With neoclide/coc-git@43469d259a3d If you have coc-git with git.allChunkInfo use the chuck info to find realtime changes that doesn't require a write.

Post TextChanged,TextChangedI controlled by updatetime wait 500ms and query git.allChunkInfo

Check list

  • I have read through the README (especially F.A.Q section)
  • I have searched through the existing issues or pull requests

📝 Walkthrough

Walkthrough

The plugin polls for CoC Git support, registers conditional text-change events, debounces minimap refreshes by 500 ms, and uses CoC chunk data or shell-based Git diff output for coloring.

Changes

Minimap Git refresh

Layer / File(s) Summary
CoC capability and delayed refresh
autoload/minimap/vim.vim
The plugin detects git.allChunkInfo, registers TextChanged and TextChangedI when available, and schedules delayed minimap and highlight refreshes.
Git diff data source
autoload/minimap/vim.vim
Git coloring requests CoC chunk data when available and falls back to parsing git diff -U0 output when CoC data is unavailable.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to e123d

The change can leave Git colors missing in buffers that are not managed by the configured integration because an empty result prevents the existing fallback from running. Merge should wait for that fallback behavior to be restored or explicitly accepted by the owner.

Keep the shell fallback for buffers that coc-git does not manage.

git.allChunkInfo returns an empty list when the current buffer has no GitBuffer. Fall back when CocAction() fails or returns an empty list.
