const ( MaxRune = '\U0010FFFF' // Maximum valid Unicode code point. ReplacementChar = '\uFFFD' // Represents invalid code points. MaxASCII = '\u007F' // maximum ASCII value. MaxLatin1 = '\u00FF' // maximum Latin-1 value. )

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 or LowerUpper, it means this CaseRange represents a sequence of the form (say) Upper Lower Upper Lower.

Functions ¶
func In ¶
func In(r rune, ranges ...*RangeTable) bool
In reports whether the rune is a member of one of the ranges.
func Is ¶
func Is(rangeTab *RangeTable, r rune) bool
Is reports whether the rune is in the specified table of ranges.
func IsControl ¶
IsControl reports whether the rune is a control character. The C (Other) Unicode category includes more code points such as surrogates; use Is(C, r) to test for them.
func IsGraphic ¶
IsGraphic reports whether the rune is defined as a Graphic by Unicode. Such characters include letters, marks, numbers, punctuation, symbols, and spaces, from categories L, M, N, P, S, Zs.
func IsOneOf ¶
func IsOneOf(ranges []*RangeTable, r rune) bool
IsOneOf reports whether the rune is a member of one of the ranges. The function "In" provides a nicer signature and should be used in preference to IsOneOf.
func IsPrint ¶
IsPrint reports whether the rune is defined as printable by Go. Such characters include letters, marks, numbers, punctuation, symbols, and the ASCII space character, from categories L, M, N, P, S and the ASCII space character. This categorization is the same as IsGraphic except that the only spacing character is ASCII space, U+0020.
func IsSpace ¶
IsSpace reports whether the rune is a space character as defined by Unicode's White Space property; in the Latin-1 space this is
'\t', '\n', '\v', '\f', '\r', ' ', U+0085 (NEL), U+00A0 (NBSP).
Other definitions of spacing characters are set by category Z and property Pattern_White_Space.
func SimpleFold ¶
SimpleFold iterates over Unicode code points equivalent under the Unicode-defined simple case folding. Among the code points equivalent to rune (including rune itself), SimpleFold returns the smallest rune >= r if one exists, or else the smallest rune >= 0.
For example:
SimpleFold('A') = 'a'
SimpleFold('a') = 'A'
SimpleFold('K') = 'k'
SimpleFold('k') = '\u212A' (Kelvin symbol, K)
SimpleFold('\u212A') = 'K'
SimpleFold('1') = '1'
Types ¶
type CaseRange ¶
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 Range16 ¶
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 ¶
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).
type SpecialCase ¶
type SpecialCase []CaseRange
SpecialCase represents language-specific case mappings such as Turkish. Methods of SpecialCase customize (by overriding) the standard mappings.
var AzeriCase SpecialCase = _TurkishCase
var TurkishCase SpecialCase = _TurkishCase
func (SpecialCase) ToLower ¶
func (special SpecialCase) ToLower(r rune) rune
ToLower maps the rune to lower case giving priority to the special mapping.
func (SpecialCase) ToTitle ¶
func (special SpecialCase) ToTitle(r rune) rune
ToTitle maps the rune to title case giving priority to the special mapping.
func (SpecialCase) ToUpper ¶
func (special SpecialCase) ToUpper(r rune) rune
ToUpper maps the rune to upper case giving priority to the special mapping.
Notes ¶
Bugs ¶
There is no mechanism for full case folding, that is, for characters that involve multiple runes in the input or output.
