Open remote git repositories in the comfort of Neovim.

A plugin to open remote Git repositories inside Neovim by managing ephemeral shallow clones automatically. It aims to provide a similar experience to GitHub.dev but directly within Neovim.

:blue_book: Usage

:open_file_folder: Open

API: require("git-dev").open(repo, ref, opts)

Command: GitDevOpen

Open the repository in Neovim.

Parameters

Examples

-- :GitDevOpen moyiz/git-dev.nvim
require("git-dev").open("moyiz/git-dev.nvim")

-- :GitDevOpen derailed/k9s '{ tag = "v0.32.4" }'
require("git-dev").open("derailed/k9s", { tag = "v0.32.4" })

-- :GitDevOpen echasnovski/mini.nvim '{ branch = "stable" }' '{ ephemeral = false }'
require("git-dev").open("echasnovski/mini.nvim", { branch = "stable "}, { ephemeral = false })

-- :GitDevOpen https://git.savannah.gnu.org/git/bash.git '{}' '{ read_only = false }'
require("git-dev").open("https://git.savannah.gnu.org/git/bash.git", {}, { read_only = false })

:broom: Clean All

API: require("git-dev").clean_all()

Command: GitDevCleanAll

Clean all cached local repositories.

Caution: It will delete the repositories directory itself. If you changed the default value, make sure that the new directory is being used only for this purpose.

By either using the lua function require("git-dev").clean_all() or the command GitDevCleanAll.

:eyeglasses: Parse

API: require("git-dev").parse(repo, opts)

Parses a Git URL.

Parameters

See URL Parsing.

:goggles: Toggle UI

API: require("git-dev").toggle_ui(win_config)

Command: GitDevToggleUI

Manually toggle the window showing git-dev output. Accepts optional table to override default window configuration.

Parameters

:telescope: Telescope

:bone: Recent Repositories

Command: GitDevRecents

Revisit previously opened repositories via a telescope extension.

Opened repositories are tracked in a simple single file KV store. Its only purpose (currently) is to be queried by the telescope extension for a convenient way to re-open previously opened repositories. See history in Options below.

:spider_web: URL Parsing

It is reasonable to assume that browsing arbitrary Git repositories will probably begin in a web browser. The main purpose of this feature is to allow quicker transition from the currently viewed branch / tag / commit / file to Neovim.

This plugin supports multiple types and flavors of URLs. It will accept most GitHub, GitLab, Gitea and Codeberg URLs, and will try to extract the actual git repository URL, selected branch / tag / commit and selected file.

If such extraction was successful, opener will be provided with selected_path, which is a relative path of a file in the repository. Its main use-case is to auto-open currently viewed file.

Nested branches (contain slashes) are supported.

Notice that passing explicit ref to GitDevOpen will take precedence on parsed fields.

Supported URLs

Examples

Open README.md in main branch:

require("git-dev").open("https://github.com/echasnovski/mini.nvim/blob/main/README.md")

Parser output:

{
  branch = "main",
  repo_url = "https://github.com/echasnovski/mini.nvim.git",
  selected_path = "README.md",
  type = "http"
}

Open cmd/scan/main.go in acook/generic_docker_source_entry branch:

require("git-dev").open("https://gitlab.com/gitlab-org/code-creation/repository-x-ray/-/blob/acook/generic_docker_source_entry/cmd/scan/main.go")

Parser output:

{
  branch = "acook/generic_docker_source_entry",
  repo_url = "https://gitlab.com/gitlab-org/code-creation/repository-x-ray.git",
  selected_path = "cmd/scan/main.go",
  type = "http"
}

See lua/git-dev/parser_spec.lua for more examples.

Limitations

Notice this feature is quite experimental. If you encounter any issues or have any questions or requests, feel free to reach out.

:notebook: Recipes

:grey_question: Interactive Opening

The sky is the limit. I have settled for this key binding at the moment (set via lazy.nvim):

{
  "moyiz/git-dev.nvim",
  ...
  keys = {
    {
      "<leader>go",
      function()
        local repo = vim.fn.input "Repository name / URI: "
        if repo ~= "" then
          require("git-dev").open(repo)
        end
      end,
      desc = "[O]pen a remote git repository",
    }
  }
  ...
}

:evergreen_tree: nvim-tree

To open with nvim-tree:

opts = {
  opener = function(dir, _, selected_path)
    -- vim.cmd("Oil " .. vim.fn.fnameescape(dir))
    vim.cmd("NvimTreeOpen " .. vim.fn.fnameescape(dir))
    if selected_path then
      vim.cmd("edit " .. selected_path)
    end
  end
}

:evergreen_tree: neo-tree

opts = {
  opener = function(dir, _, selected_path)
    vim.cmd("Neotree " .. dir)
    if selected_path then
      vim.cmd("edit " .. selected_path)
    end
  end
}

:bookmark_tabs: New tab

Recommended. Repositories will be opened in a new tab and its CWD will be set.

opts = {
  cd_type = "tab",
  opener = function(dir, _, selected_path)
    vim.cmd "tabnew"
    vim.cmd("Neotree " .. dir)
    if selected_path then
      vim.cmd("edit " .. selected_path)
    end
  end
}

:fox_face: Web browser

It does not make much sense on its own, but a showcase for getting both the repository URL and the local directory.

opts = {
  cd_type = "none",
  opener = function(_, repo_url)
     -- vim.cmd("!librewolf " .. repo_url)
     vim.cmd("!firefox " .. repo_url)
  end
}

:pencil: Customizing Default URL

By default, this plugin accepts partial repository URI (e.g. org/repo) by applying it onto a format string. This behavior can be customized by setting git.base_uri_format to change the URI, or git.default_org to prepend a default organization name if the given repository name does not contain /.

-- Change default URI
opts = {
  git = {
    base_uri_format = "https://git.home.arpa/%s.git",
  }
}

-- Open my own repositories by name with SSH.
-- E.g. "git-dev.nvim" rather than "moyiz/git-dev.nvim"
opts = {
  git = {
    default_org = "moyiz",
    base_uri_format = "git@github.com:%s.git",
  }
}

-- Enforce only full URIs (do not accept partial names).
opts = {
  git = {
    base_uri_format = "%s"
  }
}

:house_with_garden: Private Repositories - Parse HTTP as SSH

All repositories in my home Gitea service are private. Cloning such repositories using HTTP URLs will require inserting user and password. Since my SSH keys are already set, a custom parser can workaround it by leveraging the domain parameter of the parser function.

opts = {
  extra_domain_to_parser = {
    ["git.home.arpa"] = function(parser, text, _)
      text = text:gsub("https://([^/]+)/(.*)$", "ssh://git@%1:2222/%2")
      return parser:parse_gitea_like_url(text, "ssh://git@git.home.arpa:2222")
    end,
  },
}

Notice that my Gitea service listens on port 2222 for SSH. This custom parser tricks parse_gitea_like_url by converting a HTTP URL to SSH like URL (which is not a valid git URI). I.e.

https://git.home.arpa/homelab/k8s/src/commit/ef3fec4973042f0e0357a136d927fe2839350170/apps/gitea/kustomization.yaml

To:

ssh://git@git.home.arpa:2222/homelab/k8s/src/commit/ef3fec4973042f0e0357a136d927fe2839350170/apps/gitea/kustomization.yaml

Then, the parser trims the "domain" and proceeds as usual. Output:

{
  commit = "ef3fec4973042f0e0357a136d927fe2839350170",
  repo_url = "ssh://git@git.home.arpa:2222/homelab/k8s.git",
  selected_path = "apps/gitea/kustomization.yaml",
  type = "http"
}
