jasononeil / Module1.hx
Created September 6, 2013 02:16
**Compile to separate JS Files in Haxe** In this example 1) SharedCode is compiled to sharedcode.js and must be loaded first 2) Both Module1 and Module2 reference SharedCode, but do not duplicate it's code. Look at the resulting Javascript to see the output. You would have to ensure sharedcode.js is loaded before either of the module javascript …
class Module1
{
static function main() {
SharedCode.greet("Jason");
}
}

jasononeil / TraceMemberMethod.hx
Created September 15, 2013 10:13
In Haxe, a member trace() method does not have priority over the haxe.Log.trace()
import haxe.PosInfos;
class TraceMemberMethod
{
static function main() new TraceMemberMethod();
public function new() {
messages = [];
trace( "hey" ); // Uses haxe.Log.trace()

jasononeil / AbstractExample.hx
Last active December 27, 2015 15:48
Really simple example of abstracts - creating an "extension" of AnchorElement with a custom constructor. Uses all inline code, and shows how implicit casts can be used when interacting with API that expects the underlying type.
// Compile with `haxe -js AbstractExample.js -dce full -main AbstractExample.hx`
import js.html.AnchorElement;
class AbstractExample {
static function main() {
var myAnchor = new MyAnchor( "http://google.com", "Click here!" );
expectsAnchor( myAnchor ); // Notice how it automatically casts back down to AnchorElement
}

`AcceptEither`, a way to accept either one type or another, without resorting to "Dynamic", and still have the compiler type-check everything and make sure you correctly handle every situation.
class Test {
static function main(){
stringOrInt( "hello" );
stringOrInt( 10 );
}
static function stringOrInt( either:AcceptEither<String,Int> ) {
switch either.type {
case Left(str): trace("string: "+str);
case Right(int): trace("int: "+int);

jasononeil / ReflectionCost.hx
Created June 12, 2016 12:24
Demonstrate how much extra code reflection (Reflect.* and Type.*) generate in Haxe code
class ReflectionCost {
public static function main() {
var obj = new ReflectionCost();
#if reflect
Reflect.setField( obj, "name", "Jason" );
Reflect.callMethod( obj, Reflect.field(obj, "printName"), [] );
Type.getInstanceFields( Type.getClass(obj) );
#else
obj.name = "Jason";
obj.printName();

Last active November 10, 2016 11:16
Demonstration of using Haxe abstracts to take care of explicit conversions between different units of measurement, with no performance overhead.
class Metric {
static function main() {
var coinRadius:Millimeters = 12;
var myHeight:Centimeters = 180;
var raceLength:Meters = 200;
var commuteDistance:Kilometers = 23;
diff( coinRadius, myHeight ); // 1.788 meters
diff( raceLength, commuteDistance ); // 22800 meters
sum( commuteDistance, coinRadius ); // 23000.012 meters

Last active June 5, 2017 23:33
A webpack loader that compiles (and watches) a hxml file, including the resulting JS in the webpack bundle.
import haxe.macro.Context;
import haxe.macro.Type;
import haxe.macro.Expr;
import sys.io.File;
class WebpackLoaderUtil {
public static function outputJson(outputFile:String) {
Context.onGenerate(function (types:Array<Type>) {
var allFilesUsed = [];
for (type in types) {

List of all Sitespeed 4.0 metrics. I couldn't find this list anywhere, and it took me a while to figure out how to generate the file using grunt-sitespeedio (for future reference: set `sitespeedio.default.options.metrics.list=true`). I figure pasting this here will help some other poor souls thanks to the SEO goodness.

ClassicSwitch.hx - a macro which takes a switch statement and turns it into an if/elseif/else chain. This is useful if you want traditional ecmascript "switch" behaviour, not the kick-ass haxe pattern matching. See the README, the implementation, and some tests below.
import haxe.macro.Expr;
import haxe.macro.Context;
class ClassicSwitch
{
macro static public function from(inExpr:Expr):Expr
{
var retExpr:Expr = null;
switch (inExpr.expr)
