Aniseed
Neovim configuration and plugins in Fennel (Lisp compiled to Lua)
...For interactive evaluation, you need to install Conjure as well. It’ll allow you to send portions of your code off for evaluation as well as see the results in an interactive log buffer. Aniseed ships with a set of module macros that make interactive evaluation not only possible but rich and intuitive. You should read:h aniseed to learn the details but it’s worth mentioning that you opt-in by starting your file with a (module …) block, you then export values from your module with the (def…) macros.
