    "coder/claudecode.nvim"
  },
  opts = {
    auto_context = true,
    batch_size = 10,
    -- 可选：配置键位映射（默认为空，不会占用任何按键）

      grep = "<leader>cg", 
      buffers = "<leader>cb",
      git_files = "<leader>cgf",
      directory_files = "<leader>cd",
    },
  },
  cmd = { "ClaudeFzf", "ClaudeFzfFiles", "ClaudeFzfGrep", "ClaudeFzfBuffers", "ClaudeFzfGitFiles", "ClaudeFzfDirectory" },
  -- 或者使用 lazy.nvim 的 keys 配置（二选一）
  -- keys = {
  --   { "<leader>cf", "<cmd>ClaudeFzfFiles<cr>", desc = "Claude: Add files" },
  --   { "<leader>cg", "<cmd>ClaudeFzfGrep<cr>", desc = "Claude: Search and add" },

    level = "INFO",              -- TRACE, DEBUG, INFO, WARN, ERROR
    file_logging = true,         -- Enable file logging

    show_caller = true,          -- Show caller location
    timestamp = true,            -- Show timestamps
  },

  -- Keymap settings (默认为空，需要主动配置才生效)
  keymaps = {
    files = "<leader>cf",            -- File picker (设置为空字符串 "" 禁用)
    grep = "<leader>cg",             -- Search picker (设置为空字符串 "" 禁用)
    buffers = "<leader>cb",          -- Buffer picker (设置为空字符串 "" 禁用)
    git_files = "<leader>cgf",       -- Git files picker (设置为空字符串 "" 禁用)
    directory_files = "<leader>cd",  -- Directory files picker (设置为空字符串 "" 禁用)
  },

  -- fzf-lua configuration
  fzf_opts = {
    preview = {
      border = 'sharp',
      title = 'Preview',
      wrap = 'wrap',
    },
    winopts = {
      height = 0.8,              -- Window height ratio
      width = 0.8,               -- Window width ratio
      backdrop = 60,             -- Background transparency
    }
  },

  -- Directory search configuration
  directory_search = {
    directories = {
      -- Add your custom directories here
      -- Example:
      -- screenshots = {
      --   path = vim.fn.expand("~/Desktop"),
      --   extensions = { "png", "jpg", "jpeg" },
      --   description = "Screenshots"
      -- }
    },
    default_extensions = {},  -- Empty means all files
  },

  -- Claude integration configuration
  claude_opts = {
    auto_open_terminal = true,       -- Auto open terminal after sending
    context_lines = 5,               -- Additional context lines
    source_tag = "claude-fzf",       -- Source tag
  },
})

键位映射配置

重要说明：插件默认不会设置任何键位映射，避免占用用户的按键。你需要主动配置才能启用键位映射。

方法一：在 setup() 中配置

require('claude-fzf').setup({
  keymaps = {
    files = "<leader>cf",         -- 启用文件选择器键位映射
    grep = "<leader>cg",          -- 启用搜索选择器键位映射
    buffers = "<leader>cb",       -- 启用缓冲区选择器键位映射
    git_files = "<leader>cgf",    -- 启用Git文件选择器键位映射
    directory_files = "<leader>cd", -- 启用目录文件选择器键位映射
  },
})

方法二：使用 lazy.nvim 的 keys 配置

{
  "pittcat/claude-fzf.nvim",
  keys = {
    { "<leader>cf", "<cmd>ClaudeFzfFiles<cr>", desc = "Claude: Add files" },
    { "<leader>cg", "<cmd>ClaudeFzfGrep<cr>", desc = "Claude: Search and add" },
    { "<leader>cb", "<cmd>ClaudeFzfBuffers<cr>", desc = "Claude: Add buffers" },
    { "<leader>cgf", "<cmd>ClaudeFzfGitFiles<cr>", desc = "Claude: Add Git files" },
    { "<leader>cd", "<cmd>ClaudeFzfDirectory<cr>", desc = "Claude: Add directory files" },
  },
}

方法三：手动映射

vim.keymap.set('n', '<leader>cf', ':ClaudeFzfFiles<CR>', { desc = 'Claude: Add files' })
vim.keymap.set('n', '<leader>cg', ':ClaudeFzfGrep<CR>', { desc = 'Claude: Search and add' })
vim.keymap.set('n', '<leader>cb', ':ClaudeFzfBuffers<CR>', { desc = 'Claude: Add buffers' })
vim.keymap.set('n', '<leader>cgf', ':ClaudeFzfGitFiles<CR>', { desc = 'Claude: Add Git files' })
vim.keymap.set('n', '<leader>cd', ':ClaudeFzfDirectory<CR>', { desc = 'Claude: Add directory files' })

📂 Directory Files Feature

The directory files picker allows you to quickly search and select files from your configured directories with optional file type filtering.

