“Github”里的“hub”改用Go語(yǔ)言開發(fā)
剛剛過去的2014年是Go語(yǔ)言重要的一年,不僅版本升級(jí)到了1.4,而且Go語(yǔ)言的集成開發(fā)環(huán)境LiteIDE也發(fā)布了x26,還在云計(jì)算方便吸引力不是的注意力。雖然有很多程序員不喜歡Go語(yǔ)言,但每種語(yǔ)言都有直接的缺點(diǎn)和優(yōu)點(diǎn),這是很正常的事情。最重要的是取之長(zhǎng)、補(bǔ)己短。最近github宣布使用Go1.4重新開發(fā)了hub命令,就是要利用Go語(yǔ)言的長(zhǎng)處。
Github是世界上最大的代碼托管服務(wù),它是在于最近幾年迅速超過了SoruceForge,很大程度上得益于Linux創(chuàng)始人Linus的影響力,和Git中去中心化的思想。相信很多人都使用過git和github,但估計(jì)很少人知道這個(gè)等式:git + hub = github,hub是一個(gè)用來封裝git的工具,為其擴(kuò)展更多的功能和特性,是GitHub運(yùn)行起來更加快捷方便。
- $ 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當(dāng)作git的別名,這樣,當(dāng)你輸入$ git <command> 時(shí),你不僅能獲得git的所有功能,而且能增添很多附加特性。設(shè)置別名的方法是在你的.bash_profile文件放置下一行代碼:
- eval "$(hub alias -s)"
從2.2.0版本開始,hub開始改用Go語(yǔ)言開發(fā),主要原因是Go語(yǔ)言的高效。要想從源代碼安裝hub 2.x版本,你需要有一個(gè)Go語(yǔ)言開發(fā)環(huán)境,版本要在1.4以上:
- $ git clone https://github.com/github/hub.git
- $ cd hub
- $ ./script/build
- $ cp hub YOUR_BIN_PATH
hub2.x版本將對(duì)1.x版本保持最大的兼容。下面我里看一下hub命令提供了哪些額外的強(qiáng)大功能。
(下面這些代碼中假設(shè)你已經(jīng)做了git別名設(shè)置)
