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 2.5.7
** 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 check' 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.
