Bidirectional Utils.cycle() for Framer

Framer's Utils.cycle() extension that allows you to browse arrays in both directions (instead of returning only next item).

How To Use (Try the live demo)

or

• Copy the Utilscycle.coffee file to your prototype's modules folder.
• Call Utilscycle = require "Utilscycle" in your Framer prototype.
• Now your Utils.cycle() can iterate in both directions.
• To return next item, call your cycler() with no or true as an argument
• To return previous item, call your cycler() with false as an argument

Utilscycle = require "Utilscycle"

alphabet = ["a", "b", "c", "d", "e", "f", "g", "h"]

cycler = Utils.cycle(alphabet)

# cycler(none or true) => next
# cycler(false)        => previous

print cycler()      # Outputs "a" (next)
print cycler()      # Outputs "b" (next)
print cycler(true)  # Outputs "c" (next)

print cycler(false) # Outputs "b" (previous)
print cycler(false) # Outputs "a" (previous)

If you don't want to load this silly thing from another file, you can copy its code from Utilscycle.coffee
