Пакет unicode
Обзор
Пакет unicode предоставляет данные и функции для проверки некоторых свойств кодовых точек Юникода.
Пример (Is)
Функции, начинающиеся с "Is", могут использоваться для проверки, к какой таблице диапазонов относится руна. Обратите внимание, что руны могут входить в более чем один диапазон.
Код:
// constant with mixed type runes
const mixed = "\b5Ὂg̀9! ℃ᾭG"
for _, c := range mixed {
fmt.Printf("For %q:\n", c)
if unicode.IsControl(c) {

} func In 1.2
func In(r rune, ranges ...*RangeTable) bool

func Is
func Is(rangeTab *RangeTable, r rune) bool
Is проверяет, принадлежит ли руна заданной таблице диапазонов.
func IsControl
func IsControl(r rune) bool
IsControl проверяет, является ли руна управляющим символом. Категория Юникода C (Other) включает в себя больше кодовых точек, таких как суррогаты; используйте Is(C, r), чтобы проверить их.
func IsDigit
func IsDigit(r rune) bool
IsDigit проверяет, является ли руна десятичной цифрой.

Код:
fmt.Printf("%t\n", unicode.IsDigit('৩'))
fmt.Printf("%t\n", unicode.IsDigit('A'))
Вывод:
true false
func IsGraphic
func IsGraphic(r rune) bool
IsGraphic проверяет, определена ли руна как графический символ Юникодом. Такие символы включают буквы, знаки, цифры, знаки препинания, символы и пробелы из категорий L, M, N, P, S, Zs.
func IsLetter
func IsLetter(r rune) bool
IsLetter проверяет, является ли руна буквой (категория L).
Пример
Код:
fmt.Printf("%t\n", unicode.IsLetter('A'))
fmt.Printf("%t\n", unicode.IsLetter('7'))
Вывод:
true false
func IsLower
func IsLower(r rune) bool

Вывод:
true false
func IsOneOf
func IsOneOf(ranges []*RangeTable, r rune) bool
IsOneOf проверяет, является ли руна членом одного из диапазонов. Функция "In" имеет более удобный синтаксис и должна использоваться вместо IsOneOf.
func IsPrint

Такие символы включают буквы, знаки, цифры, знаки препинания, символы и символ пробела ASCII, из категорий L, M, N, P, S и символ пробела ASCII. Это определение совпадает с IsGraphic, за исключением того, что единственным символом пробела является пробел ASCII, U+0020.

func SimpleFold
func SimpleFold(r rune) rune
SimpleFold итерирует по кодовым точкам Юникода, эквивалентным по простому сложению регистров Юникода. Среди кодовых точек, эквивалентных руне (включая саму руну), SimpleFold возвращает наименьшую руну > r, если она существует, в противном случае — наименьшую руну >= 0. Если r не является допустимой кодовой точкой Юникода, SimpleFold(r) возвращает r.
Например:
SimpleFold('A') = 'a'
SimpleFold('a') = 'A'
SimpleFold('K') = 'k'
SimpleFold('k') = '\u212A' (Kelvin symbol, K)
SimpleFold('\u212A') = 'K'
SimpleFold('1') = '1'
SimpleFold(-2) = -2
Пример
Код:
fmt.Printf("%#U\n", unicode.SimpleFold('A')) // 'a'
fmt.Printf("%#U\n", unicode.SimpleFold('a')) // 'A'
fmt.Printf("%#U\n", unicode.SimpleFold('K')) // 'k'
fmt.Printf("%#U\n", unicode.SimpleFold('k')) // '\u212A' (Kelvin symbol, K)
fmt.Printf("%#U\n", unicode.SimpleFold('\u212A')) // 'K'
fmt.Printf("%#U\n", unicode.SimpleFold('1')) // '1'
Вывод:
U+0061 'a' U+0041 'A' U+006B 'k' U+212A 'K' U+004B 'K' U+0031 '1'
func To
func To(_case int, r rune) rune
To преобразует руну в указанный регистр: UpperCase, LowerCase или TitleCase.
Пример
Код:
const lcG = 'g'
fmt.Printf("%#U\n", unicode.To(unicode.UpperCase, lcG))
fmt.Printf("%#U\n", unicode.To(unicode.LowerCase, lcG))
fmt.Printf("%#U\n", unicode.To(unicode.TitleCase, lcG))
const ucG = 'G'
fmt.Printf("%#U\n", unicode.To(unicode.UpperCase, ucG))
fmt.Printf("%#U\n", unicode.To(unicode.LowerCase, ucG))
fmt.Printf("%#U\n", unicode.To(unicode.TitleCase, ucG))

fmt.Printf("%#U\n", unicode.ToLower(ucG))
Вывод:
U+0067 'g'
func ToTitle
func ToTitle(r rune) rune
ToTitle преобразует руну в прописные буквы.

