#lang racket

;; let's try to make a pokedex in racket!

;; first step will be to write a function to query the pokeAPI
;; like so, https://pokeapi.co/api/v2/pokemon/ditto

;; once there is a function in place that returns data I will
;; have a choice to make -- do I want to always query the API,
;; do I want to cache results, or do I want to create an offline
;; repository of poke-data to search through and sometimes update?


;; basic GET request
(require net/url)
(require json)

; 🤔
(require slideshow/pict racket/draw)

;; API URL
(define *POKE-API* "https://pokeapi.co/api/v2/")


(define (get-pokemon id)
    "queries the api, returns a butt ton of info"
	(call/input-url (string->url (~a *POKE-API* "pokemon/" id)) ; ~a, like string-append but appends *either* strings or numbers to a string
                get-pure-port
                (compose string->jsexpr port->string))) ; QUESTION: could I use read-json here, instead?

(define (dex-entry id)
    "selects the info we need from the api, builds a hash table of the data that will build the entry"
    (let ([poke-data (get-pokemon id)])
        (define entry-data (make-hash))
        (hash-set! entry-data "name" (hash-ref poke-data 'name))
        (hash-set! entry-data "id" (hash-ref poke-data 'id))
        (hash-set! entry-data "sprite" (hash-ref (hash-ref poke-data 'sprites) 'front_default))
        (hash-set! entry-data "stats" (hash-ref poke-data 'stats))
        (hash-set! entry-data "types" (hash-ref poke-data 'types))
        entry-data))

(define (inspector h)
  "display the contents of a hash table for human eyeballs and let the hash table fall back out"
  (hash-map h
            (lambda (k v)
              (if (list? v) (map ; consider making this if a cond and testing for lists/hash tables to recursively dive into nested data
                             (lambda (x) (inspector x)) v)
                  (display (~a "  key: " k "\nvalue: " v "\n=====\n")))))
  h)

(inspector (dex-entry 11))
(inspector (dex-entry "bulbasaur"))

(define img (hash-ref (dex-entry 11) "sprite"))

(define display-image (bitmap (make-object bitmap% img)))

(frame (scale display-image 0.3)) ; this doesn't actually seem to work with URLs/PNGs
