ROFL checks what you say about your code. A notebook (.rofl.md) is
Markdown with sentences, rules and questions; it answers the questions and
marks every never that fails, on the line in your code where it fails.
Use it
Open any .rofl.md file: it opens as a notebook. Press Run All.
New here? Play the tutorial: six short levels, one new word each.
Get it with the rofl-nb command, or from
GitHub.
A .rofl file gets errors on their lines, hover, go to definition and
completion.
No telemetry. Nothing leaves your machine, except:
Translate (natural-language cells) sends the notebook text to the model you
chose: VS Code's language model (e.g. Copilot) or a CLI (ROFL: Choose model).
A notebook reads the code files its front matter names, so it runs only
in a trusted workspace.
