Eclipse

Extend Eclipse's Resource perspective with facilities for working with the Nix software deployment system. In particular, the Navigator view should provide a list of available *.nix files, and the Outline view should provide a summary of the structure of the selected *.nix file. There should be actions added to add a component selected in the Outline view to the current user environment, to upgrade a component when a new release is available, and to roll back to a previous version of the user environment. Optionally, you might like to add a specialized editor for *.nix files, and/or promote your work to a perspective or a feature.

Proxima Based Form Editor

Use the AG/Proxima system to produce an editor for a language like that was designed by Maarten de Heus to describe structures like the Dutch tax forms. Such forms have:

• fields that may be named, like spreadsheet cells
• conditional questions, that may depend on computed values or answers given already
• a nested layout
• an editor for specifying questions
• optional: SQL queries that fill out specific values to be displayed

Plug-in mechanism for AG

The AG system is a very simple system, and we do not want to extend it with all kind of bells and whistles. On the other hand, in order to be able to edit syntax trees with Proxima we have to add quite some rather straightforward code. These include special attributes to keep track of the identity of nodes, and unparsing rules. We propose to attack this problem by using hs-Plugins, and by extending AG with a general mechanism for adding properties to all kind of AG objects. If someone then wants to transform the AG data before it is emitted as Haskell code, he can do so by providing his own plug-ins for AG. The primary goal of this project is design and build the plug-in system, and to demonstrate its use for generating Proxima based AG's.
