The unicode library

Overview

The unicode library provides data and functions to test some properties of Unicode code points.

Modules

("unicode")

Types

Case = enum UPPER_CASE, LOWER_CASE, TITLE_CASE, MAX_CASE

An enum representing the various sorts of case recognized by the Unicode standard.

Functions

isControl(r rune) -> bool

isControl(r) reports whether r is a control character.

isDigit(r rune) -> bool

isDigit(r) reports whether r is a decimal digit.

isGraphic(r rune) -> bool

isGraphic(r) reports whether r is defined as a Graphic character by Unicode.

isIn(r rune, bounds ... pair)

isIn reports whether the rune lies within any of the bounds in bounds.

isLetter(r rune) -> bool

isLetter(r) reports whether r is a Unicode letter.

isLower(r rune) -> bool

isLower(r) reports whether r is a lower-case letter.

isMark(r rune) -> bool

isMark(r) reports whether r is a Unicode mark character.

isNumber(r rune) -> bool

isNumber(r) reports whether r is a Unicode number.

isPrint(r rune) -> bool

isPrint(r) reports whether r is defined as printable by Pipefish.

isPunct(r rune) -> bool

isPunct(r) reports whether r is a Unicode punctuation character.

simpleFold(r rune) -> rune

simpleFold(r) iterates over Unicode code points equivalent to r under Unicode simple case folding.

toCase(c Case, r rune) -> rune

Converts r to the given case.

toLower(r rune) -> rune

toLower(r) maps the Unicode letter r to lower case.
