Programs with command-driven interfaces require a lot of boilerplate to handle input validation, error checking, and type casting. Malt abstracts this boilerplate into a small set of easy-to-use functions.
import malt
options = [
'spam',
'eggs i:count s:style=scrambled',
'sausages b:spicy=False',
]
while True:
response = malt.offer(options)
if response.head == 'spam':
print('spam, spam, spam, spam')
elif response.head == 'eggs':
print((response.style+' eggs ') * response.count)
elif response.head == 'sausages':
if response.spicy:
print("!!!SAUSAGE!!!")
else:
print('sausage')
else:
pass> spam
spam, spam, spam, spam
> eggs 2
scrambled eggs scrambled eggs
> eggs 2 style="over easy"
over easy eggs over easy eggs
> sausage
sausage
> sausage spicy=True
!!!SAUSAGE!!!
> potatoes
