System.Extended.MathPauses.PrintMessage

Maintainer : [e-mail]

Creates the time intervals for CLI changing messages on the screen.

IO functions

printUpdatedMsg :: String -> [String] -> Int -> IO ()

Function printUpdatedMsg prints a sequence of the first String concatenated with the appropriate element of the second [String] argument through special time interval specified by the Int argument after the pause in the Int microseconds (1/10^6 second) (approximately, depending on the GHC generated code performance). This looks like continually updated string on the screen of the terminal. All String arguments must not contain the special symbols '\n' and '\r' and vertical spaces. Please, check by yourself that the Int argument does not exceed the maxBound :: Int. Please, note that the String and Int are taken strictly, not lazily as is by default in Haskell.

printUpdatedMsg2 :: String -> [String] -> [Int] -> IO ()

Function printUpdatedMsg2 works the same as the function printUpdatedMsg with the difference that time intervals are specified by the list of Ints. The length of the lists must be equal, otherwise the function will truncate them to the less of the both ones length. Please, check by yourself that every Int argument does not exceed the maxBound :: Int. Please, note that the String and Int are taken strictly, not lazily as is by default in Haskell.

endZQuotInteger :: Double -> Integer -> IO (Double, Integer)

Function endZQuotInteger splits a Double argument to a less by absolute value Double specified by the Integer argument with some regularization for the uncommon values. The function is strict by its arguments.

Pure functions

No 'golden ratio' inside

endZQuot :: Double -> (Double, Integer)

Function endZQuot returns a tuple of numbers -- a fractional part and a whole part of the number. The function is strict by its arguments. Inspired by: https://mail.haskell.org/pipermail/beginners/2009-November/002814.html

The 'golden ratio' inside

phi0 :: Double

Famous mathematical constant of the 1/('golden ratio').

timeIntervalsPHi0 :: Double -> [Int]

Function timeIntervalsPHi0 produces a list of Ints of the time interval values for the threadDelay function. These time interval points can create for some users an impression of the smooth convergence to the end of the time intervals. The function is strict by its arguments.

timeIntervalsPHi0s :: Double -> [Double]

The same as timeIntervalsPHi0 function, but the result is in seconds. The function is strict by its arguments.

Differences functions

deltaTimePHi0 :: Double -> [Int]

Function deltaTimePHi0 returns a list of Ints of the differences between the neighbour values in the list produced by the timeIntervalsPHi0 function. The function is strict by its arguments.

deltaTimePHi0s :: Double -> [Double]

The same as deltaTimePHi0 function, but the result is in seconds. The function is strict by its arguments.
