rule-engine | library implements JSON Rule evaluation

rule-engine is a Java library. rule-engine has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub, Maven.

This library implements JSON Rule evaluation used internally by the Dassana engine. The grammar of a JSON rule can be found at src/main/antlr4/RuleSet.g4. The original code can be found here. The grammar has been significantly changed allowing for easier addition of rule operators. A JSON rule is simply a JSON path followed by operator and value: . The value can be optional in the case of generic operators. We use the jayway library for JSON path implementation. For testing purpose, we highly recommend using (make sure Jayway is selected in the right-side panel). Following operators are available-. A lot many other operators will be made available in future releases. You can read the ANTLR grammar located at src/main/antlr4/RuleSet.g4 but if you are not familiar with ANTLR, the following examples will help. Also, refer to unit test src/test/java/app/dassana/ruleengine/GrammarTest.java.
