Did you test the script? I'm afraid it won't work :-( I studied this couple years ago and found out that there is no way to modify the commit content from hook. See for example the discussion here: http://stackoverflow.com/questions/650168/post-commit-hook-to-update-a-file-under-version

So, it seems that we should using svn keyword? Then get correct content from it - http://svnbook.red-bean.com/en/1.4/svn.advanced.props.special.keywords.html.
What do you think?

Yes, svn keywords unfortunately don't work very well (at least for what you'd like to do) either...

The only way correct way to do this is to use external tools, usually at build time, just as the link you posted metnions.

One thing we could do, is to add a special build step into the ide package, that would check the version and modify the version.h file before building. That of course doesn't help much if the file is used from different package.

Another option would be to hardcode this behavior into theide itself. The version of sources might be exposed to any package simply by setting a macro, e.g. UPP_VERSION=8765. Similar to the build time/date macros. This value could then override the value in ide/version.h.

IMHO, the second way is better, because it is more generic and provides the version information to any package, not just theide.

What do you think? Also: Mirek, do you have any comments on this?

I never considered this too important... :)

There is also the issue that ide could be build from source not in svn.

However, I think it could be possible to extend build info. We can run svn info on main package dir if it has .svn subfolder, then add lines

#define bmSVN_REVISION 8774
#define bmSVN_URL "svn://www.ultimatepp.org/upp/trunk/uppsrc/ide"

The about dialog(s) then could #ifdef for these macros.

Later we can add GIT support there (but I am not sure what GIT informations are relevant here... :)

I'm not sure, if it is correct to write fixed values into generated Makefile. If it were used with source in svn, which were updated after the makefile was generated, it would result in incorrect information. It should be easy to take care about the corner-case and do something like (pseudocode):

if (acting on svn sources)
    svnversion $dir
else
    echo $version_generated_by_ide

It is probably ok to leave it as is for now, but I'll try to fix it soon.

Something like this should be enough for most cases when using git:

git rev-parse HEAD # shows last commit
git config --get remote.$(git config --get branch.$(git rev-parse --abbrev-ref HEAD).remote).url # shows upstream url, if available
