colomon Dunno. The backtrace isn't helpful. Could easily have been line 113 (run 'make realclean') 10:12
pmurias FROGGS: I guess it can be backported to nqp later on, #|, #= seem awesome for generating methods
and a unified doc page for the modules (like metacpan has) seems very important for our fledgling module ecosystem not to end up batshit insane ;) 10:16
with a cute and strange website for every module, like ruby and javascript stuff has 10:17
FROGGS pmurias: it is unlikely that this gets backported to nqp 10:18
pmurias would it be hard? 10:19
FROGGS I think so 10:20

FROGGS also, nqp is meant to be minimalistic
timotimo getting the "no target realclean" happens to me all the time and used to be nonfatal

it can handle a static page just fine, even when we get a few more visitors
if you somehow want to generate static pages from a mojo app, fine by me :-) 12:05

Ensure print/say ops on JVM write UTF-8.

Fixes issues with CORE.setting generation some folks have been seeing.		 13:59
p: 26f36ac | jnthn++ | / (5 files):
Add QAST::NodeList; replace direct QAST::Node use.

This is a prerequisite for moving children out of the QAST::Node base class, which will enable us to save an array allocation and pointer on many node types that don't need children.		 14:01
p: bd41f62 | jnthn++ | / (22 files):
Refactor QAST node structure.

Now only nodes capable of holding children get a slot for them and an array allocated, reducing memory. Also take the time to optimize the new methods so we get away with a lot of the late-bound method calls.

timotimo jnthn: somehow, this thought just popped into my head: 16:28
at some point, someone pointed out how cool it was that we can just put a "proto sub" into the compiler and pass it into the compiled program to have it become part of it 16:29
wouldn't that make the SC that's part of the compiler a dependency of the to-be-compiled program?
i suppose grepping the moarvm bytecode dump of a file for wval calls would give me a map of which SCIDs from which SCs actually end up being referenced 16:30

timotimo i wonder what i'd find 16:30

jnthn: when does such a situation happen?
19:51 dmol1 joined
pmurias jnthn: it has a comment "If we didn't find it anywhere, it musta been explicitly marked as lexical. Take the type from .returns and rewrite to a more dynamic lookup." but I don't understand what that means 19:51
19:52 dmol left, anaeem1 joined
jnthn pmurias: "more dynamic lookup" in this case just means "by name" 19:59
20:06 telex left
pmurias jnthn: but why isn't the lexical declared anywhere? 20:07
jnthn pmurias: Normally it is a post-declaration 20:08
20:08 telex joined
pmurias can we post declare lexicals? 20:10
err, thing other the subs 20:11
* things other then subs
jnthn subs are the typical use case 20:13
In Perl 6 at least

In UNIT, no need for wasteful clone operations.

There's only ever going to be one anyway, since it's in UNIT. Avoids a little work at startup and saves us some allocations, memory, etc.		 22:02

timotimo calling lines() on a file with a gigantic amount of lines ... that will keep all the lines we've gone through so far in memory, right? 22:16
colomon yes 22:17
masak why?
colomon because that's how iterators work at the moment.
unless there have been drastic changes lately I don't know about.
masak bummer :/
that's not... the mental model I have of an iterator (independent of Perl 6). 22:18
jnthn That...wasn't how they were designed to work...
timotimo does subparse really not work with a :pos argument?
22:18 woolfy left
masak an iterator is supposed to be this lightweight cursor-y thing. 22:18
colomon admits he might be wrong, and would love to be surprised in a godo way.
22:18 woolfy joined
colomon …. actually, if you use shift on it it might work? 22:19
timotimo well, lines() uses gather/take
colomon reckons someone is going to have to experiment
timotimo we don't know we're allowed to, right?
unless we get the escape analysis thing going in moarvm %)
colomon is leaving for an outdoor folk festival in about ten minutes.
lue timotimo: IIRC subparse is still anchored to the start, the 'sub' part is that the whole text doesn't have to match to the grammar.
jnthn It's mostly about whether the array/list ends up being bound somewhere...
And so we would have a chance of referring to its values again. 22:20
masak that's what feels weird to me. it definitely *shouldn't* happen in the lines() case. 22:21
jnthn Indeed.
timotimo oh, duh, of course 22:22
lue: thank you.
22:25 colomon left
timotimo yeah, perl6-m at least keeps growing in memory use for lines() 22:27
jnthn ugh
timotimo do we do the same thing for range objects? (well, not if we get the range-for-optimization) 22:28
lue timotimo: S05:4484 22:32
synopsebot Link: perlcabal.org/syn/S05.html#line_4484
lue also, "subparse is anchored to the start and end of the target string" is actually the description of parse() :) 22:33
22:35 spider-mario left
timotimo er 22:35
lue That part of S05 tells me that you can choose where subparse() starts parsing, it's just that the grammar itself has to match from wherever it's told to start. 22:37
timotimo i should seriously put my head deeper into writing application-level perl6, rather than just core/guts %)
