Yampa - HaskellWiki
Yampa is a domain-specific embedded language for the programming of hybrid (discrete and continuous time) systems using the concepts of Functional Reactive Programming (FRP). Yampa is structured using Arrows, which greatly reduce the chance of introducing space- and time-leaks into reactive, time-varying systems. Yampa was originally developed by the Yale Haskell Group based on the original idea o

Research papers - HaskellWiki
A lot of documentation exists about Haskell, and its foundations, in the form of research papers written by those investigating language design. An enormous research effort, by hundreds of researchers over the past 20 years, has gone into making Haskell such a great language. In general, if a feature is not well understood, it isn't going to become part of the language. Here is a selection of thos
Functional dependencies - HaskellWiki
Functional dependencies are used to constrain the parameters of type classes. They let you state that in a multi-parameter type class, one of the parameters can be determined from the others, so that the parameter determined by the others can, for example, be the return type but none of the argument types of some of the methods. The GHC Users Guide has a Functional Dependencies section.
Command line option parsers - HaskellWiki
There are several packages that want to simplify the task of writing command line parsers. Unfortunately, they are distributed across several Hackage categories. Here is an attempt to list them. Based on Hackage downloads, as of May 2017, cmdargs (126k downloads) and optparse-applicative (120k downloads) are the most popular. (Still true as of Oct 2021.) Package Multi-mode Extensions Maintenance P
Pronunciation - HaskellWiki
There was a thread on Haskell-Cafe about how to pronounce Haskell. Below are some notes for beginners on how to pronounce those strange Haskell operators and 'read' Haskell programs. This is meant to be a table with formal and informal ways of saying various operators and code snippets. Symbol Pronunciation References

Ninety-Nine Haskell Problems
These are Haskell translations of Ninety-Nine Lisp Problems, which are themselves translations of Ninety-Nine Prolog Problems. If you want to work on one of these, put your name in the block so we know someone's working on it. Then, change n in your block to the appropriate problem number, and fill in the <Problem description>,<example in Haskell>,<solution in haskell> and <description of implemen
Hoogle(the Haskell API Search Engine)
Welcome to Hoogle Links Haskell.org Hackage GHC Manual Libraries Hoogle is a Haskell API search engine, which allows you to search the Haskell libraries on Stackage by either function name, or by approximate type signature. Example searches: map (a -> b) -> [a] -> [b] Ord a => [a] -> [a] Data.Set.insert +bytestring concat Enter your own search at the top of the page. The Hoogle manual contains mor
