func (AdventYears) FirstYearDir

func (years AdventYears) FirstYearDir(cwd string) (Year, string, error)

FirstYearDir tries to find and return a path of the first aoc year where the year exists as a dir in the given cwd.

func (AdventYears) Len

func (years AdventYears) Len() int

func (AdventYears) Less

func (years AdventYears) Less(i, j int) bool

func (AdventYears) Swap

func (years AdventYears) Swap(i, j int)

type Date

type Date struct {
	Year
	Day
}

Date represents an Advent of Code date

type DatePart

type DatePart struct {
	Date
	Part
}

)

First and last Day constants.

type Year

type Year int

Year represents an Advent of Code year.

func LastYear
