jet.ark is an Neovim plugin which extends jet.nvim to provide language features for R using the Ark jupyter kernel.

• R console implemented via Jet
• R 'expression' detection, allowing you to send units of code with a single keystroke
• A LSP server which is aware of your R session (e.g. providing completions for dataframe column names and other session-specific stuff)
• Debug adaptor is TODO

You'll need to install Ark and tell jet.ark where the binary lives. In the future this plugin will handle downloading Ark for you.

-- You'll need to include both jet.nvim and jet.ark
vim.pack.add({ "https://github.com/wurli/jet.nvim" })
vim.pack.add({ "https://github.com/wurli/jet.ark" })

require("jet").setup({})
require("jet.ark").setup({
	ark_binary_path = "path-to-ark-binary",
})

Use :Jet repl to open R. Ark's LSP will start automatically and attach to any R buffer you have open.

-- You can set a keymap to toggle the R console like so
vim.keymap.set("n", "<leader>jr", function()
	require("jet.core.api").get_any({ filetype = "r" }, {}, function(k)
		k:toggle_term()
	end)
end, { desc = "Open R (Jet)" })
