This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.
Alex is a tool for generating lexical analysers in Haskell. It takes a description of tokens based on regular expressions and generates a Haskell module containing code for scanning text efficiently. It is similar to the tool lex or flex for C/C++.

[back to package description]Alex: A Lexical Analyser Generator
Alex is a tool for generating lexical analysers, also known as "lexers" and "scanners", in Haskell. The lexical analysers implement 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++.
