guifa <AlexDaniel timotimo Aearnus>.map(*++) I had just remembered in the docs saying the optimizer had freedom to not do it but wasn’t sure how strong that optimization was. Definitely not worth it then for counting the number of digits in a number :-) 00:14

MasterDuke guifa: .chars wouldn't work? 00:17
00:17 mrsolo left
guifa Negative. -12.3.Str.chars gets you 5 00:17
But I need it to be 3
MasterDuke ah 00:18
then maybe .comb(/\d/).elems ? 00:20

AlexDaniel ugexe: if that starts to throw, then .uniname should too
ugexe: it *feels* like they both do .foos[0]
so in that sense the behavior is consistent and easy to understand 00:45
although it makes me wonder why these shortcuts exist at all :)
like: .ord vs .ords[0], that's quite a bit shorter but are we really designing the language for golfing? :) 00:46
note that the second one explicitly tells you what it means and how it's going to behave in edge cases
00:46 PotatoGim joined
guifa MasterDuke: I went with .comb.map(* ne ‘.’ | ‘-‘).elems, I figure avoiding regex will be a bit faster, but maybe if there’s overhead with junctions I should be wary of and use .map({ $^a ne ‘.’ && $^ ne ‘-‘ }). Although important thing is to get it working first and the junction is clearer to me anyways 00:47
MasterDuke a junction will almost certainly be slower than using && or || 00:48
AlexDaniel ugexe: then there's also .chr which does something completely useless on actual lists
MasterDuke but yeah, a regex is probably also slow 00:49
AlexDaniel and .chrs works fine on single values
00:49 tbrowder joined
AlexDaniel so, why? 00:49
ugexe: ah also, .uniprop goes into the same list with .ord and .uniname 00:50

AlexDaniel I'm fond of throwing things away from the language, so maybe don't listen to me :) 00:53
but I do thing that if somebody proposed `.chr` today we wouldn't add it because we already have .chrs which just works 00:54

06:27 Manifest0 joined 06:34 andrzejku left 06:36 Manifest0 left
discord6 <Tyler (Aearnus)> I have the same question 06:37
Elronnd I found this www.nntp.perl.org/group/perl.perl6...g5203.html (also the reply). Also cro has fancy stuff like http/2 and websockets 06:38
I think I'm gonna go with cro

Elronnd I got a failing test building rakudo in freebsd 06:39

jmerelo Elronnd: you will probably get going faster with Bailador, but in the long run Cro is the best option 06:57
Elronnd: please raise an issue there github.com/perl6/perl6-lwp-simple 06:58
Elronnd: it's working now? jigsaw.w3.org/HTTP/300/Overview.html
Elronnd hum, must have been temporarily down. When I visited it before in my browser it spat out some weird json-formatted error about unimplemented GET or something like that 07:01
alright, I'll do cro then 07:02
jmerelo Elronnd: hum. Might be somethign else. If you've still got that in your terminal, copy/and paste it to an issue.
Elronnd 0nah, wiped that screen 07:03
is probably fine though
I'll run a make test and see what happens
jmerelo Elronnd: thanks!
Elronnd yep, tests for lwp simple pass now 07:08
(maybe shouldn't depend on a third-party website for that test, though?)
07:11 sivoais_ joined, sivoais left
Elronnd hmmm, when I run the 'cro' command, it just hangs forever, no matter what I give it 07:13
xq definitely should not depend on something as fragile as network for tests 07:15
would be more reliable to make a temporary http server listen on 127.0.0.1 and test using that 07:16
Elronnd well maybe, but then you have to test the server too
so it's unclear if what's being tested is client or server
xq on a bright side this setup theoretically should fail in a reproducible way 07:17

Got it right this time

Curried roles are simply roles that have been provided with a parameter, but before they have been fully instantiated by punning or being mixed in a class. [Synopse](design.perl6.org/S14.html), for once, was useful.

Elronnd Is cro awesome enough to be exposed directly to the open internet, or should I still reverse-proxy it behind nginx? 08:13
08:16 sauvin left 08:20 andrzejku joined
jmerelo Elronnd: there are many sites in production, including Edument's 08:23
Elronnd but do they run nginx in front of it, or do they let cro handle everything itself? 08:28
08:28 sauvin joined
jmerelo Elronnd: not sure. I think not, but you can ask sena_kun or jnthn when they are around. 08:28
Elronnd I guess the question is, does the increased speed from the static file-serving outweight the increased latency added by the second http connection you need for reverse proxy? 08:29
ok

guifa Is there a cleaner way to conditionally pass a named parameter based on its definedness? (I know theoretically I could use a capture slip, but then I lose some of the self-docmenting that goes from explicitly mentioning it) 15:23
Right now I’m using foo( |(:$bar if $bar) ) but it just feels… ugly 15:24
If I pass directly, the second method gets an Any type and that prevents the default value from being loaded 15:27

timotimo DrForr: did you know about "<comment> +"? 22:28
DrForr: also, the paragraph near the end about "the csv test suites" sounds like you're referring to tux's test-t, but that uses stuff other than regexes to become fast 22:31
22:32 zacts joined 22:34 TBC_z87 joined 22:35 MasterDuke left
guifa So say I have a grammar Foo. It can get instantiated with special settings and has associated actions that are basically obligatory for it to be usefull. What’s the best way to use that instantiated grammar in another grammar? Or is the only way to make the new grammar a subclass of Foo? 22:39
guifa thinks it would be awesome to actually be able to request a reusable regex/grammar that detects numbers — based on locale — even when percentages/exponential/etc, and then can provide the value 22:45
jnthn guifa: Dunno if it helps, but it's possible to put tokens/rules/regexes in a role also 22:48
guifa: Which means you can make composable pieces that are then put together 22:49
timotimo if the actions are so inextricably linked to the grammar itself, it may not be the worst idea to actually put them inside the tokens/rules/regexes 22:51
guifa Ah! That would be much more agreeable than a grammar (and make more sense, “grammar DocumentParser does LocalizedNumberParser” sounds much better than “grammar DP is LNP”) 22:52
With the NumberFormatter grammar already made it shouldn’t be too hard to make a new one that does lenient parsing 22:54
timotimo or even "also does ParseLocalizedNumbers" 23:00
"also does That-Thing-With-The-Numbers" 23:05
