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

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

Branch: CURRENT, Version: 3.2.7.1nb3, Package name: alex-3.2.7.1nb3, 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.

Update to alex-3.2.7.1

Change in 3.2.7.1
* Fix bug with repeated numeral characters outside of r{n,m}
  repetitions. This was a regression introduced in 3.2.7.

Changes in 3.2.7
* Allow arbitrary repetitions in regexps. Previously, the r{n,m} and
  related forms were restricted to single digit numbers n and m.
* DFA minimization used to crash on tokens of the form c* which produce
  automata with only accepting states. Considering the empty set of
  non-accepting states as an equivalence class caused minimization to crash
  with exception.
* The small_base flag is removed. Extremely old GHCs will no longer build.
* A number of bug fixes and clearer diagnostics.
