|
|
|
|
* version 2.5.31 released 2003-4-1
|

|
|
* 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
|

ways to go

|

|
|
* 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)
|

|
|
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
|
|
|
|

|

|
|
|
|
** 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
|
|

** 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
|
|
|
|

|
|
finding it

|
|

|
|
** c++ scanners compile again

|
|
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
|
|
|
|

|
|
|
** 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.)
|
|
|

|
|
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
|
|

|
|
|
|
** 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
|
|
|
|

|
|
|

|
|
|

|
|
*** added option --yylineno to track line count in yylineno
|
|
|

|
|
|
|
*** 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

|
|
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
