I'm searching for a way to write complex data configurations for my application.
I don't really like xml or json for that job for different reasons.
But I found a format that is kind of perfect for the job, it's implemented in boost property tree library and is referenced as "INFO" format( http://www.boost.org/doc/libs/1_46_1/doc/html/boost_propertytree/parsers.html#boost_propertytree.parsers.info_parser ).
The problem is I can't find a proper format description/reference because of the same named "info" file format for text info.
Can some one share a link to a proper documentation or at least more exaples?
Did you look at the Boost docs on this? I doubt there's a better reference. As noted in the doc:
It provides a simple, efficient format that can be used to serialize property trees that are otherwise only stored in memory. It can also be used for any other purpose, although the lack of widespread existing use may prove to be an impediment.
Generally I bemoan the overuse of XML but in this case, going that route (XML) is just as functional and a lot less controversial. You get third-party parsing, transform (XSLT) and editing tools that you won't have with INFO.
