About the commandline

Today's features:
  • Why the commandline rocks and GUI apps have rocks in their heads at times.

You can skip this somewhat rambling rant by going down to "CONTINUE" below.

[Note for KDE users: Konqueror has a nice konsole terminal that can be opened with F4. It's much MUCH better than Dolphin, if you're a programmer. See recent blog including 'launch' and shell-exec if you have trouble executing these files when you click on them...

Today's features:
  • Getting an address of an iterator from stl.
  • Creating a foreach() macro.
  • A couple of ways to work around unwanted C++ compiler warnings.

STL is a freaking nighmare to trace in a debugger so it's not too easy to tell what goes on in them but one thing became quite clear and that is that iterators are generic pointer types internally, which makes sense since STL needs to deal with so many different types.
