Overview ¶

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

Based on the unicode package, with the following omissions:

No IsGraphic.
No IsMark.
No IsNumber.
No IsPrint.
No IsPunct.
No IsSymbol.
No Properties.
No Scripts.
No SimpleFold.
No SpecialCase.

Example (Is) ¶

Functions starting with "Is" can be used to inspect which table of range a rune belongs to. Note that runes may fit into more than one range.

package main

import (
	"solod.dev/so/fmt"
	"solod.dev/so/unicode"
)

func main() {
	// constant with mixed type runes
	const mixed = "\b5Ὂg̀9! ℃ᾭG"
	for _, c := range mixed {
		fmt.Printf("For %q:\n", c)
		if unicode.IsControl(c) {
			fmt.Println("\tis control rune")
		}
		if unicode.IsDigit(c) {
			fmt.Println("\tis digit rune")
		}
		if unicode.IsLetter(c) {
			fmt.Println("\tis letter rune")
		}
		if unicode.IsLower(c) {
			fmt.Println("\tis lower case rune")
		}
		if unicode.IsSpace(c) {
			fmt.Println("\tis space rune")
		}
		if unicode.IsTitle(c) {
			fmt.Println("\tis title case rune")
		}
		if unicode.IsUpper(c) {
			fmt.Println("\tis upper case rune")
		}
	}

}

Output:
For '\b':
	is control rune
For '5':
	is digit rune
For 'Ὂ':
	is letter rune
	is upper case rune
For 'g':
	is letter rune
	is lower case rune
For '̀':
For '9':
	is digit rune
For '!':
For ' ':
	is space rune
For '℃':
For 'ᾭ':
	is letter rune
	is title case rune
For 'G':
	is letter rune
	is upper case rune

Constants ¶

View Source

const (
	MaxRune         = '\U0010FFFF' // Maximum valid Unicode code point.
	ReplacementChar = '\uFFFD'     // Represents invalid code points.
	MaxASCII        = '\x7f'       // maximum ASCII value.
	MaxLatin1       = '\u00FF'     // maximum Latin-1 value.
)

View Source

const (
	UpperCase = iota
	LowerCase
	TitleCase
	MaxCase
)

Indices into the Delta arrays inside CaseRanges for case mapping.

View Source

const (
	UpperLower = MaxRune + 1 // (Cannot be a valid delta.)
)

If the Delta field of a CaseRange is UpperLower, it means this CaseRange represents a sequence of the form (say) Upper Lower Upper Lower.

const Version = "15.0.0"

Version is the Unicode edition from which the tables are derived.

Variables ¶

View Source

var CaseRanges = []CaseRange{}/* 328 elements not displayed */

CaseRanges is the table describing case mappings for all letters with non-self mappings.

)

func main() {
	const lcG = 'g'

	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))

U+0047 'G'

Types ¶

type CaseRange ¶

type CaseRange struct {
	Lo    uint32
	Hi    uint32
	Delta D
}

CaseRange represents a range of Unicode code points for simple (one code point to one code point) case conversion. The range runs from Lo to Hi inclusive, with a fixed stride of 1. Deltas are the number to add to the code point to reach the code point for a different case for that character. They may be negative. If zero, it means the character is in the corresponding case. There is a special case representing sequences of alternating corresponding Upper and Lower pairs. It appears with a fixed Delta of

{UpperLower, UpperLower, UpperLower}

The constant UpperLower has an otherwise impossible delta value.

type D ¶

type D [MaxCase]rune // to make the CaseRanges text shorter

type Range16 ¶

type Range16 struct {
	Lo     uint16
	Hi     uint16
	Stride uint16
}

Range16 represents of a range of 16-bit Unicode code points. The range runs from Lo to Hi inclusive and has the specified stride.

type Range32 ¶

type Range32 struct {
	Lo     uint32
	Hi     uint32
	Stride uint32
}

Range32 represents of a range of Unicode code points and is used when one or more of the values will not fit in 16 bits. The range runs from Lo to Hi inclusive and has the specified stride. Lo and Hi must always be >= 1<<16.

type RangeTable ¶

type RangeTable struct {
	R16         []Range16
	R32         []Range32
	LatinOffset int // number of entries in R16 with Hi <= MaxLatin1
}

RangeTable defines a set of Unicode code points by listing the ranges of code points within the set. The ranges are listed in two slices to save space: a slice of 16-bit ranges and a slice of 32-bit ranges. The two slices must be in sorted order and non-overlapping. Also, R32 should contain only values >= 0x10000 (1<<16).
