+# linebreak
+An implementation of the Unicode Line Breaking Algorithm (UAX #14)
+
+> 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.
+
+This is a JavaScript implementation of the [Unicode Line Breaking Algorithm](http://www.unicode.org/reports/tr14/#SampleCode) for Node.js
+(and browsers I guess). Currently supports Unicode version 13. It is used by [PDFKit](http://github.com/devongovett/pdfkit/) for
+line wrapping text in PDF documents, but since the algorithm knows nothing about the actual visual appearance or layout of text, 
+it could be used for other things as well.
+
+## Installation
+
+You can install via npm
+
+    npm install linebreak
+
+## Example
+
+```javascript
+var LineBreaker = require('linebreak');
+
+var lorem = 'lorem ipsum...';
+var breaker = new LineBreaker(lorem);
+var last = 0;
+var bk;
+
+while (bk = breaker.nextBreak()) {
+  // get the string between the last break and this one
+  var word = lorem.slice(last, bk.position);
+  console.log(word);
+
+  // you can also check bk.required to see if this was a required break...
+  if (bk.required) {
+    console.log('\n\n');
+  }
+
+  last = bk.position;
+}
+```
+
+## Development Notes
+
+In order to use the library, you shouldn't need to know this, but if you're interested in
+contributing or fixing bugs, these things might be of interest.
+
+* The `src/classes.js` file is automatically generated from `LineBreak.txt` in the Unicode
+  database by `src/generate_data.js`. It should be rare that you need to run this, but
+  you may if, for instance, you want to change the Unicode version.
+
+* You can run the tests using `npm test`. They are written using `mocha`, and generated from
+  `LineBreakTest.txt` from the Unicode database, which is included in the repository for performance
+  reasons while running them. About 50 of the over 7600 tests are currently skipped due to
+  implementation differences. It appears that some of the tests may be wrong or use different
+  tailoring from the spec.
