- * Library for simple URI parsing and manipulation. Requires jQuery.
+ * Library for simple URI parsing and manipulation. Dependencies: mw, jQuery.
*
- * Do not expect full RFC 3986 compliance. Intended to be minimal, but featureful.
- * The use cases we have in mind are constructing 'next page' or 'previous page' URLs,
- * detecting whether we need to use cross-domain proxies for an API, constructing
- * simple URL-based API calls, etc.
+ * Intended to be minimal, but featureful; do not expect full RFC 3986 compliance. The use cases we
+ * have in mind are constructing 'next page' or 'previous page' URLs, detecting whether we need to
+ * use cross-domain proxies for an API, constructing simple URL-based API calls, etc. Parsing here
+ * is regex-based, so may not work on all URIs, but is good enough for most.
*
- * Intended to compress very well if you use a JS-parsing minifier.
+ * You can modify the properties directly, then use the #toString method to extract the full URI
+ * string again. Example:
*
- * Dependencies: mw, jQuery
+ * var uri = new mw.Uri( 'http://example.com/mysite/mypage.php?quux=2' );
*
- * Example:
- *
- * var uri = new mw.Uri( 'http://foo.com/mysite/mypage.php?quux=2' );
- *
- * if ( uri.host == 'foo.com' ) {
- * uri.host = 'www.foo.com';
+ * if ( uri.host == 'example.com' ) {
+ * uri.host = 'foo.example.com';
* uri.extend( { bar: 1 } );
*
* $( 'a#id1' ).attr( 'href', uri );
- * // anchor with id 'id1' now links to http://foo.com/mysite/mypage.php?bar=1&quux=2
+ * // anchor with id 'id1' now links to http://foo.example.com/mysite/mypage.php?bar=1&quux=2
*
* $( 'a#id2' ).attr( 'href', uri.clone().extend( { bar: 3, pif: 'paf' } ) );
- * // anchor with id 'id2' now links to http://foo.com/mysite/mypage.php?bar=3&quux=2&pif=paf
+ * // anchor with id 'id2' now links to http://foo.example.com/mysite/mypage.php?bar=3&quux=2&pif=paf
* }
*
- * Parsing here is regex based, so may not work on all URIs, but is good enough for most.
- *
* Given a URI like
- * 'http://usr:pwd@www.test.com:81/dir/dir.2/index.htm?q1=0&&test1&test2=&test3=value+%28escaped%29&r=1&r=2#top':
- * The returned object will have the following properties:
+ * `http://usr:pwd@www.example.com:81/dir/dir.2/index.htm?q1=0&&test1&test2=&test3=value+%28escaped%29&r=1&r=2#top`
+ * the returned object will have the following properties:
*
- * protocol 'http'
- * user 'usr'
- * password 'pwd'
- * host 'www.test.com'
- * port '81'
- * path '/dir/dir.2/index.htm'
- * query {
- * q1: 0,
- * test1: null,
- * test2: '',
- * test3: 'value (escaped)'
- * r: [1, 2]
- * }
- * fragment 'top'
+ * protocol 'http'
+ * user 'usr'
+ * password 'pwd'
+ * host 'www.example.com'
+ * port '81'
+ * path '/dir/dir.2/index.htm'
+ * query {
+ * q1: '0',
+ * test1: null,
+ * test2: '',
+ * test3: 'value (escaped)'
+ * r: ['1', '2']
+ * }
+ * fragment 'top'
*
- * n.b. 'password' is not technically allowed for HTTP URIs, but it is possible with other
- * sorts of URIs.
- * You can modify the properties directly. Then use the toString() method to extract the
- * full URI string again.
