* source/rtl/isprint.c
! Fixed ISPRINTER() on Win32 after last changes.
Thanks Guillermo, pls test now.
* source/rdd/dbcmd.c
! Marked as HB_EXTENSION: FIELDLEN(), FIELDDEC(), FIELDTYPE()
* include/hbextern.ch
* source/rdd/dbcmd.c
! Marked as HB_EXTENSION: DBDROP(), DBEXISTS(), RDDINFO()
(they were properly marked in hbextern.ch but not in source)
* include/hbextern.ch
* source/rtl/disksphb.c
* source/rtl/fssize.c
* source/rtl/fstemp.c
* source/rtl/inkey.c
* source/rtl/oemansi.c
* source/rtl/philes.c
* source/rtl/setcolor.c
* source/rtl/setfunc.prg
* source/rtl/setkey.c
* source/rtl/shadow.c
* source/rtl/trace.c
* source/rtl/valtostr.c
* source/vm/dynsym.c
+ Removed HB_EXTENSION from all the .prg level functions
prefixed with HB_.
(there was a mixed situation here, but there's no need
to mark any HB_ functions as extensions, as it's obvious
by their name. So as a rule, no HB_ prefixed function
should ever be marked as HB_EXTENSION anymore.)
! Fixed some inconsistencies in HB_EXTENSION between
hbextern.ch and actual sources.
* source/rtl/tgetlist.prg
* One HB_EXTENSION changed to !HB_C52_STRICT because it
was guarding a bugfix rather than a real extension.
* source/rtl/gui.prg
* _GetNumCol() is now always strictly compatible.
NOTE added about sloppy C5.3 behaviour.
* source/rtl/inkey.c
* contrib/xhb/xhb.ch
* contrib/xhb/xhbfunc.c
! __KEYBOARD() xhb hidden parameter extension moved to
xhb lib. For similar functionality inside Harbour
pls use HB_KEYPUT(). __KEYBOARD is now 100% C5.x
compatible.
* source/rtl/setfunc.prg
* __SetFunction() extension now uses HB_KEYPUT() instead
of __KEYBOARD() extended parameters.
* source/compiler/hbfunchk.c
* source/rtl/at.c
! AT() extra parameters handled when HB_EXTENSION is on
(was !HB_C52_STRICT). (The first extra parameter is
XPP and Flagship compatible. The three parameter version
of this function is called AT3() in CAVO.)
! TRIM()/RTRIM() extra parameters handled on compiler level
when HB_EXTENSION is on (default).
! FILE() parameter check turned off in compiler.
(to be C5.x compatible)
* source/rtl/alert.prg
! ALERT() Harbour extended parameter (1st parameter type)
is now guarded with HB_EXTENSION instead of HB_C52_STRICT.
* source/rtl/gete.c
! GETE[NV]() Harbour extended parameter guarded with HB_EXTENSION.
* source/vm/proc.c
! PROCFILE() Harbour extended parameter guarded with HB_EXTENSION.
* source/rtl/mlcfunc.c
! Harbour extended parameters for MEMOLINE()/MLCOUNT()/
MLPOS()/MLCTOPOS()/MPOSTOLC() are now guarded with HB_EXTENSION
(instead of HB_C52_STRICT). It seems to be possible to
specify custom EOLs for all these functions. (Maybe simple
automatic Unix/Win EOL style handling would be better here)
* source/vm/memvars.c
! Guarded Harbour extension in __MVRESTORE() with HB_EXTENSION.
; After this cleanup:
- HB_EXTENSION is marking extra features living inside existing C5.x
functions or classes, or Harbour extension functions
not complying with the HB_ prefix rule (we have six
such functions in RDD). If there are more extended
parameters in Harbour pls mark them with HB_EXTENSION
too.
- HB_C52_STRICT is guarding bugfixes compared to C5.x.
- No HB_ functions are guarded with HB_EXTENSION anymore.
- We'd pbly need to review each HB_EXTENSIONs to check whether they
are safe or not.
- A list of HB_EXTENSIONs:
- MLCOUNT()
MEMOLINE()
MLPOS()
MLCPOS()
MPOSTOLC() - 5th and up can specify custom EOLs.
- ALERT() - 1st parameter type can be any type in Harbour, char only in C5.x
- SET FUNCTION TO
__SETFUNCTION - 2nd parameter can be numeric or array of numeric in Harbour.
- SETKEY() - 3rd codeblock parameter ("isactive" block)
- SAVESCREEN() - 5th parameter: lNoCheck (?)
RESTSCREEN() - 6th parameter: lNoCheck (?)
- AT() - 3rd and 4th parameters to set search range. 3rd parameter is
also supported by XPP and FS. Results in compiler error in C5.x.
(CAVO uses AT2() and AT3() for extended versions.)
- TRIM()
RTRIM() - 2nd parameter is an extension regarding space trimming mode.
Results in compiler error in C5.x.
- ALLTRIM() - 2nd parameter is an extension regarding space trimming mode.
- GETE()
GETENV() - 2nd parameter specifies a default value. Can be found in HB_GETENV().
- PROCFILE() - 1st parameter is a Harbour extension. Undocumented function in C5.x.
The extension looks similar to the one found in Flagship.
- __MVRESTORE() - 3rd/4th parameters are Harbour extensions to set variable name
mask. Redirected from the internal 5.x function named __MRESTORE().
- DB*() - cRDD, nConnection, cCodePage extra parameters in many DB*() functions.
TOFIX: None of them is marked as HB_EXTENSION.
- SET()s - These are not marked as HB_EXTENSION.
- ? - Is there anything else?
