• 2. Usage
• 3. JSON configuration
• 4. SystemTray icon

1. Building

go build -o="runsyncapps.exe" ./cmd/

On Windows, You can add the build flag -ldflags="-H windowsgui" to avoid the console to open when starting the app.

2. Usage

runsyncapps.exe --config=myconfig.json --log

• config : path of the config file (config.json by default)
• log : log events in a trace_<timestamp>.log file (disabled by default)

3. JSON configuration

The configuration file looks like this:

{
    "waitCheck": 10,
    "waitExit": 10,
    "applications": [
        {
            "path": "C:\\Windows\\System32\\dxdiag.exe",
            "useExistingInstance": false,
            "killOnExit": true
        },
        {
            "path": "C:\\Windows\\System32\\charmap.exe",
            "useExistingInstance": false,
            "killOnExit": true
        },
        {
            "path": "C:\\Windows\\System32\\msinfo32.exe",
            "useExistingInstance": false,
            "killOnExit": false
        }
    ]
}

The parameters are the following:

• waitCheck: timer (in seconds) after the processes are being monitored
• waitExit: timer (in seconds) before the processes are being killed
• applications: array of application to start:
  • path: full path of the application
  • useExistingInstance: don't start a new instance if there is one already running
  • killOnExit: kill the application if it's running after another app has been killed

4. SystemTray icon

A system tray icon allows the using to exit the application without killing the child processes.

This works by default on Windows.

On MacOS you will need to bundle the application (see getlantern/systray lib info and official Apple documentation).
