Command line options
Along with the command line options that the official launcher uses, there are some additional ones for this launcher.
List of options and there use on Wurmpedia
dumpsettings=<name>
Dumps all of the official server settings for the local server in the named database folder, along with any other options specified by mods, in a file called server_settings.properties which it puts in the database folder. The options are split into key=value pairs, with comments dividing the settings that apply to different mods.
e.g:
#Server settings file for Creative.
#Sun Nov 15 15:51:00 GMT 2015
#Official Gameplay Settings
#Sun Nov 15 15:51:00 GMT 2015
gameplay.SKMIND=25.0
gameplay.KINGSMONEY=100
gameplay.UPKEEP=false
gameplay.RANDOMSPAWNS=true
gameplay.TESTSERVER=false
...
After creating the file, the launcher exits.
loadsettings=<name>
Loads the settings from the server_settings.properties file created by dumpsettings for the local server in the named database folder.
After loading the settings, the launcher starts as normal. So if you specify loadsettings and start it will load the settings and start the server without launching the GUI.
