Happy (software)
Encyclopedia
Happy is a parser generator written in Haskell
. It produces haskell-code and optionally optimized code for Glasgow Haskell Compiler
and it's extensions. Happy is contained (along with Alex, a lexer-generator
) in the Haskell Platform
. It is available for Unix-like systems, such as Mac OS X, Linux and BSDish systems and Windows.
Haskell (programming language)
Haskell is a standardized, general-purpose purely functional programming language, with non-strict semantics and strong static typing. It is named after logician Haskell Curry. In Haskell, "a function is a first-class citizen" of the programming language. As a functional programming language, the...

Lexical analysis
In computer science, lexical analysis is the process of converting a sequence of characters into a sequence of tokens. A program or function which performs lexical analysis is called a lexical analyzer, lexer or scanner...

Haskell Platform
The Haskell Platform is a collection of software-packages, tools and libraries, which is to create a common platform for using and developing applications in Haskell. With the Haskell Platform, Haskell follows the same principle as Python: "Batteries included"...
