A commandline parsing library, based on getopt. Comes with a
powerful attribute system. Supports complex interfaces with many
options and commands, with option & command grouping, with simple
and convenient API. Even though quite powerful, it strives to keep
simple things simple. The library uses
In comparison to the other commandline handling libraries:
Compared to cmdargs, cmdlib has a pure attribute system and is based on GetOpt for help formatting & argument parsing. Cmdlib may also be more extendable due to typeclass design, and can use user-supplied types for option arguments.
Cmdargs >= 0.4 can optionally use a pure attribute system, although this is clearly an add-on and the API is a second-class citizen in relation to the impure version.
GetOpt and parseargs both require explicit flag representation, so they live a level below cmdlib. GetOpt is in fact used as a backend by cmdlib.
