It would be nice to describe a related set of required parameters as mutually exclusive, to get a 'radio button' type effect, where a user will choose exactly one of the options in the mutually exclusive group.
e.g., support these nicely
dbtool users create myuser
dbtool users delete myuser
dbtool users list
Ideally it would be a syntax for the command token like
cl.RegisterCommand(
createHandler,
"users|create <string-username>",
)
cl.RegisterCommand(
deleteHandler,
"users|delete <string-username>",
)
cl.RegisterCommand(
listHandler,
"users|list",
)
A global option handler gets a map with keys that have the dashes stripped out. These should be left in for uniformity sake.
Help filters are intended for programs with many commands. For programs with a single command that might be long, Help() is printing help for filters. Filters are useless when only a single command is possible.
The printing interface doesn't belong in cmdline and should be separated.
