nvim-bard

nvim-bard is a minimal plugin to interact with Bard using bardapi python package.

Important

Writing this plugin was a lot of fun, but I don't recommend using it for anything other than experimentation.
It works with bardapi which is not an official API and which can stop working at the slightest change in Bard's policy. Since August, it seems that it is necessary to update the cookie values regularly.
Also, this AI is quite slow and seems to me less efficient than ChatGPT for coding.

Requirements

This plugin requires bardapi

pip install bardapi

Bard API key

1. Go to bard.google.com
2. Open developer tools
3. Go to Application
4. Go to Cookies
5. Copy the content of __Secure-1PSID in nvim-bard config (bard_api_key)

Installation with config

lazy.nvim

{
  'martineausimon/nvim-bard',
  dependencies = 'MunifTanjim/nui.nvim', -- only for "popup" mode
  config = function()
    require('nvim-bard').setup({
      bard_api_key = "", --required
      display_mode = "popup", -- "popup", "vsplit" or "tabnew"
      mappings = {
        toggle_bard = "<leader>b",
        hide_bard = { "q", "<esc>" },
        send_bard = "<cr>",
        new_chat = "<c-n>"
      },
      options = {
        ui = {
          question = {
            signs = {
              sign = "",
              hi = "Function",
              style = "single" -- "double", "none", "rounded", "solid"
            },
            border = { -- only for "popup" mode
              style = "single", -- "double", "none", "shadow", "rounded", "solid"
              text = {
                top = "[Prompt]"
              }
            },
            winhighlight = "Normal:Normal,FloatBorder:Normal"
          },
          bard = {
            signs = {
              sign = "🟆",
              hi = "Statement",
              style = "single"
            },
            border = {
              style = "single",
              text = {
                top = "[Bard]"
              }
            },
            winhighlight = "Normal:Normal,FloatBorder:Normal"
          }
        },
        buffer_options = {
          signcolumn = 'yes:1',
          filetype = 'markdown',
          conceallevel = 3,
          buftype = "nofile",
        },
      }
    })
  end
}

Since august, Bard has updated it's policy and settings for different regions and you may need to set bard_api_key this way, retrieving the values from Secure-1PSID, Secure-1PSIDCC, et Secure-1PSIDTS :

require('nvim-bard').setup({
  bard_api_key = {
    psid   = "xxxx",
    psidcc = "xxxx",
    psidts = "xxxx"
  },
}

⚠ __Secure-1PSID is private ! If you don't want to write this Bard API key in your config directly, you can store it in a local file (e.g. $HOME/.bard_api_key), and use the following function:

local api_key
local file = io.open('/home/user/.bard_api_key', 'r')
if file then
  api_key = file:read()
  file:close()
end

{
  'martineausimon/nvim-bard',
  dependencies = 'MunifTanjim/nui.nvim',
  config = function()
    require('nvim-bard').setup({
      bard_api_key = api_key,
    })
  end
}
