HBooru.Network

Module providing functions to interface with some booru sites. Amongst other things, it should (semi-transparently) handle post count limits. The user should simply be able to ask for all images with certain rather than worrying about hard limits per page set by the sites &c.

fetchTaggedPosts :: (Postable s d, CoerceResponse d r) => s -> d -> [Tag] -> ExcIO [ImageTy s d]

Given a Site, DataFormat and a list of Tags, naively fetch the first page or so and parse it to the appropriate image type. Both the site and the format need to together form an instance of Postable and the data format has to exist in an instance of CoerceResponse. Uses fetchPostPage to fetch the data.

fetchTaggedPostsIndexed :: (CoerceResponse r a, PostablePaged s r) => s -> r -> [Tag] -> Integer -> ExcIO [ImageTy s r]

As fetchTaggedPosts but works with sites which allow indexing by page.

fetchPostPage :: (Postable s d, CoerceResponse d r) => s -> d -> [Tag] -> ExcIO r

Given an instance of Postable, CoerceResponse, and a list of Tags, fetch the post page.

fetchPostPageIndexed :: (PostablePaged s d, CoerceResponse d r) => s -> d -> [Tag] -> Integer -> ExcIO r

Given an instance of Postable, CoerceResponse, and a list of Tags, fetch the post page.

fetchResponse :: CoerceResponse r r' => String -> r -> ExcIO r'

Given a URL and protocol, tries to fetch a response.

fetchPostCount :: (Postable s r, Counted s r, CoerceResponse r a) => s -> r -> [Tag] -> ExcIO Integer

Uses fetchPostPage to parse the number of posts available based on provided Tags.

fetchAllTaggedPosts :: (CoerceResponse r a, PostablePaged s r) => s -> r -> [Tag] -> IO [ImageTy s r]

Attemps to fetch all posts from a site, from all its pages. The upper limit of images per page is used.
