%global pkg_name optparse-applicative
%global common_summary Utilities and combinators for parsing command line options
%global common_description Here is a simple example of an applicative option parser:\
\
@\
data Sample = Sample\
  { hello :: String\
  , quiet :: Bool }\
\
sample :: Parser Sample\
sample = Sample\
  \<$\> strOption\
  ( long \"hello\"\
  & metavar \"TARGET\"\
  & help \"Target for the greeting\" )\
  \<*\> switch\
  ( long \"quiet\"\
  & help \"Whether to be quiet\" )\
@\
\
The parser is built using applicative style starting from a set of basic\
combinators. 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.
