Re: [Boost-users] program_options - save configuration

Saving configuration in a human-readable text file would certainly be useful. It'd be nice to be able to write out a default parameter file containing all possible options, their default (=current?) values, and comments on each option (possibly including a list of permitted values). //Mikko Aljaz wrote:

Also if you have lets say 30 program options, would that be stupid to write all in command line?

It would be cool if I had GUI for user confguration, but its confusing if user wants to edit serialized config file by himself.

Hmmm - I'm wondering why you wouldn't use the seriailzation libary for this.

Here is the scenario:

take a program which uses program options. Add one more option e.g -i<file name>

On startup, check for -i switch. If switch isn't used, process options and store them in a class intance. On program shutdown, save class instance toa file using serialization. If swith IS used, just load class instance from file using serialization.

Seems to me that the two libraries complement each other in this case.

I wonder if there are any functions in boost program options libary to save them back to configuration file?

Maybe any example?

Thanks for help
