the built-in help flag is hard to customise

Open simonmichael opened this issue 10 years ago • 1 comments

I'd like to make -h a synonym for --help, and suppress -?. But "h" is automatically assigned to another flag (--hide-successes). If I add the "explicit" annotation to that one, cmdargs complains at runtime about a missing ? name. The example in helpArg's haddock (helpArg [explicit, name "h"]) complains about a repeated h name.

I just ran into the same issue in 2018. How actually do we make -h an alias for --help in cmdargs programs ?
