#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))

(lambda (k v)

(lambda (x) (inspector x)) v)
