在 Dev-C++ 运行结果中显示占用内存大小 & 将 Windows Terminal 作为 Dev-C++ 的默认终端

前言

众所周知,Dev-C++ 是一款过时的 IDE,也是一款在 OI 选手中使用最多的 IDE。由于种种原因,短时间内无法抛弃它(NOIP/CSP 用的是它、像它一样即开即用的轻量 IDE 几乎没有、CP-Editor 还等待进一步的完善 、机房渣机连 VSCode 都带不动)。

(Dev 项目似乎被接手了,有了 6.0 版,但 BUG 一堆)

熟悉了 VSC 的内置终端、Windows Terminal 优美的字体渲染和 Fluent Design,再来看默认的 CMD 就觉得十分丑陋,于是就有了这篇文章,让 Dev-C++ 执行编译的程序时套一层 Windows Terminal 的壳,顺便给结果加上内存大小显示。

这篇文章十分水,就当是水文章了。

增加内存显示

Dev-C++ 调用其目录下一个名为 ConsolePauser.exe 的程序来套壳执行编译好的程序,顺便还可以输出一下运行时间。因为它是开源[1]的,所以直接在 ConsolePauser 的源代码[2]基础上改更快。直接加上内存统计的代码即可。注意编译参数要带上 -lpsapi

ConsolePauserPlus.cpp

// Execute & Pause
// Runs a program, then keeps the console window open after it finishes

#include <string>
using std::string;
#include <stdio.h>
#include <windows.h>
#include <Psapi.h>

#define MAX_COMMAND_LENGTH 32768
#define MAX_ERROR_LENGTH 2048

LONGLONG GetClockTick() {
	LARGE_INTEGER dummy;
	QueryPerformanceCounter(&dummy);
	return dummy.QuadPart;
}

LONGLONG GetClockFrequency() {
	LARGE_INTEGER dummy;
	QueryPerformanceFrequency(&dummy);
	return dummy.QuadPart;
}

void PauseExit(int exitcode) {
	system("pause");
	exit(exitcode);
}

string GetErrorMessage() {
	string result(MAX_ERROR_LENGTH,0);

	FormatMessage(
		FORMAT_MESSAGE_FROM_SYSTEM|FORMAT_MESSAGE_IGNORE_INSERTS,
		NULL,GetLastError(),MAKELANGID(LANG_NEUTRAL,SUBLANG_DEFAULT),&result[0],result.size(),NULL);

	// Clear newlines at end of string
	for(int i = result.length()-1;i >= 0;i--) {
		if(isspace(result[i])) {
			result[i] = 0;
		} else {
			break;
		}
	}
	return result;
}

string GetCommand(int argc,char** argv) {
	string result;
	for(int i = 1;i < argc;i++) {
		// Quote the arguments in case they contain spaces
		// Could use additional quoting code around the argument
		if(string(argv[i]).find(" ")!=string::npos) {
			result += string("\"") + string(argv[i]) + string("\"");
		} else {
			result += string(argv[i]);
		}

		// Add a space except for the last argument
		if(i != (argc-1)) {
			result += string(" ");
		}
	}

	if(result.length() > MAX_COMMAND_LENGTH) {
		printf("\n--------------------------------");
		printf("\nError: Length of command line string is over %d characters\n",MAX_COMMAND_LENGTH);
		PauseExit(EXIT_FAILURE);
	}

	return result;
}

double usedMemory;
int usedMemoryUnit = 0;
char usedMemoryUnitsName[5][5] = {"B", "KB", "MB", "GB", "TB"};

DWORD ExecuteCommand(string& command) {
	STARTUPINFO si;
	PROCESS_INFORMATION pi;
	memset(&si,0,sizeof(si));
	si.cb = sizeof(si);
	memset(&pi,0,sizeof(pi));

	if(!CreateProcess(NULL, (LPSTR)command.c_str(), NULL, NULL, false, 0, NULL, NULL, &si, &pi)) {
		printf("\n--------------------------------");
		printf("\nFailed to execute \"%s\":",command.c_str());
		printf("\nError %lu: %s\n",GetLastError(),GetErrorMessage().c_str());
		PauseExit(EXIT_FAILURE);
	}
	WaitForSingleObject(pi.hProcess, INFINITE); // Wait for it to finish

