You should be able to use the arg
method in your binfile, e.g.
main do |my,args|
# ... whatever
end
arg :first_arg, "The first arg"
arg :second_arg, :optional, "the second arg"
go!
Methadone should bomb out if the first arg is omitted (and, handily, you can code your main
block relying on it being non-nil
)
Another option is to use the method help_now!
to do this: http://davetron5000.github.com/methadone/rdoc/classes/Methadone/ExitNow.html#method-i-help_now-21
Basically, you can check for no arguments:
main do |my,args|
help_now!("you must supply an argument") if my.nil?
end
This will raise an exception that Methadone interprets as "something went wrong and the user needs to see the command line help".
Hi
After perusing the source for a while I've decided to call this an issue. When a user calls my app with no arguments, I'd like my app to behave as though it had been called with --help. I'm not sure how to accomplish this within the framework you've provided.
Thanks,
