ab5tract Interesting... I've got things mostly working with flip flop but prefix:sym<^> seems to match `$a ff^ $b` (`$a ff $b` and `$a ^ff $b`) work fine 11:25
it tries to create a ^$b range object in the ($a ff^ $b) case 11:26
lizmat hmmm... maybe the precedence of ff is wrong? 11:27
or of prefix:<^> ? 11:28
ab5tract it should be auto-getting stuff from OperatorProperties, right?
lizmat yes, but maybe I copied it incorrectly into OperatorProperties: there were several sources of information in that respect, and not all of them had the same info :-( 11:29
I mean, if it ASTs into a RakuAST::Infix, yes
ab5tract yeah, it does
11:29 camelia joined
lizmat ff should have precedence j= 11:30
ab5tract what's the best way to check the precedence? 11:31
lizmat looks like prefix:<^> has precedence v= which is higher... which feels... hmmm
ab5tract yeah, not sure how the parser is supposed to interpret that one
lizmat checked with legacy grammar, looks like OperatorProperties is in sync with that 11:34
ab5tract shouldin't it be a case of LTM? 11:35
lizmat aaah... I think I now what I borked 11:36
*know 11:37
testing.... 11:39
Geth rakudo/main: cd32d6a3fd | (Elizabeth Mattijsen)++ | src/Raku/Grammar.nqp

lizmat pretty sure that will fix it

ab5tract grrr... so close to a finalized flip flop 14:55
the only problem comes from `/F/ ff *` 14:56
it's definitely a tricky one to solve, all I have to go on is: `No exception handler located for catch` 14:57

nemokosch how to interpret these values? what do they mean to someone who looks at this chat? 15:11
MasterDuke tux.nl/Talks/CSV6/speed4.html 15:20
there are some other speed<N>.html pages also 15:21
nemokosch I get this part but why does this need to be sent into the chat periodically? 15:25
wouldn't it make more sense to at least only send it on certain noticeable events?

lizmat nemokosch: in the past, test-t (as we call it) as been a very useful canary for performance regressions.. so it's good to see it done frequently 16:06
nemokosch It has no meaning out of context. Do you know by heart which test should run under what time? 16:13
I think it's as if geth was set up to post the number of issues in Raku-related github repositories 16:14
MasterDuke but it has ~8 years of context. i couldn't tell you all the names and their usual times out of the blue, but when i look at that list those numbers seem normal 16:21
the context is all the years of posting them on irc and the discussions about them. though they are much less frequent than they used to be, i assume mostly because there aren't very many large changes anymore 16:23
lizmat irclogs.raku.org/perl6-dev/search....iases=True 16:30
nemokosch the same argument could be made for Geth and Raku-related issues, it's kinda self-justificatory 16:35
I'd say the difference is exactly that there are no discussions or anything, there is nothing to be talked about, and then is it really mandatory to dump it into IRC? 16:39

ab5tract feels like some ultimate YAGNI to me, but I'm sure it makes someone out there very happy 18:03
18:03 nebuchad` joined
ab5tract what's the use case of this thing? 18:09
nemokosch extracting out a part of a text stream based on some delimiting patterns 18:10
... or so I heard 18:11
I think it's too "clever" to be actually useful
lizmat it's something engrained in sed users apparently 18:20
[Coke] I need it maybe once every 2-3 years, it's nifty but not something I rely on

leont Crap, if I had finished a blogpost of mine, I could have explained it easily, but I haven't. 19:04
The flip flip operator is absolutely essential when using the language as an awk replacement. And almost entirely useless for any other use-case 19:05
That means in Perl it's absolutely essential, but Raku much less so. Mainly because Raku's improvement tend to be on the other side: being a better language at scale. 19:07
Perl is the best awk that was ever written, Raku never was about being a better awk than perl, but about being a better language at scale. IMO. 19:08
ab5tract well, it's working in RakuAST now :) 19:41
