NovicapChallenge Store

Install

Assuming you have Elixir already installed, run mix deps.get && mix compile in the project folder.

Usage

0. Run iex -S mix and alias the store module so it's easier to use the functions:

alias NovicapChallenge.Store

1. Load products with json file. They should be stored in ./products. Calling without arguments loads the default products.json file.

Store.load_products()

2. Scan products.

Store.scan("VOUCHER")

3. Add rules. Current rules are: NovicapChallenge.Rules.DoubleVoucherRule and NovicapChallenge.Rules.ShirtRule.

Store.add_rule(NovicapChallenge.Rules.DoubleVoucherRule)
Store.add_rule(NovicapChallenge.Rules.ShirtRule)

3. Check the total.

Store.total
