#Dependencies:

	#This bash script requires Node.js to be installed: https://nodejs.org/en/
	#Once Node.js is successfully installed, clone the Pyret Git repo: https://github.com/brownplt/pyret-lang
	#Follow the instructions in the README under "Installing" to install a local copy of Pyret

#Usage: ./run-pyret.sh relative/path/to/pyret/file/from/Pyret/repo/file.arr

#This bash script expects the input relative path to be from the Pyret repo to the Pyret files, NOT from the location
        #of this script to the Pyret files

#NOTE: Due to an open issue in Pyret, only relative paths can be used for compilation

#Description:
	#This program compiles a specified Pyret .arr file to <file>.jarr in the same directory, then runs the output file
	#The output of the compilation and running can be redirected to a file using &>

PYRETDIR="../pyret-lang/" #PATH TO PYRET REPO, MUST BE CHANGED FROM DEFAULT
