Happy new year, you all! I'm pleased to announce three new packages on Hackage: * salvia-0.0.4: A lightweight modular web server framework. * orchid-0.0.6: A(nother) Wiki written in Haskell, currently using Darcs as a versioning back-end and Salvia as the application server. Orchid ships as a library that can be installed as a server module for the Salvia framework. * orchid-demo-0.0.4: A simple demo application using Salvia and Orchid to serve an example darcs repository. An online demo of the wiki can be found at [1]. The front-end is a typical Ajax application and heavily relies on the availability of JavaScript. A more plain (REST like) web interface to system can be found at [2]. You can signup, login and edit/create some pages. Feel free to play around, it's just a demo. Orchid has an abstract notion of a versioning back-end, theoretically allowing for multiple versioning systems. Currently only a Darcs back- end is available, but it shouldn't be too much work to implement a liaison for Git, Subversion, Mercurial etc. The Wiki uses its own experimental document system with printers to HTML, LaTeX, PDF via LaTeX and some others in the making. The system makes us of the UUAGC [3] attribute grammar system, but is not required in order to build the package. The document system is plug-in based allowing easy addition of new structures. There are currently plug-ins for inline LaTeX formulae, HSColour'ed Haskell code snippets and a table of contents. Some others in the making. Be aware, this is an early release to allow people the play around with the packages and enable me to see how this all behaves in the wild. The tools are not yet finished and I cannot guarantee any form of stability. But, in my experience, they seem to `just work'. Most of the time. I had some trouble getting all dependencies right on systems other than my own. Using `cabal install' seems to behave differently from `./ Setup install' in the package directory, but this may vary from system to system. It is known to work at least on Macosx and Linux with GHC 6.8, 6.10 or even 6.11. Pdflatex is needed for PDF generation, dvipng for inline formulas. Have fun and best wishes for this new year! -- Sebastiaan [1] http://funct.org/wiki/ [2] http://funct.org/wiki/data/Index.html [3] http://www.cs.uu.nl/wiki/HUT/AttributeGrammarSystem
