colomon jnthn++ # awesome day of hacking. 00:00
jnthn 'twas fun. :-) 00:04
colomon I'm trying to build everything now, don't know if I'll have a proper chance to take a look at it tonight. 00:06
We've been watching Life on Mars (BBC) with a friend who's coming over in about an hour for the next episode. :)

eternaleye __rnddim__: See ^^^ 00:11
jnthn colomon: Nice. :-)
colomon: No worries about not getting more done today. There's tomorrow, and the day after, and... :-)
colomon :)
jnthn colomon: Is there anything you'd especially like me to look at? I can likely give Perl 6 a few hours tomorrow.
colomon hmmm.... 00:12
jnthn I'll probably try and { x => 42, ... } style hash constructors in place.
and .keys, .values, .kv on EnumMap
(and thus Hash)
But those shouldn't take long. 00:13
colomon I'd still be in heaven if my ($a, $b) = (1, 2) worked, and sub always dispatched to the right type....
but I understand the first of those is more pmichaud's area...
and the second is super hard. 00:14
jnthn Yeah, I'd like that to work too.
colomon Do enums work after what you've done today?
jnthn No
Enum is just the name for "immutable Pair" really.
And EnumMap for "immutable Hash"
Though they're both needed for making enums work. 00:15
On list assignment - I can try and work out why it doesn't work. I thought Pm had done it...
colomon maybe I missed it.
jnthn It may be an easy-ish fix.
colomon ng: my ($a, $b) = (1, 2);
p6eval ng aa0a08: ( no output ) 00:16
colomon ng: my ($a, $b) = (1, 2); say $a; say $b

ng aa0a08: OUTPUT«Mu()␤»
jnthn :-/
colomon yeah, that.
jnthn ng: my ($a, $b); ($a, $b) = (1, 2); say $a; say $b;
colomon he had it working at one point (though "my" didn't work in conjunction with it) but it broke again in his last round of changes.
p6eval ng aa0a08: OUTPUT«Mu()␤Mu()␤»
jnthn ng: my ($a, $b); list($a, $b) = (1, 2); say $a; say $b;
p6eval ng aa0a08: OUTPUT«Cannot assign to readonly value␤current instr.: '&infix:<=>' pc 14862 (src/builtins/Junction.pir:113)␤» 00:17
jnthn meh.
OK, certainly br0ken.
colomon Getting that working would be really nice for a bunch of numeric stuff. :)
jnthn Yeah
colomon BTW, S32-str/index.t is broken now? 00:18
jnthn I'll take a look and see if I can work out what's wrong.
Oh?
I didn't notice that. :-/
colomon looks like it's dying before the last three tests?
jnthn I knew I'd broken that whitespace one...
colomon That's all I can think of off the top of my head, I've got to get my boy in the bath ASAP here. 00:19
jnthn colomon: It runs all tests here. Odd. :-/
OK, I'm going for sleep in a moment too...it's late here.
colomon Good night!
jnthn night! o/ 00:20
huf jnthn: well yeah, i'm slightly insane so i know it's not fun 00:47
... only very slightly tho ;)

diakopter best spam Subject: ever: I have redesigned your website! 00:52
__rnddim__ I'm back after only 2 hours! Now, can someone point me to rakudo and ng source code? :} 00:55
mberends rakudo.org 00:56
__rnddim__ feels stupid for not checking that first. 00:57
mberends :) you'll need a bit of git-fu to switch branches from master to ng 00:58
__rnddim__ I'll start on all that in a minute.
__rnddim__ does not know what to do. He is screaming into the 5th dimension. 01:09
diakopter can't perceive the 5th dimension 01:10
mberends Step 1: DON'T PANIC!
__rnddim__ Step 2: IGNORE STEP ONE!!!!
__rnddim__ is now screaming in 7 dimensions.
__rnddim__ is now screaming in .25 dimensions. All is calm. 01:12
mberends redirects the 5th, 6th and 7th dimensions to /dev/null
__rnddim__ You destroyed probability and existence!? Noes! (I have this theory where 4d is time, 5d is probability, and 6d is existence) 01:15
lisppaste3 mberends pasted "faulty unlink() for jnthn to nitpick" at paste.lisp.org/display/94502 01:16
mberends oops. redirect.rollback() 01:17
__rnddim__ So... should I just sign up a github, download ng branch, and upload patches? Or get a 'commit bit(?)'? Or... 01:19
Recommended course of action, please.
mberends __rnddim__: only get a github account if you want to break, er, program Rakudo 01:20
read-only access is publicly available 01:21
commit bits usually come to people who've submitted a few nice patches via that paste site 01:22
__rnddim__ by paste site, do you mean something like paste.lisp.org?
mberends yes
__rnddim__ so, for now at least, if I fix something (base 16 conversion in ng, for example), should I put it on a place like paste.lisp.org? 01:23
mberends that's right, and the others with commit bits will test it out and commit it for you 01:24
__rnddim__ alrighty.
__rnddim__ will download ng branch.
mberends you may find www.gitready.com/ useful 01:25

