Difference between revisions of "Learning Haskell"

Revision as of 13:11, 14 December 2007

This portal points to places where you can go if you want to learn Haskell.

The Introduction to Haskell on the Haskell website tells you what Haskell gives you: substantially increased programmer productivity, shorter, clearer, and more maintainable code, fewer errors, higher reliability, a smaller semantic gap between the programmer and the language, shorter lead times. There is an old but still relevant paper about Why Functional Programming Matters by John Hughes. More recently, Sebastian Sylvan wrote an article about Why Haskell Matters.

There is also a table comparing Haskell to other functional languages. Many questions about functional programming are answered by the comp.lang.functional FAQ.

Implementations

Here is an overview about Haskell implementations:

	Messages	Size	Tools	Remarks
Hugs	+/-	++	-	Fast compilation; used a lot for learning Haskell and rapid code development. See also WinHugs.
GHC	+	-	++	Many language extensions; generated code is very fast. The most popular implementation.
NHC	?	+	++	Profiling, debugging, tracing
Yhc	?	+	?	Compiles to bytecodes. Runtime easily portable. Still under heavy development.
Helium	++	++	-	No type classes (yet!) and thus incompatible with most material on this site. Made for teaching/learning.

Detailed information on the implementations can be found in a separate article.
