Any Golang libs for defining business logic in a serializable format?

Hi,

I want to transfer logic between systems via a restful API or RPC using something like jsonlogic.com. Has anyone seen a golang library that does something like this? even in XML (urgh!)?

I eventually found what I was after here: https://github.com/elgs/jsonql

I'm not familiar with jsonlogic, but have you checked out the encoding/gob package? Also, net/rpc?

Admiral_Aubergine:

What Im trying to do is find a format to define the logic, not send or receive it. Im already using net/rpc.

printf_hello_world:

Huh, interesting. I'm not aware of anything that does this in a way like jsonlogic (went and looked it up now), but maybe you could achieve the same sort of thing with reflect?

Toy example: https://play.golang.org/p/VJ9-F_x08K

Have you thought about go plugins? https://tip.golang.org/pkg/plugin/

PsyWolf:

You could definitely use this new language feature to generate go code from the JsonLogic format, write it to disk, and load/execute it on the fly.  Check out http://www.youtube.com/watch?v=tY4UKkgb5IY&t=19m53s for a great demo on go plugins. 

Edit: on second glance, since JsonLogic like don't use eval, you probably could implement a JsonLogic lib in go without plugins, but it'd be hard without duck typing.

"business logic" in serializable format ? 

Not exactly sure what you mean. If you want to transfer structured data via rpc/REST, you can use protobuf for that. I guess calling an rpc function can be termed as business logic. Does that answer your question ?

PsyWolf:

You could use something like https://github.com/robertkrimen/otto to call JsonLogic from your go code.

Want to achieve distributed map reduce like functionality? How about Lua/JS?
