Sublime 之 Go

操作环境:Win7 64位

前提:

1. 已安装GO并设置好环境变量后。(例子:我的GOROOT=C:/Go ;GOPATH=D:/gogo;Path中已经添加%GOPATH%\bin)
2. 如果是第二次安装并配置Sublime则需要把之前的Sublime文件删除干净,包括系统盘的有关sublime文件都删除干净,以免出现额外的问题。
3. 已安装Git

1. 下载Sublime Text3

下载连接:https://www.sublimetext.com

2. 安装Package Control

按下:ctrl+`,调出控制台,复制相关代码,粘贴进控制台,按回车键。

相关代码(只适用于Sublime Text3):

import urllib.request,os,hashlib; h = '6f4c264a24d933ce70df5dedcf1dcaee' + 'ebe013ee18cced0ef93d5f746d80ef60'; pf = 'Package Control.sublime-package'; ipp = sublime.installed_packages_path(); urllib.request.install_opener( urllib.request.build_opener( urllib.request.ProxyHandler()) ); by = urllib.request.urlopen( 'http://packagecontrol.io/' + pf.replace(' ', '%20')).read(); dh = hashlib.sha256(by).hexdigest(); print('Error validating download (got %s instead of %s), please try manual install' % (dh, h)) if dh != h else open(os.path.join( ipp, pf), 'wb' ).write(by)

参考:https://packagecontrol.io/installation#st3

安装完毕后,关闭sublime,再打开,点击Preferences,出现Package Control则安装成功。

3.安装插件

3.1 GoSublime
(作用:补全代码、提示错误、提示改动等功能)

下载地址:https://github.com/DisposaBoy/GoSublime

方法1: 用git clone命令获取,应该会获得一个GoSublime的文件夹。把该文件夹拷贝到sublime的包位置,也就是打开sublime - Preferences - Browse Packages...,将该文件粘贴进来)。

方法2:(建议使用方法1)下载压缩包,解压后会得到一个长名字的文件夹,把文件名改为GoSublime,再把该文件夹移动到安装sublime包的位置,也就是打开sublime - Preferences - Browse Packages...,将文件粘贴进该位置)

然后,关闭sublime,再打开sublime。(我发现:这时GOPATH的bin文件夹内生成一个margo.sublime可运行文件)

情况1:如果出现该情况,就是需要调整Margo文件。

(如果没出现这个情况则说明正常)

依次按快捷键 ctrl+.,ctrl+x调出margo.go
复制以下代码,并替换原有代码。

package margo
import (
 "margo.sh/golang"
 "margo.sh/mg"
 "time"
)
// Margo is the entry-point to margo
func Margo(m mg.Args) {
 // See the documentation for `mg.Reducer`
 // comments beginning with `gs:` denote features that replace old GoSublime settings
 // add our reducers (margo plugins) to the store
 // they are run in the specified order
 // and should ideally not block for more than a couple milliseconds
 m.Use(
 // MOTD keeps you updated about new versions and important announcements
 //
 // It adds a new command `motd.sync` available via the UserCmd palette as `Sync MOTD`
 //
 // Interval can be set in order to enable automatic update fetching.
 //
 // When new updates are found, it displays the message in the status bar
 // e.g. `★ margo.sh/cl/18.09.14 ★` a url where you see the upcoming changes before updating
 //
 // It sends the following data to the url https://api.margo.sh/motd.json:
 // * current editor plugin name e.g. `?client=gosublime`
 // this tells us which editor plugin's changelog to check
 // * current editor plugin version e.g. `?tag=r18.09.14-1`
 // this allows us to determine if there any updates
 // * whether or not this is the first request of the day e.g. `?firstHit=1`
 // this allows us to get an estimated count of active users without storing
 // any personally identifiable data
 //
 // No other data is sent. For more info contact privacy at kuroku.io

关闭sublime后,重启。
没有出现以上情况则说明安装成功。

参考:https://www.jianshu.com/p/1aaaf18f4adc

在设置中添加以下代码:

{
 "env":{
 "GOPATH":"E:/gogo",
 "GOROOT":"C:/Go",
 }
}

(我没设置以上代码貌似也没出现什么问题。前提是之前的go安装和设置环境变量,我已经设置过了,应该sublime的默认设置会识别到。)

3.2 Goimports(它是一座大坑,爬过这个大坑有巨大的成就感。不把编辑器弄舒服以后怎么好好写代码呢?!所以希望小白的我们可以通过这个过程磨炼下耐心。)
作用:自动添加包,非常有用!

1. 由于网络原因无法直接下载goimports,需要先下载gopm包。
   打开git Bash Here,输入如下代码:

go get -v github.com/gpmgo/gopm

安装完成后,你会发现在:
1.1 GOPATH\src文件夹中看到github文件夹,以及很多文件。
1.2 GOPATH\bin文件夹中看到gopm的运行文件。

2. 下载goimports
   在git bash here中输入以下命令

gopm get -g -v -u golang.org/x/tools/cmd/goimports

安装完成后GOPATH\src文件夹中看到golang.org文件夹,里面有很多文件。

如果出现安装不了相应的包,或者显示网络没有链接,则都说明不正确。

出现这个为安装正常

(当然一切的目标是下载到goimports包,如果你有办法下到包即可。可以参考链接:gopm.io,下载你需要的包,当然也有golang.org/x/tools包)

3. 安装goimports

go install golang.org/x/tools/cmd/goimports

安装完成后,在GOPATH/bin中你会看到goimports的可运行文件。

4.测试运行
打开sublime,调出marge.go(快捷键按ctrl+. ctrl+x),按照图片进行修改。

保存修改后,关闭。
再打开一个go文件,点击保存(ctrl+s),可以看到import中会自动添加调用的包,并且会调整代码格式,这真是个非常好的插件。
(灵感来自与这篇文章,《Go语言环境配置 Sublime Text + GoSublime+ gocode + MarGo组》,看来后隐约觉得margo.go很重要,所以抱着在margo里改改代码试试,结果还真成功了。虽然这篇文章的内容我没怎么看,但是给了我一个灵感,让我想到再去margo试试,这个很重要。可以仔细读下margo中关于goimports的描述。)

如果你的没反应,再试试:打开Sublime-Preferences-Package Settings-GoSublime-Settings-User,输入以下代码

{
 "fmt_cmd": ["goimports"],
 "env": {
 "GOPATH": "/your/gopath/here" //输入你的GOPATH,如D:/gogo
 }
}

(以上设置我也没用到,如果你的goimports没有起作用可以试试。)

参考链接:(最后貌似没用上,但你也需要多查看资料,多试试,应该得这样)

1. .bash_profile 文件改坏了,什么命令都用不了了(https://blog.csdn.net/qq_16177481/article/details/55518267
   )
   (这个是查错的资料)

2. go环境变量配置 (GOROOT和GOPATH)
   (https://www.jianshu.com/p/4e699ff478a5
   )

3. goimports
   https://blog.csdn.net/geyujiao0828/article/details/89472658

3.3 Gotests
打开sublime,Preferences-Package Control-Install Package-输入Gotests,点击安装。
(研究好了再补充这个test怎么用)
