Description
Common code for parsing command line options based on getopt.
Synopsis
- type FunOptDescr cfg = OptDescr (Either (IO ()) (cfg -> cfg))
- mainWithOptions :: cfg -> [FunOptDescr cfg] -> String -> ([String] -> cfg -> Maybe (IO ())) -> String -> [String] -> IO ()
- commonOptions :: String -> String -> [FunOptDescr cfg] -> [FunOptDescr cfg]
Documentation
type FunOptDescr cfg = OptDescr (Either (IO ()) (cfg -> cfg)) Source #
A command line option that either purely updates a configuration, or performs an IO action (and stops).
mainWithOptions :: cfg -> [FunOptDescr cfg] -> String -> ([String] -> cfg -> Maybe (IO ())) -> String -> [String] -> IO () Source #
Generate a main action that parses the given command line options
(while always adding commonOptions).
commonOptions :: String -> String -> [FunOptDescr cfg] -> [FunOptDescr cfg] Source #
Common definitions for -v and -h, given the list of all other
options.
