6502 / createElement.js
Created October 24, 2016 08:41
Utility to create a DOM element with prescribed style, parent and content (e.g. x=e("div#mydiv.myclass", {s_border:"solid 1px #000"}, "textnode", e("#inner")))
function e(type, opts) {
var i;
if (!opts) opts = {};
i = type.indexOf(".");
if (i >= 0) { opts.className = type.slice(i+1); type = type.slice(0, i); }
i = type.indexOf("#");
if (i >= 0) { opts.id = type.slice(i+1); type = type.slice(0, i); }
var d = document.createElement(type||"div");
if (opts.className) d.className = opts.className;
if (opts.id) d.id = opts.id;

A simple logging facility

6502 / refcount.h
Created October 23, 2016 21:09
A simple intrusive reference counter approach (referenced instances must have a `refcount` integer but don't need to derive from `RefCounted`)
#if !defined(REFCOUNT_H_INCLUDED)
#define REFCOUNT_H_INCLUDED
#include <atomic>
#include <algorithm>
struct RefCounted {
std::atomic_int refcount;
RefCounted() : refcount(0) {}
};

Last active October 23, 2016 20:35
Reasonable string formatting for C++ (requires C++11)
#include <stdarg.c>
#include <string>
#include <vector>
std::string stringf(const char *fmt, ...) {
std::vector<char> buffer(256);
va_list args, cp;
va_start(args, fmt);
va_copy(cp, args);
int sz = vsnprintf(&buffer[0], buffer.size(), fmt, args);
