timotimo | what i like to do is have a channel where i send a specific number of permits and when i want to do something that consumes a resource i receive from the channel and when that part of code is done it sends on the channel | 00:02 | |
actually, it might be better to "await" the channel, because that can suspend the task back to the thread pool i assume | 00:03 | ||
guifa | Hmm, I'll look into trying that. Although ultimately all this is just trying out different features. As long as my project runs, multi or single threaded, my dissertation advisor will be happy haha | 00:05 | |

thowe | Hi, Perl6. Tell me things that will make me happy. | 00:44 | |
MasterDuke | Herby_: fwiw, rakudo doesn't lift the @target_array.elems out of the loop, so it's being called for every iteration. elems is pretty fast, so it frequently doesn't matter, but good to know | ||
Herby_ | thowe: I just brute-forced hello world | ||
MasterDuke: I didn't know that. Thanks! | |||
thowe | OK, cool. I didn't know Hello World required much in the way of force, but you do you. | 00:45 | |

Herby_ | MasterDuke: would it be overly complicated to somehow multi-thread it? so one thread starts at the beginning, the other thread starts at the end, and they meet in the middle? | 00:45 | |
maybe threading isn't the right term. those concepts are pretty foreign to me | |||
00:46
kurahaupo left,
kurahaupo joined
|
|||
Voldenet | afair not many interpreters/compilers optimize that case when you call .length, .elems, .count or similar, because they assume mutability of the collection | 00:48 | |
MasterDuke | you'd have to be careful since it (generally) isn't safe to write to an array from multiple threads, but yeah, you could do that | ||
00:50
mcmillhj left
|
|||
MasterDuke | Voldenet: true. however, i don't think rakudo lifts any sort of sub/method call out | 00:50 | |
but i think it's just that the optimization hasn't been implemented yet, not that the language precludes it | 00:53 | ||

Voldenet | theoretically this should take forever | 01:10 | |

my @a = "Hello world".comb.Array; my $b = @a.elems; my @al = @a.unique.Array; my @c = @a.map({""}); loop { @c .= map({ @al.roll }); @c.join("").print; last if @c eq @a; "\r".print } | 01:17 | ||
this should run more ops/sec | |||
and it would probably be even faster if I just dropped the map | |||
Herby_ | can you work some parallel/async/concurrency magic on it? | ||
Voldenet | Hm, I am not sure if it's worth it | 01:18 | |
timotimo | you mean just put .race in one place and suddenly it's super fast? ;) | 01:21 | |

spacedbat | my next question: is there a way to run some code supplied on the command line, say via the -e flag, and lastly evaluate an expression to start the REPL? | 03:33 | |
03:38
mcmillhj joined
03:39
Zoffix joined
|
|||
spacedbat | any ideas how to start the repl from within a perl6 program, as though perl6 was run without arguments? | 03:40 | |
Zoffix | Kinda, but it involves using unsupported code | 03:41 | |
spacedbat | ah - what I'm aiming to do is print a banner when my emacs perl6 repl starts | ||
Zoffix | perl6 -e 'say "Look, ma! A banner!\n\n"; use nqp; nqp::getcomp("perl6").interactive' | 03:42 | |
spacedbat | timotimo suggested using -M but that would involve creating a file which complicates things a bit - ideally I'd be able to supply the banner as a -e one liner and go on to the repl | ||
ok, and nqp::getcomp is unsupported/likely to change? | |||
Zoffix | It is unsupported. It might change, dunno | 03:43 | |
03:43
mcmillhj left
|
|||
spacedbat | right... I've read some of your stuff online, I want to thank you for your works Zoffix | 03:43 | |
Zoffix | :) | 03:44 | |
spacedbat | ok that works a treat - I might support customizing the initialization of the repl so if the needed incantation changes it will be easy for users to adapt | 03:46 | |
Zoffix | spacedbat: or maybe this works too: perl6 -e 'say "A banner\n"; run $*EXECUTABLE' | 03:47 | |
a perl-within-perl | |||
more exactly: perl6 -e 'say "A banner\n"; my $ = run $*EXECUTABLE' | |||
(the second version doesn't sink the Proc so if someone types exit(42) in REPL there's no "The spawned process exited unsuccessfully" message | 03:48 | ||
) | |||
03:52
mcmillhj joined
|
|||
spacedbat | right, I was doing the $*EXECUTABLE trick before but to get the banner by passing it -v | 03:53 | |
however the banner then appeared later than I wanted it to | |||
thanks for the tip | 03:54 | ||
does perl6 have an equivalent of exec (replace current process?) | |||
Zoffix | nope | ||
03:55
mcmillhj_ joined
|
|||
spacedbat | maybe there's a posix lib, or I guess I could just nativecall it | 03:55 | |
Zoffix | As for appearing later. Hmm, maybe try setting $*OUT.out-buffer: False; before printing the banner. If you're not running with a tty STDOUT, it'll be buffered. | ||
"by passing it -v" what does that mean? | 03:56 | ||
spacedbat | by later I mean, it printed To exit type 'exit' or '^D' first | ||
then the banner | |||
I was doing this first thing after the repl started: say run($*EXECUTABLE.Str, '-v', :out).out.slurp-rest | 03:57 | ||
I'm an old hand at perl5 but a bit rusty, much less familiar with perl6 | 03:58 | ||

