Package segment is a library for performing Unicode Text Segmentation
|
|
as described in Unicode Standard Annex #29 http://www.unicode.org/reports/tr29/
|
|
|
|
Currently only segmentation at Word Boundaries is supported.
|
|
|
|
The functionality is exposed in two ways:
|
|
|
|
1. You can use a bufio.Scanner with the SplitWords implementation of SplitFunc.
|
|
The SplitWords function will identify the appropriate word boundaries in the input
|
|
text and the Scanner will return tokens at the appropriate place.
|
|
|
|
scanner := bufio.NewScanner(...)
|
|
scanner.Split(segment.SplitWords)
|
|
for scanner.Scan() {
|
|
tokenBytes := scanner.Bytes()
|
|
}
|
|
if err := scanner.Err(); err != nil {
|
|
t.Fatal(err)
|
|
}
|
|
|
|
2. Sometimes you would also like information returned about the type of token.
|
|
To do this we have introduce a new type named Segmenter. It works just like Scanner
|
|
but additionally a token type is returned.
|
|
|
|
segmenter := segment.NewWordSegmenter(...)
|
|
for segmenter.Segment() {
|
|
tokenBytes := segmenter.Bytes())
|
|
tokenType := segmenter.Type()
|
|
}
|
|
if err := segmenter.Err(); err != nil {
|
|
t.Fatal(err)
|
|
}
|
|
|
|
