[fpc-devel] FmtBCD unit improvements / bugs
Hi, I would like to ask somebody to look at these bug reports: 1. http://bugs.freepascal.org/view.php?id=18388 This bug report contains implementation of missing BcdToStrF function. There is also discussion if FmtBCD unit is localized ... tests under Delphi (6,10) shows, that Delphi *uses* global variables DecimalSeparator (in StrToBCD, BCDToStr, BCDToStrF) and ThousandSeparator (in BCDToStrF). 2. http://bugs.freepascal.org/view.php?id=18807 If fix in bug report (1) will be applied, then I can continue by adding overloaded functions TryStrToBCD, StrToBCD, BCDToStr with next parameter const Format: TFormatSettings (in style of TryStrToFloat etc. and also in Delphi compatible way) and drop global variable DecimalPoint and replace its using by either DefaultFormatSettings (when used function without Format parameter) or supplied Format parameter. So it will be something like this: function TryStrToBCD ( const aValue : FmtBCDStringtype; // --- here is not specified Format, so use DefaultFormatSettings var BCD : tBCD ) : Boolean; begin Result:=TryStrToBCD(aValue, BCD, DefaultFormatSettings); end; function TryStrToBCD ( const aValue : FmtBCDStringtype; var BCD : tBCD; const Format: TFormatSettings ) : Boolean; // --- here is explicitly specified Format, so use it ... //here use Format.DecimalSeparator , Format.ThousandSeparator ... I would like if we make progress in this, because then we can continue with other task related to this. Please let me know if you agree with this direction and if yes, then please apply fix in (1) and then I will prepare fix for (2) Thanks -Laco. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

(-R means recursively dive into subdirectories and -Tall means for all targets) That should not be necessary, all makefiles in svn contain support for all targets. The error The Makefile doesn't support target can't-executed indicates that the Makefile tried to execute the compiler to figure out for what target it should install files, but could not execute it (hence the can't-executed target name). It's possible that fpcmake also needs to be in the path (I also remember that for some reason it's executed during make install), but it's not the cause of this particular error.

(supposedly some files were owned by root and could not be overwritten when making fpc as a user) OTOH, I think I need to do make install as root if I want to provide fpc in /usr/bin to all users. It's hard to tell without the error message. This is obvious but right now I don't get this problem any more. I suppose I could reproduce it by deleting the fpc* files from /usr/bin. I now think it's likely that fpcmake had been the file make install complained not to have.

So if you want to overwrite or create it: cd compiler make FPC=./ppc386 installsymlink Jonas___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

So I'd like to change the syntax for mode ObjFPC a bit (sadly this won't simplify the parser anymore because of the Delphi compatibility). Delphi syntax: TypeIdentifier = class|record helper(ParentHelper) for ExtendedType Proposed FPC syntax: TypeIdentifier = helper(ParentHelper) for class|record ExtendedType What do you think? Maybe also the class|record part can be left out, because this part is not saved in the objectdef and can be determined by the compiler automatically. I always think that if there is no need to create an incompatibility - better to not create it. But my ideas often does not get support of other FPC developers. I have tought about this topic a bit more. On the one hand I still want a cleaner syntax for this, but on the other hand I also understand that others want to have the ability to use objfpc code in Delphi with as less ifdefs as possible (or the other way round). So what about the following compromise: I will add my proposed syntax, but the Delphi compatible one can be activated with a mode switch (which will be enabled by default in mode Delphi). And if you really insist very hard to have mode ObjFPC compatible with mode Delphi, I can also live with the switch meaning enable non compatible syntax and being disabled by default. I plan to do something similar when RTTI attributes are implemented (either by me or someone else) as well, so the modeswitch will have its use there, too.
