Do you have a pointer for that function in dmd ?
The compiler doesn't do it as one function, I mean it can parse
as string and mangle it in the process of compiling code.
To go from demangled string => mangled string, you'd first parse
the demangled string as a declaration and turn it into a symbol,
then mangle that symbol.
But.... if you just want to do really simple cases, maybe this
isn't too hard. I just quickly slapped this file together:
http://arsdnet.net/dcode/mangle.d
It is very basic, but might work for a lot of cases - it handled
some basic functions I tried. Perhaps not too hard to add support
for more from here.
As you can see by looking at the code, the way it works is:
1) tokenize the input string (it does this in a stupid way, and
doesn't know all of D's symbols and keywords, but it doesn't have
to be too smart since demangle produces fairly predictable input,
so I think it will be ok).
2) runs a simple, stupid parser to get the components of the
function - return type, name, and arguments. To add support for
templates, extern(C), and so on, this would need to be expanded.
3) put the pieces back together in a wholly mangled form,
borrowing one helper array from core.demangle.
There's a main function at the bottom of the file that does one
of the few tests I tried with it.
