  • v1.6.1 Changes

    November 09, 2017

    ๐Ÿš€ 1.6.1 is a maintenance release, fixing all known defects.

    ๐Ÿ”„ Changelog:

    • ๐Ÿšš JFlex development, wiki, and issue tracker moved to https://github.com/jflex-de/
    • ๐Ÿ›  Fixed issue #130, "in caseless mode, chars in regexps not accepted caselessly":
      Caseless option works again as intended.
    • ๐Ÿ›  Fixed issue #131, "re-enable scanning interactively or from a network byte stream":
      JFlex now throws an IOException when a Reader returns 0 characters.
    • ๐Ÿ†• New example, shows how to deal with Readers that return 0 characters.
    • ๐Ÿ’ป Command line scripts work again in repository version (contributed by Emma Strubell)
    • ๐Ÿ†• New options --warn-unused and --no-warn-unused that control warnings about unused macros.
    • ๐Ÿ›  Fixed issue #125: %apiprivate and %cup2 switches now no longer incompatible
    • ๐Ÿ›  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.
    • ๐Ÿ†• New warning when an expression matches the empty string (can lead to non-termination).
  • v1.6.0 Changes

    November 09, 2017
    • ๐Ÿ‘ 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
        0๏ธโƒฃ specified, causing the default Unicode version, Unicode 7.0 in this
        ๐Ÿš€ release, to be used.
    • ๐Ÿ†• New \u{...} escape sequence allows code points (and whitespace-separated
      sequences of code points) to be specified as 1-6 hexadecimal digit values.
    • ๐Ÿ–จ 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)
    • โœ‚ removed the "switch" and "table" code generation options
    • ๐Ÿ—„ Option --noinputstreamctor deprecated.
      0๏ธโƒฃ By default no InputStream constructor is included in the generated
      ๐Ÿ—„ scanner. The capability to include one is deprecated and will be
      โœ‚ removed in JFlex 1.7.
