The following modified version of dfilt (see the phobos std.demangle doc
for original source) with special handling of the GDB prompt allows for
dfilt to be used with gdb like so

gdb programname |dfilt

The source is

import std.stdio;
import std.ctype;
import std.demangle;

void writefl(char c) {
  writef(c); fflush(null);
}
void writefl(char[] c) {
  writef(c); fflush(null);
}

void mangprint(string line) {
  bool inword=false;
  char[] buffer;

  foreach (ch; line) {
    if (inword) {
      if (ch == '_' || isalnum(ch)) buffer ~= ch;
      else {
        inword = false;
        writefl(demangle(buffer)~ch);
      }
    } else {
      if (ch == '_' || isalpha(ch)) {
        inword=true;
        buffer=[ch];
      } else writefl(ch);
    }
  }
  if (inword) writefl(demangle(buffer));
  writefln;
}

int main() {
  char[] line;
  bool immediate=false;
  int c;

  while ((c = fgetc(stdin)) != EOF) {
    char ch=cast(char)c;
    if (immediate) {
      if (c == 10) {
        writefln;
        immediate=false;
      } else writefl(ch);
      continue;
    }
    if (c == 10) { mangprint(line); line=""; continue; }
    line ~= ch;
    if (line.length!<2 && line[$-2..$]==") ") { immediate=true;
writefl(line); line=""; continue; }
  }
  return 0;
}

Enjoy!

Eh, it's a derivative work of a part of the phobos docs ..
So I'm really not sure what applies here.
Is it even legal for me to have created this? :o
All that notwithstanding, I doubt the program is volumous enough to
warrant copyright protection. Why, it's barely more than a sniplet!
