bggj.bsky.social @bggj.bsky.social · 25/10/2024Just a heads up: If you're not using version control, never ever ever write "output-dir: ." or similar in your _quarto.yml file. It will delete everything in the base folder recursively (since it wants to refresh the output with this new setting). Luckily, I was using version control. 030
