These are a few examples of Happy parsers, taken from various sources.
The are intended as illustrations, not as working, complete examples,
as some require functions and datatypes imported from other sources.
Calc.ly : The calculator example from the Happy manual
DavesExample.ly : Parses simple lambda expressions to combinators
SimonsExample.ly : Another lambda expression parser
ErlParser.ly : A parser for Erlang
MonadTest.ly : Demonstrates use of %monad
LexerTest.ly : Demonstrates use of %monad and %lexer
ErrorTest.ly : Demonstrates use of the 'error' token
There are also a few more examples under happy/tests.
A full Haskell 98 parser written using Happy is available from the GHC
CVS repository in fptools/hslibs/hssource. See
http://www.haskell.org/ghc/ for instructions on how to access the GHC
CVS repository.
