csvの加工
ちょっと進化した。
import csv import pprint import sys import os import glob # usage # python3 transErrorMessage.py def replaceRet(txt: str): return txt.replace("\n", "\\n") def wrapDQ(txt): return "\""+txt+"\"" surfix = "_SEMISELF" def main(filepath): if len(filepath)>0: transFile(filepath) return l = glob.glob("./*.csv") for f in l: transFile(f) return def transFile(filePath): translatedText = transTexts(filePath) filenameWithExt = os.path.basename(filePath) filename = os.path.splitext(filenameWithExt)[0] newfilepath = "./out/error_"+filename+".csv" # フォルダなければ作る file_path = os.path.dirname(newfilepath) if not os.path.exists(file_path): os.makedirs(file_path) with open(newfilepath,"w") as f: f.write(translatedText) def transTexts(filePath): returnText = "" with open(filePath) as f: # print(f.read()) reader = csv.reader(f) skip = True for row in reader: # print(row[0]) if len(row)<=5:# row[5]までつかうので continue if skip: if row[0] == "No": skip = False continue else: continue message = wrapDQ(replaceRet(row[4])) message_SS = wrapDQ(replaceRet(row[5])) text = wrapDQ(row[1]) + " = " + message + ";"+"\n" text_ss = wrapDQ(row[1]+surfix) + " = " + message_SS + ";"+"\n" returnText = returnText + text + text_ss return returnText # 実行部 filepath = "" if len(sys.argv)>2: filepath = sys.argv[1] main(filepath)
csvの加工
import csv
import pprint
import sys
# usage
# python3 transErrorMessage.py a.csv
def replaceRet(txt:str):
return txt.replace("\n","\\n")
def wrapDQ(txt):
return "\""+txt+"\""
surfix = "_hoge"
filename = sys.argv[1]
with open("./"+filename) as f:
# print(f.read())
reader = csv.reader(f)
skip = True;
for row in reader:
# print(row[0])
if skip:
if row[0] == "No":
skip = False
continue
else:
continue
message = wrapDQ(replaceRet(row[4]))
message_SS = wrapDQ(replaceRet(row[5]))
print(wrapDQ(row[1]) + " = " + message +";")
print(wrapDQ(row[1]+surfix) + " = " + message_SS +";")
express-generator-typescript
```cterm
npm install express-generator-typescript
```
作成
```cterm
npx express-generator-typescript "hello-app"
```
hello-appの中に入って実行
```cterm
cd hello-app
npm run start-dev
```
hello express
expressをinstallしておく
npm install express
typeも
npm install @types/express
import express from "express"; var app = express(); app.get("/", (req, res) => { return res.send("Hello World!"); }); app.listen(3001, () => { console.log("app listening on port 3001"); });
hello node
nodeのtypeを入れておく。
npm install @types/node
import * as http from "http" let server:http.Server = http.createServer((req:http.IncomingMessage, res:http.ServerResponse) => { res.writeHead(200, {'Content-Type':'text/plain'}); res.write("Hello World!"); res.end(); }); server.listen(3001); console.log("Server start at http://localhost:3001/");
これでlocalhost:3001でhello worldできる。
abc
バージョン確認
node -v v10.16.0 npm -v 6.9.0
typescriptのコンフィグファイル作成
tsc --init
npm開始
npm init
typescript実験用にhello.ts作成
console.log("hello")
トランスパイル
tsc
試しに実行してみる。
node hello.js
jsの吐き出し先をdistフォルダに変更する。tsconfigで
"outDir": "./dist", /* Redirect output structure to the directory. */
のように設定しておく。
文字横に画像
試行錯誤の結果次のようになった。
+ (NSAttributedString *)backSymbol { UIImage *image = [UIImage imageNamed:@"backbutton"]; NSTextAttachment *attachment = [[NSTextAttachment alloc] init]; attachment.image = image; NSMutableAttributedString *ret = [[NSMutableAttributedString alloc] init]; UIFont *font = [UIFont systemFontOfSize:17.0]; CGSize size = CGSizeMake(font.lineHeight * image.size.width/image.size.height, font.lineHeight); CGFloat y = round(font.capHeight - size.height)/2; [attachment setBounds:CGRectMake(-size.width*1/4, y, size.width, size.height)]; NSAttributedString *back = [NSMutableAttributedString attributedStringWithAttachment:attachment]; [ret appendAttributedString:back]; // NSMutableAttributedString *back = [[NSMutableAttributedString alloc] initWithString:@"＜"]; [ret addAttribute:NSFontAttributeName value:[UIFont boldSystemFontOfSize:21.0] range:NSMakeRange(0,back.length)]; return ret; }

