Scala-tuplicity comes to 2.10

A while back I tried (and succeeded) compiling Scala 2.9.2 with increased limit on tuples.

Some time has passed, Scala 2.10 came out, and due to the recent advent of macros there could be some possibility in lifting the limit entirely - there is a thorough discussion on mailing list, but it doesn't seem to be anywhere close. So, for time being, I updated my duct-tape solution for Scala 2.10. The following script is the automated solution for generating new scala distribution with bigger tuples: 
git clone git://github.com/scala/scala.git scala-tuplicity
cd scala-tuplicity
git checkout v2.10.0
 
export ANT_OPTS="-Xmx8192m -Xss25M -Xms4096M -XX:MaxPermSize=512M"
VERS="-Dbuild.release=true -Dversion.number=2.10.0-tuplicity -Dmaven.version.number=2.10.0-tuplicity"
ant build
sed -i 's/\(val MaxTupleArity, .*\) 22/\1 55/' src/reflect/scala/reflect/internal/Definitions.scala
ant build
sed -i 's/22/55/' src/library/scala/runtime/ScalaRunTime.scala
ant build
ant replacelocker
 
sed -i 's/\(MAX_ARITY .*\) 22/\1 55/' src/build/genprod.scala
sed -i 's/import scala.language.postfixOps//' src/build/genprod.scala
echo 'genprod.main(Array("src/library/scala/"))' >> src/build/genprod.scala
scala src/build/genprod.scala
 
ant build $VERS
cd lib
cp ../build/pack/lib/* ./
for x in *.jar; do sha1sum $x | sed 's/\(\w*\)  \(.*\)/\1 ?\2/' > ${x}.desired.sha1; done
cd ..
ant fastdist-opt $VERS
And here's the proof that it actually works.

How to create your own simple 3D render engine in pure Java

Image
3D render engines that are nowdays used in games and multimedia production are breathtaking in complexity of mathematics and programming used. Results they produce are correspondingly stunning. Many developers may think that building even the simplest 3D application from scratch requires inhuman knowledge and effort, but thankfully that isn't always the case. Here I'd like to share with you how you can build your very own 3D render engine, fully capable of producing nice-looking 3D images. Why would you want to build a 3D engine? At the very least, it will really help understanding how real modern engines do their black magic. Also it is sometimes useful to add 3D rendering capabilities to your application without calling to huge external dependencies. In case of Java, that means that you can build 3D viewer app with zero dependencies (apart from Java...

Solving quadruple dependency injection problem in Angular

Angular comes with built-in dependency injection and module management system, but it can get a bit tedious to use when your project grows. Especially if you use RequireJS alongside it (a must for almost any project) and also want to be minification-safe with all those dependency injections. Let's look at a simple example with one module that provides a value and another module that prints that value: // answer.js define(["angular"], function(angular) { angular.module("the.answer") .value("TheAnswer", 42); }); // main.js define(["angular", "the.answer" ], function(angular) { angular.module("main", [ "the.answer" ]) .run([ "TheAnswer" , function( TheAnswer ) { console.log(TheAnswer); }]); }); As you can see, to provide a single dependency to my code, I had to specify it in four places (highlighted in red) - first as RequireJS dependency, then as Angular module dependency,...

Configuration objects in Scallop

It turned out that spreading type annotations throughout all the code in all places where options are requested is not a good idea. And, of course, it is prone to errors - who likes those type annotations? When using such option parsing libraries, users usually end up creating a big object with fields corresponding to each option: object Conf { var apples:Int = 0 var bananas:Int = 0 } // ... parsing options ... Conf.apples = parser.getOption("option name", ...) Conf.bananas = parser.getOption("other option name", ...) Sure, this works, and usually flexible enough - but why would anybody want to create such boilerplate? And by the way, nobody likes var's in their code :) So in Scallop , I needed to cut down that unnecessary repetition. There are several ways: Create a compiler plugin. The most powerful option. And the least enjoyable - even given the ease of installing a compiler plugin using sbt, I doubt that anybody will install compiler p...
