Does the library support this functionality or is there a way to get this information?\r\n\r\nThanks again for the support.","author":{"url":"https://github.com/Devy99","@type":"Person","name":"Devy99"},"datePublished":"2024-01-08T20:08:29.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/4/code_diff/issues/4"}
