Automatically look for a free port in case of collisions

[TechnicJelle]

When running multiple projects, port collisions can happen.

BlueMap itself already warns about double port usage.

But maybe I want to automatically look for a free port?

• Fully automatically?

  • No port configuration in the Simplified Config View. Every time the server starts, it will port sniff (from 8100 up) to find the next free port, writes that to the config, and only then starts up the BlueMap-CLI process.
  • When Core config has been switched to Avanced View, this whole step is skipped. So you might see the BlueMap warning about port conflicts.

• Or you get a confirmation popup:

  "Port already in use by another (BlueMap?) process. Do you want to automatically find a free port? This will modify your Core config."

  And then it will do some port sniffing (from 8100) to find the next free port.

  Moment:

  • When clicking start, Dart first checks if there is already something running on 8100.
  • Or only when BlueMap's own error pops up?
