| Summary : A powerful and easy-to-use command-line option parser
|
Description :
The \'options\' package lets library and application developers easily work with
command-line options.
The following example is a full program that can accept two options,
\'--message\' and \'--quiet\':
\' import Control.Applicative import Options
data MainOptions = MainOptions { optMessage :: String ,
optQuiet :: Bool }
instance \'Options\' MainOptions where defineOptions = pure MainOptions
< *> simpleOption \"message\" \"Hello world!\" \"A message to show the
user.\" < *> simpleOption \"quiet\" False \"Whether to be quiet.\"
main :: IO () main = runCommand $ \\opts args -> do if optQuiet opts
then return () else putStrLn (optMessage opts) \'
>$ ./hello >Hello world! >$ ./hello --message=\'ciao mondo\' >ciao mondo >$
./hello --quiet >$
In addition, this library will automatically create documentation options such
as \'--help\' and \'--help-all\':
>$ ./hello --help >Help Options: > -h, --help > Show option summary. >
--help-all > Show all help options. > >Application Options: > --message :: text
> A message to show the user. > default: \"Hello world!\" > --quiet :: bool >
Whether to be quiet. > default: false.
