# Forcibly disable Ruby GC:

export PROFILE_RUN= # ruby-prof|memory_profiler

# If using ruby-prof, what mode to run it in:
export RUBY_PROF_MODE=allocations  # ALLOCATIONS, CPU_TIME, GC_RUNS, GC_TIME, MEMORY, PROCESS_TIME, WALL_TIME

# Dump various PNGs showing the results of given nodes in the DAG over time.
# This is VERY VERY memory intensize!  Don't try to use it for a long run!
# Current nodes: perlin, stretched, shifted_0, shifted_1, shifted_2, shifted_3, spotlit, output
# ... however you probably don't care about shifted_0..shifted_2.
export DEBUG_NODES= #spotlit,output #perlin,stretched,shifted_3,spotlit,output
