Basic .txt ini reader.

[wildrj]

Well i needed a basic ini reader for my project so i decided to make one :/. It supports basic ini formatting..

Code: Select all

[Section]
Id=value
;comment here just make sure it doesn't have a equal sign

The only thing diffrent is the constructor it takes a file and a "badge"
the badge is just something you put at the top of your ini file to make sure its the right one.

So here ya guys go

Code: Select all

#include <iostream>
#include <fstream>
#include <string>
#include <stdlib.h> 

class cIniReader{

	public:
		cIniReader(std::string file,std::string badge);
		~cIniReader();

		int getInt(std::string id);
		std::string getStr(std::string id);
		bool valueFind(std::string str, std::string id);

	private:
		
		bool checkBadge();

		std::string iniFile;
		std::string iniBadge;
		std::string iniValueTemp;
};

Code: Select all

#include "CIniReader.h"

cIniReader::cIniReader(std::string file, std::string badge)
{

	iniFile = file;
	iniBadge = badge;
	std::string iniValueTemp = "";
}

cIniReader::~cIniReader()
{

}

int cIniReader::getInt(std::string id)
{
	std::string temp;
	bool checked = false;

	if(checkBadge())
	{
		std::ifstream myfile(iniFile.c_str());
		while(checked != true && myfile.eof() == false)
		{	
			std::getline(myfile,temp);
			if(valueFind(temp,id) != false)
			{
				checked = true;
			}
		}

		if(checked == true)
		{
			return atoi(iniValueTemp.c_str());
		}
		else
		{
			return 0;
		}

	}
	else
	{
		return 0;
	}

}


std::string cIniReader::getStr(std::string id)
{
	std::string temp = "";
	bool checked = false;

	if(checkBadge())
	{
		std::ifstream myfile(iniFile.c_str());
		while(checked != true && myfile.eof() == false)
		{	
			std::getline(myfile,temp);
			if(valueFind(temp,id) != false)
			{
				checked = true;
			}
		}

		if(checked == true)
		{
			return iniValueTemp;
		}
		else
		{
			return "";
		}

	}
	else
	{
		return "";
	}

}

bool cIniReader::valueFind(std::string str,std::string id)
{
	std::string temp = "";
	size_t found;

	found = str.find("=");

	if(found != std::string::npos)
	{
		temp = str.substr(0,found);
		if(temp == id)
		{
			iniValueTemp = str.substr(found + 1);
			return true;
		}

	}
	else
	{
		return false;
	}

}

bool cIniReader::checkBadge()
{
	std::ifstream myfile(iniFile.c_str());
	std::string badge;

	if(myfile.is_open())
	{
		std::getline(myfile,badge);
		myfile.close();
		if(badge == iniBadge)
		{
			return true;
		}
		else
		{
			return false;
		}
	}
	else
	{
		return false;
	}
}

And heres how to use it

Code: Select all

#include <iostream>
#include <string>
#include "CIniReader.h"
int main(){
	int test;
	std::string test2;
	cIniReader read("test.ini", "[BadgeHere]");
	test = read.getInt("Test");
	test2 = read.getStr("Test2");
	std::cout<<"Test =" << test <<std::endl;
	std::cout<<"Test2 =" << test2 <<std::endl;
	std::cin.get();
	return 0;
}

seems interesting that you didnt use the irrlicht file system methods (seeing as you are using irrlicht).

But its yet another snippet someone might find useful, thanks

[wildrj]

Re usable code .. So the reader can be used for something other then irrlicht related games

[hybrid]

Yeah, but now this code is not usable for e.g. zip file content.

Nice small class.
However is there a reason why you parse the whole file when you read a value?
You could store the content of the file in your object so you don't have to read the file over and over again.
