Environment variables can override config values.
By default the core will listen to conf values in this order:
1. Environment variables
2. .conf file
3. Base values defined in the core
Environment variables keys are autogenerated based on the keys defined in .conf file.
// Example of conversions:
// SomeConfig => SOME_CONFIG
// myNestedConfig.opt1 => MY_NESTED_CONFIG_OPT_1
// LogDB.Opt.ClearTime => LOG_DB_OPT_CLEAR_TIME
// GM.InGMList.Level => AC_GM_IN_GMLIST_LEVEL
Unix:
$ export AC_DATA_DIR=/usr
$ AC_WORLD_SERVER_PORT=8080 ./worldserver
Windows:
> $env:AC_REALM_ID = '2'; .\worldserver
