Lua调用脚本文件(不存在则新建脚本文件)

1.代码

local status, calParaFun = pcall(require, calParaFileName)
if not status then -- 如果模块加载失败则创建脚本文件
    local file = io.open(calParaFileName..".lua", "w")
    if file then
        file:write("-- 计算参数:"..name.."\n"..
        "local ModuleInputParas = require('InputPara/InputParas')\n"..
        "local ModulePublicParas = require('PublicPara/PublicParas')\n"..
        "local function exec()\n"..
        "    return nil\n"..
        "end\n"..
        "return exec\n"
        )
        file:close()
    else
        print("无法创建公共参数拟合算法文件")
    end
else              -- 如果模块加载成功则执行需要的操作
    print("old", name, publicParas[name])

end
