In this example, 'hello' is defined as an 'option' with a 'String' argument, while 'quiet' is a boolean 'flag' (called 'switch'). A parser can be used like this: ' greet :: Sample -> IO () greet (Sample h False) = putStrLn $ "Hello, " ++ h greet _ = return () main :: IO () main = execParser opts >>= greet   where   opts = info (helper <*> sample)   ( fullDesc   <> progDesc "Print a greeting for TARGET"   <> header "hello - a test for optparse-applicative" ) ' The 'greet' function is the entry point of the program, while 'opts' is a complete description of the program, used when generating a help text. The 'helper' combinator takes any parser, and adds a 'help' option to it (which always fails). The 'hello' option in this example is mandatory (since it doesn't have a default value), so running the program without any argument will display a help text: >hello - a test for optparse-applicative > >Usage: hello --hello TARGET [--quiet] > Print a greeting for TARGET > >Available options: > -h,--help Show this help text > --hello TARGET Target for the greeting > --quiet Whether to be quiet containing a short usage summary, and a detailed list of options with descriptions. %package devel Summary: Haskell %{pkg_name} library development files Group: Development/Libraries/Other Requires: %{name} = %{version}-%{release} Requires: ghc-compiler = %{ghc_version} Requires(post): ghc-compiler = %{ghc_version} Requires(postun): ghc-compiler = %{ghc_version} %description devel This package provides the Haskell %{pkg_name} library development files. %prep %setup -q -n %{pkg_name}-%{version} %build %ghc_lib_build %install %ghc_lib_install %check %cabal_test %post devel %ghc_pkg_recache %postun devel %ghc_pkg_recache %files -f %{name}.files %defattr(-,root,root,-) %doc LICENSE %files devel -f %{name}-devel.files %defattr(-,root,root,-) %doc CHANGELOG.md README.md %changelog
