如何快速查看一个golang项目的总体结构？

脚本如下

#!/usr/bin/env bash
[[ -n $DEBUG ]] && set -x
set -ou pipefail

useage(){
  cat <<"EOF"
USAGE:
    gop.sh SRCPATH
EOF
}

exit_err() {
   echo >&2 "${1}"
   exit 1
}

if [ $# -ne 1 ];then
    useage
    exit
fi

SRCPATH=$1
if [ ! -d  "${SRCPATH}" ];then
    echo "${SRCPATH} is not a dir"
    exit
fi

cd "${SRCPATH}" || return

red='\033[0;31m'
plain='\033[0m'

info(){
    echo -ne "\n${red}$1：${plain}\n"
}

filenovendor(){
    find . -type f -name "$1" -not -path "./vendor/*"
}

grepnovendor(){
    grep --exclude-dir=vendor --include="$1" -Por "$2"
}

grepnovendorz(){
    grep --exclude-dir=vendor --include="$1" -Porz "$2"
}
