# Readability.js

|
|
A standalone version of the readability library used for Firefox Reader View. Any changes to Readability.js itself should be reviewed by an appropriate Firefox/toolkit peer, such as [@leibovic](https://github.com/leibovic) or [@thebnich](https://github.com/thebnich), since these changes will be automatically merged to mozilla-central.

|
|
To test local changes to Readability.js, you can run your own instance of [readable-proxy](https://github.com/n1k0/readable-proxy/) to compare an original test page to its reader-ized content.
|
|
|
|
## Usage
|
|
|
|
To parse a document, you must create a new `Readability` object from a URI object and a document, and then call `parse()`. Here's an example:
|
|
|
|
```javascript
|
|
var location = document.location;
|
|
var uri = {
|
|
spec: location.href,
|
|
host: location.host,
|
|
prePath: location.protocol + "//" + location.host,
|
|
scheme: location.protocol.substr(0, location.protocol.indexOf(":")),
|
|
pathBase: location.protocol + "//" + location.host + location.pathname.substr(0, location.pathname.lastIndexOf("/") + 1)
|
|
};
|
|
var article = new Readability(uri, document).parse();
|
|
```
|
|
|
|
This `article` object will contain the following properties:
|
|
|
|
* `uri`: original `uri` object that was passed to constructor
|
|
* `title`: article title
|
|
* `content`: HTML string of processed article content
|
|
* `length`: length of article, in characters
|
|
* `excerpt`: article description, or short excerpt from content
|
|
* `byline`: author metadata
|
|
* `dir`: content direction
|
|
|
|
## Tests
|
|
|
|
To run the test suite:
|
|
|
|
$ mocha test/test-*.js
|
|
|
|
To run a specific test page by its name:
|
|
|
|
$ mocha test/test-*.js -g 001
|
|
|
|
To run the test suite in TDD mode:
|
|
|
|
$ mocha test/test-*.js -w
|
|
|
|
Combo time:
|
|
|
|
$ mocha test/test-*.js -w -g 001
|
|
|
|
## Benchmarks
|
|
|
|
Benchmarks for all test pages:
|
|
|
|
$ npm run perf
|
|
|
|
Reference benchmark:
|
|
|
|
$ npm run perf-reference
