Exit code 1 when running with --version

[nhedger]

While publishing a CLI on Homebrew, it was pointed out that the our CLI exits with code 1 when running with only --version.

I believe this behavior to be caused by this:

bpaf/src/info.rs

Line 285 in 8a948b1

return Err(ParseFailure::Stdout(buffer, detailed));

Is there a reason we don't return exit code 0 in such a case?

Thanks for your insights.

$ cargo asm --version
Version: 0.2.20
$ echo $?
0

It should produce 0 if application sets version number in some way. It can produce 1 if version is not set and parse fails.

You can specify a version like so: https://docs.rs/bpaf/0.9.5/bpaf/struct.OptionParser.html#method.version

Ah, I must have misunderstood! Your help is much appreciated. I'll try this.

Thanks for a nice lib.
