% optimized directory array creation and fixed one TOFIX note
I left few warnings intentionally to mark places which should be
updated in the future (f.e. HB_SYMBOLSCOPE translations).
Victor, if you can please make build test with MSVC builds and
send the list of warnings which still exist to harbour-devel.
* harbour/include/hbapi.h
* harbour/source/vm/itemapi.c
* harbour/source/vm/garbage.c
+ added extended item references - it's universal reference which
can be used by HVM for many different things without introducing
new item types
* harbour/include/hbexprb.c
* respect -ks compiler also with <op>=, --, ++ operators
* harbour/include/hbvm.h
* harbour/source/vm/hvm.c
* harbour/source/vm/classes.c
+ added extended references for SETGET methods used as object
item references
* use extended references to respect overloaded [] operator in
object item references
+ added support for passing indexes to string item characters
( @cValue[n] ) by reference using extended references - extension
enabled by -ks compiler switch and //flags:s RT switch.
+ added hb_vmPushItemRef()
* harbour/source/rdd/dbf1.c
* harbour/source/rdd/usrrdd/usrrdd.c
* use hb_vmPushItemRef()
* harbour/contrib/xhb/xhbcomp.prg
* harbour/contrib/xhb/xhbmsgs.c
* overload +, -, *, %, ^, ++, -- in string and numeric scalar
classes to emulated xHarbour behavior when 1 byte string is
used as numeric value.
Note: <nun> + <char1> in XHB lib gives numeric value when in
xHarbour character. But because <nun> <anyOtherOper> <char1>
in xHarbour gives numeric value then I guess that it's
xHarbour bug and I should not replicate it, f.e.:
proc main()
? 1+"A", 131-"A", 33 * 2, 132 / chr(2), 133 % "C"
return
* overload +, - in hash scalar class to emulated xHarbour behavior
for <hash> + <hash> and <hash> - <hash>
Seems that now we can remove HB_COMPAT_XHB flag from HVM and keep
Harbour compatibility only with -ks compile time switch and XHB
library. Please make some tests with Harbour compiled without
HB_COMPAT_XHB and xHarbour code using REQUEST XHB_LIB. It's possible
that I missed sth but some basic test shows that our emulation is
better then original and addresses places where xHarbour does not
work at all or gives strange results, f.e.:
#ifndef __XHARBOUR__
request XHB_LIB
#endif
proc main()
local h:={"ABC"=>123.45}
? h:abc
h:abc+=1000 ; ? h:abc
h["ABC"]+=1000; ? h:abc
p(@h:abc) ; ? h:abc
p(@h["ABC"]) ; ? h:abc
return
proc p(x)
x+=1000
return
or:
#ifndef __XHARBOUR__

Now RELTEXT() works like FILTERTEXT() and the size of
expression is not limited. It's a modification I wanted
to make for a long time and I think that now is a good
moment to make it together with HB_FT_* modifications

