#!/bin/bash

if [ -f "go.mod" ];then
    # tmp_arr=()
    for line in $(<go.mod);
    do
        if [[ $line =~ git.zxl.com* ]];then
            tmp_arr[${#tmp_arr[*]}]=$line
        fi
    done
    sed -i '/git.zxl.com/d' go.mod
    for url in ${tmp_arr[@]};
    do
        go get $url@master
    done
