Running a parser
Arguments
| :: CmdLnInterface a | Command line spec |
| -> (a -> IO ()) | Process to run if the parsing success |
| -> IO () |
Runs a command line application with the user provided arguments. If the parsing succeeds, run the application. Print the returned message otherwise
Arguments
| :: Args | Arguments to parse |
| -> CmdLnInterface a | Command line spec |
| -> ParseResult a |
Parse the arguments with the parser provided to the function.
Arguments
| :: NiceArgs | Arguments to parse |
| -> CmdLnInterface a | Command line spec |
| -> ParseResult a |
Parse the arguments with the parser provided to the function.
Building a parser
mkApp :: ParserSpec a -> IO (CmdLnInterface a)Source
Build an application with no version/description and with a name equal to the file name.
mkDefaultApp :: ParserSpec a -> String -> CmdLnInterface aSource
Build an application with no version/description and with a name equal to the provided String.
defaultSpecialFlags :: [SpecialFlag a]Source
default version and help special actions
setAppDescr :: CmdLnInterface a -> String -> CmdLnInterface aSource
Set the description of an interface
setAppEpilog :: CmdLnInterface a -> String -> CmdLnInterface aSource
Set the bottom text of an interface
setAppName :: CmdLnInterface a -> String -> CmdLnInterface aSource
Set the name of an interface
