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 2.5.6
** Support for reentrant C scanners has been added.
** Developer test suite added.
** 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_r, yyleng_r, etc.
** Arbitrary, user-defined data, "yyextra", may be added to scanner.
** %option nomain no longer implies %option yywrap.
But the inverse is still true.
** 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.
** Updated the man page with the new reentrant API.
See the file ONEWS for changes in earlier releases.
