### CPPS腳本是一個開源的腳本語言 [![star](https://gitee.com/cppsscript/cpps/badge/star.svg?theme=dark)](https://gitee.com/cppsscript/cpps/stargazers)[![Github stars](https://img.shields.io/github/stars/johnsonyl/cpps.svg?style=plastic&logo=appveyor)](https://github.com/johnsonyl/cpps) 作者QQ：88481106 郵箱：88481106@qq.com QQ群：282081601 github: - https://github.com/johnsonyl/cpps 2020-12-11 更新 - 1.增加一個基于cpps的MVC框架.目錄 bin/webbase 2020-12-10 更新 - 1. 修復[]偶發找不到變量的BUG. 2. 修復#include 對應文件與行號不一致的BUG 3. 更新socket::httpserver path都以小寫來檢測 4. 增加http模塊 downloader類 5. cppsc 支持部分命令可以查看-h 或 -help , 例子 cppsc -h 6. linux walk支持. 7. mysql模塊增加affected_rows 獲取最后一次執行影響行數 8. 取消cppsc 可繼續執行語句功能. 9. 修改cppsc默認當前目錄main.cpp 10. 修改cppsc 為建立軟連接模式 2020-12-9 更新 - 1.增加compress庫 1.1 支持 zlib gzip 解壓與壓縮 1.2 增加 zip ,tar, tar,gz 的文件壓縮與解壓縮. 注: bz2 lzma 暫時未支持.后續更新. ``` system("chcp 65001"); //use utf8 string #import "compress" var srcstr = "123456789"; //zlib var tarstr = zlib.compress(srcstr); println(string.length(tarstr)); var srcstr2 = zlib.decompress(tarstr); println(srcstr2); println(zlib.adler32(srcstr2)); println(zlib.crc32(srcstr2)); println(zlib.ZLIB_VERSION); println(zlib.ZLIB_RUNTIME_VERSION()); //gzip // var tarstr = gzip.compress(srcstr); println(string.length(tarstr)); var srcstr2 = gzip.decompress(tarstr); println(srcstr2); // //zipfile var file = zipfile.open("test.zip"); file.extractall(); //輸出個別需要文件 foreach(var info: file.infolist()){ if(!info.is_dir()){ var buffer = file.read(info.filename()); if(buffer){ var filename = io.getfilename(info.filename()); println(filename); var file = io.fopen(filename,"wb+"); if(file){ println("save ok"); io.fwrite(file,buffer); io.fclose(file); } } } } //zip 追加文件 var file = zipfile.open("test2.zip","","a"); file.write("client.cpp"); file.close(); //tarfile //tar解壓縮 var file = tarfile.open("test.tar","r",10240000); file.extractall(); //tar.gz 解壓縮 var file = tarfile.open("test.tar.gz","r:gz",10240000); file.extractall(); //tar.gz 寫入 var file = tarfile.open("test2.tar.gz","x:gz",10240000); var fileinfo = file.gettarinfo("server.cpp"); file.addfile(fileinfo); file.close(); ``` 2020-12-6 更新 - 1.增加協程內置模塊 asyncio ``` //無需import asyncio... async var test() { println("do test function"); await asyncio.sleep(2000); println("do test function done"); return "test"; } async var test1() { println("do test1 function"); await asyncio.sleep(1000); println("do test1 function done"); return "test1"; } var test_call_back(var task,var context) { println(task.get_name()); println(context); } async var main(){ var task1 = asyncio.create_task(test()); task1.set_name("自定義名字用于區分"); task1.add_done_callback(test_call_back,"自定義context內容"); var task2 = asyncio.create_task(test1()); var ret = await asyncio.wait(task1); if(ret.timeout()) { println("task1 was timeouted."); } println("state:{ret.state()}"); println(ret.result()); println(await task2); task1.cleanup();// asyncio.wait or asyncio.wait_for need cleanup. //task2.cleanup(); // crash here.. await will cleanup it. } asyncio.run(main()); ``` 2020-12-5 更新 - 1.