Print argv from a callback

[eolivi-fy]

Hi first of all, thank you for this good library!

I'd like to be able to print the command run:

> ./MyBinary --input file.txt --num 4 --log debug
Command run was: "./MyBinary --input file.txt --num 4 --log debug"
...

Of course I could simply call:

for (int i = 0; i < argc; i++)
   std::cout << argv[i] << " ";

// just before
app.parse(argc, argv);

But I feel there could be a way using a callback ?

This does it almost:

app.parse_complete_callback([&app](){
   std::cout << "Command run:\n" << app.config_to_str()) << std::endl;
}

Command run: log="debug" input="file.txt" num=4

maybe there is another way ?

I don't think a way was built to regenerate the command line directly inside CLI11.

Thanks, good enough then with app.config_to_str()
