Diffview Extra

git.diffview adds diffview-plus.nvim for reviewing file changes, branch diffs, and file history in a dedicated interface. It is the maintained fork of sindrets/diffview.nvim, which has had no commits since June 2024; commands and the diffview module are unchanged, so Neogit’s diffview integration keeps working. Blak follows its tagged releases.

Enable it

-- ~/.config/blak/lua/blak/user.lua
return {
  extras = {
    enabled = {
      "git.diffview",
    },
  },
}

Because this extra adds a plugin, run:

:BlakExtras sync

What it adds

Surface	Contribution
Plugin	dlyongemallo/diffview-plus.nvim (tagged releases)
Dependency	mini.icons for file icons
Command	:DiffviewOpen, :DiffviewClose, :DiffviewToggle
Command	:DiffviewFileHistory, :DiffviewDiffFiles, :DiffviewLog
Keymap	<leader>gD opens Diffview
Keymap	<leader>gH opens file history for the current file

The keymaps appear in :BlakKeys.

Common workflows

Open the current working tree diff:

:DiffviewOpen

Compare the current branch to main:

:DiffviewOpen main...HEAD

Inspect the current file’s history:

<leader>gH

user.lua configuration

The Blak extra intentionally keeps Diffview’s plugin options at their defaults. Your user.lua only needs to opt into the extra:

return {
  extras = {
    enabled = { "git.diffview" },
  },
}

To change Diffview options, add a matching lazy.nvim spec in plugins.specs; lazy.nvim merges it with the extra’s spec:

return {
  extras = { enabled = { "git.diffview" } },
  plugins = {
    specs = {
      { "dlyongemallo/diffview-plus.nvim", opts = { enhanced_diff_hl = true } },
    },
  },
}

Disable it

:BlakExtras disable git.diffview
:BlakExtras sync
