std.demangle

pure nothrow @safe string demangle(string name);

Demangle D mangled names.

Parameters:

string name

the mangled name

Returns:

A string. If it is not a D mangled name, it returns its argument name.

Examples:

// int b in module a
writeln(demangle("_D1a1bi")); // "int a.b"
// char array foo in module test
writeln(demangle("_D4test3fooAa")); // "char[] test.foo"

Examples:

This program reads standard in and writes it to standard out, pretty-printing any found D mangled names.
