INI Files

Hello,

I'm going to start working on a program that will save your preferences in a .ini form. I want to follow the INI file standards, but I have no clue how I would parse this in a c++ program.

Code:

---

(test.ini)
[header]
variablename=value
variablename2=anothervalue

---

If someone could help, I would very much appreciate it.

Thanks,

Matt

So the first line must contain the filename surrounded in (). Presumably you know the name of the filename you attempted to open, so you can check that it's right -- or you can ignore it if you don't care.

Then I guess you need to read in "[header]".

Then you read something=something else. You can use the three-parameter form of getline, using '=' for the delimiter. You had better know what all the possible things for the left side are; you then do a lot of if-else checks, or perhaps something more fancy if you have a lot of different left-hand sides; whatever the left side is, that tells you how to read the right-hand side.

Repeat until tired or out of data.

Actually, I dont need the (filename) thing, I don't know why I put that there :)

But as for the getline idea, it sounds like it'll work! Thanks for the idea!

There's plenty of free INI file parsers out there, such as this one: http://ndevilla.free.fr/iniparser/

I prefer not to reinvent the wheel unless I know I can make a better wheel.

Does it? I don't think I've seen many (or any?) INI files that do that.

I have no idea. I just went from the example quoted.