+ added hash items, f.e.:
local h1 := {=>}, h2 := { "a"=>1.234, "b"=>2.345 }
? h2[ "a" ], h2[ "b ]
+ added support for DYNAMIC function declaration - it allow to define
functions which are lately bound at runtime, f.e.:
/*** t01.prg ***/
dynamic func1
proc main()
local h:=__hrbload("t02.hrb")
? func1()
return
/*** t02.prg ***/
func func1
return "Hello!!!"
% use new FUNCALL structure to hold EXTERNAL and DYNAMIC functions,
it reduce memory usage, FUNCALL is much smaller then FUNCTION
% use symbol scope bits when possible instead of making some linear scan
+ added new enumarator message: __ENUMKEY - it allow to access
key value when hash item is base enumerator value, f.e.:
proc main()
local v, h:={"a"=>1.000,"b"=>2.000,"c"=>3.000}
heval( h, { |k,v,i| qout( k, v, i ) } ); ?
for each v in h
? v, "=>", v:__enumKey(), v:__enumValue(), v:__enumIndex(), ;
valtype(v:__enumBase())
v += 0.123
next
? ;heval( h, { |k,v,i| qout( k, v, i ) } )
return
+ added C level hb_hash*() functions
+ added support for full HASH item cloning and updated array cloning
to also clone nested hashes - please note that xHarbour does not do
that, in xHarbour ACLONE() clones _ONLY_ nested arrays and HCLONE()
_DOES_NOT_ clone _ANY_ nested items.
* harbour/include/hbextern.ch
+ added hash functions HB_H*()
* changed INET*() functions to HB_INET*()
+ added hash functions H*() and socket functions INET*() when
HB_COMPAT_XHB is set
* harbour/include/hbtypes.h
+ added missing HB_EXTERN_BEGIN / HB_EXTERN_END
* harbour/include/hbpp.h
* harbour/source/pp/ppcore.c
! added protection against automatic word concatenation in some cases
! fixed preprocessing expressions when match marker matches ';' token
* harbour/source/rtl/Makefile
+ harbour/source/rtl/itemseri.c
+ added functions for item serialization: HB_SERIALIZE() and
HB_DESERIALIZE() - these function are not binary compatible
with xHarbour functions with the same names but make very
similar job with the exception to serialization of codeblock
and object variables - Harbour does not allow to serialize
codeblocks and serialize objects as arrays.
In most cases these functions can replace the xHarbour ones
+ added HB_DESERIALBEGIN() and HB_DESERIALIZE() functions covered
by HB_COMPAT_XHB macro - this functions are only for compatibility
with existing xHarbour code, In Harbour HB_DESERIALBEGIN() is
dummy function which returns first parameter and HB_DESERIALNEXT()
is a simple wrapper to HB_DESERIALIZE() so it's not necessary to
use them.
* harbour/source/rtl/hbinet.c
* changed INET*() functions to HB_INET*() and enable them for default
build
+ added INET*() functions wrappers covered by HB_COMPAT_XHB macro
* harbour/source/rtl/hbrandom.c
+ added HB_RANDOMINT() - xHarbour compatible
* harbour/source/rtl/len.c
+ added support for HASHes
* harbour/source/rtl/valtype.c
+ added support for HASHes
+ added set of HB_IS*() functions - they are a little bit faster then
calling VALTYPE( v ) == <cVal>
- removed HB_ISBYREF() - this function cannot longer work, it was using
a Clipper incompatible anomalies in passing variables by reference I
fixed so it has to stop to work. If it will be realy necessary to
implement HB_ISBYREF() function then please inform me - it will have
to be done at compiler level or with some much deeper HVM stack
checking.
* harbour/source/vm/extend.c
! fixed hb_extIsArray() and hb_extIsObject() to work well with
parameters passed by reference.
Please note that now hb_extIsArray() return TRUE only for pure arrays
not object values.

+ added TIP library - code borrowed from xHarbour
Please test - a lot of above code is not well tested, also some peaces
were written over year ago for different things (f.e. serialization for
NETRDD) and now I collected them and committed.
The TIP library was not tested at all. It can be compiled but I cannot
say if it works - I hope that people familiar with it can make necessary
test and fixes.
It's also not the final version of low level HASH item code. I'm working
on more efficient structure which uses binary tries but I cannot say when
I'll finish it (maybe in this weekend or maybe in next year) so I committed
working version now even if I'm not happy with overall performance (BTW
not worser then in xHarbour)
* harbour/include/hbapi.h
* harbour/include/hbapiitm.h
* harbour/source/vm/garbage.c
* harbour/source/vm/extend.c
* harbour/source/vm/itemapi.c
+ 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
* harbour/source/common/hbhash.c
* harbour/source/compiler/hbident.c
* formatting and minor modifications
* harbour/source/pp/pplib.c
* harbour/source/pp/pplib2.c
* use hb_parptrGC() to be sure that given pointer item points
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
* harbour/source/rdd/dbfntx/dbfntx1.c
* enabled code to seek in index using regular expressions
(DBOI_SKIPREGEX[BACK])
* harbour/source/compiler/hbusage.c
* update the year in hb_compPrintLogo() from 2006 to 2007
* harbour/source/vm/garbage.c
! fixed potentially very serious bug - when I added array items
references I forgot to update GC. Fortunately it was caught
by code to detect bugs in object destructors so only RT error
was reported instead of internal HVM memory corruption
* harbour/tests/hbinline.prg
* updated comments
+ harbour/doc/destruct.txt
+ added description for object destructors in Harbour
* harbour/include/error.ch
+ added new error code EG_DESTRUCTOR

* harbour/source/lang/msgpliso.c
* harbour/source/lang/msgplmaz.c
* harbour/source/lang/msgplwin.c

have to be updated
* harbour/include/hbapi.h
+ added hb_gcRefCheck() and cover some hb_gc* functions by
_HB_API_INTERNAL_ macro
* harbour/source/vm/itemapi.c

