Nim Google Photos parser

Fetches info and photos from public Google Photos album share urls

Usage

See tests/test_http.nim for an example fetching from an online url.

# create state object (ref object)
let gphoto: GooglePhotos = newGooglePhotos()

# following callbacks are available
# if undefined, it will skip the parsing of photos/album info (in case you need to save memory)
gphoto.photoCb = proc (photo: PhotoInfo) = ...
gphoto.infoCb = proc (info: AlbumInfo) = ...

# feed html into the parser, can be called multiple times
# returns true while parsing is in progress, returns false when complete or error occured while parsing
# takes string or Stream. Stream variant takes optional chunkSize (default = 1024)
gphoto.parseHtml(input: string): bool
gphoto.parseHtml(s: Stream; chunkSize: int): bool

# call to clean the state/photos stored inside state object
# does not reset callbacks
# newGooglePhotos() calls this internally
gphoto.init()

# pass a photo url to this to request a different resolution.
# keeps aspect ratio (contain size), image may be smaller than requested size
googlePhotoUrlSize(url: string; width: int; height: int): string

# following types are for photos and album info:

type
  PhotoInfo* = object
    url*: string
    id*: string
    width*: int
    height*: int
    imageUpdateDate*: BiggestInt
