tag - Tag your ag and ripgrep matches


tag is a lightweight wrapper around ag and ripgrep that generates shell aliases for your search matches. tag is a very fast Golang reimagining of sack.

tag supports ag and ripgrep (rg). There are no plans to support ack or grep. If you'd like to add support for more search backends, I encourage you to contribute!

Why should I use tag?

tag makes it easy to immediately jump to a search match in your favorite editor. It eliminates the tedious task of typing vim foo/bar/baz.qux +42 to jump to a match by automatically generating these commands for you as shell aliases.

Inside vim, vim-grepper or ag.vim is probably the way to go. Outside vim (or inside a Neovim :terminal), tag is your best friend.

Finally, tag is unobtrusive. It should behave exactly like ag or ripgrep under most circumstances.

Performance Benchmarks

tag processes ag's output on-the-fly with Golang using pipes so the performance loss is neglible. In other words, tag is just as fast as ag!

$ cd ~/github/torvalds/linux
$ time ( for _ in {1..10}; do  ag EXPORT_SYMBOL_GPL >/dev/null 2>&1; done )
16.66s user 16.54s system 347% cpu 9.562 total
$ time ( for _ in {1..10}; do tag EXPORT_SYMBOL_GPL >/dev/null 2>&1; done )

  1. Update to the latest versions of ag or ripgrep. ag in particular must be version >= 0.25.0.

  2. Install the tag binary using one of the following methods.

  3. By default, tag uses ag as its search backend. To use ripgrep instead, set the environment variable TAG_SEARCH_PROG=rg. (To persist this setting, put it in your bashrc/zshrc.)

  4. Since tag generates a file with command aliases for your shell, you'll have to drop the following in your bashrc/zshrc to actually pick up those aliases.

    • bash

      if hash ag 2>/dev/null; then
        export TAG_SEARCH_PROG=ag  # replace with rg for ripgrep
        tag() { command tag "$@"; source ${TAG_ALIAS_FILE:-/tmp/tag_aliases} 2>/dev/null; }
        alias ag=tag  # replace with rg for ripgrep
    • zsh

      if (( $+commands[tag] )); then
        export TAG_SEARCH_PROG=ag  # replace with rg for ripgrep
        tag() { command tag "$@"; source ${TAG_ALIAS_FILE:-/tmp/tag_aliases} 2>/dev/null }
        alias ag=tag  # replace with rg for ripgrep
    • fish - ~/.config/fish/functions/

      function tag
          set -x TAG_SEARCH_PROG ag  # replace with rg for ripgrep
          set -q TAG_ALIAS_FILE; or set -l TAG_ALIAS_FILE /tmp/tag_aliases
          command tag $argv; and source $TAG_ALIAS_FILE ^/dev/null
          alias ag tag  # replace with rg for ripgrep


tag exposes the following configuration options via environment variables:

    • Determines whether to use ag or ripgrep as the search backend. Must be one of ag or rg.
    • Default: ag
    • Path where shortcut alias file will be generated.
    • Default: /tmp/tag_aliases
    • Prefix for alias commands, e.g. the e in generated alias e42.
    • Default: e
    • Format string for alias commands. Must contain {{.Filename}}, {{.LineNumber}}, and {{.ColumnNumber}} for proper substitution.
    • Default: vim -c 'call cursor({{.LineNumber}}, {{.ColumnNumber}})' '{{.Filename}}'






Instantly jump to your ag or ripgrep matches.
