This project provides a library for creating general purpose "Rule" objects from a logical expression which can then be applied to arbitrary objects to evaluate whether or not they match.
Project description
This project provides a library for creating general purpose “Rule” objects from a logical expression which can then be applied to arbitrary objects to evaluate whether or not they match.
Documentation is available at https://zeroSteiner.github.io/rule-engine/.
Example
import rule_engine
# match a literal first name and applying a regex to the email
rule = rule_engine.Rule(
'first_name == "Luke" and email =~ ".*@rebels.org$"'
) # => <Rule text='first_name == "Luke" and email =~ ".*@rebels.org$"' >
rule.matches({
'first_name': 'Luke', 'last_name': 'Skywalker', 'email': 'luke@rebels.org'
}) # => True
rule.matches({
'first_name': 'Darth', 'last_name': 'Vader', 'email': 'dvader@empire.net'
}) # => FalseCredits
