Functions

func DaysSince

func DaysSince(t time.Time) int

func DefaultMaxFloat

func DefaultMaxFloat(val, def, max float64) float64

func DefaultMaxInt

func DefaultMaxInt(val, def, max int) int

DefaultMaxInt returns the default if val is < 0, max if val is > max.

func DiffInDays

func DiffInDays(a, b time.Time) int

func Env

func Env(key string) string

func FToC

func FToC(f float64) float64

FToC converts fahrenheit to celsius

func FeetToMeters

func FeetToMeters(f float64) float64

FeetToMeters converts feet to meters

func FirstNonEmptyString

func FirstNonEmptyString(list ...string) string

func FirstNonZeroFloat

func FirstNonZeroFloat(list ...float64) float64

func FirstNonZeroInt

func FirstNonZeroInt(list ...int) int

func FirstPositiveFloat

func FirstPositiveFloat(list ...float64) float64

func FirstPositiveInt

func FirstPositiveInt(list ...int) int

func FuzzInt

func FuzzInt(input int, min, max int) int

FuzzInt adds or subtracts a certain percentage from the input. Ex: FuzzInt(100, 1, 100) will have an output range between 0 and 100 Ex: FuzzInt(100, 1, 10) will have an output range between 90 and 110, and will add/remove at least 1% Ex: FuzzInt(100, 8, 10) will have an output range between 90 and 110, and will add/remove at least 8%

func IsNil

func IsNil(i interface{}) (isNil bool)

Returns true if the given interface is nil.

func MaxFloat

func MaxFloat(a, b float64) float64

func MaxInt

func MaxInt(a, b int) int

MaxInt returns the larger of a or b

func MilesToKm

func MilesToKm(m float64) float64

MilesToKm converts miles to kilometers

func MinFloat

func MinFloat(a, b float64) float64

MinFloat returns the larger of a or b

func MinInt

func MinInt(a, b int) int

MaxInt returns the larger of a or b

func MinMaxFloat

func MinMaxFloat(val, min, max float64) float64

func MinMaxInt

func MinMaxInt(val, min, max int) int

MinMaxInt returns the min if val is < min, max if val is > max.

func ParseTime

func ParseTime(input string) (time.Time, error)

ParseTime attempts to extract a valid time.Time from an input string. We prefer RFC3999. Fallback should match MSSQL's CURRENT_TIMESTAMP.

func QuoteString

func QuoteString(s string) string

QuoteString adds quotes to a string.

func RatioPercent

func RatioPercent(a, b float64) float64

func RelativeTime

func RelativeTime(dur time.Duration) string

RelativeTime takes a time.Duration and returns the largest denomination relative time. eg. 1y for a duration over 400 days.

func Round

func Round(num float64) int

Round a floating point number to the nearest integer. -0.5 becomes -1, 0.5 becomes 1.

func ToFixed

func ToFixed(num float64, precision int) float64

ToFixed will set a fixed precision on a float.

func ZeroIfNilFloat

func ZeroIfNilFloat(in *float64) float64

func ZeroIfNilInt

func ZeroIfNilInt(in *int) int
