Released 2015-03-16

1.6.1 is a maintenance release, fixing all known defects.

Changelog:

  • JFlex development, wiki, and issue tracker moved to https://github.com/jflex-de/
  • Fixed issue #130, "in caseless mode, chars in regexps not accepted caselessly":
    Caseless option works again as intended.
  • Fixed issue #131, "re-enable scanning interactively or from a network byte stream":
    JFlex now throws an IOException when a Reader returns 0 characters.
  • New example, shows how to deal with Readers that return 0 characters.
  • Command line scripts work again in repository version (contributed by Emma Strubell)
  • New options --warn-unused and --no-warn-unused that control warnings about unused macros.
  • Fixed issue #125: %apiprivate and %cup2 switches now no longer incompatible
  • Fix issue #133, "Error in skeleton.nested":
    Empty-string matches were taking precedence over EOF and caused non-termination.
    Now EOF is counted as the highest-priority empty match.
  • New warning when an expression matches the empty string (can lead to non-termination).

Released 2014-06-21

  • Unicode 7.0 is supported.
  • In %unicode mode, supplementary code points are now handled properly.
    • Regular expressions are now code-point based, rather than code-unit/
      char based.
    • Input streams are read as code point sequences - properly paired
      surrogate code units are read as a single character.
    • All supported Unicode properties now match supplementary characters
      when Unicode 3.0 or above is specified, or when no version is
      specified, causing the default Unicode version, Unicode 7.0 in this
      release, to be used.
  • New \u{...} escape sequence allows code points (and whitespace-separated
    sequences of code points) to be specified as 1-6 hexadecimal digit values.
  • Characters in matches printed in %debug mode are now Unicode escaped
    (\uXXXX) when they are outside the range 32..127.
  • detect javadoc class comment when followed by annotation(s) (#128)
  • removed the "switch" and "table" code generation options
  • Option --noinputstreamctor deprecated.
    By default no InputStream constructor is included in the generated
    scanner. The capability to include one is deprecated and will be
    removed in JFlex 1.7.

  • updated JFlex to CUP version 0.11a.
  • changed the build from Ant to Maven. 523d7a9
  • JFlex now mostly conforms with Unicode Regular Expressions UTS#18

  • the meaning of the dot (".") meta character has been changed from [^\n] to
    [^\n\r\u000B\u000C\u0085\u2028\u2029]. Use the new --legacydot option to
    cause "." to be interpreted as [^\n].

    "\r\n" | [\n\r\u000B\u000C\u0085\u2028\u2029].
