samcv i think i found a serious bug in ucd2c.pl. investigating 06:22
basically causes it to not store any properties on any codepoint that is not in UnicodeData.txt 06:23
so any of the not mentioned in that file just get ignored

samcv well i guess it's not that serious for most people. but. a serious issue in the script. most people don't rely on property values of reserved codepoints 07:21
though it could be more important if someone is using an older perl6 and if the property values are more right based on expected usage or something 07:22

timotimo the exception ops that get jitted still all put a validation in front, i.e. "is the object concrete and is the type right?"; with a proper implementation of these ops it could be a tiny bit faster, but definitely not much 12:38
not enough to get us below 3.0 anyway 12:39

timotimo which is fine, i expect that's for iterating a loop
dogbert17 split definitive rings a bell 13:01
*definitively
timotimo that looks to be the kv loop inside split where it goes through the needles 13:02
dogbert17 it's already nqp code it seems 13:03
timotimo right 13:04
i'm going to try with a simple iteration and a variable $index that i increment myself 13:05

dogbert17 but does it pass a spectest ? 13:10

dogbert17 this is exciting
timotimo i find it rather mean to snatch the "going from above to below 3s" thing from liz and jnthn who put considerably more effort into this than i just did 13:14
dogbert17 should jnthn or lizmat take a look at your change or are you confident that it is correct? 13:16
timotimo the spec tests shall prove them correct 13:17
the change is basically trivial

wander DrForr: somewhat lack of generality, I'd like pod2html only to generate html body, maybe provide class attr for custom css. it was well designed, but modify for some particular purpose(like fit sth about generate doc site), that's OK. but as where you arrive, someone has to(?) *refactor*(not simply modify) it to adjust his own use 15:04
gather meta message and make the toc are useful, we can export subs(return $toc, @meta, @x-tags) for that 15:05
DrForr Isn't it terribly convenient then that what I'm working on is Pod::To::BlogspotHTML which has just a bare <body/> element - Blogspot does the heavy HTML lifting for you.
wander nowadays web devs use html template generally, maybe generate the whole web page is not that admired. after all, it can provide an adverb to generate a full html using default template. 15:11
render($=pod, :whole) 15:12
our doc site relies heavily on current p2h, anyway

camelia Hash %h = {"24" => 42}
{"24" => 42}
lizmat binding to a clone of a Hash should disentangle with the original hash, one would expect ?
masak I was gonna answer "yes", but given that Pairs are first-class, I actually don't know... 22:30
perlpilot lizmat: feels wrong to me too. 22:31
masak would be interesting to know if any spectests break under the other behavior 22:32
AlexDaniel squashable6: status 22:33
squashable6 AlexDaniel, 🍕🍕 SQUASHathon is in progress! The end of the event in 1 day and ≈13 hours. See github.com/rakudo/rakudo/wiki/Mont...Squash-Day
AlexDaniel, Log and stats: gist.github.com/598e58419879ad2703...e855393d3e
lizmat masak: there are no Pairs at that point in the code, just an nqp::hash underneath? Or am I missing something ? 22:34
masak lizmat: no, probably I am 22:35
lizmat: but it just felt less clear-cut with Pairs (possibly) in the picture
lizmat now, if it were an object hash, you'd have a point :-) 22:36
masak like, you could conceivably clone just the Hash but none of the Pairs
lizmat I think I understand what's happening: the hash contains containers, which *aren't* cloned 22:38
so you wind up with a new hash with the same old containers
masak does the same apply for arrays?
lizmat possibly, haven't checked 22:50
yeah, it's a container not being cloned issue: observe: 22:52
my %h = a => 666; my %i := %h.clone; %i<a> = 42; dd %h, %i
m: my %h = a => 666; my %i := %h.clone; %i<a> = 42; dd %h, %i
camelia Hash %h = {:a(42)}
{:a(42)}
lizmat m: my %h = a => 666; my %i := %h.clone; %i<a> := 42; dd %h, %i
camelia Hash %h = {:a(666)}
{:a(42)}
lizmat the second case we bind to the key, thereby removing the container in the cloned hash, and thus not affecting the original hash 22:53
masak: arrays don't have that issue because: " multi method clone(Array:D:) { [self] }" 22:55
which is pretty yuck from a performance point of view
so I guess it boils down to: what *are* the intended semantics of .clone ? 22:57
m: my Int @a = ^5; my @b := @a.clone; @b[0] = "foo"; dd @b # another consequence of Array.clone's implementation 22:59
camelia ["foo", 1, 2, 3, 4]
lizmat m: my Int @a = ^5; my @b := @a.Mu::clone; @b[0] = "foo"; dd @b # appears more correct 23:00
camelia Type check failed in assignment to @a; expected Int but got Str ("foo")
in block <unit> at <tmp> line 1
timotimo m: my @foo = 1, 2, 3; @foo[1] = |(1, 2, 3); say @foo.perl; say @foo.clone.perl; 23:10
camelia [1, slip(1, 2, 3), 3]
[1, slip(1, 2, 3), 3]
timotimo oh, ok
scalar containers, /me remembers
m: my @foo = 1, 2, 3; @foo[1] := |(1, 2, 3); say @foo.perl; say @foo.clone.perl;
camelia [1, slip(1, 2, 3), 3]
[1, slip(1, 2, 3), 3]
timotimo it even works if i replace that scalar container? 23:11
lizmat timotimo: that feels like another issue, namely postcircumfix [] not handling Slips correctly ? 23:13
m: my @foo = 1, 2, 3; @foo[1] := |(1, 2, 3); say @foo.perl; say [@foo].perl 23:14
camelia [1, slip(1, 2, 3), 3]
[1, slip(1, 2, 3), 3]
lizmat looks like circumfix [] isn't handling slips correctly ? 23:15
or is this intended behaviour ?
timotimo good question
i would have expected my code to mess up and give something different after the clone 23:16
lizmat anyways, the disentanglement that moritz did in response to masak's RT #127704 , seems to introduce inconsistencies
synopsebot RT#127704 [resolved]: rt.perl.org/Ticket/Display.html?id=127704 [BUG] Hash.clone differs from hash assignment; the hash and its clone are spookily entangled
lizmat oddly enough, removing github.com/rakudo/rakudo/blob/mast...ray.pm#L50 doesn't seem to break any spectests 23:20
I think the problem really comes from .clone acting differently because of implementation detaiuls 23:21
*details
the fact that Mu.clone clones all private attributes, and let's you twiddle public attributes 23:22
is fine for non-core objects, where the developer has control over what the attributes are and whether they're private or not
for core objects, this is different, because they're really implementation details, or am I wrong? 23:23
