RBBI for Go

This is a Go port of ICU4C's Rule-Based Break Iterator (RBBI), an algorithm for extracting various types of breaks (character/grapheme cluster, line, sentence, and word) from unicode strings. It supports both forward and reverse iteration.

How to use

Using the break iterater consists of two easy steps:

Instantiate a RBBI instance using one of the four constructors, e.g. NewCharacterRBBI() for character break detection.
Provide the break iterator with a struct implementing the Cursor interface. For iteration over simple strings the StringCursor struct can be used, and for more complex backing stores the interface can be implemented using e.g. a wrapper struct.

Of course, a simple code example is worth a thousand words:

str := "the string to iterate over"
cursor := rbbi.NewStringCursor(str)

iter := rbbi.NewCharacterRBBI()
iter.SetCursor(cursor)

for {
    position, ok := iter.Next()

    if !ok {
        break
    }

    fmt.Println("Found a break at offset %v", position)
}