delayする実験
#include <iostream> #include "rx-includes.hpp" class Man { public: Man(); ~Man(); void hello(); private: int age; std::string name; }; template <typename T> class AbstBase { public: T hoge; }; class FuncClass { public: FuncClass() : connectStateOb(std::shared_ptr<rxcpp::subjects::behavior<bool>>::make_shared(true)){ }; ~FuncClass(){} std::shared_ptr<rxcpp::subjects::behavior<bool>> connectStateOb; void poi(); rxcpp::observable<std::string> connect(); rxcpp::observable<std::string> disscconnect(); }; class Base : public AbstBase<Man>, public FuncClass { public: Base() : FuncClass(){}; ~Base(){}; }; class Conc: Base { public: Conc(): Base(){ }; ~Conc(){ std::cout << " ** deconstruction Conc **" << std::endl; }; rxcpp::observable<std::string> rxtest(); void log(std::string txt); };
#include "man.hpp" #include <chrono> Man::Man(): name("hoge"), age(0) { } Man::~Man() { std::cout << " ** desconstructe Man **" << std::endl; } void Man::hello() { std::cout << " ** hello **" << std::endl; } void FuncClass::poi() { std::cout << " ** poi **" << std::endl; } rxcpp::observable<std::string> FuncClass::connect() { rxcpp::observable<int> a = rxcpp::observable<>::just(0) .delay(std::chrono::milliseconds(1000)); rxcpp::observable<std::string> b = a.flat_map([=](auto x) { rxcpp::observable<std::string> c = rxcpp::observable<>::just<std::string>(std::string("event!")); return c; }).as_dynamic(); return b; } rxcpp::observable<std::string> FuncClass::disscconnect() { auto v = rxcpp::observable<>::interval(std::chrono::milliseconds(1000), rxcpp::observe_on_new_thread()) .map([=](long x) { return std::to_string(x); }) .take(2); return v; } void Conc::log(std::string txt) { std::cout << txt << std::endl; } rxcpp::observable<std::string> Conc::rxtest() { auto o = rxcpp::observable<>::just(10).as_dynamic(); rxcpp::observable<std::string> s = o.flat_map([=](int x) { return connect(); }) .as_dynamic() .flat_map([=](std::string c) { std::cout << "==>" << c << std::endl; log("log1"); return disscconnect(); }) .as_dynamic() .flat_map([=](std::string d) { log("log2"); log(d); this->hoge.hello(); return rxcpp::observable<>::just(d); }) .as_dynamic(); return s; }
操作を遅らせたりして動作を確認していた。
void rxtest2() { std::shared_ptr<Conc> conc = std::shared_ptr<Conc>::make_shared(); rxcpp::observable<std::string> x = conc->rxtest(); auto l = x.subscribe([=](auto r) { std::cout << "** get event **" << std::endl; std::cout << r << std::endl; }); conc.reset(); std::async(std::launch::async, [l]() { usleep(5 * 1000 * 1000); std::cout << "** unsubscribe **" << std::endl; l.unsubscribe(); usleep(5 * 1000 * 1000); std::cout << "** end **" << std::endl; }); }
色々やっているうちにコードが無駄に複雑化したがオブジェクトのデストラクタのタイミング等が少し理解できた。
分割コンパイル
hojo.hpp
int hello();
hojo.cpp
#include "hojo.hpp" int hello() { return 1000; }
hello.cpp
#include <iostream> #include "hojo.hpp" using namespace std; int main(){ cout << "Hello world." << endl; int x = hello(); cout << x << endl; return 0; }
というファイルをコンパイルしたいとする。 次のようなMakefileを作る。
objs = hello.o hojo.o
CC = clang++
hello: $(objs)
$(CC) -o hello $(objs)
hello.o:hello.cpp
$(CC) -c -o hello.o hello.cpp
hojo.o:hojo.cpp
$(CC) -c -o hojo.o hojo.cpp
clean:
rm -f $(objs)
これでmakeすればビルドできる。
CMakeで同様の事をする場合
CMakeLists.txt
cmake_minimum_required(VERSION 2.8) project(hello) add_executable(hello hello.cpp hojo.cpp)
を作り、
mkdir build cd build cmake .. make
でビルドできる。
そのご 他のフォルダをインクルードした
message("hoge")
cmake_minimum_required(VERSION 3.1)
enable_language(CXX)
set(CMAKE_CXX_STANDARD 14)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)
project(hello)
include_directories(/Users/hoge/RxCpp-4.0.0/Rx/v2/src)
# set(CMAKE_MODULE_PATH "usr/local/rxcpp" ${CMAKE_MODULE_PATH})
message("INCLUDE_DIRECTORIES ${INCLUDE_DIRECTORIES}")
message("CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH}")
# find_package(rxcpp)
add_executable(hello hello.cpp hojo.cpp)
