Examples and Tips

Quick Chat with Buffer

Set up a quick chat command that uses the entire buffer content:

-- Quick chat keybinding
vim.keymap.set('n', '<leader>ccq', function()
  local input = vim.fn.input("Quick Chat: ")
  if input ~= "" then
    require("CopilotChat").ask(input, {
      selection = require("CopilotChat.select").buffer
    })
  end
end, { desc = "CopilotChat - Quick chat" })

Inline Chat Window

Configure the chat window to appear inline near the cursor:

require("CopilotChat").setup({
  window = {
    layout = 'float',
    relative = 'cursor',
    width = 1,
    height = 0.4,
    row = 1
  }
})

Quick Search with Perplexity

Requires PerplexityAI Agent:

vim.keymap.set({ 'n', 'v' }, '<leader>ccs', function()
  local input = vim.fn.input("Perplexity: ")
  if input ~= "" then
    require("CopilotChat").ask(input, {
      agent = "perplexityai",
      selection = false,
    })
  end
end, { desc = "CopilotChat - Perplexity Search" })

Markdown Rendering

Use render-markdown.nvim for better chat display:

-- Register copilot-chat filetype
require('render-markdown').setup({
  file_types = { 'markdown', 'copilot-chat' },
})

-- Adjust chat display settings
require('CopilotChat').setup({
  highlight_headers = false,
  separator = '---',
  error_header = '> [!ERROR] Error',
})