* harbour/source/vm/garbage.c
+ added support for object destructors
+ added logic to detect buggu .prg code which uses destructors
see doc/destruct.txt for more info.
It's also possible that this code will exploit some bugs
in other code which uses GC allocated memory blocks.
* harbour/source/vm/garbage.c
* minor cleanup
* harbour/source/rtl/cdpapi.c
* harbour/include/hbextern.ch
+ added HB_CDPLIST() - it returns array with all registered CODEPAGEs
* harbour/source/rtl/set.c
! fixed typo in _SET_DEFEXTENSIONS
* harbour/tests/testrpt.prg
! fixed syntax

* harbour/source/vm/extend.c
* harbour/source/vm/fm.c
* harbour/source/vm/hvm.c
* replaced direct stack access by stack functions/macros
* harbour/source/vm/debug.c
* removed hb_stackLenGlobal() and replace it by hb_stackTopOffset()
Warning!!! hb_stackTopOffset() returnes results smaller by 1.
The TOP stack item is undefined and should not be accessed by
debuger.
* changed HB_DBG_VMSTKGLIST() to operate on functions/macros.
It's possible that the above will badly interact with core debugger
code so I stop farther modifications leaving them for someone who
knows debugger core code.
* include/hbapi.h
* source/vm/garbage.c
* changed hb_gcUnregistedSweep to static function
* fixed handling of sweeper functions
* there is no need to call hb_UnregisterSweep - this
is done automatically inside hb_gcFree and during
garbage collecting
* harbour/source/rtl/gtgui/Makefile
* harbour/source/rtl/gtgui/gtgui.c
+ harbour/source/rtl/gtgui/gtdef.c
+ added GT version info
* modified the hack which overwrite the default GT name
Now original GTGUI is always present and only separate
file add linker bindings. It will be cleaner solution which
will allow to use REQUEST HB_GT_GUI in valid programs and
libraries.
* harbour/source/rtl/gtwin/gtwin.c
* indenting
* harbour/source/vm/garbage.c
* minor modification: use HB_GC_PTR() to take HB_GRABAGE pointer

* harbour/include/hbapi.h
* harbour/source/vm/garbage.c
* added some testing macros
* harbour/include/hbmath.h

+ added collect member to HB_IT_POINTER structure for POINTER items
inspected by GC
* changed the order of HB_CODEBLOCK members to safe few bytes on
alignment
* removed counters from HB_CODEBLOCK and HB_BASEARRAY structure
+ added hb_xRefInc(), hb_xRefDec(), hb_xRefFree(), hb_xRefCount(),
hb_xRefResize() functions. They are internal Harbour VM functions
and covered by internal API macro. Should not be used by 3-rd
party code because we may change them in the future or even remove.
+ added hb_gcRefInc(), hb_gcRefDec(), hb_gcRefFree(), hb_gcRefCount()
functions. These are also internal function which corresponds to the
above hb_x*() ones.
- removed hb_arrayRelease() function. This function is not longer
necessary and it should never be public function - it was implemented
in very dangerous way.
- removed hb_codeblockDelete() function.
- removed hb_memvarValueDecGarbageRef()
+ added USHORT usLen parameter to hb_codeblockMacroNew() - when sets
to non 0 value it informs that PCODE should be copied to dynamically
allocated buffer.
* moved all classes/object functions to separate file: hbapicls.h
+ added hb_retptrGC()
+ added internal function hb_memvarGetItem()
* harbour/include/hbapiitm.h
- removed hb_itemForwardValue() and added macro which translates
hb_itemForwardValue() to hb_itemMove()

* harbour/include/hbinit.h
+ added hb_vmProcessSymbolsExt(), hb_vmRegisterSymbols(),
hb_vmFreeSymbols(), hb_vmBeginSymbolGroup(),
hb_vmInitSymbolGroup(), hb_vmExitSymbolGroup()
* changed hb_vmProcessSymbols() to return address of register symbol
table. For normal code it's the same address as given in parameter
so it does not break backward binary compatibility.
* changed symbol init macros to work correctly with modified address
of symbol table
* harbour/include/hbsetup.h
* added support for HB_USE_PROFILER macro. Now profiler code is
is disable in HVM by default
* commented out HB_ASORT_OPT_ITEMCOPY - it's not longer used - see note.
* harbour/include/hbstack.h
* added missing parenthesis in hb_stackItem() macro
* harbour/include/hbtypes.h

without any machine code
* use stack function/macros instead of direct accessing HB_STACK members
* separated profiler code
* some code cleaning
* harbour/source/vm/codebloc.c

and covered by internal API macro. Should not be used by 3-rd
party code because we may change them in the future or even remove.
* harbour/source/vm/garbage.c
+ added hb_gcRefInc(), hb_gcRefDec(), hb_gcRefFree(), hb_gcRefCount()
functions. These are also internal function which corresponds to the
above hb_x*() ones.

