I understand that I can add my special suffix, but what I really want is to
process c++ files but have each tag point back to the original pre-processed
file via the embedded #line directives:
/v/main/src/myclass.pre -special syntax c++
eg:
CLASSDECL myclass
CONSTRUCTOR myclass
ENDCLASSDECL
/v/main/work/myclass.cxx - plain c++ with #line directives pointing back to
myclass.pre
eg:
#line 1 "/v/main/src/myclass.pre"
class myclass {
public:
#line 2 "/v/main/src/myclass.pre"
myclass();
#line 3 "/v/main/src/myclass.pre"
}
So I run gtags on myclass.cxx, which generates tags properly, but i want all
the tags to respect the #line directives for file & line information in the
tags file.
so that tag:
myclass::myclass() ---> myclass.pre, line 2
instead of myclass.cxx, line 5
Thanks!
