history
Project history and usage
Cornelis is a Neovim interface for Agda, positioning itself as agda-mode for Neovim. It is written in Haskell and exposes Agda interactions through Vim commands for loading, goals, refinement, case splitting, normalization, and navigation.
Project history
The upstream README still describes Cornelis in relation to Emacs agda-mode and documents installation through common Vim and Neovim plugin managers. The current repository under the Agda organization was created in 2022, and its README states that the repository is currently unmaintained while asking interested maintainers to contact the Agda community.
Adoption history
Cornelis serves the smaller intersection of Agda users and Neovim users. Its adoption significance is mainly editorial and workflow-based: it gives dependently typed programming a modal-editor path rather than requiring the traditional Emacs-centered Agda workflow.
How it is used
Users install Cornelis as a Neovim plugin, build it with Stack, and configure Vimscript or Lua variables for behavior such as rewrite mode, Agda input prefix, disabling default bindings, and debug logging.
Why package nerds care
Cornelis is interesting to package maintainers because it is both an editor integration and a Haskell-built executable. Distribution needs to account for Neovim plugin layout, Stack/Haskell build expectations, and compatibility with Agda versions.
