axefrog / build.ps1
Last active August 29, 2015 14:14
A simple MSVC++ build script for my game development. Supports an arbitrary source folder structure and command arguments for running the built file and optionally starting the debugger.
$postbuild = ""
foreach ($arg in $args) {
switch ($arg) {
"run" { $postbuild = "run" }
"debug" { $postbuild = "debug" }
}
}
if (!(test-path build)) { mkdir build }
if (!(test-path build/obj)) { mkdir build/obj }

Planning out a font atlas
std::shared_ptr<FontAtlas> generateFontAtlas(int fontId, int fontSizeInPixels, int sdfPadding)
{
/* ACTION PLAN:
create a new list (vector) in which to stage a set of character glyphs, each prepared in isolation
for each character:
load the character and its metrics from the font engine, using a very large font size (10 times the requested font size)
create a new image expanded to include padding for the distance field
copy the character bitmap into the centre of the image
render the distance field into the image
downsize the image

axefrog / scope.js
Last active August 31, 2015 19:14
An idea for scoping Cycle.js child components/dialogues in the context of their parent. Any driver can optionally supply a scope() function, which returns a scoped instance of itself. A driver can also supply an unscope() function which returns a transformed instance of its associated sink. Anything that is scope-unaware is preserved.
function runInScope(main, sources, context, ...args) {
if(!main) {
throw new Error('A "main" function must be supplied, which will be called in scope and from which a (sinks) object will be returned');
}
if(!sources) {
throw new Error('A source drivers object must be supplied, to which scoping can be applied');
}
if(!context) {
throw new Error('A scope context object must be supplied, either as a string, or as an object of key/value pairs');
}

Simple logger for my Cycle.js apps. Writes pretty console output and exposes an observable message stream if further processing is desired.
import logger from './logger';
let log = logger('Category');
log.trace('Just tracing stuff');
log.debug('Here is a debug message');
log.success('The successful thing happened that we wanted to happen');
log.info('Information makes the world go around, and here is that string:', str);
log('An info message can be logged using short form');
log.warn('You better be careful about this kind of thing');

Power Shell make script I wrote for my game project; can be easily adapted for other projects too. Note: BUILDING_DLL #define is used for DLLs, for use with __declspec import/export switching. I've included an example header file that illustrates this.

jQuery plugin that allows any sequence of block elements to become sortable by dragging. Inserts a drag handle element into each item if one is not provided.

axefrog / computeArrayUpdateOperations.js
Last active December 20, 2015 22:09
A JavaScript algorithm I came up with to calculate the operations to be applied to an array L to make it the same as a new array R when it is undesirable to simply replace L with R. Typically this is when doing so is a costly operation (such as when the elements represent the items of a DOM collection) and/or each component of the update require…
// both arrays should be presorted
function computeArrayUpdateOperations(oldarr, newarr, compare) {
if (!compare)
compare = computeArrayUpdateOperations.compare;
var l = 0, r = 0, p = 0,
op = null, ops = [],
leof = l >= oldarr.length, reof = r >= newarr.length;
while (!(leof && reof)) {
if (!leof && (reof || compare(oldarr[l], newarr[r]) < 0)) {
if (op && op[0] === 'i')
