This is the file NEWS for the flex package. It records user -visible changes between releases of flex. See the file COPYING for copying conditions. * version 2.6.1 released 2016-03-01 ** flex resources *** The flex project is now hosted at github. Consider this a "period of transition". In particular, you should start at https://github.com/westes/flex for the flex codebase, issue tracking and pull requests. *** New releases of flex are to be found at https://github.com/westes/flex/releases. ** flex internals *** Flex now uses more modern and more standard names for variable types. There's more work to be done on that front yet, though. *** A number of compiler warnings have been remedied. *** Line directives should now work as expected and be absent when that is expected. ** test suite *** When running the test suite, c++ files are compiled with the c++ header inside the flex distribution, rather than relying on the build system's flex header , which might not be installed yet or which might be out of date with respect to what flex tests expect. *** Some portability fixes in the test suite such as opening files for reading in binary mode ** Building flex *** The file src/scan.c asdistributed with flex source is now built with the current version of flex. Occasionally this had to be done manually to pick up new flex features. It's now just a part of flex's build system. *** The pdf version of the manual is no longer distributed with flex, although if you have the texinfo package installed, you can still build it. *** lots of general build system cleanup *** the build system tries a bit harder to find libtoolize and texi2dvi. *** When help2man and texi2dvi are missing, the error messages are now much more helpful. ** bug fixes *** resolved github issues #53, #54, #55, #61. *** Resolved sf bugs #128, #129, #155, #160, #184, #187, #195. * version 2.6.0 released 2015-11-17 ** User Visible Changes *** C++ scanners now use references instead of pointers. See the manual for details. *** A number of compiler warnings were addressed, so flex generated scanners should be quieter under compiler warning scenarios. *** Allow error reporting routines to accept varying number of arguments *** Removed deprecated 'register' storage class specifier *** Changeed output formats from octal to hexadecimal *** check limits before using array index cclp; resolves sf-166 *** Suppress clang warning about empty @param paragraph; resolves sf#158 *** Fixed malloc/realloc replacement, resolves sf bug#151. *** Adjusted buffer sizes on ia64. *** various documentation and code clean up fixes: resolves sf bugs #167, #168, among other patches. ** Flex Internals *** flex is now organized into subdirectories. This keeps the tree neater at the top level and puts like things near each other and unlike things away from each other. *** The test suite has been reorganized and is now run with the parallel test suite harness from automake. *** Cleaned up the automake parts of the build system to better reflect what automake does on its own. Also added a call to libtoolize in autogen.sh because autoreconf gets confused without a prior run of libtoolize. *** po/Makefile now includes a rule to fetch the latest translations from the translation project. "make -f po/Makefile getpo" from the top level of the flex tree will fetch the files. *** New da translation from the translation project * flex version 2.5.39 released 2014-03-26 ** no user visible changes in this release * version 2.5.38 released 2014-02-14 ** internationalization *** add sr translation from the translation project *** update da, es, ko, nl, pt_BR, ro, ru, sv, tr, vi, zh_CN translations from the translation project *** rename zh_tw to its proper zh_TW name * version 2.5.37 released 2012-08-03 ** Import flex into git. See git://flex.git.sourceforge.net/gitroot/flex/flex. ** Fix make install target to not fail when the flex++ program is already installed ** New translations from the translation project: de, fi, pl, vi * version 2.5.36 released 2012-07-20 ** various portability fixes that quiet compiler warnings on 64-bit hosts ** various manual fixes, including correcting the name of a %option and updating some simple examples to use ANSI C syntax ** various bug fixes that prevent certain error conditions from persisting when they should not persist ** improvements to the test suite so it behaves better when linking compiled files ** new translations from the translation project: ca, da, es, fi, fr, ga, ko, pt_br, ro, ru, sv, tr, zh_cn ** the flex distribution is now built with automake 1.10.1 and automake 2.61 * version 2.5.35 released 2008-02-26 ** fixed bug that prevented flex from accepting certain comments in the scanner file (resolves bugs #1849809 and #1849805) ** fix bug that prevented headers for all functions from being generated (resolves bug #1628314) ** change yy_size_t to be size_t (resolves bug #1849812) ** new de, nl, pl, pt_br, vi translations from the translation project * version 2.5.34 released 2007-12-12 ** introduce yylex_init_extra; see the manual for details ** introduce %option extra-type="your_type *" (resolves bug #1744505) ** The flex program now parses multiple short concatenated options (resolves bug #1619820). Thanks to Petr Machata of Red Hat on this issue. ** better checking after yyalloc/yyrealloc (resolves bug #1595967) ** flex now provides for a libfl_pic.a compiled with position independent code. Particularly useful when including a flex scanner in a shared library and with more recent versions of gcc. Thanks to the Debian project for the idea. ** SourceForge feature request #1658379: Expose YY_BUF_SIZE in the header file. ** flex better escapes filenames with special characters in them (resolves bug #1623600) ** a memory leak was plugged(resolves bug #1601111) ** pattern language expanded; see the manual for details on the below highlights *** pattern options added to specify patterns as case-insensitive or case-sensitive *** pattern options to specify whether the "." character should match the newline character *** pattern options added to allow ignoring of whitespace in patterns *** POSIX character classes may be negated in patterns *** patterns may now use set difference, union operators ** the manual now contains an appendix listing various common patterns which may be useful when writing scanners ** some memory leaks were removed from the C++ scanner (but the C++ scanner is still experimental and may change radically without notice) ** c++ scanners can now use yywrap ** added new unit test for c++ and yywrap ** portability fixes to some unit tests ** flex man page and flex manual in pdf now distributed in the flex distribution ** new ca, vi, ga, nl translations from the translation project ** flex no longer comes with an rpm spec file ** flex development now happens with automake 1.9.6 * version 2.5.33 released 2006-2-20 ** all flex resources are now to be found from the website at http://flex.sourceforge.net/ ** there was no release 2.5.32 published ** numerous bug and security fixes ** new nl, vi, sv, ro, po, ga, ca, fr, tr translations from the translation project ** upgrade to use gettext 0.12 (this now makes the "pdf" and "ps" targets in the build system able to be run successfully) * version 2.5.31 released 2003-4-1 ** remove --enable-maintainer-mode configure option; none of the Makefiles were using it and it can be unduely confusing * version 2.5.30 released 2003-4-1 ** yylineno is per-buffer in reentrant scanners ** added %top directive for placing code at the top of the generated scanner; see manual for details ** flex now uses m4 to generate scanners; while this means that scanners are more readable, it means that flex requires m4 to be installed; see manual for details * version 2.5.29 released 2003-3-5 ** Automatic stack management for multiple input buffers in C and C++ scanners ** moved the flex documentation to a new doc/ subdirectory ** cleanups to the yy namespace * version 2.5.28 released 2003-2-12 ** flex is now hosted at sourceforge ** Fixed trailing slash bug in YY_INPUT macro def ** Flex now warns if always-interactive is specified with fast or full * version 2.5.27 released 2003-1-21 ** flex now works with recent bison versions ** new pt_br translation from the translation project * version 2.5.26 released 2003-1-14 ** Fixed table deserialization bug on big-endian archs. Patch sent from Bryce Nichols <bryce@bnichols.org> ** yyleng has proper declarations now; this caused flex to generate unusable scanners for some programs ** the flex distribution now includes a spec file suitable for use with rpm ** some more c++ fixes ** new es translation from the translation project ** slight tweeks to the flex_int*_t types ** flex now warns about pattern ranges that might be ambiguous when generating a case-insensitive scanner * version 2.5.25 released 2002-12-2 ** flex now uses flex_int*_t types. For C99 systems, they are just the int*_t types; for non-C99 systems, we just make some typedefs ** new pt_br translation from the translation project * version 2.5.24 released 2002-11-25 * more portability fixes ** the manual continues to be updated and edited, but it's still got a ways to go ** it is possible to have multiple c++ scanners in the same program again ** new turkish translation from the translation project * version 2.5.23 released 2002-10-21 ** more portability fixes ** the manual includes a title page and a table-of-contents when printed ** the test suite can be run with "make check" from the top-level directory ** configure now accepts the --enable-maintainer-mode option ** gettext functionality is now only available externally ** the constant FLEX_BETA is defined if flex is a beta release ** the script create-test was not included in the distribution and it should have been * version 2.5.22 released 2002-10-10 ** more portability fixes around how we get ahold of the integral types; there is a constant FLEX_NEED_INTEGRAL_TYPE_DEFINITIONS which you should define if you don't have the <inttypes.h> header file (after you complain to your C vendor for not providing a reasonable C environment) ** more test suite cleanups; in particular, the test suite should run correctly when build from a different directory ** upgraded automake to 1.7 and consequently autoconf to 2.54; this means, among other things, that there is some support for formatting the manual in postscript and pdf in the distributed Makefile.in (and therefore in the Makefile built by configure) ** the flex.1 manpage is generated by help2man; (this has been true for quite a while but was not listed here) ** flex now includes three defined constants to indicate which version of flex generated a scanner (YY_FLEX_{MAJOR,MINOR,SUBMINOR}_VERSION) ** flex tries its best to output only the relevant portions of the skeleton when generating a scanner, thus avoiding as much conditional compilation as possible * version 2.5.21 released 2002-9-17 ** one of the tests in the test suite broke the dist target * version 2.5.20 released 2002-9-16 ** A flex scanner has the ability to save the DFA tables to a file, and load them at runtime when needed; see the manual for details ** Added %option bison-bridge (--bison-bridge) ** Removed %option reentrant-bison/--reentrant-bison/-Rb ** yylineno is present in all scanners; Modified nasty performance penalty warning with yylineno in documentation ** test-table-opts is now run last in the test suite because it's so fat ** flex can, to some extent, diagnose where internal problems occur ** new translations from the translation project: fr, ca, de, ru, sv **Flex generates C99 defs now; see YY_TRADITIONAL_FUNC_DEFS in the manual if that's not a good thing for you * version 2.5.19 released 2002-9-5 ** prevent segfault on input lines which are longer than the allocated space (problem report from Manoj Srivastava <srivasta@golden-gryphon.com>) ** Changed option 'header' to 'header-file' * version 2.5.18 released 2002-9-4 ** portability fixes for integer constants and in the way the test suite reports its results ** the test for bison was reporting bison missing when it was, in fact, found ** if we don't find GNU indent, we're more careful when we're not finding it * version 2.5.17 released 2002-8-29 ** more portability fixes ** updated config.sub and config.guess ** flex is indented by GNU indent (this was done earlier but not explicitly documented) * version 2.5.16 released 2002-8-28 ** c++ scanners compile again ** there is now an indent target in the top-level Makefile; configure checks for GNU indent which is required for proper operation of the indent target ** some more portability fixes were made ** %options and invocation sections of manual merged ** a c++ test was added to the test suite ** we're trying to clean up more files in the test suite's make clean targets * version 2.5.15 released 2002-8-21 ** reject-state buffer is now dynamically allocated and REJECT buffer variables are reentrant-safe ** manual now discusses memory usage ** skeleton now processed by m4 before mkskel.sh; (this only matters if you want to change the skeleton or if you're doing flex development) ** zh_cn translation added from translation project ** a bug that caused a segfault has now been fixed ** the test suite now respects the usual CFLAGS, etc. variables ** removed some warnings which some tests trigggered with the -s option ** the flex-generated header file now tries to be smarter about conditionally including start conditions ** tables code omitted from generated scanner when not used * version 2.5.14 released 2002-8-15 ** the tests using the reentrant c scanner as c++ were reworked slightly to be sure that the c++ was enforced ** de translation now included in the distribution ** various portability fixes regarding nls support, c++ include headers, etc. * version 2.5.13 released 2002-8-15 ** the header file output with %option header is now much