name string: the mangled name

Return Value

Type: string

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

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

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