We are pleased to announce an alpha/preview version of VHS (Visual Haskell), which integrates the Haskell functional language with the Microsoft Visual Studio .NET 2003 IDE, and VHS-AM, which allows the use of VHS with the Microsoft Assignment Manager tools. This preview version supports: - Syntax coloring - Brace matching through CTRL+] (including "module/where", "let/in", etc.)* - Brace highlighting (including "module/where", "let/in", etc.)* - Brace matching text indicated in the status bar - "TODO" comments in code are added to the task list and can be reached by double-clicking it - Quick-info* - Word-completion* - Method tip* - Member-list popup* - Haskell Console Application creation - Haskell Console Application compilation (integrated with GHC) - Haskell Console Application execution - The presence of parse errors is indicated on-the-fly in the task list (specific errors are still not specified) - Error source location can be reached by double-clicking the task list - Haskell Assignment Manager exercise creation and advertisement - Haskell Assignment Manager exercise answering and submission - Compilation checking (via GHC) and output checking of Haskell exercises by Assignment Manager server Please note that this first release of VHS has some known bugs: - A VS.NET session can become unstable if you open a .hs file or create a Haskell Console Application project. - After opening a .hs file, the devenv.exe process is not being killed when VS.NET exits. - The above features marked with * sometimes do not work 100% as expected, mainly if the haskell module under development has errors. - Some features do not work in a "inter-module fashion". - The Visual Haskell logo does not disappear from VS.NET splash screen after uninstall. Note: development of a Visual Studio plugin for Haskell has been proceeding on two fronts. Simon Marlow & Krasimir Angelov have been working on adding complete editor support and a project framework integrated with Cabal, whereas this release is based on a fork of the codebase several months ago, and has a different feature set. We hope to combine these versions and make further releases in the future.
