| rcmlz | Thank you. „>>“ is something I need to use more often. SmokeMachine: interesting solution. I do not understand yet, why the order is preserved … | 05:10 | |
| jubilatious1_98524 | antipairs makes each line into a key/value with line-number as value. The final sort reconstructs the input order (head insures that only the first value per key is used for sorting). Clever. | 06:55 | |
| Hi, I don't uunderstand what "line 20" refers to. Could you explain? Thx. | 07:05 | ||
| FYI, I tried to write awk-like Raku, so people reading the accepted answer (15 Upvotes) would see parallels. Cheers. stackoverflow.com/a/77964930/7270649 | |||

| rcmlz | With line 20 I was refering to the glot.io link. My final version, taking also memory into account is # read all lines from standard input - we need it twice, hence we store it in an array my @numbers = $*IN.lines; # find numbers that appear only once my %singletons = @numbers.Bag.grep(*.value == 1); # print the single-occurrence numbers in their original order @numbers.grep( -> $n { %singletons{ $n }:exists } | 10:27 | |

| _elcaro_ | You could also do that this way perl @numbers.Bag.grep(*.value == 1).Hash{@numbers}:k I always try to remember when doing something like @xs.map({ %h{$_} }) that I can often just do %h{@xs} | 14:22 | |

| antononcube | For all of the NIX-addicts -- is this something easily (re-)doable in Raku: quesma.com/blog/60s-linux-analysis-nix-llms/ | 15:05 | |

| librasteve | @myrlynx depending on your platform, you may need some developer libraries installed for the SHA1 to work... | 17:16 | |

| myrlynx | I think I got it working from installing from source | 17:22 | |

| antononcube | I have to always do that on macOS. | 18:24 | |
| librasteve | recently I have tested a clean new user on macos against the proposed install methods listing on the new raku.org site - so homebrew and rakubrew have been successful for me - also @arkuiat asked me to add MacPorts today (and I trust that he would only do that if it works reasonably well with a reasonably recent version installed) | 19:43 | |
| please do highlight to me any issues with any install method listed on the new raku.org and I will try to adjust the defaults | |||
