constexpr and decltype parsing #125
Conversation
Parses constexpr (in the manner of const) and decltype (in the manner of __typeof). Adds flags for them and also for other already parsed items (mutual, auto). Signed-off-by: John Bowler <jbowler@acm.org>

Thank! Seems to be ok, as far as I can see, though I may miss something of course. The proof of the pudding... @usiems - please have a look at this, too.

Note that, if new keywords are, for our purposes, equivalent to recognized ones, one might probably as well add a #define to the pp-qt-configuration file. The embedded preprocessor should not care.
Not directly related to this commit, but because support for auto was prepared in the code:
If auto is used for return types in the Qt headers, the generator has a problem, because the parser will not automatically derive the returned type, which in turn means that the correct code can't be generated.
This should be seldom be the case in Qt though, since this would mean that a method implementation is in the header file, which would somewhat defeat the promised stable binary interface. The only valid use case would be for templated container types, which PythonQt doesn't wrap anyway. Still, something we should be aware of.

It is used in that way in Qt6.5.3, which is why I added it. It's like decltype() or __typeof(). Typeof is ignored which means the type will be wrong. 'auto' might work if preserved. I simply don't use C++ class auto so I'm not familiar with the restrictions. decltype is likely to occur in templates (function templates maybe) which are not currently handled. No problem until Qt6 then the function will just have to be disabled in the relevant typesystem file. I added auto mainly so I could add big warning message when it is encountered. |
