Vani

vani is a lightweight LSP server that provides English word completions and definitions for plain text files.

---

✨ Features

• English word auto-completion
• Hover support to show definitions
• Works with Neovim via native LSP

---

🧩 Usage (Neovim)

1. Download or build the binary

go build -o vani main.go
# or download prebuilt binaries

Place it somewhere in your $PATH or give the absolute path in config.

---

2. Create LSP client config (e.g. lua/lsp/vani.lua)

-- lua/lsp/vani.lua

local client_id = vim.lsp.start({
  name = 'vani',
  cmd = { 'path/to/vani' }, -- replace with actual binary path
})

if not client_id then
  vim.notify("Vani LSP: failed to start client", vim.log.levels.ERROR)
  return
end

vim.api.nvim_create_autocmd("BufReadPost", {
  pattern = "text", -- or "markdown", etc.
  callback = function(args)
    local ok = vim.lsp.buf_is_attached(args.buf, client_id)
    if not ok then
      vim.lsp.buf_attach_client(args.buf, client_id)
    end
  end
})

---

3. Register it in lspconfig

-- plugins/lspconfig.lua
return {
  "neovim/nvim-lspconfig",
  config = function()
    -- other LSPs
    require("lsp.vani") -- path to your vani config
  end,
}

---

🗂️ TODO

• VSCode extension
• Add persistent DB for definitions

---

💡 Notes

• Definitions are fetched live (not persistent yet)
