<@ToxicFrog>
Argh. My brain doesn't want to bend this way.
15:31
<@Vornicus>
??
15:31
<@ToxicFrog>
I'm fiddling with my OO library.
15:32
<@ToxicFrog>
Class is an instance of itself.
15:33 * Pi points and laughs at ToxicFrog
15:33
<@Vornicus>
ah, well
15:36
<@Pi>
I suppose it depends on the language, but the only class I can imagine would meet that criterion would be Type.
15:36
<@ToxicFrog>
Smalltalk does that as well, I believe.
15:36
<@ToxicFrog>
In any case, this is Lua.
15:36
<@Pi>
Why do you hate yourself?
15:36
<@Vornicus>
Java's Class class does that.
15:37
<@ToxicFrog>
If I hated myself I would be doing this in Perl~
15:37
<@Vornicus>
Usually you get this kind of wackiness in the foundational classes, in particular Class and Object.
15:37
<@ToxicFrog>
I haven't even looked at implementing Object yet.
15:38
<@ToxicFrog>
But I should, actually.
15:38
<@ToxicFrog>
Since in theory it should go Object->Class
15:38
<@Vornicus>
(Class is an instance of itself, and inherits from Object; Object is an instance of Class.)
15:38
<@ToxicFrog>
(which would also solve my issues with instanceof)
15:38
<@Pi>
With Object, the class is actually an instance of a derived class.
15:38
<@ToxicFrog>
The problem here is that Object is also an instance of Class, which is a subclass of Object
15:38 * ToxicFrog wraps his head with duct tape to keep it from exploding
15:41
<@Vornicus>
Then there's the madness with thenumeric class hierarchy - though most languages don't touch that.
15:42
<@ToxicFrog>
"numeric class heirarchy"?
15:42
<@Vornicus>
Integer extends Rational extends Real extends Complex.
15:42
<@ToxicFrog>
Aah.
15:43
<@ToxicFrog>
Yeah, not going there. If someone wants complex numbers they can write their own classes for same~
15:50 * TheWatcher eyes his assert replacement, stabs it
15:51
<@TheWatcher>
Why doth thou not work, thee accursed pile of misbegotten code?
15:51
< GeekSoldier>
it's not assertive enough?

15:53 * TheWatcher bleghs, breaks out gdb
15:55
<@ToxicFrog|W`rkn>
...hmm. I have a bad feeling about this.
15:56
<@ToxicFrog|W`rkn>
Oh, awesome.
15:56
<@ToxicFrog|W`rkn>
Lua will detect loops in __index.
16:08
<@Vornicus>
loops?
16:09
<@Vornicus>
What specific kind of loop is this?
16:10
<@ToxicFrog|W`rkn>
If, say, a's __index refers to b, b's __index refers to c, and c's __index refers to a.
16:10
<@ToxicFrog|W`rkn>
Without loop detection, asking for a field in any of those tables that exists in none of them would livelock the program.
16:10
<@Vornicus>
what's __index do? Obviously I missed that bit.
16:10
<@Vornicus>
aha
16:11
<@ToxicFrog|W`rkn>
The fallback for the table index operator []. If you ask for a field that doesn't exist and the table has an __index metamethod, it uses that instead.
16:11
<@Vornicus>
aha
16:11
<@ToxicFrog|W`rkn>
> o = {}; c = {}
16:11
<@ToxicFrog|W`rkn>
> setmetatable(o, { __index = c }); setmetatable(c, { __index = o })
16:11
<@ToxicFrog|W`rkn>
> print(o.foo)
16:11
<@ToxicFrog|W`rkn>
stdin:1: loop in gettable

