+ harbour/tests/hsxtest.prg
+ added test code for HiPer-SEEK indexes
* harbour/source/rtl/filesys.c
+ added new functions: hb_fsExtName(), hb_fsReadAt(), hb_fsWriteAt(),
hb_fsTruncAt() to use with shared file handles.
Please test it in other *nixes. I used pread[64]()/pwrite[64]()
POSIX functions but I do not know if they are available by default
in other supported platforms like MacOSX, BSD, HPUX, SunOS.
If not they I will have to implement some workaround.
* harbour/common.mak
* harbour/source/rtl/Makefile
* harbour/include/hbapifs.h
+ harbour/source/rtl/filebuf.c
+ added set of new file functions (hb_file*()) which are designed to
use with shared file handles and locks (buffers in the future):
hb_fileExtOpen(), hb_fileCreateTemp(), hb_fileClose(), hb_fileLock(),
hb_fileReadAt(), hb_fileWriteAt(), hb_fileTruncAt(), hb_fileSize(),
hb_fileCommit(), hb_fileHandle()
These functions operate on PHB_FILE structure instead of HB_FHANDLE.
Now in POSIX systems they share file handle between aliased or
simultaneously open by other thread work areas. It resolves the
problem with releasing all process FCNTL locks by any close()
operation even on duplicated or open() separately handle.
Now DOS deny flags emulation works in single process even if
BSD locks are disabled (non Linux *nixes).
They also keep internal file lock list what allows to synchronize
threads and aliases with file locks in POSIX systems. In the future
it will be used also for internal locking to synchronize threads
without OS level locks - pseudo exclusive mode in cloned WA.
Finally these structures will be used also for file buffers
which will be shared between aliased WA and threads.

keeps dynamic symbol table locked during whole execution.
It's faster then hb_dynsymEval() but user function may not
access dynamic symbol tbale to not cause recursive locks
+ added protection against possible dynamic symbol table resizing
during hb_dynsymEval() by other threads.
* harbour/include/hbapi.h

HB_THREAD_INHERIT_MEMVARS
HB_THREAD_MEMVARS_COPY
* harbour/include/hbthread.h
* harbour/source/vm/hvm.c
* harbour/source/vm/thread.c
+ added support for inheriting visible memvars from current
thread when new thread is created. Memvars in child thread
can be shared with parrent or they can be copied. See HB_THREAD_*
attributes defined in hbthread.ch, f.e.:
hb_threadStart( HB_THREAD_INHERIT_PUBLIC, @thFunc() )
or:
hb_threadStart( HB_BITOR( HB_THREAD_INHERIT_MEMVARS + ;
HB_THREAD_MEMVARS_COPY ), ;
@thFunc() )
Please note that when child thread creates new PUBLIC variable
which didn't existed when thread was started then it's visible
only for this thread and optionally for its child threads but
not for parent thread.
Please also remember that write access to shared memvars have
to be protected by users.

create applications for WinCE on PockePC with ARM processors on
Linux or MS-Windows can download from SF cegcc-mingw32ce port.
User using RPM based Linux distribution for x86 CPUs can simply
download cegcc-mingw32ce-0.50-1.i586.rpm and install it.
The hb* scripts created by ./make_xcemgw.sh [tgz|gnu] are
automatically updated to work with CeGCC-MinGW32 so later you
can simply crate WinCE-ARM binaries using them as for native port.
I'm waiting for users feedback. Please remember that I'm not Windows
user and even this port was created without any Pocket machine.
With Marek Paliwoda help I only tested that final applications are
working using PocketPC emulator.

+ added SIx3 compatible triggers support
They should work like in SIx3 with some intentional excpetions:
1) if 4-th parameter exists (PREUSE/GET/PUT) then it's passed by
reference otherwise is not passed at all and PCOUNT() in trigger
functions returns 3
SIx3 do not pass 4-th parameter by reference and if it not
exist then passes 0
2) EVENT_POSTCLOSE is executed after SUPER_CLOSE()
SIx3 executes EVENT_POSTCLOSE just before SUPER_CLOSE()
3) EVENT_UPDATE is executed _ALWAYS_ when DBF is updated also
when WA does not have open indexes
SIx3 executes EVENT_UPDATE only when at least one index is
open without checking if it's updated or not
4) EVENT_POSTUSE is executed from OPEN() method in "DBF" RDD not
from index RDDs so before the indexes are open
SIx3 executes EVENT_POSTUSE after opening indexes
It's possible that I'll change this condition in the future

