rnvimr VS telescope.nvim

You can ranger inside of Neovim with this plugin rnvimr. Check it out. Neo-tree is another plugin that I like as a file manager. And also mini.files is another option if you prefer a more minimal approach and the ability to manipulate files like you edit a normal Neovim buffer. I'm pretty sure there are other great options out there as well, these are just my personal preferences.

https://github.com/kevinhwang91/rnvimr is pretty good, it opens ranger in a floating terminal and takes care of file renaming and deletion, etc.

Ranger inside Neovim for when I need it

This plugin is unique from the other alternatives such as ranger.vim and rnvimr in that my plugin has no dependencies besides ‘ranger’ and written in 100% lua.

chadtree for dealing with files in the current project & Rnvimr (which basically integrates Ranger) when I want to work with files all over the disk.

Although Ranger is a terminal application, you can use it in neovim via some plugins like rnvimr.

If you don't mind switch to another plugin I highly recommend rnvimr to use ranger, a real-world, feature-complete file amanger perfecrly integrated in nvim.

for telescope.nvim (optional) live grep: ripgrep find files: fd

Here we have a configuration for telescope.nvim, a very popular fuzzy finder.

EDIT: I found what I was looking for https://github.com/nvim-telescope/telescope.nvim and https://github.com/nvim-telescope/telescope-file-browser.nvim

Fuzzy Finder: fzf.vim (for its speed) along with telescope.nvim (for its ecosystem)

Just landed on Telescope.nvim: https://github.com/nvim-telescope/telescope.nvim/pull/2572

This extension allows you to use the power of ast-grep to find code patterns in your editor, using the familiar and awesome interface of telescope.nvim.

telescope.nvim

My solution is using telescope.nvim with lsp extension, and map the vim.lsp.buf.definition keybinding to telescope one https://github.com/nvim-telescope/telescope.nvim
