Pass filenames without flags/options

[chrysante]

This will probably be trivial to answer, but I just can't figure it out. How can I parse filename or directory arguments without them being 'options'? Basically I would like to invoke my executable like this:

./my_app -x -y --some-other-option input-a.txt input-b.txt

Instead of this:

./my_app -x -y --some-other-option --file input-a.txt --file input-b.txt

I guess it has something to do with positional arguments, but I can't figure out how to use them. Any pointers would be appreciated.

Thanks!

std::vector<std::string> files
app.add_option("files",files,"file to use")->check(CLI::ExistingFile)
/// all other options

this adds a positional option and puts all positional arguments in a vector

[phlptp]

adding an option with no -- in front of the strings creates the positional arguments if you wanted to both it would be

app.add_option("--file,files",files,"file to use")->check(CLI::ExistingFile)

the the positional works and you can specify with an option as well

Works like a charm, thank you very much! Also for the great library :)
