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) |
|
} |
|
|
|
*/ |
