| 23 | * JFlex 1.4.1 (November 7, 2004)
|
|---|
| 24 | - merged in patch by Don Brown (fixes #1049791 Uses Old JUnit method assertFalse)
|
|---|

| 34 | * JFlex 1.4 (April 12, 2004)
|
|---|
| 35 | - new, very fast minimization algorithm (also fixes memory issues)
|
|---|
| 36 | - new --jlex option for strict compatibility to JLex. Currently it
|
|---|
| 37 | changes %ignorecase to JLex semantics, that is, character classes
|
|---|
| 38 | are interpreted in a caseless way, too.
|
|---|
| 39 | (fixes bus #751757, %ignorecase ignored by char classes).
|
|---|
| 40 | Thanks to Edward D. Willink for spotting the incompatibility.
|
|---|
| 41 | - support for even larger scanners (up to 64K DFA states).
|
|---|
| 42 | Thanks to Karin Vespoor.
|
|---|
| 43 | - removed eclipse compiler warnings for generated classes
|
|---|
| 44 | (feature request #778747)
|
|---|
| 45 | - implemented faster character classes (feature request #604589).
|
|---|
| 46 | Expressions like [a-z] | [A-Z] are interpreted as one atomic class
|
|---|
| 47 | [a-zA-Z], reducing NFA states and generation time significantly
|
|---|
| 48 | for some specifications. This affects the generation process only,
|
|---|
| 49 | generated scanners remain the same.
|
|---|
| 50 | - new %apiprivate switch (feature request #513500/1) that causes all
|
|---|
| 51 | generated and skeleton methods to be made private. Exceptions to this
|
|---|
| 52 | are user defined functions and the constructor. Thanks to Stephen
|
|---|
| 53 | Ostermiller for the suggestion.
|
|---|
| 54 | - allow user defined javadoc class comments (feature request #513500/2)
|
|---|
| 55 | If the user code section ends with a javadoc comment, JFlex takes this
|
|---|
| 56 | instead of the generated comment. Thanks to Stephen Ostermiller for
|
|---|
| 57 | the suggestion.
|
|---|
| 58 | - fixed bug #491095 (undefined macros in complement expressions do
|
|---|
| 59 | not throw exception in generator). Thanks to Stephen Ostermiller
|
|---|
| 60 | for the bug report.
|
|---|
| 61 | - fixed bug #495422 (yypushStream/yypopStream in skeleton.nested
|
|---|
| 62 | work as advertised)
|
|---|
| 63 | - fixed bug #611118 (no wrong macro warnings on regexp negation)
|
|---|
| 64 | - fixed bug #655528 (%cupsym now also affects %cupdebug)
|
|---|
| 65 | Thanks to Eric Schweitz for the fix.
|
|---|
| 66 | - fixed bug #510010 (single-line %initthrow works now
|
|---|
| 67 | in case of extra whitespace before newline)
|
|---|
| 68 | - yyreset() does no longer close the associated reader (use yyclose()
|
|---|
| 69 | explicitly for that). Makes some reader objects reusable (feature
|
|---|
| 70 | request #513492). Thanks to Stephen Ostermiller for the suggestion.
|
|---|
| 71 | - fixed modifier order in generated code, removes jikes compiler warnings
|
|---|
| 72 | Thanks to Michael Wildpaner for the fix.
|
|---|
| 73 | - ant task now also works with ant >= 1.4 (fixes bug #526905)
|
|---|
| 74 | - yyreset() does not declare an execption any more (fixes bug #913132)
|
|---|
| 75 | - %cup does not include %eofclose in JLex mode (--jlex). (Fixes bug #910562)
|
|---|
| 76 | - optional parameter to %eofclose: "%eofclose false" turns off %eofclose if
|
|---|
| 77 | it was turned on previously (e.g. by %cup). (Fixes bug #910562)
|
|---|
| 78 | - jflex build script switched to ant
|
|---|
| 79 | - internal: central Options class for better integration with
|
|---|
| 80 | build tools and IDEs
|
|---|
| 81 | - internal: change naming scheme for generated internal variables from
|
|---|
| 82 | yy_ to zz to comply with Java naming standard. Thanks to Max Gilead
|
|---|
| 83 | for the patch.
|
|---|

