Feature Request: detect and reuse MacVim instance to open file by mvim:// url

Greeting!

I configure mvim:// in React Developer Tools to open file in MacVim from the browser extension.

mvim://open?url=file://{path}&line={line}

It works good, but there's a small issue. The issue is that MacVim doesn't reuse the instance that I opened if the target file hasn't been opened. For example, I launch MacVim from /path/to/my-project, and I open files /path/to/my-project/{a,b,c}.js from React Developer Tools. They have different results:

I hope the c.js can be opened like a.js and b.js.

I have a workaround in favor of Raycast Script Command deeplinks. My script launch MacVim with specified servername, the launched instance will be reuse if I execute the script again. Here it is (I have multiple ones generated by another script):

#!/bin/bash

# Required parameters:
# @raycast.schemaVersion 1
# @raycast.title Vim Launch
# @raycast.mode silent
# Optional parameters:
# @raycast.icon ✅
# @raycast.packageName vim-launch
# @raycast.argument1 { "type": "text", "placeholder": "file path", "optional": true }
# @raycast.argument2 { "type": "text", "placeholder": "line number", "optional": true }

# Documentation:
# @raycast.description Open vim startify session

export PATH=/Applications/MacVim.app/Contents/bin:$PATH

open_file()
{
    if [[ -n $1 ]]; then
      mvim --servername THE_SERVER_NAME --remote-send "<c-w>:tabedit $1<CR>"
    fi
    if [[ -n $2 ]]; then
      mvim --servername THE_SERVER_NAME --remote-send "$2G"
    fi
}

SERVERS=`mvim --serverlist | grep -i THE_SERVER_NAME | awk '{print tolower($0)}'`
for server in $SERVERS; do
  if [[ $server == "THE_SERVER_NAME" ]];
  then
    osascript >/dev/null <<END
      tell application "System Events" to tell process "MacVim"
        set frontmost to true
        windows where title ends with "THE_SERVER_NAME"
        if result is not {} then perform action "AXRaise" of item 1 of result
      end tell
END
    open_file $1 $2
    exit 0
  fi
done

LANG=en_US.UTF-8 mvim --servername THE_SERVER_NAME +SLoad\ THE_SERVER_NAME >/dev/null 2>&1
# wait for server registration
sleep 1
open_file $1 $2

With this script, I replace mvim:// url with Raycast's deeplink:

raycast://script-commands/vim-launch?arguments={path}&arguments={line}

It's fixed! However it would be better to have native support in MacVim.

I would suggestion to add feature to detect the instance I want to open file with (like if the opening file path is in the working directory of an instance, the closest one), or add another parameter to specified the instance.

Thanks!

この issue では MacVim の mvim:// URL 処理とインスタンス/サーバーの選択について述べられていますが、ソースファイルやテストは示されていません。まず、URL のエントリポイントと、既存の MacVim インスタンスを選択するロジックを探します。未オープンのファイルが適切な既存インスタンスを再利用でき、報告された a.js、b.js、c.js のケースをカバーできれば完了です。
