Better error message for missing value arguments
Fixes #363
The problem shows up when using an argument like this:
[Value(0, Min = 1, HelpText = "Path(s) to file(s)", Required = true)]
public IEnumerable<string> FilePaths { get; }
Calling the CLI without providing a value for this argument will currently result in the following error:
ERROR(S): A sequence value not bound to option name is defined with few items than required.
This patch changes the behaviour so that, iff a MetaName is provided in the ValueAttribute, the user of the CLI will receive a message along the lines of:
ERROR(S): Required option '$MetaName' is missing.
Any chance this could be merged? It looks like this project isn't very active. Is anyone maintaining this?
Ha, I had forgotten that this PR even existed. And the issue has been around for longer still :). @ericnewton76 - apologies for the ping, but is there anything I can do to help get this merged? I'm happy to tweak this as needed. Just let me know if there's anything you need from me.
