ftplugin in fennel?

[ajayvigneshk]

Hey! Just curious, is it possible to write ftplugin configs in fennel and have hotpot compile it into lua?

[bangedorrunt]

I don't think it's feasible with Hotpot at the moment. You can use Fennel binary file to compile it manually though.

This is correct, because hotpot acts as a lua loader, it doesn't really interact with the ftplugins dir, as neovim doesn't consult the regular lua loader path for those. What you could do is something like

fnl/
  /my-config
    /ftplugins
      /elixir.fnl
/ftplugin
  /elixir.lua <- "require("my-config.ftplugins.elixir")

Not great but it should work and once the lua bytecode loader stuff is worked out it's probably no slower really.

Thanks @rktjmp . Makes sense

Is there a way to do something like this manually to load the Fennel code?

That's a mighty big brain you've got there, not sure why I never thought to add a FileType autocommand.

;; in your config
(let [{: nvim_create_autocmd : nvim_create_augroup} vim.api
      au-group (nvim_create_augroup :hotpot-ft {})
      cb #(pcall require (.. :ftplugin. (vim.fn.expand "<amatch>")))]
  (nvim_create_autocmd :FileType {:callback cb :group au-group}))

;; ~/.config/nvim/ftplugin/wow.fnl
(print :wow!)

"in vim
:set ft=wow
" wow!

For now you can drop that or similar in your config and I will mainline it soon. It may end up behind a flag as there is perhaps some performance implications there when we search the RTP twice, once for us, then again for the normal stuff. Searching the RTP can be slow.

Excellent, thank you!
