Is there any Rules Engine/Inference Engine for Go

Question

We want to implement our business logic using Go, but we cannot find any good implementation of rules engine/inference engine for Go. Does anyone have any experience or suggestions?

Answer 1

There is a project that aims to implement an ISO Prolog compiler in Go:

• GoLog.

I haven't tested it, but given that it implements some basic Prolog, that should be quite a capable rule-based reasoning engine, AFAIS.

Otherwise, a search for "rule" over at godoc.org also yields a bunch of packages:

• godoc.org/?q=rule

Answer 2

The best example of something like this to my knowledge is the 'table-driven' approach to unit tests taken in much of the standard library. For example, the fmttests.

Beyond that, Go is a powerful, expressive language. What do you actually need? There are a number of examples of state machine implementations in Go, and a number of web frameworks with declarative JSON configuration.

If you mean proper logic programming, there's no popular Go library for it yet.
