Eclipse-CDT: Use Namespace in automatic generated include-guards

Question

Is it possible (and how) to add the namespace in the name of the automatic generated include guards in Eclipse CDT, when creating a new class using the .hpp/.cpp templates?<

Answer 1

So in the Preferences dialog under C/C++ -> Code Style -> Code Templates you can modify the template to be closer to what you need, for example if you need the namespace in the guard, you can do something like.

${filecomment}

#ifndef ${namespace_name}_${include_guard_symbol}
#define ${namespace_name}_${include_guard_symbol}

${includes}

${namespace_begin}

${declarations}

${namespace_end}

#endif /* ${namespace_name}_${include_guard_symbol} */`

Answer 2

There's a hidden preference you can set to get at least the file's path or a uuid in there instead of just CLASSNAME_H_. See my full answer here.