	PROCESS_MEMORY_COUNTERS pmc;
    GetProcessMemoryInfo(pi.hProcess, &pmc, sizeof(pmc));
    usedMemory = pmc.PeakPagefileUsage;
    while (usedMemory >= 1024){
    	usedMemory /= 1024.0;
    	usedMemoryUnit++;
	}

	DWORD result = 0;
	GetExitCodeProcess(pi.hProcess, &result);
	return result;
}

int main(int argc, char** argv) {

	// First make sure we aren't going to read nonexistent arrays
	if(argc < 2) {
		printf("\n--------------------------------");
		printf("\nUsage: ConsolePauser.exe <filename> <parameters>\n");
		PauseExit(EXIT_SUCCESS);
	}

	// Make us look like the paused program
	SetConsoleTitle(argv[1]);

	// Then build the to-run application command
	string command = GetCommand(argc,argv);

	// Save starting timestamp
	LONGLONG starttime = GetClockTick();

	// Then execute said command
	DWORD returnvalue = ExecuteCommand(command);

	// Get ending timestamp
	LONGLONG endtime = GetClockTick();
	double seconds = (endtime - starttime) / (double)GetClockFrequency();

	// Done? Print return value of executed program
	printf("\n--------------------------------");
	printf("\nProcess exited with return value %lu , Time: %.4g s , Memory: %.2lf %s\n",returnvalue,seconds,usedMemory,usedMemoryUnitsName[usedMemoryUnit]);
	PauseExit(EXIT_SUCCESS);
}

在 Windows Terminal 中运行

只要在原来的命令行前面调用一下 wt 即可。编译时加入 -mwindows 参数来隐藏一闪而过的 Console。

ConsolePauser.cpp

#include <string>
using std::string;
#include <stdio.h>
#include <windows.h>
#define MAX_COMMAND_LENGTH 32768
#define MAX_ERROR_LENGTH 2048
string GetCommand(int argc,char** argv) {
	string result;
	for(int i = 1;i < argc;i++) {
		if(string(argv[i]).find(" ")!=string::npos) {
			result += string("\"") + string(argv[i]) + string("\"");
		} else {
			result += string(argv[i]);
		}
		if(i != (argc-1)) {
			result += string(" ");
		}
	}
	if(result.length() > MAX_COMMAND_LENGTH) {
		printf("\n--------------------------------");
		printf("\nError: Length of command line string is over %d characters\n",MAX_COMMAND_LENGTH);
	}
	return result;
}
DWORD ExecuteCommand(string& command) {
	STARTUPINFO si;
	PROCESS_INFORMATION pi;
	memset(&si,0,sizeof(si));
	si.cb = sizeof(si);
	memset(&pi,0,sizeof(pi));
	if(!CreateProcess(NULL, (LPSTR)command.c_str(), NULL, NULL, false, 0, NULL, NULL, &si, &pi)) {
		exit(0); 
	}
	WaitForSingleObject(pi.hProcess, INFINITE);
	DWORD result = 0;
	GetExitCodeProcess(pi.hProcess, &result);
	return result;
}
int main(int argc, char** argv) {
	if(argc < 2) {
		printf("\n--------------------------------");
		printf("\nUsage: ConsolePauser.exe <filename> <parameters>\n");
	}
	string command = GetCommand(argc,argv);
	command = "wt ConsolePauserPlus.exe " + command;
	ExecuteCommand(command);
}

替换

编译以上两个程序,替换到 Dev-C++ 目录下,然后将 Dev 的目录加入环境变量,当下一次按下 F10 的时候,看到的就是漂亮的 Fluent Design 界面了。

    要不试试codeblocks?
    感觉也比较轻量

    小熊猫devCpp貌似bug少一些,到6.2版本了好像,可以看看
