Re: [Haskell-cafe] Typesafe API calls

I have noticed a steady increase in the number of downloads of the apis-0.0.1 package (now 67). However the number of downloads on the dependencies are far less (around 50%). Does this imply that people are having problem compiling the package? As the build process is a bit complex reports about this would be appreciated! Also, none of my packages can be found on hayoo, why is this? 2014-12-23 1:01 GMT+01:00 Fabian Bergmark :

I have uploaded a new version of the library

https://hackage.haskell.org/package/apis-0.0.1

I'have included 15 more APIs from Facebook and Dropbox. I have also uploaded documentation to Hackage.

I have been working on creating an autotools installation script that builds a makepkg package with the FFI bindings for Python and Java. I have tried it on Arch and it seems to work. If you want to try it out, check out the github repository.

Building on top of this, Im working on a library that uses Pipes to create producers (triggers) and consumers (actions), allowing one to create effects (recipes) of the kind, when I am tagged in a photo on Facebook, notify me via email. This very much resembles IFTTT but with static and typesafe compositions. Im experimenting with using my javascript interpreter to allow for more dynamic compositions.

Hello Fabian,

I have been dreaming of something like this for Haskell since I wrote a (non type-safe) python library to access any REST API generically[1]. This comes from a different (and more ambitious) angle than I had imagined.

I don't have time to test this just now, but I will keep it bookmarked. Thanks for sharing your hard work!

Regards, Jonathan

(https://hackage.haskell.org/package/apis-0.0.0). The goal of the library is to provide typesafe API calls to a large amount of existing APIs. By typesafe I mean that, for each API the library provides two types, Input and Output, and a function :: Input -> IO Output. Internally the library knows how to serialize Input to make an HTTP request and how to deserialize the response into Output.

Whats cool about this library is that it uses Template Haskell to generate the API interfaces. A combination of Open Data Tables, an internal YQL engine and JSON Schemas, all written in Haskell makes this possible.

Right now only two APIs are included (Swedish weather data and Swedish public announcement), but more APIs are soon to follow.

I have also implemented FFI exports of all types and functions so that, in combination with SWIG, this library can be used in almost any language. So far I have tried Java and Python with success.

If anyone would like to try it and respond with feedback it would be greatly appreciated! If you want any specific API supported, I can try to import that right away
