Prerequisites

First you need to install fzf via vim-plug:

call plug#begin()

" if you have fzf installed via brew
if isdirectory('/usr/local/opt/fzf')
    Plug '/usr/local/opt/fzf'
else
    Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }
endif
Plug 'junegunn/fzf.vim', {
        \ 'on': [
            \ 'Ag',
            \ 'Rg',
            \ 'FZF',
            \ 'Files',
            \ 'Buffers',
            \ 'Commits',
            \ 'BCommits',
            \ 'Tags',
            \ 'BTags',
            \ 'History',
            \ 'Lines',
            \ 'BLines',
            \ 'Marks'
        \ ] }

call plug#end()

Configuring Meta key (⌥) in macOS terminal

Some shortcuts use Meta key. To make it work properly in macOS terminal check the «Use option as meta key»:

Or «Esc+» option in iterm2:

Finding and replacing text

To search text within project files simply type :Rg <text>. This will open up a FZF buffer with a list of files.

Then with a Tab key you can select/deselect files that you want to pass to quickfix window. To select all files tap Alt/⌥-a and to deselect Alt/⌥-d.

Once your selection is ready hit Enter to pass selected files to quickfix buffer.

Now you can replace text in all files within quickfix buffer with :cfdo %s/<text to search>/<text to replace with>/g | update.

The cfdo command simply executes command on every file in the list, and the update command after the pipe saves the results to the disk.

I've used here some of the snippets from my vim setup. You can find it here:

gko / vimio
