Description
Now that #2102 in System.CommandLine 2.0.0-beta4.23172.1 made System.CommandLine.Help.HelpOption public, it would be handy if I could create an instance of HelpOption by using just new HelpOption("--help")
rather than new HelpOption("--help", aliases: null)
. That could be implemented in any of the following ways:
- new constructor:
public HelpOption(string name)
- optional parameter:
public HelpOption(string name, string[]? aliases = null)
- params:
public HelpOption(string name, params string[] aliases)
. That would be consistent with the Option<T> constructor.
I don't like using new HelpOption("--help", null)
with an unnamed null
argument because its purpose would not be immediately obvious to people reading the code. new HelpOption("--help", Array.Empty<string>())
is quite clear too but more verbose than a named argument.
(System.CommandLine.Help.VersionOption is not public yet.)
