After adding 16 new card brands, I’m finding the single file is getting slightly more complex than I’d like.
There’s only about 270 lines of code, but it’s difficult to come up with logical arrangement as many brands have multiple ranges in entirely different areas.
An approach I’m considering creating a set of cb_1 thru cb_9 submodules
and move the logic for each leading digit into the submodule.
Of course, this is not practicable without a proper Mix project, so that’s the next major step.
I’ll also be introducing tests at that point as I’m not comfortable I’ve not broken some earlier brands.
