package cases

import "golang.org/x/text/cases"

Package cases provides general and language-specific case mappers.

Code:

src := []string{
    "hello world!",
    "i with dot",
    "'n ijsberg",
    "here comes O'Brian",
}
for _, c := range []cases.Caser{
    cases.Lower(language.Und),
    cases.Upper(language.Turkish),
    cases.Title(language.Dutch),
    cases.Title(language.Und, cases.NoLower),
} {
    fmt.Println()
    for _, s := range src {
        fmt.Println(c.String(s))
    }
}

Output:

hello world!
i with dot
'n ijsberg
here comes o'brian

HELLO WORLD!
İ WİTH DOT
'N İJSBERG
HERE COMES O'BRİAN

Hello World!
I With Dot
'n IJsberg
Here Comes O'brian

Hello World!
I With Dot
'N Ijsberg
Here Comes O'Brian

cases.go context.go fold.go info.go map.go tables9.0.0.go trieval.go

Constants

const UnicodeVersion = "9.0.0"

UnicodeVersion is the Unicode version from which the tables in this package are derived.

Variables

var (
    Supported language.Coverage
)

type Caser Uses

type Caser struct {
    // contains filtered or unexported fields
}

A Caser transforms given input to a certain case. It implements transform.Transformer.

A Caser may be stateful and should therefore not be shared between goroutines.

func Fold Uses

func Fold(opts ...Option) Caser

Fold returns a Caser that implements Unicode case folding. The returned Caser is stateless and safe to use concurrently by multiple goroutines.

Case folding does not normalize the input and may not preserve a normal form. Use the collate or search package for more convenient and linguistically sound comparisons. Use golang.org/x/text/secure/precis for string comparisons where security aspects are a concern.

func Lower Uses

func Lower(t language.Tag, opts ...Option) Caser

Lower returns a Caser for language-specific lowercasing.

func Title Uses

func Title(t language.Tag, opts ...Option) Caser

Title returns a Caser for language-specific title casing. It uses an approximation of the default Unicode Word Break algorithm.

func Upper Uses

func Upper(t language.Tag, opts ...Option) Caser

Upper returns a Caser for language-specific uppercasing.

func (Caser) Bytes Uses

func (c Caser) Bytes(b []byte) []byte

Bytes returns a new byte slice with the result of converting b to the case form implemented by c.

func (Caser) Reset Uses

func (c Caser) Reset()

Reset resets the Caser to be reused for new input after a previous call to Transform.

func (Caser) Span Uses

func (c Caser) Span(src []byte, atEOF bool) (n int, err error)

Span implements the transform.SpanningTransformer interface.

func (Caser) String Uses

func (c Caser) String(s string) string

String returns a string with the result of transforming s to the case form implemented by c.

func (Caser) Transform Uses

func (c Caser) Transform(dst, src []byte, atEOF bool) (nDst, nSrc int, err error)

Transform implements the transform.Transformer interface and transforms the given input to the case form implemented by c.

type Option Uses

type Option func(o options) options

An Option is used to modify the behavior of a Caser.

var (
    // NoLower disables the lowercasing of non-leading letters for a title
    // caser.
    NoLower Option = noLower

    // Compact omits mappings in case folding for characters that would grow the
    // input. (Unimplemented.)
    Compact Option = compact
)

func HandleFinalSigma Uses

func HandleFinalSigma(enable bool) Option

HandleFinalSigma specifies whether the special handling of Greek final sigma should be enabled. Unicode prescribes handling the Greek final sigma for all locales, but standards like IDNA and PRECIS override this default.
