PXSL ("pixel") is a convenient shorthand for writing markup-heavy XML documents. It provides XML authors and programmers with a simple, concise syntax that they can use to create XML documents. For more advanced users, it offers customizable shortcuts and sophisticated refactoring tools like functional macros that can markedly reduce the size and complexity of markup-dense XML documents.
In Haskell, data type declarations, Parsec parsers, and HughesPJ pretty-printers very much resemble each other; supplying all three is virtuous, but involves a large amount of code duplication. syntran is a code generator designed to reduce the amount of duplication. Its source is similar to a Parsec LanguageDef-using parser, annotated with the unique information from the data type declaration and the pretty-printer which would normally not be found in a parser. It separates this information out to generate pure Haskell.
Riot is a tool for keeping (textual) information organised. It is a todo list and note manager, and a manager for whatever information one might collect. It has an interface resembling those of slrn and mutt and all text editing is done with an external editor, making it a nice browser for collections of text.
Asynchronous DNS Resolver for Haskell is a library that provides an asynchronous DNS resolver on top of GNU ADNS. Not all options are supported, but A, MX, and PTR lookups work nicely. There is also support for retrieving generic RR types, CNAMEs, and for NSEC zone walking. The library can be expected to work with fine ADNS 1.4 or later. It might also work with version ADNS 1.3, but that hasn’t been tested.
lhs2TeX is a literate programming tool. It is implemented as a preprocessor that generates LaTeX code from literate Haskell sources. It allows for and provides different styles for the formatting of code. You can easily select between representing operators with mathematical symbols or with ASCII approximations, as well as deciding whether or not to highlight keywords. The formatting of your own defined tokens may be adjusted. Preprocessor-style conditionals are supported, and Haskell can be used to generate parts of the document.