table. For normal code it's the same address as given in parameter
so it does not break backward binary compatibility.
+ use new code for operator overloading
* changed FOR EACH to dynamically check iteration scope in
hb_vmEnumNext()/hb_vmEnumPrev() and remove max number of iteration
stored on HVM stack
* temporary use hb_itemUnRefOnce() instead of hb_itemUnRefRefer() as
workaround for possible GPF. I'd like Ryszard will chose the final
version

+ harbour/include/hbgtinfo.ch
+ added GTI_* defintions for hb_gtInfo() function.
This function works in similar way to dbInfo() in RDD.
The GTI_* definitions are taken from xHarbour "as is" and
they should be cleaned - not all functionality are supported
in Harbour and some others should be implemented in differ
way then in xHarbour.
+ harbour/include/hbgtcore.h
* harbour/include/hbapigt.h
* new GTAPI
hbgtcore.h file should not be included by user code
it's only for internal use in GT drivers
* HB_inkey_enum changed to int - this is bit field not enumerated type.
Many of C/C++ compilers forbid bit operations on enum types and
forcing it by casting which finally exceeds the enum range is defined
as bug because it may badly interacts with some compiler optimizations

* harbour/include/hbstack.h
* harbour/include/hbvm.h
* harbour/include/hbvmopt.h
* harbour/include/hbvmpub.h
* separated internal and external API. Now the definitions for
internal HVM structures and functions are excluded by default
they could be enabled if user include hbvmopt.h before other
header files. Such operation should be done _ONLY_ by core
code - if 3-rd party developers make sth like that then it's
for their own risk and such code may stop to work with next
Harbour versions. Without hbvmopt.h the internal structures
like HB_ITEM, HB_DYNS, ... are mapped to 'void' so there is
no way to access their members so we can modify them in the
future without afford for 3-rd party code.
There is one small exception 'type' should be the first member
for HB_ITEM structure because I used a small ugly hack in
HB_IS_*() macros with castin PHB_ITEM to HB_TYPE* - it works
without speed overhead but if you think that it will be
better/cleaner to not use such tricks then it's enough to
change HB_ITEM_TYPE() definitions in hbvmpub.h - see note.
* cleared the usage of HB_EXPORT - to avoid problems with some C/C++
compilers we agreed that the only one common way of using HB_EXPORT
is adding it ad begining of declaration - please keep this convention
in the future.
+ added new functions:
hb_extIsObject(), hb_codeblockId(), hb_idleSleep(),
hb_fsGetOsHandle(),
hb_dynsymFindSymbol(), hb_dynsymGetSymbol(),
hb_dynsymSymbol(), hb_dynsymName(),
hb_dynsymMemvarHandle(), hb_dynsymAreaHandle(), hb_dynsymSetAreaHandle()
* changed hb_arrayClone() declaration to:
PHB_ITEM hb_arrayClone( PHB_ITEM pArray )
* changed hb_arrayFromParams() declaration to:
PHB_ITEM hb_arrayFromParams( int iLevel )
The previous version needed a pointer to stack relocatable area
so any stack resizing could cause GPF.
* harbour/include/inkey.ch

