get full original command line (full argv[]) within a command function

[andrewhlin]

Is there currently an easy way to pull out the full original command line string that was used to invoke the program (essentially what argv was) from within a Command/subparser with the current API? I use the commands interface, and have a separate function that is invoked for subcommands. Within a subcommand, I want to be able to get the full command line to be able to print it out to a log file that gets created based on the input args to the program. Is there a way to do this right now that I'm just missing?

You can capture argc and argv in lambda and pass them to your function:

Command command(..., [=](Subparser& p) { MyCommand(p, argc, argv); });

Or use std::bind:

Command command(..., std::bind(MyCommand, _1, argc, argv));

There is no other way to do it with current API.
