A similar D code is, as far as I know,
type.field.offsetof
Is there an any way to make a corresponding D template?
What you've written is the specific syntax for offsetof in D.
If the intent is to create a template so that you can simply
find/replace offsetof(type,field) with
offsetoftemplate!(type,field) then I think it is easier to create
a sed script - better yet a D program - for replacing the C macro
with D code.
Example program:
import std.array;
import std.file;
import std.regex;
import std.string;
int main(string[] args)
{
if (args.length < 2)
return -1;
auto regex = ctRegex!(`offsetof\(([^,]+),([^)]+)\)`);
auto sink = appender!(char[])();
foreach (filename; args[1..$])
{
auto text = readText(filename);
sink.reserve(text.length);
replaceAllInto!(cap =>
cap[1].strip~"."~cap[2].strip~".offsetof")(sink, text, regex);
write(filename, sink.data);
sink.clear();
}
return 0;
}
