String functions
pluralize :: Int -> String -> String Source #
pluralize count singular pluralizes the given singular word unless given
count is 1.
Examples:
>>>pluralize 0 "example""0 examples"
>>>pluralize 1 "example""1 example"
>>>pluralize 2 "example""2 examples"
lineBreaksAt :: Int -> String -> [String] Source #
ensure that lines are not longer than given n, insert line breaks at word
boundaries
Working with paths
type Path = ([String], String) Source #
A Path represents the location of an example within the spec tree.
It consists of a list of group descriptions and a requirement description.
formatRequirement :: Path -> String Source #
Try to create a proper English sentence from a path by applying some heuristics.
filterPredicate :: String -> Path -> Bool Source #
A predicate that can be used to filter a spec tree.
Working with exception
safeTry :: IO a -> IO (Either SomeException a) Source #
safeTry evaluates given action and returns its result. If an exception
occurs, the exception is returned instead. Unlike try it is agnostic to
asynchronous exceptions.
formatException :: SomeException -> String Source #
The function formatException converts an exception to a string.
This is different from show. The type of the exception is included, e.g.:
>>>formatException (toException DivideByZero)"ArithException (divide by zero)"
For IOExceptions the IOErrorType is included, as well.
