Documentation
readCommandFlags :: FilePath -> CommandUI flags -> IO flags Source #
Read command-line arguments, separated by null characters, from a file. Returns the default flags if the file does not exist.
writeCommandFlags :: Verbosity -> FilePath -> CommandUI flags -> flags -> IO () Source #
Write command-line flags to a file, separated by null characters. This
format is also suitable for the xargs -0 command. Using the null
character also avoids the problem of escaping newlines or spaces,
because unlike other whitespace characters, the null character is
not valid in command-line arguments.