+ harbour/source/rtl/hbadler.c
+ harbour/source/rtl/hbcrc.c
+ harbour/source/rtl/hbmd5.c
+ added functions to calculate different checksums
HB_ADLER( <cValue> [, <nStart> ] ) -> <nCC>
HB_CRC32( <cValue> [, <nStart> ] ) -> <nCRC>
HB_CRC16( <cValue> [, <nStart> ] ) -> <nCRC>
HB_CRC ( <cValue> [, <nStart> ] [, <nPolynomial> ] ) -> <nCRC>
HB_CRCCT( <cValue> [, <nStart> ] [, <nPolynomial> ] ) -> <nCRC>
HB_MD5( <cString> ) -> <cMD5>
HB_MD5FILE( <cFileName> ) -> <cMD5>
HB_CRC() is general CRC function which can be used for any polynomial
given as second argument, f.e.: 0x104C11DB7 is CRC32 polynomial,
0x18005 -> CRC16, 0x11021 -> CRC16 X.26, 0x1393 -> CRC12, 0x101 -> LCR8
HB_CRCCT() makes exactly the same job but it uses broken algorithm.
Unfortunately it seems that this broken version is widely used by many
other projects, f.e. HB_CRCCT() gives exactly the same results as
COM_CRC() from CT3. Generated results are usually "good enough" but
if you do not need compatibility with some other tools which uses
broken CRC algorithm then I suggest to not use it.
HB_ADLER() is ADLER32 check sum - this function gives the same results
as HB_CHECKSUM in xHarbour.
HB_MD5*() functions are from Dmitry V. Korzhov code modified a
little bit by me for other then x86@32 machines files and buffers
longer then 2^32. I also fixed possible problems with wrong results
in some cases.

This Ron's code which illustrates it:

In practice it means that we do not need this PCODE at all and
we should replace it in compiler by HB_P_POPMEMVAR and reuse
it in the future for differ things.

+ added all CL5.3 BLOB*() functions support

It operates on memo files only (.dbv) without tables (.dbf)
To create .DBV file use:
dbCreate( cFile, {}, "DBFBLOB" )
* harbour/source/rdd/dbcmd.c
* do not report error when empty structure table is passed to DBCREATE()
CL5.3 allow to create even DBF files without any fields and because
I can imagine some valid code which use it as a feature then I also
allow it in DBF RDD.
Authors of RDDs which do not allow to create tables without fields
should add to their low level RDD code necessary RT error.

! fixed double value presented in verbose genc mode for HB_P_PUSHDOUBLE
! fixed number of cases presented in verbose genc mode for HB_P_SWITCH
* harbour/source/compiler/hbdead.c
+ added support for dead code elimination in functions which uses
SWITCH ...; CASE ...; ...; END syntax
* harbour/source/compiler/harbour.c
* harbour/source/compiler/hbfix.c
! fixed optimization for HB_P_PUSHLOCALNEAR and HB_P_POPLOCALNEAR.
It was a long existing bug not reported so far because 0, 1 and 2
PCODEs uses only one BYTE and bad PCODE tracing in hbfix.c didn't
caused bad side effects as long as number of locals in function
was smaller then 768. Now for functions HB_P_PUSHLOCAL and
HB_P_POPLOCAL is used and later changed to NEAR version in hbfix.c
if possible.
* harbour/source/compiler/hbfix.c
* join sequential jumps to optimize constructions like:
while ...
...
if ...
exit
endif
enddo
* harbour/source/compiler/hbdead.c
* remove HB_P_END PCODE also at the and of function if is repeated
just before, f.e. in code like (source/rtl/color53.prg):
Function RADGRDEFCO( cColor )
if isdefcolor()
Return applydefau( cColor, "W/N", "W/N", "W+/N")
Else
Return applydefau( cColor, 3, 1, 4)
endif
Return nil
Now such redundant constructions like above are fully stripped by
compiler anyhow if someone has time and think is important then can
clean also this .prg code.

