Version 1.3.27 (In progress)

============================

|
|
Several minor changes:
|
|
|
|
- Improve the wchar_t type support
|
|
- Add a warning for when you define the 'in' typemap but
|
|
you don't define the 'typecheck' one. Very common mistake.
|
|
- Add proper default rule for function pointers, now you
|
|
can define a typemap such as:
|
|
|
|
%typemap(in) SWIGTYPE ((*)(ANY)) {...}
|
|
|
|
That will apply to all the pointer to functions. The
|
|
rule in C++ also apply to the function 'reference', ie,
|
|
in both cases
|
|
|
|
typedef int (*fptr)(int a);
|
|
typedef int (func)(int a);
|
|
|
|
This was needed since it seems to be 'illegal' in C++ to
|
|
do something like:
|
|
|
|
void *ptr = static_cast<void *>(fptr);
|
|
|
|
and probably, as for member functions, it is not
|
|
warrantied that the pointer sizes will match.
|
|
|
|
- Add the #error/#warning directives to swig's cpp.
|
|
|
|
- Add the noblock option for typemaps, which is used as
|
|
follows: supposed you a typemap, like this
|
|
|
|
|
|
%typemap(in,noblock=1) Hello {
|
|
....
|
|
}
|
|
|
|
then the typemap will be inserted without the block
|
|
imposed by the brackets, similar to
|
|
|
|
%typemap(in) Hello "...";
|
|
|
|
So, why you don't just use the quote style?, because:
|
|
|
|
1.- The quote style doesn't get preprocessed, for example
|
|
|
|
%typemap(in) Hello "$1= SWIG_macro($1);";
|
|
|
|
here, SWIG_macro doesn't get expanded
|
|
|
|
2.- Inside a quote typemap, you have to use
|
|
quotes carefully
|
|
|
|
%typemap(in) Hello "$1 = \"hello\" ";
|
|
|
|
3.- You can't make emacs and/or other editors
|
|
to indent inside a string!.
|
|
|
|
|
|
So, why do you want to remove the block?, because an extra
|
|
block when not needed (no local variables in it):
|
|
|
|
1.- makes the code harder to read
|
|
2.- makes the code larger
|
|
3.- or in short, for the same reason we have the quote style.
