C++ code parser...

Does anyone know of a class that parses C/C++ code (like the classview tree in VS)?

Parse how? You mean a lexer?

I'm not sure what it's called else I would have googled it.... I want to extract structs, typedefs, classes, externs, globals, etc. the same way the class-view tree does in Visual Studio. I don't know what the act of doing such is called, other than "parsing".

Man, that's not a trivial thing to do.

To start you'll need a lexer -- takes text and determines if it's valid C++. This alone takes some doing, cause C++ isn't the most syntactically pretty language around. Don't try and do it yourself or you'll die of old age; instead, write a grammer and lean on a lexer.

Then you'll need a parser; it takes the output from a lexer and typically gives you a structure tree.

Grab the dragon book and read about compiler construction; you're building the first two or three stages of one.

For available tools, try lex, yacc, and bison.

Parsing C++ is insanely difficult.

You could try hacking the gcc parser (hard) or maybe take a look at this[^]. It's a long time since I looked at PCCTS but IIRC, it seemed to work Smile | :)

I use CCCC[^] for metrics sometimes and that has a parser as well.

sorting a list

Hello,

I have a list control item with a given amount of columns and respective headers. I would now like to add some sorting functionality, where, upon clicking the header of the respective column, it sorts alphabetically. Are there any functions to accomplish this?

FarPointer13-Jul-06 8:45

BOOL SortItems(<br />
   PFNLVCOMPARE pfnCompare,<br />
   DWORD_PTR dwData <br />
);

You'll have to create a compare function to handle how it will sort the items, but after that you can just call SortItems. See the MSDN documentation for details and an example.

okay but what action item will take care of the header clicking functionality, because from there I can call sorting method.

In your CListView/CListCtrl-derived class, provide a handler for the HDN_ITEMCLICK notification. Call the SortItems() method from there. See here for more.

Well to first add the notification for HDN_ITEMCLICK is tough:-
why because the on notify macro is as follows
ON_NOTIFY( wNotifyCode, id, memberFxn ) and the id of the header control is zero unless explicitly set .

Compared to what, chewing gum? It gets added to the message map just like any other. How's that tough?

Yeah, so?

FarPointer wrote:

Of course it's zero, and has been since the control's inception. Why would it need to be anything else?
