# `MingaEditor.State.Git`
[🔗](https://github.com/jsmestad/minga/blob/main/lib/minga_editor/state/git.ex#L1)

Correlation state for editor-level Git workflows and diff presentation.

Repository services own Git data. This value remembers only operations and
generated-buffer views whose results are still relevant to this editor.

# `diff_view_info`

```elixir
@type diff_view_info() :: %{
  :source_buf => pid() | nil,
  :git_root => String.t(),
  :rel_path => String.t(),
  :staged => boolean(),
  :line_metadata => [Minga.Core.DiffView.line_meta()],
  :hunk_lines => [non_neg_integer()],
  optional(:view_mode) => :unified | :side_by_side,
  optional(:pane_width) => pos_integer()

# `register_diff_view`

```elixir
@spec register_diff_view(t(), pid(), diff_view_info()) :: t()
```

Registers a generated diff buffer and its source content.

# `retire_buffer`