quietfanatic I don't know if it's supposed to do that, but it's kinda surprising 01:50
__rnddim__ I think 'git checkout ng' might work, but I haven't tried it. 01:52

__rnddim__ It says: error: pathspec 'ng' did not match any file(s) known to git. 01:54
colomon git checkout -t ng
?
I can never remember 01:55
__rnddim__ git checkout -t ng said missing branch, try -b.
git checkout -t -b ng is working...
Here's what it said: Switched to new branch ng. I'm not an expert, but seems to have worked. 01:56
diakopter "new branch"? 01:57
as in, it created a local branch with that name?
__rnddim__ git branch shows this: master \n * ng 01:58
I think it said new branch because I didn't have it before.

git clone [directory] -b ng seems promising... 02:36
__rnddim__ is still finding out how to get the ng branch :( 02:43
PerlJam __rnddim__: once you have a clone of rakudo, you have the ng branch as a remote. To make a local branch that tracks the remote you do: git co -b ng -t origin/ng
__rnddim__ let me try that.
PerlJam __rnddim__: sorry, "co" is my shortcut for "checkout", so use "checkout" where I have "co" 02:44

colomon jnthn: It would probably be better to make a specific Iterator type for IO, but the question of exactly how to do that is kind of funky. This gather / take implementation should work fine in the meantime.

colomon and after I added Str.Int and that tested passed, now I get
Method 'e' not found for invocant of class 'Str'
ah, that's $filename !~~ :e 14:56
okay, can fudge that. 14:58

jnthn mberends: They are Parrot ops, so see the Parrot opcode docs for names and what register types they want. 15:13
colomon needs an embarrassed to admit that smiley.

mberends it's not II, NI or IN :(
jnthn mberends: Yes, it has no result, so you need a v (= void) first.
mberends: The first char always represents what the opcode "returns", as it were. 15:15
mberends thanks. sleep.t expects sleep() to return how long it akshually slept
got that, never thought about lowercase v
jnthn heh heh 15:16
From sys.ops:

goto ADDRESS(handler);

mberends aw, no time travel :(
jnthn mberends: Well, if you want, to complain about that, trac.parrot.org ;-) 15:17

15:18 xomas_ left
jnthn pir::time__N() 15:18

Puts the current system time (represented as a number of seconds, with
microseconds) in $1.
(the time opcode)
mberends: Or do you mean, what Perl 6's sleep should return?
mberends will do a subtract and return seconds.microseconds 15:20
jnthn That sounds sane.
mberends the test expects a value back, either int on num would do
but returning the int you gave it is lame 15:21
jnthn Yeah, it is. :-)
mberends "I went for an hour's snooze, and woke up 100 years later..."
colomon thinks his Str.Int push made it through to github just before github went down.... 15:22

mathw indeed
masak that's quite an honour.
mathw and thus it's highly appropriate that Haskell programmers make extensive use of currying
masak it's like someone would name a language 'Carl' and then a language feature 'masaking'. 17:38

