Alex: A Lexical Analyser Generator
Alex is a Lex-like tool for generating Haskell scanners. For complete
documentation, see the doc directory.
http://www.haskell.org/alex/
http://hackage.haskell.org/cgi-bin/hackage-scripts/package/alex
Alex is built using Cabal. First install GHC, then:
$ runhaskell Setup.lhs configure
$ runhaskell Setup.lhs build
$ runhaskell Setup.lhs install
Alex version 2.0 has changed fairly considerably since version 1.x,
and the syntax is almost completely different. For a detailed list of
changes, see the release notes in the documentation.
Alex is now covered by a BSD-Style licence; see the licence file in
the `doc' directory for details.
The sources are in the the `src' directory and the documentation in the `doc'
directory; various examples are in the 'examples' subdirectory.
The source code in the 'src' and 'examples' directories is intended
for a Haskell 98 compiler with hierarchical modules. It should work
with GHC >= 5.04.
Please report any bugs or comments to the email addresses given below.
