[Boost-users] [Program option] Parsing string to vector<string>

18 Feb 2007

      Dear all

I have question. to the type of object stored in variables_map. In the
example multiple_sources.cpp

There is line:
    config.add_options()
//...
      ("include-path,I", 
         po::value< vector<string> >()->composing(), 
         "include path")
      ;

But independently of the case all time result vector has size = 1, so in
fact above is equivalent:

    config.add_options()
//...
      ("include-path,I", 
         po::value< string >()->composing(), 
         "include path")
      ;

And still there is some parsing job to do.

How can it be improved?

I have tested this example using config file like below:

#
# Comment out this line to use hard-coded default value of 10
# 
optimization = 1
include-path = /opt /usr /home/

Regards.