增加lambda閉包.類似js.解決了內存泄露問題. 2. 優化cpps運行速度.cpps_value減少一個8字節指針,理論又提速了. ``` var outer() { var result = []; result.resize(10); for (var i = 0; i<10;i++){ result[i] = [](var num){ return [](){ println(num); // 此時訪問的num，是上層函數執行環境的num，數組有10個函數對象，每個對象的執行環境下的number都不一樣 }; }(i); } return result; } var l = outer(); foreach(var n : l) { n(); } ``` 2020-12-2 更新 - 1.增加logging模塊 1.1 支持 logging.StreamHandler logging.FileHandler logging.handlers.RotatingFileHandler logging.handlers.TimedRotatingFileHandler 2.修復已知BUG *** 基礎版 ``` #import "logging" logging.create({level:logging.DEBUG, format:'[%(levelname)s][%(asctime)s][%(filename)s:%(lineno)d]%(message)s', filename:'log/myapp.log', filemode:'ab+'}); var logger = logging.getlogger(''); var streamhandler = new logging::StreamHandler(); streamhandler.setlevel(logging.DEBUG); streamhandler.setformatter('[%(levelname)s][%(asctime)s][%(filename)s:%(lineno)d]%(message)s'); streamhandler.setcolor([1,2,3,4,5]); logger.addhandler(streamhandler); logger.debug("debug"); logger.info("info"); logger.warning("warning"); logger.error("error"); logger.critical("critical"); ``` *** 旗艦版(配置版) ``` #import "logging" var simple_format = '[%(levelname)s][%(asctime)s][%(filename)s:%(lineno)d]%(message)s'; var standard_format = '[%(asctime)s][task_id:%(name)s][%(filename)s:%(lineno)d][%(levelname)s][%(message)s]'; var LOGGING_CONFIG = { version: 1, // 版本號 disable_existing_loggers: false, //　固定寫法 formatters: { standard: { format: standard_format }, simple: { format: simple_format }, }, filters: {}, handlers: { //打印到終端的日志 sh: { level: 'DEBUG', class: 'logging.StreamHandler', // 打印到屏幕 color: [5,4,3,2,1] , // DEBUG,INFO,WARNING,ERROR,CRITICAL 顏色 formatter: 'simple' }, fh: { level: 'DEBUG', class: 'logging.handlers.TimedRotatingFileHandler', // 打印到屏幕 formatter: 'standard', filename: "log/log.txt", mode: "ab+", backupCount:5, //保留5個 when:"S", //秒 interval:5 //5秒 }, }, loggers: { root: { //root 為默認 handlers: ['sh','fh'], //這里把上面定義的兩個handler都加上，即log數據既寫入文件又打印到屏幕 level: 'DEBUG', propagate: true, // 向上（更高level的logger）傳遞 }, }, } logging.create_with_config(LOGGING_CONFIG); while(true){ logging.debug("debug"); logging.info("info"); logging.warning("warning"); logging.error("error"); logging.critical("critical"); sleep(2000); } ``` 2020-12-1 更新 - 1.修復更新的BUG. 2.增加console基礎庫 3.增加讀取傳入參數 4.增加文本地址讀取順序. 2020-11-30 更新 - 1.增加foreach xrange. 2.優化cpps速度 ``` foreach(var i : xrange(0,999)) { println(i); } foreach(var i : nrange(0,999,3)) //每次遞增3 { println(i); } ``` 2020-11-29 更新 - 1.花了幾天的時間優化cpps. 提升運行速度幾十倍. 不過優化的還是不夠. 大概速度和python 差不多. 目標是lua的速度.以前瞧不起lua,真正運行起來才知道lua的速度不是蓋的.沒有使用JIT就可以達到這樣的速度.優化是真的NB.但是這次更新估計會有很多BUG.特此記錄一下. 2020-11-24 更新 - 1.