Readme for factual-api-0.1.0


This is a Haskell driver for Factual's public API.



This driver was developed on ghc 7.0.4 and The Haskell Platform 2011.4.0.0. Please follow the installation instructions for your specific platform to install ghc and The Haskell Platform.

Installation from git

$ git clone
$ cabal install hoauth
$ cabal install aeson

Note you may require libcurl to install hoauth. On lucid you can run:

$ sudo apt-get install libcurl4-openssl-dev

Installation from cabal

$ cabal install factual-api


Load the tests file into ghci to run the tests:

$ ghci test/Tests.hs

To run the response tests you'll need an API key and secret, but you can always run the query tests:

*Main> runQueryTests
Cases: 33  Tried: 33  Errors: 0  Failures: 0
Counts {cases = 33, tried = 33, errors = 0, failures = 0}
*Main> runResponseTests "mykey" "mysecret"
Cases: 4  Tried: 4  Errors: 0  Failures: 0
Counts {cases = 4, tried = 4, errors = 0, failures = 0}


You can read library documentation by opening docs/index.html in your browser.


See the examples directory for examples of each query type. To run an example go to the project root and execute these commands:

$ ghc -o example examples/ReadExample.hs --make
$ ./example mykey mysecret

In this example replace mykey with your key and mysecret with your secret. Note that compiling the source code generates .o and .hi files in the source directories.
