Sublime Text 2 Rspec Runner (Dir Traversal Version) with FIFO tools. `fifo_reader` and `fifo_writer` use namespaces to keep jobs seperate. The rspec plugin for Sumblime writes the the 'rspec' fifo and can be read using the `fifo_reader rspec` command. Killing this process clears the remaining items in the queue. `fifo_reader <space>` can also be…

fifo_reader

#!/usr/bin/env zsh
PIPE="/tmp/$1.fifo"

# Create the FIFO
if [ ! -p $PIPE ]; then mkfifo -m 0777 $PIPE; fi

# Trap kill traps
trap "rm -f $PIPE" SIGINT
trap "rm -f $PIPE" SIGTERM

# While the FIFO exists run the commands
while [ -p $PIPE ]; do
  if read COMMAND < $PIPE; then
    clear
    /usr/bin/env zsh -c "$COMMAND"
    wait
  fi
done

# Kill any writers writing to this fifo
ps aux | grep 'fifo_writer $1' | tail -n +2 | awk '{print $2}' | xargs kill

exit

fifo_writer

#!/usr/bin/env zsh
PIPE="/tmp/$1.fifo"

# Error if Pipe does not exit
if [ ! -p $PIPE ]
  then
  echo "Pipe: $PIPE is not available"
  exit 1
fi

# Append to Pipe
echo $2 >> $PIPE
wait
exit
