    Doesn't look like it is been updated in a while. And the GitHub repos last commits are even older. Dead project?

      I think that's probably unlikely given the long list of universities using it[0].

      It's an educational tool for formal propositional logic which hasn't really changed much on 100 years, so probably not a lot of updates are required unless there are big new updates to Haskell itself.

      Or maybe it's finished ?

        It seems to of had the web app portion updated a year ago. And as you say, the application itself looks ‘done.’

        I have frequently used Common Lisp over the last 40 years, and I hear comments about libraries being old and not updated in many years: so what! Quality code that performs a specific function sometimes is ‘done.’

        I am a novice Haskell programmer but I enjoy the language and it is very cool to have the Carnap github repo with a book manuscript, backend and front end code to look over.

    If you were wondering, the name comes from a famous philosopher and logician:

    Past experience in logical frameworks tend to specify documentclass: script, letter, report, etc.
