RelativeTimeFormat

Bindings to JavaScript's Intl.RelativeTimeFormat.

See MDN for API details.

format

RESCRIPT

let format: (t, int, timeUnit) => string

format(formatter, value, unit) returns the formatted string for value expressed in unit.

Examples

RESCRIPT
let formatter = Intl.RelativeTimeFormat.make(~locales=["en"])
formatter->Intl.RelativeTimeFormat.format(-1, #day)->String.length > 0

formatToParts

RESCRIPT

let formatToParts: (t, int, timeUnit) => array<relativeTimePart>

formatToParts(formatter, value, unit) returns an array describing how the output string is assembled.

See Intl.RelativeTimeFormat.prototype.formatToParts on MDN.

Examples

RESCRIPT
let formatter = Intl.RelativeTimeFormat.make(~locales=["en"])
formatter->Intl.RelativeTimeFormat.formatToParts(-1, #day)->Array.length > 0

ignore

RESCRIPT

let ignore: t => unit

ignore(relativeTimeFormat) ignores the provided relativeTimeFormat and returns unit.

This helper is useful when you want to discard a value (for example, the result of an operation with side effects) without having to store or process it further.

make

RESCRIPT

let make: (~locales: array<string>=?, ~options: options=?) => t

Creates a new Intl.RelativeTimeFormat instance for formatting relative time strings.

See Intl.RelativeTimeFormat on MDN.

Examples

RESCRIPT
let formatter = Intl.RelativeTimeFormat.make(~locales=["en-US"])
formatter->Intl.RelativeTimeFormat.format(1, #day)->String.length > 0

numeric

RESCRIPT

type numeric = [#always | #auto]

options

RESCRIPT

type options = {
  localeMatcher?: Intl_Common.localeMatcher,
  numeric?: numeric,
  style?: style,
}

relativeTimePart

RESCRIPT

type relativeTimePart = {
  \"type": relativeTimePartComponent,
  value: string,
  unit?: timeUnit,
}

relativeTimePartComponent

RESCRIPT

type relativeTimePartComponent = [#integer | #literal]

resolvedOptions

RESCRIPT

type resolvedOptions = {
  locale: string,
  numeric: numeric,
  style: style,
  numberingSystem: string,
}

resolvedOptions

RESCRIPT

let resolvedOptions: t => resolvedOptions

resolvedOptions(formatter) returns the locale and options currently in use.

See Intl.RelativeTimeFormat.prototype.resolvedOptions on MDN.

Examples

RESCRIPT
let formatter = Intl.RelativeTimeFormat.make(~locales=["en-US"])
Intl.RelativeTimeFormat.resolvedOptions(formatter).locale == "en-US"

style

RESCRIPT

type style = [#long | #narrow | #short]

supportedLocalesOf

RESCRIPT

let supportedLocalesOf: (
  array<string>,
  ~options: supportedLocalesOptions=?,
) => array<string>

supportedLocalesOf(locales, ~options) filters locales to those supported for relative time formatting.

See Intl.RelativeTimeFormat.supportedLocalesOf on MDN.

Examples

RESCRIPT
Intl.RelativeTimeFormat.supportedLocalesOf(["en-US", "klingon"]) == ["en-US"]

supportedLocalesOptions

RESCRIPT

type supportedLocalesOptions = {
  localeMatcher: Intl_Common.localeMatcher,
}

t

RESCRIPT

type t

timeUnit

RESCRIPT

type timeUnit = [
  | #day
  | #hour
  | #minute
  | #month
  | #quarter
  | #second
  | #week
  | #year
