| disbot | <rcmlz> I found use v6.e.PREVIEW; say "élève".nomark; # eleve on raku-advent.blog/2024/12/25/day-25...24-review/ so there is even more options to tackle this sorting problem in the future. | 08:37 | |
| lizmat | yeah, the nomark in String::Utils was backported from that | 08:39 | |
| disbot | <simon_sibl> is there a better way to stop a react block when some whenever block are done ? termbin.com/ysa5, not sure this is the most Raku way | 09:03 | |

| disbot8 | <jubilatious1_98524> @simon_sibl Looks good! That's more graceful that what I've tried (tailing a logfile): unix.stackexchange.com/a/721958/227738 | 11:40 | |
| <simon_sibl> now that I saw this, I wonder if its possible to pass arguments to raku one-liner without Raku trying to open them as file to read | 12:01 | ||
| <jubilatious1_98524> Sure, use the %*ENV trick: unix.stackexchange.com/a/611077/227738 | 12:12 | ||
| <jubilatious1_98524> ( ...got that from Larry Wall!) | |||
| <jubilatious1_98524> More generally, there are many other examples where I've used it: unix.stackexchange.com/search?q=us...38+%25*ENV | 12:13 | ||
| <simon_sibl> oh I used another trick that I just found | 12:14 | ||
| <simon_sibl> tail -F logs | raku -ne 'my @a; BEGIN {@a=@*ARGS;@*ARGS=();}; say $_.split(/";"|"="/,:skip-empty)[1..*].hash{@a}:kv' ares_recv | |||
| <simon_sibl> not amazing but well | 12:15 | ||
| <simon_sibl> actually using :p instead of :kv here looks better | 12:19 | ||
| <jubilatious1_98524> Are you calling @*ARGS twice? I've never seen that. Generally if you want to take a value/file pair you would use my $value = @*ARGS[0]; my @array = @*ARGS[1].IO.lines; | |||
| <simon_sibl> and does what the guy seem to want | |||
| <simon_sibl> oh I first copy @*ARGS and then I empty it otherwise it will try to open them as file | |||
| <jubilatious1_98524> What's in ares_recv ? | 12:20 | ||
| lizmat | m: my @a = <a b c d e>; my @b := @a.splice; dd :@b, :@a # fast way of copying & emptying out an array | 12:21 | |
| camelia | :a([]) :b(["a", "b", "c", "d", "e"]) |
||
| disbot8 | <simon_sibl> oooh nice ! | ||
| <simon_sibl> so the one liner: tail -F logs | raku -ne 'my @a; BEGIN {@a=@*ARGS.splice}; say $_.split(/";"|"="/,:skip-empty)[1..*].hash{@a}:p' "$@" | 12:22 | ||
| <simon_sibl> the "$@" is because I added it in a script | |||
| lizmat | this actually just moves the internal list of @a to @b, and reinitializes the internal list in @a | ||
| disbot8 | <simon_sibl> ares_recv is one of the key in the log file, you can give multiple key as argument and it shows those | ||
| <simon_sibl> thats exactly what I needed, thanks ! | 12:23 | ||

| disbot8 | <simon_sibl> I just a person on Quora asking why Raku is faster than Python, but usually when I do benchmark Raku is slower, like I did a test between my Raku code and my colleague Python code for the scheduler and the Python one ran 10x faster (I’ll send a link to both code) | 14:12 | |
| <simon_sibl> raku: termbin.com/znm3, python: termbin.com/oic2 | 14:13 | ||
| <simon_sibl> I am pretty sure they're not completely equivalent but they do the same thing | |||
| <simon_sibl> raku: 255.78 millis, python: 18.25 millis | 14:14 | ||
| lizmat | well, if you're doing that type of benchmark, Raku will always lose, as you should currently expect about 100 ms at least for Raku's startup | 14:20 | |
| disbot8 | <simon_sibl> Removing 100ms for startup, it’s still 130ms behind | 14:42 | |
| lizmat | true, but how does it compare with a workload of several seconds? | 14:43 | |
| on Intel, MoarVM has a JiT, and that takes a bit of warming up | 14:44 | ||
| disbot8 | <simon_sibl> By intel you mean x86_64 or intel cpu only (my laptop has an AMD) | 15:02 | |
| <simon_sibl> I will try later with more input data | |||