* harbour/source/vm/hvm.c
+ added support for generating real C code not PCODE in .c files.
Now with -gc3 Harbour will generate .c files with real .c code
which is later compiled to real machine code.
I left PCODE only for code block definitions though it's also
possible to have even code block compiled to machine code but
we will have to add a flag to codeblock structure which will
be checked at runtime and proper method of execution in EVAL
will be chosen. If you think it's worth of afford then I can
add it too in some spare time.
The final binaries are noticable longer then the one which has
only PCODE but they are faster. The speed improvement depends
on type of operations. The pure Clipper code which does not
execute any external time consuming C functions compiled with
-gc3 is from 10% to 50% faster.
The side effect of generating pure machine code is also harder
recompilation but it does not mean that is impossible. If sth
can be executed by some machines (virtual or hardware) then it
can always be decompiled by definition.
This modification opens door for farther optimization, f.e. when
we will have fully working strong type support then we can add
using native .c types.
In fact this module is PCODE to .c translater not part of compiler
and can be used as separate module to translate generated PCODE,
f.e. .hrb files.
Maybe in the future we will change the compiler to generate meta
code not directly PCODE and it will be possible to make optimizations
on this meta code which will depend on selected output type:
VHM PCODE, C code, .NET code, etc. but at this moment adding support
for .c compilation directly into compiler will make the compiler code
too much complicated for me - IMHO it's better to invest time into
clear separation to FRONT_END->REAL_COMPILER->BACK_END
Please make test with your code. I rebuild whole Harbour code with
-gc3 set in HB_FLAGS in harbour/config/rules.cf and all seems to
work correctly. hbtest returns exactly the same results.
I also made tests with my programs and they work correctly but
I had to define actions for all PCODEs and it's possible that made
some typos in some of them which are very seldom used so your tests
will be very important.

problem with GPFs reported by users and some possible memory
leaks when preprocessing/compilation process is interrupted.
Ryszard I decided to always store copy of file name in open
files structure - it can be used by compiler, preprocessor,
PPLIB and HBPP and IMHO in all cases it should have valid
and always initialized in the same way members for easier
manipulation. In the future I'd like to clean the whole PP
usage. I will need to keep all compiler and PP static variables
in one structure pointed by pointer in thread local data or
passed to called functions for MT support.
* harbour/source/rtl/cdpapi.c
* set 0 at the end of destination string in hb_cdpStrnToUTF8()
* harbour/source/rtl/dateshb.c
! fixed possible GPF in CTOD when badly formated date is given
* harbour/source/rtl/gtxwc/gtxwc.c
* harbour/source/rtl/gtxwc/gtxwc.h
* changed the selection code - now both PRIMARY and CLIPBOARD
selections are set by Harbour. It should work with any programs
which uses any of them but I'd like to remove one of this selections
or give user a way to chose the preferred one. I can also add support
for automatic setting/clearing/pasting PRIMARY selection by GTXWC
with mouse and shift key. I'm waiting for opinions.
+ added basic support for GFX operations

+ harbour/source/rtl/gtalleg/ssf.c
+ harbour/source/rtl/gtalleg/ssf.h
+ added new GT by Mauricio Abre based on Allegro cross platform
graphic libraries.
Code borrowed from xHarbour and modified by my for new Harbour
GT API.
* harbour/include/Makefile
* added missing header files
* harbour/source/compiler/harbour.c
* added support for @filelst[.clp] - partially borrowed from xHarbour
It's not exactly the same as in Clipper because Clipper creates
one final file when [x]Harbour series of files.
To make it like in Clipper we will have to add support from more
then one symbol table in the final file. It will be also useful
for proper implementation of:
DO <file>
Now in [x]Harbour it works like #include <file>.prg when in Clipper
also new symbol table is created for included files. The difference
can be easy sync when current file has static functions with exactly
the same names as the one included by DO - compilation fails.
* add HB_P_ENDBLOCK to PCODE with codeblock body before run any
optimization - it fixes pcode tracing in jump optimization and
also allow to make some validation of generated PCODE
* harbour/source/rdd/dbstrux.prg
* harbour/source/rdd/dbtotal.prg
* removed not longer necessary temporary alias creation. Harbour
support empty aliases ("") like Clipper.

* synced with xHarbour
* harbour/include/Makefile
* added new header files
+ 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/hbapi.h

* 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
* rewritten for new GT API
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
- harbour/source/rtl/gtos2/mouseos2.c

Fixed some problems and finished the mouse code.
Please test it - I made all modifications without OS2 and
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.
* harbour/source/rtl/gtpca/Makefile
* harbour/source/rtl/gtpca/gtpca.c
- harbour/source/rtl/gtpca/kbdos2.gcc

I'm interesting in keyboard sequences used by PC-ANSI drivers
in DOS so it will be possible to implement also support for
extended keys input.

* 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/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.

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.
