Double dash for argument prefix #5

Closed dmarlow closed 2 years ago

dmarlow commented 4 years ago

I'm specifying the argument prefix like this: var parser = new CommandLineParser(typeof(Options), new[] { "-", "--" });

But, when I attempt to use -- like this: myapp.exe --flag

I get the following error: Unknown argument name '-flag'.

Looks like if I switch the order of the prefixes, it works. 🤷‍♂

This is working as intended. The prefixes are checked in the order they are provided, so when - matches, -- is never considered. As you indicated, the solution is to specify the longer prefixes first.
