./devel/alex, Tool for generating lexical analysers in Haskell

[ Image CVSweb ] [ Image Homepage ] [ Image RSS ] [ Image Required by ] [ Image Add to tracker ]

Branch: CURRENT, Version: 3.5.4.2, Package name: alex-3.5.4.2, Maintainer: esg

Alex is a tool for generating lexical analysers in Haskell, given a
description of the tokens to be recognised in the form of regular
expressions. It is similar to the tools lex and flex for C/C++.

Alex takes a description of tokens based on regular expressions and
generates a Haskell module containing code for scanning text
efficiently. Alex is designed to be familiar to exisiting lex users,
although it does depart from lex in a number of ways.
