Shell 函数实现Go语言多版本管理轻量级方案

golang solution multi-version

现有的工具方案

我的方案

优点:

  • 原生:基于 go 语言本身支持多版本的能力实现,可以下载任何官方发布的版本
  • 简单:shell 函数实现,直接集成到 bashrc 或 zshrc 中即可使用,无需额外配置
  • 可定制化:代码简单可根据自身需求定制

代码实现

####### GOLANG VERSION MANAGE FUNCTIONS ######
# ref: https://go.dev/doc/manage-install
function goinstall() {
 echo "Downloading go$1 ..."
 go install golang.org/dl/go$1@latest && go$1 download
}

function gouse() {
 gopath=$(go env GOPATH)
 if test -x ${gopath}/bin/go$1; then
  rm -f ${gopath}/bin/go
  echo "Relink go with go$1 ..."
  ln -s ${gopath}/bin/go$1 ${gopath}/bin/go
  echo "Done"
 else
  echo "Version $1 not installed"
 fi
}

function golist() {
 current=$(go version | awk '{print $3}' | cut -c3-)
 for v in $(ls $(go env GOPATH)/bin | grep -E 'go(\d.*)' | cut -c3-);
 do
  if [ $v = $current ]; then
   echo "$v (⇦ current)"
  else
   echo $v
  fi
 done
}

function gouninstall() {
 current=$(go version | awk '{print $3}' | cut -c3-)
 if [ $1 = $current ]; then
  echo "version $1 is actived, please change to another version first"
  return
 fi
 echo "Removing binary..."
 rm -f $(go env GOPATH)/bin/go$1
 echo "Removing sdk ..."
 rm -r ~/sdk/go$1
 echo "Done"
}

使用方式

  1. 将上面的代码粘贴到 ~/.bashrc (如果是zsh,则是 ~/.zshrc) 末尾,保存退出
  2. source ~/.bashrc 激活即可
