BF to C Converter (source at https://github.com/matslina/bfoptimization). Change line 74 to convert your own BF code: ir_to_c(bf_to_ir("+++.")). Example output from this program https://ideone.com/z16KPJ.

	from collections import namedtuple

	# These map directly to the 8 regular brainfuck instructions. The
	# exception is the offset parameter, which would be 0 in regular
	# brainfuck, but can here indicate an offset from the current cell at
	# which the operation should be applied.

Attempt at a basic STRIPS PDDL grammar parser for pegjs.org. To use, visit http://pegjs.org/online and paste the below grammar into the left-side window. In the right-side window, paste a PDDL domain file, such as https://spark-public.s3.amazonaws.com/aiplan/resources/random-domain.txt. The output will display in the Output panel.

	/*STRIPS PDDL parser for http://pegjs.org/online
	For example of parsing this grammar, see https://gist.github.com/primaryobjects/1d2f7ee668b62ca99095
	Example PDDL domain to parse:

	(define (domain random-domain)

DOS batch file to launch a NodeWebKit app. NodeWebKit has a habit of occasionally immediately quitting when trying to launch it. This script times the launch and quit times, so if the app exits in less than 5 seconds, we re-launch the app, until we finally get a proper launch.
