neollama.nvim

EARLY DEVELOPMENT VERSION/PLAYGROUND. USE AT OWN RISK!!

A minimal Neovim plugin (Lua) to chat with a local Ollama instance in a dedicated chat tab, send visual selections, entire buffers, or a set of added buffers to the model, and keep read-only chat history in that tab.

Features

• :OllamaChat [model] — open a new chat tab with a read-only chat buffer.
• :OllamaAsk {text} — send a one-off prompt to the current chat session.
• :OllamaChatClose — close the chat tab and destroy its buffer.
• :OllamaSendSelection — send the current visual selection as context/prompt.
• :OllamaSendBuffer — send the entire current buffer content.
• :OllamaAddBuffer — add the current buffer to the session's context list.
• :OllamaClearAddedBuffers — clear the context buffer list for the session.
• :OllamaSendAddedBuffers — send the concatenated contents of all added buffers.
• :OllamaModel [model] — set/get model name for the current chat.
• :OllamaSetServer {url} — change the server URL (default: http://127.0.0.1:11434).

The chat buffer is read-only; you interact using commands. History remains visible within the tab.
This plugin uses external curl to call Ollama's HTTP API (/api/generate) either buffered/streamed to neovim, or not (set in config with stream=true|false).

Requirements

• Neovim 0.8+
• A running Ollama server (default: http://127.0.0.1:11434)
• curl available on your system

Installation

Lazy.nvim

{
  "thgrass/neollama.nvim",
  config = function()
    require("ollama_chat").setup({
      server_url = "http://127.0.0.1:11434",
      model = "llama3.1",
      stream = true,
    })
  end,
}

Packer.nvim

• From another buffer, send the current visual selection:

  • Select text in Visual mode, then:

    :OllamaSendSelection

  :OllamaAddBuffer           " run in buffers you want to add
  :OllamaSendAddedBuffers    " send all added buffers together
  :OllamaClearAddedBuffers   " clear the list

• Change model for the current chat:

  :OllamaModel mistral      " set model to mistral  
  :OllamaModel              " prints current model

• Change server URL:

  :OllamaSetServer http://localhost:11434
