But personally, when I write C++ code, I never use namespace. I
always prefix my class name(and corresponding source file names) with
proper module name, and put the all source files of a module in its
dedicated sub-directory . This make class name globally unique
throughout the project, and facilitate further re-factoring(searching
and replacing).
I find that rather a horrible substitute for proper use of namespaces.
I know it is common, partly because that's what you have to do in C,
and partly because namespac3es were added late
When using namespace, people can and tend to use the same name in
different namespaces, this seems like a advantage, but I see it as a
disadvantage.
I think that is a seriously misguided position. There is a good reason
for adding namespaces (Ada has always had this kind of capability in
the form of packages, and the package concept in Ada is, to Ada
programmers, one of its most powerful features). Since you never use
namespaces, it is not surprising that you do not appreicate their
importance.
To me, the ability to make extensive use of namespaces is one of
the strong arguments for switching to C++
If you want to change a name in one namespace to some
other more accurate/proper name, you use some search tools to search
all the references of the name, you will find that the name is
probably also used in other namespaces, so you just can't use "replace
all" command to replace all references with the new name, you must
manually replace them one by one. Is this what you want ?.
You use proper tools that do the replacement just of references to
the entity whose name you want to change. It is often the case that
people avoid use of features because of a lack of proper tools, but
certainly there are tools that can do this kind of intelligent
replacement (GPS from AdaCore is one such example, but we certainly
wouldn't suggest it was unique in this respect!)