smaller ** Fixed type mismatch in printf in scanner skeleton ** yylex_init now reports errors * version 2.5.12 released 2002-8-8 ** updated gettext support to 0.11.5 ** new fr translation from the translation project ** bison is no longer needed to build flex; If you are building flex from a release (i.e., not from a cvs snapshot), then you don't need to have a pre-built lex around either (unless you modify scan.l, of course); (This has been true for some time, but was not mentioned here.) * version 2.5.11 released 2002-7-31 ** Fixed bug where yyless did not consider yylineno ** the yylineno performance hit is now gone ** fixed some typos in the manual and we now include texinfo.tex in the distribution ** traditional prototypes output for C scanners, controlled by a preprocessor symbol; see documentation for details * version 2.5.10 released 2002-7-24 ** yy_globals renamed to yyscanner and yy_globals_t renamed to yy_guts_t ** added dist-bzip2 option to Makefile.am so we now produce a bzip2'd archive in addition to the standard gzip archive * version 2.5.9 ** new tests in test suite: test-mem-{nr,r}, test-posix, test-posixly-correct, test-debug-{nr,r} ** made changes to work with gcc-3.2 development code ** ability to choose which memory functions are used in flex ** new yylex_destroy() function for the non-reentrant scanner ** new handling of POSIXLY_CORRECT environment variable ** the test suite now has its copyrights explicitly described ** new ca, de, fr, ru, sv, tr translations * version 2.5.8 ** a new --posix option generates scanners with posix-style abc{1,3} compatible parsing, see manual for the screwy details * version 2.5.7 ** configure.in now includes a call to AC_PREREQ to enforce the requirement for autoconf at least 2.50 (This only effects you if you're doing flex development.) ** configure now uses autoconf's versioning information and configure --help reports the bug-reporting address for flex ** test suite now only reports success versus failure; reporting skipped is problematic under the current setup ** compilation with --disable-nls now works ** flex can now be built in a separate directory * version 2.5.6 ** gettext support added (from gettext 0.11) *** translations for ca, da, de, es, fr, ko, ru, sv, tr included ** distribution now built under automake 1.6 and autoconf 2.53 ** command-line option parsing happens differently now: *** Added long option parsing *** Options -n and -c, previously deprecated, now simply do nothing *** Options are now parsed left to right ** added a number of new options *** All positive %options are now accessible from the command line *** Added option -D, to define a preprocessor symbol *** Added option --header=FILE to specify a C .h file to generate *** added option --yywrap to call yywrap on EOF *** added option --yylineno to track line count in yylineno *** --yyclass=NAME name of C++ class when generating c++ scanners *** for long option names which are associated with existing short options, see accompanying documentation *** new %option nounistd or command-line --nounistd added to prevent flex from generating #include <unistd.h> on systems that don't have that include file ** Support for reentrant C scanners has been added *** Updated the manual with the new reentrant API *** Two new options %option reentrant (-R) and %option reentrant-bison (-Rb) *** All globals optionally placed into struct yyglobals_t *** All access to globals replaced by macro invocations *** All functions optionally take one additional argument, yy_globals *** New style for invoking reentrant scanner: yylex_init(void** scanner ); yylex( scanner ); yylex_destroy( scanner ); *** Added get/set functions for members of struct yy_globals_t e.g., yyget_text, yyget_leng, etc *** Prefix substitution added for new functions *** Macro shortcuts to the lengthy get/set functions provided for use in actions, e.g., yytext, yyleng, etc *** Arbitrary, user-defined data, "yyextra", may be added to scanner ** %option nomain no longer implies %option yywrap But the inverse is still true ** Developer test suite added *** TESTS/ directory has been added. Users can 'make test' in the TESTS directory to execute the test suite ** Support for bison variables yylval and yylloc added ** automake support for the build process ** manual is now in texinfo/info format *** flex.1 removed from distribution ** flex no longer generates C-language scanners with C++-style comments ** flex now generates scanners in c++ which are compatible with recent c++ compilers ** flex input scanner now recognizes '\r' as an EOL character See the file ONEWS for changes in earlier releases.
