通过脚本生成launch.json可以实现个性化定制，一般在.vscode目录下有个launch.template.json，供脚本读取，然后替换掉其中<<< >>>的字符再生成launch.json。该脚本源码如下：

import os,sys,socket
import argparse

if __name__ == "__main__":
    print ("....[-*-]Start to create launch.json...")
    force_rebuild = False

    parser = argparse.ArgumentParser(description='Process lanch parameters.')
    parser.add_argument('--it', dest='it_project_name', type=str, default="MyProject_IT",
                    help='it project name to run.')
    parser.add_argument('-f', dest="force_rebuild", action="store_true", default=False,
                    help="force_rebuild")
    args = parser.parse_args()
    it_project_name = args.it_project_name
    force_rebuild = args.force_rebuild

    if os.path.isfile("launch.json"):
        print ("....[-*-]launch.json exists and force_rebuild is %s!"%force_rebuild)
        if not force_rebuild:
            print ("....[-*-]generator quits!")
            sys.exit(0)

    file_data = ""
    with open("launch.template.json", mode="r") as fr:
        file_data = fr.read()

    file_data = file_data.replace("<<<it_project_name>>>", it_project_name)

    my_name = socket.getfqdn(socket.gethostname(  ))
    my_addr = socket.gethostbyname(my_name)
    print ("....[-*-]local_ip_address = %s"%my_addr)

    file_data = file_data.replace("<<<local_ip_addr>>>", my_addr)

    with open("launch.json", mode="w") as fw:
        fw.write(file_data)

    print ("....[-*-]launch.json is created.")

    sys.exit(0)