% rewritten jump optimization
! fixed some minor problems
* do not optimize jumps and local variable access by shorter
PCODE version and HB_P_NOOP when jump optimization is
disabled, this is a note I left in source code in few places:
/*
* optimizing jumps here by shorting them and setting HB_P_NOOPs
* only slow down the compilation process for three reasons:
* 1. When it's dummy jump to next instruction we need two passes
* in hb_compOptimizeJumps() to fully remove it
* 2. hb_compOptimizeJumps() also make jump shortcutting in each pass
* 3. When Jump Optimization is disabled (-kJ) then it cause slowness
* at runtime because we will have more HVM loops: first for the
* shorter jump and next for the HB_P_NOOP PCODE(s)
* [druzuz]
*/
+ added support for multi passes in jump/dead code elimination
(hb_compOptimizeJumps())
By default is set upto three passes.
Now hb_compOptimizeJumps() keeps all compiler internal data clean
on exist and can be called any times and does not change other
compiler's functions behaviors
+ added dummy jumps elimination
+ added optimization for:
IF .T.
IF .F.
WHILE .T.
WHILE .F.
etc.
* restored empty BEGIN/RECOVER sequence block elimination
if Jump Optimization is enabled then it marks the block
with HB_P_NOOPS else it cut the generated PCODE
+ added dead code eliminator (new functions hb_compCodeTraceMarkDead()/
hb_compPCodeTrace() - it works only when Jump Optimization is
not disabled)
As a result of the above we have smaller and faster PCODE.
I do not think that we will have meta code support in the reasonable
time and because I need some valid compiler data/structures like
updated table of all jumps for real C code (not PCODE in .c files)
generation then I decide to make some modifications and the above
is in practice a side effect of this work.

binaries created by make_rpm.sh and make_tgz.sh
Ryszard I've removed some of your extensions which are no longer
necessary and some other (keyboard sequence redefinition) should
be done in a little bit differ way. I would like to talk about it
when you test current code.
Added support for extended mouse keys (middle button and wheel).
* harbour/source/rtl/gtdos/Makefile
* harbour/source/rtl/gtdos/gtdos.c
- harbour/source/rtl/gtdos/mousedos.c

Fixed some small problems, finished mouse code which for DJGPP
is fully Clipper compatible with real mouse SAVE/RESTORE code.
For other compilers it should be updated depending on memory
model and used DPMI driver (if any).
* harbour/source/rtl/gtos2/Makefile
* harbour/source/rtl/gtos2/gtos2.c

I was not able to make any test. I'm interesting in information
if it works and the speed difference - f.e. results from
tests/vidtest.prg run with previous and current version.

* rewritten for new GT API basing on current xHarbour code
added support for slang 1.4x patched for UNICODE (Debian
patches used by most of current Linux distributions) and
slang 2.x - It's unicode ready, tries to detect terminal mode
(utf-8/iso) at startup and switch the internal logic to
iso/unicode mode. When compiled with slang 1.4x or 2.x
and terminal is in UTF-8 it can display all characters like
in DOS if only used font have them or good fall-back table is
loaded (f.e. the one created by QRCZAK)
Added support for extended mouse keys (middle button and wheel).
* harbour/source/rtl/gtstd/Makefile
* harbour/source/rtl/gtstd/gtstd.c
- harbour/source/rtl/gtstd/mousestd.c

screen contents from internal GT core buffers. I run with this
GT some of my programs and they work quite well ;-) of course
without colors.
* harbour/source/rtl/gtwin/Makefile

+ harbour/source/rtl/gtxwc/gtxwc.c
+ harbour/source/rtl/gtxwc/gtxwc.h
* new XWindow Console GT driver based on my and Giancarlo Niccolai
code form xHarbour - this GT can work in XWindow environment only
and create its own window for console output. It delays the
initialization to the moment when user try to display anything on
the screen so even without X Window system programs which uses this
GT can work as long as use only outstd/outerr output.

which save/restore HVM state (the top stack value which can be
processed and return item and maybe sth else in the future) making
HVM ready for reentrant.
* harbour/source/vm/itemapi.c

