golang 开发环境 配置 go语言 liteIDE

Mac:

* 下载go安装包

go语言中文网

** 通过源码编译安装需要先安装go1.4

wget https://studygolang.com/dl/golang/go1.10.3.src.tar.gz
tar xvzf go1.10.3.src.tar.gz -C .
cd ./go/src/
./make.bash

Building Go cmd/dist using /Users/Mch/go1.4.
ERROR: Cannot find /Users/Mch/go1.4/bin/go.
Set $GOROOT_BOOTSTRAP to a working Go tree >= Go 1.4.

** 直接用安装包安装

wget https://studygolang.com/dl/golang/go1.10.3.darwin-amd64.pkg
if [ ! -d /opt ]; then mkdir /opt; else echo "Directory /opt already exists"; fi
sudo installer -pkg go1.10.3.darwin-amd64.pkg -target /opt # 这里出错了 没解决

** 用brew安装

brew install go

==> Caveats
A valid GOPATH is required to use the `go get` command.
If $GOPATH is not specified, $HOME/go will be used by default:
https://golang.org/doc/code.html#GOPATH

You may wish to add the GOROOT-based install location to your PATH:
export PATH=$PATH:/usr/local/opt/go/libexec/bin
==> Summary
/usr/local/Cellar/go/1.10.3: 8,170 files, 336.8MB

* 配置环境变量 GOROOT, GOBIN, PATH, GOPATH

emacs -nw ~/.bash_profile

　　~/.bash_profile 文件如下:

export MAVEN=/Users/Mch/apache-maven-3.5.0/bin
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_91.jdk/Contents/Home
# export JAVA_HOME=/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
export CLASSPATH=${JAVA_HOME}/lib/

export GOROOT=/usr/local/Cellar/go/1.10.3/libexec
export GOBIN=${GOROOT}/bin
export GOPATH=${HOME}/Code/golang

export PATH=/Applications/XAMPP/bin:${GOBIN}:${PATH}:${JAVA_HOME}/bin:$MAVEN:/usr/local/apache-tomcat-9.0.0.M26/bin:~/.composer/vendor/bin:/opt/gradle-3.5.1/bin

# Tell ls to be colourful
export CLICOLOR=1
export LSCOLORS=Exfxcxdxbxegedabagacad

# Tell grep to highlight matches
export GREP_OPTIONS='--color=auto'

# export PATH="$HOME/.jenv/bin:$PATH"
# eval "$(jenv init -)"

　　

# 使配置生效
. ~/.bash_profile
# 查看版本
go version

　　go version go1.10.3 darwin/amd64

* 下载liteide

golang中国  https://www.golangtc.com/download/liteide

wget https://www.golangtc.com/static/liteide/X32.1/liteidex32.1.macosx-qt4.zip
unzip liteidex32.1.macosx-qt4.zip -d .
sudo mv liteide /opt/
sudo chown -hR `whoami`:staff /opt/liteide/
sed -n '/^export PATH=.*$/p' ~/.bash_profile
echo 'export PATH=${PATH}:/opt/liteide/LiteIDE.app/Contents/MacOS' >> ~/.bash_profile
. ~/.bash_profile
which liteIDE
liteIDE &

　　

* 安装gdb [optional]

brew install gdb
which gdb
# /usr/local/bin/gdb

　　

* 配置liteIDE system.env

# launch liteIDE
/opt/liteide/LiteIDE.app/Contents/MacOS/LiteIDE

　　

View => Edit Current Environment

# native compiler darwin amd64

export GOROOT=/usr/local/Cellar/go/1.10.3/libexec
export GOBIN=${GOROOT}/bin
export GOPATH=${HOME}/Code/golang
GOARCH=amd64
GOOS=darwin
CGO_ENABLED=1

PATH=$GOBIN:$GOPATH:/bin:$PATH

LITEIDE_TERM=/usr/bin/open

LITEIDE_EXEC=/usr/X11R6/bin/xterm
LITEIDE_EXECOPT=-e

　　

　　

* 测试安装环境

File => New... => Go1 Command Project => Name: Greedy => OK

对于默认的输出helloworld的项目

按 command + R， 编译并运行

* 启动godoc api文档服务

godoc -http=:6060 &

　用浏览器打开 http://localhost:6060/ 一些参考手册链接打不开

go get golang.org/x/blog

package golang.org/x/blog: unrecognized import path "golang.org/x/blog" (https fetch: Get https://golang.org/x/blog?go-get=1: dial tcp 216.239.37.1:443: i/o timeout)

博客下载超时，需要安装gopm

go get -u github.com/gpmgo/gopm
ls $GOBIN
# go godoc gofmt gopm
# gopm安装成功

　

用gopm安装 golang.org/x/blog

if [ ! -d $GOPATH/bin ]; then mkdir $GOPATH/bin; fi
gopm bin -d $GOPATH/bin golang.org/x/blog

　　output:

[GOPM] 07-29 11:50:20 [ WARN] Getting imports: no buildable Go source files in /var/folders/60/qw4hdqc50m32mwxr054b9j200000gn/T/359841253/src/golang.org/x/tools
[GOPM] 07-29 11:50:20 [ WARN] Getting imports: no buildable Go source files in /Users/Mch/Code/golang/.vendor/src/golang.org/x/tools
[GOPM] 07-29 11:50:21 [FATAL] Previous steps weren't successful or the project does not contain main package

　　出错了

cd $GOPATH/src/github.com/github.com/gpmgo/gopm
go build .
go install
gopm install golang.org/x/blog # 这个错误

　　[GOPM] 07-29 12:00:54 [FATAL] fail to list imports: fail to get imports(/Users/Mch/Code/golang): import "/Users/Mch/Code/golang": cannot import absolute path

rm -f $GOBIN/gopm　　

　　 再将$GOPATH/bin添加到PATH环境变量

which gopm

　　# /Users/Mch/Code/golang/bin/gopm

# 把gopm安装到$GOPATH/bin， 再试

gopm get -g golang.org/x/blog  # go get golang.org/x/blog 用gopm替换go

　　重启godoc服务

lsof -i:6060 | awk '{if(NR>1) {print $2}}' | xargs kill -SIGTERM
godoc -http=:6060

　　可以查看手册了 http://localhost:6060/blog/go-slices-usage-and-internals

* 写一个字符串反转的例子

参考手册 http://zhanghum:6060/pkg/strings/#Split

(zhanghum是我的主机名)

// String project main.go
package main

import (
	"fmt"
	"strings"
)

func strrev(s string) string {
	a := strings.Split(s, "")
	i := 0
	j := len(a) - 1
	for i < j {
		tmp := a[i]
		a[i] = a[j]
		a[j] = tmp
		i++
		j--
	}
	return strings.Join(a, "")
}

func main() {
	s := strrev("Hello world!")
	fmt.Println(s)
}

　　output:
