# NLDL

**N**atural **L**anguage for Clojure's **D**ata**l**og flavor

as present in Datomic, Datascript, Datahike etc.

Inspired by [nl-datalog](https://github.com/harc/nl-datalog) and its [demo](http://alexwarth.com/projects/nl-datalog/)

## Usage

```clojure

(ns examples.basic

  (:require [nldl.core :as nldl]

            [datascript.core :as d]))

(nldl/nl->dl

"find movie

 where movie title is avatar

 movie rating is 8")

;; => [:find ?movie :where [?movie :title "avatar"] [?movie :rating 8]]

(def db

  (-> (d/empty-db)

      (d/db-with

       [{:db/id 1 :title "titanic" :rating 3}

        {:db/id 2 :title "avatar" :rating 8}

        {:db/id 8 :title "avatar 2" :rating 5}

        {:db/id 3 :title "holy motors" :rating 8}

        {:db/id 4 :title "greener grass" :rating 9}])))

(d/q

 (nldl/nl->dl

  "find movie

  where movie title is avatar

  movie rating is 8")

 db)

;; => #{[2]}

(d/q

 (nldl/nl->dl

  "find movie

  where movie title is avatar

  movie rating is 8"

  {:find (fn [var] [:find (list 'pull var '[*])])})

 db)

;; =>  ([{:db/id 2, :rating 8, :title "avatar"}])

```

## Status: Alpha

Experimental! I'm toying with this for easier entry of datalog queries on mobile

(for my project [Zeal](https://github.com/den1k/zeal))

where Clojure Datalog's beloved parentheses, brackets, question marks and colons

are always at least two taps away.

Thanks to its simple text processing NLDL also allows for

accessibility enhancements through speech-to-text queries.
