fzf

fzf is a CLI fuzzy finder with endless possibilities. If you want to improve your terminal workflow you must check this out.

Use cases (at least for me - there are way more):

• fuzzy find any file on your machine
• fuzzy find the shell history
• fuzzy find directories
• open and search files within vim
• search through tags, lines, commits, and windows in vim

fzf.vim

• make ESC work in fzf buffer

  autocmd  FileType fzf tnoremap <Esc> <C-c>
    \| autocmd BufLeave <buffer> tnoremap <Esc> <C-\><C-n>

• Keymappings

  nnoremap <C-p> :Files<CR>
  nnoremap <leader>rg :Rg<CR>
  nnoremap <leader>fr :History<CR>
  nnoremap <leader>w :Windows<CR>
  nnoremap <leader>; :BLines<CR>
  nnoremap <leader>: :BTags<CR>
  nnoremap <leader>c :Commits<CR>
  nnoremap <leader>ft :Filetypes<CR>

• Adjust colortheme

  let g:fzf_colors =
  \ { 'fg':      ['fg', 'Comment'],
  \ 'bg':      ['bg', 'Normal'],
  \ 'hl':      ['fg', 'Comment'],
  \ 'fg+':     ['fg', 'CursorLine', 'CursorColumn', 'Normal'],
  \ 'bg+':     ['bg', 'CursorLine', 'CursorColumn'],
  \ 'hl+':     ['fg', 'Statement'],
  \ 'info':    ['fg', 'String'],
  \ 'border':  ['fg', 'Ignore'],
  \ 'prompt':  ['fg', 'Boolean'],
  \ 'pointer': ['fg', 'Boolean'],
  \ 'marker':  ['fg', 'Keyword'],
  \ 'spinner': ['fg', 'Label'],
  \ 'header':  ['fg', 'Comment'] }

• Adjust layout

  let $FZF_DEFAULT_OPTS .= ' --no-height'
  " disable statusline overwriting
  let g:fzf_nvim_statusline = 0
  " In Neovim, you can set up fzf window using a Vim command
  let g:fzf_layout = { 'window': 'enew' }
  let g:fzf_layout = { 'window': '-tabnew' }
  let g:fzf_layout = { 'window': '10split enew' }

fzf tweaks

• export FZF_COMPLETION_TRIGGER=',,'

  Allows to trigger fzf after arbitrary commands, for instance vim ,, /TAB/ invokes fzf

• export FZF_DEFAULT_OPTS="--bind='ctrl-o:execute:vim {} > /dev/tty'"

  Enables you to directly open a file for fzf results with ctrl-o

• export FZF_CTRL_T_OPTS="--preview '(highlight -O ansi -l {} 2> /dev/null || cat {} || tree -C {}) 2> /dev/null | head -200'"

  Shows a preview of highlighted files in fzf

• export FZF_ALT_C_OPTS="--preview 'tree -C {} | head -200'"

  Directory structure preview of highlighted directories within fzf

• command -v rg >/dev/null 2>&1 && export FZF_DEFAULT_COMMAND='rg --files --no-ignore-vcs --hidden'

  Use ripgrep when it is installed as default