__rnddim__ right now I'm running make.
Hello to you to. 17:48
colomon masak: nah, it's just patches are flying so quickly this weekend, that it's very common to get everything tested and ready to go and then discover ng's been updated while you were busy, and so you have to rebuild and retest again. :)
__rnddim__ IN A WORLD, where hellos come after talking to each other.

colomon: ah, so you're doing different but taking turns pushing and having to pull? that's not so bad, then. :) 17:49
jnthn masak: afaict that's just for the error detection. But akshually we're already screwed by the time we make it into pblock. 17:50
__rnddim__ yes! It took so long last night for this poor old computer to get past that core.pm->core.pir thing, it shut itself down!
masak jnthn: yes, because the EXPR won't let go. 17:51

thus I conclude that the optable parser must have the ability to notice when it shouldn't consume a '<->'.
either by knowing about it directly (probably not) or by realizing that what comes after the '<' isn't a term. 17:54
jnthn masak: iiuc, that's what LTM would give us. 17:55
masak please elaborate.
jnthn <-> is longer than <
masak yes...
I'm with you so far. :P
jnthn But we can't parse <-> as an operator, since it ain't one. 17:56
masak but the EXPR is being parsed by the optable parser, which (IIUC) doesn't even do LTM.
or does it?
jnthn I think it works differntly in STD (and nqp-rx) than it does in PGE.
masak that's entirely possible.
none of the parsers in PGE do LTM. 17:57
17:57 eternaleye joined
masak I just assumed it was only something the recdescent parser would do. 17:57
jnthn My impression is that things aren't quite so divorced in STD and nqp-rx as they are in PGE
masak well, sure, the optable parser always picks the longest operator; that's just common sense.
but in the case of '<->', that's not something the optable parser in a PGE setting would even be aware of. 17:58
since it's not an operator per se.

our multi infix:<after>($a, $b) {

That, in turn, means that Range is pretty broken for anything other than Ints and Nums. 19:17
also negatively affects Rat and Complex math.
probably other stuff too.

that's the first problem.
jnthn masak: Thankfully that's a more general / not too tricky to solve issue. 21:35
masak: just a "name of the punned class not being set" one.
masak I might be totally off, but there's a WHAT in src/builtins/Role.pir that just does '.return (self)'. might that be why it does that?
anyway, that's my guess :)
I have a few more points I want to dump too :) 21:36

masak in general, but strings are not one of the things you can index. 22:13
__rnddim__ so arrays, list, hashes, that sort of thing?
masak or rather, I guess it's up to the .[] method on a type to decide how to treat whatever indices.
__rnddim__: yes... you'd not do .[] on hashes either.
they don't have an ordering in that sense.
__rnddim__ Alright. Off to fix * indices. 22:14

jnthn masak: Yes, me too. ;-) 22:17
Then I (ab)used it to do hash.
masak __rnddim__: well, in the case of @a[0..*], what you have is a call to a .[] method on an array, with the argument being a range (0..*), with the upper bound being a whatever (*).
jnthn: I immediately declared Proxy as my arch-enemy. 22:18
jnthn: I mean, I see what it's for, but I just... I dunno. it's pipes sticking out.

Just wondering about indices. So does 0..5 say [0,5] (in interval notation), 0^..5 say (0,5], and so on?

eternaleye Y'know, it would probably not be too hard to eliminate the downtime from the p6eval bot rebuilding rakudo/ng/what-have-you 23:49
lue compile behind the scenes when it's time, leaving the old one to use, and then quickly switch the old with the new? Doesn't seem that hard... 23:50
eternaleye Just have a bare .git repository of rakudo, and checkout to an external dir and build it. When it updates, checkout to a _new_ external dir, build in that, and then cd to the new dir when it finishes - deleting the old dir behind it
lue: You type faster ;D 23:51
lue I typed less. Don't know about fast...
Then again, I used Mavis Beacon Teaches Typing when I was, what, 10 or 11.
eternaleye The thing is that the bot would have to be aware of it, which might be difficult if the rebuild is a cron job - just deleting the dir under it and renaming in the new one would cause everything to error out 23:52
I still hunt-and-peck. They tried to teach me keyboarding, but it never stuck
