string demangle(string name);
Demangle D mangled names.
If it is not a D mangled name, it returns its argument name.

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

import core.stdc.stdio : stdin;
import std.stdio;
import std.ascii;
import std.demangle;

void test(int x, float y) { }

int main()
{
    string buffer;
    bool inword;
    int c;

    writefln("Try typing in: %s", test.mangleof);
    while ((c = fgetc(stdin)) != EOF)
    {
        if (inword)
        {
            if (c == '_' || isAlphaNum(c))
                buffer ~= cast(char) c;
            else
            {
                inword = false;
                write(demangle(buffer), cast(char) c);
            }
        }
        else
        {   if (c == '_' || isAlpha(c))
            {
                inword = true;
                buffer.length = 0;
                buffer ~= cast(char) c;
            }
            else
                write(cast(char) c);
        }
    }
    if (inword)
        write(demangle(buffer));
    return 0;
}
