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

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

Branch: CURRENT, Version: 3.5.1.0nb1, Package name: alex-3.5.1.0nb1, 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.

Log message:
alex: update to 3.5.1.0.

## Changes in 3.5.1.0

* Drop generating output for GHC < 6.4.
* Use qualified imports in generated code (except for `Prelude`)
  ([Issue #258](https://github.com/haskell/alex/issues/258)).
* Suppress warnings `tabs` and `unused-imports` for generated code
  ([Issue #255](https://github.com/haskell/alex/issues/255)).
* Tested with GHC 8.0 - 9.8.2.

## Changes in 3.5.0.0

 * Add option `--numeric-version`.
 * Remove deprecated `-v` as alias for `--version`.
 * Add `-v` as placeholder for a future `--verbose` option.
 * Make `alex{G,S}etUserState` available with the `monadUserState-bytestring` wrapper
   ([Issue #220](https://github.com/haskell/alex/issues/220)).
 * Debugging lexer: print character in addition to its ASCII code
   ([PR #252](https://github.com/haskell/alex/pull/252)).
 * Tested with GHC 8.0 - 9.8.1.

Log message:
devel/alex: Update to 3.4.0.0

Changes in 3.4.0.0 [Andreas Abel, 2023-06-20]
* New wrappers to lex strict Text: strict-text, posn-strict-text,
  monad-strict-text and monadUserState-strict-text (PR #240). These
  complement the existing wrappers for String and ByteString.
* Tested with GHC 7.0 - 9.6.2.

Changes in 3.3.0.0 [Andreas Abel, 2023-05-25]
* Add an Ord instance to AlexPosn (Issue #233). This breaks developments
  that define their own (orphan) instance Ord AlexPosn. If this is the
  derived stock instance, the fix is to delete the orphan instance and
  require build-tool-depends: alex:alex >= 3.3.0.0.
* Switch to Haskell PVP versioning with four digits.
* Tested with GHC 7.0 - 9.6.1.

Change in 3.2.7.4 [Andreas Abel, 2023-05-02]
* The user-supplied "epilogue" Haskell code is now put last in the
  generated file. This enables use of Template Haskell in the
  epilogue. (Issue #125.)
* Tested with GHC 7.0 - 9.6.1.

Change in 3.2.7.3 [Andreas Abel, 2023-04-14]
* Amend last change (3.2.7.2) so that Alex-generated code does not need
  LANGUAGE PatternGuards.
* Tested with GHC 7.0 - 9.6.1.

Change in 3.2.7.2 [Andreas Abel, 2023-04-03]
* Fix bug with out-of-bound access to alex_check array. (Surfaced with
  GHC's JS backend, fixed by Sylvain Henry in PR #223.)
* Tested with GHC 7.0 - 9.6.1.

Bump Haskell packages after updating lang/ghc94
   2023-06-06 14:42:56 by Taylor R Campbell | Files touched by this commit (1319) 
Log message:
Mass-change BUILD_DEPENDS to TOOL_DEPENDS outside mk/.

Almost all uses, if not all of them, are wrong, according to the
semantics of BUILD_DEPENDS (packages built for target available for
use _by_ tools at build-time) and TOOL_DEPEPNDS (packages built for
host available for use _as_ tools at build-time).

No change to BUILD_DEPENDS as used correctly inside buildlink3.

Log message:
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.
