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 "System.Console.GetOpt" as + its backend. + + 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. + </longdescription> +</pkgmetadata> |
