(C++) Class for reading Windows-INI-like files

Sylence · Post by **Sylence** » Sat Mar 03, 2007 10:06 pm

Hello everyone!
I'm reading this forum for a long time now and it was always very useful for me. Now I reached the point where I want to give something back to the great community so I decided to post this class here.

I know that Irrlicht has its own XML parser, but I dont like XML...

I'm using this class in almost every project when I need to have a configuration file and I find it always very useful.

UPDATE:
The code is now avaible under http://btbsoft.org it's now a bit faster and was redesigned.

Thanks

I don't know if I got you right, but the whole file is loaded into memory and it is just parsed one time (in the load() method)

aside from more simplistic manual editing why would someone prefer this to xml?

considering you have all those extra libraries and such just to have this.

I fail to see the point could you explain it please?

yeah why does everyone diss XML?

this is nice too though, good work

(I like how you make irrlicht specific values like scolor and vector3df)

I still fail to see INI's advantage over XML considering you need to add what I thought were bloated include directory's

besides the fact that those includes are useful for other stuff.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

I was referring to these.

but then again xml probably uses them also.

but you're not going to see ANY advantage on that level unless you remove irrXML from Irrlicht.

um guys, what about changing stringc type to int? simple typecasting dont work

Sylence · Post by **Sylence** » Sun Mar 18, 2007 6:28 pm

I realized that there's a bug when loading a file with comments in it...

inside the load()-method you have change

Code: Select all

if(strncmp(buffer,"##",2) == 0)
	continue;

to

Code: Select all

if(strncmp(buffer,"##",2) == 0)
{
	buffer = strtok(content,"\n");
	continue;
}

I have also updated the complete code in my previous post...
I should test my classes before showing them to anybody

@Sylence, Any updates on the loading of key-codes in your class?

It is nothing special.

You just have to include the header inside the CfgFile.cpp and remove the comments
