Characters

Type Char​

type Char = Prim.Types.Char

Characters represented as Unicode code points.

Value toNat32​

let toNat32 : (c : Char) -> Nat32

Convert character c to a word containing its Unicode scalar value.

Value fromNat32​

let fromNat32 : (w : Nat32) -> Char

Convert w to a character. Traps if w is not a valid Unicode scalar value. Value w is valid if, and only if, w < 0xD800 or (0xE000 <= w and w <= 0x10FFFF).

Value toText​

let toText : (c : Char) -> Text

Convert character c to single character text.

Function isDigit​

func isDigit(c : Char) : Bool

Returns true when c is a decimal digit between 0 and 9, otherwise false.

Value isWhitespace​

let isWhitespace : (c : Char) -> Bool

Returns the Unicode White_Space property of c.

Value isLowercase​

let isLowercase : (c : Char) -> Bool

Returns the Unicode Lowercase property of c.

Value isUppercase​

let isUppercase : (c : Char) -> Bool

Returns the Unicode Uppercase property of c.

Value isAlphabetic​

let isAlphabetic : (c : Char) -> Bool

Returns the Unicode Alphabetic property of c.

Function equal​

func equal(x : Char, y : Char) : Bool

Returns x == y.

Function notEqual​

func notEqual(x : Char, y : Char) : Bool

Returns x != y.

Function less​

func less(x : Char, y : Char) : Bool

Returns x < y.

Function lessOrEqual​

func lessOrEqual(x : Char, y : Char) : Bool

Returns x <= y.

Function greater​

func greater(x : Char, y : Char) : Bool

Returns x > y.

Function greaterOrEqual​

func greaterOrEqual(x : Char, y : Char) : Bool

Returns x >= y.

Function compare​

func compare(x : Char, y : Char) : {#less; #equal; #greater}

Returns the order of x and y.
