🦘 telescope-repo.nvim: jump around the repositories in your filesystem, without any setup

telescope-repo is an extension for telescope.nvim that searches the filesystem for git (or other SCM¹, like Pijul, Mercurial…) repositories. It does not require any setup: the list of repositories is built on the fly over your whole $HOME, you don’t need to manually add projects or open some folders to populate this list, as opposed to telescope-project.nvim or project.nvim.

Use cases include:

• If you don’t start vim from the shell (from a GUI or as the start command of a terminal), you are most likely in your $HOME directory. You then want to jump into your code as quickly as possible and this plugin can help!
• Sometimes, you have the definition of a function and use of it in different repositories (e.g. a library you wrote and a program using this library). This plugin helps to open the two, for instance in two splits.
• Use of less popular SCMs: some similar extensions rely on strong conventions to find repositories, like “directories containing a .git file that is also a directory, all inside directory X”. Less popular SCMs like Pijul have a different folder name, and even git worktrees don’t fit neatly into these constraint, with their .git files.

telescope-repo.nvim is based on telescope-ghq.nvim

Installation

You need to add these in your plugin management system²:

'nvim-lua/plenary.nvim'
'nvim-telescope/telescope.nvim'
'cljoly/telescope-repo.nvim'

And optionally, to load the extension:

require'telescope'.load_extension'repo'

A handy companion plugin is vim-rooter, as it’ll change the current directory according to the current file’s detected project (often, the root of the git repository). To get it to change each buffer’s directory, instead of the whole editor by default, add the following Lua to your configuration:

g['rooter_cd_cmd'] = 'lcd'

Packer

For instance, with Packer.nvim:

use 'cljoly/telescope-repo.nvim'
use {
  'nvim-telescope/telescope.nvim',
  requires = { {'nvim-lua/plenary.nvim'} }
}

External Dependencies

Required

• fd to find the repositories on the filesystem with list
• plocate, lolcate-rs or locate to find the repositories on the filesystem with cached_list

Optional

• glow to preview markdown files, will fall back to bat if not present (and uses cat if neither are present)

Usage

Global Configuration

You can change the default argument given to subcommands (like list or cached_list) using the telescope setup function with a table like this:

{
  extensions = {
    repo = {
      <subcommand> = {
        <argument> = {
          "new",
          "default",
          "value",
        },
      },
      settings = {
        auto_lcd = true,
      }
    },
  },
}

for instance, you could do:

require("telescope").setup {
  extensions = {
    repo = {
      list = {
        fd_opts = {
          "--no-ignore-vcs",
        },
        search_dirs = {
          "~/my_projects",
        },
      },
    },
  },
}

require("telescope").load_extension "repo"

Note: make sure to have require("telescope").load_extension "repo" after the call to require("telescope").setup {…}, otherwise the global configuration won’t be taken into account.

list

:Telescope repo list or lua require'telescope'.extensions.repo.list{}

Running repo list and list repositories' paths.

key	action
<CR>	Cd to selected directory

Options

bin

Filepath for the binary fd.

" path can be expanded
:Telescope repo list bin=~/fd

pattern

Pattern of the SCM database folder.

Default value: [[^\.git$]]

cwd

Transform the result paths into relative ones with this value as the base dir.

Default value: vim.fn.getcwd()

fd_opts

This is a relatively advanced option that you should use with caution. There is no guarantee that a particular set of options would work the same across multiple versions

This passes additional options to the command fd that generates the repository list. It is inserted like so:

fd [set of default options] [fd_opts] --exec [some default command] [pattern] …

Example

Let’s say you have a git repository S inside another git repository M (for instance because of #5), but S is in a directory that’s ignored in the .gitignore in M. S wouldn’t appear in the Telescope list of this extension by default, because it is ignored (.gitignore are taken into account by default).

To avoid taking into account the .gitignore, we need to pass --no-ignore-vcs to fd, like so (in NeoVim):

:lua require'telescope'.extensions.repo.list{fd_opts={'--no-ignore-vcs'}}

This will list M and S in the Telescope output! The downside is that listing repositories will be a little longer, as we don’t skip the git-ignored files anymore.

search_dirs

This limits the search to a particular directory or set of directories.

Example

:lua require'telescope'.extensions.repo.list{search_dirs = {"~/ghq/github.com", "~/ghq/git.sr.ht"}}
:lua require'telescope'.extensions.repo.list{search_dirs = {"~/.local/share/nvim/site/pack"}}

tail_path

Show only basename of the path.

Default value: false

shorten_path

Call pathshorten() for each path. This will for instance transform /home/me/code/project to /h/m/c/project.

Default value: false

Examples

Here is how you can use this plugin with various SCM:

SCM	Command
git	:Telescope repo list or lua require'telescope'.extensions.repo.list{}
pijul	lua require'telescope'.extensions.repo.list{pattern=[[^\.pijul$]]}
hg	lua require'telescope'.extensions.repo.list{pattern=[[^\.hg$]]}
fossil	lua require'telescope'.extensions.repo.list{pattern=[[^\.fslckout$]]}

Is your favorite SCM missing? It should be straightforward to support it by changing the pattern parameter. If you want it to be considered for addition here, open a PR!

cached_list

:Telescope repo cached_list

This relies on a locate command to find repositories. This should be much faster than the list command, as it relies on a pre-built index but results may be stalled.

