geojson Hackage

A thin GeoJSON Layer above the aeson library

Building the project

Install the dependencies with:

cabal install --only-dependencies

Optionally add --enable-tests if you intend to run the unit tests

The project must be "configured" at least once everytime geojson.cabal changes, this can be done with:

cabal configure

If you wish to run the unit tests you will have to run:

cabal configure --enable-tests

Then finally build it with:

cabal build

See cabal build --help for more build options.

Running Unit Tests

After running cabal build, you can run the unit tests with the command:

cabal test

Adding Unit tests

Currently only files in the src/ directory are searched for tests, it is assumed that the code in main/ is a thin layer of code that uses modules from src/.

Development: Cabal Dependency Hell?

Cabal's great, but when you are developing a few different projects with their own dependency chains, sometimes installing all your libraries to the same place causes problems,

Consider trying [cabal-dev] cabal-dev. In terms of using it, all thats required is replacing cabal with cabal-dev in all the above command lines.

It will download and install all the dependencies for your project and install them in a cabal-dev/ directory in your project directory, and they will only be used for this project.

Those with newer versions of cabal (>= 1.18 I think) can skip cabal-dev and instead run cabal sandbox init, and just start runnign the above instructions as is from cabal install --only-dependencies