what broke GNU make compilation for some compilers
This libraries should be included automatically when RDD lib
is included by *.cf files
Summary:
The whole patch (cvs diff -uN) is ~1.5MB length and I cannot describe
everything in details - sorry but it was too much modifications in
one commit so now just some of general notes.
The header files included as is does not have any information about
internal HVM structures and some functions. In practice only HB_SYMB
is public and it has to be public for .c files generated from .prg
so I force the fixed size of this structure (alignment independent)
by redefining some members to union with void * - it's a little bit
ugly trick but it effectively eliminates the problem of linking
binaries compiled with differ alignment C compiler switches.
The structures like HB_ITEM, HB_CODEBLOCK, HB_STACK, HB_DYNS are not
longer defined and pointers to the defined as void * - like in Clipper
the ITEM structure. It caused that I had to add some new functions
to make some operation still possible to implement. If I missed sth
and any of you will have a problem with your code then please inform
me about it and after a small discussion on Harbour developers list
we can decide if other functions should be added.
The internal API is still accessible. It's enough to include "hbvmopt.h"
file before other header files to enable it. Now only files in
source/vm directory include it.
The 3-rd party code which does not include hbvmopt.h (or tries to
set some internals macros) should be safe for future HVM modifications
and will work also with new binaries so 3-rd party library developers
should remember about it. If they won't then it's only their and
their clients problem not Harbour developers.
With this modifications I also create new GT model which is similar
to the one used by RDD with multi inheritance. It can be quite easy
extended to simultaneously load more then one GT subsystem (sth like
work areas in RDD) but I left it for the future when someone may
need it. hbapigt.h file now contains only information about public
functions and does not have any code which depends on current
internal implementation - it should be backword compatible as long
as somone did not try to use internal GT functions.
The internal GT system use hbgtcore.h file which should not be
included by 3-rd party code as long as someone will not make new
GT driver. The internal GT code is new so I expect that it will
be changed yet in the nearest future (I'm waiting for other developers
feedback) and in such case any 3-rd party GTs will have to be updated.
How it works:
The base GT driver (GTNUL) is fully functional GT driver which
makes all operations on memory buffer. After each screen write
Flush() method is called which check for dispcount() and if
it's 0 then call Refresh() method to update modified area by
Redraw() method. This method is dummy in GTNUL and external
output with this GT can be reached by outstd()/outerr() which
are now redirected to GT methods. A simple GT driver may overload
only Refresh() method to give full screen output.
Application can use only this GT driver and it seems to be very
good choice for GUI and background daemon/service programs.
This GT is loaded at startup then all other GTs can be loaded
later and inherit from the previously loaded GT drivers.
The new GT driver can overload as much method as wants/needs.
Now all GT operations are implemented as GT method so GT driver
can easy change their default behavior, f.e. it may fully overload
color parsing methods and use differ or extended to Clipper color
definitions.
I rewrote all existing GTs to work with new GT model.
OS2 users - please test GTOS2 which I was not able to test and
see the note in Redraw() method. If possible please make some
speed tests.
In fact now there is much more internal operations then it was
before but because they are done on memory only then current
code is much faster in this GT drivers which so far makes all
operations on real video area. I made some tests with GTNUL
and tests/vidtest.prg and the total overhead is minimal. Now
dipbegin()/dispend() in practice does not cost anything so it
gives additional speed improvement in application which extensively
use it.
More then one GT driver can be linked with final binaries and
chose on application startup by //GT<NAME> switch and/or environment
variable HB_GT=<name>
In the RTL is new GT function GTSYS() which works in similar way
to RDDSYS() in RDD subsystem and for linking default GT driver
for given platform. When RTL is compiled the default GT driver
is set to HB_GT_DEFAULT envvar and if not exist to HB_GT_LIB
envvar and if it also does not exist to hard coded platfom GTs
(see source/rtl/gtsys.c and source/rtl/Makefile for rules)
Adding to source code:
ANNOUNCE GTSYS
disable linking the default GT driver and:
REQUEST HB_GT_<name>
for linking given (<name>) GT driver, f.e.: REQUEST HB_GT_WIN
If you are working in SH environment (Linux and other *nixes users,
DJGPP bash, MinGW shell then it's possible to use -gt<name> switch
in hblnk / hbmk scripts to force linking GT drivers (it could be
repeated with different <name>) and the first one becomes the default
one. F.e.:
xhbmk -m -n -w -es2 -gtcrs -gtsln -gtstd -gtpca vidtest.prg
