The author recreated the "Bad Apple!!" animation within Vim using an incredibly unconventional method: thousands of regular expressions. Instead of manipulating images directly, they constructed 6,500 unique regex searches, each designed to highlight specific character patterns within a specially prepared text file. When run sequentially, these searches effectively "draw" each frame of the animation by selectively highlighting characters that visually approximate the shapes and shading. This process is exceptionally slow and resource-intensive, pushing Vim to its limits, but results in a surprisingly accurate, albeit flickering, rendition of the iconic video entirely within the text editor.
Hacker News commenters generally expressed amusement and impressed disbelief at the author's feat of rendering Bad Apple!! in Vim using thousands of regex searches. Several pointed out the inefficiency and absurdity of the method, highlighting the vast difference between text manipulation and video rendering. Some questioned the practical applications, while others praised the creativity and dedication involved. A few commenters delved into the technical aspects, discussing Vim's handling of complex regex operations and the potential performance implications.
