Fellow Haskellers, I am pleased to simultaneously announce the immediate release of the following related packages: Shellac, 0.6 Shellac-readline, 0.3 Shellac-vty, 0.1 Shellac is a framework for building read-eval-print style shells which uses configurable backend plugins. The major new feature of this release is the new Shellac-vty backend package, which uses the new Vty library (http://members.cox.net/stefanor/vty/) to do terminal I/O directly. It currently has basic line editing keybindings, paging, and a command history. The main package and Shellac-readline updates consist of minor API updates. The project page for these packages may be found at: http://www.eecs.tufts.edu/~rdocki01/shellac.html Additionally, the Lambda Shell 0.5 release is now available. The Lambda Shell is a shell environment for defining, evaluating and manipulating expressions of the pure, untyped lambda calculus. It is also a showcase for Shellac and a model for its use. This update contains little new functionality, but is mostly a maintaince update. The Lambda Shell project page may be found at: http://www.eecs.tufts.edu/~rdocki01/lambda.html If you wish to play with the new Vty Shellac backend, you may 'darcs apply' the following patch to the lambda shell darcs sources before building. It will cause the lambda shell to use the Vty backend rather than the readline backend. http://www.eecs.tufts.edu/~rdocki01/lambda-shell-vty.patch Thanks all and happy hacking, Rob Dockins
