Our command :bufdo %s/pizza/donut/g | update looks similar to :cfdo %s/pizza/donut/g | update. This is only possible if we have -m in FZF_DEFAULT_OPTS. To select multiple files, use Tab / Shift+Tab. Select all files you want to perform search and replace on.We can clear it with %bd | e# | bd# (or restart Vim). Our buffers list should contain only the needed files. Here we can choose which files we want to perform select and replace. The second method is to search and replace in select multiple files instead of all files using buffers. The second command, update, saves each file after the first is finished. The first command we are executing is pizza-donut substitution: %s/pizza/donut/g. To run multiple commands, we can chain it with pipe ( |). :cfdo executes any command we pass (in this case, our command is %s/pizza/donut/g) on all entries in our quickfix list. We run :cfdo because :grep uses quickfix. By the way, this would still work even if we didn't reassign ripgrep to replace default grep. :grep pizza uses ripgrep to succinctly search for all instances of "pizza".Let's say you want to replace all instance of "pizza" with "donut". The first method is to replace ALL matching phrases in our project. I will show you two different tricks to easily do search and replace phrases across multiple files in Vim. If I may confess, in the beginning when I had to search/replace string in multiple files, I used VSCode because doing it in Vim, although possible, takes too long. # Search and replace in multiple files Modern text editors like VSCode makes it very easy to search and replace string across multiple files. The answer to "why do we need grep in Vim?" is that it will let us to do what I'll going to cover next: search and replace in multiple files. You might wonder, "Well, this is nice but I never used :grep in Vim, plus can't we just use :Rg to find string in files? When will I ever need to use :grep?" We can use :copen to display quickfix window and :cclose to close quickfix window. I won't go over quickfix here because it's outside this article's scope. Vim :grep command uses quickfix to display results. I can now run a more succinct command :grep "iggy" instead of :grep "iggy". For more information what the options above mean, check out man rg. Now when we run :grep inside Vim, it will run rg -vimgrep -smart-case -follow instead. We can tell Vim to use ripgrep instead of grep by adding this inside our vimrc: set grepprg=rg\ -vimgrep\ -smart-case\ -follow Vim allows us to change the program used by :grep. The command above will search for string "iggy" recursively ( -R) from current location (. R (you may notice that Vim's :grep syntax is similar to terminal grep command this is because :grep by default runs grep -n $* /dev/null on unix-based machine). :vimgrep uses vim's built-in grep and :grep uses external tool which you can reassign using 'grepprg'.įor example, if we want to search for "iggy" with :grep, we can run :grep "iggy". Internally, Vim has two ways to search in files: :vimgrep and :grep. Here's what my FZF mappings look like: " PLUGIN: FZF Other searchesįZF.vim provides many other search commands. With the above, every time we invoke Rg, FZF + ripgrep will not consider filename as a match in Vim. The second line ensures that we have latest FZF. We will be using FZF.vim plugin (created by the same FZF author). To set up FZF in Vim, add these inside your. I am using vim-plug plugin manager in this example, but you can use anything. To learn more, check out fzf's repo or man fzf.Īt minimum we should have export FZF_DEFAULT_COMMAND='rg'.Īfter installing fzf and rg, let's set up Vim. It will come in handy when you want to perform search and replace in multiple files - which I'll cover in just a little bit :). You don't have to use it, but I think it is helpful to be able to select multiple files. This option allows us to make multiple selections (with Tab or Shift-Tab). bashrc if you use bash), I have these: if type rg &> /dev/null thenĮxport FZF_DEFAULT_OPTS='-m -height 50% -border'įZF does not use ripgrep by default, so we need to tell FZF to use ripgrep with FZF_DEFAULT_COMMAND variable. The commands `fzf` and `rg` should be now available. If you have `homebrew`, you can run `brew install fzf` and `brew install ripgrep`. Follow the instruction on their github repo. □ □ □ # Setup Before we start, we need to download () and (). Warning: when using FZF, please fasten your seatbelt, because it can get REALLY fast. In this article, I will show you how to use FZF.vim to make searching in Vim as easy as searching in modern editors/IDEs. One thing that modern text editors/ IDEs got right that Vim didn't is how easy it is to find files and to find in files with modern editors/IDEs.
