Show git diff for Git Rebase Interactive

auto-git-diff is a vim plugin which shows git diff between each commit and its parent commit below the commit list window of git rebase interactive.

When you move a text-cursor in git-rebase-todo file, auto-git-diff gets a commit hash of the line where the cursor exists and update the diff window.

Variables

• g:auto_git_diff_disable_auto_update

If this variable is set to 1, the diff window won't update automatically. You can update the diff window manually with the following key mapping: <Plug>(auto_git_diff_manual_update).

• g:auto_git_diff_show_window_at_right

If this variable is set to 1, the diff window will be created at right on the commit list window.

• g:auto_git_diff_command_options

The options passed to git diff command. If this variable is not defined, --stat -p --submodule -C -C will be used.

Mappings

• <Plug>(auto_git_diff_manual_update)

This key mapping updates the diff window manully.

• <Plug>(auto_git_diff_scroll_down_1)
• <Plug>(auto_git_diff_scroll_up_1)
• <Plug>(auto_git_diff_scroll_down_half)
• <Plug>(auto_git_diff_scroll_up_half)
• <Plug>(auto_git_diff_scroll_down_page)
• <Plug>(auto_git_diff_scroll_up_page)

These key mappings scroll the diff window without moving the cursor into the window. _1 means scrolling one line (<C-e> or <C-y>), _half means scrolling half a page (<C-d> or <C-u>) and _page means scrolling one page (<C-f> or <C-b>).

Following is an example to configure the mappings in your vimrc.

function! s:setup_auto_git_diff() abort
    nmap <buffer><C-l> <Plug>(auto_git_diff_scroll_manual_update)
    nmap <buffer><C-n> <Plug>(auto_git_diff_scroll_down_half)
    nmap <buffer><C-p> <Plug>(auto_git_diff_scroll_up_half)
endfunction
autocmd FileType gitrebase call <SID>setup_auto_git_diff()
