[fpc-pascal] UnicodeString and surrogate pairs
Hi, Does FPC's RTL (or FCL) include a function to check for UTF-16 surrogate pairs? I'd be very surprised if there isn't, but I have yet to find it in the documentation or source code I searched. I need to process one "character" (loosely based on what you see on the screen) at a time while calculating text width up to a maximum width. I need to make sure I handle all Unicode text correctly, thus NOT just the BMP of the Unicode standard, but all supplementary planes too. My alternative is to convert the text from UTF-16 to UTF-8 and then process it, but in this instance I'm hoping to stay with UTF-16 [never thought I would ever say that out loudly! ;-)] Regards, Graeme -- fpGUI Toolkit - a cross-platform GUI toolkit using Free Pascal http://fpgui.sourceforge.net/ My public PGP key: http://tinyurl.com/graeme-pgp ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
[fpc-pascal] Iterator for Unicode encoded strings
Hi, This question really applies for all Unicode encodings (UTF-8, UTF-16 and UTF-32). In the modern world you simply can't use indexed access into Object Pascal strings to retrieve a "character" (loosely what you see on the screen - ignoring combining diacritics). In my own projects I have custom written Iterators for various data types like StringList, ObjectLists etc, and that includes strings. I know FPC RTL supports the Iterator concept (not as advanced as what I have implemented), but still useful. As far as I know there are some standard iterator classes already implemented. Does FPC include such iterators for the various string types?

So I definitely need the IsSurrogatePair() like function then - in the case of UTF-16 encoded (UnicodeString) text. Do you know if such a function exists in the RTL? If not, I'll browse unicode.org to see what is required for such an implementation.

Same as Delphi, character.tcharacter.issurrogate() or character.issurrogate() (modern delphi units group everything as class methods in classes for some vague reason) ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

[fpc-pascal] FPC create unit path
Hi, When I try to compile a test app, I get an error saying the output folder (defined by FU) cannot be created by FPC. I suppose this behaviour is ok? Is there a way to have FPC to create the requested folder? fpc -FU.\test mytest.pp Error: Can't create object file: .\test\mytest.o (error code: 3) Fatal: Can't create object .\test\mytest.o Regards, Darius ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

I asked the same thing years back, and I was told that no, it's not the job of the compiler, but rather the job of the build script or your IDE.

Indeed. That's by design Regards, Sven ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
