+ added hb_gcFunc(), hb_parptrGC(), hb_itemGetPtrGC()
hb_parptrGC() and hb_itemGetPtrGC() uses GC cleanup function address
to validate if pointer item points to expected memory block type

to PP structure
+ harbour/include/hbregex.h
+ harbour/source/rtl/hbregex.c
* harbour/source/rtl/Makefile
* harbour/common.mak
+ added support for regular expressions. Now it's enabled by default
only in *nixes (POSIX regex) and BCC 5.5 (PCRE regex). Setting
HB_PCRE_REGEX macro enables Perl-Compatible Regular Expressions
and HB_POSIX_REGEX - POSIX regular expressions. In xHarbour regex
support is enabled for all builds because PCRE source code is stored
in CVS. If you will want we can make the same.
+ the following C functions are available:
hb_regexCompile(), hb_regexGet(), hb_regexFree(), hb_regexMatch()
+ the following PGR functions are available:
HB_REGEXCOMP(), HB_ISREGEX(), HB_ATX(), HB_REGEX(), HB_REGEXMATCH(),
HB_REGEXSPLIT(), HB_REGEXATX(), HB_REGEXALL()
They are working in similar way to the ones in xHarbour with the
exception to some bug fixes and form of compiled regular expression.
In Harbour it's pointer item for which HB_ISREGEX() returns TRUE when
in xHarbour it's binary string.
* harbour/source/rdd/dbfcdx/dbfcdx1.c

(DBOI_SKIPREGEX[BACK])
* harbour/common.mak
* harbour/source/compiler/Makefile
* harbour/source/compiler/hbfix.c
+ harbour/source/compiler/hbopt.c
* divided hbfix.c into two separated functions:
- hb_compFixFuncPCode() which only fix generated PCODE updating
local parameters numbers when PARAMETERS is used
- hb_compOptimizePCode() which makes PCODE optimization
It allows to not execute hb_compFixFuncPCode() when PARAMETERS
is not use and execute hb_compOptimizePCode() more then once in
optimization process.

* harbour/source/compiler/hbgenerr.c
* harbour/source/compiler/hbident.c
* changed code for generating in PCODE line numbers and module names
there was serious problem with line numbers and module names in old
code - in many cases line numbers were not generated at all or
generated in wrong places. Also file module name was not updated
when inside of function some code was included with #include
For such situation now modified version of HB_P_MODULE is generated
with module name only but without function name, f.e.:
HB_P_MODULE "test.prg:"
exactly the same form of HB_P_MODULE is used in xHarbour.
Debugger code should be updated to recognize such HB_P_MODULE version
Ryszard any chance that you can look at it?
And what about syncing with xHarbour debugger?
I can add some missing functions to compiler and HVM but I do not
want to update next peace of code myself. Sorry but I do not have
enough time. I'd prefer to finish some other things I'm working.
If Ryszard is busy can someone else try to port xHarbour debugger
to Harbour?

These modifications should help in future compiler and macro compiler
integration into single binary.
+ added clipper compatible error message in unclosed structures
In general we should cleanup rules to make error reporting more
user friendly and Clipper compatible
% eliminated unnecessary allocations
+ added int mode member to common part of HB_COMP and HB_MACRO
structure. It's initialized to HB_MODE_MACRO or HB_MODE_COMPILER
+ add TOFIX note about memory leaks in cParamTypes and pParamClasses
members of COMDECLARED structure. It's a part of unfinished strong
typing code. I do not know what Ryszard plan to do with it so I'm
leaving it as is. The part of strong typing which were operating
on emulated HVM stack has been removed.
* removed static variables from genjava.c. Also gencli.c and genobj32.c
should be fixed but this will not make this code working so I haven't
touched it.
* changed 3-rd parameter of hb_compIdentifierNew() from BOOL to int.
Now it can have the following values: HB_IDENT_STATIC, HB_IDENT_FREE,
HB_IDENT_COPY. This modification will allow in the future using common
for static and dynamic symbol hash table without additional source code
changes. I also plan to use identifier hash table in PP the reduce
number of memory allocations and speed-up preprocessing by using
second level hashing for hash keys.
* harbour/source/common/expropt1.c

expression to HB_ET_ALIAS.
* harbour/source/macro/macro.y
! fixed using prefix¯o-> and ¯o.sufix-> when macro cannot be
substituted by compiler, f.e.:
M->v := NIL
x := "&v.1->fld"
M->v := "v"
M->v1:= "data"
? &x
! fixed memory leak in macro substituted expression compilation
* harbour/source/vm/macro.c

