LatinExtendedAdditionalMapping contains a slice of all string transformers chained together which is used as additional mapping for PRECIS profile.

var LatinExtendedPrecisProfile = precis.NewFreeform(
	precis.FoldWidth,
	precis.AdditionalMapping(func() transform.Transformer {
		return transform.Chain(LatinExtendedAdditionalMapping...)
	}),
	precis.FoldCase(cases.HandleFinalSigma(true)),
)

LatinExtendedPrecisProfile is a Unicode PRECIS profile which prepare strings for a more secure comparison.

var LatinExtendedSanitize = factory.MakeStringTransformFunction(
	LatinExtendedPrecisProfile.NewTransformer(),
)

LatinExtendedSanitize sanitizes an input string via various string sanitization methods related to Extended Latin scripts.

var RespaceTransformer transform.SpanningTransformer = &respaceSpanningTransformer{}

RespaceTransformer is a Unicode stream transformer object which removes all leading and trailing white-spaces, then it reduces all inter-word white-spaces into a single normal space.

var StripNonPrintTransformer = runes.Remove(runes.NotIn(runedata.PrintsAndWhiteSpaces))

StripNonPrintingTransform is a Unicode stream transformer object which removes all occurrences of non-printing and non-spacing rune characters from a string.

var ToNormalHyphenTransformer = runes.Map(func(r rune) rune {
	if unicode.Is(runedata.HyphensAndDashes, r) {
		return '-'
	}
	return r
})

ToNormalHyphenTransformer is a Unicode stream transformer object which replaces all dash or hyphen characters into a normal hyphen.

var ToNormalSpaceTransformer = runes.Map(func(r rune) rune {
	if unicode.Is(unicode.White_Space, r) {
		return ' '
	}
	return r
})

ToNormalSpaceTransformer is a Unicode stream transformer object which replaces all white space rune characters into a normal space.
