Usage

This repository exports lua functions for the user to bind to vim commands or keybindings.

Example

noremap <leader>f <cmd>lua require("fzf-commands").files()<cr>
" or
command! Files lua require("fzf-commands").files()
" or with configuration
noremap <leader>f <cmd>lua require("fzf-commands").files({ fzf = custom_fzf_function })<cr>

Commands

These are keys of require("fzf-commands"). For eg.: require('fzf-commands').files()

files(options): Open files in the current vim directory

• List files (using fd if available, otherwise find)
• Preview (using bat if available, otherwise head)
• Supports opening multiple files
• Can open files in the same window, in a [vertical] split, or in a new tab (enter, ctrl-s, ctrl-v, ctrl-t).

helptags(options): Open neovim help files

• Can open files in the same window, in a [vertical] split, or in a new tab (enter, ctrl-s, ctrl-v, ctrl-t).

bufferpicker2(options): Pick between buffers to switch to them or open in a split.

• Preview the buffers (with neovim syntax highlighting!)
• Can handle multiple buffers
• Can open files in the same window, in a [vertical] split, or in a new tab (enter, ctrl-s, ctrl-v, ctrl-t).
• Options:
  • options.height (number): the height of the split
  • options.unloaded (boolean): show unloaded buffers
  • options.unlisted (boolean): show unlisted buffers
  • options.direction (string: "top" / "bottom"): where to display the split.
  • does not take options.fzf, because this function opens two windows, one for fzf, one for the preview.

bufferpicker(options): Pick between buffers to switch to them or open in a split.

• Preview the buffers (plaintext)
• Can handle multiple buffers
• Can open files in the same window, in a [vertical] split, or in a new tab (enter, ctrl-s, ctrl-v, ctrl-t).

manpicker(options): Open a manpage using nvim's Man.

• Can open files in the same window, in a [vertical] split, or in a new tab (enter, ctrl-s, ctrl-v, ctrl-t).

rg(pattern, options): Search for a pattern using rg (ripgrep).

• Can handle opening multiple search results

• Can open files in the same window, in a [vertical] split, or in a new tab (enter, ctrl-s, ctrl-v, ctrl-t).

  Example usage:

  command! -nargs=1 Rg call luaeval('require("fzf-commands").rg(_A)', <f-args>)
  nnoremap <leader>r :<c-u>Rg<space>

colorschemes(options): Pick a vim colorscheme.

• Previews the colorscheme live as you navigate them.

Configuration

All commands support a custom fzf function that manages opening windows and running fzf.

Example changing height and width of default window

This example uses window_options, documentation here

require("fzf-commands").files({ fzf = function(contents, options) 
  return require("fzf").fzf(contents, options, { height = 10, width = 30 })
end })

Other examples

function my_custom_fzf(contents, options)
  vim.cmd("vnew")
  local results = require("fzf").raw_fzf(contents, options)
  vim.cmd("bw!")
  return results
end
require("fzf-commands").files({ fzf = my_custom_fzf })

or

" vertical fzf
lua << EOF
  function my_custom_fzf(contents, options)
    vim.cmd("vnew")
    local results = require("fzf").raw_fzf(contents, options)
    vim.cmd("bw!")
    return results
  end
EOF
command! Files lua require("fzf-commands").files({ fzf = my_custom_fzf })

For other configuration, please see command specific documentation.

Contribution notes

Contributions welcome!

• Any improvements (previews, bindings) to existing commands welcome!
• Any commands relevant to vim or common unix tools welcome!
• Issues welcome for edge cases or need for configurability. Configuration should only be added if the user needs it.
• Commands must be asynchronous at all costs for UI speed reasons.
• A gif demonstrating the command would be appreciated.
• All commands should take an fzf configuration option that provides the fzf command to use instead of the default nvim_fzf.fzf function.
