Jflex 1.5.0

Released 2014-03-23

• the "switch" and "table" code generation options are deprecated
  and will be removed in JFlex 1.6
• the JFlex license has been changed from GPL to BSD.
• 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
  Basic Unicode Support - Level 1. Supplementary code points (above
  the Basic Multilingual Plane) are not yet supported.
• new meta characters supported: \s, \S, \d, \D, \w, \W.
• nested character sets now supported, e.g. [[[ABC]D]E[FG]]
• new character set operations supported: union (e.g. [A||B]), intersection (e.g.
  [A&&B]), set-difference (e.g. [A--B]), and symmetric difference (e.g. [A~~B]).
• 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].
• new \R meta character matches any newline:
  "\r\n" | [\n\r\u000B\u000C\u0085\u2028\u2029].
• new option --noinputstreamctor to not include an InputStream
  constructor in the generated scanner.
• %include can now be used in the rules section (#117)
• yychar and zzAtBOL should be reset for nested input streams (#107 & #108 )
• fixed bug #109 (could not match input for empty string matches.)
• fixed bug #112 & #119 (properly update zzFin when reallocating zzBuffer)
• fixed bug #115 (noncompileable scanner generation when default locale is Turkish)
• fixed bug #114 (zzEOFDone not included with pushed nested stream state)
• fixed bug #105 (can't build examples/java/)
• fixed bug #106 (impossible char class range should trigger syntax error)

1.4.3

Released 2009-01-31

• fixed bug #100 (lookahead syntax error)
• fixed bug #97 (min_int in Java example scanner)
• fixed bug #96 (zzEOFDone not reset in yyreset(Reader))
• fixed bug #95 (%type and %int at the same time should produce error msg)

1.4.2

Released 2008-05-28

• implemented feature request #75:
  Now supports generics syntax for %type, %extends, etc
• implemented feature request #156:
  Provided %ctorarg option to add arguments to constructor
• fixed bug #80 (Reader.read might return 0)
• fixed bug #57 (Ambiguous error message in macro expansion)
• fixed bug #89 (Syntax error in input may cause NullPointerException)
• fixed bug #85 (Need to defend against path blanks in jflex bash script)
• fixed bug #82 (EOF actions may be ignored for same lex state)
• fixed bug #81 (syntax error in generated ZZ_CMAP)
• fixed bug #77 (lookahead and "|" actions)
• fixed bug #74 (yytext() longer than expected with lookahead)
• fixed bug #73 (OS/2 Java 1.1.8 Issues)
• fixed bug #40 (dangerous lookahead check may fail)

1.4.1

Released 2004-11-07

• merged in patch by Don Brown (fixes #70 Uses Old JUnit method assertFalse)
• merged in patch by Don Brown (fixes #62 buffer expansion bug in yy_refill())
  Thanks to Binesh Bannerjee for providing a simpler test case for this problem.
• fixed bug #69 (ArrayIndexOutOfBounds in IntCharSet)
• fixed bug #68 (Cannot use lookahead with ignorecase)
• converted dangerous lookahead error to warning
• print info for EOF actions as well in %debug mode
• fixed line number count for EOF actions
• internal: removed unused methods in LexScan.flex and IntCharSet

1.4

Released 2004-04-12

• new, very fast minimization algorithm (also fixes memory issues)
• new --jlex option for strict compatibility to JLex. Currently it
  changes %ignorecase to JLex semantics, that is, character classes
  are interpreted in a caseless way, too.
  (fixes bus #59, %ignorecase ignored by char classes).
  Thanks to Edward D. Willink for spotting the incompatibility.
• support for even larger scanners (up to 64K DFA states).
  Thanks to Karin Vespoor.
• removed eclipse compiler warnings for generated classes
  (feature request #144)
• implemented faster character classes (feature request #143).
  Expressions like [a-z] | [A-Z] are interpreted as one atomic class
  [a-zA-Z], reducing NFA states and generation time significantly
  for some specifications. This affects the generation process only,
  generated scanners remain the same.
• new %apiprivate switch (feature request #141/1) that causes all
  generated and skeleton methods to be made private. Exceptions to this
  are user defined functions and the constructor. Thanks to Stephen
  Ostermiller for the suggestion.
• allow user defined javadoc class comments (feature request #141/2)
  If the user code section ends with a javadoc comment, JFlex takes this
  instead of the generated comment. Thanks to Stephen Ostermiller for
  the suggestion.
• fixed bug #50 (undefined macros in complement expressions do
  not throw exception in generator). Thanks to Stephen Ostermiller
  for the bug report.
• fixed bug #51 (yypushStream/yypopStream in skeleton.nested
  work as advertised)
• fixed bug #57 (no wrong macro warnings on regexp negation)
• fixed bug #58 (%cupsym now also affects %cupdebug)
  Thanks to Eric Schweitz for the fix.
• fixed bug #52 (single-line %initthrow works now
  in case of extra whitespace before newline)
• yyreset() does no longer close the associated reader (use yyclose()
  explicitly for that). Makes some reader objects reusable (feature
  request #140). Thanks to Stephen Ostermiller for the suggestion.
• fixed modifier order in generated code, removes jikes compiler warnings
  Thanks to Michael Wildpaner for the fix.
• ant task now also works with ant >= 1.4 (fixes bug #54)
• yyreset() does not declare an execption any more (fixes bug #65)
• %cup does not include %eofclose in JLex mode (--jlex). (Fixes bug #63)
• optional parameter to %eofclose: "%eofclose false" turns off %eofclose if
  it was turned on previously (e.g. by %cup). (Fixes bug #63)
• jflex build script switched to ant
• internal: central Options class for better integration with
  build tools and IDEs
• internal: change naming scheme for generated internal variables from
  yy_ to zz to comply with Java naming standard. Thanks to Max Gilead
  for the patch.
