Redirect default -h help to a custom logger instead of the terminal

[eugenesvk]

If I have a "gui" Windows app that doesn't get any console attached at startup, but does get arguments from the .lnk file, I can parse those arguments as though it's a regular cli/terminal launch

However, since there is no console, all output, for example, from -h, is swallowed.

But I do have a custom logger that logs to a different target than stdout (i.e., some SimpleLogger type redirecting to Windows outputdebugstring).

Is there a way to ask Clap to use this custom logger instead of the default stdout target?

Help is reported up as an error. You could use a try_ variant of a parser function so you can check the error, see if its use_stderr or if the ErrorKind is for help, and then print it a custom way.

Thanks, this should work, didn't think that a successful -h parsing would be treated as an error
