Linux:“Github”里的“hub”改用Go语言开发

Linux scott 163℃ 0评论

刚刚过去的2014年是Go语言重要的一年,不仅版本升级到了1.4,而且Go语言的集成开发环境LiteIDE也发布了x26,还在云计算方便吸引力不是的注意力。虽然有很多程序员不喜欢Go语言,但每种语言都有直接的缺点和优点,这是很正常的事情。最重要的是取之长、补己短。最近github宣布使用Go1.4重新开发了hub命令,就是要利用Go语言的长处。

Linux:“Github”里的“hub”改用Go语言开发

Github是世界上最大的代码托管服务,它是在于最近几年迅速超过了SoruceForge,很大程度上得益于Linux创始人Linus的影响力,和Git中去中心化的思想。相信很多人都使用过git和github,但估计很少人知道这个等式:git + hub = github,hub是一个用来封装git的工具,为其扩展更多的功能和特性,是GitHub运行起来更加快捷方便。

$ hub clone rtomayko/tilt

# expands to:
$ git clone git://github.com/rtomayko/tilt.git

hub命令的最佳使用方法是当作git的别名,这样,当你输入$ git  时,你不仅能获得git的所有功能,而且能增添很多附加特性。设置别名的方法是在你的.bash_profile文件放置下一行代码:

eval "$(hub alias -s)"

从2.2.0版本开始,hub开始改用Go语言开发,主要原因是Go语言的高效。要想从源代码安装hub 2.x版本,你需要有一个Go语言开发环境,版本要在1.4以上:

$ git clone https://github.com/github/hub.git
$ cd hub
$ ./script/build
$ cp hub 你的BIN目录

hub2.x版本将对1.x版本保持最大的兼容。下面我里看一下hub命令提供了哪些额外的强大功能。

(下面这些代码中假设你已经做了git别名设置)
