reddit for haskell
A Haskell library for interacting with the Reddit API. Requires api-builder, but you will probably have to install it from the repository, because it needs a newer version than the one that's on Hackage.
### Basic usage
Almost everything is inside the Reddit monad, which handles errors and rate limiting (if you use runRedditWithRateLimiting) for you seamlessly – you can run the Reddit monad with runReddit user pass, which logs you in, grabs a token and starts running your actions.
Most of the time you can get away with importing Reddit.API and Reddit.API.Types and most of the stuff is available from there.
Here are some examples of functions that are useful:
getPostInfo :: PostID -> Reddit Post
getPosts :: SubredditName -> Reddit PostListing
savePost :: PostID -> Reddit ()
deletePost :: PostID -> Reddit ()
Most of the functions available have prime (') versions which accept extra options (before, after and limit api params).
For example, getPosts :: SubredditName -> Reddit PostListing corresponds to getPosts' :: Options PostID -> ListingType -> SubredditName -> Reddit PostListing, and most other functions follow this pattern.
Testing
The test test suite will run the tests that don't rely on doing any IO, but the test-io should be used too to ensure that IO functions do what they're supposed to do. If you want to run the IO suite, add a file test.cfg to the reddit/ directory, containing (one field per line):
- a reddit username
- a reddit password
- a subreddit name (the user should be a moderator for the subredit)
Run cabal test test-io and the tests should pass.