增加hashlib庫 md5 sha1 sha224 sha256 sha384 sha512 2.http模塊增加urlencode,urldecode 3.增加字符串encoding gbk<->utf8 ``` system("chcp 65001");

println(utf8);//鎴戞槸涓枃 s = encoding.encode(utf8,encoding.GBK); println(s);//我是中文 ``` 2020-11-23 更新 - 1.增加base64模塊 2.增加mysql模塊 3.優化cpps 4.修復字符串format 調用函數找不到變量的BUG. ``` //base64例子 system("chcp 65001"); //use utf8 string import ["base64"]; var s = "abc"; println("source:{s}"); var encode_s = base64.encode(s); println("encode_s:{encode_s}"); var deocde_s = base64.decode(encode_s); println("deocde_s:{deocde_s}"); ``` ``` //mysql例子 import ["mysql"]; var option = new MysqlOption() { db = "dbname", host = "127.0.0.1", user = "root", passwd = "*******", prot = 3306, isreconnect = true } var conn = mysql.connect(option);

println("username:"..record.get("username")); println("userpwd:"..record.get("userpwd")); } } ``` 2020-11-22 更新2 - 1.增加http模塊 httprequest類 ``` system("chcp 65001"); //use utf8 string import ["http"]; var request = new http::httprequest(); request.setcookiesfile("cookies.txt"); //request.setproxy(httpproxy.SOCK5,"192.168.1.166:25455"); //request.setproxyaccount("johnsonyl","mima"); request.addheaders({User-Agent:"cppsrequest/1.1.0"});

var age = 32; } var a = new A(); var s = "my name is {a.name} , i'm {a.age} years old."; println(s); 輸出： [Cpps 1.2.0 Copyright (C) 2015-2020 By Johnson, Pub-test] my name is john , i'm 32 years old. > 值得注意： { 與 } 需要使用 \{ 與 \} 來特殊處理了。 ~~~ 2020-11-10 更新2 - 1.修復父類構造函數執行順序 2.增加調用父類虛函數的功能 3.增加父類對名空間的支持 4.foreach 還是修改成C++ 方式。并且 : 后為表達式 ~~~ foreach(var item : [1,2]) { println(item); foreach(var item2 : [3,4]) { println(item2); } } foreach(var item : {a:1,b:"2"}) { println(item.first()); println(item.second()); } var b = {a:1,b:"2"}; foreach(var item : b) { println(item.first());

b.test(); 輸出： [Cpps 1.2.0 Copyright (C) 2015-2020 By Johnson, Pub-test] C class A class:john B class B->test() 32 C->test() > ~~~ 2020-11-10 更新 - 重寫foreach 老版本使用lambda 方式，很不好。修改成見上方新方法增加 new 時設置變量功能類似c# ~~~ class A { var name; var age; } var a = new A(){ name = "john", age = 32 } ~~~ 2020-1-28 更新 - 新年快樂~~ happy new year! 1.今天恢復了對linux gcc++ 的編譯支持。對linux實在不太熟悉。一堆警告。很糟心。 2.增加make lib 與 make install指令 3.cpps 默認工作目錄為指定文件目錄。 2020-1-21 更新 - 解決了&&與|| 未按照順序執行導致邏輯錯誤的BUG。 2020-1-20 更新 - 增加const的支持。 const var abc = "10"; //不可修改。 2020-1-19 更新 - 1.增加調用函數參數支持到11個 2.增加支持構造函數。 c++ 部分需要注冊一個名為constructor的函數當構造函數 3.并且修復多層名空間有錯誤的BUG。 4.增加類似js 當創建出匿名函數后并且調用的方法例子： ~~~ [](var a){ println(a); }(123); ~~~ 2019-12-7 更新 - 之前老版本是在函數結束后才調用GC，那么如果想在主函數寫一個死循環執行邏輯就會造成內存永不會被GC釋放，現在會在符合內存大小等限制情況下調用GC釋放內存了。具體大小見CPPS\_GEN0\_CHECKSIZE ，等宏定義。 2019-11-01 - foreach 增加break操作這2年其實也更新了好多東西沒有同步而已。可以在代碼中自行查閱 2017-8-31 - 1.新增CPPS內部函數resume() 在內部拋出thorw異常的時候使用resume可解決GC異常問題 2.新增assert函數 3.新增部分數學庫 4.新增CPPS定義庫變量類似math.pi 5.修復vector變量[] 括號內不能使用公式的BUG 6.新增string.format字符串格式化功能 7.修復三元表達式與namespace在某些情況下沖突的問題 8.增加16進制變量值 9.增加svn服務器下載