<@ToxicFrog|W`rkn>
It's full of morons.
20:55
<@ToxicFrog|W`rkn>
I would love to have someone come in and ask a question that doesn't boil down to "please teach me how to use the Lua<->C API, because I'm too lazy to read chapter 3 myself"
21:10
<@Vornicus>
ah
21:10
<@Vornicus>
Remind me, I need to learn the Lua<->C API at some point.
21:10
<@Vornicus>
But for some reason last time I couldn't wrap my head around Lua at all.
21:18
<@ToxicFrog|W`rkn>
o.O
21:18
<@ToxicFrog|W`rkn>
It's such a small language, though!
21:19
<@ToxicFrog|W`rkn>
And the API is fairly large, but most of that is type bloat; conceptually it's very simple.
21:20
<@Vornicus>
The manual was totally opaque, is the problem I had.
21:21
<@ToxicFrog|W`rkn>
This statement fills me with confusion.
21:21
<@ToxicFrog|W`rkn>
I think we've had this conversation before, and it filled me with confusion then too.
21:23
<@Vornicus>
Then there's the whole "globals by default" thing, which is quite frankly the stupidest of all possible language design decisions ever.
21:24
<@ToxicFrog|W`rkn>
I disagree, but it is slightly annoying.
21:25
<@Vornicus>
well, okay, systems-hungarian warts in a scripting language is pretty bad too.
21:25
<@ToxicFrog|W`rkn>
1-indexed arrays are vastly worse than globals by default, but still not the worst design decision ever,.
21:26
<@Vornicus>
I don't see too much problem with 1-indexed arrays, personally.
21:30
<@Vornicus>
Though this is probably my math bias talking, where 1-indexing is approximately as common as 0-indexing, and the choice is made for readability.
21:30
<@ToxicFrog|W`rkn>
Zero-indexing makes a bunch of stuff easier, none of which I can think of at the moment~
21:31
<@Vornicus>
index <-> pointer conversion
21:31
<@ToxicFrog|W`rkn>
Other than that.
21:31
<@ToxicFrog|W`rkn>
Which is irrelevant in Lua,.
21:32 * ToxicFrog|W`rkn wraps his head in more duct tape
21:32
<@Vornicus>
(which I once brought down a professor on. Fucker was incompetent, and it was my first chance to prove that he didn't know what he was talking about)
21:37 * Vornicus tries some things.
21:39
<@Vornicus>
Heap invariant... 0: heap[n] < {heap[2n+1], heap[2n+2]}; 1: heap[n] < {heap[2n], heap[2n+1]}... nothing particularly useful there...
21:41
<@Vornicus>
iteration: for (k = 0; k < len; k++); for (k = 1; k <= len; k++)... nope.
21:42
<@Vornicus>
null-termination strlen(): 0: while(str[k]) k++; return k .... 1: while(str[k]) k++; return k - 1 .... okay that's a little bit more elegant with 0 indexing...
21:44
<@ToxicFrog|W`rkn>
Argh. There was something just this weekend where I was thinking "goddamnit, this would be easier with 0-indexing", but now I can't remember what it was.
21:46 * ToxicFrog|W`rkn flails at this OO library

22:12
<@Vornicus>
silliness
22:12
<@jerith>
Useful, though.
22:13
<@jerith>
Well, useful if you have a dir full of files and want to choose a random one.
22:13
<@Vornicus>
...now this indexing thing is gonna gnaw at me.
22:14 * jerith gnaws on Vorn as well.
22:15
<@Vornicus>
gah
22:15 * Vornicus throws jerith off the earth
22:16

Ooh, can you do that with commercial payloads as well?
22:17 * Vornicus throws jerith's mining drone off the earth.
22:18 * jerith starts "jerith Orbital Insertion, plc" and employs Vorn.
22:19 * Vornicus flargs

22:21 * jerith diversifies.

Now, where to find German midget astronauts...
22:24
<@gnolam>
That's easy. Getting the donkey up there, now /that's/ the tough part.
22:24
<@jerith>
As long as it's a small donkey.
22:24
<@jerith>
We know Vorn can already lauch a 108kg payload.
22:25
<@jerith>
I suppose we could lauch the donkey in parts and have the midgets put it together in orbit...
22:28 * gnolam laughs out loud.
