Configuration file parser

**publikum** · 02-13-2005

How can I parse a simple configuration file (with less than 10 options) in Win32...?

Thanks for help in advance!

I would start by loading the file into memory.

Does the file have a new config variable on every new line? If so, you can just read the first characters, up to white space into a string as the variable name, with what follows as the value.

I'm assuming the file looks something like this:

Config.cfg
Variable1 = 0
Variable2 = somestring
Variable3 = true
Variable4 = 34

That's how I'd get started. I'll leave variable types and such up to you

There's a Config library, not very refined yet, in the Boost libraries, which can read options from config files.

CornedBee :You mean Program_options?? I really can't find the correct library...

Yep, Program Options it is. It can read files too.

Thanks, but the next problem seems to be linker, which doesn't want to link compiled program (even if I add libboost.a to project and copy boost.dll to project's bin dir...)...My IDE is Dev-C++....
