Description

AUTHOR: Dr. Alistair Ward
DESCRIPTION

Defines the days of the week.
This is required to define the day of a booking in the timetable.
Day/Time modules may already exist in the Haskell-platform's standard library, but since no account of; time-zones, locales, or leap-years, is required, they're undoubtedly over-engineered for the requirement.

Synopsis

type Weekend = Set Day
data Day
tag :: String
nDaysPerWeek :: NDays
range :: [Day]
getYesterday :: Day -> Day
getTomorrow :: Day -> Day
getAdjacentDays :: Day -> (Day, Day)

Constants

tag :: String Source #

Used to qualify SQL & XML.

nDaysPerWeek :: NDays Source #

The constant number of days in a week.

range :: [Day] Source #

The constant complete range of values.

Functions

getYesterday :: Day -> Day Source #

Like pred, but treats the enumerable type as a circular list.

getTomorrow :: Day -> Day Source #

Like succ, but treats the enumerable type as a circular list.

getAdjacentDays :: Day -> (Day, Day) Source #

Returns yesterday & tomorrow.
