Introducing the Headless Weather Wizard

Two things:
  • The Weather Wizard runs on a Raspberry PI
  • It can load (and save) a default composite, and reload it on a regular base
The idea is to run the Weather Wizard in some sort of batch mode, so it generates and stores composites on its file system, as long as you let it go.
You just need to run it this way:
On Windows:
set MEM_OPTIONS=-XX:NewSize=512m -XX:MaxNewSize=512m -Xmn768m -Xms1024m -Xmx1024m 
set MEM_OPTIONS=%MEM_OPTIONS% -XX:SurvivorRatio=1 -XX:PermSize=30m -XX:+UseParallelGC
set PRMS=-composite:./patterns/01.Favorites/01.3.00.Pacific.Sfc.500.Tropic.GRIB.ptrn
set PRMS=%PRMS% -interval:360 
set PRMS=%PRMS% "-pattern:/yyyy/MM-MMM | Auto_ | yyyy_MM_dd_HH_mm_ss_z | waz"
set command=java %JAVA_OPTIONS% -client -classpath "%CP%" -Dheadless=true main.splash.Splasher %PRMS%
start "Headless Weather Wizard" %command%
On Linux:
MEM_OPTIONS=-XX:NewSize=512m -XX:MaxNewSize=512m -Xmn768m -Xms1024m -Xmx1024m 
MEM_OPTIONS=$MEM_OPTIONS -XX:SurvivorRatio=1 -XX:PermSize=30m -XX:+UseParallelGC
PRM3="-pattern:/yyyy/MM-MMM | Auto_ | yyyy_MM_dd_HH_mm_ss_z | waz"
java $JAVA_OPTIONS -client -classpath "$CP" -Dheadless=true main.splash.Splasher $PRM1 $PRM2 "$PRM3" &
Notice the parameters -composite:, -interval:, and -pattern:. Same for the System variable -Dheadless=true.
This means that the pattern mentioned in -composite: will be reloaded every 360 minutes, and stored as stated in the -pattern: parameter.
