Rules language

[milosdakic]

Would be awesome if Ruler could do something similar to https://github.com/hoaproject/Ruler, where rules can be defined like so:

'group in ["customer", "guest"] and points > 30'

This would allow storage of rules within databases or other formats.

You can serialize the parsed rule then store it, at least that's what we are doing with this ruler

@yellow1912 - How do you handle the error generated with trying to serialize the closure object? What function are you calling to get just the parsed rule?

For what I have read in the Documentation, this idea would be a perfect match for another Project, using Ruler as dependency and building some kind of external Domain Specific Language (DSL) which leverage the usage of Ruler itself.

I did something similar for an old Project of mine by using a DSL modelling framework which was Eclipse Based. At the time was a huge help when generating the Ruler code to use later on for validation.

Perhaps it could be integrated with this UI rule maker that has a defined JSON format. Yeah I know, it’s just jQuery and not NewestXYZ-JS framework. But still.

It is a good idea. Though IMHO, aspects like this should be done in a separate package. Not in this library.
