(CommandlineParser version 2.7.82)
When using a parser with the AutoHelp
setting set to false
i would expect the parser to not recognize the --help
option unless i have it explicitly declared as part of my options class. If i have no such declaration, i would expect the parser to treat --help
as an unknown option/error. Unfortunately, this is not the case. The parser still recognizes this option, even when AutoHelp
is set to false :(
The documentation comment for AutoHelp
(also shown by Intellisense) seems to support my expectations:
Gets or sets a value indicating whether implicit option or verb 'help' should be supported.
But that does not seem to be what that setting actually does...
Thus my question: What is the actual purpose and supposed effect of setting AutoHelp
for the parser to false
? And how would i make --help
not an option?
For example, if i use the unknown option --foo
, the HelpText.AutoBuild
method is able to generate a text containing:
ERROR(S):
Option 'foo' is unknown.
I want to get the same result when calling my program with the (unknown) option --help
:
ERROR(S):
Option 'help' is unknown.
Unfortunately, the parser or HelpText.AutoBuild
method seem to refuse to treat --help
as an unknown option (both parser settings AutoHelp
and IgnoreUnknownArguments
are set to false
)
:-(