Note: at this point, the plugin does not manage index update. Updating the index often requires to run a command like updatedb as root.

Notes for MacOS

glocate command used for caching on MacOS comes with gnu findutils which can be installed with

brew install findutils

With glocate installed use, add the following to your .bashrc/.zshrc

# https://egeek.me/2020/04/18/enabling-locate-on-osx/
if which glocate > /dev/null; then
  alias locate="glocate -d $HOME/locatedb"

  # Using cache_list requires `LOCATE_PATH` environment var to exist in session.
  # trouble shoot: `echo $LOCATE_PATH` needs to return db path.
  [[ -f "$HOME/locatedb" ]] && export LOCATE_PATH="$HOME/locatedb"
fi

alias loaddb="gupdatedb --localpaths=$HOME --prunepaths=/Volumes --output=$HOME/locatedb"

After you have run loaddb the first time you need to reload the shell to make sure that it exports the LOCATE_PATH variable. Then the following command should work:

lua require'telescope'.extensions.repo.cached_list()

If nothing is shown, even after a little while, try this:

lua require'telescope'.extensions.repo.cached_list{locate_opts={"-d", vim.env.HOME .. "/locatedb"}}

Note: Installation and use of the plugin on systems other than GNU/Linux is community-maintained. Don't hesitate to open a discussion or a pull-request if something is not working!

Troubleshooting

You should try to run:

sudo updatedb

if you encounter any problems. If it’s not the case by default, you should automate such index update with for instance cron or systemd-timers. See https://wiki.archlinux.org/title/Locate and this discussion for various ways to automate this.

Options

Options are the similar to repo list, bearing in mind that we use locate instead of fd. Note that the following list options are not supported in cached_list:

• fd_opts, as we don’t use fd with cached_list,
• search_dirs, as locate does not accept a directory to search in.

Examples

Exclude Irrelevant Results

Chances are you will get results from folders you don’t care about like .cache or .cargo. In that case, you can use the file_ignore_patterns option of Telescope, like so (these are Lua regexes).

Hide all git repositories that may be in .cache or .cargo:

:lua require'telescope'.extensions.repo.cached_list{file_ignore_patterns={"/%.cache/", "/%.cargo/"}}

Notes

• These patterns are used to filter the output of the locate command, so they don’t speed up the search in any way. You should use them mainly to exclude git repositories you won’t want to jump into, not in the hope to enhance performance.
• The %. in Lua regex is an escaped . as . matches any characters.
• These patterns are applied against whole paths like /home/myuser/.cache/some/dir, so if you want to exclude only /home/myuser/.cache, you need a more complicated pattern like so:

:lua require'telescope'.extensions.repo.cached_list{file_ignore_patterns={"^".. vim.env.HOME .. "/%.cache/", "^".. vim.env.HOME .. "/%.cargo/"}}

Use With Other SCMs

Here is how you can use this plugin with various SCM (we match on the whole path with locate, so patterns differ slightly from repo list: notice the ^ that becomes a /):

SCM	Command
git	:Telescope repo list or lua require'telescope'.extensions.repo.list{}
pijul	lua require'telescope'.extensions.repo.list{pattern=[[/\.pijul$]]}
hg	lua require'telescope'.extensions.repo.list{pattern=[[/\.hg$]]}
fossil	lua require'telescope'.extensions.repo.list{pattern=[[/\.fslckout$]]}

FAQ

No repositories are found

Make sure that :checkhealth telescope shows something like:

## Telescope Extension: `repo`
  - OK: Will use `glow` to preview markdown READMEs
  - OK: Will use `bat` to preview non-markdown READMEs
  - OK: locate: found `plocate`

This may take a few seconds to run

The output of this command may point to missing dependencies.

Getting the repository list is slow

If :Telescope repo list is slow, you can use your .fdignore to exclude some folders from your filesystem. You can even use a custom ignore file with the --ignore-file option, like so:

lua require'telescope'.extensions.repo.list{fd_opts=[[--ignore-file=myignorefile]]}

Contribute

Contributions are welcome, see this document!

The telescope developers documentation is very useful to understand how plugins work and you may find these tips useful as well.

Running tests

Plenary.nvim integration tests are executed as a part of the CI checks. However, they are very basic for now and you might be better off just testing the two commands locally.

Code Formatting & Linting

StyLua is used for code formatting. It is run like so:

make fmt

To run the linter:

make lint

Acknowledgement

I would like to thank all the contributors to this plugin, as well as the developers of neovim and Telescope. Without them, none of this would be possible.

Thanks to Code Smell for demoing the plugin in 5 Terrific Neovim Telescope Extensions for 2022 🔭.

Furthermore, thanks to Migadu for offering a discounted service to support this project. It is not an endorsement by Migadu though.

Stability

We understand that you need a reliable plugin that never breaks. To this end, code changes are first tested on our machines in a separate dev branch and once we are reasonably confident that changes don’t have unintended side-effects, they get merged to the master branch, where a wider user-base will get the changes. We also often tag releases, holding a more mature, coherent set of changes. If you are especially sensitive to changes, instruct your package manager to install the version pointed by a particular tag and watch for new releases on GitHub or via RSS. Conversely, if you wish to live on the bleeding-edge, instruct your package manager to use the dev branch.
