Currently this project is only suitable when the host machine is a windows machine.

synergy-listener listens for changes in a synergy 3 host's log file, parses the tail-end, and writes what computer is currently being controlled to a .txt file. You can then hook into this .txt file via other applications/processes to react based on which computer is currently being controlled. For example, the advanced scene switcher plugin for obs can switch scenes based on the contents of a text file, the coordinates of your mouse, and more. I combine this with the obs ndi plugin to send a video feed from each PC in my setup to my capture pc. From there, I can automatically switch to whatever scene represents whichever display / section of a display on whichever computer I'm currently controlling with synergy. See the video below to witness this in action.

Run the following command in powershell.

winget install Microsoft.PowerShell Git.Git

Run the following command in PowerShell in the directory you desire (ie cd ~/Documents).

git clone https://github.com/ninbura/synergy-listener

• Create config.json in the root of the repository you just cloned.

  • New-Item -Type File -Name config.json

• Provide the SynergryLogPath, OutputFileDirectory, & RetryOnFailure within said configuraiton.

  • {
      "SynergyLogPath": "C:/ProgramData/Synergy/logs/synergy.log",
      "OutputFileDirectory": "//192.168.2.4/a-sexy-capturer/Users/gabri/Documents",
      "RetryOnFailure": true
    }

• The RetryOnFailure option will make synergy-listener attempt to relocate the relevant files/paths set in the configuration if it can't find them. Useful if you're using network locations.

Simply run ~install.bat at the root of the repository as administrator. After this, the proccess should automatically startup with your computer. From now on, when you switch computers with Synergy, the current-computer.txt file should contain the computer currently being controlled by Synergy. current-computer.txt should be located within your specified OutputFileDirectory.

If you're running into issues, or it seems like synergy-listener isn't running; check the synergry-listener.log file in root where you cloned the repo.

• Run ~stop.bat as administrator to stop the schedule task.
• Run ~restart.bat as administrator to restart the task if it's not working, or if you've updated the config.json file.
• Run ~uninstall.bat as administrator to uninstall and remove the task, feel free to delete the repository after this.
