The current Ini file reading util function is very handy, but it is unable to cope with sections that some people put in .Ini files. These are usually deliminated by [SECTION_NAME], but people have nasty habit of just making it up as they go along Smile

I have a requirement to read such a file and wondered whether the following minor change could be committed for me so that I don't have to duplicate code:

Util.cpp:

VectorMap<String, String> LoadIniFile(const char *filename) {
	FileIn in(filename);
	if(!in) return VectorMap<String, String>();
	return LoadIniStream(in);
}

VectorMap<String, String> LoadIniStream(Stream &in) {
	VectorMap<String, String> key;
	int c;
	if((c = in.Get()) < 0) return key;
	for(;;) {
		String k, v;
		for(;;) {
			if(IsAlNum(c) || c == '_')
				k.Cat(c);
			else
				break;
			if((c = in.Get()) < 0) return key;
		}
		for(;;) {
			if(c != '=' && c != ' ') break;
			if((c = in.Get()) < 0) return key;
		}
		for(;;) {
			if(c < ' ') break;
			v.Cat(c);
			if((c = in.Get()) < 0) break;
		}
		if(!k.IsEmpty())
			key.Add(k, v);
		if(k == "LINK") {
			in.Close();
			if(!in.Open(v) || (c = in.Get()) < 0) return key;
		}
		else
			for(;;) {
				if(IsAlNum(c) || c == '_') break;
				if((c = in.Get()) < 0) return key;
			}
	}
}

Util.h:

VectorMap<String, String> LoadIniFile(const char *filename);
VectorMap<String, String> LoadIniStream(Stream &in);

This means that I can just read .Ini file to correct section myself and then call LoadIniStream.

Cheers!
