Minimallist

A minimalist data driven data model library, inspired by Clojure Spec and Malli.

Usage

(ns your-namespace
  (:require [minimallist.core :refer [valid? describe]]
            [minimallist.helper :as h]))

(def hiccup-model
  (h/let ['hiccup (h/alt [:node (h/in-vector (h/cat [:name (h/fn keyword?)]
                                                    [:props (h/? (h/map-of (h/vector (h/fn keyword?) (h/fn any?))))]
                                                    [:children (h/* (h/not-inlined (h/ref 'hiccup)))]))]
                         [:primitive (h/alt [:nil (h/fn nil?)]
                                            [:boolean (h/fn boolean?)]
                                            [:number (h/fn number?)]
                                            [:text (h/fn string?)])])]
    (h/ref 'hiccup)))

(valid? hiccup-model [:div {:class [:foo :bar]}
                      [:p "Hello, world of data"]])
;=> true

(describe hiccup-model [:div {:class [:foo :bar]}
                        [:p "Hello, world of data"]])
;=> [:node {:name :div
;           :props [[[:class [:foo :bar]]]]
;           :children [[:node {:name :p
;                              :props []
;                              :children [[:primitive [:text "Hello, world of data"]]]}]]}]

Features

• validates, parses and generates data,
• fully data driven, models are hash-map based created via helpers,
• support recursive definitions and sequence regex,
• no macro, no static registry, pure functions,
• relatively simple implementation, easy to read and modify,
• cross platform (.cljc),
• valid? and describe run in Babashka

Non-goals (for now)

• does not integrate with anything else,
• does not try hard to be performant

Documentation

See the latest documentation on cljdoc for:

• A general description of the Minimallist project.
• How to use the helpers to build your models.
• How to validate, parse and generate your data.

Status

This is a work in progress, the API may change in the future.

More functionalities will be added later, once the API design is more stable.
