StringUtils, FileUtils
by Frank Heckenbach 31 May '02

31 May '02

Hi, in the current GPC version, I've included a StringUtils unit for general string handling routines (on a higher level than the built-in and RTS routines). Up to now, it only contains routines for a string hash table, but I'm planning to add some more routines. Perhaps some of you also have some routines to contribute (or features to request). Conditions for inclusion into this unit should be, IMHO: - Generally useful (not meant specifically for a certain program or something), - self-contained (not relying on an external library etc.), - new functionality compared to the existing routines (whereas the same or similar functionality under a different interface for compatibility purposes should go into other units, like GPCUtil for compatibility to `Turbo Power' units), - and, of course, compilable with the current GPC version, portable, bug-free, etc. ;-) The same goes for the FileUtils unit which has been there for some months already.

If you can repeat it, compile with another Extended Pascal compiler, for example Prospero's one. If that fails too, there is really something wrong with the code. But I suspect gpc.

operators pow and **
by Maurice Lombardi 01 Feb '02

01 Feb '02

Hi all, It seems that operators pow and ** cannot be redefined in gpc. Is that expected ? I work with djgpp / w98 dos box (should be irrelevant I think) Thanks Maurice -- Maurice Lombardi Laboratoire de Spectrometrie Physique, Universite Joseph Fourier de Grenoble, BP87 38402 Saint Martin d'Heres Cedex FRANCE Tel: 33 (0)4 76 51 47 51 Fax: 33 (0)4 76 51 45 44 mailto:Maurice.Lombardi@ujf-grenoble.fr

GPC 2.1 RC 2 released
by Frank Heckenbach 05 Jan '02

05 Jan '02

Hi everyone, GPC version 20011222, the release candidate #2 for GPC 2.1, has been uploaded to the usual places, CVS and FTP: ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/current/gpc-20011222.tar.gz The main changes made since RC 1 are in the searching of unit source and GPI files (thanks to a bug report by The Chief), the handling of packed arrays (thanks to a bug report by Emil Jerabek) and set constructors (due to some bugs found by myself). If you use any of these things, you might want to check if the changes didn't break any of your code. There is also one new "feature", the Intl (internationalization) unit by Eike Lange. (I know that normally one should not do major additions so short before a release, but the unit is completely separate from the rest of the compiler and run time system, so even a very unlikely fatal bug would not affect the stability of the whole system.) Again, I've tested it on some systems, test reports from other systems are welcome, and if you find new or especially important bugs, or very important missing features, please report them. Merry Xmas, Frank -- Frank Heckenbach, frank(a)g-n-u.de, http://fjf.gnu.de/ GPC To-Do list, latest features, fixed bugs: http://agnes.dida.physik.uni-essen.de/~gnu-pascal/todo.html

Lazy I/O
by Emil Jerabek 02 Jan '02

02 Jan '02

Accordnig to both ISO standards, readln(f) should be equivalent to get(f), when eoln(f) is true. In GPC the former seems to be implemented as lazy I/O, while the latter does not. Here is an example (enter three lines of text to test it). ---------------------------- program echo3lines(input,output); procedure copyline; begin while not eoln do begin output^:=input^; get(input); put(output) end end; begin write('Enter the first line: '); copyline; readln; writeln; write('Enter the second line: '); copyline; get(input); writeln; write('Enter the last line: '); copyline; readln; writeln end. ---------------------------------------- Is this a bug or a feature?

Hi, > sounds great! Will there be an OS/2 (emx) binary, too? I don't have the > setup for a build myself these days. Please ask on the list (gpc(a)gnu.de) I don't have an EMX setup myself, but maybe someone else does.

Interfacing C++
by Robert.Roebling＠t-online.de 23 Dec '01

23 Dec '01

Hi, I consider writing an GNU Pascal interface to a rather large C++ library. Ideally, I would like to match Pascal objects to C++ classes, either directly or indirectly. There are already Python, Perl, Basic and Lua bindings for the same C++ library, so we are not uninformed about the work involved in writing a new language binding. My question is if there is any helper tool that makes lifer for this kind of thing easier than having to do everything by hand? Thanks for any info. Please reply to me directly as I am not subscribed to the GPC mailing list - I am subscribed to too many already. The C++ library is free and Open Source, if that matters to anyone. It is the GUI library wxWindows. Regards, Robert

[Fwd: ANNOUNCE: DJGPP V2.03 Refresh Beta]
by Maurice Lombardi 20 Dec '01

20 Dec '01

Hi gpc/djgpp users I have recompiled gpc-20011202 for the "refresh" version announced below. But I have no Windows 2000 or XP machine to test it. I have only checked that it works well with W98se. It is uploaded on agnes as ftp://agnes.dida.physik.uni-essen.de/home/maurice/gpc-20011202-gcc-2953.i586-pc-msdosdjgpp-refresh.zip When running in a W98se Dos box it gives zero error (2 tests skipped as usual) when running the test suite by going into the gcc/p/test directory and issuing simply "make": this was one of the improvements announced (Nesting will recover selectors). The dostest.bat which was designed to overcome this bug by splitting the tests in chunks of 250 will no more be necessary when/if this version will be uploaded to simtelnet. Meanwhile do not use it "as is" with this version because it triggers an other bug ... apparently the maximum length of the command line which can be passed from dostest.bat to make has been somewhat decreased: it works if the tests are split in chunks of only 128 ... The following diff will do the job: --- dostest.bat.orig Thu Jan 4 07:22:08 2001 +++ dostest.bat Thu Dec 20 18:57:44 2001 @@ -28,6 +28,6 @@ if exist make.out del make.out if exist dtlist.* del dtlist.* make msg -ls -1 *.pas | split -l 250 - dtlist. +ls -1 *.pas | split -l 128 - dtlist. for %%f in (dtlist.*) do make MASK="`cat %%f`" pascal.check-long >> make.out sh test_sum < make.out This diff can be included without harm in next gpc snapshots. Meanwhile a file gpc-test-20011202.zip (with modified dostest.bat) has been uploaded to agnes in the same directory as above for people wanting to check this version of gpc with Windows 2000 / XP.

In that time a small number of bugs have been discovered and corrected. Windows 2000 and Windows XP were released with some bugs in their DOS support.

If you have a chance (or need any of the fixes mentioned) please try out the new distributions. If the distributions are an improvement over the current distributions they will replace the files on Simtel. -- Maurice Lombardi Laboratoire de Spectrometrie Physique, Universite Joseph Fourier de Grenoble, BP87 38402 Saint Martin d'Heres Cedex FRANCE Tel: 33 (0)4 76 51 47 51 Fax: 33 (0)4 76 63 54 95 mailto:Maurice.Lombardi@ujf-grenoble.fr
