Yeuph is there a way to set an interval for a range? 01:28
I think I remember it
like 2..4..16 01:29
so I get 2, 4, 6, 8, 10, etc
shmup 2, 4, ..., 16 maybe. i forget im stlil new 01:33
Yeuph yeah its something like that
I don't need to do it right now but it's just been nagging at me lol 01:34
shmup [5] > 2,4...16
(2 4 6 8 10 12 14 16)
m: 2,4...10 01:35
camelia Potential difficulties:
Useless use of ... in sink context
at <tmp>:1
------> 32,4...⏏510
guifa_ make sure if doing the interval with a range that your final value is actually in the series 01:45
m: my @a = 2, 4, ... 11; say @a[10]
camelia Potential difficulties:
Comma found before apparent sequence operator; please remove comma (or put parens around the ... call, or use 'fail' instead of ...)
at <tmp>:1
------> my @a = 2, 4,⏏ ... 11; say @a[10]
11
in bl…
guifa_ m: my @a = 2, 4 ... 11; say @a[10] 01:46
camelia (Any)
guifa_ Errr we used to stop when smartmatching it. I guess lizmat did fix that to DWIM

el gatito (** advocate) 2, * + 4 ... * >= 16 02:59
2 is the initial value, * + 4 is the update callable, * >= 16 is the stop condition 03:00
also i noticed i can create factorial using ... it will just look ugly 03:12

habere-et-disper The latest rakudo star 2023.02 fails to build for me with: 09:38
Experimental "my" subs not enabled at /private/var/folders/rb/43pg1z6j64dfr5w50fz8pns80000gp/T/tmp.SG33WUH2/3rdparty/nqp-configure/lib/NQP/Config.pm line 1519.

my sub on_stdout {

    $last_out_at = time;
}
Any workarounds ?
Nahita hi habere-et-disper, what's the version of Perl you use? 09:42
habere-et-disper v5.18.2 09:43
Too old ?
Nahita it seems so 09:44
perldoc.perl.org/5.28.2/feature#Th...s'-feature
from 5.26+, "my" subs are enabled by default
habere-et-disper Retrying compile with newer perl...
Nahita but for 5.18+ to 5.26, one needs to opt for it explicitly
habere-et-disper Thanks!
Nahita np hope it works 09:45
habere-et-disper It takes ~30min to compile... I'll report back.
Nahita ooh, okay
habere-et-disper Okay -- so that compiled okay. Whew! :) 10:29
We have a few modules that failed to install. Should I try zef install them? They are:
  rakudoc
  Log
  Log-Colored
  Terminal::LineEditor 10:30
  IO-Path-XDG
  Config
  Config-Parser-toml
  Config-Parser-yaml
  Config-Parser-json
  DBIish
  Perl6-PathTools
  OpenSSL
  IO-Socket-SSL
  PSGI
  HTTP-Easy
  Temp-Path
During compile these things appeared missing: 10:31
Config::Parser
Text::MiscUtils::Layout
IO::Socket::SSL
Digest::SHA
HTTP::Easy::PSGI
