| rypervenche | I'm doing a .map on an array and I'd like to do something different for the first element than for the rest. Is there a better way to do this than to have a counter and check if it's == 1? | 01:04 | |
| guifa2 | not only having a counter, but you really need to be doing that with @array.kv.map | 01:26 | |
| I don't think there's a guarantee that maps are processed in order | |||
| m: <a b c d e>.kv.map( -> \k, \v { if k == 1 { "one" } else { v } } ) | 01:27 | ||

| moritz | JJMerelo: re RFC advent, do I need to take care to publish my stuff, or will you do that? | 08:14 | |
| JJMerelo | moritz please do it yourself. I can help you if you want, but you know the ropes already | ||
| moritz | JJMerelo: for which day? | 08:15 | |
| JJMerelo | moritz day 3. | 08:17 | |
| I'll ask Altai-man_ to program theirs for today | |||
| .tell Altai-man_ can you please program your post for today 1 minute after midnight? | 08:18 | ||
| tellable6 | JJMerelo, I'll pass your message to Altai-man_ | ||
| moritz | JJMerelo: roger, post scheduled | 08:22 | |
| JJMerelo | Thanks! | ||
| BTW, we're talking about the "20th anniversary calendar", started today rakuadventcalendar.wordpress.com/2...1-threads/ | |||
| moritz | JJMerelo: I'm pretty sure threads arrived in Perl 5 earlier than 5.10; I remember experimenting with them in 5.8.8 | 08:24 | |
| maybe even 5.6 had them | |||
| JJMerelo | moritz Maybe 5.8.8 was what I'm talking about | ||
| I'll edit that | 08:25 | ||
| BTW, just change the address to raku-advent.blog, which was donated by tbrowder | |||
| moritz changed to 5.8.8, thanks! | 08:26 | ||

| tobs | I feel like I should write another one, but for a short and sweet and implemented feature. | 09:05 | |
| mst | JJMerelo: 5.005 had what are now referred to as, well, 5005threads, then 5.6 switched to the ithreads model based on activestate's work emulating fork on win32 | 09:06 | |
| hmm | |||
| I'm sure -something- happened in 5.6 | |||
| but threads.pm itself went into core for 5.7.3 | |||
| leont | ithreads in 5.6 was only used for pseudoforking | ||
| mst | ah, and Thread.pm and the 5005thread model was still all you got for threading? | 09:07 | |
| leont | Yeah | ||
| 5.005 threads was closer to raku's threading model, except the interpreter wasn't thread-safe at all. This wasn't workable at all. | |||
| mst | here we go: perldoc.pl/Thread#HISTORY | ||
| right, 5.005threads were "what we would've liked to have except lolno" | 09:08 | ||
| leont | This is also why I was so upset with the Parrot people. They wrote a brand new VM, and didn't make it threadsafe from the start | ||
| mst | ithreads were "what actually worked given the constraints" | ||
| leont | ithreads kind of suck, but they were realistic | ||
| That decision in parrot was so dumb I can only describe it as incompetent. | 09:09 | ||
| mst | right, and IME I don't manage to segfault them noticeable more often than I do single threaded perl | ||
| leont | It's the thing that doomed it to never going to work | ||
|
09:09
JJMerelo left
|
|||
| mst | every time I looked at parrot it seemed to be in a new state of "we're rewriting everything from the ground up, get back to us" | 09:10 | |
| eventually I stopped checking | |||
| leont | Whereas in MoarVM it was thread-safe from the ground up. In particular the GC. | 09:12 | |
| moritz | it seems that projects that start with the premise of rewriting everything from scratch attract people who want to rewrite everything from scratch :D | 09:13 | |

| Also looking for a linter/static analysis tool | 13:41 | ||
| sena_kun | No separate tool, but Comma partly solves this. | 13:44 | |

| guifa2 | Arg | 15:24 | |
| Finally get my localtime functions to work and now I can't get the wrapping on DateTime to go | 15:25 | ||
| Is there a way to, when wrapping a function, also add additionally arguments to it? | 15:27 | ||
| m: class A { method foo { "bar" } }; A.^find_method('foo').wrap( method ($a) { 'foo' ~ callsame ~ $a }); say A.new.foo; | 15:28 | ||
| camelia | Too few positionals passed; expected 2 arguments but got 1 in method <anon> at <tmp> line 1 in block <unit> at <tmp> line 1 |
||
| guifa2 | So not enough arguments there but… | ||
| m: class A { method foo { "bar" } }; A.^find_method('foo').wrap( method ($a) { 'foo' ~ callsame ~ $a }); say A.new.foo('xyz') | |||
| camelia | Too many positionals passed; expected 0 arguments but got 1 in method <anon> at <tmp> line 1 in block <unit> at <tmp> line 1 |
||
| guifa2 | Now we've got too many =\ | ||

|
|||
| guifa2 | Basically, it seems like when you wrap a function, the signature restraints are still imposed and can result in die messages when (I don't think) there should be | 15:32 | |
| gfldex | guifa2: you are doing callsame on a method that doesn't want any arguments | ||
| m: class A { method foo { "bar" } }; A.^find_method('foo').wrap( method ($a) { 'foo' ~ callwith() ~ $a }); say A.new.foo('xyz') | 15:33 | ||
| camelia | Too few positionals passed; expected 1 argument but got 0 in method foo at <tmp> line 1 in method <anon> at <tmp> line 1 in block <unit> at <tmp> line 1 |
||
| guifa2 | I was just about to type it doesn't change with callwith =\ | ||
| I'm trying to add a named argument to DateTime's new() but at runtime it always balks when it sees the new one | 15:35 | ||
| gfldex | guifa2: when wrapping things, sometimes a BEGIN helps. | 15:36 | |
| guifa2 | hmm, hopefully that won't muck with precompilation | 15:37 | |
| whelp, actually that didn't help =\ still getting unexpected named parameter | 15:38 | ||
| gfldex | guifa2: in that case you might need INIT | ||

| guifa2 | ugh, I might need a new approach entirely. I wanted to use wrap so I could stay in runtime and not breakprecompilation but i'm not sure if this is by design or an error | 15:46 | |