Configuration Required

The directory files picker is completely user-configurable. No directories are predefined - you must configure the directories you want to use in your setup.

Usage Examples

Configure directories first, then use:

:ClaudeFzfDirectory                 " Shows configured directory selector

Keyboard shortcut:

<leader>cd                          " Open directory picker

Programmatic usage:

-- Show directory selector (only works if directories are configured)
require('claude-fzf').directory_files()

-- Direct access to specific directory (if configured)
require('claude-fzf').directory_files({ directory = 'screenshots' })

Custom Directory Configuration

Add your own directories in the configuration:

require('claude-fzf').setup({
  directory_search = {
    directories = {
      -- Add your custom directories
      screenshots = {
        path = vim.fn.expand("~/Desktop"),
        extensions = { "png", "jpg", "jpeg" },
        description = "Screenshots"
      },
      my_configs = {
        path = vim.fn.expand("~/.config"),
        extensions = { "lua", "vim", "json", "yaml" },
        description = "Config Files"
      },
      project_docs = {
        path = vim.fn.expand("~/Projects/docs"),
        extensions = { "md", "txt", "rst" },
        description = "Project Documentation"
      }
    }
  }
})

Directory Picker Workflow

Directory Selection: First, choose from available directories
File Filtering: Files are automatically filtered by configured extensions
Multi-selection: Use Tab to select multiple files
Send to Claude: Press Enter to send selected files

Features

✅ Smart Path Validation: Checks if directories exist before searching
✅ Extension Filtering: Only show files matching configured extensions
✅ Performance Optimized: Uses fd command for fast file discovery
✅ Visual Status: Directory availability shown with ✓/✗ indicators
✅ Unicode Support: Properly handles Unicode filenames and paths

🎯 Advanced Usage

Custom Actions

local claude_fzf = require('claude-fzf')

-- Custom file picker
claude_fzf.files({
  prompt = 'Select config files> ',
  cwd = '~/.config',
  fzf_opts = {
    ['--header'] = 'Select config files to add to Claude'
  }
})

Notification Customization

-- Disable all notifications
require('claude-fzf').setup({
  notifications = {
    enabled = false,
  },
})

-- Only show errors, disable success and progress
require('claude-fzf').setup({
  notifications = {
    enabled = true,
    show_progress = false,
    show_success = false,
    show_errors = true,
    use_snacks = true,
  },
})

-- Use snacks.nvim with custom timeout
require('claude-fzf').setup({
  notifications = {
    enabled = true,
    use_snacks = true,
    timeout = 5000,  -- 5 seconds
  },
})

Programmatic Usage

local actions = require('claude-fzf.actions')

-- Send file list directly to Claude
local files = {'src/main.lua', 'src/config.lua'}
actions.send_to_claude(files, { with_context = true })

🐛 Troubleshooting

Common Issues

Q: "fzf-lua not found" error A: Please ensure fzf-lua plugin is installed and properly configured

Q: "claudecode.nvim not found" error A: Please ensure claudecode.nvim plugin is installed and properly configured

Q: Smart context not working A: Please ensure nvim-treesitter is installed with parsers for current file type

Q: Keymap conflicts A: Customize keymaps in configuration or set to empty string to disable

Debugging and Logging

Plugin includes complete logging system for debugging issues:

:ClaudeFzfDebug trace     " Enable detailed trace logging

View logs:

:ClaudeFzfDebug log       " Open log file
:ClaudeFzfDebug stats     " Show log statistics

Configure logging options:

require('claude-fzf').setup({

    show_caller = true,        -- Show caller location
    timestamp = true,          -- Show timestamps
  },
})

Log file location:

Default path: ~/.local/state/nvim/log/claude-fzf.log