Usually the GT driver are loaded at HVM startup but it's possible
to load it later. I created new GT driver CTW which gives full
CT3 like Window system. The CT3 extended driver change the behavior
of some function in Clipper extended driver, f.e WRITECON() or
SETPOS() with parameters out of screen range. So I implemented it
CTW as RT GTs which is loaded when some of CTWIN function is used
(f.e. WOPEN()/WBOARD()) and inherits from any existing GT driver.
This is full CT3 WIN implementation with all detail behaviors I
found (with some CT3 bug fixes). It does not have any CT3 limitations
and can be used for any virtual screen/window size though I hardcoded
CT3 limitation for backword compatibility. If somone will want to
remove it then it will be enough to delete few lines from ctwin.c
file. I'm not CTWIN Clipper user so maybe I missed some side effects
in this driver and was not able to well test it so if you will find
any incompatibilities then please inform me.
THe default GT buffer uses 32bit character cell internally but
in savescreen/restscreen it uses VGA compatible two bytes character
cell. Some GT drivers may want to use differ character cell.
Now GTCRS and GTSLN use 32bit character cell by default. They
need additional information about character set (box/normal) to
properly display box characters. It is possible to force in this
GT drivers using Clipper compatible character cell by calling:
hb_gtInfo( GTI_COMPATBUFFER, <lCompat> ) -> <lPreviousSeting>
but in may cause that box drawing characters will be lost in
some countries after RESTSCREEN(). It will depend on used code
page.
HB_GTINFO() is new function which works in similar way to DBINFO()
in RDD. It allows to retrieve/change some of GT driver settings.
GTI_* actions are defined in hbgtinfo.ch - it has all GTI_*
definitions used in xHarbour. Now in Harbour only few of them
are implemented.
The new three .prg functions:
HB_SETKEYCP( <cTermCP> [,<cHostCP>] )
HB_SETDISPCP( <cTermCP> [,<cHostCP>] [,<lBoxChar>] )
HB_SETTERMCP( <cTermCP> [,<cHostCP>] [,<lBoxChar>] )
have been added. They set automatic input (HB_SETKEYCP)
and output (HB_SETDISPCP) (or both: HB_SETTERMCP) character
translation. They are also important for some GTs which
informing them about used internal code page for unicode
translation (GTXWC, GTSLN) and/or chosing proper character
set (standard/alternate) for letters and other (f.e. box
drawing characters) (GTCRS, GTSLN),
<cTermCP> is encoding used on external (terminal) side
<cHostCP> is encoding used internally, if not given then
current code page set HB_SETCODEPAGE() is used.
some of GTs which uses unicode output may
ignore <cTermCP>
<lBoxChar> is optional parameter which interacts with dispbox()
output disabling switching to alternate character
set in some GTs. It effectively causes that if internal
(host) code page contains some letters on the box char
positions then they will be shown also by box drawing
functions like dispbox() instead of CP437 characters.
In some cases it could be useful. By default lBoxChar
is not set and GTs which can switch between standard
and alternate character set (GTCRS, GTSLN) will try to
use alternate character set for box drawing functions.
Victor: I removed some of your functions. They can be very easy
implemented with hb_gt_GetChar()/hb_gt_PutChar() but I do not want to
make them part of documented external API because some GT drivers may
want to use absolutely differ color definitions and they will stop to
work so I do not want to make this functions documented external API.
Ryszard: Setting alternative debug keys does not longer work.
I like such possibilities but it should be implemented in differ
way to f.e. using HB_GTINFO interface to allow low level GT driver
extensions, f.e. in *nixes using CTRL+[A-Z] and SIGINT, SIGQUIT,
SIGTSTP signals for real asynchronous setting of debug/cancel flag
without keyboard polling from main HVM loop. I would like to discus
about such more general solution.
*** Please updated non GNU make files ***
* harbour/source/vm/garbage.c
- removed unnecessary memset()
* harbour/source/vm/hvm.c
% use startup initialized symbols: hb_symEnumIndex, hb_symEnumBase,
hb_symEnumValue instead of strcmp( pSym->szName, ... ) in hb_vmSend()
% remove unnecessary temporary item in hb_vmEnumStart() and use
hb_itemMove() instead of hb_itemCopy()+hb_itemClear()
% changed main VM loop to eliminate one comparision done on each
loop. Now HB_P_ENDBLOCK and HB_P_ENDPROC pcodes set HB_ENDPROC_REQUESTED
and the main loop can be exited only from one place. It gives some
small but noticeable speed improvement.
Ryszard please check this modification. AFAIK it should not cause
any bad side effect and IMHO the code is cleaner now.
* harbour/source/vm/itemapi.c
% removed two unnecessary hb_itemClear() before hb_itemRelease()
* harbour/config/bsd/global.cf
+ added suppot for HB_COMMERCE and HB_WITHOUT_GTSLN env vars
* harbour/source/compiler/Makefile
* formating
* harbour/include/hbdefs.h
* harbour/source/vm/fm.c
* harbour/source/vm/garbage.c
+ added macro HB_ALLOC_ALIGNMENT which forces allocated memory
alignment in FM and GC modules to given value - by default used
only when set HB_OS_SUNOS with 8 bytes alignment
