Command-line argument processing

This library provides an easy way to define command line parsers. Most users will want to use the “System.Console.CmdArgs.Implicit” module, whose documentation contains an example.

  • System.Console.CmdArgs.Explicit provides a way to write command line parsers for both single mode programs most programs and multiple mode programs e.g. darcs or cabal. Parsers are defined by constructing a data structure.

  • System.Console.CmdArgs.Implicit provides a way to concisely define command line parsers, up to three times shorter than getopt. These parsers are translated into the Explicit data type.

  • System.Console.CmdArgs.GetOpt provides a wrapper allowing compatiblity with existing getopt parsers, mapping to the Explicit data type.
