Wrap text at specified width. New Observable notebook. I built this with the help of Claude 3 Opus—it’s a text wrapping tool which lets you set the width and also lets you optionally add a four space indent.
The four space indent is handy for posting on forums such as Hacker News that treat a four space indent as a code block.
