# Haskell Urbit API

This library helps you talk to your Urbit from Haskell, via HTTP.

The "Urbit Airlock" API is a command-query API that lets you hook into apps
running on your Urbit. You can submit commands (called "pokes") and subscribe to
responses.

See the `test.hs` file for some example usages.

## Design

The Urbit vane `eyre` is responsible for defining the API interface. The path to
the API is `/~/channel/...`, where we send messages to the global log (called
`poke`s) which are then dispatched to the appropriate apps. To receive
responses, we stream messages from a path associated with the app, such as
`/mailbox/~/~zod/mc`. Internally, I believe Urbit calls these `wire`s.

`urbit-airlock` handles most of the path, session, and HTTP request stuff
automatically. See the haddocks for more details.

This library is built on req, conduit, and aeson, all of which are very stable
and usable libraries for working with HTTP requests and web data.

## TODO

- fix test suite on travis (OOM when trying to compile urbit)
- more sophisticated test cases, also use cabal test instead of homegrown thing
- add an exe that wraps the library with a cli
- port to ghcjs
- put some examples in the docs
