JFlex 1.6.1 发布，次版本主要有以下更新： 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). 详细信息请查阅发行页面。 下载地址如下： http://www.jflex.de/download.html JFlex 是一个 Java 的词法/语法分析生成器。 JFlex 1.6.1 发布，语法分析生成器下载地址
