Automatically apply a go.mod compatible version on change directory

[mcandre]

When the user changes directories, automatically use a compatible Go version, or else warn the user that the Go version specified in go.mod is not installed.

I'm using the script below with zsh based on the nvm script.

You have to append the contents at the end of your .zshrc file.

load-gomod() {
  local go_version="$(gvm-prompt)"
  local gomod_path="go.mod"

  if [ -f "$gomod_path" ]; then
    local gomod_go_version="$(grep -oP 'go\W+(.*)$' ${gomod_path} | sed -e 's/go /go/')"
    if [ "$gomod_go_version" = "" ]; then
      gvm use system
    elif [ "$gomod_go_version" != "$go_version" ]; then
      local gomod_go_version_installed="$(gvm list | grep ${gomod_go_version})"
      if [ "$gomod_go_version_installed" = "" ]; then
        echo "trying to install ${gomod_go_version}"
        gvm install ${gomod_go_version}
      fi
      gvm use ${gomod_go_version}
    fi
  elif [ "$go_version" != "system" ]; then
    gvm use system
  fi
}

This is something that I would like to implement in the near future.
