Expr download | SourceForge.net

Expr package provides an engine that can compile and evaluate expressions. An expression is a one-liner that returns a value (mostly, but not limited to, booleans). It is designed for simplicity, speed and safety. The purpose of the package is to allow users to use expressions inside configuration for more complex logic. It is a perfect candidate for the foundation of a business rule engine. The idea is to let configure things in a dynamic way without recompile of a program.

Features

Seamless integration with Go (no need to redefine types)
User-friendly error messages
Reasonable set of basic operators
Builtins all, none, any, one, filter, map
Static typing
Fast (benchmarks): uses bytecode virtual machine and optimizing compiler
