I do not understand "advanced formatting possibilities"? INF supports only BMP and MET (meta graphics). INF also supports hyperlinks via text and graphics.

I'll add OS/2 support as a feature request for fpGUI Toolkit. It's relatively easy to add new backends to fpGUI - at least much less work than LCL as far as I can see. Anyway, that will give me an excuse to dust off my copies of OS/2 2.1, Warp 3.0 Connect (still my favourite release) and Warp v4. Wow, that will bring back good memories.

One of the problematic areas are limitations related to the ancient EMX (GNU) ld linker (and also other parts of the GNU toolchain like the debugger); it would be better to switch to another linker, but that is a non-trivial task, unfortunately, because it implies many changes also in other areas). One additional area is the well-known 32-bit/16-bit thunking (support of a special calling convention necessary for invoking some of the old 16-bit API still used for console support is not available in FPC, but that is solvable using wrapper DLL like emxwrap.dll). Finally, some parts of the RTL are not debugged that well (or not even finished completely) and some FCL packages have not been ported to OS/2 yet. I'm willing to assist in solving these areas, but my time available for FPC is unfortunately rather limited and thus the progress is very slow.

INF supports One simple example - INF/IPF specifies the size in characters (see e.g. table column size). The format (IPF this time) is primarily based on the assumption of working with monospaced raster fonts (which btw makes the specification of fonts completely non-portable). There are many more examples for sure, I'd just need to dig through the documents to remember them. In any case, the limitations make the format very nice for stuff like our text mode IDE. > only BMP and MET (meta graphics). INF also supports hyperlinks via text > and graphics.

Yet again - it was fairly advanced at its time, but its age is visible now. Still, it works pretty well, it's just not that "fancy" any longer. > What I am doing at the moment is reviewing various help formats so I can > implement something that works for fpGUI based applications.

OK, that is certainly a viable approach (with its obvious limitations stemming from the fact that it becomes a new format). > I'm collecting a feature list for application help.

The licence for packages depends on the package you use. It's essentially the same as the rtl, I think, but if a package links against another library with a different licence, you may have to obey that licence and any restrictions it imposes (example: mysql).

If your application merely uses (soft link) the mysql library, then you should only be bound to the free-pascal part license. (but users of your app will have to download and install mysql themself) And this is only if the actual pascal part does not contain any mysql owned material. If you link static or plan to redistribute mysql libraries with your app, then you are bound to both licenses.

[fpc-pascal] Problem with string manager

The following cgi script shows "??" in the browser if cwstring is

there something I can change in order to work with widestrings,
cwstring and special chars? fixes_2_4 with linux.
Thanks.

Is there something I can change in order to work with widestrings, cwstring and special chars? fixes_2_4 with linux. a) bug: you are not specifying to the compiler in what code page the strings in your source code are encoded. As a result, the compiler will assume it's the default (8859-1), unless their is an UTF-8 BOM (in which case the compiler parses it as UTF-8) b) when you use cwstring, the RTL will convert any widestring you write to the current locale. Under *nix this is defined by the "LANG" environment variable (which in turn controls the various LC_* environment variables). If the current locale does not support the character you try to write, you will get question marks. I guess what's happening if you don't use cwstring and don't specify a code page, that the compiler dumps the character as it appears in the source code straight into the widestring without any conversion, and that the rtl later on extracts it (when "converting" from widestring to ansistring) also without any conversion. So it only happens to work because the code page in which you wrote the source code happens to be the same as the code page that the browser at the other side uses as default.