* changed the internal compiler API to be MT safe.
All global and static non constant variables replaced by
HB_COMP structure which have all compiler context settings.
It's possible to allocate simultaneously many compiler contexts
and compile code. Only constant/read only variables are shared.
In macro compiler HB_COMP is replaced by HB_MACRO.
In source code I everywhere used to macros: HB_COMP_DECL and
HB_COMP_PARAM which are equivalents of old HB_MACRO_DECL and
HB_MACRO_PARAM definitions.
We will only have to change compiler FATAL errors support to
not execute exit() for non batch systems.
* make macro compiler fully MT safe
* removed not longer used definitions and variables
! add direct accessing to PP line number information - it fixes missing
line numbers reported recently
! added generating .ppo files when tokens are teken directly by compiler
- it fixes empty .ppo file problem
! clear hb_stack internall variables after removing hb_stack to avoid
possible GPF if application still works and try to access unexsiting
hb_stack
! do not allocate new memory block when final FM statistic report is
generated - it fixes problem with GPF when application compiled with
FM statistic exits and CLIPPER envvar is set.
! fixed memory leak hb_cmdargCheck()
! added to harbour.y symbol destructors - it should fixes memory leaks
in syntax errors but it uses quite new bison feature which is not
fully supported yet. Unfortunately it's also not MT safe and the
destructors implementation in 1.875c does not respect %parse-param.
Bison documentation says that it should so I hope it will be fixed
soon (or maybe even already is in the newest bison versions) before
I'll add multi context compilation support. If not then I will have
to add some workaround. I can pass compiler context pointer inside
YYSTYPE using hack in a lexer but it will force really huge number
modifications in existing bison rules so probably it will be much
easier to fix bison or write a small tool to update generated parser.

* updated to compile with recent compiler header file modifications
PP, new lexer and most of grammar parser should be MT safe. Now we should
update all compiler functions to pass pointer to HB_COMP data structure
where we should all current global variables. This structure as first
member should have HB_CMPCOMMON structure which will hold common to
compiler and macro compiler data. Ryszard I think you are the best person
to define this structure.
We have new lexer which is MT safe but please note that it has to be
extensively tested so I would like to ask everybody to compile as much
as possible different code and check if the final programs work as
expected. Working on new code I removed some limitations existing in
FLEX though not all. At the beginning I tried to replicate the exact
FLEX behavior but I've found that in few places it does not work as
it should so I begin to encode rules in a way which remove some
limitations. In fact now it's much easier to control some things.
I kept the FLEX code working and made all necessary modifications
so it still can be used but keeping FLEX working cost us IMHO too
much. It's not possible to introduce some improvements to grammar
parser. All identifiers, keyword and macros returned by new lexer
are converted to upper letters, do not have to be freed by hb_xfree()
and is guarantied that will be always accessible. So from grammar file
we can remove all hb_compIdentifierNew( hb_strupr($1), TRUE ) what
should give noticeable speed improvement but will break the FLEX code.
Ryszard and other you will have to decide if we will support FLEX in
the future. We can also clean the code and remove most of other
redundant hb_strupr() and hb_strdup() used in many places. BTW only
one terminal symbol can be returned with lower letters: DOIDENT
and I make it intentionally so it's possible to use:
DO prog1 WITH "sth"
on case sensitive file systems so this symbol should be cloned in
upper cases as function symbol but used without modification as
file name. It's current behavior but I'm not sure you will want
to keep it. Maybe compiler switch to always convert file names
created from
DO <id> [WITH <params,...>]
to lower cases will be better. Please think about it.

We still have some public functions which are not used by core code
and not declared in header files, like:
hb_memvarValueBaseAddress(), hb_memvarGetVarHandle(),
hb_memvarGetValueByHandle(), hb_clsCreate(), hb_clsAdd(),
hb_clsAssociate(), hb_hashTableDel(), hb_hashTableSize(),
I haven't touched them yet though we will have to keep in mind that
we should make sth with them.

+added support for DATE type constants in the following format:
0dYYYYMMDD
for example (see tests/ddate.prg for more):
IF( dDate > 0d20051112 )
+added support for SWITCH command (see tests/switch.prg)
SWITCH <expr>
CASE <integer_expression>
...
[EXIT]
CASE <string_expression>
...
[EXIT]
[OTHERWISE]
...
END
Notice:
- Integer and string expressions can be mixed in a single
SWITCH command with no runtime errors;
- CASE expression have to be resolved at compile time and
the result has to be either an integer or string constant
- if there is no EXIT statement then next CASE is executed
(or OTHERWISE for the last CASE)
For example:
CASE 1+32+2*4
CASE CHR(64)
CASE ASC('A')
CASE "A"+CHR(13)
Notice:
The above changes apply only to FLEX version!
