strWidth :: String -> Int

Alias for realLength.
strWidthAnsi :: String -> Int

hledger Hledger.Cli.Script
Raises an error with a printf-specific prefix on the message string.
usageError :: String -> a
hledger Hledger.Cli.Script
A version of errorWithoutStackTrace that adds a usage hint.
error' :: String -> a
hledger Hledger.Cli.Script
Simpler alias for errorWithoutStackTrace

Synonym for error. Used for instances where the program has decided to exit because of invalid user input, or the user pressed quit etc. This function allows error to be reserved for programmer errors.
