Readme for factual-api-0.6.0


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




This driver targets ghc 7.4.1 and The Haskell Platform 2012.2.0.0. Please follow the installation instructions for your specific platform to install ghc and The Haskell Platform.

You'll need a Factual account to use this driver. If you don't have one yet, it's free and easy to get one.

Installation from cabal

$ cabal install factual-api

Installation from git

$ git clone
$ cabal install hoauth
$ cabal install aeson
$ cabal install MissingH


To run the integration tests you'll need an to create a yaml file at ~/.factual/factual-auth.yaml to store your Factual credentials:

key: MYKEY
secret: MYSECRET

Load the tests file into ghci to run the tests:

$ ghci test/Tests.hs

Next you use the following functions to run the unit and integration tests respectively:

*Main> runUnitTests
Cases: 53  Tried: 53  Errors: 0  Failures: 0
Counts {cases = 53, tried = 53, errors = 0, failures = 0}
*Main> runIntegrationTests
Cases: 14  Tried: 14  Errors: 0  Failures: 0
Counts {cases = 14, tried = 14, errors = 0, failures = 0}


You can read library documentation by visiting the Hackage page.

The github wiki also provides thorough documentation and examples for each feature.


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.
