Application for OS X Ruby

Question

It's easy to create a ruby ​​OS X app - create a structure like this:

xxx.app
└── Contents
    ├── Info.plist
    ├── MacOS
    │   └── xxx
    └── Resources
        └── xxx.icns

and enter the code to execute in xxx. But the launch time is noticeable, so I want this application to stay in the background and run some method when the application is open: therefore, when I launch this application for the first time, it executes the code that remains in the background when I I start another time, the application is already in the background, so it just starts the specified method.

Minimum Info.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>CFBundlePackageType</key>
  <string>APPL</string>
  <key>CFBundleExecutable</key>
  <string>newTabHere</string>
  <key>CFBundleIconFile</key>
  <string>newTabHere</string>
  <key>LSUIElement</key>
  <true/><!-- hides icon from Dock -->
</dict>
</plist>

Slowness occurs due to the launch time required for the ruby ​​interpreter. Therefore, it does not slow down for a bash script or objective-c.
