[Doxygen-develop] Open namespace-blocks in included files ignored

[Enrico S. <enr...@in...>]

Hello,

when having a directory containing

| Doxyfile ns-close.h  ns-open.h  test.cc

with

| $ cat ns-open.h     
| namespace Bar {
| 
| $ cat ns-close.h 
| }
| 
| $ cat test.cc 
| #include "ns-open.h"
|   /// A foo-class
| class Foo {};
| #include "ns-close.h"
|
| $ cat Doxyfile 
| INPUT = test.cc


the doxygen preprocessor ignores the opened namespace in 'ns-open.h':

| $ doxygen -d Preprocessor
| ...
| Reading input files...
| Preprocessing /tmp/dox1/test.cc...
| #include ns-open.h: parsing...
| #include ns-close.h: parsing...
| Preprocessor output (size: 34 bytes):
| ---------
| 00001 
| 00002   /// A foo-class
| 00003 class Foo {};
| 00004 
| 00005 
| ---------
| Read 56 bytes

Looking at the generated documentation verifies that this class is seen
as 'Foo' only but not as 'Bar::Foo'.


Using the gcc preprocessor results in:

| $ cpp -E test.cc 
| # 1 "test.cc"
| # 1 "<built-in>"
| # 1 "<command line>"
| # 1 "test.cc"
| # 1 "ns-open.h" 1
| namespace Bar {
| # 2 "test.cc" 2
| 
| class Foo {};
| # 1 "ns-close.h" 1
| }
| # 5 "test.cc" 2
