Hi, I'm pinging back about this patch : * libclang: Add three functions useful for dealing with anonymous fields. +clang_Cursor_getOffsetOfField +clang_Cursor_isAnonymous +clang_Type_visitFields
Currently, there is no function in libclang to access clang logic that
handles anonymous members in a record.
Given the current API , there is no direct method to :
a) recover the offset of an anonymous field.
- displayname == spelling == '', clang_Type_getOffset does not work
+ new clang_Cursor_getOffsetOfField will expose that information
b) clearly identify that DECL as an anonymous record.
+ new clang_Cursor_isAnonymous will expose that information
When using clang_visitChildren, an anonymous member will be returned
as a STRUCT_DECL/UNION_DECL.
Currently the libclang user has to re-implement the logic to
differentiate FIELD_DECL in the list of children nodes
For example,
struct A {
struct {int a;} typeanon;
struct {
int bariton;
union {
int foo;
int foo2;
};
};
int c;
} ;
Some children are STRUCT_DECL, some are FIELD_DECL, some are attributes.
Worse,
children[0] == STRUCT_DECL (struct {int a;})
children[1] == FIELD_DECL (typeanon)
children[2] == STRUCT_DECL (anonymous structure)
children[3] == FIELD_DECL (int c)
Sometime a STRUCT_DECL is a field (children[2]) sometimes it is just a
STRUCT_DECL.
The new function clang_Type_visitFields will expose the existing
libclang capabilities to list only fields, and not all children node,
as does clang_visitChildren.
fields[0] == FIELD_DECL (first structure - typeanon)
fields[1] == FIELD_DECL (second anonymous structure)
fields[2] == FIELD_DECL (int c)
