A JavaScript library for Line Breaking and identifying Word Boundaries,
|
||||
[implementing the Unicode Line Breaking Algorithm (UAX #14)](http://unicode.org/reports/tr14/)
|
||||
|
||||
>> Line breaking, also known as word wrapping, is the process of breaking a section of text into
|
||||
lines such that it will fit in the available width of a page, window or other display area.
|
||||
The Unicode Line Breaking Algorithm performs part of this process. Given an input text,
|
||||
it produces a set of positions called "break opportunities" that are appropriate points to
|
||||
begin a new line. The selection of actual line break positions from the set of break opportunities
|
||||
is not covered by the Unicode Line Breaking Algorithm, but is in the domain of higher level
|
||||
software with knowledge of the available width and the display size of the text.
|
||||
|
||||
In addition, the module implements CSS specific tailoring options to line breaking as
|
||||
defined in [CSS Text Module Level 3](https://www.w3.org/TR/css-text-3/#line-breaking).
|
||||
|
||||
### Installing
|
||||
You can install the module via npm:
|
||||
|
||||
npm install css-line-break
|
||||
|
||||
### Usage
|
||||
The `LineBreaker` creates an [iterator](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Iterators_and_Generators) that returns `Break`s for a given text.
|
||||
|
||||
LineBreaker(text, [options]);
|
||||
|
||||
### Example
|
||||
[JSFiddle](https://jsfiddle.net/ofd3752k)
|
||||
```javascript
|
||||
import {LineBreaker} from 'css-line-break';
|
||||
|
||||
const breaker = LineBreaker('Lorem ipsum lol.', {
|
||||
lineBreak: 'strict',
|
||||
wordBreak: 'normal'
|
||||
});
|
||||
|
||||
const words = [];
|
||||
let bk;
|
||||
|
||||
while (!(bk = breaker.next()).done) {
|
||||
words.push(bk.value.slice());
|
||||
}
|
||||
|
||||
assert.deepEqual(words, ['Lorem ', 'ipsum ', 'lol.']);
|
||||
```
|
||||
### Options
|
||||
The following parameters are available for the options:
|
||||
|
||||
- `lineBreak`: `normal` | `strict`
|
||||
- `wordBreak`: `normal` | `break-all` | `break-word` | `keep-all`
|
||||
|
||||
For more information how they affect the line breaking algorithms,
|
||||
check out [CSS Text Module Level 3](https://www.w3.org/TR/css-text-3/#line-breaking).
|
||||
|
||||
### Testing
|
||||
You can run the test suite with:
|
||||
|
||||
npm test
|
||||
|
||||
The library implements all the [LineBreakTest.txt tests](http://www.unicode.org/Public/10.0.0/ucd/auxiliary/LineBreakTest.txt)
|
||||
and a number of CSS web-platform-tests.