|
|---|
| 103 | - fixed all reported bugs except #39 (lookahead check at generation
|
|---|
| 104 | time may fail). Thanks to Axel Schwolow, Karl Meissner, Angelo
|
|---|
| 105 | Borsotti, and Paolo Di Francesco for their excellent bug reports.
|
|---|
| 106 | - enhanced %debug output. JFlex scanners in debug mode now print line,
|
|---|
| 107 | column, matched text, and executed action (with line number in spec)
|
|---|
| 108 | for each processed token. Thanks to
|
|---|
| 109 | <a href="http://meissner.v0.net/msd.htm">Karl Meissner</a> for the
|
|---|
| 110 | suggestion.
|
|---|
| 111 | - introduced %cupdebug directive for readable CUP debugging. Generated
|
|---|
| 112 | scanners print line, column, matched text, and CUP symbol name for
|
|---|
| 113 | each returned token. Again thanks to Karl Meissner for tips and
|
|---|
| 114 | contributed Java reflection code.
|

|
|---|
| 118 | - code generation now customizable at command line with --table,
|
|---|
| 119 | --pack, and --switch
|
|---|
| 120 | - command line switch --info prints system and JVM information (useful
|
|---|
| 121 | for bug reports)
|
|---|
| 122 | - command line switch --nobak for not generating backup files
|
|---|
| 123 | - an Ant task for the Ant build tool http://jakarta.apache.org/ant/
|
|---|
| 124 | contributed by Rafal Mantiuk. Many thanks to him.
|
|---|
| 125 | - better error message for missing ] in char class. Thanks to Karl
|
|---|
| 126 | Meissner.
|
|---|
| 127 | - performance enhancements in the runtime system. The engine is now
|
|---|
| 128 | 10%-50% faster. These are only the first implementations of a few of
|
|---|
| 129 | the many suggestions from Angelo Borsotti. Thanks to Angelo for many
|
|---|
| 130 | insights, tips, and fruitful discussions.
|
|---|
| 131 | - a new warning if a rule can never be matched
|
|---|
| 132 | - macros and regular expression can now span multiple lines (note
|
|---|
| 133 | that <tt>|</tt> at the end of a line in a rule is a special action,
|
|---|
| 134 | not the <tt>|</tt> operator)
|
|---|
| 135 | - updated the manual to contain more information about the generated
|
|---|
| 136 | class, clarified the description of lexical states. Thanks to Michael
|
|---|
| 137 | Binz, Angelo Borsotti, Vasily Karyaev and for the suggestions.
|
|---|
| 138 | - Simplified java example lexer, and allow // style comments at EOF.
|

|---|
| 144 |
|
|---|
| 145 | * JFlex 1.3.2 (February 24, 2001)
|
|---|
| 146 | - fixed bug #32 (this time for real). Thanks to Thilo Goetz for
|
|---|
| 147 | his quick report.
|
|---|
| 148 | - updated the binary scanning example with the more comprehensive and
|
|---|
| 149 | usable class StraightStreamReader by Stephen Ostermiller. Thanks go to
|
|---|
| 150 | him for his contribution. The original version of this class is at
|
|---|
| 151 | http://www.smo.f2s.com/utils/
|
|---|
| 152 | - added a link to a Japanese translation of the JFlex manual (it's in Japanese
|
|---|
| 153 | Shift_JIS encoding). The translation is for an older release (1.1.2), but
|
|---|
| 154 | most of the text still applies to the current version. See the change log
|
|---|
| 155 | for the differences between 1.1.2 and the current version. Many thanks to
|
|---|
| 156 | Yuichi Nakajima, Yukio Ikeda, Katsuhiko Yamazaki, and Koji Ooya for
|
|---|
| 157 | their efforts.
|
|---|
| 158 | If you would like to translate the JFlex manual into another language, or
|
|---|
| 159 | if you already have done so, please let me know. I will include a link to
|
|---|
| 160 | it on the documentation page. I can also give you access to the latex
|
|---|
| 161 | sources of the manual, so that printable versions of your translation can
|
|---|
| 162 | be generated, too.
|
|---|
| 163 |

|
|---|
| 178 | - switch for skipping the minimization step in DFA generation (--nomin).
|
|---|
| 179 | This feature is still in alpha status and not yet extensively tested. It
|
|---|
| 180 | might be useful when you have very large scanners and not much memory
|
|---|
| 181 | available.
|
|---|
| 182 | - switch for generating graphviz dot files for graphical representation (ps
|
|---|
| 183 | or gif) of generated NFA, DFA and minimized DFA (--dot). Might be useful for
|
|---|
| 184 | teaching. This feature is also still in alpha status and not fully finished
|
|---|
| 185 | yet. It is included as preview, comments are welcome, please try it out and
|
|---|
| 186 | tell me what you think. For information on graphviz see
