tiny fart bug update: apparently it's caused by having a file called fart.class in your classpath (which obviously i do since i'm a literal child). i have no idea why defmethod is loading class files but i can't even report it since the clojure bug tracker is down!

speaking of checked exceptions, I ran across this today:

code:

/**
 * Throw even checked exceptions without being required
 * to declare them or catch them. Suggested idiom:
 * <p>
 * <code>throw sneakyThrow( some exception );</code>
 */
static public RuntimeException sneakyThrow(Throwable t) {
    // [url]http://www.mail-archive.com/javaposse@googlegroups.com/msg05984.html[/url]
	if (t == null)
		throw new NullPointerException();
	Util.<RuntimeException>sneakyThrow0(t);
	return null;
}

@SuppressWarnings("unchecked")
static private <T extends Throwable> void sneakyThrow0(Throwable t) throws T {
	throw (T) t;
}

Adventures in Clojure Day #420: Clojure has two completely different and largely incompatible systems for doing polymorphism, and the clojure community apparently prefers the less powerful of these. I seem to be the only person who thinks this is weird and dumb.

multimethods and protocols?

yeah. i understand a lot of the reasoning behind protocols, but there's no reason they couldn't have added those features into the multimethod system instead of making an entirely new one completely from scratch. also given that you can't specify a superclass in deftype/defrecord, you've pretty much got no way to do inheritance with protocols.

for better or worse ( i think better) clojure really tries to keep you from doing abstract/concrete superclass polymorphism at all costs. i actually like defprotocol/deftype myself so i guess i'm one of the dumb ones but i use a lot of spring so maybe that's why i use it so much

man, has the entire clojure community been infected with some sort of memetic virus or something? i think you're a smart guy trex, but polymorphism without inheritance has never been a thing anywhere. the only good reasons that i've seen to use protocols are speed and java interop, neither of which explains why everyone seems to regard multimethods as semi-deprecated or why protocols have to have a completely seperate syntax. they could've just made a special multimethod constructor that used java dispatch behind the scenes, but instead they decided to build an entirely seperate and redundant polymorphism system. i really don't get it

what the heck is duck typing???

duck typing doesn't force you to use inheritance, but it's still an option. clojure's protocols literally provide you with no way to specify any kind of inheritance. if you want two object to share the same behaviour you literally have to copy/past the same code.

e: literally

tef, thanks for writing what I'm thinking (mostly) since I never got around to it.

Our weedout course was 2nd year and taught in SML. Functional scared off a lot of people. Though I guess the first year course where day 1 was "this course will be using java but we wont be teaching it to you because this is CS not Programming" probably scared some people off, too.

In ours we did hoare logic and finite automata, taught by a prof with a thick finnish accent and a stutter who posted absolutely nothing online.

I'm not sure if I'd call clojure optionally typed since no actual type checking goes on. there's nothing to stop you from doing (def ^int an-int "totally not an int") for example.

e: but seriously optional typing is really the most obvious way to get the best of both worlds and i wish more languages supported it. also actionscript is optionally typed, hilariously enough.

idk dick all about DOM stuff, but you really should try to separate the mutable and immutable bits. I'd make pure functions that take and return your dom-map things and then just use swap! with them

edit:

quote:

but while in this case there's a better way to do it, the concept of passing a dereferenced version of your mutable state to a function, then changing that state to the result of the function (which is what the swap! function does) is really common in clojurescript and just feels almost like an abstracted version of object-oriented programming

yeah this, do this. idk what you mean about OOP but the biggest advantage of functional programming imo is not doing super clever map-reduce-filter bs, it's the added simplicity that immutability and pure functions/expressions give you.

Lisp's problem is loving lispers. Clojure is the "best" lisp so far and even it is riddled with bad documentation and abandoned projects. Lisp attracts smart lazy people, but I'm starting to think you need overeager jeff atwood reading idiots to answer stupid questions on stackoverflow and make lovely twitter libraries if you want a language to be successful. (srs, I like clojure but I'm becoming less and less hopeful that it'll ever be anything more than a language for people who care too much about languages)

The problem with a language that lets you just do whatever the gently caress you want is that you're stuck in a community with a bunch of people who are just doing whatever the gently caress they want.

when you're trying to mold your particular problem into the shape of a vertex shader function feeding data into a geometry shader function feeding data back into another vertex shader function which feeds data into a fragment shader function which finally writes the data as colors to a texture and that's just the first pass and it's not even given that you can read from a texture inside your vextex shader functions, I can sympathize if someone would rather just write the whole thing in C

maybe OpenCL is the answer

I used opencl once, it was pretty decent but a lot of boilerplate

prints "what", but

lua's arrays store values or references indexed by number pretty well.

a list is a sequential series of elements indexed by numbers. if you try to insert something into an index that isn't a number it should tell you to gently caress off instead of magically changing into something that sort of works like a list but isn't. if you do that then you're php level stupid.

also dijkstra thinks 1-based indexing sucks:
