User:Ucucha/duplinks.js is a script that highlights links that occur more than once in an article. Per WP:REPEATLINK, terms should generally be linked only once in an article, but there are a number of exceptions to this rule. To account for these exceptions, this script considers only links that are within paragraphs (
<p>...</p> tags) and ignores any links inside an infobox or navbox. In addition, it highlights duplicate links within the lead and within the body of the article separately.
To install the script, add:
importScript('User:Ucucha/duplinks.js'); // [[User:Ucucha/duplinks]]
to Special:MyPage/common.js. There will be a link "Highlight duplicate links" in the toolbox on the left on every mainspace article.
