Question 1

telescope.nvim vs fzf-lua: which should I use?

Accepted Answer

Telescope.nvim is deeply integrated with Neovim's Lua ecosystem, offering more built-in pickers and customization, while fzf-lua wraps the external fzf tool for potentially faster searches but less native integration. Choose Telescope for extensibility within Neovim, or fzf-lua if you prefer fzf's algorithm and have it installed.

Question 2

How to set up telescope.nvim to ignore certain files in searches?

Accepted Answer

Customize the 'file_ignore_patterns' option in your configuration. For example, in setup(): defaults = { file_ignore_patterns = { 'node_modules', '.git' } }. This applies to find_files and similar pickers, as per the README's customization section.

Question 3

Why is my telescope.nvim preview window not showing syntax highlighting?

Accepted Answer

Telescope uses vim.filetype for detection and may require treesitter or syntax plugins. Check the Previewers section in the README; you can use autocmds like 'TelescopePreviewerLoaded' to adjust settings like filetype detection or wrapping.

Question 4

How do I map a custom key to open telescope find files?

Accepted Answer

Use vim.keymap.set in Lua: vim.keymap.set('n', '<leader>ff', require('telescope.builtin').find_files, {}). Refer to the Usage section in the README for more examples, including desc for descriptions.

Question 5

telescope.nvim slow with live_grep, how to speed it up?

Accepted Answer

Install ripgrep and the telescope-fzf-native extension. Ripgrep is required for live_grep, and the native sorter improves sorting performance. Also, ensure your .gitignore is configured to limit search scope.

Question 6

Can I use telescope.nvim without installing ripgrep?

Accepted Answer

Yes, but live_grep and grep_string pickers won't work, as they depend on ripgrep. find_files can use fd or fallback methods, but functionality is limited, so it's strongly recommended in the README.

Question 7

Best way to install telescope.nvim with lazy.nvim?

Accepted Answer

Use a spec like: { 'nvim-telescope/telescope.nvim', version = '*', dependencies = { 'nvim-lua/plenary.nvim' } }. Add telescope-fzf-native as an optional dependency for better performance, as shown in the README's Installation section.
