checkout-system provides utilities to calculate a total checkout price from JSON data.
Documentation can be viewed at: godoc
The checkout package can be used in an external project by installing it by calling go get github.com/billiem/checkout-system/checkout,
and importing it with:
import (
"github.com/billiem/checkout-system/checkout"
)
The CLI functionality can also be used by cloning the github repository at github.com/billiem/checkout-system.
Once cloned, the program can be executed either via go run . followed by the checkout argument/ products flag, or by building the binary with go build ., and running it by calling ./checkout-system.
checkout-system accepts a positional command line argument for the checkout_data json location, and uses the -products flag to accept the product_data json location (used for pricing). If the argument/ flag is not given/ default relative locations will be checked as defined in the constants section of /checkout/cli.go
Filepaths accepted by these arguments can either be absolute or relative, if they are relative, they will be relative to the location of the binary. If the binary is installed via go install, this will be relative to $GOBIN
Example calls:
from the ./checkout-system directory using go run . with no argument/ flag
go run .
from the ./checkout-system directory after using go build . with a relative checkout_data argument
./checkout-system checkout_data.json
