/**
* @class Autolinker
* @extends Object
*
* Utility class used to process a given string of text, and wrap the matches in
* the appropriate anchor (<a>) tags to turn them into links.
*
* Any of the configuration options may be provided in an Object provided
* to the Autolinker constructor, which will configure how the {@link #link link()}
* method will process the links.
*
* For example:
*
* var autolinker = new Autolinker( {
* newWindow : false,
* truncate : 30
* } );
*
* var html = autolinker.link( "Joe went to www.yahoo.com" );
* // produces: 'Joe went to <a href="http://www.yahoo.com">yahoo.com</a>'
*
*
* The {@link #static-link static link()} method may also be used to inline
* options into a single call, which may be more convenient for one-off uses.
* For example:
*
* var html = Autolinker.link( "Joe went to www.yahoo.com", {
* newWindow : false,
* truncate : 30
* } );
* // produces: 'Joe went to <a href="http://www.yahoo.com">yahoo.com</a>'
*
*
* ## Custom Replacements of Links
*
* If the configuration options do not provide enough flexibility, a {@link #replaceFn}
* may be provided to fully customize the output of Autolinker. This function is
* called once for each URL/Email/Phone#/Hashtag/Mention (Twitter, Instagram, Soundcloud)
* match that is encountered.
*
* For example:
*
* var input = "..."; // string with URLs, Email Addresses, Phone #s, Hashtags, and Mentions (Twitter, Instagram, Soundcloud)
*
* var linkedText = Autolinker.link( input, {
* replaceFn : function( match ) {
* console.log( "href = ", match.getAnchorHref() );
* console.log( "text = ", match.getAnchorText() );
*
* switch( match.getType() ) {
* case 'url' :
* console.log( "url: ", match.getUrl() );
*
* if( match.getUrl().indexOf( 'mysite.com' ) === -1 ) {
* var tag = match.buildTag(); // returns an `Autolinker.HtmlTag` instance, which provides mutator methods for easy changes
* tag.setAttr( 'rel', 'nofollow' );
* tag.addClass( 'external-link' );
*
* return tag;
*
* } else {
* return true; // let Autolinker perform its normal anchor tag replacement
* }
*
* case 'email' :
* var email = match.getEmail();
* console.log( "email: ", email );
*
* if( email === "my@own.address" ) {
* return false; // don't auto-link this particular email address; leave as-is
* } else {
* return; // no return value will have Autolinker perform its normal anchor tag replacement (same as returning `true`)
* }
*
* case 'phone' :
* var phoneNumber = match.getPhoneNumber();
* console.log( phoneNumber );
*
* return '<a href="http://newplace.to.link.phone.numbers.to/">' + phoneNumber + '</a>';
*
* case 'hashtag' :
* var hashtag = match.getHashtag();
* console.log( hashtag );
*
* return '<a href="http://newplace.to.link.hashtag.handles.to/">' + hashtag + '</a>';
*
* case 'mention' :
* var mention = match.getMention();
* console.log( mention );
*
* return '<a href="http://newplace.to.link.mention.to/">' + mention + '</a>';
* }
* }
* } );
*
*
* The function may return the following values:
*
* - `true` (Boolean): Allow Autolinker to replace the match as it normally
* would.
* - `false` (Boolean): Do not replace the current match at all - leave as-is.
* - Any String: If a string is returned from the function, the string will be
* used directly as the replacement HTML for the match.
* - An {@link Autolinker.HtmlTag} instance, which can be used to build/modify
* an HTML tag before writing out its HTML text.
