Hello,
I heard that writing a complete C++ parser is very hard, but I was wondering
if Coccinelle could be made to work on C++ codebases
only handling the C subset of the language and ignoring what it does not
treat.
If the whole AST is needed than this is probably unfeasable, but if smaller
units can be handled independently then maybe very simple transformations like
renaming functions or dropping arguments could be still done, ignoring whether
the code is within a function or a method call.
The only open source C++ code transformation tool I have heard of is Pork but
it is much more difficult to set up and use than Coccinelle at the moment so
it would be nice to be able to do relatively easy things
in C++ or mixed C/C++ codebases.
I think it is possible, and indeed a C++ parser has been written that is
compatible with Coccinelle. Doing the simple case as you suggest is even
probably not too hard. But at the moment we do not have the resources to
look into it.
thanks for the prompt reply.
Is the C++ parser code available along with some documentation on how it
can be used with Coccinelle?
