C ++ - parameter issue

Question

I am looking for a simple and efficient container of parameters that will act as a representation of an in-memory-xml file (or ini-file, as another example).

I mean, basically, it can store sections and parameter sets for each section, have simple accessors like GetValue("ParameterName") and a simple return value.

It would be great if it were serializable.

I wrote something similar yesterday and, well, it fits my needs, but maybe there is something more convenient and flexible available?

Maybe some kind of parameter map in boost ?

thanks

Answer 1

Take a look at boost :: program_options . It does what you want and much more: parsing INI files, parsing environment variables, parsing options, and expanding the command line.

Answer 2

Did you consider std :: map <> ?

Answer 3

It is wrong if it is full or not, but the Message Class in MUSCLE does all of the above. You can use it to serialize any data (structured or not) or use it as a container in memory for parsed .ini style configuration files through ParseFile () / UnparseFile () .

Answer 4

You can use Boost.PropertyTree .

It reads and writes xml and ini files.

Saves the parameters as a tree, and you can use dot notation to access the values:

 std::string value = pt.get<std::string>("debug.filename"); 

You can also insert new values ​​using:

 pt.put("debug.filename", fileName);