Пример
Код:
const ucG = 'g'
fmt.Printf("%#U\n", unicode.ToUpper(ucG))
Вывод:
U+0047 'G'
тип CaseRange
CaseRange представляет диапазон кодовых точек Юникода для простого (одна кодовая точка к одной кодовой точке) преобразования регистра. Диапазон охватывает от Lo до Hi включительно, со фиксированным шагом 1. Дельты — это число, которое нужно добавить к кодовой точке, чтобы получить кодовую точку для другого регистра этого символа. Они могут быть отрицательными. Если ноль, это означает, что символ находится в соответствующем регистре. Существует специальный случай, представляющий последовательности чередующихся пар соответствующих символов верхнего и нижнего регистров. Он появляется с фиксированной дельтой
{UpperLower, UpperLower, UpperLower}
Постоянная UpperLower имеет иначе невозможную величину дельты.
type CaseRange struct {
Lo uint32
Hi uint32
Delta d
}
тип Range16
Range16 представляет собой диапазон 16-битных кодовых точек Юникода. Диапазон охватывает от Lo до Hi включительно и имеет указанный шаг.
type Range16 struct {
Lo uint16
Hi uint16
Stride uint16
}
тип Range32
Range32 представляет собой диапазон кодовых точек Юникода и используется, когда одна или несколько значений не помещаются в 16 бит. Диапазон охватывает от Lo до Hi включительно и имеет указанный шаг. Lo и Hi всегда должны быть ≥ 1 << 16.
type Range32 struct {
Lo uint32
Hi uint32
Stride uint32
}
тип RangeTable
RangeTable определяет набор кодовых точек Юникода, перечисляя диапазоны кодовых точек в этом наборе. Диапазоны перечислены в двух срезах для экономии места: срез 16-битных диапазонов и срез 32-битных диапазонов. Два среза должны быть отсортированы по возрастанию и не перекрываться. Также R32 должно содержать только значения ≥ 0x10000 (1 << 16).
type RangeTable struct {
R16 []Range16
R32 []Range32
LatinOffset int // number of entries in R16 with Hi <= MaxLatin1; added in Go 1.1
}
тип SpecialCase
SpecialCase представляет языкоспецифичные преобразования регистра, такие как для турецкого языка. Методы SpecialCase настраивают (переопределяя) стандартные преобразования.
type SpecialCase []CaseRange
var AzeriCase SpecialCase = _TurkishCase
var TurkishCase SpecialCase = _TurkishCase
Пример
Код:
t := unicode.TurkishCase
const lci = 'i'
fmt.Printf("%#U\n", t.ToLower(lci))
fmt.Printf("%#U\n", t.ToTitle(lci))
fmt.Printf("%#U\n", t.ToUpper(lci))
const uci = 'İ'
fmt.Printf("%#U\n", t.ToLower(uci))
fmt.Printf("%#U\n", t.ToTitle(uci))
fmt.Printf("%#U\n", t.ToUpper(uci))
Вывод:
U+0069 'i' U+0130 'İ' U+0130 'İ' U+0069 'i' U+0130 'İ' U+0130 'İ'
func (SpecialCase) ToLower
func (special SpecialCase) ToLower(r rune) rune
ToLower преобразует руну в нижний регистр, отдавая приоритет специальному преобразованию.
func (SpecialCase) ToTitle
func (special SpecialCase) ToTitle(r rune) rune
ToTitle преобразует руну в заглавный регистр, отдавая приоритет специальному преобразованию.
func (SpecialCase) ToUpper
func (special SpecialCase) ToUpper(r rune) rune
ToUpper преобразует руну в верхний регистр, отдавая приоритет специальному преобразованию.
Ошибки
- ☞
Нет механизма для полного преобразования регистра, то есть для символов, которые включают несколько рун на входе или выходе.
