Keep fsc (Fast Scala Compiler) alive so intellij doesn't lock up when fsc shuts down when idle.

fsc-idea.sh

#!/bin/bash
JAVA_OPTS="$JAVA_OPTS -Xmx512M -Xms64M" fsc -shutdown

DUMMY=$(mktemp -t fsc-dummy.$USER.XXXXX)
echo "object Dummy { val answer = 42 }" > $DUMMY
trap "rm -f $DUMMY" EXIT

while true; do
  echo Compiling dummy...
  scala $DUMMY
  sleep 1500
done
