Add an option so that opening a file from macOS’s "external editor" mechanism does not bring macvim to foreground

In macOS, I am setting the default editor for source code files to open with macvim be default so that macvim can be the editor when debugging on lldb with lldb --editor. However, whenever a breakpoint is hit, or a frame changed, the focus automatically goes from lldb to macvim. I wish I could keep the focus on lldb instead.

Describe the solution you'd like

Maybe there could be an option called macvim_dont_bring_to_foreground, set to 0 by default, that enables the current behavior (bringing macvim to foreground when a remote command arrives), and can be set to 1 to disable the foreward bringing).

Describe alternatives you've considered

I have considered using vim in the terminal instead, by the server part of +clientserver is disabled.

EDIT: lldb don’t use $EDITOR but the host’s external editor instead.

まず、MacVim の macOS における external-editor または remote-command の処理と、breakpoint または frame が変化したときにアプリケーションをアクティブ化する箇所を追跡します。完了条件は、設定可能なオプションによってデフォルトでは現在のフォアグラウンド動作を維持しつつ、リモートファイルを開く際には lldb にフォーカスを残せることです。これを external-editor ワークフローで検証します。
