CmdLineArgs - a free model application
If you need to forward the command line arguments your Ultimate++ application is started with to another application or especially a library which you do not control, this can be a problem. The target application or library might expect the command line arguments to be passed in a way complying with the C++ standard. Ultimate++ CommandLine() doesnt meet this expectation in many regards.
So I created ArgcArgv which provides int argc and char* argv[]. These variables behave exactly as the standard requires. ArgcArgv can easily be integrated in any application. CmdLineArgs shows how.
I publish the 2 files ArgcArgv.hpp and ArgcArgv.cpp which provide the solution and the 3 files CmdLineArgs.h, CmdLineArgs.lay, and main.cpp which make up the demo application as well as CmdLineArgs.upp zipped to create a single file - as an attachment to this mail hoping that this will be useful to somebody.
I declare the code, which is thoroughly commented, public domain. Still I would really appreciate if a possible user informed me of errors or any improvements.
Werner
P. S.:
The files have been updated. Please use the new package attached to message #8046.

The file won't download. It says its 0 bytes. Please post again or link me to it another way.

The forum moved some time ago. It is likely that this breaks the link.
On your request I post the package again after having updated the files (which now pay heed to "namespace Upp").
Please note that this package was one of my first misdeeds.  At that time I was an absolute Ultimate++ beginner.  Now I'm still an absolute beginner.  So use everything at your own risk.

Hi Werner,
Thanks for writing this up. I've been having problems getting a Unit Test to work with U++ - tried cppUnit and UnitTest++, which were both giving me link headaches and strange Microsoft C++ exceptions at strange memory locations.
I ended up using Fructose (a header-only implementation): http://accu.org/index.php/journals/1326, which unfortunately, required argv/argc. Luckily, your package came to the rescue.
Maybe it should be incorporated into U++ Core or some other package for people who need it! Thanks again.
Regards,
Ken

Thats strange. I have had no serious problems with UnitTest++ and using it a lot.
No compile problems. No link problems with MSVC.
I have uploaded my Upp UnitTest++ package. Just add it to the package dependencies and include UnitTest.h:
#include <UnitTest/UnitTest.h>
After this somthing like:
TEST (MyFirstTest) {
CHECK(true);
}
should work without problems.

Thanks, Ralf, for posting the package in a U++-friendly form - works great!
Not knowing to how build external libs, I was trying to build the lib under VS2005 rather than using the U++ package facility, and I think I was trying to use the UnitTest++.h header in main(). With your packaging as an example, I will know how to build external libs as U++ packages in the future.
I really appreciate your help!
Regards,
Ken

Well, I tried your UnitTest package but it didn't work for me (Your package is windows only). After that I forgot about it, and recently I made my own "Ultimatized" package of UnitTest++ sources.
This time it should work both on linux and windows.
But I did hit the original sources much harder than you with changes:
* macro CHECK is colliding with UPP macro CHECK (that's sort of stupid name for macro .. both from UPP and from UnitTest++, it's like asking for trouble)
* moved them firstly into root package directory to allow for simple #include <UnitTest++/UnitTest++.h>
* renamed files TimeHelpers.cpp to avoid duplicate filenames because it's impossible to compile such package with TheIDE ( no reaction so far in this thread from Mirek about adding "exclude from build WHEN" http://www.ultimatepp.org/forum/index.php?t=msg&th=2712& amp; amp;start=0& )
* compilation of content of those files is conditioned by flagWIN32
* moved the tests of UnitTest++ into separate package, so it looks like how I intent to use UnitTest++ package.
(I did some last minute changes today to make it work on Win32 so I'm not sure if I didn't break linux compilation, I will check @home today evening)
(Mirek please, can you take a look on this please?)
I still have one major problem on windows. The test "CrashingTestsAreReportedAsFailures" (UnitTestTest\TestTest.cpp line 64) is disabled in MINGW, so it "works" ok, but in MSC8 debug it does crash the program and TheIDE reports exception of reading from address 0. So the try {} catch block does not catch this crash. Why? Bad compiler options? U++ is stealing this exception? My windows installation is broken? Any ideas?
Under linux (Kubuntu 6.10, gcc 4.1) it works ok (166 tests passed, so also the one with crash is tested, with MINGW only 165 tests are done).
Back to my changes of UnitTest++ ... should I contact the maintainer of original project and suggest some changes which will make it easier to keep the U++ package up to date with minimal changes? I think the renaming of files is generally a good idea which will make it more portable, but rest is unlikely to happen.
And can this package be included in default U++ distribution? (after it will be maybe a tad more polished?)
http://sourceforge.net/projects/unittest-cpp/
License : MIT License
IMHO they have their own license in file COPYING, check my package, which is IMHO BSD compatible, the only restriction is the original license has to be included along with UnitTest++ package and substantial portions of it.
(argh, I broke it with my UnitTestTest package, I didn't copy the COPYING file there too ... ... sorry, I didn't think about it until now)

Of course I broke it under Linux, I forgot about some experiments in package manager...
Either in file UnitTest++/UnitTest++.upp delete line "options(!WIN32) UNITTEST_POSIX;"
or
go to package manager and remove the !WIN32 compiler option on UnitTest++ package.
I'm sorry for the inconvenience.
