VSHaskell - Visual Studio 2010 Haskell addin

This project provides a Visual Studio 2010 Haskell addin. The project was started by Well Typed with funding from Alexis Suzat. The code is all open-source under the BSD license.

Installation

To install VSHaskell follow these steps:

1. Install Visual Studio 2010, any edition except Express. There are free trails available from the Visual Studio website.

2. Install GHC 7.4.1. Later or earlier versions will not work. Make sure you leave "Add bin directories to PATH" checked.

3. Install the VSHaskell addin.

To test the addin, open a Haskell file (.hs extension) in Visual Studio 2010. There are two main features:

1. The Haskell will have syntax coloring. Keywords such as module should appear in blue.

2. The module will be type-checked as you type, and any errors will appear both in the Error List (display it from under the View menu) and with red wiggly lines in the editor.
