looks like a nice tool for evaluating code blocks directly in Vim's Markdown buffers, and the ability to redirect outputs into named blocks is a cool way to keep everything contained in the editor. If you're looking for something similar but more versatile across different environments, check out *Cog*. It embeds executable code in any text file and inserts the output back into the document, which is great for automating documentation outside of Vim, especially in CI pipelines.
