Re: [ANN] silc - a tiny entity database for clojure (games)
Is it possible to retrieve all entities with a set of attributes, regardless of the attribute values? Not yet, I haven't indexed for it. You could approximate it using the ave index if you just concat any set of entities under any value. However it would require the attributes you are interested in participating in the ave index. It would be a worthy edition though so I'll look at it unless somebody wants to submit a pull request. Cool project! Did you try using the pldb built into core.logic? I have a similar system built atop pldb backing one of my side projects and I'm very happy with it. I do like pldb and core.logic and have used them in the past - I would very much like to introduce an optional core.logic front-end to this, however it was important to me that the primary interface was perhaps less declarative but with stronger performance guarantees as my use case for this is for game development. -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: [ANN] silc - a tiny entity database for clojure (games)
Coincidentally, I put together a similar library a few months ago ( https://github.com/weavejester/ittyon), but I didn't think anyone else would find it useful. It looks like there are more people experimenting with games in Clojure than I thought. - James On 3 December 2014 at 21:30, dan.stone16...@gmail.com wrote: I have released an update to the lib with a new index the `attribute-entity` index, and improved the readme (I hope).

A pure entity database would have been useful for a game I was working on last month. I'll try it out for the next one. Thanks for publishing it!

This is a very nice example of abstraction. Using a hash-map is just an implementation detail. However I'd be very interested to hear if there are any other compelling use cases for this.
