Mar 27, 2014 · It says that the complete code examples can be found at "BOOST_ROOT/libs/program_options/example" directory. I could not figure out where is this. Can anyone help me finding the examples?

Aug 19, 2015 · else if(j.size() >= 1 && j[0] == x1[0]) { cout << "if - x1 = You have selected the option " << j; } if you will make sure that first character of your menu strings are identifiers to choose this menu. Also, the last else with no condition is where you …

Feb 1, 2016 · Here's an example that prints out each input multi-token option on a separate line: // Define a multi-token option. po::options_description desc("Allowed options"); desc.add_options() ("list", po::value<std::vector<std::string>>()->multitoken(), "multiple values"); // Just parse the options without storing them in a map.

This illustrates an important example, the way program_options works, is that a parser will not override a value that has previously been set by another parser. Thus the env parser doesn't override the command line parser. (We will see this again in config files.)

options(desc).positional(p).run(), vm); po::notify(vm); if (vm.count("help")) { cout << "Usage: options_description [options]\n"; cout << desc; return 0; } if (vm.count("include-path")) { cout << "Include paths are: " << vm["include-path"].as< vector<string> >() << "\n"; } if (vm.count("input-file")) { cout << "Input files are: " << vm["input ...

In this section, we'll take a look at the most common usage scenarios of the program_options library, starting with the simplest one. The examples show only the interesting code parts, but the complete programs can be found in the "BOOST_ROOT/libs/program_options/example" directory.

We could use boost to parse program options and positional options. In the below program ( example.cpp ) we pass program options some of which are positional options to the program. Compilation : Program : example.cpp.

Boost.Program_options is a C++ library designed to ease the handling of command-line options in programs. It offers a straightforward way to parse and manage arguments provided by users when running the program.
