Here is the code that I use:

import std.stdio;
import std.ctype;

void debug_dump(ubyte[] data) {
	uint len = data.length;
	writefln("=== GOT %d BYTES:", len);
	
	for(uint offset = 0; offset < len; offset += 20) {
		uint end = offset + 20;
		if (end > len) end = len;
		
		for(uint ix = offset; ix < end; ++ix) {
			writef("%02X ", data[ix]);
		}
		
		if (offset + 20 > len) {
			char[] space = new char[3 * (offset + 20 - len)];
			space[] = ' ';
			
			writef(space);
		}
		
		writef("| ");
		
		for(uint ix = offset; ix < end; ++ix) {
			if (isprint(data[ix])) {
				writef("%s", cast(char) data[ix]);
			} else {
				writef(".");
			}
		}
		
		writefln();
	}

	writefln();
}
