📖 Table of contents

✨ Features

  • Colors/icons, Windows and modern Neovim features support.
  • Updates on every keystroke of user query and selection.
  • Multiple variants to avoid manual input:
    • Search by visual select.
    • Search by cursor word.
    • Search by yank text.
    • Search by resume last search.
  • Multiple data sources to avoid restart search flow:
    • Exclude or include hiddens/ignores when searching files.
    • Local or remote when searching git branches.
    • Whole workspace or current buffer only when searching diagnostics.
    • ...
  • And a lot more.

Please see Demo for more use cases.

✅ Requirements

  • Neovim ≥ 0.7.
  • fzf.
  • curl (for query fzf status or update preview label).
  • nerd-fonts (optional for icons).
  • rg (optional for live grep, by default use grep).
  • fd (optional for find files, by default use find).
  • bat (optional for preview files, by default use cat).
  • git (mandatory for git diff, show, blame).
  • delta (optional for preview git diff, show, blame).
  • lsd/eza (optional for file explorer, by default use ls).

For Windows

Windows users will have to install the linux shell environment, since basic linux commands such as echo, mkdir are internally required.

There're many ways to install portable linux shell and builtin commands on Windows, but personally I would recommend below two methods:

Git for Windows

Install with the below 3 options:

  • In Select Components, select Associate .sh files to be run with Bash.

  • In Adjusting your PATH environment, select Use Git and optional Unix tools from the Command Prompt.

  • In Configuring the terminal emulator to use with Git Bash, select Use Windows's default console window.

After this step, git.exe and builtin linux commands(such as echo.exe, ls.exe, curl.exe) will be available in %PATH%.

scoop

Run below powershell commands:

# scoop
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
irm get.scoop.sh | iex

scoop bucket add extras
scoop install git           # git, bash, sh
scoop install uutils-coreutils     # echo, ls, cat
scoop install curl          # curl
scoop install grep          # grep

Note: Install the rust rewritten uutils-coreutils instead of GNU coreutils, some GNU commands (for example ls) is actually broken on Windows 10 x86_64 PC.

Fix conflicts between embedded commands in C:\Windows\System32 and portable linux commands

Windows actually already provide some commands (find.exe, bash.exe) in C:\Windows\System32 (or %SystemRoot%\system32), while they are not the linux commands they are named after, but could override our installations. To fix this issue, we could prioritize the git or scoop environment variables in %PATH%.

📦 Install

[!IMPORTANT]

Specify plugin version/tag (e.g. v5.*) to avoid break changes between major versions!

require("lazy").setup({
  -- optional for icons
  { "nvim-tree/nvim-web-devicons" },

  -- optional for the 'fzf' command
  {
    "junegunn/fzf",
    build = function()
      vim.fn["fzf#install"]()
    end,
  },

  {
    "linrongbin16/fzfx.nvim",
    dependencies = { "nvim-tree/nvim-web-devicons", 'junegunn/fzf' },

    -- specify version to avoid break changes
    version = 'v5.*',

    config = function()
      require("fzfx").setup()
    end,
  },
})
return require("packer").startup(function(use)
  -- optional for icons
  use({ "nvim-tree/nvim-web-devicons" })

  -- optional for the 'fzf' command
  use({
    "junegunn/fzf",
    run = function()
      vim.fn["fzf#install"]()
    end,
  })

  use({
    "linrongbin16/fzfx.nvim",

    -- specify version to avoid break changes
    version = 'v5.0.0',

    config = function()
      require("fzfx").setup()
    end,
  })
end)
call plug#begin()

" optional for icons
Plug 'nvim-tree/nvim-web-devicons'

" optional for the 'fzf' command
Plug 'junegunn/fzf', { 'do': { -> fzf#install() } }

" specify version to avoid break changes
Plug 'linrongbin16/fzfx.nvim', { 'tag': 'v5.0.0' }

call plug#end()

lua require('fzfx').setup()

🚀 Usage

There're multiple commands provided, named with prefix Fzfx. The sub commands indicates the user query's input method, (e.g. the variants) named with below rules:

  • Basic variant is named with args, accepts the following arguments as query content.
  • Visual select variant is named with visual, uses visual selection as query content.
  • Cursor word variant is named with cword, uses the word text under cursor as query content.
  • Put (e.g. yank text) variant is named with put (just like press the p key), uses the yank text as query content.
  • Resume last search variant is named with resume, uses the last search content as query content.

[!NOTE]

The args sub command can be omitted, for example :FzfxFiles<CR> is equivalent to :FzfxFiles args<CR>.

To specify query text, for example asdf, you will have to type :FzfxFiles args asdf<CR>.

Below keys are binded by default:

  • Exit keys (fzf --expect option)
    • esc: quit.
    • double-click/enter: open/jump to file (behave different on some specific commands).
  • Preview keys
    • alt-p: toggle preview.
    • ctrl-f: preview half page down.
    • ctrl-b: preview half page up.
  • Select keys
    • ctrl-e: toggle select.
    • ctrl-a: toggle select all.

🔧 Configuration

To configure options, please use:

require('fzfx').setup(opts)

The opts is an optional lua table that override the default options.

For complete default options, please see config.lua.

For advanced configurations, please check Advanced Configuration.

Feature Flags

To enable/disable some features, please define below global variables before setup this plugin:

  • vim.g.fzfx_disable_buffer_previewer: Disable nvim buffer for previewing file contents, use fzf builtin preview window via bat with best performance.

    " vim scripts
    let g:fzfx_disable_buffer_previewer = 1 " or v:true
    
    -- lua scripts
    vim.g.fzfx_disable_buffer_previewer = 1 -- or true

      fzf_opts = {
        "--multi",
        { "--prompt", "Ls > " },

You can also use the require("fzfx").register("ls", {...}) api to do that.

For detailed explanation of each components, please see A Generic Schema for Creating FZF Command and schema.lua.

API References

To help easier customizing/integrating, fzfx provides below builtin modules and APIs:

  • fzfx.cfg: Top-level configurations, e.g. directly create the FzfxFiles, FzfxLiveGrep, etc search commands. Easy to read and learn all the components used in those commands, as well as easy to copy and paste.

  • fzfx.helper: Line-oriented helper utilities for parsing and rendering user queries and lines, since a search command is actually all about the lines in (both left and right side of) the fzf binary: generate lines, preview lines, invoke callbacks on selected lines, etc.

  • fzfx.lib: Low-level fundamental infrastructures, fzfx use the commons lua library for most of the common utilities, please also refer to commons.nvim's documentation.

    The commons library was originally part of fzfx.lib, since I found they're so commonly used that I almost need them for every of my Neovim plugins, I extracted them from fzfx and build up this library.

Please see API References for more details.