Zoffix | Seems to print fine when you pass the code in -e gist.github.com/zoffixznet/665f492...47bc9fa47d | 03:58 | |
There's also a switch to have a silent repl | |||
spacedbat | yes I noticed that, but I want this to be interactive | 03:59 | |
I like the run $*EXECUTABLE trick, but I'd rather not spawn an extra process that lingers | |||
04:00

spacedbat | there's a few things for me to try now, cheers | 04:00 | |
Kaiepi | node has a repl module to allow people to do this | ||
spacedbat | I noticed there is a REPL trait - seen a gist where someone made a custom repl | 04:02 | |
Zoffix | That might've been mine from awhile back when we had to workaround a bug that made it into the release | 04:04 | |
spacedbat | this was it: gist.github.com/regnarg/3b98a0b5f3...c1bb0da3ff | ||
04:05
mcmillhj left
|
|||
Zoffix | Ah | 04:05 | |
Well, it's using the same nqp::getcomp('perl6'); I showed above | |||
spacedbat | yes | ||
I don't need all that extra stuff, would like this to be vanilla perl6 repl with a banner to start with | 04:06 | ||
I'm going to contribute it to the perl6-mode for emacs | |||

todd | hi all. A mystery. This works: $ClipStr ~~ s:global/"\t"/"\n"/; for split( "\n", $ClipStr ) -> $Line { | 06:12 | |
but this does not: for split( "\t", $ClipStr ) -> $Line { | 06:13 | ||
or this for split( ord(9), $ClipStr ) -> $Line { | |||
Zoffix | What happens when it doesn't work? | 06:14 | |
06:16
mcmillhj left

todd | The whole $ClipStr gets transfered into only one $Line | 06:18 | |

camelia | Str $line = "foo" Str $line = "bar" |
||
Zoffix | What's the actual code you're using? | ||
todd | I forgot the name of that clipboard routing I can copy it onto the web | 06:20 | |
paste something or other | 06:21 | ||
Zoffix | I'm guessing you aren't actually using split the way you showed above and instead you stored the return value into a variable first which containerized it. Either bind it ($x := split) or decont it (for $x<>) | 06:22 | |

todd | for split( "\t", $ClipStr ) -> $Line { do something } | 06:28 | |
It did not split the string | |||

`þ".chop` is still chop. I am looking for a perl6 -e 'my $x="a b c d "; $x ~~ s///; say "<$x>";' | 08:50 | ||

thowe | I seem to recall a module or method to do exactly that in Perl5, but don't remember it. I've seen mst do it in code. | 14:30 | |
timotimo | use always refers to compunits | 14:31 | |
i.e. "use FooBar" can give you a "BleepBloop" if that's what's in the file that has that name | |||
El_Che | you'll loose namespacing that way | 14:38 | |
you want to keep namespacing, you just want a short way to reference in the consuming class | 14:39 | ||

AlexDaniel` | timotimo: oh, I know | 14:59 | |
Will fix once i'm back home | |||
thowe | so, I almost hate to ask, but there seemed to be some debate recently... Should I put "use v6.c;" at the top of my script? | 15:00 | |
timotimo | you can also put v6.d.PREVIEW if you're using "await" a bunch | ||
and you're okay with code migrating between threads | |||
thowe | SInce I don't grok what you just said, I won't. | 15:01 | |
Zoffix | thowe: it depends on your needs. `use v6.c` says "I want language version 6.c". So when new language features come out—like the stuff timotimo mentioned—your program won't have them available. This may be what you want, since you wrote the program for that specific language version, but you may also wish to always use the latest language version (which is what lack of `use v...` would use). Some people | 15:05 | |
also put it in to get more helpful errors if you accidentally run your perl6 script with perl compiler, but IME I found little use in that advice. | |||
