的 < a href = "http://www.cs.princeton.edu/~bwk/" > Brian W. Kernighan< / a > 合作编写了Go语言方面的经典教材《< a href = "http://gopl.io" > The Go Programming Language< / a > 》。Go 语言被誉为 21 世纪的 C 语言，如果说 < a href = "https://en.wikipedia.org/wiki/K%26R" > K& R< / a > 所著的是圣经的旧约，那么 D& K 所著的必将成为圣经的新约。该书介绍了 Go 语言几乎全部特性，并且随着语言的深入层层递进，对每个细节都解读得非常细致，每一节内容都精彩不容错过，是广大 Gopher 的必读书目。大部分 Go 语言核心团队的成员都参与了该书校对工作，因此该书的质量是可以完全放心的。< / p >
2023-06-26 17:38:05 +00:00
< p > 同时，单凭阅读和学习其语法结构并不能真正地掌握一门编程语言，必须进行足够多的编程实践——亲自编写一些程序并研究学习别人写的程序。要从利用 Go 语言良好的特性使得程序模块化，充分利用 Go 的标准函数库以 Go 语言自己的风格来编写程序。书中包含了上百个精心挑选的习题，希望大家能先用自己的方式尝试完成习题，然后再参考官方给出的解决方案。< / p >
< p > 该书英文版约从 2015 年 10 月开始公开发售，其中日文版本最早参与翻译和审校（参考致谢部分）。在 2015 年 10 月，我们并不知道中文版是否会及时引进、将由哪家出版社引进、引进将由何人来翻译、何时能出版，这些信息都成了一个秘密。中国的 Go 语言社区是全球最大的Go语言社区， < a href = "http://www.amazon.cn/The-Go-Programming-Language-Donovan-Alan-A-A/dp/0134190440/" > 亚马逊价格314人民币< / a > 。补充：国内也即将出版英文版，< a href = "http://product.china-pub.com/4912464" > 价格79元< / a > ）。为了 Go 语言的学习和交流，大家决定合作免费翻译该书。< / p >
< p > 翻译工作从 2015 年 11 月 20 日前后开始，到 2016 年 1 月底初步完成，前后历时约 2 个月时间（在其它语言版本中，全球第一个完成翻译的，基本做到和原版同步）。其中，< a href = "https://github.com/chai2010" > chai2010< / a > 翻译了前言、第2 ~ 4章、第10 ~ 13章， < a href = "https://github.com/cch123" > Xargin< / a > 翻译了第1章、第6章、第8 ~ 9章， < a href = "https://github.com/CrazySssst" > CrazySssst< / a > 翻译了第5章， < a href = "https://github.com/foreversmart" > foreversmart< / a > 翻译了第7章， ， ， < a href = "https://github.com/golang-china/gopl-zh/issues" > Issue< / a > ，如果发现英文版原文在< a href = "http://www.gopl.io/errata.html" > 勘误< / a > 中未提到的任何错误，可以直接去< a href = "https://github.com/adonovan/gopl.io/" > 英文版项目< / a > 提交。< / p >
