Vim is almost broken for me without fzf+rg. Feels like I’m manually grinding coffee instead of using electricity.

This comment got me to get out my French press and manually grind some beans. It wasn't a meditative and calming as I remember, and the coffee tastes a little...dusty. I guess it's time for me to update my vimrc.

Aeropress is a direct upgrade from french press and uses way less coffee

It's fast indeed. And I can't help keeping promoting the combination with fzf :) For those who want to try it out, this is a Powershell function but the same principle applies in any shell.

I wrote a bash version of this:

  function frg {
    result=`rg --ignore-case --color=always --line-number --no-heading "$@" |
      fzf --ansi \
          --color 'hl:-1:underline,hl+:-1:underline:reverse' \
          --delimiter ':' \
          --preview "bat --color=always {1} --theme='Solarized (light)' --highlight-line {2}" \
          --preview-window 'up,60%,border-bottom,+{2}+3/3,~3'`
    file="${result%%:*}"
    linenumber=`echo "${result}" | cut -d: -f2`
    if [ ! -z "$file" ]; then
            $EDITOR +"${linenumber}" "$file"
    fi
  }

With fzf you can add lots of files to git while skipping some if you want:

    fza = "!git ls-files -m -o --exclude-standard | fzf -m --print0 | xargs -0 git add"

With that in the [alias] section of a gitconfig file, running git fza brings up a list of modified and not yet added files, space toggles each entry and moves to the next entry.

That alias as well as fzf+fd really speed up some parts of my workflow.

Oh and shameless plug for my guide on what to include in your zsh setup on macOS: https://gist.github.com/aclarknexient/0ffcb98aa262c585c49d4b...

What are the reasons for grep not being replaced/improved? This topic seems a bit old by now.

For the same reason the 40yo chair I currently sit in is not being replaced with Razer UltraSeat XR3000-A. It's comfortable, fits the workplace around it, and there's no reason for getting a replacement and rebuilding everything. (Partially because a Razer-like chair already stands nearby taking care of my clothes, but that's where the analogy ends.)

I use ripgrep with the Emacs packages project.el (comes out of the box) and dumb-jump (needs to be installed). This may not be the most popular way of using rg but I have been very pleased with the overall experience. All it takes is running package-install to install the dumb-jump package and configuring the following hook: (add-hook 'xref-backend-functions #'dumb-jump-xref-activate) The Xref key sequences and comma…

Author of ripgrep here. Looking at your regex---just by inspection, I haven't tried it, so I could be wrong---but I think you can drop the --pcre2 flag. I also think you can drop the second and third \b assertion. You might need the first one though.

The example I have posted in my comment is not a command I am typing myself. The dumb-jump package generates this command for us automatically. It is possible to customize the command it generates though. Indeed while running ripgrep manually, I do not use the --pcre2 option. Thank you for developing and maintaining this excellent tool!

One thing I wish ripgrep had is support for AND conditions.

If you don't mind using PCRE, you can do it. For example:

    rg -P '(?=.*pat1)(?=.*pat2)(?=.*pat3)'

You could create a shell function shortcut if you need to use it often. But yeah, having it as a feature of the tool itself would be nice.

Oh. Thanks for the tip. This might make me finally embrace powershell. I’ve been using WSL+zsh+fzf as a Windows CLI for continuity with day job Mac tools, but git CLI performance is only usable inside the WSL file system.

Oooo gotya! That makes more sense. Thanks for the clarification.

Complete guess: it works just fine for 99.9999% of users, but greater than (1-0.999999)% chance that it would break compatibility or have a bug. Anyone who would need the performance gain would know about specialized alternatives.
