Original issue: barrettruth/diffs.nvim#410
Original author: micampe
Original date: 2026-06-14T09:05:29Z

Prerequisites

I have searched existing issues
I have updated to the latest version

Neovim version

0.12.3

Operating system

macOS 15

Description

Steps to reproduce

set diff.mnemonicPrefix to true in git config
in a repository with some changes and untracked files, run :Diff review
run :copen

Both the diff and the quickfix list only show the untracked files, modified files are missing.

Use this init.lua for easy repro; :Diff1 review sets mnemonicPrefix to show the bug even if it's not set in the global git config.

vim.pack.add({"https://github.com/barrettruth/diffs.nvim"})

vim.api.nvim_create_user_command('Diff1', function (args)
    vim.env.GIT_CONFIG_COUNT = '1'
    vim.env.GIT_CONFIG_KEY_0 = 'diff.mnemonicPrefix'
    vim.env.GIT_CONFIG_VALUE_0 = 'true'
    vim.cmd.Diff(args.fargs)
end, {nargs = '*'})
