move Str.subst proto to be next to its methods

No functional changes. The proto for Str.subst seems to be hundreds of lines away from Str.subst methods, tucked next to Str.substr-*
Fix by moving the proto in the source code.		 00:18

TimToady heh, I'm told that six or eight generations back, my last name used to be spelled "Walde" 01:42
MasterDuke TimToady: in a quick attempt to get rid of @*comp_line_directives, i tried turning it into an attribute (with an accessor method) in src/HLL/World.nqp and then calling $*W.comp_line_directives() in src/HLL/Compiler.nqp 01:45
but it compains, `Cannot find method 'comp_line_directives' on object of type NQPMu`
*complains 01:46
TimToady it might be set up before there even is a World 01:53
I wouldn't sweat it too much; it might end up riding around in the new braid object anyway 01:54

Add Braid type, move actions to braid object

Cursors now maintain a braid delegate to hold aspects of the current language braid that are outside the scope of the current set of cursor methods, but nonetheless contribute to the notion of "current language" in the current lexical scope. We will be migrating various dynamic variables into the braid over time, such as %*LANG, %*PRAGMAS, and $*PACKAGE.		 07:45
rakudo/braids: f526c7d72d | TimToady++ | 2 files
Start using new braid abstractions from nqp

We will gradually be weaning rakudo off of direct manipulation of cursors and dynvars so that we can abstract the various "current language" concepts into the Braid object that hangs off the current cursor.

brokenchicken FWIW, I've not restarted SourceBaby/Undercover for a couple of months (I think?) and they were in just 600-700MB of used RAM. Whatever's leaking in buggable has gotta be applying a regex to a huge chunk of text (entire Travis build log). 16:05
Don't think I'll have the time to golf it any time soon, but yey for other bots seemingly not leaking :) 16:06
jnthn brokenchicken: What Rakudo version? 16:07
A MoarVM commit almost right after the January release fixed a major release
brokenchicken SourceBaby/Undercover were running on some 2016.10-* commit. The box with buggable has 2017.01-144-gf2894d3 installed, but I'm pretty sure the last time I saw it leak it was a slightly earlier commit 16:08
like maybe a week earlier
jnthn OK
Anything using Proc::Async will have got a good bit less leaky
brokenchicken I think it's something with regexes... 16:09
And well, should be easy enough to find out what it is. I just need to find time to do it. 16:10
wooo found a fix for 130688 17:21
And seems $caller_dollar_slash / $SET_DOLLAR_SLASH in Str!APPLY-MATCHES are useless 17:22
brokenchicken always gets suspicious when finding "useless" chunks of code
The method's called only from .subst/.subst-mutate (and Actions for s/// / S///) but in all those cases dollar slash is already set by Str.match call, so there's no point in asking APPLY-MATCHES to set anything. In fact, it's what causing the 130688 bug 17:24
And I don't get why does s/// S/// call .match / !APPLY-MATCHES instead of just calling .subst/.subst-mutate :\ 17:49
:S and apparently s/// | S/// code creates $global_result just to re-bind $result to it, just before sticking it into $/ :/ 18:14
Though I broke something by removing this stuff, so I guess I'm wrong :} 18:18

brokenchicken It gives you all the matching candidates in narrowest -> widest order
And IIRC for methods you need to include the invocant in the capture you give it
Hm. Weird. I stuck this debug statement into actions quote:sym<s>: QAST::Op.new(:op<say>, QAST::Op.new( :op<callmethod>, :name<gist>, QAST::Var.new( :name('$/'), :scope('lexical') ) )) 18:28
[Coke] weird. it's finding hte method I thought it was, but then my { die "AAA" } in that sub is never invoked.
brokenchicken And it prints TWICE for each of invocation of s/// :S
[Coke] DOH. installed vs. local.
yay, my patch worked. 18:29
brokenchicken hm, but sticking QAST::Op.new(:op<say>, QAST::SVal.new(:value<meows>)), right before that debug statement prints 'meows' just once :S 18:37
brokenchicken doesn't get this...

brokenchicken vov
And I changed it to QAST::Op.new( :op<callmethod>, :name<gist>, QAST::Var.new( :name('$/'), :scope('lexical') ) ), and now it prints it just once... waaaaaaat 18:39
oh, I had code as `say s///` oops :P 18:40
-_- don't get it. With my patch $_ = "a b c"; .subst-mutate: :g, / (\w) /, -> $/ { "$0$0" }; replaces with "aa bb cc" but s:g/ (\w) / $0$0/; replaces with "aa aa aa"; my debug print of APPLY-MATCHES shows both versions give the same args and $/ ends up being the same :| 19:45
timotimo maybe the s:g/ / / form tries to go with the lexical $/ outside of the s/// call? 19:57
brokenchicken APPLY-MATCHES doesn't do anything with it and takes matches via an arg; I dumped it from inside APPLY-MATCHES and it's the same for both versions 19:59
brokenchicken goes to compare ASTs 20:00
timotimo unfortunately i don't know how that part of rakudo plays 20:04
brokenchicken I saw the light. 20:29
And I was right... three hours ago... "* │ brokenchicken always gets suspicious when finding "useless" chunks of code"
The s/// S/// forms give matches lazily and rely on $/ being swapped for each substitution, while .subst-mutate expects args to the codeblock 20:30
At least now I have a much better knowledge of thist stuff :) 20:31
Well, if the stresstest ends up clean I will have fixed 130688 and may even have time to commit it before I have to relocate :) 20:41

brokenchicken That now gives: (|foo bar baz|,|foo bar baz|,(|foo bar baz|))
But I'd argue the new version is correct. The block doesn't receive it's own $/; if you want to use $/ inside, block needs to be -> $/ { } 20:47
Well, s/new version/; The only reason it ends up as anything is matches are done before replacements.

lizmat .tell jnthn there's a bunch of methods in core (e.g. .eager) that have a proto with (|), but never take any arguments. Making the proto have () appears to make it 4% faster. Do you see any downsides to this? 23:36

jnthn lizmat: But, for eager at least, that seems overwhelmingly unlikely :)
lizmat but wouldn't somebody just need to add their own proto if they wanted an eager with params ?
jnthn They can, but of course they'd also need to handle the zero-arg case 23:44
But it's such a hypothetical thing to want to do anyway, for eager... :)
So, for that case I think no problem to change it

jnthn OK, probably worth considering each of them :) 23:45
lizmat pairup minpairs maxpairs Array List flat
jnthn Array and List are coercers
lizmat hash Hash Map
jnthn flat is like eager
Those are all coercers
So only pairup minpairs maxpairs warrant any particular thought 23:46
