B-Con / Credit Card Generator
Last active January 2, 2025 05:06
This JavaScript function generates random number strings that pass the Luhn checksum, the test that credit card numbers must conform to. It assumes there is an HTML radio input to indicate which company issued the card. This code is from my webpage here: http://bradconte.com/cc_generator.html.

A Rubocop wrapper that checks only added/modified code
#!/usr/bin/env ruby
# A sneaky wrapper around Rubocop that allows you to run it only against
# the recent changes, as opposed to the whole project. It lets you
# enforce the style guide for new/modified code only, as opposed to
# having to restyle everything or adding cops incrementally. It relies
# on git to figure out which files to check.
#
# Here are some options you can pass in addition to the ones in rubocop:
