xinming docs.perl6.org/routine/listen <--- In this page, there is an example which is $tap = do whenever $listener -> $con { ... } Anyone here would clarify this for me? Where did the tap returned from? 10:18
Or, $tap = do whenever $listener -> $con { ... } is kind of syntax we should remember.

Top five countries: US, UK, Germany, France and, surprisingly, Australia. Then Switzerland, Spain, Canada, India and Netherlands. 10:33
Most read articles by me (no wonder, the one that opened and closed), tbrowder, altai-man, tyil, scimon. 10:34

Meanwhile, the call for contributors to 2020's advent calendar is officially open github.com/Raku/advent/blob/master...authors.md This year there are no preassigned slots, and we'll admit as many authors as request it. But articles will need to be ready by Dec 1st, and will be scheduled when ready. 10:38

should I file a bug report, I don't think this should happen
chloekek You can do that in C++ too but the precedence is different. :) 13:20

sarna shouldn't ?? !! have the lowest precedence? so I don't have to wrap the stuff inside in () 13:21

camelia WARNINGS for <tmp>:
Useless use of $foo in sink context (line 1)

chloekek That would make sense.
moritz precedence misuse, not a bug
chloekek ??!! seems to have rather high precedence: docs.raku.org/language/operators
moritz and that's because you often use them as the RHS of an assignment 13:22
chloekek But only one level higher than assignment.
moritz $a = $b ?? $c !! $d
for that, it needs to be tighter than assignment
sarna oh.. yeah I'll have to remember this then 13:23
moritz and since += inherits its prec from = (and not +), it causes confusion when you use += inside ?? !!
sarna thanks for the help :)
yeah

You can find the list of versions on github.com/rakudo/rakudo/releases

Within-page links will not work when that fragment is included somewhere else. Closes #3130

jmerelo releasable6: status 17:40
releasable6 jmerelo, Next release will happen when it's ready. There are no known blockers. 0 out of 323 commits logged
jmerelo, Details: gist.github.com/30bb3b8197f4b2250f...4297ba8a85
sena_kun jmerelo: release will happen mid-January, I hope 17:41
jmerelo sena_kun: great :-) 17:42
17:43 veesh joined
Poohmaan just curious, is all this possible in other dynamic languages 17:45
sena_kun sure, why not
maybe in different syntactic ways, of course 17:46
Poohmaan I meant usage of functions and user defined routines directly as arguments for sort
functional first languages would support them 17:47
Grinnz it was originally a feature of perl, yes
perl hasn't quite got it looking as pretty as raku does yet
Poohmaan because I was able to read the line from the file - parse it as Json in the function and then use that as an argument for the sort - found that to be pretty cool 17:50
thanks again all
stoned75 hi. where can I find an usage example of traits leading_docs or trailing_docs ? 17:51
jmerelo stoned75: hi. Great work, BTW, in the documentation 17:52
tobs `sub f { 42 }; say &f` <- I tripped over this more than once when switching between Raku and Perl...
stoned75 jmerelo: you're welcome !
jmerelo stoned75: I'll tell you all my dirty tricks as a documentor
stoned75 nice ! :)
jmerelo stoned75: first, you look in roast. If it's spec, there's a high likelihood there's some example there. 17:53
17:53 veesh left
jmerelo stoned75: second, look in github at large. Just use the Github search engine to look for examples "in the wild". Even if something has not been documented _or_ specced, brave souls sometimes manage to use it in the wild 17:53
17:54 veesh joined
jmerelo stoned75: stoned75 that might turn some code in Rakudo, usually. Which sometimes is hard to follow, even more so if it includes NQP code. The commit that changed the code might help 17:54
stoned75: so use git blame to look for the particular commit, which might take you to maybe an issue, or at least some context or additional documentation. 17:55
stoned75: that might fail, however. So just start and program an example in the way you think that would work. It might not work, but error messages might put you in the right direction. 17:56
stoned75 ok great! many thanks for the hints !
jmerelo stoned75: or you may github-search the error message and get to the code.
in this case, I couldn't say, really... 17:57
stoned75: but please raise an issue anyway, or assign that issue to yourself if it's created.
stoned75 ok understood 17:58
jmerelo stoned75: there's this issue github.com/Raku/doc/issues/2825 which's got lots of stuff. Just say in a comment you're working on those. 17:59

johnjohn101 ok dumb question 18:06
how to i run a raku script? just need simple helloworld to get started 18:07
Geth_ doc: 88a0af3b83 | (JJ Merelo)++ | doc/Type/Map.pod6
Reduces line length.
veesh if you have it installed, there's a REPL where you can do those fun things
it meaning raku, it comes with the REPL 18:08
otherwise you could use a shebang line `#!/usr/bin/env raku`
or manually call the raku program on your script
johnjohn101 i just installed using the ppa repo on ubuntu
i run raku and it can't find the program 18:09
sudo apt-get install rakudo-pkg is what i ran 18:10
chloekek What does perl6 --version say? 18:12
johnjohn101 not foud
ok it's in /opt let me see if in path 18:13
Grinnz that doesn't seem right for something from apt 18:14
chloekek Why would a .deb package install something to /opt
johnjohn101 that is what surprised me
veesh you use rakudo-pkg? 18:15
it doesn't add raku to your path for you
johnjohn101 what ever was in these instructions
github.com/nxadm/rakudo-pkg#os-repositories 18:16
veesh read a little bit lower, you needa set the path
Grinnz ahh, not official repo, that makes sense
johnjohn101 ok sorry i was assuming 18:18
stoned75 jmerelo: thanks again. and FIY I tracked down leading_docs to this commit github.com/rakudo/rakudo/commit/88...0e04999754 18:20
and similarlyfor trailing_docs
andso its related to roast/S26-documentation/block-{leading,trailing}.t 18:21
xinming Where can I check the logic for do whenever please? 18:24
jmerelo stoned75: great job! That one is only for Attributes, however. There are three versions of them. 18:25
xinming: is it not well covered in the documentation?
xinming I just now googled a lot, find nothing, and no any useful info on docs.raku.org either, So, this makes me quite curious about behavior of 'do whenever ... { }', As far as I tried, It always returns a Tap.new 18:26
jmerelo: Nope.
18:26 cqd left
johnjohn101 ok where is panda? 18:26
xinming jmerelo: there is documentation about whenever, but nothing about `do whenever`
18:26 cqd joined
jmerelo johnjohn101: deprecated 18:26
xinming: can you please raise an issue?
johnjohn101 how can i install dbiish?
xinming The only reference is here docs.perl6.org/routine/listen
jmerelo johnjohn101: zef install DBIish
johnjohn101 ok thanks 18:27
xinming jmerelo: Ok.
18:27 cqd left
johnjohn101 sorry complete noob here. 18:27
jmerelo johnjohn101: no problem, just ask
johnjohn101 is that global or per project?
xinming johnjohn101: You'll love it here, all people here are newbie friendly. :-)
jmerelo johnjohn101: panda was deprecated some time ago, but it's still in some documentation...
johnjohn101: zef is the only module and dependency management app now 18:28
xinming jmerelo: where should I create the ticket?
18:29 cqd joined, johnjohn101 left
veesh why does raku create a .precomp in the directory that it was run in, and not in some fixed location in your home directory? 18:30
my system is littered with lib/.precomps everywhere
xinming jmerelo: I know it's github, I just don't know the repo for docs. :-) 18:31
18:31 johnjohn101 joined
xinming veesh: Because they are pre-compiled files for faster loading. 18:31
veesh no, but wouldn't you want them in one well-know place on the system
stoned75 jmerelo: roast covers all variations. and as the code involved in their implemention hints it the leading,trailing}_docs really seem to be internals one 18:32
and indirectly they are documented in language/pod#Declarator_blocks ;-)
xinming veesh: Well, You asked something I wanted to know, but low priority to me. :-)
18:33 chloekek left
stoned75 jmerelo: and I found the answer to my original question: "and usage example of traits trailing_docs" :-) 18:40
it is in rakudo/src/Perl6/Pod.nqp:document() ;-) 18:41
