ListFormat

format

RESCRIPT

let format: (t, array<string>) => string

format(formatter, items) returns the formatted list string.

Examples

RESCRIPT
let formatter = Intl.ListFormat.make(~locales=["en"])
formatter->Intl.ListFormat.format(["a", "b"]) == "a and b"

formatToParts

RESCRIPT

let formatToParts: (t, array<string>) => array<listPart>

formatToParts(formatter, items) returns the list as an array of parts describing how it would be rendered.

See Intl.ListFormat.prototype.formatToParts on MDN.

Examples

RESCRIPT
let formatter = Intl.ListFormat.make(~locales=["en"])
formatter->Intl.ListFormat.formatToParts(["a", "b"])->Array.length > 0

ignore

let ignore: t => unit

ignore(listFormat) ignores the provided listFormat 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.

  \"type": listPartComponentType,
  value: string,
}

make

RESCRIPT

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

Creates a new Intl.ListFormat instance for formatting lists.

See Intl.ListFormat on MDN.

type options = {
  localeMatcher?: Intl_Common.localeMatcher,
  \"type"?: listType,
  style?: style,
}

resolvedOptions

RESCRIPT

type resolvedOptions = {
